<p>To disable language server progress report from being displayed in the status bar add this option to your <code>config.toml</code>:</p>

<pre><code class="language-toml">lsp-progress = false

</code></pre>

<h2 id="theme"><a class="header" href="#theme">Theme</a></h2>
|
|
<p>Use a custom theme by placing a theme.toml in your config directory (i.e ~/.config/helix/theme.toml). The default theme.toml can be found <a href="https://github.com/helix-editor/helix/blob/master/theme.toml">here</a>, and user submitted themes <a href="https://github.com/helix-editor/helix/blob/master/contrib/themes">here</a>.</p>
|
|
<p>Styles in theme.toml are specified of in the form:</p>
|
|
<pre><code class="language-toml">key = { fg = "#ffffff", bg = "#000000", modifiers = ["bold", "italic"] }
|
|
</code></pre>
|
|
<p>where <code>name</code> represents what you want to style, <code>fg</code> specifies the foreground color, <code>bg</code> the background color, and <code>modifiers</code> is a list of style modifiers. <code>bg</code> and <code>modifiers</code> can be omitted to defer to the defaults.</p>
|
|
<p>To specify only the foreground color:</p>
|
|
<pre><code class="language-toml">key = "#ffffff"
|
|
</code></pre>
|
|
<p>if the key contains a dot <code>'.'</code>, it must be quoted to prevent it being parsed as a <a href="https://toml.io/en/v1.0.0#keys">dotted key</a>.</p>
|
|
<pre><code class="language-toml">"key.key" = "#ffffff"
|

<p>These keys match <a href="https://tree-sitter.github.io/tree-sitter/syntax-highlighting#theme">tree-sitter scopes</a>. We half-follow the common scopes from <a href="https://macromates.com/manual/en/language_grammars">macromates language grammars</a> with some differences.</p>
|
|
<p>For a given highlight produced, styling will be determined based on the longest matching theme key. So it's enough to provide function to highlight <code>function.macro</code> and <code>function.builtin</code> as well, but you can use more specific scopes to highlight specific cases differently.</p>
