|
<p>To override global configuration parameters, create a <code>config.toml</code> file located in your config directory:</p>
|
|
<ul>
|
|
<li>Linux and Mac: <code>~/.config/helix/config.toml</code></li>
|
|
<li>Windows: <code>%AppData%\helix\config.toml</code></li>
|
|
</ul>
|
|
<blockquote>
|
|
<p>💡 You can easily open the config file by typing <code>:config-open</code> within Helix normal mode.</p>
|
|
</blockquote>
|
|
<p>Example config:</p>
|
|
<pre><code class="language-toml">theme = "onedark"
|
|
|
|
[editor]
|
|
line-number = "relative"
|
|
mouse = false
|
|
|
|
[editor.cursor-shape]
|
|
insert = "bar"
|
|
normal = "block"
|
|
select = "underline"
|
|
|
|
[editor.file-picker]
|
|
hidden = false
|
|
</code></pre>
|
|
<p>You can use a custom configuration file by specifying it with the <code>-c</code> or
|
|
<code>--config</code> command line argument, for example <code>hx -c path/to/custom-config.toml</code>.
|
|
Additionally, you can reload the configuration file by sending the USR1
|
|
signal to the Helix process on Unix operating systems, such as by using the command <code>pkill -USR1 hx</code>.</p>
