<h3>Interactive improvements<a class="headerlink" href="#interactive-improvements" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>The title of the terminal tab can now be set separately from the window title by defining the <a class="reference internal" href="cmds/fish_tab_title.html"><span class="doc">fish_tab_title</span></a> function (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2692">#2692</a>).</p></li>
<li><p>fish now hides the portion of a multiline prompt that is scrolled out of view due to a huge command line. This prevents duplicate lines after repainting with partially visible prompt (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11911">#11911</a>).</p></li>
<li><p><a class="reference internal" href="cmds/fish_config.html"><span class="doc">fish_config prompt</span></a>’s <code class="docutils literal notranslate"><span class="pre">choose</span></code> and <code class="docutils literal notranslate"><span class="pre">save</span></code> subcommands have been taught to reset <a class="reference internal" href="cmds/fish_mode_prompt.html"><span class="doc">fish_mode_prompt</span></a> in addition to the other prompt functions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11937">#11937</a>).</p></li>
<li><p>fish no longer force-disables mouse capture (DECSET/DECRST 1000),
so you can use those commands
to let mouse clicks move the cursor or select completions items (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4918">#4918</a>).</p></li>
<li><p>The <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">p</kbd> binding no longer adds a redundant space to the command line.</p></li>
<li><p>When run as a login shell on macOS, fish now sets <span class="target" id="index-0"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">MANPATH</span></code> correctly when that variable was already present in the environment (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10684">#10684</a>).</p></li>

<li><p>A MSYS2-specific workaround for Konsole and WezTerm has been added,

<li><p>Release tags and source code tarballs are GPG-signed again (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11996">#11996</a>).</p></li>
<li><p>Documentation in release tarballs is now built with the latest version of Sphinx,
which means that pre-built man pages include <a class="reference internal" href="terminal-compatibility.html#term-compat-osc-8"><span class="std std-ref">OSC 8 hyperlinks</span></a>.</p></li>
<li><p>The Sphinx dependency is now specified in <code class="docutils literal notranslate"><span class="pre">pyproject.toml</span></code>,
which allows you to use <a class="reference external" href="https://github.com/astral-sh/uv">uv</a> to provide Sphinx for building documentation (e.g. <code class="docutils literal notranslate"><span class="pre">uv</span> <span class="pre">run</span> <span class="pre">cargo</span> <span class="pre">install</span> <span class="pre">--path</span> <span class="pre">.</span></code>).</p></li>
<li><p>The minimum supported Rust version (MSRV) has been updated to 1.85.</p></li>
<li><p>The standalone build mode has been made the default.
This means that the files in <code class="docutils literal notranslate"><span class="pre">$CMAKE_INSTALL_PREFIX/share/fish</span></code> will not be used anymore, except for HTML docs.
As a result, future upgrades will no longer break running shells
if one of fish’s internal helper functions has been changed in the updated version.
For now, the data files are still installed redundantly,
to prevent upgrades from breaking already-running shells (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11921">#11921</a>).
To reverse this change (which should not be necessary),
patch out the <code class="docutils literal notranslate"><span class="pre">embed-data</span></code> feature from <code class="docutils literal notranslate"><span class="pre">cmake/Rust.cmake</span></code>.
This option will be removed in future.</p></li>
<li><p>OpenBSD 7.8 revealed an issue with fish’s approach for displaying builtin man pages, which has been fixed.</p></li>

<h2>fish 4.1.1 (released September 30, 2025)<a class="headerlink" href="#fish-4-1-1-released-september-30-2025" title="Link to this heading">¶</a></h2>
<p>This release fixes the following regressions identified in 4.1.0:</p>
<ul>
<li><p>Many of our new Chinese translations were more confusing than helpful; they have been fixed or removed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11833">#11833</a>).</p>
<p>Note that you can work around this type of issue by configuring fish’s <a class="reference internal" href="cmds/_.html"><span class="doc">message localization</span></a>:
if your environment contains something like <code class="docutils literal notranslate"><span class="pre">LANG=zh_CN.UTF-8</span></code>,
you can use <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-g</span> <span class="pre">LC_MESSAGES</span> <span class="pre">en</span></code> to use English messages inside fish.
This will not affect fish’s child processes unless <code class="docutils literal notranslate"><span class="pre">LC_MESSAGES</span></code> was already exported.</p>
</li>
<li><p>Some <a class="reference internal" href="cmds/fish_config.html"><span class="doc">fish_config</span></a> subcommands for showing prompts and themes had been broken in standalone Linux builds (those using the <code class="docutils literal notranslate"><span class="pre">embed-data</span></code> cargo feature), which has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11832">#11832</a>).</p></li>
<li><p>On Windows Terminal, we observed an issue where fish would fail to read the terminal’s response to our new startup queries, causing noticeable lags and a misleading error message. A workaround has been added (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11841">#11841</a>).</p></li>
<li><p>A WezTerm <a class="reference external" href="https://github.com/wezterm/wezterm/issues/6087">issue breaking shifted key input</a> has resurfaced on some versions of WezTerm; our workaround has been extended to cover all versions for now (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11204">#11204</a>).</p></li>
<li><p>Fixed a crash in <a class="reference internal" href="cmds/fish_config.html"><span class="doc">the web-based configuration tool</span></a> when using the new underline styles (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11840">#11840</a>).</p></li>

<li><p>fish now supports transient prompts: if <span class="target" id="index-1"></span><a class="reference internal" href="language.html#envvar-fish_transient_prompt"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_transient_prompt</span></code></a> is set to 1, fish will reexecute prompt functions with the <code class="docutils literal notranslate"><span class="pre">--final-rendering</span></code> argument before running a commandline (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11153">#11153</a>).</p></li>
<li><p>Tab completion results are truncated up to the common directory path, instead of somewhere inside that path. E.g. if you complete “share/functions”, and it includes the files “foo.fish” and “bar.fish”,
the completion pager will now show “…/foo.fish” and “…/bar.fish” (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11250">#11250</a>).</p></li>
<li><p>Self-installing builds as created by e.g. <code class="docutils literal notranslate"><span class="pre">cargo</span> <span class="pre">install</span></code> no longer install other files, see <a class="reference internal" href="#changelog-4-1-embedded"><span class="std std-ref">below</span></a>.</p></li>
<li><p>Our gettext-based message-localization has been reworked,
adding translations to self-installing builds; see <a class="reference internal" href="#changelog-4-1-gettext"><span class="std std-ref">below</span></a>.</p></li>

<ul>
<li><p><code class="docutils literal notranslate"><span class="pre">set_color</span> <span class="pre">--background=COLOR</span></code> no longer implicitly activates bold mode.
If your theme is stored in universal variables (the historical default), some bold formatting might be lost.

<li><p>Terminfo-style key names (<code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">-k</span> <span class="pre">nul</span></code>) are no longer supported. They had been superseded by fish’s <a class="reference internal" href="cmds/bind.html"><span class="doc">own key names</span></a> since 4.0 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11342">#11342</a>).</p></li>
<li><p>fish no longer reads the terminfo database, so its behavior is generally no longer affected by the <span class="target" id="index-2"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">TERM</span></code> environment variable (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11344">#11344</a>).
For the time being, this change can be reversed via the <code class="docutils literal notranslate"><span class="pre">ignore-terminfo</span></code> <a class="reference internal" href="language.html#featureflags"><span class="std std-ref">feature flag</span></a>.
To do so, run the following once and restart fish:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">set</span><span class="w"> </span><span class="no">-Ua</span><span class="w"> </span><span class="no">fish_features</span><span class="w"> </span><span class="no">no-ignore-terminfo</span>
</pre></div>
</div>
</li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">--install</span></code> option when fish is built as self-installing is removed, see <a class="reference internal" href="#changelog-4-1-embedded"><span class="std std-ref">below</span></a>.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set_color</span> <span class="pre">ff0000</span></code> now outputs 24-bit RGB true-color even if <span class="target" id="index-3"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">COLORTERM</span></code> is unset.
One can override this by setting <span class="target" id="index-4"></span><a class="reference internal" href="language.html#envvar-fish_term24bit"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_term24bit</span></code></a> to 0 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11372">#11372</a>).</p></li>
<li><p>fish now requires the terminal to respond to queries for the <a class="reference internal" href="terminal-compatibility.html#term-compat-primary-da"><span class="std std-ref">Primary Device Attribute</span></a>.
For now, this can be reversed via a <a class="reference internal" href="language.html#featureflags"><span class="std std-ref">feature flag</span></a>,
by running (once) <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-Ua</span> <span class="pre">fish_features</span> <span class="pre">no-query-term</span></code> and restarting fish.</p></li>

<span id="changelog-4-1-embedded"></span><h3>Changes to self-installing builds<a class="headerlink" href="#changes-to-self-installing-builds" title="Link to this heading">¶</a></h3>
<p>The self-installing build type introduced in fish 4.0 has been changed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11143">#11143</a>).
Now fish built with embedded data will just read the data straight from its own binary or write it out to temporary files when necessary, instead of requiring an installation step on start.
That means it is now possible to build fish as a single file and copy it to any system with a compatible CPU architecture, including as a different user, without extracting any files.
As before, this is the default when building via <code class="docutils literal notranslate"><span class="pre">cargo</span></code>, and disabled when building via CMake.
For packagers we continue to recommend CMake.</p>
<p>Note: When fish is built like this, the <span class="target" id="index-7"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">__fish_data_dir</span></code> variable will be empty because that directory no longer has meaning.
You should generally not need these files.
For example, if you want to make sure that completions for “foo” are loaded, use <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">-C"foo</span> <span class="pre">"</span> <span class="pre">>/dev/null</span></code> instead).
The raw files are still exposed via <a class="reference internal" href="cmds/status.html#status-get-file"><span class="std std-ref">status subcommands</span></a>, mainly for fish’s internal use, but you can also use them as a last resort.</p>
<p>Remaining benefits of a full installation (as currently done by CMake) are:</p>
<ul class="simple">
<li><p>man pages like <code class="docutils literal notranslate"><span class="pre">fish(1)</span></code> in standard locations, easily accessible from outside fish.</p></li>
<li><p>a local copy of the HTML documentation, typically accessed via the <a class="reference internal" href="cmds/help.html"><span class="doc">help</span></a> function.
In builds with embedded data, <code class="docutils literal notranslate"><span class="pre">help</span></code> will redirect to e.g. <a class="reference external" href="https://fishshell.com/docs/current/">https://fishshell.com/docs/current/</a></p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_indent</span></code> and <code class="docutils literal notranslate"><span class="pre">fish_key_reader</span></code> as separate files, making them easily accessible outside fish</p></li>
<li><p>an (empty) <code class="docutils literal notranslate"><span class="pre">/etc/fish/config.fish</span></code> as well as empty directories <code class="docutils literal notranslate"><span class="pre">/etc/fish/{functions,completions,conf.d}</span></code></p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">$PREFIX/share/pkgconfig/fish.pc</span></code>, which defines directories for configuration-snippets, like <code class="docutils literal notranslate"><span class="pre">vendor_completions.d</span></code></p></li>
</ul>

<section id="changes-to-gettext-localization">
<span id="changelog-4-1-gettext"></span><h3>Changes to gettext localization<a class="headerlink" href="#changes-to-gettext-localization" title="Link to this heading">¶</a></h3>
<p>We replaced several parts of the gettext functionality with custom implementations (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11726">#11726</a>).
Most notably, message extraction, which should now work reliably, and the runtime implementation, where we no longer dynamically link to gettext, but instead use our own implementation, whose behavior is similar to GNU gettext, with some <a class="reference internal" href="cmds/_.html"><span class="doc">minor deviations</span></a>.
Our implementation now fully respects fish variables, so locale variables do not have to be exported for fish localizations to work.
They still have to be exported to inform other programs about language preferences.
The <span class="target" id="index-8"></span><a class="reference internal" href="language.html#envvar-LANGUAGE"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">LANGUAGE</span></code></a> environment variable is now treated as a path variable, meaning it is an implicitly colon-separated list.
While we no longer have any runtime dependency on gettext, we still need gettext tools for building, most notably <code class="docutils literal notranslate"><span class="pre">msgfmt</span></code>.
When building without <code class="docutils literal notranslate"><span class="pre">msgfmt</span></code> available, localization will not work with the resulting executable.
Localization data is no longer sourced at runtime from MO files on the file system, but instead built into the executable.
This is always done, independently of the other data embedding, so all fish executables will have access to all message catalogs, regardless of the state of the file system.
Disabling our new <code class="docutils literal notranslate"><span class="pre">localize-messages</span></code> cargo feature will cause fish to be built without localization support.
CMake builds can continue to use the <code class="docutils literal notranslate"><span class="pre">WITH_GETTEXT</span></code> option, with the same semantics as the <code class="docutils literal notranslate"><span class="pre">localize-messages</span></code> feature.
The current implementation does not provide any configuration options for controlling which language catalogs are built into the executable (other than disabling them all).
As a workaround, you can delete files in the <code class="docutils literal notranslate"><span class="pre">po</span></code> directory before building to exclude unwanted languages.</p>

<h2>fish 4.0.6 (released September 12, 2025)<a class="headerlink" href="#fish-4-0-6-released-september-12-2025" title="Link to this heading">¶</a></h2>
<p>This release of fish fixes a number of issues identified in fish 4.0.2:</p>
<ul class="simple">
<li><p>fish now properly inherits $PATH under Windows WSL2 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11354">#11354</a>).</p></li>
<li><p>Remote filesystems are detected properly again on non-Linux systems.</p></li>
<li><p>the <a class="reference internal" href="cmds/printf.html"><span class="doc">printf</span></a> builtin no longer miscalculates width of multi-byte characters (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11412">#11412</a>).</p></li>
<li><p>For many years, fish has been “relocatable” -- it was possible to move the entire <code class="docutils literal notranslate"><span class="pre">CMAKE_INSTALL_PREFIX</span></code> and fish would use paths relative to its binary.
Only gettext locale paths were still determined purely at compile time, which has been fixed.</p></li>
<li><p>the <a class="reference internal" href="cmds/commandline.html"><span class="doc">commandline</span></a> builtin failed to print the commandline set by a <code class="docutils literal notranslate"><span class="pre">commandline</span> <span class="pre">-C</span></code> invocation, which broke some completion scripts.
This has been corrected (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11423">#11423</a>).</p></li>
<li><p>To work around terminals that fail to parse Operating System Command (OSC) sequences, a temporary feature flag has been added.
It allows you to disable prompt marking (OSC 133) by running (once) <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-Ua</span> <span class="pre">fish_features</span> <span class="pre">no-mark-prompt</span></code> and restarting fish (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11749">#11749</a>).</p></li>
<li><p>The routines to save history and universal variables have seen some robustness improvements.</p></li>
<li><p>builtin <a class="reference internal" href="cmds/status.html"><span class="doc">status current-command</span></a> no longer prints a trailing blank line.</p></li>
<li><p>A crash displaying multi-line quoted command substitutions has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11444">#11444</a>).</p></li>
<li><p>Commands like <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">fish_complete_path</span> <span class="pre">...</span></code> accidentally disabled completion autoloading, which has been corrected.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">nmcli</span></code> completions have been fixed to query network information dynamically instead of only when completing the first time.</p></li>
<li><p>Git completions no longer print an error when no <cite>git-foo</cite> executable is in <span class="target" id="index-13"></span><a class="reference internal" href="language.html#envvar-PATH"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">PATH</span></code></a>.</p></li>

on a command-line like <code class="docutils literal notranslate"><span class="pre">foo</span> <span class="pre">--long=</span></code> have been invalidated by a change in 4.0; the completion scripts have been adjusted accordingly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11508">#11508</a>).</p></li>
<li><p>Some completions were misinterpreted, which caused garbage to be displayed in the completion list. This has been fixed.</p></li>
<li><p>fish no longer interprets invalid control sequences from the terminal as if they were <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">[</kbd> or <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">o</kbd> key strokes.</p></li>

<li><p><kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">delete</kbd> now deletes the word right of the cursor.</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">h</kbd> erases the last word again (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11548">#11548</a>).</p></li>

(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11479">#11479</a>).</p></li>
<li><p>Key bindings like <code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">shift-A</span></code> are no longer accepted; use <code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">shift-a</span></code> or <code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">A</span></code>.</p></li>
<li><p>Key bindings like <code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">shift-a</span></code> take precedence over <code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">A</span></code> when the key event included the shift modifier.</p></li>
<li><p>Bindings using shift with non-ASCII letters (such as <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">shift</kbd>-<kbd class="kbd docutils literal notranslate">ä</kbd>) are now supported.</p></li>
<li><p>Bindings with modifiers such as <code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">ctrl-w</span></code> work again on non-Latin keyboard layouts such as a Russian one.
This is implemented by allowing key events such as <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">ц</kbd> to match bindings of the corresponding Latin key, using the kitty keyboard protocol’s base layout key (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11520">#11520</a>).</p></li>
<li><p>Vi mode: The cursor position after pasting via <kbd class="kbd docutils literal notranslate">p</kbd> has been corrected.</p></li>
<li><p>Vi mode: Trying to replace the last character via <kbd class="kbd docutils literal notranslate">r</kbd> no longer replaces the last-but-one character (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11484">#11484</a>).</p></li>

<h2>fish 4.0.2 (released April 20, 2025)<a class="headerlink" href="#fish-4-0-2-released-april-20-2025" title="Link to this heading">¶</a></h2>
<p>This release of fish fixes a number of issues identified in fish 4.0.1:</p>
<ul class="simple">
<li><p>Completions are quoted, rather than backslash-escaped, only if the completion is unambiguous. Continuing to edit the token is therefore easier (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11271">#11271</a>). This changes the behavior introduced in 4.0.0 where all completions were quoted.</p></li>
<li><p>The warning when the terminfo database can’t be found has been downgraded to a log message. fish will act as if the terminal behaves like xterm-256color, which is correct for the vast majority of cases (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11277">#11277</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11290">#11290</a>).</p></li>
<li><p>Key combinations using the super (Windows/command) key can now (actually) be bound using the <kbd class="kbd docutils literal notranslate">super-</kbd> prefix (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11217">#11217</a>). This was listed in the release notes for 4.0.1 but did not work correctly.</p></li>
<li><p><a class="reference internal" href="cmds/function.html"><span class="doc">function</span></a> is stricter about argument parsing, rather than allowing additional parameters to be silently ignored (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11295">#11295</a>).</p></li>
<li><p>Using parentheses in the <a class="reference internal" href="cmds/test.html"><span class="doc">test</span></a> builtin works correctly, following a regression in 4.0.0 where they were not recognized (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11387">#11387</a>).</p></li>
<li><p><kbd class="kbd docutils literal notranslate">delete</kbd> in Vi mode when Num Lock is active will work correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11303">#11303</a>).</p></li>

<li><p>A number of crashes have been fixed.

<li><p>A race condition in the test suite has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11254">#11254</a>), and a test for fish versioning relaxed to support downstream distributors’ modifications (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11173">#11173</a>).</p></li>

<h2>fish 4.0.0 (released February 27, 2025)<a class="headerlink" href="#fish-4-0-0-released-february-27-2025" title="Link to this heading">¶</a></h2>
<p>fish’s core code has been ported from C++ to Rust (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9512">#9512</a>). This means a large change in dependencies and how to build fish. However, there should be no direct impact on users. Packagers should see the <a class="reference internal" href="#rust-packaging"><span class="std std-ref">For Distributors</span></a> section at the end.</p>
<section id="notable-backwards-incompatible-changes">
<h3>Notable backwards-incompatible changes<a class="headerlink" href="#notable-backwards-incompatible-changes" title="Link to this heading">¶</a></h3>
<ul>
<li><p>As part of a larger binding rework, <code class="docutils literal notranslate"><span class="pre">bind</span></code> gained a new key notation.
In most cases the old notation should keep working, but in rare cases you may have to change a <code class="docutils literal notranslate"><span class="pre">bind</span></code> invocation to use the new notation.
See <a class="reference internal" href="#changelog-4-0-new-bindings"><span class="std std-ref">below</span></a> for details.</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">c</kbd> now calls a new bind function called <code class="docutils literal notranslate"><span class="pre">clear-commandline</span></code>. The old behavior, which leaves a “^C” marker, is available as <code class="docutils literal notranslate"><span class="pre">cancel-commandline</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10935">#10935</a>)</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">random</span></code> will produce different values from previous versions of fish when used with the same seed, and will work more sensibly with small seed numbers.
The seed was never guaranteed to give the same result across systems,
so we do not expect this to have a large impact (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9593">#9593</a>).</p></li>
<li><p>Variables in command position that expand to a subcommand keyword are now forbidden to fix a likely user error.
For example, <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">editor</span> <span class="pre">command</span> <span class="pre">emacs;</span> <span class="pre">$editor</span></code> is no longer allowed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10249">#10249</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">functions</span> <span class="pre">--handlers</span></code> will now list handlers in a different order.
Now it is definition order, first to last, where before it was last to first.
This was never specifically defined, and we recommend not relying on a specific order (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9944">#9944</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">qmark-noglob</span></code> feature, introduced in fish 3.0, is enabled by default. That means <code class="docutils literal notranslate"><span class="pre">?</span></code> will no longer act as a single-character glob.
You can, for the time being, turn it back on by adding <code class="docutils literal notranslate"><span class="pre">no-qmark-noglob</span></code> to <span class="target" id="index-14"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_features</span></code> and restarting fish:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">set</span><span class="w"> </span><span class="no">-Ua</span><span class="w"> </span><span class="no">fish_features</span><span class="w"> </span><span class="no">no-qmark-noglob</span>
</pre></div>
</div>
<p>The flag will eventually be made read-only, making it impossible to turn off.</p>
</li>
<li><p>Terminals that fail to ignore unrecognized OSC or CSI sequences may display garbage. We know cool-retro-term and emacs’ ansi-term are affected, but most mainstream terminals are not.</p></li>
<li><p>fish no longer searches directories from the Windows system/user <code class="docutils literal notranslate"><span class="pre">$PATH</span></code> environment variable for Linux executables. To execute Linux binaries by name (i.e. not with a relative or absolute path) from a Windows folder, make sure the <code class="docutils literal notranslate"><span class="pre">/mnt/c/...</span></code> path is explicitly added to <code class="docutils literal notranslate"><span class="pre">$fish_user_paths</span></code> and not just automatically appended to <code class="docutils literal notranslate"><span class="pre">$PATH</span></code> by <code class="docutils literal notranslate"><span class="pre">wsl.exe</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10506">#10506</a>).</p></li>
<li><p>Under Microsoft Windows Subsystem for Linux 1 (not WSL 2), backgrounded jobs that have not been disowned and do not terminate on their own after a <code class="docutils literal notranslate"><span class="pre">SIGHUP</span></code> + <code class="docutils literal notranslate"><span class="pre">SIGCONT</span></code> sequence will be explicitly killed by fish on exit (after the usual prompt to close or disown them) to work around a WSL 1 deficiency that sees backgrounded processes that run into <code class="docutils literal notranslate"><span class="pre">SIGTTOU</span></code> remain in a suspended state indefinitely (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5263">#5263</a>).

