<p><code class="docutils literal notranslate"><span class="pre">_</span></code> translates its arguments into the current language, if possible.</p>
<p>This only works with messages which are translated as part of fish’s own sources, so using it as part of your own fish scripts which are not upstreamed into the fish repo will not work unless the exact same message also exists upstream.</p>
<p>It requires fish to be built with gettext support. If that support is disabled or there is no translation it will echo the argument back.</p>
<p>The language depends on the current locale, set with <span class="target" id="index-0"></span><a class="reference internal" href="../language.html#envvar-LANG"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">LANG</span></code></a>, <span class="target" id="index-1"></span><a class="reference internal" href="../language.html#envvar-LC_MESSAGES"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">LC_MESSAGES</span></code></a>, <span class="target" id="index-2"></span><a class="reference internal" href="../language.html#envvar-LC_ALL"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">LC_ALL</span></code></a>, and <span class="target" id="index-3"></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>.
These variables do not have to be exported for fish to use them, and fish’s variable scopes are supported.
If other programs launched via fish should respect these locale variables they have to be exported to make them available outside of fish.</p>
<p>For <span class="target" id="index-4"></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> you can use a list, or use colons to separate multiple languages.</p>
