<p><code class="docutils literal notranslate"><span class="pre">funced</span></code> provides an interface to edit the definition of the function <em>NAME</em>.</p>
<p>If the <code class="docutils literal notranslate"><span class="pre">$VISUAL</span></code> environment variable is set, it will be used as the program to edit the function. If <code class="docutils literal notranslate"><span class="pre">$VISUAL</span></code> is unset but <code class="docutils literal notranslate"><span class="pre">$EDITOR</span></code> is set, that will be used. Otherwise, a built-in editor will be used. Note that to enter a literal newline using the built-in editor you should press <kbd class="kbd docutils literal notranslate">alt</kbd>-<kbd class="kbd docutils literal notranslate">enter</kbd>. Pressing <kbd class="kbd docutils literal notranslate">enter</kbd> signals that you are done editing the function. This does not apply to an external editor like emacs or vim.</p>
<p><code class="docutils literal notranslate"><span class="pre">funced</span></code> will try to edit the original file that a function is defined in, which might include variable definitions or helper functions as well. If changes cannot be saved to the original file, a copy will be created in the user’s function directory.</p>
<p>If there is no function called <em>NAME</em>, a new function will be created with the specified name.</p>
<dl class="simple">
<dt><strong>-e command</strong> or <strong>--editor command</strong></dt><dd><p>Open the function body inside the text editor given by the command (for example, <strong>-e vi</strong>). The special command <code class="docutils literal notranslate"><span class="pre">fish</span></code> will use the built-in editor (same as specifying <strong>-i</strong>).</p>
</dd>
<dt><strong>-i</strong> or <strong>--interactive</strong></dt><dd><p>Force opening the function body in the built-in editor even if <code class="docutils literal notranslate"><span class="pre">$VISUAL</span></code> or <code class="docutils literal notranslate"><span class="pre">$EDITOR</span></code> is defined.</p>

<dt><strong>-s</strong> or <strong>--save</strong></dt><dd><p>Automatically save the function after successfully editing it.</p>
</dd>
<dt><strong>-h</strong> or <strong>--help</strong></dt><dd><p>Displays help about using this command.</p>
</dd>
</dl>
</section>
<section id="example">
<h2>Example<a class="headerlink" href="#example" title="Link to this heading">¶</a></h2>
<p>Say you want to modify your prompt.</p>
<p>Run:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="gp">>_ </span><span class="nf">funced</span><span class="w"> </span><span class="no">fish_prompt</span>
</pre></div>
</div>
<p>This will open up your editor, allowing you to modify the function. When you’re done, save and quit. Fish will reload the function, so you should see the changes right away.</p>
<p>When you’re done, use:</p>
<div class="highlight-fish-docs-samples notranslate"><div class="highlight"><pre><span></span><span class="gp">>_ </span><span class="nf">funcsave</span><span class="w"> </span><span class="no">fish_prompt</span>
</pre></div>
</div>
<p>For more, see <a class="reference internal" href="funcsave.html"><span class="doc">funcsave</span></a>. To view a function’s current definition, use <a class="reference internal" href="functions.html"><span class="doc">functions</span></a> or <a class="reference internal" href="type.html"><span class="doc">type</span></a>.</p>