<h3>Notable improvements and fixes<a class="headerlink" href="#id4" title="Link to this heading">¶</a></h3>
<ul id="changelog-4-0-new-bindings">
<li><p>fish now requests XTerm’s <code class="docutils literal notranslate"><span class="pre">modifyOtherKeys</span></code> keyboard encoding and <a class="reference external" href="https://sw.kovidgoyal.net/kitty/keyboard-protocol/">kitty keyboard protocol’s</a> progressive enhancements (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10359">#10359</a>).
Depending on terminal support, this allows to binding more key combinations, including arbitrary combinations of modifiers <kbd class="kbd docutils literal notranslate">ctrl</kbd>, <kbd class="kbd docutils literal notranslate">alt</kbd> and <kbd class="kbd docutils literal notranslate">shift</kbd>, and distinguishing (for example) <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">i</kbd> from <kbd class="kbd docutils literal notranslate">tab</kbd>.</p>
<p>Additionally, <code class="docutils literal notranslate"><span class="pre">bind</span></code> now supports a human-readable syntax in addition to byte sequences.
This includes modifier names, and names for keys like <kbd class="kbd docutils literal notranslate">enter</kbd> and <kbd class="kbd docutils literal notranslate">backspace</kbd>.
For example</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">up</span> <span class="pre">'do</span> <span class="pre">something'</span></code> binds the up-arrow key instead of a two-key sequence (“u” and then “p”)</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">ctrl-x,alt-c</span> <span class="pre">'do</span> <span class="pre">something'</span></code> binds a sequence of two keys.</p></li>
</ul>
<p>Any key argument that starts with an ASCII control character (like <code class="docutils literal notranslate"><span class="pre">\e</span></code> or <code class="docutils literal notranslate"><span class="pre">\cX</span></code>) or is up to 3 characters long, not a named key, and does not contain <code class="docutils literal notranslate"><span class="pre">,</span></code> or <code class="docutils literal notranslate"><span class="pre">-</span></code> will be interpreted in the old syntax to keep compatibility for the majority of bindings.</p>
<p>Keyboard protocols can be turned off by disabling the “keyboard-protocols” feature flag:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">set</span><span class="w"> </span><span class="no">-Ua</span><span class="w"> </span><span class="no">fish_features</span><span class="w"> </span><span class="no">no-keyboard-protocols</span>
</pre></div>
</div>
<p>This is a temporary measure to work around buggy terminals (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11056">#11056</a>), which appear to be relatively rare.
Use this if something like “=0” or “=5u” appears in your commandline mysteriously.</p>
</li>
<li><p>fish can now be built as a self-installing binary (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10367">#10367</a>). That means it can be easily built on one system and copied to another, where it can extract supporting files.
To do this, run:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">cargo</span><span class="w"> </span><span class="no">install</span><span class="w"> </span><span class="no">--path</span><span class="w"> </span><span class="no">.</span><span class="w"> </span><span class="c"># in a clone of the fish repository</span>
<span class="c"># or `cargo build --release` and copy target/release/fish{,_indent,_key_reader} wherever you want</span>
</pre></div>
</div>
<p>The first time it runs interactively, it will extract all the data files to <code class="docutils literal notranslate"><span class="pre">~/.local/share/fish/install/</span></code>. A specific path can be used for the data files with <code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--install=PATH</span></code> To uninstall, remove the fish binaries and that directory.</p>
<p>This build system is experimental; the main build system, using <code class="docutils literal notranslate"><span class="pre">cmake</span></code>, remains the recommended approach for packaging and installation to a prefix.</p>
</li>
<li><p>A new function <code class="docutils literal notranslate"><span class="pre">fish_should_add_to_history</span></code> can be overridden to decide whether a command should be added to the history (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10302">#10302</a>).</p></li>
<li><p>Bindings can now mix special input functions and shell commands, so <code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">ctrl-g</span> <span class="pre">expand-abbr</span> <span class="pre">"commandline</span> <span class="pre">-i</span> <span class="pre">\n"</span></code> works as expected (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8186">#8186</a>).</p></li>
<li><p>Special input functions run from bindings via <code class="docutils literal notranslate"><span class="pre">commandline</span> <span class="pre">-f</span></code> are now applied immediately, instead of after the currently executing binding (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3031">#3031</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10126">#10126</a>).
For example, <code class="docutils literal notranslate"><span class="pre">commandline</span> <span class="pre">-i</span> <span class="pre">foo;</span> <span class="pre">commandline</span> <span class="pre">|</span> <span class="pre">grep</span> <span class="pre">foo</span></code> succeeds now.</p></li>
<li><p>Undo history is no longer truncated after every command, but kept for the lifetime of the shell process.</p></li>
<li><p>The <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">r</kbd> history search now uses glob syntax (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10131">#10131</a>).</p></li>
<li><p>The <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">r</kbd> history search now operates only on the line or command substitution at cursor, making it easier to combine commands from history (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9751">#9751</a>).</p></li>
<li><p>Abbreviations can now be restricted to specific commands. For instance:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">abbr</span><span class="w"> </span><span class="no">--add</span><span class="w"> </span><span class="no">--command</span><span class="w"> </span><span class="no">git</span><span class="w"> </span><span class="no">back</span><span class="w"> </span><span class="s1">'reset --hard HEAD^'</span>
</pre></div>
</div>
<p>will expand “back” to <code class="docutils literal notranslate"><span class="pre">reset</span> <span class="pre">--hard</span> <span class="pre">HEAD^</span></code>, but only when the command is <code class="docutils literal notranslate"><span class="pre">git</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9411">#9411</a>).</p>

<h3>Deprecations and removed features<a class="headerlink" href="#id5" title="Link to this heading">¶</a></h3>
<ul>
<li><p><code class="docutils literal notranslate"><span class="pre">commandline</span> <span class="pre">--tokenize</span></code> (short option <code class="docutils literal notranslate"><span class="pre">-o</span></code>) has been deprecated in favor of <code class="docutils literal notranslate"><span class="pre">commandline</span> <span class="pre">--tokens-expanded</span></code> (short option <code class="docutils literal notranslate"><span class="pre">-x</span></code>) which expands variables and other shell syntax, removing the need to use <a class="reference internal" href="cmds/eval.html"><span class="doc">eval</span></a> in completion scripts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10212">#10212</a>).</p></li>
<li><p>Two new feature flags:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">remove-percent-self</span></code> (see <code class="docutils literal notranslate"><span class="pre">status</span> <span class="pre">features</span></code>) disables PID expansion of <code class="docutils literal notranslate"><span class="pre">%self</span></code>, which has been supplanted by <code class="docutils literal notranslate"><span class="pre">$fish_pid</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10262">#10262</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">test-require-arg</span></code> disables <code class="docutils literal notranslate"><span class="pre">test</span></code>’s one-argument mode. That means <code class="docutils literal notranslate"><span class="pre">test</span> <span class="pre">-n</span></code> without an additional argument will return false, <code class="docutils literal notranslate"><span class="pre">test</span> <span class="pre">-z</span></code> will keep returning true. Any other option without an argument, anything that is not an option and no argument will be an error. This also goes for <code class="docutils literal notranslate"><span class="pre">[</span></code>, test’s alternate name.
This is a frequent source of confusion and so we are breaking with POSIX explicitly in this regard.
In addition to the feature flag, there is a debug category “deprecated-test”. Running fish with <code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">-d</span> <span class="pre">deprecated-test</span></code> will show warnings whenever a <code class="docutils literal notranslate"><span class="pre">test</span></code> invocation that would change is used. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10365">#10365</a>).</p></li>
</ul>
<p>These can be enabled with:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">set</span><span class="w"> </span><span class="no">-Ua</span><span class="w"> </span><span class="no">fish_features</span><span class="w"> </span><span class="no">remove-percent-self</span><span class="w"> </span><span class="no">test-require-arg</span>
</pre></div>
</div>
<p>We intend to enable them by default in future, and after that eventually make them read-only.</p>
</li>
<li><p>Specifying key names as terminfo names (using the <code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">-k</span></code> syntax) is deprecated and may be removed in a future version.</p></li>
<li><p>When a terminal pastes text into fish using bracketed paste, fish used to switch to a special <code class="docutils literal notranslate"><span class="pre">paste</span></code> bind mode.
This bind mode has been removed. The behavior on paste is no longer configurable.</p></li>
<li><p>When an interactive fish is stopped or terminated by a signal that cannot be caught (SIGSTOP or SIGKILL), it may leave the terminal in a state where keypresses with modifiers are sent as CSI u sequences, instead of traditional control characters or escape sequences that are recognized by Readline and compatible programs, such as bash and python.
If this happens, you can use the <code class="docutils literal notranslate"><span class="pre">reset</span></code> command from <code class="docutils literal notranslate"><span class="pre">ncurses</span></code> to restore the terminal state.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_key_reader</span> <span class="pre">--verbose</span></code> no longer shows timing information.</p></li>
<li><p>Terminal information is no longer read from hashed terminfo databases, or termcap databases (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10269">#10269</a>). The vast majority of systems use a non-hashed terminfo database, which is still supported.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">source</span></code> returns an error if used without a filename or pipe/redirection (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10774">#10774</a>).</p></li>
</ul>

<h3>Scripting improvements<a class="headerlink" href="#id6" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">for</span></code> loops will no longer remember local variables from the previous iteration (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10525">#10525</a>).</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">append</span></code> subcommand appends a command to the history, without executing it (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4506">#4506</a>).</p></li>
<li><p>A new redirection: <code class="docutils literal notranslate"><span class="pre"><?</span> <span class="pre">/path/to/file</span></code> will try opening the file as input, and if it doesn’t succeed silently uses <code class="docutils literal notranslate"><span class="pre">/dev/null</span></code> instead.
This can help with checks like <code class="docutils literal notranslate"><span class="pre">test</span> <span class="pre">-f</span> <span class="pre">/path/to/file;</span> <span class="pre">and</span> <span class="pre">string</span> <span class="pre">replace</span> <span class="pre">foo</span> <span class="pre">bar</span> <span class="pre"><</span> <span class="pre">/path/to/file</span></code>. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10387">#10387</a>)</p></li>
<li><p>A new option <code class="docutils literal notranslate"><span class="pre">commandline</span> <span class="pre">--tokens-raw</span></code> prints a list of tokens without any unescaping (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10212">#10212</a>).</p></li>
<li><p>A new option <code class="docutils literal notranslate"><span class="pre">commandline</span> <span class="pre">--showing-suggestion</span></code> tests whether an autosuggestion is currently displayed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10586">#10586</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">functions</span></code> and <code class="docutils literal notranslate"><span class="pre">type</span></code> now show that a function was copied and its source, rather than solely <code class="docutils literal notranslate"><span class="pre">Defined</span> <span class="pre">interactively</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6575">#6575</a>).</p></li>
<li><p>Stack trace now shows line numbers for copied functions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6575">#6575</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">foo</span> <span class="pre">&</span> <span class="pre">&&</span> <span class="pre">bar</span></code> is now a syntax error, like in other shells (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9911">#9911</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">if</span> <span class="pre">-e</span> <span class="pre">foo;</span> <span class="pre">end</span></code> now prints a more accurate error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10000">#10000</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">cd</span></code> into a directory that is not readable but accessible (permissions <code class="docutils literal notranslate"><span class="pre">--x</span></code>) is now possible (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10432">#10432</a>).</p></li>
<li><p>An integer overflow in <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">repeat</span></code> leading to a near-infinite loop has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9899">#9899</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">shorten</span></code> behaves better in the presence of non-printable characters, including fixing an integer overflow that shortened strings more than intended (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9854">#9854</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">pad</span></code> no longer allows non-printable characters as padding (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9854">#9854</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">repeat</span></code> now allows omission of <code class="docutils literal notranslate"><span class="pre">-n</span></code> when the first argument is an integer (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10282">#10282</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">match</span></code> and <code class="docutils literal notranslate"><span class="pre">replace</span></code> have a new <code class="docutils literal notranslate"><span class="pre">--max-matches</span></code> option to return as soon as the specified number of matches have been identified, which can improve performance in scripts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10587">#10587</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">functions</span> <span class="pre">--handlers-type</span> <span class="pre">caller-exit</span></code> once again lists functions defined as <code class="docutils literal notranslate"><span class="pre">function</span> <span class="pre">--on-job-exit</span> <span class="pre">caller</span></code>, rather than them being listed by <code class="docutils literal notranslate"><span class="pre">functions</span> <span class="pre">--handlers-type</span> <span class="pre">process-exit</span></code>.</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">--no-event</span></code> option sets or erases variables without triggering a variable event. This can be useful to change a variable in an event handler (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10480">#10480</a>).</p></li>
<li><p>Commas in command substitution output are no longer used as separators in brace expansion, preventing a surprising expansion in some cases (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5048">#5048</a>).</p></li>
<li><p>Universal variables can now store strings containing invalid UTF-8 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10313">#10313</a>).</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">path</span> <span class="pre">basename</span> <span class="pre">-E</span></code> option that causes it to return the basename (“filename” with the directory prefix removed) with the final extension (if any) also removed. This is a shorter version of <code class="docutils literal notranslate"><span class="pre">path</span> <span class="pre">change-extension</span> <span class="pre">""</span> <span class="pre">(path</span> <span class="pre">basename</span> <span class="pre">$foo)</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10521">#10521</a>).</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">math</span> <span class="pre">--scale-mode</span></code> option to select <code class="docutils literal notranslate"><span class="pre">truncate</span></code>, <code class="docutils literal notranslate"><span class="pre">round</span></code>, <code class="docutils literal notranslate"><span class="pre">floor</span></code>, <code class="docutils literal notranslate"><span class="pre">ceiling</span></code> as you wish; the default value is <code class="docutils literal notranslate"><span class="pre">truncate</span></code>. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9117">#9117</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">random</span></code> is now less strict about its arguments, allowing a start larger or equal to the end. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10879">#10879</a>)</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">function</span> <span class="pre">--argument-names</span></code> now produces an error if a read-only variable name is used, rather than simply ignoring it (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10842">#10842</a>).</p></li>
<li><p>Tilde expansion in braces (that is, <code class="docutils literal notranslate"><span class="pre">{~,}</span></code>) works correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10610">#10610</a>).</p></li>

<h3>Interactive improvements<a class="headerlink" href="#id7" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>Autosuggestions were sometimes not shown after recalling a line from history, which has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10287">#10287</a>).</p></li>
<li><p>Up-arrow search matches -- which are highlighted in reverse colors -- are no longer syntax-highlighted, to fix bad contrast with the search match highlighting.</p></li>
<li><p>Command abbreviations (those with <code class="docutils literal notranslate"><span class="pre">--position</span> <span class="pre">command</span></code> or without a <code class="docutils literal notranslate"><span class="pre">--position</span></code>) now also expand after decorators like <code class="docutils literal notranslate"><span class="pre">command</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10396">#10396</a>).</p></li>
<li><p>Abbreviations now expand after process separators like <code class="docutils literal notranslate"><span class="pre">;</span></code> and <code class="docutils literal notranslate"><span class="pre">|</span></code>. This fixes a regression in version 3.6 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9730">#9730</a>).</p></li>
<li><p>When exporting interactively defined functions (using <code class="docutils literal notranslate"><span class="pre">type</span></code>, <code class="docutils literal notranslate"><span class="pre">functions</span></code> or <code class="docutils literal notranslate"><span class="pre">funcsave</span></code>) the function body is now indented, to match the interactive command line editor (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8603">#8603</a>).</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">x</kbd> (<code class="docutils literal notranslate"><span class="pre">fish_clipboard_copy</span></code>) on multiline commands now includes indentation (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10437">#10437</a>).</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">v</kbd> (<code class="docutils literal notranslate"><span class="pre">fish_clipboard_paste</span></code>) now strips ASCII control characters from the pasted text.
This is consistent with normal keyboard input (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5274">#5274</a>).</p></li>
<li><p>When a command like <code class="docutils literal notranslate"><span class="pre">fg</span> <span class="pre">%2</span></code> fails to find the given job, it no longer behaves as if no job spec was given (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9835">#9835</a>).</p></li>

<h4>New or improved bindings<a class="headerlink" href="#id8" title="Link to this heading">¶</a></h4>
<ul class="simple">
<li><p>When the cursor is on a command that resolves to an executable script, <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">o</kbd> will now open that script in your editor (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10266">#10266</a>).</p></li>
<li><p>During up-arrow history search, <kbd class="kbd docutils literal notranslate">shift</kbd>-<kbd class="kbd docutils literal notranslate">delete</kbd> will delete the current search item and move to the next older item. Previously this was only supported in the history pager.</p></li>
<li><p><kbd class="kbd docutils literal notranslate">shift</kbd>-<kbd class="kbd docutils literal notranslate">delete</kbd> will also remove the currently-displayed autosuggestion from history, and remove it as a suggestion.</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">Z</kbd> (also known as <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">shift</kbd>-<kbd class="kbd docutils literal notranslate">z</kbd>) is now bound to redo.</p></li>
<li><p>Some improvements to the <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">e</kbd> binding which edits the command line in an external editor:</p>
<ul>
<li><p>The editor’s cursor position is copied back to fish. This is currently supported for Vim and Kakoune.</p></li>
<li><p>Cursor position synchronization is only supported for a set of known editors, which are now also detected in aliases which use <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">--wraps</span></code>. For example, use <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">--wraps</span> <span class="pre">my-vim</span> <span class="pre">vim</span></code> to synchronize cursors when <code class="docutils literal notranslate"><span class="pre">EDITOR=my-vim</span></code>.</p></li>
<li><p>Multiline commands are indented before being sent to the editor, which matches how they are displayed in fish.</p></li>
</ul>
</li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">...-path-component</span></code> bindings, like <code class="docutils literal notranslate"><span class="pre">backward-kill-path-component</span></code>, now treat <code class="docutils literal notranslate"><span class="pre">#</span></code> as part of a path component (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10271">#10271</a>).</p></li>
<li><p>Bindings like <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">l</kbd> that print output in between prompts now work correctly with multiline commandlines.</p></li>
<li><p><kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">d</kbd> on an empty command line lists the directory history again. This restores the behavior of version 2.1.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">history-prefix-search-backward</span></code> and <code class="docutils literal notranslate"><span class="pre">-forward</span></code> now maintain the cursor position, instead of moving the cursor to the end of the command line (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10430">#10430</a>).</p></li>
<li><p>The following keys have refined behavior if the terminal supports <a class="reference internal" href="#changelog-4-0-new-bindings"><span class="std std-ref">the new keyboard encodings</span></a>:</p>
<ul>
<li><p><kbd class="kbd docutils literal notranslate">shift</kbd>-<kbd class="kbd docutils literal notranslate">enter</kbd> now inserts a newline instead of executing the command line.</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">backspace</kbd> now deletes the last word instead of only one character (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10741">#10741</a>).</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">delete</kbd> deletes the next word (same as <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">d</kbd>).</p></li>
</ul>
</li>
<li><p>New special input functions:</p>
<ul>
<li><p><code class="docutils literal notranslate"><span class="pre">forward-char-passive</span></code> and <code class="docutils literal notranslate"><span class="pre">backward-char-passive</span></code> are like their non-passive variants but do not accept autosuggestions or move focus in the completion pager (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10398">#10398</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">forward-token</span></code>, <code class="docutils literal notranslate"><span class="pre">backward-token</span></code>, <code class="docutils literal notranslate"><span class="pre">kill-token</span></code>, and <code class="docutils literal notranslate"><span class="pre">backward-kill-token</span></code> are similar to the <code class="docutils literal notranslate"><span class="pre">*-bigword</span></code> variants but for the whole argument token (which includes escaped spaces) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2014">#2014</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">clear-commandline</span></code>, which merely clears the command line, as an alternative to <code class="docutils literal notranslate"><span class="pre">cancel-commandline</span></code> which prints <code class="docutils literal notranslate"><span class="pre">^C</span></code> and a new prompt (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10213">#10213</a>).</p></li>
</ul>
</li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">accept-autosuggestion</span></code> special input function now returns false when there was nothing to accept (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10608">#10608</a>).</p></li>
<li><p>Vi mode has seen some improvements but continues to suffer from the lack of people working on it.</p>
<ul>
<li><p>New default cursor shapes for insert and replace mode.</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">n</kbd> in insert mode accepts autosuggestions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10339">#10339</a>).</p></li>
<li><p>Outside insert mode, the cursor will no longer be placed beyond the last character on the commandline.</p></li>
<li><p>When the cursor is at the end of the commandline, a single <kbd class="kbd docutils literal notranslate">l</kbd> will accept an autosuggestion (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10286">#10286</a>).</p></li>
<li><p>The cursor position after pasting (<kbd class="kbd docutils literal notranslate">p</kbd>) has been corrected.</p></li>
<li><p>Added an additional binding, <kbd class="kbd docutils literal notranslate">_</kbd>, for moving to the beginning of the line (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10720">#10720</a>).</p></li>
<li><p>When the cursor is at the start of a line, escaping from insert mode no longer moves the cursor to the previous line.</p></li>
<li><p>Added bindings for clipboard interaction, like <kbd class="kbd docutils literal notranslate">",</kbd>+<kbd class="kbd docutils literal notranslate">,p</kbd> and <kbd class="kbd docutils literal notranslate">",</kbd>+<kbd class="kbd docutils literal notranslate">,y,y</kbd>.</p></li>
<li><p>Deleting in visual mode now moves the cursor back, matching vi (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10394">#10394</a>).</p></li>
<li><p>The <kbd class="kbd docutils literal notranslate">;</kbd>, <kbd class="kbd docutils literal notranslate">,</kbd>, <kbd class="kbd docutils literal notranslate">v</kbd>, <kbd class="kbd docutils literal notranslate">V</kbd>, <kbd class="kbd docutils literal notranslate">I</kbd>, and <kbd class="kbd docutils literal notranslate">gU</kbd> bindings work in visual mode (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10601">#10601</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10648">#10648</a>).</p></li>
<li><p>Support <kbd class="kbd docutils literal notranslate">%</kbd> motion (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10593">#10593</a>).</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">k</kbd> to remove the contents of the line beyond the cursor in all modes (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10648">#10648</a>).</p></li>
<li><p>Support <cite>ab</cite> and <cite>ib</cite> vi text objects. New input functions are introduced <code class="docutils literal notranslate"><span class="pre">jump-{to,till}-matching-bracket</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1842">#1842</a>).</p></li>
<li><p>The <kbd class="kbd docutils literal notranslate">E</kbd> binding now correctly handles the last character of the word, by jumping to the next word (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9700">#9700</a>).</p></li>

<h4>Completions<a class="headerlink" href="#id9" title="Link to this heading">¶</a></h4>
<ul class="simple">
<li><p>Command-specific tab completions may now offer results whose first character is a period. For example, it is now possible to tab-complete <code class="docutils literal notranslate"><span class="pre">git</span> <span class="pre">add</span></code> for files with leading periods. The default file completions hide these files, unless the token itself has a leading period (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3707">#3707</a>).</p></li>
<li><p>Option completion now uses fuzzy subsequence filtering, just like non-option completion (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/830">#830</a>).
This means that <code class="docutils literal notranslate"><span class="pre">--fb</span></code> may be completed to <code class="docutils literal notranslate"><span class="pre">--foobar</span></code> if there is no better match.</p></li>
<li><p>Completions that insert an entire token now use quotes instead of backslashes to escape special characters (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5433">#5433</a>).</p></li>
<li><p>Normally, file name completions start after the last <code class="docutils literal notranslate"><span class="pre">:</span></code> or <code class="docutils literal notranslate"><span class="pre">=</span></code> in a token.
This helps commands like <code class="docutils literal notranslate"><span class="pre">rsync</span> <span class="pre">--files-from=</span></code>.
This special meaning can now disabled by escaping these separators as <code class="docutils literal notranslate"><span class="pre">\:</span></code> and <code class="docutils literal notranslate"><span class="pre">\=</span></code>.
This matches Bash’s behavior.
Note that this escaping is usually not necessary since the completion engine already tries
to guess whether the separator is actually part of a file name.</p></li>
<li><p>Various new completion scripts and numerous updates to existing ones.</p></li>
<li><p>Completions could hang if the <code class="docutils literal notranslate"><span class="pre">PAGER</span></code> environment variable was sent to certain editors on macOS, FreeBSD and some other platforms. This has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10820">#10820</a>).</p></li>
<li><p>Generated completions are now stored in <code class="docutils literal notranslate"><span class="pre">$XDG_CACHE_HOME/fish</span></code> or <code class="docutils literal notranslate"><span class="pre">~/.cache/fish</span></code> by default (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10369">#10369</a>)</p></li>
<li><p>A regression in fish 3.1, where completing a command line could change it completely, has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10904">#10904</a>).</p></li>

<h4>Improved terminal support<a class="headerlink" href="#id10" title="Link to this heading">¶</a></h4>

Shell integration shortcuts can scroll to the next/previous prompt or show the last command output in a pager.</p></li>

<li><p>Focus reporting in tmux is no longer disabled on the first prompt.</p></li>

<li><p>If it cannot find the terminfo entry given by <span class="target" id="index-15"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">TERM</span></code> environment variable, fish will now use an included <code class="docutils literal notranslate"><span class="pre">xterm-256color</span></code> definition to match the vast majority of current terminal emulators (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10905">#10905</a>).

<section id="rust-packaging">
<span id="id12"></span><h3>For distributors<a class="headerlink" href="#rust-packaging" title="Link to this heading">¶</a></h3>
<p>fish has been ported to Rust. This means a significant change in dependencies, which are listed in the README. In short, Rust 1.70 or greater is required, and a C++ compiler is no longer needed (although a C compiler is still required, for some C glue code and the tests).</p>
<p>CMake remains the recommended build system, because of cargo’s limited support for installing support files. Version 3.5 remains the minimum supported version. The Xcode generator for CMake is not supported any longer (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9924">#9924</a>). CMake builds default to optimized release builds (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10799">#10799</a>).</p>
<p>fish no longer depends on the ncurses library, but still uses a terminfo database. When packaging fish, please add a dependency on the package containing your terminfo database instead of curses.</p>
<p>The <code class="docutils literal notranslate"><span class="pre">test</span></code> target was removed as it can no longer be defined in new CMake versions. Use <code class="docutils literal notranslate"><span class="pre">make</span> <span class="pre">fish_run_tests</span></code>. Any existing test target will not print output if it fails (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/11116">#11116</a>).</p>
<p>The Web-based configuration has been rewritten to use Alpine.js (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9554">#9554</a>).</p>

<h2>fish 3.7.0 (released January 1, 2024)<a class="headerlink" href="#fish-3-7-0-released-january-1-2024" title="Link to this heading">¶</a></h2>
<p>This release of fish includes a number of improvements over fish 3.6.4, detailed below. Although work continues on the porting of fish internals to the Rust programming language, that work is not included in this release. fish 3.7.0 and any future releases in the 3.7 series remain C++ programs.</p>
<section id="id13">
<h3>Notable improvements and fixes<a class="headerlink" href="#id13" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>Improvements to the history pager, including:</p>
<ul>
<li><p>The history pager will now also attempt subsequence matches (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9476">#9476</a>), so you can find a command line like <code class="docutils literal notranslate"><span class="pre">git</span> <span class="pre">log</span> <span class="pre">3.6.1..Integration_3.7.0</span></code> by searching for <code class="docutils literal notranslate"><span class="pre">gitInt</span></code>.</p></li>
<li><p>Opening the history pager will now fill the search field with a search string if you’re already in a search (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10005">#10005</a>). This makes it nicer to search something with <kbd class="kbd docutils literal notranslate">up</kbd> and then later decide to switch to the full pager.</p></li>
<li><p>Closing the history pager with enter will now copy the search text to the commandline if there was no match, so you can continue editing the command you tried to find right away (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9934">#9934</a>).</p></li>
</ul>
</li>
<li><p>Performance improvements for command completions and globbing, where supported by the operating system, especially on slow filesystems such as NFS (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9891">#9891</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9931">#9931</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10032">#10032</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10052">#10052</a>).</p></li>
<li><p>fish can now be configured to wait a specified amount of time for a multi-key sequence to be completed, instead of waiting indefinitely. For example, this makes binding <code class="docutils literal notranslate"><span class="pre">kj</span></code> to switching modes in vi mode possible.
The timeout can be set via the new <span class="target" id="index-16"></span><a class="reference internal" href="language.html#envvar-fish_sequence_key_delay_ms"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_sequence_key_delay_ms</span></code></a> variable (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7401">#7401</a>), and may be set by default in future versions.</p></li>

<h3>Deprecations and removed features<a class="headerlink" href="#id14" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">LS_COLORS</span></code> is no longer set automatically by the <code class="docutils literal notranslate"><span class="pre">ls</span></code> function (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10080">#10080</a>). Users
that set <code class="docutils literal notranslate"><span class="pre">.dircolors</span></code> should manually import it using other means. Typically this would be <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-gx</span> <span class="pre">LS_COLORS</span> <span class="pre">(dircolors</span> <span class="pre">-c</span> <span class="pre">.dircolors</span> <span class="pre">|</span> <span class="pre">string</span> <span class="pre">split</span> <span class="pre">'</span> <span class="pre">')[3]</span></code></p></li>

<h3>Scripting improvements<a class="headerlink" href="#id15" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>Running <code class="docutils literal notranslate"><span class="pre">exit</span></code> with a negative number no longer crashes fish (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9659">#9659</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--command</span></code> will now return a non-zero status if parsing failed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9888">#9888</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">jobs</span></code> builtin will now escape the commands it prints (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9808">#9808</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">repeat</span></code> no longer overflows if the count is a multiple of the chunk size (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9900">#9900</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">builtin</span></code> builtin will now properly error out with invalid arguments instead of doing nothing and returning true (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9942">#9942</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">command</span> <span class="pre">time</span></code> in a pipeline is allowed again, as is <code class="docutils literal notranslate"><span class="pre">command</span> <span class="pre">and</span></code> and <code class="docutils literal notranslate"><span class="pre">command</span> <span class="pre">or</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9985">#9985</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">exec</span></code> will now also apply variable overrides, so <code class="docutils literal notranslate"><span class="pre">FOO=bar</span> <span class="pre">exec</span></code> will now set <code class="docutils literal notranslate"><span class="pre">$FOO</span></code> correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9995">#9995</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">umask</span></code> will now handle empty symbolic modes correctly, like <code class="docutils literal notranslate"><span class="pre">umask</span> <span class="pre">u=,g=rwx,o=</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10177">#10177</a>).</p></li>
<li><p>Improved error messages for errors occurring in command substitutions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10054">#10054</a>).</p></li>

<h3>Interactive improvements<a class="headerlink" href="#id16" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">read</span></code> no longer enables bracketed paste so it doesn’t stay enabled in combined commandlines like <code class="docutils literal notranslate"><span class="pre">mysql</span> <span class="pre">-p(read</span> <span class="pre">--silent)</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8285">#8285</a>).</p></li>
<li><p>Vi mode now uses <span class="target" id="index-17"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_cursor_external</span></code> to set the cursor shape for external commands (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4656">#4656</a>).</p></li>
<li><p>Opening the history search in vi mode switches to insert mode correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10141">#10141</a>).</p></li>
<li><p>Vi mode cursor shaping is now enabled in iTerm2 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9698">#9698</a>).</p></li>
<li><p>Completing commands as root includes commands not owned by root, fixing a regression introduced in fish 3.2.0 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9699">#9699</a>).</p></li>
<li><p>Selection uses <code class="docutils literal notranslate"><span class="pre">fish_color_selection</span></code> for the foreground and background colors, as intended, rather than just the background (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9717">#9717</a>).</p></li>
<li><p>The completion pager will no longer sometimes skip the last entry when moving through a long list (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9833">#9833</a>).</p></li>
<li><p>The interactive <code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">delete</span></code> interface now allows specifying index ranges like “1..5” (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9736">#9736</a>), and <code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">delete</span> <span class="pre">--exact</span></code> now properly saves the history (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10066">#10066</a>).</p></li>
<li><p>Command completion will now call the stock <code class="docutils literal notranslate"><span class="pre">manpath</span></code> on macOS, instead of a potential Homebrew version. This prevents awkward error messages (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9817">#9817</a>).</p></li>
<li><p>the <code class="docutils literal notranslate"><span class="pre">redo</span></code> special input function restores the pre-undo cursor position.</p></li>
<li><p>A new bind function <code class="docutils literal notranslate"><span class="pre">history-pager-delete</span></code>, bound to <kbd class="kbd docutils literal notranslate">shift</kbd>-<kbd class="kbd docutils literal notranslate">delete</kbd> by default, will delete the currently-selected history pager item from history (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9454">#9454</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_key_reader</span></code> will now use printable characters as-is, so pressing “ö” no longer leads to it telling you to bind <code class="docutils literal notranslate"><span class="pre">\u00F6</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9986">#9986</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">open</span></code> can be used to launch terminal programs again, as an <code class="docutils literal notranslate"><span class="pre">xdg-open</span></code> bug has been fixed and a workaround has been removed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10045">#10045</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">repaint-mode</span></code> binding will now only move the cursor if there is repainting to be done. This fixes <kbd class="kbd docutils literal notranslate">alt</kbd> combination bindings in vi mode (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7910">#7910</a>).</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">clear-screen</span></code> bind function is used for <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">l</kbd> by default. This clears the screen and repaints the existing prompt at first,
so it eliminates visible flicker unless the terminal is very slow (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10044">#10044</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">alias</span></code> convenience function has better support for commands with unusual characters, like <code class="docutils literal notranslate"><span class="pre">+</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8720">#8720</a>).</p></li>
<li><p>A longstanding issue where items in the pager would sometimes display without proper formatting has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9617">#9617</a>).</p></li>
<li><p>The <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">l</kbd> binding, which lists the directory of the token under the cursor, correctly expands tilde (<code class="docutils literal notranslate"><span class="pre">~</span></code>) to the home directory (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9954">#9954</a>).</p></li>
<li><p>Various fish utilities that use an external pager will now try a selection of common pagers if the <span class="target" id="index-18"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">PAGER</span></code> environment variable is not set, or write the output to the screen without a pager if there is not one available (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/10074">#10074</a>).</p></li>
<li><p>Command-specific tab completions may now offer results whose first character is a period. For example, it is now possible to tab-complete <code class="docutils literal notranslate"><span class="pre">git</span> <span class="pre">add</span></code> for files with leading periods. The default file completions hide these files, unless the token itself has a leading period (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3707">#3707</a>).</p></li>

<li><p>The Dracula theme has now been synced with upstream (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9807">#9807</a>); use <code class="docutils literal notranslate"><span class="pre">fish_config</span></code> to re-apply it to pick up the changes.</p></li>

<h2>fish 3.6.2 (released December 4, 2023)<a class="headerlink" href="#fish-3-6-2-released-december-4-2023" title="Link to this heading">¶</a></h2>
<p>This release of fish contains a security fix for CVE-2023-49284, a minor security problem identified
in fish 3.6.1 and previous versions (thought to affect all released versions of fish).</p>
<p>fish uses certain Unicode non-characters internally for marking wildcards and expansions. It
incorrectly allowed these markers to be read on command substitution output, rather than
transforming them into a safe internal representation.</p>
<p>For example, <code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">\UFDD2HOME</span></code> has the same output as <code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">$HOME</span></code>.</p>
<p>While this may cause unexpected behavior with direct input, this may become a minor security problem
if the output is being fed from an external program into a command substitution where this output
may not be expected.</p>

<li><p>The <code class="docutils literal notranslate"><span class="pre">\x</span></code> and <code class="docutils literal notranslate"><span class="pre">\X</span></code> escape syntax is now equivalent. <code class="docutils literal notranslate"><span class="pre">\xAB</span></code> previously behaved the same as <code class="docutils literal notranslate"><span class="pre">\XAB</span></code>, except that it would error if the value “AB” was larger than “7f” (127 in decimal, the highest ASCII value) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9247">#9247</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9245">#9245</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1352">#1352</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_git_prompt</span></code> will now only turn on features if the appropriate variable has been set to a true value (of “1”, “yes” or “true”) instead of just checking if it is defined. This allows specifically turning features <em>off</em> without having to erase variables, such as via universal variables. If you have defined a variable to a different value and expect it to count as true, you need to change it (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9274">#9274</a>).
For example, <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-g</span> <span class="pre">__fish_git_prompt_show_informative_status</span> <span class="pre">0</span></code> previously would have enabled informative status (because any value would have done so), but now it turns it off.</p></li>
<li><p>Abbreviations are no longer stored in universal variables. Existing universal abbreviations are still imported, but new abbreviations should be added to <code class="docutils literal notranslate"><span class="pre">config.fish</span></code>.</p></li>
<li><p>The short option <code class="docutils literal notranslate"><span class="pre">-r</span></code> for abbreviations has changed from <code class="docutils literal notranslate"><span class="pre">rename</span></code> to <code class="docutils literal notranslate"><span class="pre">regex</span></code>, for consistency with <code class="docutils literal notranslate"><span class="pre">string</span></code>.</p></li>

<h3>Interactive improvements<a class="headerlink" href="#id31" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>If the terminal definition for <span class="target" id="index-20"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">TERM</span></code> can’t be found, fish now tries using the “xterm-256color” and “xterm” definitions before “ansi” and “dumb”. As the majority of terminal emulators in common use are now more or less xterm-compatible (often even explicitly claiming the xterm-256color entry), this should often result in a fully or almost fully usable terminal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9026">#9026</a>).</p></li>
<li><p>A new variable, <span class="target" id="index-21"></span><a class="reference internal" href="language.html#envvar-fish_cursor_selection_mode"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_cursor_selection_mode</span></code></a>, can be used to configure whether the command line selection includes the character under the cursor (<code class="docutils literal notranslate"><span class="pre">inclusive</span></code>) or not (<code class="docutils literal notranslate"><span class="pre">exclusive</span></code>). The new default is <code class="docutils literal notranslate"><span class="pre">exclusive</span></code>; use <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">fish_cursor_selection_mode</span> <span class="pre">inclusive</span></code> to get the previous behavior back (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7762">#7762</a>).</p></li>
<li><p>fish’s completion pager now fills half the terminal on first tab press instead of only 4 rows, which should make results visible more often and save key presses, without constantly snapping fish to the top of the terminal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9105">#9105</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2698">#2698</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">complete-and-search</span></code> binding, used with <kbd class="kbd docutils literal notranslate">shift</kbd>-<kbd class="kbd docutils literal notranslate">tab</kbd> by default, selects the first item in the results immediately (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9080">#9080</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">bind</span></code> output is now syntax-highlighted when used interactively.</p></li>
<li><p><kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">h</kbd> (the default <code class="docutils literal notranslate"><span class="pre">__fish_man_page</span></code> binding) does a better job of showing the manual page of the command under cursor (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9020">#9020</a>).</p></li>
<li><p>If <span class="target" id="index-22"></span><a class="reference internal" href="interactive.html#envvar-fish_color_valid_path"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_color_valid_path</span></code></a> contains an actual color instead of just modifiers, those will be used for valid paths even if the underlying color isn’t “normal” (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9159">#9159</a>).</p></li>
<li><p>The key combination for the QUIT terminal sequence, often <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">\</kbd> (<code class="docutils literal notranslate"><span class="pre">\x1c</span></code>), can now be used as a binding (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9234">#9234</a>).</p></li>
<li><p>fish’s vi mode uses normal xterm-style sequences to signal cursor change, instead of using the iTerm’s proprietary escape sequences. This allows for a blinking cursor and makes it work in complicated scenarios with nested terminals. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3741">#3741</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9172">#9172</a>)</p></li>
<li><p>When running fish on a remote system (such as inside SSH or a container), <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">x</kbd> now copies to the local client system’s clipboard if the terminal supports OSC 52.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">commandline</span></code> gained two new options, <code class="docutils literal notranslate"><span class="pre">--selection-start</span></code> and <code class="docutils literal notranslate"><span class="pre">--selection-end</span></code>, to set the start/end of the current selection (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9197">#9197</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9215">#9215</a>).</p></li>
<li><p>fish’s builtins now handle keyboard interrupts (<kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">c</kbd>) correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9266">#9266</a>).</p></li>

<li><p><code class="docutils literal notranslate"><span class="pre">status</span> <span class="pre">fish-path</span></code> on Linux-based platforms could print the path with a “ (deleted)” suffix (such as <code class="docutils literal notranslate"><span class="pre">/usr/bin/fish</span> <span class="pre">(deleted)</span></code>), which is now removed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9019">#9019</a>).</p></li>
<li><p>Cancelling an initial command (from fish’s <code class="docutils literal notranslate"><span class="pre">--init-command</span></code> option) with <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">c</kbd> no longer prevents configuration scripts from running (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9024">#9024</a>).</p></li>
<li><p>The job summary contained extra blank lines if the prompt used multiple lines, which is now fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9044">#9044</a>).</p></li>

<section id="id37">
<h3>Deprecations and removed features<a class="headerlink" href="#id37" title="Link to this heading">¶</a></h3>
<ul>
<li><p>The <code class="docutils literal notranslate"><span class="pre">stderr-nocaret</span></code> feature flag, introduced in fish 3.0 and enabled by default in fish 3.1, has been made read-only.
That means it is no longer possible to disable it, and code supporting the <code class="docutils literal notranslate"><span class="pre">^</span></code> redirection has been removed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8857">#8857</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8865">#8865</a>).</p>
<p>To recap: fish used to support <code class="docutils literal notranslate"><span class="pre">^</span></code> to redirect stderr, so you could use commands like:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">test</span><span class="w"> </span><span class="s2">"</span><span class="o">$foo</span><span class="s2">"</span><span class="w"> </span><span class="no">-gt</span><span class="w"> </span><span class="no">8</span><span class="w"> </span><span class="no">^/dev/null</span>
</pre></div>
</div>
<p>to ignore error messages. This made the <code class="docutils literal notranslate"><span class="pre">^</span></code> symbol require escaping and quoting, and was a bit of a weird shortcut considering <code class="docutils literal notranslate"><span class="pre">2></span></code> already worked, which is only one character longer.</p>
<p>So the above can simply become:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">test</span><span class="w"> </span><span class="s2">"</span><span class="o">$foo</span><span class="s2">"</span><span class="w"> </span><span class="no">-gt</span><span class="w"> </span><span class="no">8</span><span class="w"> </span><span class="p">2>/dev/null</span>
</pre></div>
</div>
</li>
<li><p>The following feature flags have been enabled by default:</p>
<ul>
<li><p><code class="docutils literal notranslate"><span class="pre">regex-easyesc</span></code>, which makes <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">replace</span> <span class="pre">-r</span></code> not do a superfluous round of unescaping in the replacement expression.
That means e.g. to escape any “a” or “b” in an argument you can use <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">replace</span> <span class="pre">-ra</span> <span class="pre">'([ab])'</span> <span class="pre">'\\\\$1'</span> <span class="pre">foobar</span></code> instead of needing 8 backslashes.</p>
<p>This only affects the <em>replacement</em> expression, not the <em>match</em> expression (the <code class="docutils literal notranslate"><span class="pre">'([ab])'</span></code> part in the example).
A survey of plugins on GitHub did not turn up any affected code, so we do not expect this to affect many users.</p>
<p>This flag was introduced in fish 3.1.</p>
</li>
<li><p><code class="docutils literal notranslate"><span class="pre">ampersand-nobg-in-token</span></code>, which means that <code class="docutils literal notranslate"><span class="pre">&</span></code> will not create a background job if it occurs in the middle of a word. For example, <code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">foo&bar</span></code> will print “foo&bar” instead of running <code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">foo</span></code> in the background and then starting <code class="docutils literal notranslate"><span class="pre">bar</span></code> as a second job.</p>
<p>Reformatting with <code class="docutils literal notranslate"><span class="pre">fish_indent</span></code> would already introduce spaces, turning <code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">foo&bar</span></code> into <code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">foo</span> <span class="pre">&</span> <span class="pre">bar</span></code>.</p>
<p>This flag was introduced in fish 3.4.</p>
</li>
</ul>
<p>To turn off these flags, add <code class="docutils literal notranslate"><span class="pre">no-regex-easyesc</span></code> or <code class="docutils literal notranslate"><span class="pre">no-ampersand-nobg-in-token</span></code> to <span class="target" id="index-24"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_features</span></code> and restart fish:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">set</span><span class="w"> </span><span class="no">-Ua</span><span class="w"> </span><span class="no">fish_features</span><span class="w"> </span><span class="no">no-regex-easyesc</span>
</pre></div>
</div>
<p>Like <code class="docutils literal notranslate"><span class="pre">stderr-nocaret</span></code>, they will eventually be made read-only.</p>
</li>
<li><p>Most <code class="docutils literal notranslate"><span class="pre">string</span></code> subcommands no longer append a newline to their input if the input didn’t have one (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8473">#8473</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3847">#3847</a>)</p></li>
<li><p>Fish’s escape sequence removal (like for <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">length</span> <span class="pre">--visible</span></code> or to figure out how wide the prompt is) no longer has special support for non-standard color sequences like from Data General terminals, e.g. the Data General Dasher D220 from 1984. This removes a bunch of work in the common case, allowing <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">length</span> <span class="pre">--visible</span></code> to be much faster with unknown escape sequences. We don’t expect anyone to have ever used fish with such a terminal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8769">#8769</a>).</p></li>
<li><p>Code to upgrade universal variables from fish before 3.0 has been removed. Users who upgrade directly from fish versions 2.7.1 or before will have to set their universal variables & abbreviations again. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8781">#8781</a>)</p></li>
<li><p>The meaning of an empty color variable has changed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8793">#8793</a>). Previously, when a variable was set but empty, it would be interpreted as the “normal” color. Now, empty color variables cause the same effect as unset variables - the general highlighting variable for that type is used instead. For example:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">set</span><span class="w"> </span><span class="no">-g</span><span class="w"> </span><span class="no">fish_color_command</span><span class="w"> </span><span class="no">blue</span>
<span class="nf">set</span><span class="w"> </span><span class="no">-g</span><span class="w"> </span><span class="no">fish_color_keyword</span>
</pre></div>
</div>
<p>would previously make keywords “normal” (usually white in a dark terminal). Now it’ll make them blue. To achieve the previous behavior, use the normal color explicitly: <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-g</span> <span class="pre">fish_color_keyword</span> <span class="pre">normal</span></code>.</p>
<p>This makes it easier to make self-contained color schemes that don’t accidentally use color that was set before.
<code class="docutils literal notranslate"><span class="pre">fish_config</span></code> has been adjusted to set known color variables that a theme doesn’t explicitly set to empty.</p>
</li>
<li><p><code class="docutils literal notranslate"><span class="pre">eval</span></code> is now a reserved keyword, so it can’t be used as a function name. This follows <code class="docutils literal notranslate"><span class="pre">set</span></code> and <code class="docutils literal notranslate"><span class="pre">read</span></code>, and is necessary because it can’t be cleanly shadowed by a function - at the very least <code class="docutils literal notranslate"><span class="pre">eval</span> <span class="pre">set</span> <span class="pre">-l</span> <span class="pre">argv</span> <span class="pre">foo</span></code> breaks. Fish will ignore autoload files for it, so left over <code class="docutils literal notranslate"><span class="pre">eval.fish</span></code> from previous fish versions won’t be loaded.</p></li>
<li><p>The git prompt in informative mode now defaults to skipping counting untracked files, as this was extremely slow. To turn it on, set <span class="target" id="index-25"></span><code class="xref std std-envvar docutils literal notranslate"><span class="pre">__fish_git_prompt_showuntrackedfiles</span></code> or set the git config value “bash.showuntrackedfiles” to <code class="docutils literal notranslate"><span class="pre">true</span></code> explicitly (which can be done for individual repositories). The “informative+vcs” sample prompt already skipped display of untracked files, but didn’t do so in a way that skipped the computation, so it should be quite a bit faster in many cases (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8980">#8980</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">__terlar_git_prompt</span></code> function, used by the “Terlar” sample prompt, has been rebuilt as a configuration of the normal <code class="docutils literal notranslate"><span class="pre">fish_git_prompt</span></code> to ease maintenance, improve performance and add features (like reading per-repo git configuration). Some slight changes remain; users who absolutely must have the same behavior are encouraged to copy the old function (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/9011">#9011</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7918">#7918</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8979">#8979</a>).</p></li>

<h3>Notable improvements and fixes<a class="headerlink" href="#id45" title="Link to this heading">¶</a></h3>
<ul>
<li><p>fish’s command substitution syntax has been extended: <code class="docutils literal notranslate"><span class="pre">$(cmd)</span></code> now has the same meaning as <code class="docutils literal notranslate"><span class="pre">(cmd)</span></code> but it can be used inside double quotes, to prevent line splitting of the results (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/159">#159</a>):</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">foo</span><span class="w"> </span><span class="o">(</span><span class="nf">bar</span><span class="w"> </span><span class="p">|</span><span class="w"> </span><span class="nf">string</span><span class="w"> </span><span class="no">collect</span><span class="o">)</span>
<span class="c"># can now be written as</span>
<span class="nf">foo</span><span class="w"> </span><span class="s2">"</span><span class="o">$(</span><span class="nf">bar</span><span class="o">)</span><span class="s2">"</span>
<span class="c"># and</span>
<span class="nf">foo</span><span class="w"> </span><span class="o">(</span><span class="nf">bar</span><span class="o">)</span>
<span class="c"># can now be written as</span>
<span class="nf">foo</span><span class="w"> </span><span class="o">$(</span><span class="nf">bar</span><span class="o">)</span>
<span class="c"># this will still split on newlines only.</span>
</pre></div>
</div>
</li>
<li><p>Complementing the <code class="docutils literal notranslate"><span class="pre">prompt</span></code> command in 3.3.0, <code class="docutils literal notranslate"><span class="pre">fish_config</span></code> gained a <code class="docutils literal notranslate"><span class="pre">theme</span></code> subcommand to show and pick from the sample themes (meaning color schemes) directly in the terminal, instead of having to open a Web browser. For example <code class="docutils literal notranslate"><span class="pre">fish_config</span> <span class="pre">theme</span> <span class="pre">choose</span> <span class="pre">Nord</span></code> loads the Nord theme in the current session (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8132">#8132</a>). The current theme can be saved with <code class="docutils literal notranslate"><span class="pre">fish_config</span> <span class="pre">theme</span> <span class="pre">dump</span></code>, and custom themes can be added by saving them in <code class="docutils literal notranslate"><span class="pre">~/.config/fish/themes/</span></code>.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set</span></code> and <code class="docutils literal notranslate"><span class="pre">read</span></code> learned a new option, <code class="docutils literal notranslate"><span class="pre">--function</span></code>, to set a variable in the function’s top scope. This should be a more familiar way of scoping variables and avoids issues with <code class="docutils literal notranslate"><span class="pre">--local</span></code>, which is actually block-scoped (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/565">#565</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8145">#8145</a>):</p>

<span class="nf">end</span>
</pre></div>
</div>
</li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">pad</span></code> now excludes escape sequences like colors that fish knows about, and a new <code class="docutils literal notranslate"><span class="pre">--visible</span></code> flag to <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">length</span></code> makes it use that kind of visible width. This is useful to get the number of terminal cells an already colored string would occupy, like in a prompt. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8182">#8182</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7784">#7784</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4012">#4012</a>):</p>

<span class="go">3</span>
</pre></div>
</div>
</li>
<li><p>Performance improvements to globbing, especially on systems using glibc. In some cases (large directories with files with many numbers in the names) this almost halves the time taken to expand the glob.</p></li>
<li><p>Autosuggestions can now be turned off by setting <code class="docutils literal notranslate"><span class="pre">$fish_autosuggestion_enabled</span></code> to 0, and (almost) all highlighting can be turned off by choosing the new “None” theme. The exception is necessary colors, like those which distinguish autosuggestions from the actual command line. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8376">#8376</a>)</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_git_prompt</span></code> function, which is included in the default prompts, now overrides <code class="docutils literal notranslate"><span class="pre">git</span></code> to avoid running commands set by per-repository configuration. This avoids a potential security issue in some circumstances, and has been assigned CVE-2022-20001 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8589">#8589</a>).</p></li>

<h3>Deprecations and removed features<a class="headerlink" href="#id46" title="Link to this heading">¶</a></h3>
<ul>
<li><p>A new feature flag, <code class="docutils literal notranslate"><span class="pre">ampersand-nobg-in-token</span></code> makes <code class="docutils literal notranslate"><span class="pre">&</span></code> only act as background operator if followed by a separator. In combination with <code class="docutils literal notranslate"><span class="pre">qmark-noglob</span></code>, this allows entering most URLs at the command line without quoting or escaping (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7991">#7991</a>). For example:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="gp">> </span><span class="nf">echo</span><span class="w"> </span><span class="no">foo&bar</span><span class="w"> </span><span class="c"># will print "foo&bar", instead of running "echo foo" in the background and executing "bar"</span>
<span class="gp">> </span><span class="nf">echo</span><span class="w"> </span><span class="no">foo</span><span class="w"> </span><span class="p">&</span><span class="w"> </span><span class="nf">bar</span><span class="w"> </span><span class="c"># will still run "echo foo" in the background and then run "bar"</span>
<span class="go"># with both ampersand-nobg-in-token and qmark-noglob, this argument has no special characters anymore</span>
<span class="gp">> </span><span class="nf">open</span><span class="w"> </span><span class="no">https://www.youtube.com/watch?v=dQw4w9WgXcQ&feature=youtu.be</span>
</pre></div>
</div>
<p>As a reminder, feature flags can be set on startup with <code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--features</span> <span class="pre">ampersand-nobg-in-token,qmark-noglob</span></code> or with a universal variable called <code class="docutils literal notranslate"><span class="pre">fish_features</span></code>:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="gp">> </span><span class="nf">set</span><span class="w"> </span><span class="no">-Ua</span><span class="w"> </span><span class="no">fish_features</span><span class="w"> </span><span class="no">ampersand-nobg-in-token</span>
</pre></div>
</div>
</li>
<li><p><code class="docutils literal notranslate"><span class="pre">$status</span></code> is now forbidden as a command, to prevent a surprisingly common error among new users: Running <code class="docutils literal notranslate"><span class="pre">if</span> <span class="pre">$status</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8171">#8171</a>). This applies <em>only</em> to <code class="docutils literal notranslate"><span class="pre">$status</span></code>, other variables are still allowed.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">--query</span></code> now returns an exit status of 255 if given no variable names. This means <code class="docutils literal notranslate"><span class="pre">if</span> <span class="pre">set</span> <span class="pre">-q</span> <span class="pre">$foo</span></code> will not enter the if-block if <code class="docutils literal notranslate"><span class="pre">$foo</span></code> is empty or unset. To restore the previous behavior, use <code class="docutils literal notranslate"><span class="pre">if</span> <span class="pre">not</span> <span class="pre">set</span> <span class="pre">-q</span> <span class="pre">foo;</span> <span class="pre">or</span> <span class="pre">set</span> <span class="pre">-q</span> <span class="pre">$foo</span></code> - but this is unlikely to be desirable (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8214">#8214</a>).</p></li>

<h3>Scripting improvements<a class="headerlink" href="#id47" title="Link to this heading">¶</a></h3>
<ul>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">collect</span></code> supports a new <code class="docutils literal notranslate"><span class="pre">--allow-empty</span></code> option, which will output one empty argument in a command substitution that has no output (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8054">#8054</a>). This allows commands like <code class="docutils literal notranslate"><span class="pre">test</span> <span class="pre">-n</span> <span class="pre">(echo</span> <span class="pre">-n</span> <span class="pre">|</span> <span class="pre">string</span> <span class="pre">collect</span> <span class="pre">--allow-empty)</span></code> to work more reliably. Note this can also be written as <code class="docutils literal notranslate"><span class="pre">test</span> <span class="pre">-n</span> <span class="pre">"$(echo</span> <span class="pre">-n)"</span></code> (see above).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">match</span></code> gained a <code class="docutils literal notranslate"><span class="pre">--groups-only</span></code> option, which makes it only output capturing groups, excluding the full match. This allows <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">match</span></code> to do simple transformations (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6056">#6056</a>):</p>

</div>
</li>
<li><p><code class="docutils literal notranslate"><span class="pre">$fish_user_paths</span></code> is now automatically deduplicated to fix a common user error of appending to it in config.fish when it is universal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8117">#8117</a>). <a class="reference internal" href="cmds/fish_add_path.html"><span class="doc">fish_add_path</span></a> remains the recommended way to add to $PATH.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">return</span></code> can now be used outside functions. In scripts, it does the same thing as <code class="docutils literal notranslate"><span class="pre">exit</span></code>. In interactive mode,it sets <code class="docutils literal notranslate"><span class="pre">$status</span></code> without exiting (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8148">#8148</a>).</p></li>
<li><p>An oversight prevented all syntax checks from running on commands given to <code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">-c</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8171">#8171</a>). This includes checks such as <code class="docutils literal notranslate"><span class="pre">exec</span></code> not being allowed in a pipeline, and <code class="docutils literal notranslate"><span class="pre">$$</span></code> not being a valid variable. Generally, another error was generated anyway.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_indent</span></code> now correctly reformats tokens that end with a backslash followed by a newline (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8197">#8197</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">commandline</span></code> gained an <code class="docutils literal notranslate"><span class="pre">--is-valid</span></code> option to check if the command line is syntactically valid and complete. This allows basic implementation of transient prompts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8142">#8142</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">commandline</span></code> gained a <code class="docutils literal notranslate"><span class="pre">--paging-full-mode</span></code> option to check if the pager is showing all the possible lines (no “7 more rows” message) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8485">#8485</a>).</p></li>
<li><p>List expansion correctly reports an error when used with all zero indexes (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8213">#8213</a>).</p></li>
<li><p>Running <code class="docutils literal notranslate"><span class="pre">fish</span></code> with a directory instead of a script as argument (eg <code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">.</span></code>) no longer leads to an infinite loop. Instead it errors out immediately (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8258">#8258</a>)</p></li>
<li><p>Some error messages occurring after fork, like “text file busy” have been replaced by bespoke error messages for fish (like “File is currently open for writing”). This also restores error messages with current glibc versions that removed sys_errlist (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8234">#8234</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4183">#4183</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">realpath</span></code> builtin now also squashes leading slashes with the <code class="docutils literal notranslate"><span class="pre">--no-symlinks</span></code> option (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8281">#8281</a>).</p></li>
<li><p>When trying to <code class="docutils literal notranslate"><span class="pre">cd</span></code> to a dangling (broken) symbolic link, fish will print an error noting that the target is a broken link (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8264">#8264</a>).</p></li>
<li><p>On MacOS terminals that are not granted permissions to access a folder, <code class="docutils literal notranslate"><span class="pre">cd</span></code> would print a spurious “rotten symlink” error, which has been corrected to “permission denied” (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8264">#8264</a>).</p></li>
<li><p>Since fish 3.0, <code class="docutils literal notranslate"><span class="pre">for</span></code> loops would trigger a variable handler function before the loop was entered. As the variable had not actually changed or been set, this was a spurious event and has been removed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8384">#8384</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">math</span></code> now correctly prints negative values and values larger than <code class="docutils literal notranslate"><span class="pre">2**31</span></code> when in hex or octal bases (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8417">#8417</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">dirs</span></code> always produces an exit status of 0, instead of sometimes returning 1 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8211">#8211</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">cd</span> <span class="pre">""</span></code> no longer crashes fish (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8147">#8147</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">--query</span></code> can now query whether a variable is a path variable via <code class="docutils literal notranslate"><span class="pre">--path</span></code> or <code class="docutils literal notranslate"><span class="pre">--unpath</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8494">#8494</a>).</p></li>
<li><p>Tilde characters (<code class="docutils literal notranslate"><span class="pre">~</span></code>) produced by custom completions are no longer escaped when applied to the command line, making it easier to use the output of a recursive <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">-C</span></code> in completion scripts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4570">#4570</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">--show</span></code> reports when a variable is read-only (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8179">#8179</a>).</p></li>
<li><p>Erasing <code class="docutils literal notranslate"><span class="pre">$fish_emoji_width</span></code> will reset fish to the default guessed emoji width (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8274">#8274</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">la</span></code> function no longer lists entries for “.” and “..”, matching other systems defaults (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8519">#8519</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">abbr</span> <span class="pre">-q</span></code> returns the correct exit status when given multiple abbreviation names as arguments (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8431">#8431</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">command</span> <span class="pre">-v</span></code> returns an exit status of 127 instead of 1 if no command was found (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8547">#8547</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">argparse</span></code> with <code class="docutils literal notranslate"><span class="pre">--ignore-unknown</span></code> no longer breaks with multiple unknown options in a short option group (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8637">#8637</a>).</p></li>
<li><p>Comments inside command substitutions or brackets now correctly ignore parentheses, quotes, and brackets (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7866">#7866</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8022">#8022</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8695">#8695</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">-C</span></code> supports a new <code class="docutils literal notranslate"><span class="pre">--escape</span></code> option, which turns on escaping in returned completion strings (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3469">#3469</a>).</p></li>
<li><p>Invalid byte or unicode escapes like <code class="docutils literal notranslate"><span class="pre">\Utest</span></code> or <code class="docutils literal notranslate"><span class="pre">\xNotHex</span></code> are now a tokenizer error instead of causing the token to be truncated (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8545">#8545</a>).</p></li>

<h3>Interactive improvements<a class="headerlink" href="#id48" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>Vi mode cursors are now set properly after <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">c</kbd> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8125">#8125</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">funced</span></code> will try to edit the whole file containing a function definition, if there is one (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/391">#391</a>).</p></li>
<li><p>Running a command line consisting of just spaces now deletes an ephemeral (starting with space) history item again (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8232">#8232</a>).</p></li>
<li><p>Command substitutions no longer respect job control, instead running inside fish’s own process group (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8172">#8172</a>). This more closely matches other shells, and improves <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">c</kbd> reliability inside a command substitution.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">history</span></code> and <code class="docutils literal notranslate"><span class="pre">__fish_print_help</span></code> now properly support <code class="docutils literal notranslate"><span class="pre">less</span></code> before version 530, including the version that ships with macOS. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8157">#8157</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">help</span></code> now knows which section is in which document again (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8245">#8245</a>).</p></li>
<li><p>fish’s highlighter will now color options (starting with <code class="docutils literal notranslate"><span class="pre">-</span></code> or <code class="docutils literal notranslate"><span class="pre">--</span></code>) with the color given in the new $fish_color_option, up to the first <code class="docutils literal notranslate"><span class="pre">--</span></code>. It falls back on $fish_color_param, so nothing changes for existing setups (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8292">#8292</a>).</p></li>
<li><p>When executing a command, abbreviations are no longer expanded when the cursor is separated from the command by spaces, making it easier to suppress abbreviation expansion of commands without arguments. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8423">#8423</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_key_reader</span></code>’s output was simplified. By default, it now only prints a bind statement. The previous per-character timing information can be seen with a new <code class="docutils literal notranslate"><span class="pre">--verbose</span></code> switch (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8467">#8467</a>).</p></li>
<li><p>Custom completions are now also loaded for commands that contain tildes or variables like <code class="docutils literal notranslate"><span class="pre">~/bin/fish</span></code> or <code class="docutils literal notranslate"><span class="pre">$PWD/fish</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8442">#8442</a>).</p></li>
<li><p>Command lines spanning multiple lines will not be overwritten by the completion pager when it fills the entire terminal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8509">#8509</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8405">#8405</a>).</p></li>
<li><p>When redrawing a multiline prompt, the old prompt is now properly cleared (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8163">#8163</a>).</p></li>
<li><p>Interactive completion would occasionally ignore the last word on the command line due to a race condition. This has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8175">#8175</a>).</p></li>
<li><p>Propagation of universal variables from a fish process that is closing is faster (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8209">#8209</a>).</p></li>
<li><p>The command line is drawn in the correct place if the prompt ends with a newline (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8298">#8298</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">history</span></code> learned a new subcommand <code class="docutils literal notranslate"><span class="pre">clear-session</span></code> to erase all history from the current session (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5791">#5791</a>).</p></li>
<li><p>Pressing <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">c</kbd> in <code class="docutils literal notranslate"><span class="pre">fish_key_reader</span></code> will no longer print the incorrect “Press [ctrl-C] again to exit” message (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8510">#8510</a>).</p></li>
<li><p>The default command-not-found handler for Fedora/PackageKit now passes the whole command line, allowing for functionality such as running the suggested command directly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8579">#8579</a>).</p></li>
<li><p>When looking for locale information, the Debian configuration is now used when available (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8557">#8557</a>).</p></li>
<li><p>Pasting text containing quotes from the clipboard trims spaces more appropriately (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8550">#8550</a>).</p></li>
<li><p>The clipboard bindings ignore X-based clipboard programs if the <code class="docutils literal notranslate"><span class="pre">DISPLAY</span></code> environment variable is not set, which helps prefer the Windows clipboard when it is available (such as on WSL).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">funcsave</span></code> will remove a saved copy of a function that has been erased with <code class="docutils literal notranslate"><span class="pre">functions</span> <span class="pre">--erase</span></code>.</p></li>
<li><p>The Web-based configuration tool gained a number of improvements, including the ability to set pager colors.</p></li>
<li><p>The default <code class="docutils literal notranslate"><span class="pre">fish_title</span></code> prints a shorter title with shortened $PWD and no more redundant “fish” (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8641">#8641</a>).</p></li>
<li><p>Holding down an arrow key won’t freeze the terminal with long periods of flashing (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8610">#8610</a>).</p></li>
<li><p>Multi-char bindings are no longer interrupted if a signal handler enqueues an event. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8628">#8628</a>).</p></li>

<p>This release of fish fixes the following problems identified in fish 3.3.0:</p>
<ul class="simple">
<li><p>The prompt and command line are redrawn correctly in response to universal variable changes (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8088">#8088</a>).</p></li>
<li><p>A superfluous error that was produced when setting the <code class="docutils literal notranslate"><span class="pre">PATH</span></code> or <code class="docutils literal notranslate"><span class="pre">CDPATH</span></code> environment variables to include colon-delimited components that do not exist was removed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8095">#8095</a>).</p></li>

<h3>Deprecations and removed features<a class="headerlink" href="#id56" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>The <code class="docutils literal notranslate"><span class="pre">$fish_history</span></code> value “default” is no longer special. It used to be treated the same as “fish” (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7650">#7650</a>).</p></li>
<li><p>Redirection to standard error with the <code class="docutils literal notranslate"><span class="pre">^</span></code> character has been disabled by default.

<h3>Scripting improvements<a class="headerlink" href="#id57" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">math</span></code> gained new functions <code class="docutils literal notranslate"><span class="pre">log2</span></code> (like the documentation claimed), <code class="docutils literal notranslate"><span class="pre">max</span></code> and <code class="docutils literal notranslate"><span class="pre">min</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7856">#7856</a>). <code class="docutils literal notranslate"><span class="pre">math</span></code> functions can be used without the parentheses (eg <code class="docutils literal notranslate"><span class="pre">math</span> <span class="pre">sin</span> <span class="pre">2</span> <span class="pre">+</span> <span class="pre">6</span></code>), and functions have the lowest precedence in the order of operations (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7877">#7877</a>).</p></li>
<li><p>Shebang (<code class="docutils literal notranslate"><span class="pre">#!</span></code>) lines are no longer required within shell scripts, improving support for scripts with concatenated binary contents. If a file fails to execute and passes a (rudimentary) binary safety check, fish will re-invoke it using <code class="docutils literal notranslate"><span class="pre">/bin/sh</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7802">#7802</a>).</p></li>
<li><p>Exit codes are better aligned with bash. A failed execution now reports <code class="docutils literal notranslate"><span class="pre">$status</span></code> of 127 if the file is not found, and 126 if it is not executable.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">echo</span></code> no longer writes its output one byte at a time, improving performance and allowing use with Linux’s special API files (<code class="docutils literal notranslate"><span class="pre">/proc</span></code>, <code class="docutils literal notranslate"><span class="pre">/sys</span></code> and such) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7836">#7836</a>).</p></li>
<li><p>fish should now better handle <code class="docutils literal notranslate"><span class="pre">cd</span></code> on filesystems with broken <code class="docutils literal notranslate"><span class="pre">stat(3)</span></code> responses (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7577">#7577</a>).</p></li>
<li><p>Builtins now properly report a <code class="docutils literal notranslate"><span class="pre">$status</span></code> of 1 upon unsuccessful writes (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7857">#7857</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">match</span></code> with unmatched capture groups and without the <code class="docutils literal notranslate"><span class="pre">--all</span></code> flag now sets an empty variable instead of a variable containing the empty string. It also correctly imports the first match if multiple arguments are provided, matching the documentation. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7938">#7938</a>).</p></li>
<li><p>fish produces more specific errors when a command in a command substitution wasn’t found or is not allowed. This now prints something like “Unknown command” instead of “Unknown error while evaluating command substitution”.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_indent</span></code> allows inline variable assignments (<code class="docutils literal notranslate"><span class="pre">FOO=BAR</span> <span class="pre">command</span></code>) to use line continuation, instead of joining them into one line (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7955">#7955</a>).</p></li>
<li><p>fish gained a <code class="docutils literal notranslate"><span class="pre">--no-config</span></code> option to disable configuration files. This applies to user-specific and the systemwide <code class="docutils literal notranslate"><span class="pre">config.fish</span></code> (typically in <code class="docutils literal notranslate"><span class="pre">/etc/fish/config.fish</span></code>), and configuration snippets (typically in <code class="docutils literal notranslate"><span class="pre">conf.d</span></code> directories). It also disables universal variables, history, and loading of functions from system or user configuration directories (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7921">#7921</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1256">#1256</a>).</p></li>
<li><p>When universal variables are unavailable for some reason, setting a universal variable now sets a global variable instead (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7921">#7921</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">$last_pid</span></code> now contains the process ID of the last process in the pipeline, allowing it to be used in scripts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5036">#5036</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5832">#5832</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7721">#7721</a>). Previously, this value contained the process group ID, but in scripts this was the same as the running fish’s process ID.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">process-exit</span></code> event handlers now receive the same value as <code class="docutils literal notranslate"><span class="pre">$status</span></code> in all cases, instead of receiving -1 when the exit was due to a signal.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">process-exit</span></code> event handlers for PID 0 also received <code class="docutils literal notranslate"><span class="pre">JOB_EXIT</span></code> events; this has been fixed.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">job-exit</span></code> event handlers may now be created with any of the PIDs from the job. The handler is passed the last PID in the job as its second argument, instead of the process group.</p></li>
<li><p>Trying to set an empty variable name with <code class="docutils literal notranslate"><span class="pre">set</span></code> no longer works (these variables could not be used in expansions anyway).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_add_path</span></code> handles an undefined <code class="docutils literal notranslate"><span class="pre">PATH</span></code> environment variable correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/8082">#8082</a>).</p></li>

<li><p>Performance of the “informative” git prompt is improved somewhat (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7871">#7871</a>). This is still slower than the non-informative version by its very nature. In particular it is IO-bound, so it will be very slow on slow disks or network mounts.</p></li>
<li><p>The sample prompts were updated. Some duplicated prompts, like the various classic variants, or less useful ones, like the “justadollar” prompt were removed, some prompts were cleaned up, and in some cases renamed. A new “simple” and “disco” prompt were added (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7884">#7884</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7897">#7897</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7930">#7930</a>).

<h2>fish 3.2.1 (released March 18, 2021)<a class="headerlink" href="#fish-3-2-1-released-march-18-2021" title="Link to this heading">¶</a></h2>
<p>This release of fish fixes the following problems identified in fish 3.2.0:</p>
<ul class="simple">
<li><p>Commands in key bindings are run with fish’s internal terminal modes, instead of the terminal modes typically used for commands. This fixes a bug introduced in 3.2.0, where text would unexpectedly appear on the terminal, especially when pasting (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7770">#7770</a>).</p></li>
<li><p>Prompts which use the internal <code class="docutils literal notranslate"><span class="pre">__fish_print_pipestatus</span></code> function will display correctly rather than carrying certain modifiers (such as bold) further than intended (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7771">#7771</a>).</p></li>
<li><p>Redirections to internal file descriptors is allowed again, reversing the changes in 3.2.0. This fixes a problem with Midnight Commander (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7769">#7769</a>).</p></li>
<li><p>Universal variables should be fully reliable regardless of operating system again (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7774">#7774</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_git_prompt</span></code> no longer causes screen flickering in certain terminals (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7775">#7775</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_add_path</span></code> manipulates the <code class="docutils literal notranslate"><span class="pre">fish_user_paths</span></code> variable correctly when moving multiple paths (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7776">#7776</a>).</p></li>

<li><p>Changing terminal modes inside <code class="docutils literal notranslate"><span class="pre">config.fish</span></code> works (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7783">#7783</a>).</p></li>

<li><p>Completing commands starting with a <code class="docutils literal notranslate"><span class="pre">-</span></code> no longer prints an error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7809">#7809</a>).</p></li>
<li><p>Running <code class="docutils literal notranslate"><span class="pre">fish_command_not_found</span></code> directly no longer produces an error on macOS or other OSes which do not have a handler available (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7777">#7777</a>).</p></li>
<li><p>The new <code class="docutils literal notranslate"><span class="pre">type</span></code> builtin now has the (deprecated) <code class="docutils literal notranslate"><span class="pre">--quiet</span></code> long form of <code class="docutils literal notranslate"><span class="pre">-q</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7766">#7766</a>).</p></li>

<li><p>The history file can be made a symbolic link without it being overwritten (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7754">#7754</a>), matching a similar improvement for the universal variable file in 3.2.0.</p></li>
<li><p>An unhelpful error (“access: No error”), seen on Cygwin, is no longer produced (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7785">#7785</a>).</p></li>

<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="c"># Show all dmesg lines related to "usb"</span>
<span class="nf">dmesg</span><span class="w"> </span><span class="no">-w</span><span class="w"> </span><span class="p">|</span><span class="w"> </span><span class="nf">string</span><span class="w"> </span><span class="no">match</span><span class="w"> </span><span class="s1">'*usb*'</span>
</pre></div>
</div>
</li>
<li><p><strong>Prompts will now be truncated</strong> instead of replaced with <code class="docutils literal notranslate"><span class="pre">"></span> <span class="pre">"</span></code> if they are wider than the terminal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/904">#904</a>).
For example:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="o">~</span><span class="nf">/dev/build/fish-shell-git/src/fish-shell/build</span><span class="w"> </span><span class="o">(</span><span class="nf">makepkg</span><span class="o">)</span><span class="p">></span>
</pre></div>
</div>
<p>will turn into:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">…h-shell/build</span><span class="w"> </span><span class="o">(</span><span class="nf">makepkg</span><span class="o">)</span><span class="p">></span>
</pre></div>
</div>
<p>It is still possible to react to the <code class="docutils literal notranslate"><span class="pre">COLUMNS</span></code> variable inside the prompt to implement smarter behavior.</p>
</li>
<li><p><strong>fish completes ambiguous completions</strong> after pressing <kbd class="kbd docutils literal notranslate">tab</kbd> even when they
have a common prefix, without the user having to press <kbd class="kbd docutils literal notranslate">tab</kbd> again
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6924">#6924</a>).</p></li>
<li><p>fish is less aggressive about resetting terminal modes, such as flow control, after every command.
Although flow control remains off by default, enterprising users can now enable it with
<code class="docutils literal notranslate"><span class="pre">stty</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2315">#2315</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7704">#7704</a>).</p></li>
<li><p>A new <strong>“fish_add_path” helper function to add paths to $PATH</strong> without producing duplicates,
to be used interactively or in <code class="docutils literal notranslate"><span class="pre">config.fish</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6960">#6960</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7028">#7028</a>).
For example:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">fish_add_path</span><span class="w"> </span><span class="no">/opt/mycoolthing/bin</span>
</pre></div>
</div>
<p>will add /opt/mycoolthing/bin to the beginning of $fish_user_path without creating duplicates,
so it can be called safely from config.fish or interactively, and the path will just be there, once.</p>
</li>
<li><p><strong>Better errors with “test”</strong> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6030">#6030</a>):</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="gp">> </span><span class="nf">test</span><span class="w"> </span><span class="no">1</span><span class="w"> </span><span class="no">=</span><span class="w"> </span><span class="no">2</span><span class="w"> </span><span class="no">and</span><span class="w"> </span><span class="no">echo</span><span class="w"> </span><span class="no">true</span><span class="w"> </span><span class="no">or</span><span class="w"> </span><span class="no">false</span>
<span class="go">test: Expected a combining operator like '-a' at index 4</span>
<span class="go">1 = 2 and echo true or echo false</span>
<span class="go"> ^</span>
</pre></div>
</div>
<p>This includes numbering the index from 1 instead of 0, like fish lists.</p>
</li>
<li><p><strong>A new theme for the documentation and Web-based configuration</strong> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6500">#6500</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7371">#7371</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7523">#7523</a>), matching the design on fishshell.com.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--no-execute</span></code> <strong>will no longer complain about unknown commands</strong>
or non-matching wildcards, as these could be defined differently at
runtime (especially for functions). This makes it usable as a static syntax checker (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/977">#977</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">match</span> <span class="pre">--regex</span></code> now integrates <strong>named PCRE2 capture groups as fish variables</strong>, allowing variables to be set directly from <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">match</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7459">#7459</a>). To support this functionality, <code class="docutils literal notranslate"><span class="pre">string</span></code> is now a reserved word and can no longer be wrapped in a function.</p></li>
<li><p>Globs and other <strong>expansions are limited to 512,288 results</strong> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7226">#7226</a>). Because operating systems limit the number of arguments to commands, larger values are unlikely to work anyway, and this helps to avoid hangs.</p></li>
<li><p>A new <strong>“fish for bash users” documentation page</strong> gives a quick overview of the scripting differences between bash and fish (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2382">#2382</a>), and the completion tutorial has also been moved out into its own document (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6709">#6709</a>).</p></li>

<li><p><code class="docutils literal notranslate"><span class="pre">set</span></code> and backgrounded jobs no longer overwrite <code class="docutils literal notranslate"><span class="pre">$pipestatus</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6820">#6820</a>), improving its use in command substitutions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6998">#6998</a>).</p></li>
<li><p>Computed (“electric”) variables such as <code class="docutils literal notranslate"><span class="pre">status</span></code> are now only global in scope, so <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-Uq</span> <span class="pre">status</span></code> returns false (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7032">#7032</a>).</p></li>
<li><p>The output for <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">--show</span></code> has been shortened, only mentioning the scopes in which a variable exists (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6944">#6944</a>).
In addition, it now shows if a variable is a path variable.</p></li>
<li><p>A new variable, <code class="docutils literal notranslate"><span class="pre">fish_kill_signal</span></code>, is set to the signal that terminated the last foreground job, or <code class="docutils literal notranslate"><span class="pre">0</span></code> if the job exited normally (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6824">#6824</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6822">#6822</a>).</p></li>

<li><p><code class="docutils literal notranslate"><span class="pre">string</span></code> subcommands now quit early when used with <code class="docutils literal notranslate"><span class="pre">--quiet</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7495">#7495</a>).</p></li>

<li><p><code class="docutils literal notranslate"><span class="pre">printf</span></code> no longer prints an error if not given an argument (not

<li><p>A new <code class="docutils literal notranslate"><span class="pre">fish_job_summary</span></code> function is called whenever a
background job stops or ends, or any job terminates from a signal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6959">#6959</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2727">#2727</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4319">#4319</a>).
The default behaviour can now be customized by redefining it.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">status</span></code> gained new <code class="docutils literal notranslate"><span class="pre">dirname</span></code> and <code class="docutils literal notranslate"><span class="pre">basename</span></code> convenience subcommands
to get just the directory to the running script or the name of it,
to simplify common tasks such as running <code class="docutils literal notranslate"><span class="pre">(dirname</span> <span class="pre">(status</span> <span class="pre">filename))</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7076">#7076</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1818">#1818</a>).</p></li>
<li><p>Broken pipelines are now handled more smoothly; in particular, bad redirection mid-pipeline
results in the job continuing to run but with the broken file descriptor replaced with a closed
file descriptor. This allows better error recovery and is more in line with other shells’
behaviour (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7038">#7038</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">jobs</span> <span class="pre">--quiet</span> <span class="pre">PID</span></code> no longer prints “no suitable job” if the job for PID does not exist (eg because it has finished) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6809">#6809</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6812">#6812</a>).</p></li>

<li><p><code class="docutils literal notranslate"><span class="pre">command</span></code>, <code class="docutils literal notranslate"><span class="pre">jobs</span></code> and <code class="docutils literal notranslate"><span class="pre">type</span></code> builtins support <code class="docutils literal notranslate"><span class="pre">--query</span></code> as the long form of <code class="docutils literal notranslate"><span class="pre">-q</span></code>, matching other builtins.
The long form <code class="docutils literal notranslate"><span class="pre">--quiet</span></code> is deprecated (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7276">#7276</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">argparse</span></code> no longer requires a short flag letter for long-only options (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7585">#7585</a>)
and only prints a backtrace with invalid options to argparse itself (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6703">#6703</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">argparse</span></code> now passes the validation variables (e.g. <code class="docutils literal notranslate"><span class="pre">$_flag_value</span></code>) as local-exported variables,
avoiding the need for <code class="docutils literal notranslate"><span class="pre">--no-scope-shadowing</span></code> in validation functions.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">complete</span></code> takes the first argument as the name of the command if the <code class="docutils literal notranslate"><span class="pre">--command</span></code>/<code class="docutils literal notranslate"><span class="pre">-c</span></code> option is not used,
so <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">git</span></code> is treated like <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">--command</span> <span class="pre">git</span></code>,
and it can show the loaded completions for specific commands with <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">COMMANDNAME</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7321">#7321</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set_color</span> <span class="pre">-b</span></code> (without an argument) no longer prints an error message, matching other invalid invocations of this command (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7154">#7154</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">exec</span></code> no longer produces a syntax error when the command cannot be found (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6098">#6098</a>).</p></li>

It can still return incorrect results in other cases (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1228">#1228</a>).</p></li>
<li><p>Trying to execute scripts with Windows line endings (CRLF) produces a sensible error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2783">#2783</a>).</p></li>
<li><p>Trying to execute commands with arguments that exceed the operating system limit now produces a specific error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6800">#6800</a>).</p></li>
<li><p>An <code class="docutils literal notranslate"><span class="pre">alias</span></code> that delegates to a command with the same name no longer triggers an error about recursive completion (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7389">#7389</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">math</span></code> now has a <code class="docutils literal notranslate"><span class="pre">--base</span></code> option to output the result in hexadecimal or octal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7496">#7496</a>) and produces more specific error messages (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7508">#7508</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">math</span></code> learned bitwise functions <code class="docutils literal notranslate"><span class="pre">bitand</span></code>, <code class="docutils literal notranslate"><span class="pre">bitor</span></code> and <code class="docutils literal notranslate"><span class="pre">bitxor</span></code>, used like <code class="docutils literal notranslate"><span class="pre">math</span> <span class="pre">"bitand(0xFE,</span> <span class="pre">5)"</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7281">#7281</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">math</span></code> learned tau for those who don’t like typing “2 * pi”.</p></li>

<li><p>fish sets exit status in a more consistent manner after errors, including invalid expansions like <code class="docutils literal notranslate"><span class="pre">$foo[</span></code>.</p></li>
<li><p>Using <code class="docutils literal notranslate"><span class="pre">read</span> <span class="pre">--silent</span></code> while fish is in private mode was adding these potentially-sensitive entries to the history; this has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7230">#7230</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">read</span></code> can now read interactively from other files, and can be used to read from the terminal via <code class="docutils literal notranslate"><span class="pre">read</span> <span class="pre"></dev/tty</span></code> (if the operating system provides <code class="docutils literal notranslate"><span class="pre">/dev/tty</span></code>) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7358">#7358</a>).</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">fish_status_to_signal</span></code> function for transforming exit statuses to signal names has been added (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7597">#7597</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7595">#7595</a>).</p></li>
<li><p>The fallback <code class="docutils literal notranslate"><span class="pre">realpath</span></code> builtin supports the <code class="docutils literal notranslate"><span class="pre">-s</span></code>/<code class="docutils literal notranslate"><span class="pre">--no-symlinks</span></code> option, like GNU realpath (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7574">#7574</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">functions</span></code> and <code class="docutils literal notranslate"><span class="pre">type</span></code> now explain when a function was defined via <code class="docutils literal notranslate"><span class="pre">source</span></code> instead of just saying <code class="docutils literal notranslate"><span class="pre">Defined</span> <span class="pre">in</span> <span class="pre">-</span></code>.</p></li>
<li><p>Significant performance improvements when globbing, appending to variables or in <code class="docutils literal notranslate"><span class="pre">math</span></code>.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">echo</span></code> no longer interprets options at the beginning of an argument (eg <code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">"-n</span> <span class="pre">foo"</span></code>) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7614">#7614</a>).</p></li>
<li><p>fish now finds user configuration even if the <code class="docutils literal notranslate"><span class="pre">HOME</span></code> environment variable is not set (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7620">#7620</a>).</p></li>
<li><p>fish no longer crashes when started from a Windows-style working directory (eg <code class="docutils literal notranslate"><span class="pre">F:\path</span></code>) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7636">#7636</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">-c</span></code> now reads the remaining arguments into <code class="docutils literal notranslate"><span class="pre">$argv</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2314">#2314</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">pwd</span></code> command supports the long options <code class="docutils literal notranslate"><span class="pre">--logical</span></code> and <code class="docutils literal notranslate"><span class="pre">--physical</span></code>, matching other implementations (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6787">#6787</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--profile</span></code> now only starts profiling after fish is ready to execute commands (all configuration is completed). There is a new <code class="docutils literal notranslate"><span class="pre">--profile-startup</span></code> option that only profiles the startup and configuration process (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7648">#7648</a>).</p></li>
<li><p>Builtins return a maximum exit status of 255, rather than potentially overflowing. In particular, this affects <code class="docutils literal notranslate"><span class="pre">exit</span></code>, <code class="docutils literal notranslate"><span class="pre">return</span></code>, <code class="docutils literal notranslate"><span class="pre">functions</span> <span class="pre">--query</span></code>, and <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">--query</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7698">#7698</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7702">#7702</a>).</p></li>
<li><p>It is no longer an error to run builtin with closed stdin. For example <code class="docutils literal notranslate"><span class="pre">count</span> <span class="pre"><&-</span></code> now prints 0, instead of failing.</p></li>
<li><p>Blocks, functions, and builtins no longer permit redirecting to file descriptors other than 0 (standard input), 1 (standard output) and 2 (standard error). For example, <code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">hello</span> <span class="pre">>&5</span></code> is now an error. This prevents corruption of internal state (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3303">#3303</a>).</p></li>

<h3>Interactive improvements<a class="headerlink" href="#id66" title="Link to this heading">¶</a></h3>
<ul>
<li><p>fish will now always attempt to become process group leader in interactive mode (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7060">#7060</a>). This helps avoid hangs in certain circumstances, and allows tmux’s current directory introspection to work (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5699">#5699</a>).</p></li>
<li><p>The interactive reader now allows ending a line in a logical operators (<code class="docutils literal notranslate"><span class="pre">&&</span></code> and <code class="docutils literal notranslate"><span class="pre">||</span></code>) instead of complaining about a missing command. (This was already syntactically valid, but interactive sessions didn’t know about it yet).</p></li>
<li><p>The prompt is reprinted after a background job exits (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1018">#1018</a>).</p></li>
<li><p>fish no longer inserts a space after a completion ending in <code class="docutils literal notranslate"><span class="pre">.</span></code>, <code class="docutils literal notranslate"><span class="pre">,</span></code> or <code class="docutils literal notranslate"><span class="pre">-</span></code> is accepted, improving completions for tools that provide dynamic completions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6928">#6928</a>).</p></li>
<li><p>If a filename is invalid when first pressing <kbd class="kbd docutils literal notranslate">tab</kbd>, but becomes valid, it will be completed properly on the next attempt (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6863">#6863</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">help</span> <span class="pre">string</span> <span class="pre">match/replace/<subcommand></span></code> will show the help for string subcommands (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6786">#6786</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_key_reader</span></code> sets the exit status to 0 when used with <code class="docutils literal notranslate"><span class="pre">--help</span></code> or <code class="docutils literal notranslate"><span class="pre">--version</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6964">#6964</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_key_reader</span></code> and <code class="docutils literal notranslate"><span class="pre">fish_indent</span></code> send output from <code class="docutils literal notranslate"><span class="pre">--version</span></code> to standard output, matching other fish binaries (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6964">#6964</a>).</p></li>
<li><p>A new variable <code class="docutils literal notranslate"><span class="pre">$status_generation</span></code> is incremented only when the previous command produces an exit status (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6815">#6815</a>). This can be used, for example, to check whether a failure status is a holdover due to a background job, or actually produced by the last run command.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_greeting</span></code> is now a function that reads a variable of the same name, and defaults to setting it globally.
This removes a universal variable by default and helps with updating the greeting.
However, to disable the greeting it is now necessary to explicitly specify universal scope (<code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-U</span> <span class="pre">fish_greeting</span></code>) or to disable it in config.fish (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7265">#7265</a>).</p></li>
<li><p>Events are properly emitted after a job is cancelled (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2356">#2356</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_preexec</span></code> and <code class="docutils literal notranslate"><span class="pre">fish_postexec</span></code> events are no longer triggered for empty commands (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4829">#4829</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7085">#7085</a>).</p></li>
<li><p>Functions triggered by the <code class="docutils literal notranslate"><span class="pre">fish_exit</span></code> event are correctly run when the terminal is closed or the shell receives SIGHUP (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7014">#7014</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_prompt</span></code> event no longer fires when <code class="docutils literal notranslate"><span class="pre">read</span></code> is used. If
you need a function to run any time <code class="docutils literal notranslate"><span class="pre">read</span></code> is invoked by a script,
use the new <code class="docutils literal notranslate"><span class="pre">fish_read</span></code> event instead (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7039">#7039</a>).</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">fish_posterror</span></code> event is emitted when attempting to execute a command with syntax errors (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6880">#6880</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6816">#6816</a>).</p></li>
<li><p>The debugging system has now fully switched from the old numbered level to the new named category system introduced in 3.1. A number of new debugging categories have been added, including <code class="docutils literal notranslate"><span class="pre">config</span></code>, <code class="docutils literal notranslate"><span class="pre">path</span></code>, <code class="docutils literal notranslate"><span class="pre">reader</span></code> and <code class="docutils literal notranslate"><span class="pre">screen</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6511">#6511</a>). See the output of <code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--print-debug-categories</span></code> for the full list.</p></li>
<li><p>The warning about read-only filesystems has been moved to a new “warning-path” debug category
and can be disabled by setting a debug category of <code class="docutils literal notranslate"><span class="pre">-warning-path</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6630">#6630</a>):</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">fish</span><span class="w"> </span><span class="no">--debug=-warning-path</span>
</pre></div>
</div>
</li>
<li><p>The enabled debug categories are now printed on shell startup (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7007">#7007</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">-o</span></code> short option to fish, for <code class="docutils literal notranslate"><span class="pre">--debug-output</span></code>, works correctly instead of producing an
invalid option error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7254">#7254</a>).</p></li>
<li><p>fish’s debugging can now also be enabled via <code class="docutils literal notranslate"><span class="pre">FISH_DEBUG</span></code> and <code class="docutils literal notranslate"><span class="pre">FISH_DEBUG_OUTPUT</span></code> environment variables.
This helps with debugging when no commandline options can be passed, like when fish is called in a shebang (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7359">#7359</a>).</p></li>
<li><p>Abbreviations are now expanded after all command terminators (eg <code class="docutils literal notranslate"><span class="pre">;</span></code> or <code class="docutils literal notranslate"><span class="pre">|</span></code>), not just space,
as in fish 2.7.1 and before (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6970">#6970</a>), and after closing a command substitution (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6658">#6658</a>).</p></li>
<li><p>The history file is now created with user-private permissions,
matching other shells (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6926">#6926</a>). The directory containing the history
file was already private, so there should not have been any private data
revealed.</p></li>
<li><p>The output of <code class="docutils literal notranslate"><span class="pre">time</span></code> is now properly aligned in all cases (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6726">#6726</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6714">#6714</a>) and no longer depends on locale (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6757">#6757</a>).</p></li>
<li><p>The command-not-found handling has been simplified.
When it can’t find a command, fish now just executes a function called <code class="docutils literal notranslate"><span class="pre">fish_command_not_found</span></code>
instead of firing an event, making it easier to replace and reason about.
Previously-defined <code class="docutils literal notranslate"><span class="pre">__fish_command_not_found_handler</span></code> functions with an appropriate event listener will still work (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7293">#7293</a>).</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">c</kbd> handling has been reimplemented in C++ and is therefore quicker (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5259">#5259</a>), no longer occasionally prints an “unknown command” error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7145">#7145</a>) or overwrites multiline prompts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3537">#3537</a>).</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">c</kbd> no longer kills background jobs for which job control is
disabled, matching POSIX semantics (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6828">#6828</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6861">#6861</a>).</p></li>
<li><p>Autosuggestions work properly after <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">c</kbd> cancels the current command line (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6937">#6937</a>).</p></li>
<li><p>History search is now case-insensitive unless the search string contains an uppercase character (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7273">#7273</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_update_completions</span></code> gained a new <code class="docutils literal notranslate"><span class="pre">--keep</span></code> option, which improves speed by skipping completions that already exist (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6775">#6775</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6796">#6796</a>).</p></li>
<li><p>Aliases containing an embedded backslash appear properly in the output of <code class="docutils literal notranslate"><span class="pre">alias</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6910">#6910</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">open</span></code> no longer hangs indefinitely on certain systems, as a bug in <code class="docutils literal notranslate"><span class="pre">xdg-open</span></code> has been worked around (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7215">#7215</a>).</p></li>
<li><p>Long command lines no longer add a blank line after execution (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6826">#6826</a>) and behave better with <kbd class="kbd docutils literal notranslate">backspace</kbd> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6951">#6951</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">functions</span> <span class="pre">-t</span></code> works like the long option <code class="docutils literal notranslate"><span class="pre">--handlers-type</span></code>, as documented, instead of producing an error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6985">#6985</a>).</p></li>
<li><p>History search now flashes when it found no more results (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7362">#7362</a>)</p></li>
<li><p>fish now creates the path in the environment variable <code class="docutils literal notranslate"><span class="pre">XDG_RUNTIME_DIR</span></code> if it does not exist, before using it for runtime data storage (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7335">#7335</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set_color</span> <span class="pre">--print-colors</span></code> now also respects the bold, dim, underline, reverse, italic and background modifiers, to better show their effect (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7314">#7314</a>).</p></li>
<li><p>The fish Web configuration tool (<code class="docutils literal notranslate"><span class="pre">fish_config</span></code>) shows prompts correctly on Termux for Android (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7298">#7298</a>) and detects Windows Services for Linux 2 properly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7027">#7027</a>). It no longer shows the <code class="docutils literal notranslate"><span class="pre">history</span></code> variable as it may be too large (one can use the History tab instead). It also starts the browser in another thread, avoiding hangs in some circumstances, especially with Firefox’s Developer Edition (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7158">#7158</a>). Finally, a bug in the Source Code Pro font may cause browsers to hang, so this font is no longer chosen by default (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7714">#7714</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">funcsave</span></code> gained a new <code class="docutils literal notranslate"><span class="pre">--directory</span></code> option to specify the location of the saved function (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7041">#7041</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">help</span></code> works properly on MSYS2 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7113">#7113</a>) and only uses <code class="docutils literal notranslate"><span class="pre">cmd.exe</span></code> if running on WSL (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6797">#6797</a>).</p></li>
<li><p>Resuming a piped job by its number, like <code class="docutils literal notranslate"><span class="pre">fg</span> <span class="pre">%1</span></code>, works correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7406">#7406</a>). Resumed jobs show the correct title in the terminal emulator (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7444">#7444</a>).</p></li>
<li><p>Commands run from key bindings now use the same TTY modes as normal commands (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7483">#7483</a>).</p></li>
<li><p>Autosuggestions from history are now case-sensitive (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3978">#3978</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">$status</span></code> from completion scripts is no longer passed outside the completion, which keeps the status display in the prompt as the last command’s status (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7555">#7555</a>).</p></li>
<li><p>Updated localisations for pt_BR (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7480">#7480</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_trace</span></code> output now starts with <code class="docutils literal notranslate"><span class="pre">-></span></code> (like <code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--profile</span></code>), making the depth more visible (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7538">#7538</a>).</p></li>
<li><p>Resizing the terminal window no longer produces a corrupted prompt (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6532">#6532</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7404">#7404</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">functions</span></code> produces an error rather than crashing on certain invalid arguments (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7515">#7515</a>).</p></li>
<li><p>A crash in completions with inline variable assignment (eg <code class="docutils literal notranslate"><span class="pre">A=</span> <span class="pre">b</span></code>) has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7344">#7344</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_private_mode</span></code> may now be changed dynamically using <code class="docutils literal notranslate"><span class="pre">set</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7589">#7589</a>), and history is kept in memory in private mode (but not stored permanently) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7590">#7590</a>).</p></li>
<li><p>Commands with leading spaces may be retrieved from history with up-arrow until a new command is run, matching zsh’s <code class="docutils literal notranslate"><span class="pre">HIST_IGNORE_SPACE</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1383">#1383</a>).</p></li>
<li><p>Importing bash history or reporting errors with recursive globs (<code class="docutils literal notranslate"><span class="pre">**</span></code>) no longer hangs (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7407">#7407</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7497">#7497</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">bind</span></code> now shows <code class="docutils literal notranslate"><span class="pre">\x7f</span></code> for the del key instead of a literal DEL character (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7631">#7631</a>)</p></li>
<li><p>Paths containing variables or tilde expansion are only suggested when they are still valid (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7582">#7582</a>).</p></li>
<li><p>Syntax highlighting can now color a command as invalid even if executed quickly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5912">#5912</a>).</p></li>
<li><p>Redirection targets are no longer highlighted as error if they contain variables which will likely be defined by the current commandline (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6654">#6654</a>).</p></li>
<li><p>fish is now more resilient against broken terminal modes (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7133">#7133</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4873">#4873</a>).</p></li>

<h4>New or improved bindings<a class="headerlink" href="#id67" title="Link to this heading">¶</a></h4>
<ul class="simple">
<li><p>As mentioned above, new special input functions <code class="docutils literal notranslate"><span class="pre">undo</span></code> (<kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">_</kbd> or <kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">z</kbd>) and <code class="docutils literal notranslate"><span class="pre">redo</span></code> (<kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">/</kbd>) can be used to revert changes to the command line or the pager search field (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6570">#6570</a>).</p></li>
<li><p><kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">z</kbd> is now available for binding (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7152">#7152</a>).</p></li>
<li><p>Additionally, using the <code class="docutils literal notranslate"><span class="pre">cancel</span></code> special input function (bound to <kbd class="kbd docutils literal notranslate">escape</kbd> by default) right after fish picked an unambiguous completion will undo that (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7433">#7433</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_clipboard_paste</span></code> (<kbd class="kbd docutils literal notranslate">ctrl</kbd>-<kbd class="kbd docutils literal notranslate">v</kbd>) trims indentation from multiline commands, because fish already indents (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7662">#7662</a>).</p></li>
<li><p>Vi mode bindings now support <code class="docutils literal notranslate"><span class="pre">dh</span></code>, <code class="docutils literal notranslate"><span class="pre">dl</span></code>, <code class="docutils literal notranslate"><span class="pre">c0</span></code>, <code class="docutils literal notranslate"><span class="pre">cf</span></code>, <code class="docutils literal notranslate"><span class="pre">ct</span></code>, <code class="docutils literal notranslate"><span class="pre">cF</span></code>, <code class="docutils literal notranslate"><span class="pre">cT</span></code>, <code class="docutils literal notranslate"><span class="pre">ch</span></code>, <code class="docutils literal notranslate"><span class="pre">cl</span></code>, <code class="docutils literal notranslate"><span class="pre">y0</span></code>, <code class="docutils literal notranslate"><span class="pre">ci</span></code>, <code class="docutils literal notranslate"><span class="pre">ca</span></code>, <code class="docutils literal notranslate"><span class="pre">yi</span></code>, <code class="docutils literal notranslate"><span class="pre">ya</span></code>, <code class="docutils literal notranslate"><span class="pre">di</span></code>, <code class="docutils literal notranslate"><span class="pre">da</span></code>, <code class="docutils literal notranslate"><span class="pre">d;</span></code>, <code class="docutils literal notranslate"><span class="pre">d,</span></code>, <code class="docutils literal notranslate"><span class="pre">o</span></code>, <code class="docutils literal notranslate"><span class="pre">O</span></code> and Control+left/right keys to navigate by word (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6648">#6648</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6755">#6755</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6769">#6769</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7442">#7442</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7516">#7516</a>).</p></li>
<li><p>Vi mode bindings support <kbd class="kbd docutils literal notranslate">~</kbd> (tilde) to toggle the case of the selected character (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6908">#6908</a>).</p></li>

<li><p>If history search fails to find a match, the cursor is no longer moved. This is useful when accidentally starting a history search on a multi-line commandline.</p></li>
<li><p>The special input function <code class="docutils literal notranslate"><span class="pre">beginning-of-history</span></code> (<kbd class="kbd docutils literal notranslate">pageup</kbd>) now moves to the oldest search instead of the youngest - that’s <code class="docutils literal notranslate"><span class="pre">end-of-history</span></code> (<kbd class="kbd docutils literal notranslate">pagedown</kbd>).</p></li>
<li><p>A new special input function <code class="docutils literal notranslate"><span class="pre">forward-single-char</span></code> moves one character to the right, and if an autosuggestion is available, only take a single character from it (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7217">#7217</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4984">#4984</a>).</p></li>
<li><p>Special input functions can now be joined with <code class="docutils literal notranslate"><span class="pre">or</span></code> as a modifier (adding to <code class="docutils literal notranslate"><span class="pre">and</span></code>), though only some commands set an exit status (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7217">#7217</a>). This includes <code class="docutils literal notranslate"><span class="pre">suppress-autosuggestion</span></code> to reflect whether an autosuggestion was suppressed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1419">#1419</a>)</p></li>
<li><p>A new function <code class="docutils literal notranslate"><span class="pre">__fish_preview_current_file</span></code>, bound to <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">o</kbd>, opens the

<li><p><code class="docutils literal notranslate"><span class="pre">__fish_prepend_sudo</span></code> (<kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">s</kbd>) now toggles a <code class="docutils literal notranslate"><span class="pre">sudo</span></code> prefix (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7012">#7012</a>) and avoids shifting the cursor (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6542">#6542</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">__fish_prepend_sudo</span></code> (<kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">s</kbd>) now uses the previous commandline if the current one is empty,

<li><p><code class="docutils literal notranslate"><span class="pre">__fish_toggle_comment_commandline</span></code> (<kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">#</kbd>) now uncomments and presents the last comment
from history if the commandline is empty (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7137">#7137</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">__fish_whatis_current_token</span></code> (<kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">w</kbd>) prints descriptions for functions and builtins (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7191">#7191</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2083">#2083</a>).</p></li>
<li><p>The definition of “word” and “bigword” for movements was refined, fixing (eg) vi mode’s behavior with <kbd class="kbd docutils literal notranslate">e</kbd> on the second-to-last char, and bigword’s behavior with single-character words and non-blank non-graphical characters (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7353">#7353</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7354">#7354</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4025">#4025</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7328">#7328</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7325">#7325</a>)</p></li>
<li><p>fish’s clipboard bindings now also support Windows Subsystem for Linux via PowerShell and clip.exe (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7455">#7455</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7458">#7458</a>) and will properly copy newlines in multi-line commands.</p></li>
<li><p>Using the <code class="docutils literal notranslate"><span class="pre">*-jump</span></code> special input functions before typing anything else no longer crashes fish.</p></li>
<li><p>Completing variable overrides (<code class="docutils literal notranslate"><span class="pre">foo=bar</span></code>) could replace the entire thing with just the completion in some circumstances. This has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7398">#7398</a>).</p></li>

shape in vi mode, regardless of terminal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6968">#6968</a>).

<li><p>Completion scripts for custom Git subcommands like <code class="docutils literal notranslate"><span class="pre">git-xyz</span></code> are now loaded with Git completions. The completions can now be defined directly on the subcommand (using <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">git-xyz</span></code>), and completion for <code class="docutils literal notranslate"><span class="pre">git</span> <span class="pre">xyz</span></code> will work. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7075">#7075</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7652">#7652</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4358">#4358</a>)</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">make</span></code> completions no longer second-guess make’s file detection, fixing target completion in some cases (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7535">#7535</a>).</p></li>
<li><p>Command completions now correctly print the description even if the command was fully matched (like in <code class="docutils literal notranslate"><span class="pre">ls<TAB></span></code>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set</span></code> completions no longer hide variables starting with <code class="docutils literal notranslate"><span class="pre">__</span></code>, they are sorted last instead.</p></li>

<li><p>Significant performance improvements to completion of the available commands (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7153">#7153</a>), especially on macOS Big Sur where there was a significant regression (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7365">#7365</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7511">#7511</a>).</p></li>
<li><p>Suffix completion using <code class="docutils literal notranslate"><span class="pre">__fish_complete_suffix</span></code> uses the same fuzzy matching logic as normal file completion, and completes any file but sorts files with matching suffix first (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7040">#7040</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7547">#7547</a>).

<h3>Deprecations and removed features<a class="headerlink" href="#id72" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_color_match</span></code> variable is no longer used. (Previously this controlled the color of matching quotes and parens when using <code class="docutils literal notranslate"><span class="pre">read</span></code>).</p></li>
<li><p>fish 3.2.0 will be the last release in which the redirection to standard error with the <code class="docutils literal notranslate"><span class="pre">^</span></code> character is enabled.
The <code class="docutils literal notranslate"><span class="pre">stderr-nocaret</span></code> feature flag will be changed to “on” in future releases.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span></code> is now a reserved word and cannot be used for function names (see above).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_vi_cursor</span></code>’s option <code class="docutils literal notranslate"><span class="pre">--force-iterm</span></code> has been deprecated (see above).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">command</span></code>, <code class="docutils literal notranslate"><span class="pre">jobs</span></code> and <code class="docutils literal notranslate"><span class="pre">type</span></code> long-form option <code class="docutils literal notranslate"><span class="pre">--quiet</span></code> is deprecated in favor of <code class="docutils literal notranslate"><span class="pre">--query</span></code> (see above).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_command_not_found</span></code> event is no longer emitted, instead there is a function of that name.
By default it will call a previously-defined <code class="docutils literal notranslate"><span class="pre">__fish_command_not_found_handler</span></code>. To emit the event manually use <code class="docutils literal notranslate"><span class="pre">emit</span> <span class="pre">fish_command_not_found</span></code>.</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_prompt</span></code> event no longer fires when <code class="docutils literal notranslate"><span class="pre">read</span></code> is used. If
you need a function to run any time <code class="docutils literal notranslate"><span class="pre">read</span></code> is invoked by a script,
use the new <code class="docutils literal notranslate"><span class="pre">fish_read</span></code> event instead (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7039">#7039</a>).</p></li>
<li><p>To disable the greeting message permanently it is no longer enough to just run <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">fish_greeting</span></code> interactively as it is
no longer implicitly a universal variable. Use <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-U</span> <span class="pre">fish_greeting</span></code> or disable it in config.fish with <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-g</span> <span class="pre">fish_greeting</span></code>.</p></li>
<li><p>The long-deprecated and non-functional <code class="docutils literal notranslate"><span class="pre">-m</span></code>/<code class="docutils literal notranslate"><span class="pre">--read-mode</span></code> options to <code class="docutils literal notranslate"><span class="pre">read</span></code> were removed in 3.1b1. Using the short form, or a never-implemented <code class="docutils literal notranslate"><span class="pre">-B</span></code> option, no longer crashes fish (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7659">#7659</a>).</p></li>
<li><p>With the addition of new categories for debug options, the old numbered debugging levels have been removed.</p></li>

<li><p>Support for Python 2 in fish’s tools (<code class="docutils literal notranslate"><span class="pre">fish_config</span></code> and the manual page completion generator) is no longer guaranteed. Please use Python 3.5 or later (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6537">#6537</a>).</p></li>
<li><p>The Web-based configuration tool is compatible with Python 3.10 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7600">#7600</a>) and no longer requires Python’s distutils package (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/7514">#7514</a>).</p></li>

have never worked in non-interactive sessions, and making them work
is an ongoing process.</p></li>
<li><p>Functions using <code class="docutils literal notranslate"><span class="pre">--on-variable</span></code> work reliably with variables which
are set implicitly (rather than with <code class="docutils literal notranslate"><span class="pre">set</span></code>), such as

<h3>Errata for fish 3.1<a class="headerlink" href="#errata-for-fish-3-1" title="Link to this heading">¶</a></h3>
<p>A new builtin, <code class="docutils literal notranslate"><span class="pre">time</span></code>, was introduced in the fish 3.1 releases. This
builtin is a reserved word (like <code class="docutils literal notranslate"><span class="pre">test</span></code>, <code class="docutils literal notranslate"><span class="pre">function</span></code>, and others)
because of the way it is implemented, and functions can no longer be
named <code class="docutils literal notranslate"><span class="pre">time</span></code>. This was not clear in the fish 3.1b1 changelog.</p>

<span id="id74"></span><h3>Notable improvements and fixes<a class="headerlink" href="#notable-improvements-and-fixes-1" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>A new <code class="docutils literal notranslate"><span class="pre">$pipestatus</span></code> variable contains a list of exit statuses of
the previous job, for each of the separate commands in a pipeline
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5632">#5632</a>).</p></li>
<li><p>fish no longer buffers pipes to the last function in a pipeline,
improving many cases where pipes appeared to block or hang (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1396">#1396</a>).</p></li>
<li><p>An overhaul of error messages for builtin commands, including a
removal of the overwhelming usage summary, more readable stack traces
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3404">#3404</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5434">#5434</a>), and stack traces for <code class="docutils literal notranslate"><span class="pre">test</span></code> (aka <code class="docutils literal notranslate"><span class="pre">[</span></code>) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5771">#5771</a>).</p></li>
<li><p>fish’s debugging arguments have been significantly improved. The
<code class="docutils literal notranslate"><span class="pre">--debug-level</span></code> option has been removed, and a new <code class="docutils literal notranslate"><span class="pre">--debug</span></code>
option replaces it. This option accepts various categories, which may
be listed via <code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--print-debug-categories</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5879">#5879</a>). A new
<code class="docutils literal notranslate"><span class="pre">--debug-output</span></code> option allows for redirection of debug output.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span></code> has a new <code class="docutils literal notranslate"><span class="pre">collect</span></code> subcommand for use in command
substitutions, producing a single output instead of splitting on new
lines (similar to <code class="docutils literal notranslate"><span class="pre">"$(cmd)"</span></code> in other shells) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/159">#159</a>).</p></li>
<li><p>The fish manual, tutorial and FAQ are now available in <code class="docutils literal notranslate"><span class="pre">man</span></code> format
as <code class="docutils literal notranslate"><span class="pre">fish-doc</span></code>, <code class="docutils literal notranslate"><span class="pre">fish-tutorial</span></code> and <code class="docutils literal notranslate"><span class="pre">fish-faq</span></code> respectively
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5521">#5521</a>).</p></li>
<li><p>Like other shells, <code class="docutils literal notranslate"><span class="pre">cd</span></code> now always looks for its argument in the
current directory as a last resort, even if the <code class="docutils literal notranslate"><span class="pre">CDPATH</span></code> variable
does not include it or “.” (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4484">#4484</a>).</p></li>
<li><p>fish now correctly handles <code class="docutils literal notranslate"><span class="pre">CDPATH</span></code> entries that start with <code class="docutils literal notranslate"><span class="pre">..</span></code>
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6220">#6220</a>) or contain <code class="docutils literal notranslate"><span class="pre">./</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5887">#5887</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_trace</span></code> variable may be set to trace execution (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3427">#3427</a>).
This performs a similar role as <code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-x</span></code> in other shells.</p></li>
<li><p>fish uses the temporary directory determined by the system, rather
than relying on <code class="docutils literal notranslate"><span class="pre">/tmp</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3845">#3845</a>).</p></li>
<li><p>The fish Web configuration tool (<code class="docutils literal notranslate"><span class="pre">fish_config</span></code>) prints a list of
commands it is executing, to help understanding and debugging
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5584">#5584</a>).</p></li>
<li><p>Major performance improvements when pasting (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5866">#5866</a>), executing lots
of commands (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5905">#5905</a>), importing history from bash (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6295">#6295</a>), and when
completing variables that might match <code class="docutils literal notranslate"><span class="pre">$history</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6288">#6288</a>).</p></li>

<span id="id75"></span><h3>Syntax changes and new commands<a class="headerlink" href="#syntax-changes-and-new-commands-1" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>A new builtin command, <code class="docutils literal notranslate"><span class="pre">time</span></code>, which allows timing of fish
functions and builtins as well as external commands (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/117">#117</a>).</p></li>
<li><p>Brace expansion now only takes place if the braces include a “,” or a
variable expansion, meaning common commands such as
<code class="docutils literal notranslate"><span class="pre">git</span> <span class="pre">reset</span> <span class="pre">HEAD@{0}</span></code> do not require escaping (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5869">#5869</a>).</p></li>
<li><p>New redirections <code class="docutils literal notranslate"><span class="pre">&></span></code> and <code class="docutils literal notranslate"><span class="pre">&|</span></code> may be used to redirect or pipe
stdout, and also redirect stderr to stdout (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6192">#6192</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">switch</span></code> now allows arguments that expand to nothing, like empty
variables (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5677">#5677</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">VAR=val</span> <span class="pre">cmd</span></code> syntax can now be used to run a command in a
modified environment (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6287">#6287</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">and</span></code> is no longer recognised as a command, so that nonsensical
constructs like <code class="docutils literal notranslate"><span class="pre">and</span> <span class="pre">and</span> <span class="pre">and</span></code> produce a syntax error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6089">#6089</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">math</span></code>‘s exponent operator,’<code class="docutils literal notranslate"><span class="pre">^</span></code>‘, was previously
left-associative, but now uses the more commonly-used
right-associative behaviour (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6280">#6280</a>). This means that
<code class="docutils literal notranslate"><span class="pre">math</span> <span class="pre">'3^0.5^2'</span></code> was previously calculated as’(3<sup>0.5)</sup>2’,
but is now calculated as ‘3<sup>(0.5</sup>2)’.</p></li>
<li><p>In fish 3.0, the variable used with <code class="docutils literal notranslate"><span class="pre">for</span></code> loops inside command
substitutions could leak into enclosing scopes; this was an
inadvertent behaviour change and has been reverted (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6480">#6480</a>).</p></li>

<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">split0</span></code> now returns 0 if it split something (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5701">#5701</a>).</p></li>
<li><p>In the interest of consistency, <code class="docutils literal notranslate"><span class="pre">builtin</span> <span class="pre">-q</span></code> and <code class="docutils literal notranslate"><span class="pre">command</span> <span class="pre">-q</span></code> can

<li><p><code class="docutils literal notranslate"><span class="pre">math</span></code> now accepts <code class="docutils literal notranslate"><span class="pre">--scale=max</span></code> for the maximum scale (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5579">#5579</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">builtin</span> <span class="pre">$var</span></code> now works correctly, allowing a variable as the
builtin name (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5639">#5639</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">cd</span></code> understands the <code class="docutils literal notranslate"><span class="pre">--</span></code> argument to make it possible to change
to directories starting with a hyphen (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6071">#6071</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">--do-complete</span></code> now also does fuzzy matches (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5467">#5467</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">--do-complete</span></code> can be used inside completions, allowing
limited recursion (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3474">#3474</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">count</span></code> now also counts lines fed on standard input (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5744">#5744</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">eval</span></code> produces an exit status of 0 when given no arguments, like
other shells (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5692">#5692</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">printf</span></code> prints what it can when input hasn’t been fully converted
to a number, but still prints an error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5532">#5532</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">-C</span> <span class="pre">foo</span></code> now works as expected, rather than requiring
<code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">-Cfoo</span></code>.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">complete</span></code> has a new <code class="docutils literal notranslate"><span class="pre">--force-files</span></code> option, to re-enable file
completions. This allows <code class="docutils literal notranslate"><span class="pre">sudo</span> <span class="pre">-E</span></code> and <code class="docutils literal notranslate"><span class="pre">pacman</span> <span class="pre">-Qo</span></code> to complete
correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5646">#5646</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">argparse</span></code> now defaults to showing the current function name
(instead of <code class="docutils literal notranslate"><span class="pre">argparse</span></code>) in its errors, making <code class="docutils literal notranslate"><span class="pre">--name</span></code> often
superfluous (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5835">#5835</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">argparse</span></code> has a new <code class="docutils literal notranslate"><span class="pre">--ignore-unknown</span></code> option to keep
unrecognized options, allowing multiple argparse passes to parse
options (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5367">#5367</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">argparse</span></code> correctly handles flag value validation of options that

<li><p><code class="docutils literal notranslate"><span class="pre">read</span> <span class="pre">-S</span></code> (short option of <code class="docutils literal notranslate"><span class="pre">--shell</span></code>) is recognised correctly
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5660">#5660</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">read</span></code> understands <code class="docutils literal notranslate"><span class="pre">--list</span></code>, which acts like <code class="docutils literal notranslate"><span class="pre">--array</span></code> in
reading all arguments into a list inside a single variable, but is
better named (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5846">#5846</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">read</span></code> has a new option, <code class="docutils literal notranslate"><span class="pre">--tokenize</span></code>, which splits a string into
variables according to the shell’s tokenization rules, considering
quoting, escaping, and so on (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3823">#3823</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">read</span></code> interacts more correctly with the deprecated <code class="docutils literal notranslate"><span class="pre">$IFS</span></code>
variable, in particular removing multiple separators when splitting a
variable into a list (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6406">#6406</a>), matching other shells.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_indent</span></code> now handles semicolons better, including leaving them
in place for <code class="docutils literal notranslate"><span class="pre">;</span> <span class="pre">and</span></code> and <code class="docutils literal notranslate"><span class="pre">;</span> <span class="pre">or</span></code> instead of breaking the line

<li><p>fish only parses <code class="docutils literal notranslate"><span class="pre">/etc/paths</span></code> on macOS in login shells, matching
the bash implementation (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5637">#5637</a>) and avoiding changes to path ordering
in child shells (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5456">#5456</a>). It now ignores blank lines like the bash
implementation (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5809">#5809</a>).</p></li>
<li><p>The locale is now reloaded when the <code class="docutils literal notranslate"><span class="pre">LOCPATH</span></code> variable is changed
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5815">#5815</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">read</span></code> no longer keeps a history, making it suitable for operations
that shouldn’t end up there, like password entry (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5904">#5904</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">dirh</span></code> outputs its stack in the correct order (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5477">#5477</a>), and behaves
as documented when universal variables are used for its stack
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5797">#5797</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">funced</span></code> and the edit-commandline-in-buffer bindings did not work
in fish 3.0 when the <code class="docutils literal notranslate"><span class="pre">$EDITOR</span></code> variable contained spaces; this has
been corrected (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5625">#5625</a>).</p></li>
<li><p>Builtins now pipe their help output to a pager automatically (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6227">#6227</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set_color</span></code> now colors the <code class="docutils literal notranslate"><span class="pre">--print-colors</span></code> output in the

<li><p>fish now underlines every valid entered path instead of just the last
one (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5872">#5872</a>).</p></li>
<li><p>When syntax highlighting a string with an unclosed quote, only the
quote itself will be shown as an error, instead of the whole
argument.</p></li>
<li><p>Syntax highlighting works correctly with variables as commands
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5658">#5658</a>) and redirections to close file descriptors (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6092">#6092</a>).</p></li>

<li><p>A bug where <code class="docutils literal notranslate"><span class="pre">disown</span></code> could crash the shell has been fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5720">#5720</a>).</p></li>
<li><p>fish will not autosuggest files ending with <code class="docutils literal notranslate"><span class="pre">~</span></code> unless there are no
other candidates, as these are generally backup files (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/985">#985</a>).</p></li>
<li><p>Escape in the pager works correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5818">#5818</a>).</p></li>
<li><p>Key bindings that call <code class="docutils literal notranslate"><span class="pre">fg</span></code> no longer leave the terminal in a
broken state (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2114">#2114</a>).</p></li>
<li><p>Brackets (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5831">#5831</a>) and filenames containing <code class="docutils literal notranslate"><span class="pre">$</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6060">#6060</a>) are completed
with appropriate escaping.</p></li>
<li><p>The output of <code class="docutils literal notranslate"><span class="pre">complete</span></code> and <code class="docutils literal notranslate"><span class="pre">functions</span></code> is now colorized in

<li><p>The Web-based configuration handles aliases that include single
quotes correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6120">#6120</a>), and launches correctly under Termux (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6248">#6248</a>)

<li><p><code class="docutils literal notranslate"><span class="pre">function</span></code> now correctly validates parameters for

parses options following <code class="docutils literal notranslate"><span class="pre">--argument-names</span></code>, as in
“<code class="docutils literal notranslate"><span class="pre">--argument-names</span> <span class="pre">foo</span> <span class="pre">--description</span> <span class="pre">bar</span></code>” (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6186">#6186</a>).</p></li>
<li><p>History newly imported from bash includes command lines using <code class="docutils literal notranslate"><span class="pre">&&</span></code>
or <code class="docutils literal notranslate"><span class="pre">||</span></code>.</p></li>
<li><p>The automatic generation of completions from manual pages is better
described in job and process listings, and no longer produces a
warning when exiting fish (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6269">#6269</a>).</p></li>
<li><p>In private mode, setting <code class="docutils literal notranslate"><span class="pre">$fish_greeting</span></code> to an empty string before
starting the private session will prevent the warning about history
not being saved from being printed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6299">#6299</a>).</p></li>
<li><p>In the interactive editor, a line break (Enter) inside unclosed
brackets will insert a new line, rather than executing the command
and producing an error (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6316">#6316</a>).</p></li>
<li><p>Ctrl-C always repaints the prompt (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6394">#6394</a>).</p></li>
<li><p>When run interactively from another program (such as Python), fish
will correctly start a new process group, like other shells (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5909">#5909</a>).</p></li>
<li><p>Job identifiers (for example, for background jobs) are assigned more
logically (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6053">#6053</a>).</p></li>
<li><p>A bug where history would appear truncated if an empty command was
executed was fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6032">#6032</a>).</p></li>

from the history (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4327">#4327</a>).</p></li>
<li><p>Shift-Left and Shift-Right now default to moving backwards and
forwards by one bigword (words separated by whitespace) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1505">#1505</a>).</p></li>
<li><p>The default escape delay (to differentiate between the escape key and
an alt-combination) has been reduced to 30ms, down from 300ms for the
default mode and 100ms for Vi mode (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3904">#3904</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">forward-bigword</span></code> binding now interacts correctly with
autosuggestions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5336">#5336</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_clipboard_*</span></code> functions support Wayland by using

(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5450">#5450</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">nextd</span></code> and <code class="docutils literal notranslate"><span class="pre">prevd</span></code> functions no longer print “Hit end of
history”, instead using a bell. They correctly store working
directories containing symbolic links (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6395">#6395</a>).</p></li>
<li><p>If a <code class="docutils literal notranslate"><span class="pre">fish_mode_prompt</span></code> function exists, Vi mode will only execute
it on mode-switch instead of the entire prompt. This should make it
much more responsive with slow prompts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5783">#5783</a>).</p></li>
<li><p>The path-component bindings (like Ctrl-w) now also stop at “:” and
“@”, because those are used to denote user and host in commands such
as <code class="docutils literal notranslate"><span class="pre">ssh</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5841">#5841</a>).</p></li>
<li><p>The NULL character can now be bound via <code class="docutils literal notranslate"><span class="pre">bind</span> <span class="pre">-k</span> <span class="pre">nul</span></code>. Terminals
often generate this character via control-space. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3189">#3189</a>).</p></li>
<li><p>A new readline command <code class="docutils literal notranslate"><span class="pre">expand-abbr</span></code> can be used to trigger
abbreviation expansion (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5762">#5762</a>).</p></li>
<li><p>A new readline command, <code class="docutils literal notranslate"><span class="pre">delete-or-exit</span></code>, removes a character to
the right of the cursor or exits the shell if the command line is
empty (moving this functionality out of the <code class="docutils literal notranslate"><span class="pre">delete-or-exit</span></code>
function).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">self-insert</span></code> readline command will now insert the binding
sequence, if not empty.</p></li>
<li><p>A new binding to prepend <code class="docutils literal notranslate"><span class="pre">sudo</span></code>, bound to Alt-S by default (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6140">#6140</a>).</p></li>
<li><p>The Alt-W binding to describe a command should now work better with
multiline prompts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6110">#6110</a>)</p></li>
<li><p>The Alt-H binding to open a command’s man page now tries to ignore
<code class="docutils literal notranslate"><span class="pre">sudo</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6122">#6122</a>).</p></li>

<code class="docutils literal notranslate"><span class="pre">forward</span></code>), was introduced (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6143">#6143</a>).</p></li>
<li><p>Vi mode now supports R to enter replace mode (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6342">#6342</a>), and <code class="docutils literal notranslate"><span class="pre">d0</span></code> to
delete the current line (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6292">#6292</a>).</p></li>
<li><p>In Vi mode, hitting Enter in replace-one mode no longer erases the
prompt (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6298">#6298</a>).</p></li>
<li><p>Selections in Vi mode are inclusive, matching the actual behaviour of

<ul class="simple">
<li><p>The vcs-prompt functions have been promoted to names without
double-underscore, so __fish_git_prompt is now fish_git_prompt,
__fish_vcs_prompt is now fish_vcs_prompt, __fish_hg_prompt is now
fish_hg_prompt and __fish_svn_prompt is now fish_svn_prompt. Shims
at the old names have been added, and the variables have kept their
old names (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5586">#5586</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">replace</span></code> has an additional round of escaping in the

(eg <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">replace</span> <span class="pre">-ra</span> <span class="pre">'([ab])'</span> <span class="pre">'\\\\\\\$1'</span> <span class="pre">a</span></code>). The new feature
flag <code class="docutils literal notranslate"><span class="pre">regex-easyesc</span></code> can be used to disable this, so that the same
effect can be achieved with

As a reminder,
the intention behind feature flags is that this will eventually
become the default and then only option, so scripts should be
updated.</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_vi_mode</span></code> function, deprecated in fish 2.3, has been
removed. Use <code class="docutils literal notranslate"><span class="pre">fish_vi_key_bindings</span></code> instead (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/6372">#6372</a>).</p></li>

<span id="id82"></span><h3>For distributors and developers<a class="headerlink" href="#for-distributors-and-developers-1" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>fish 3.0 introduced a CMake-based build system. In fish 3.1, both the
Autotools-based build and legacy Xcode build system have been
removed, leaving only the CMake build system. All distributors and
developers must install CMake.</p></li>
<li><p>fish now depends on the common <code class="docutils literal notranslate"><span class="pre">tee</span></code> external command, for the
<code class="docutils literal notranslate"><span class="pre">psub</span></code> process substitution function.</p></li>
<li><p>The documentation is now built with Sphinx. The old Doxygen-based
documentation system has been removed. Developers, and distributors
who wish to rebuild the documentation, must install Sphinx.</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">INTERNAL_WCWIDTH</span></code> build option has been removed, as fish now
always uses an internal <code class="docutils literal notranslate"><span class="pre">wcwidth</span></code> function. It has a number of
configuration options that make it more suitable for general use
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5777">#5777</a>).</p></li>
<li><p>mandoc can now be used to format the output from <code class="docutils literal notranslate"><span class="pre">--help</span></code> if
<code class="docutils literal notranslate"><span class="pre">nroff</span></code> is not installed, reducing the number of external
dependencies on systems with <code class="docutils literal notranslate"><span class="pre">mandoc</span></code> installed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5489">#5489</a>).</p></li>
<li><p>Some bugs preventing building on Solaris-derived systems such as
Illumos were fixed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5458">#5458</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5461">#5461</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5611">#5611</a>).</p></li>
<li><p>Completions for <code class="docutils literal notranslate"><span class="pre">npm</span></code>, <code class="docutils literal notranslate"><span class="pre">bower</span></code> and <code class="docutils literal notranslate"><span class="pre">yarn</span></code> no longer require the
<code class="docutils literal notranslate"><span class="pre">jq</span></code> utility for full functionality, but will use Python instead if
it is available.</p></li>
<li><p>The paths for completions, functions and configuration snippets have
been extended. On systems that define <code class="docutils literal notranslate"><span class="pre">XDG_DATA_DIRS</span></code>, each of the
directories in this variable are searched in the subdirectories
<code class="docutils literal notranslate"><span class="pre">fish/vendor_completions.d</span></code>, <code class="docutils literal notranslate"><span class="pre">fish/vendor_functions.d</span></code>, and
<code class="docutils literal notranslate"><span class="pre">fish/vendor_conf.d</span></code> respectively. On systems that do not define
this variable in the environment, the vendor directories are searched
for in both the installation prefix and the default “extra”
directory, which now defaults to <code class="docutils literal notranslate"><span class="pre">/usr/local</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5029">#5029</a>).</p></li>

<p>fish 3 is a major release, which introduces some breaking changes
alongside improved functionality. Although most existing scripts will
continue to work, they should be reviewed against the list contained in
the 3.0b1 release notes below.</p>
<p>Compared to the beta release of fish 3.0b1, fish version 3.0.0:</p>
<ul class="simple">
<li><p>builds correctly against musl libc (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5407">#5407</a>)</p></li>

<li><p>removes the history colouring introduced in 3.0b1, which did not
always work correctly</p></li>
</ul>
<p>There is one significant known issue which was not able to be corrected
before the release:</p>
<ul class="simple">
<li><p>fish 3.0.0 builds on Cygwin (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5423">#5423</a>), but does not run correctly
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5426">#5426</a>) and will result in a hanging terminal when started. Cygwin
users are encouraged to continue using 2.7.1 until a release which

<h3>Notable non-backward compatible changes<a class="headerlink" href="#notable-non-backward-compatible-changes" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>Process and job expansion has largely been removed. <code class="docutils literal notranslate"><span class="pre">%</span></code> will no
longer perform these expansions, except for <code class="docutils literal notranslate"><span class="pre">%self</span></code> for the PID of
the current shell. Additionally, job management commands (<code class="docutils literal notranslate"><span class="pre">disown</span></code>,
<code class="docutils literal notranslate"><span class="pre">wait</span></code>, <code class="docutils literal notranslate"><span class="pre">bg</span></code>, <code class="docutils literal notranslate"><span class="pre">fg</span></code> and <code class="docutils literal notranslate"><span class="pre">kill</span></code>) will expand job specifiers
starting with <code class="docutils literal notranslate"><span class="pre">%</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4230">#4230</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1202">#1202</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">x[1]</span> <span class="pre">x[2]</span> <span class="pre">a</span> <span class="pre">b</span></code>, to set multiple elements of an array at once,
is no longer valid syntax (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4236">#4236</a>).</p></li>
<li><p>A literal <code class="docutils literal notranslate"><span class="pre">{}</span></code> now expands to itself, rather than nothing. This
makes working with <code class="docutils literal notranslate"><span class="pre">find</span> <span class="pre">-exec</span></code> easier (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1109">#1109</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4632">#4632</a>).</p></li>
<li><p>Literally accessing a zero-index is now illegal syntax and is caught
by the parser (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4862">#4862</a>). (fish indices start at 1)</p></li>
<li><p>Successive commas in brace expansions are handled in less surprising
manner. For example, <code class="docutils literal notranslate"><span class="pre">{,,,}</span></code> expands to four empty strings rather
than an empty string, a comma and an empty string again (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3002">#3002</a>,
<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4632">#4632</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">for</span></code> loop control variables are no longer local to the <code class="docutils literal notranslate"><span class="pre">for</span></code>
block (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1935">#1935</a>).</p></li>
<li><p>Variables set in <code class="docutils literal notranslate"><span class="pre">if</span></code> and <code class="docutils literal notranslate"><span class="pre">while</span></code> conditions are available
outside the block (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4820">#4820</a>).</p></li>
<li><p>Local exported (<code class="docutils literal notranslate"><span class="pre">set</span> <span class="pre">-lx</span></code>) vars are now visible to functions
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1091">#1091</a>).</p></li>
<li><p>The new <code class="docutils literal notranslate"><span class="pre">math</span></code> builtin (see below) does not support logical
expressions; <code class="docutils literal notranslate"><span class="pre">test</span></code> should be used instead (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4777">#4777</a>).</p></li>
<li><p>Range expansion will now behave sensibly when given a single positive
and negative index (<code class="docutils literal notranslate"><span class="pre">$foo[5..-1]</span></code> or <code class="docutils literal notranslate"><span class="pre">$foo[-1..5]</span></code>), clamping to
the last valid index without changing direction if the list has fewer
elements than expected.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">read</span></code> now uses <code class="docutils literal notranslate"><span class="pre">-s</span></code> as short for <code class="docutils literal notranslate"><span class="pre">--silent</span></code> (à la <code class="docutils literal notranslate"><span class="pre">bash</span></code>);
<code class="docutils literal notranslate"><span class="pre">--shell</span></code>’s abbreviation (formerly <code class="docutils literal notranslate"><span class="pre">-s</span></code>) is now <code class="docutils literal notranslate"><span class="pre">-S</span></code> instead
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4490">#4490</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">cd</span></code> no longer resolves symlinks. fish now maintains a virtual
path, matching other shells (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3350">#3350</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">source</span></code> now requires an explicit <code class="docutils literal notranslate"><span class="pre">-</span></code> as the filename to read
from the terminal (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2633">#2633</a>).</p></li>
<li><p>Arguments to <code class="docutils literal notranslate"><span class="pre">end</span></code> are now errors, instead of being silently
ignored.</p></li>
<li><p>The names <code class="docutils literal notranslate"><span class="pre">argparse</span></code>, <code class="docutils literal notranslate"><span class="pre">read</span></code>, <code class="docutils literal notranslate"><span class="pre">set</span></code>, <code class="docutils literal notranslate"><span class="pre">status</span></code>, <code class="docutils literal notranslate"><span class="pre">test</span></code> and
<code class="docutils literal notranslate"><span class="pre">[</span></code> are now reserved and not allowed as function names. This
prevents users unintentionally breaking stuff (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3000">#3000</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_user_abbreviations</span></code> variable is no longer used;
abbreviations will be migrated to the new storage format
automatically.</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">FISH_READ_BYTE_LIMIT</span></code> variable is now called
<code class="docutils literal notranslate"><span class="pre">fish_byte_limit</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4414">#4414</a>).</p></li>
<li><p>Environment variables are no longer split into arrays based on the
record separator character on startup. Instead, variables are not
split, unless their name ends in PATH, in which case they are split
on colons (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/436">#436</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">history</span></code> builtin’s <code class="docutils literal notranslate"><span class="pre">--with-time</span></code> option has been removed;
this has been deprecated in favor of <code class="docutils literal notranslate"><span class="pre">--show-time</span></code> since 2.7.0
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4403">#4403</a>).</p></li>
<li><p>The internal variables <code class="docutils literal notranslate"><span class="pre">__fish_datadir</span></code> and <code class="docutils literal notranslate"><span class="pre">__fish_sysconfdir</span></code>
are now known as <code class="docutils literal notranslate"><span class="pre">__fish_data_dir</span></code> and <code class="docutils literal notranslate"><span class="pre">__fish_sysconf_dir</span></code>
respectively.</p></li>

<h3>Deprecations<a class="headerlink" href="#deprecations" title="Link to this heading">¶</a></h3>
<p>With the release of fish 3, a number of features have been marked for
removal in the future. All users are encouraged to explore alternatives.
A small number of these features are currently behind feature flags,
which are turned on at present but may be turned off by default in the
future.</p>
<p>A new feature flags mechanism is added for staging deprecations and
breaking changes. Feature flags may be specified at launch with
<code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--features</span> <span class="pre">...</span></code> or by setting the universal <code class="docutils literal notranslate"><span class="pre">fish_features</span></code>
variable. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4940">#4940</a>)</p>
<ul class="simple">
<li><p>The use of the <code class="docutils literal notranslate"><span class="pre">IFS</span></code> variable for <code class="docutils literal notranslate"><span class="pre">read</span></code> is deprecated; <code class="docutils literal notranslate"><span class="pre">IFS</span></code>
will be ignored in the future (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4156">#4156</a>). Use the <code class="docutils literal notranslate"><span class="pre">read</span> <span class="pre">--delimiter</span></code>
option instead.</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">function</span> <span class="pre">--on-process-exit</span></code> switch will be removed in future
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4700">#4700</a>). Use the <code class="docutils literal notranslate"><span class="pre">fish_exit</span></code> event instead:

<li><p><code class="docutils literal notranslate"><span class="pre">$_</span></code> is deprecated and will removed in the future (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/813">#813</a>). Use
<code class="docutils literal notranslate"><span class="pre">status</span> <span class="pre">current-command</span></code> in a command substitution instead.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">^</span></code> as a redirection deprecated and will be removed in the future.
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4394">#4394</a>). Use <code class="docutils literal notranslate"><span class="pre">2></span></code> to redirect stderr. This is controlled by the
<code class="docutils literal notranslate"><span class="pre">stderr-nocaret</span></code> feature flag.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">?</span></code> as a glob (wildcard) is deprecated and will be removed in the
future (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4520">#4520</a>). This is controlled by the <code class="docutils literal notranslate"><span class="pre">qmark-noglob</span></code> feature

<li><p>Variables may be used as commands (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/154">#154</a>).</p></li>
<li><p>fish may be started in private mode via <code class="docutils literal notranslate"><span class="pre">fish</span> <span class="pre">--private</span></code>. Private
mode fish sessions do not have access to the history file and any
commands evaluated in private mode are not persisted for future
sessions. A session variable <code class="docutils literal notranslate"><span class="pre">$fish_private_mode</span></code> can be queried to
detect private mode and adjust the behavior of scripts accordingly to
respect the user’s wish for privacy.</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">wait</span></code> command for waiting on backgrounded processes (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4498">#4498</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">math</span></code> is now a builtin rather than a wrapper around <code class="docutils literal notranslate"><span class="pre">bc</span></code>
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3157">#3157</a>). Floating point computations is now used by default, and can

<li><p>Setting <code class="docutils literal notranslate"><span class="pre">$PATH</span></code> no longer warns on non-existent directories,
allowing for a single $PATH to be shared across machines (eg via
dotfiles) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2969">#2969</a>).</p></li>

is larger than most operating systems’ argument size limit, so trying
to pass argument lists this size to external commands has never
worked.</p></li>
<li><p>The machine hostname, where available, is now exposed as the
<code class="docutils literal notranslate"><span class="pre">$hostname</span></code> reserved variable. This removes the dependency on the
<code class="docutils literal notranslate"><span class="pre">hostname</span></code> executable (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4422">#4422</a>).</p></li>

<ul class="simple">
<li><p>A pipe at the end of a line now allows the job to continue on the

<li><p>Italics and dim support out of the box on macOS for Terminal.app and

path (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4649">#4649</a>).</p></li>
<li><p>Pager navigation has been improved. Most notably, moving down now
wraps around, moving up from the commandline now jumps to the last
element and moving right and left now reverse each other even when
wrapping around (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4680">#4680</a>).</p></li>
<li><p>Typing normal characters while the completion pager is active no
longer shows the search field. Instead it enters them into the
command line, and ends paging (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2249">#2249</a>).</p></li>
<li><p>A new input binding <code class="docutils literal notranslate"><span class="pre">pager-toggle-search</span></code> toggles the search field
in the completions pager on and off. By default, this is bound to
Ctrl-S.</p></li>
<li><p>Searching in the pager now does a full fuzzy search (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5213">#5213</a>).</p></li>

line if the number of completions is large (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4702">#4702</a>).</p></li>
<li><p>Abbreviations can be tab-completed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3233">#3233</a>).</p></li>
<li><p>Tildes in file names are now properly escaped in completions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2274">#2274</a>).</p></li>
<li><p>Wrapping completions (from <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">--wraps</span></code> or

The <code class="docutils literal notranslate"><span class="pre">alias</span></code> function has been updated to respect this behavior.</p></li>
<li><p>Path completions now support expansions, meaning expressions like
<code class="docutils literal notranslate"><span class="pre">python</span> <span class="pre">~/<TAB></span></code> now provides file suggestions just like any other
relative or absolute path. (This includes support for other
expansions, too.)</p></li>
<li><p>Autosuggestions try to avoid arguments that are already present in
the command line.</p></li>

<h3>Other fixes and improvements<a class="headerlink" href="#other-fixes-and-improvements" title="Link to this heading">¶</a></h3>
<ul class="simple">

variables (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4200">#4200</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4341">#4341</a>), executing functions, globs (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4579">#4579</a>),
<code class="docutils literal notranslate"><span class="pre">string</span></code> reading from standard input (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4610">#4610</a>), and slicing history
(in particular, <code class="docutils literal notranslate"><span class="pre">$history[1]</span></code> for the last executed command).</p></li>
<li><p>Fish’s internal wcwidth function has been updated to deal with newer
Unicode, and the width of some characters can be configured via the
<code class="docutils literal notranslate"><span class="pre">fish_ambiguous_width</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/5149">#5149</a>) and <code class="docutils literal notranslate"><span class="pre">fish_emoji_width</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2652">#2652</a>)

can be used to use the system’s wcwidth instead (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4816">#4816</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">functions</span></code> correctly supports <code class="docutils literal notranslate"><span class="pre">-d</span></code> as the short form of

<li><p>Using a read-only variable in a <code class="docutils literal notranslate"><span class="pre">for</span></code> loop produces an error,
rather than silently producing incorrect results (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/4342">#4342</a>).</p></li>
<li><p>The universal variables filename no longer contains the hostname or

their exported status affected by local variables (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2611">#2611</a>).</p></li>

<li><p>A new <code class="docutils literal notranslate"><span class="pre">argparse</span></code> command is available to allow fish script to parse

<ul class="simple">
<li><p>Apple macOS Sierra 10.12.5 introduced a problem with launching web
browsers from other programs using AppleScript. This affects the fish
Web configuration (<code class="docutils literal notranslate"><span class="pre">fish_config</span></code>); users on these platforms will
need to manually open the address displayed in the terminal, such as
by copying and pasting it into a browser. This problem will be fixed
with macOS 10.12.6.</p></li>

<ul class="simple">
<li><p>Performance improvements in launching processes, including major
reductions in signal blocking. Although this has been heavily tested,
it may cause problems in some circumstances; set the
<code class="docutils literal notranslate"><span class="pre">FISH_NO_SIGNAL_BLOCK</span></code> variable to 0 in your fish configuration
file to return to the old behaviour (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2007">#2007</a>).</p></li>

<li><p><code class="docutils literal notranslate"><span class="pre">read</span></code> will read up to 10 MiB by default, leaving the target
variable empty and exiting with status 122 if the line is too long.
You can set a different limit with the <code class="docutils literal notranslate"><span class="pre">FISH_READ_BYTE_LIMIT</span></code>
variable.</p></li>

typed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/838">#838</a>), for when reading sensitive data from the terminal.
<code class="docutils literal notranslate"><span class="pre">read</span></code> also now accepts simple strings for the prompt (rather than

<li><p>Under terminals which support it, bracketed paste is enabled,
escaping problematic characters for security and convenience (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3871">#3871</a>).
Inside single quotes (<code class="docutils literal notranslate"><span class="pre">'</span></code>), single quotes and backslashes in pasted
text are escaped (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/967">#967</a>). The <code class="docutils literal notranslate"><span class="pre">fish_clipboard_paste</span></code> function (bound
to <code class="docutils literal notranslate"><span class="pre">C-v</span></code> by default) is still the recommended pasting method where

<li><p>Processes in pipelines are no longer signalled as soon as one command
in the pipeline has completed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1926">#1926</a>). This behaviour matches other
shells mre closely.</p></li>
<li><p>All functions requiring Python work with whichever version of Python
is installed (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3970">#3970</a>). Python 3 is preferred, but Python 2.6 remains
the minimum version required.</p></li>

<h2>fish 2.5b1 (released January 14, 2017)<a class="headerlink" href="#fish-2-5b1-released-january-14-2017" title="Link to this heading">¶</a></h2>
<section id="platform-changes">
<h3>Platform Changes<a class="headerlink" href="#platform-changes" title="Link to this heading">¶</a></h3>
<p>Starting with version 2.5, fish requires a more up-to-date version of
C++, specifically C++11 (from 2011). This affects some older platforms:</p>
<section id="linux">
<h4>Linux<a class="headerlink" href="#linux" title="Link to this heading">¶</a></h4>
<p>For users building from source, GCC’s g++ 4.8 or later, or LLVM’s clang
3.3 or later, are known to work. Older platforms may require a newer
compiler installed.</p>
<p>Unfortunately, because of the complexity of the toolchain, binary
packages are no longer published by the fish-shell developers for the
following platforms:</p>
<ul class="simple">
<li><p>Red Hat Enterprise Linux and CentOS 5 & 6 for 64-bit builds</p></li>
<li><p>Ubuntu 12.04 (EoLTS April 2017)</p></li>
<li><p>Debian 7 (EoLTS May 2018)</p></li>
</ul>
<p>Installing newer version of fish on these systems will require building
from source.</p>
</section>
<section id="os-x-snowleopard">
<h4>OS X SnowLeopard<a class="headerlink" href="#os-x-snowleopard" title="Link to this heading">¶</a></h4>
<p>Starting with version 2.5, fish requires a C++11 standard library on OS
X 10.6 (“SnowLeopard”). If this library is not installed, you will see
this error: <code class="docutils literal notranslate"><span class="pre">dyld:</span> <span class="pre">Library</span> <span class="pre">not</span> <span class="pre">loaded:</span> <span class="pre">/usr/lib/libc++.1.dylib</span></code></p>
<p>MacPorts is the easiest way to obtain this library. After installing the
SnowLeopard MacPorts release from the install page, run:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="nf">sudo</span><span class="w"> </span><span class="no">port</span><span class="w"> </span><span class="no">-v</span><span class="w"> </span><span class="no">install</span><span class="w"> </span><span class="no">libcxx</span>
</pre></div>
</div>
<p>Now fish should launch successfully. (Please open an issue if it does
not.)</p>
<p>This is only necessary on 10.6. OS X 10.7 and later include the required
library by default.</p>

<span id="id91"></span><h3>Other significant changes<a class="headerlink" href="#other-significant-changes-2" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>Attempting to exit with running processes in the background produces
a warning, then signals them to terminate if a second attempt to exit
is made. This brings the behaviour for running background processes
into line with stopped processes. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3497">#3497</a>)</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">random</span></code> can now have start, stop and step values specified, or the
new <code class="docutils literal notranslate"><span class="pre">choice</span></code> subcommand can be used to pick an argument from a list
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3619">#3619</a>).</p></li>
<li><p>A new key bindings preset, <code class="docutils literal notranslate"><span class="pre">fish_hybrid_key_bindings</span></code>, including
all the Emacs-style and Vi-style bindings, which behaves like
<code class="docutils literal notranslate"><span class="pre">fish_vi_key_bindings</span></code> in fish 2.3.0 (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3556">#3556</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">function</span></code> now returns an error when called with invalid options,
rather than defining the function anyway (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3574">#3574</a>). This was a
regression present in fish 2.3 and 2.4.0.</p></li>
<li><p>fish no longer prints a warning when it identifies a running instance
of an old version (2.1.0 and earlier). Changes to universal variables
may not propagate between these old versions and 2.5b1.</p></li>
<li><p>Improved compatibility with Android (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3585">#3585</a>), MSYS/mingw (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2360">#2360</a>), and
Solaris (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3456">#3456</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3340">#3340</a>).</p></li>
<li><p>Like other shells, the <code class="docutils literal notranslate"><span class="pre">test</span></code> built-in now returns an error for
numeric operations on invalid integers (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3346">#3346</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3581">#3581</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">complete</span></code> no longer recognises <code class="docutils literal notranslate"><span class="pre">--authoritative</span></code> and
<code class="docutils literal notranslate"><span class="pre">--unauthoritative</span></code> options, and they are marked as obsolete.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">status</span></code> accepts subcommands, and should be used like
<code class="docutils literal notranslate"><span class="pre">status</span> <span class="pre">is-interactive</span></code>. The old options continue to be supported
for the foreseeable future (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3526">#3526</a>), although only one subcommand or
option can be specified at a time.</p></li>
<li><p>Selection mode (used with “begin-selection”) no longer selects a
character the cursor does not move over (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3684">#3684</a>).</p></li>
<li><p>List indexes are handled better, and a bit more liberally in some
cases (<code class="docutils literal notranslate"><span class="pre">echo</span> <span class="pre">$PATH[1</span> <span class="pre">..</span> <span class="pre">3]</span></code> is now valid) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3579">#3579</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_mode_prompt</span></code> function is now simply a stub around
<code class="docutils literal notranslate"><span class="pre">fish_default_mode_prompt</span></code>, which allows the mode prompt to be
included more easily in customised prompt functions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3641">#3641</a>).</p></li>

<ul class="simple">

aliases, and aliases now include a description in the function
signature that identifies them.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">complete</span></code> accepts empty strings as descriptions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3557">#3557</a>).</p></li>

<li><p>The <code class="docutils literal notranslate"><span class="pre">$status</span></code> variable is now set to 123 when a syntactically
invalid command is entered (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3616">#3616</a>).</p></li>
<li><p>Exiting fish now signals all background processes to terminate, not
just stopped jobs (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3497">#3497</a>).</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">prompt_hostname</span></code> function which prints a hostname suitable
for use in prompts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3482">#3482</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">__fish_man_page</span></code> function (bound to Alt-h by default) now
tries to recognize subcommands (e.g. <code class="docutils literal notranslate"><span class="pre">git</span> <span class="pre">add</span></code> will now open the
“git-add” man page) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3678">#3678</a>).</p></li>
<li><p>A new function <code class="docutils literal notranslate"><span class="pre">edit_command_buffer</span></code> (bound to Alt-e & Alt-v by

and reverse (<code class="docutils literal notranslate"><span class="pre">--reverse</span></code>) modes (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3650">#3650</a>).</p></li>

will no longer slow fish down (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/685">#685</a>).</p></li>

<ul class="simple">
<li><p>The clipboard integration has been revamped with explicit bindings.
The killring commands no longer copy from, or paste to, the X11
clipboard - use the new copy (<code class="docutils literal notranslate"><span class="pre">C-x</span></code>) and paste (<code class="docutils literal notranslate"><span class="pre">C-v</span></code>) bindings
instead. The clipboard is now available on OS X as well as systems
using X11 (e.g. Linux). (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3061">#3061</a>)</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">history</span></code> uses subcommands (<code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">delete</span></code>) rather than options
(<code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">--delete</span></code>) for its actions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3367">#3367</a>). You can no longer
specify multiple actions via flags (e.g.,
<code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">--delete</span> <span class="pre">--save</span> <span class="pre">something</span></code>).</p></li>
<li><p>New <code class="docutils literal notranslate"><span class="pre">history</span></code> options have been added, including <code class="docutils literal notranslate"><span class="pre">--max=n</span></code> to
limit the number of history entries, <code class="docutils literal notranslate"><span class="pre">--show-time</span></code> option to show
timestamps (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3175">#3175</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3244">#3244</a>), and <code class="docutils literal notranslate"><span class="pre">--null</span></code> to null terminate history
entries in the search output.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">search</span></code> is now case-insensitive by default (which also
affects <code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">delete</span></code>) (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3236">#3236</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">delete</span></code> now correctly handles multiline commands (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/31">#31</a>).</p></li>
<li><p>Vi-style bindings no longer include all of the default emacs-style
bindings; instead, they share some definitions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3068">#3068</a>).</p></li>
<li><p>If there is no locale set in the environment, various known system
configuration files will be checked for a default. If no locale can
be found, <code class="docutils literal notranslate"><span class="pre">en_US-UTF.8</span></code> will be used (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/277">#277</a>).</p></li>
<li><p>A number followed by a caret (e.g. <code class="docutils literal notranslate"><span class="pre">5^</span></code>) is no longer treated as a
redirection (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1873">#1873</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">$version</span></code> special variable can be overwritten, so that it can
be used for other purposes if required.</p></li>

<span id="id94"></span><h3>Notable fixes and improvements<a class="headerlink" href="#notable-fixes-and-improvements-5" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>The <code class="docutils literal notranslate"><span class="pre">fish_realpath</span></code> builtin has been renamed to <code class="docutils literal notranslate"><span class="pre">realpath</span></code> and
made compatible with GNU <code class="docutils literal notranslate"><span class="pre">realpath</span></code> when run without arguments
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3400">#3400</a>). It is used only for systems without a <code class="docutils literal notranslate"><span class="pre">realpath</span></code> or
<code class="docutils literal notranslate"><span class="pre">grealpath</span></code> utility (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3374">#3374</a>).</p></li>
<li><p>Improved color handling on terminals/consoles with 8-16 colors,
particularly the use of bright named color (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3176">#3176</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3260">#3260</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_indent</span></code> can now read from files given as arguments, rather
than just standard input (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3037">#3037</a>).</p></li>
<li><p>Fuzzy tab completions behave in a less surprising manner (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3090">#3090</a>,
<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3211">#3211</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">jobs</span></code> should only print its header line once (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3127">#3127</a>).</p></li>
<li><p>Wildcards in redirections are highlighted appropriately (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2789">#2789</a>).</p></li>
<li><p>Suggestions will be offered more often, like after removing
characters (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3069">#3069</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">history</span> <span class="pre">--merge</span></code> now correctly interleaves items in chronological
order (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2312">#2312</a>).</p></li>
<li><p>Options for <code class="docutils literal notranslate"><span class="pre">fish_indent</span></code> have been aligned with the other binaries
- in particular, <code class="docutils literal notranslate"><span class="pre">-d</span></code> now means <code class="docutils literal notranslate"><span class="pre">--debug</span></code>. The <code class="docutils literal notranslate"><span class="pre">--dump</span></code> option
has been renamed to <code class="docutils literal notranslate"><span class="pre">--dump-parse-tree</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3191">#3191</a>).</p></li>
<li><p>The display of bindings in the Web-based configuration has been
greatly improved (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3325">#3325</a>), as has the rendering of prompts (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2924">#2924</a>).</p></li>
<li><p>fish should no longer hang using 100% CPU in the C locale (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3214">#3214</a>).</p></li>
<li><p>A bug in FreeBSD 11 & 12, Dragonfly BSD & illumos prevented fish from
working correctly on these platforms under UTF-8 locales; fish now
avoids the buggy behaviour (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3050">#3050</a>).</p></li>
<li><p>Prompts which show git repository information (via
<code class="docutils literal notranslate"><span class="pre">__fish_git_prompt</span></code>) are faster in large repositories (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3294">#3294</a>) and
slow filesystems (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3083">#3083</a>).</p></li>
<li><p>fish 2.3.0 reintroduced a problem where the greeting was printed even
when using <code class="docutils literal notranslate"><span class="pre">read</span></code>; this has been corrected again (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3261">#3261</a>).</p></li>
<li><p>Vi mode changes the cursor depending on the current mode (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/3215">#3215</a>).</p></li>
<li><p>Command lines with escaped space characters at the end tab-complete
correctly (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2447">#2447</a>).</p></li>
<li><p>Added completions for:</p>

<span id="id100"></span><h3>Significant Changes<a class="headerlink" href="#significant-changes-3" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>A new <code class="docutils literal notranslate"><span class="pre">string</span></code> builtin to handle… strings! This builtin will
measure, split, search and replace text strings, including using
regular expressions. It can also be used to turn lists into plain
strings using <code class="docutils literal notranslate"><span class="pre">join</span></code>. <code class="docutils literal notranslate"><span class="pre">string</span></code> can be used in place of <code class="docutils literal notranslate"><span class="pre">sed</span></code>,
<code class="docutils literal notranslate"><span class="pre">grep</span></code>, <code class="docutils literal notranslate"><span class="pre">tr</span></code>, <code class="docutils literal notranslate"><span class="pre">cut</span></code>, and <code class="docutils literal notranslate"><span class="pre">awk</span></code> in many situations. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2296">#2296</a>)</p></li>
<li><p>Allow using escape as the Meta modifier key, by waiting after seeing
an escape character wait up to 300ms for an additional character.
This is consistent with readline (e.g. bash) and can be configured
via the <code class="docutils literal notranslate"><span class="pre">fish_escape_delay_ms</span> <span class="pre">variable</span></code>. This allows using escape
as the Meta modifier. (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1356">#1356</a>)</p></li>
<li><p>Add new directories for vendor functions and configuration snippets
(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/2500">#2500</a>)</p></li>
<li><p>A new <code class="docutils literal notranslate"><span class="pre">fish_realpath</span></code> builtin and associated <code class="docutils literal notranslate"><span class="pre">realpath</span></code> function
should allow scripts to resolve path names via <code class="docutils literal notranslate"><span class="pre">realpath</span></code>
regardless of whether there is an external command of that name;
albeit with some limitations. See the associated documentation.</p></li>

existing scripts.</p>
<ul class="simple">

<ul class="simple">
<li><p>New documentation design (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1662">#1662</a>), which requires a Doxygen version
1.8.7 or newer to build.</p></li>
<li><p>Fish now defines a default directory for other packages to provide
completions. By default this is
<code class="docutils literal notranslate"><span class="pre">/usr/share/fish/vendor-completions.d</span></code>; on systems with
<code class="docutils literal notranslate"><span class="pre">pkgconfig</span></code> installed this path is discoverable with

proceed and the wildcard will expand to zero arguments (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1482">#1482</a>).</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">.</span></code> command is deprecated and the <code class="docutils literal notranslate"><span class="pre">source</span></code> command is

(recursively) inherit the completions of a wrapped command (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/393">#393</a>),
and <code class="docutils literal notranslate"><span class="pre">complete</span> <span class="pre">-e</span></code> now correctly erases completions (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/380">#380</a>).</p></li>

(<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1063">#1063</a>).</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fish_title</span></code> functions have access to the arguments of the
currently running argument as <code class="docutils literal notranslate"><span class="pre">$argv[1]</span></code> (<a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1542">#1542</a>).</p></li>

<h2>fish 2.1.2 (released Feb 24, 2015)<a class="headerlink" href="#fish-2-1-2-released-feb-24-2015" title="Link to this heading">¶</a></h2>
<p>fish 2.1.2 contains a workaround for a filesystem bug in Mac OS X
Yosemite. <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1859">#1859</a></p>
<p>Specifically, after installing fish 2.1.1 and then rebooting, “Verify
Disk” in Disk Utility will report “Invalid number of hard links.” We
don’t have any reports of data loss or other adverse consequences. fish
2.1.2 avoids triggering the bug, but does not repair an already affected
filesystem. To repair the filesystem, you can boot into Recovery Mode
and use Repair Disk from Disk Utility. Linux and versions of OS X prior
to Yosemite are believed to be unaffected.</p>
<p>There are no other changes in this release.</p>

<section id="significant-changes-5">
<span id="id105"></span><h3>Significant Changes<a class="headerlink" href="#significant-changes-5" title="Link to this heading">¶</a></h3>
<ul>
<li><p><strong>Tab completions will fuzzy-match files.</strong> <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/568">#568</a></p>
<p>When tab-completing a file, fish will first attempt prefix matches
(<code class="docutils literal notranslate"><span class="pre">foo</span></code> matches <code class="docutils literal notranslate"><span class="pre">foobar</span></code>), then substring matches (<code class="docutils literal notranslate"><span class="pre">ooba</span></code>
matches <code class="docutils literal notranslate"><span class="pre">foobar</span></code>), and lastly subsequence matches (<code class="docutils literal notranslate"><span class="pre">fbr</span></code> matches
<code class="docutils literal notranslate"><span class="pre">foobar</span></code>). For example, in a directory with files foo1.txt,
foo2.txt, foo3.txt…, you can type only the numeric part and hit tab
to fill in the rest.</p>
<p>This feature is implemented for files and executables. It is not yet
implemented for options (like <code class="docutils literal notranslate"><span class="pre">--foobar</span></code>), and not yet implemented
across path components (like <code class="docutils literal notranslate"><span class="pre">/u/l/b</span></code> to match <code class="docutils literal notranslate"><span class="pre">/usr/local/bin</span></code>).</p>
</li>
<li><p><strong>Redirections now work better across pipelines.</strong> <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/110">#110</a>, <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/877">#877</a></p>
<p>In particular, you can pipe stderr and stdout together, for example,
with <code class="docutils literal notranslate"><span class="pre">cmd</span> <span class="pre">^&1</span> <span class="pre">|</span> <span class="pre">tee</span> <span class="pre">log.txt</span></code>, or the more familiar
<code class="docutils literal notranslate"><span class="pre">cmd</span> <span class="pre">2>&1</span> <span class="pre">|</span> <span class="pre">tee</span> <span class="pre">log.txt</span></code>.</p>
</li>
<li><p><strong>A single ``%`` now expands to the last job backgrounded.</strong> <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/1008">#1008</a></p>
<p>Previously, a single <code class="docutils literal notranslate"><span class="pre">%</span></code> would pid-expand to either all
backgrounded jobs, or all jobs owned by your user. Now it expands to
the last job backgrounded. If no job is in the background, it will
fail to expand. In particular, <code class="docutils literal notranslate"><span class="pre">fg</span> <span class="pre">%</span></code> can be used to put the most
recent background job in the foreground.</p>

<li><p>Option-right-arrow (used for partial autosuggestion completion) now

<ul>
<li><p><strong>Command substitutions now modify ``$status`` :issue:`547`.</strong> Previously the
exit status of command substitutions (like <code class="docutils literal notranslate"><span class="pre">(pwd)</span></code>) was ignored;
however now it modifies $status. Furthermore, the <code class="docutils literal notranslate"><span class="pre">set</span></code> command now
only sets $status on failure; it is untouched on success. This allows
for the following pattern:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span><span class="k">if</span><span class="w"> </span><span class="nb">set</span><span class="w"> </span>python_path<span class="w"> </span><span class="o">(</span>which<span class="w"> </span>python<span class="o">)</span>
<span class="w"> </span>...
end
</pre></div>
</div>
<p>Because set does not modify $status on success, the if branch
effectively tests whether <code class="docutils literal notranslate"><span class="pre">which</span></code> succeeded, and if so, whether the
<code class="docutils literal notranslate"><span class="pre">set</span></code> also succeeded.</p>
</li>
<li><p>Improvements to PATH handling. There is a new variable, fish_user_paths,

<h3>Bug Fixes<a class="headerlink" href="#bug-fixes" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p><strong>Implicit cd</strong> is back, for paths that start with one or two dots, a
slash, or a tilde.</p></li>
<li><p><strong>Overrides of default functions should be fixed.</strong> The “internalized
scripts” feature is disabled for now.</p></li>
<li><p><strong>Disabled delayed suspend.</strong> This is a strange job-control feature
of BSD systems, including OS X. Disabling it frees up Control Y for
other purposes; in particular, for yank, which now works on OS X.</p></li>
<li><p><strong>fish_indent is fixed.</strong> In particular, the <code class="docutils literal notranslate"><span class="pre">funced</span></code> and
<code class="docutils literal notranslate"><span class="pre">funcsave</span></code> functions work again.</p></li>
<li><p>A SIGTERM now ends the whole execution stack again (resolving <a class="reference external" href="https://github.com/fish-shell/fish-shell/issues/13">#13</a>).</p></li>
<li><p>Bumped the __fish_config_interactive version number so the default

<li><p>fish_config better handles combined term256 and classic colors like
“555 yellow”.</p></li>

<section id="scripting">
<h3>Scripting<a class="headerlink" href="#scripting" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>No changes! All existing fish scripts, config files, completions,
etc. from trunk should continue to work.</p></li>
</ul>
</section>
<section id="new-features-1">
<span id="id108"></span><h3>New Features<a class="headerlink" href="#new-features-1" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p><strong>Autosuggestions</strong>. Think URL fields in browsers. When you type a
command, fish will suggest the rest of the command after the cursor,
in a muted gray when possible. You can accept the suggestion with the
right arrow key or Ctrl-F. Suggestions come from command history,
completions, and some custom code for cd; there’s a lot of potential
for improvement here. The suggestions are computed on a background
pthread, so they never slow down your typing. The autosuggestion
feature is incredible. I miss it dearly every time I use anything
else.</p></li>
<li><p><strong>term256 support</strong> where available, specifically modern xterms and
OS X Lion. You can specify colors the old way (‘set_color cyan’) or
by specifying RGB hex values (‘set_color FF3333’); fish will pick the
closest supported color. Some xterms do not advertise term256 support
either in the $TERM or terminfo max_colors field, but nevertheless
support it. For that reason, fish will default into using it on any
xterm (but it can be disabled with an environment variable).</p></li>
<li><p><strong>Web-based configuration</strong> page. There is a new function
‘fish_config’. This spins up a simple Python web server and opens a
browser window to it. From this web page, you can set your shell
colors and view your functions, variables, and history; all changes
apply immediately to all running shells. Eventually all configuration
ought to be supported via this mechanism (but in addition to, not
instead of, command line mechanisms).</p></li>
<li><p><strong>Man page completions</strong>. There is a new function
‘fish_update_completions’. This function reads all the man1 files
from your manpath, removes the roff formatting, parses them to find
the commands and options, and outputs fish completions into
~/.config/fish/completions. It won’t overwrite existing completion
files (except ones that it generated itself).</p></li>
</ul>
</section>
<section id="programmatic-changes">
<h3>Programmatic Changes<a class="headerlink" href="#programmatic-changes" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>fish is now entirely in C++. I have no particular love for C++, but
it provides a ready memory-model to replace halloc. We’ve made an
effort to keep it to a sane and portable subset (no C++11, no boost,
no going crazy with templates or smart pointers), but we do use the
STL and a little tr1.</p></li>
<li><p>halloc is entirely gone, replaced by normal C++ ownership semantics.
If you don’t know what halloc is, well, now you have two reasons to
be happy.</p></li>
<li><p>All the crufty C data structures are entirely gone. array_list_t,
priority_queue_t, hash_table_t, string_buffer_t have been removed and
replaced by STL equivalents like std::vector, std::map, and
std::wstring. A lot of the string handling now uses std::wstring
instead of wchar_t *</p></li>
<li><p>fish now spawns pthreads for tasks like syntax highlighting that
require blocking I/O.</p></li>
<li><p>History has been completely rewritten. History files now use an
extensible YAML-style syntax. History “merging” (multiple shells
writing to the same history file) now works better. There is now a
maximum history length of about 250k items (256 * 1024).</p></li>
<li><p>The parser has been “instanced,” so you can now create more than one.</p></li>
<li><p>Total #LoC has shrunk slightly even with the new features.</p></li>
</ul>
</section>
<section id="performance">
<h3>Performance<a class="headerlink" href="#performance" title="Link to this heading">¶</a></h3>
<ul class="simple">
<li><p>fish now runs syntax highlighting in a background thread, so typing
commands is always responsive even on slow filesystems.</p></li>
<li><p>echo, test, and pwd are now builtins, which eliminates many forks.</p></li>
<li><p>The files in share/functions and share/completions now get
‘internalized’ into C strings that get compiled in with fish. This
substantially reduces the number of files touched at startup. A
consequence is that you cannot change these functions without
recompiling, but often other functions depend on these “standard”
functions, so changing them is perhaps not a good idea anyways.</p></li>
</ul>
<p>Here are some system call counts for launching and then exiting fish
with the default configuration, on OS X. The first column is fish trunk,
the next column is with our changes, and the last column is bash for
comparison. This data was collected via dtrace.</p>
<table><tr><th><th><p>before</p>
<th><p>after</p>
<th><p>bash</p>
<tr><th><p>open</p>
<td><p>9</p>
<td><p>4</p>
<td><p>5</p>
<tr><th><p>fork</p>
<td><p>28</p>
<td><p>14</p>
<td><p>0</p>
<tr><th><p>stat</p>
<td><p>131</p>
<td><p>85</p>
<td><p>11</p>
<tr><th><p>lstat</p>
<td><p>670</p>
<td><p>0</p>
<td><p>0</p>
<tr><th><p>read</p>
<td><p>332</p>
<td><p>80</p>
<td><p>4</p>
<tr><th><p>write</p>
<td><p>172</p>
<td><p>149</p>
<td><p>0</p>
</table><p>The large number of forks relative to bash are due to fish’s insanely
expensive default prompt, which is unchanged in my version. If we switch
to a prompt comparable to bash’s (lame) default, the forks drop to 16
with trunk, 4 after our changes.</p>
<p>The large reduction in lstat() numbers is due to fish no longer needing
to call ttyname() on OS X.</p>
<p>We’ve got some work to do to be as lean as bash, but we’re on the right
track.</p>
