<p>We provide pre-built binaries on the <a href="https://github.com/helix-editor/helix/releases">GitHub Releases page</a>.</p>

<h2 id="osx"><a class="header" href="#osx">OSX</a></h2>
|
|
<p>A Homebrew tap is available:</p>
|
|
<pre><code>brew tap helix-editor/helix
|
|
brew install helix
|
|
</code></pre>
|

<h2 id="linux"><a class="header" href="#linux">Linux</a></h2>

|
<h3 id="nixos"><a class="header" href="#nixos">NixOS</a></h3>
|
|
<p>A <a href="https://nixos.wiki/wiki/Flakes">flake</a> containing the package is available in
|
|
the project root. The flake can also be used to spin up a reproducible development
|
|
shell for working on Helix.</p>
|
|
<h3 id="arch-linux"><a class="header" href="#arch-linux">Arch Linux</a></h3>
|
|
<p>Binary packages are available on AUR:</p>
|
|
<ul>
|
|
<li><a href="https://aur.archlinux.org/packages/helix-bin/">helix-bin</a> contains the pre-built release</li>
|
|
<li><a href="https://aur.archlinux.org/packages/helix-git/">helix-git</a> builds the master branch</li>
|
|
</ul>
|

<h2 id="build-from-source"><a class="header" href="#build-from-source">Build from source</a></h2>
|
|
<pre><code>git clone --recurse-submodules --shallow-submodules -j8 https://github.com/helix-editor/helix
|
|
cd helix
|
|
cargo install --path helix-term
|
|
</code></pre>
|
|
<p>This will install the <code>hx</code> binary to <code>$HOME/.cargo/bin</code>.</p>
|
|
<p>Now copy the <code>runtime/</code> directory somewhere. Helix will by default look for the
|
|
runtime inside the same folder as the executable, but that can be overriden via
|
|
the <code>HELIX_RUNTIME</code> environment variable.</p>
|
|
<p>If you want to embed the <code>runtime/</code> directory into the Helix binary you can build
|
|
it with:</p>
|
|
<pre><code>cargo install --path helix-term --features "embed_runtime"
|
|
</code></pre>

<h2 id="surround"><a class="header" href="#surround">Surround</a></h2>
|
|
<p>Functionality similar to <a href="https://github.com/tpope/vim-surround">vim-surround</a> is built into
|
|
helix. The keymappings have been inspired from <a href="https://github.com/machakann/vim-sandwich">vim-sandwich</a>:</p>

<p><img src="https://user-images.githubusercontent.com/23398472/122865801-97073180-d344-11eb-8142-8f43809982c6.gif" alt="surround demo" /></p>
|
|
<ul>
|
|
<li><code>ms</code> - Add surround characters</li>
|
|
<li><code>mr</code> - Replace surround characters</li>
|
|
<li><code>md</code> - Delete surround characters</li>
|
|
</ul>
|
|
<p><code>ms</code> acts on a selection, so select the text first and use <code>ms<char></code>. <code>mr</code> and <code>md</code> work
|
|
on the closest pairs found and selections are not required; use counts to act in outer pairs.</p>
|
|
<p>It can also act on multiple seletions (yay!). For example, to change every occurance of <code>(use)</code> to <code>[use]</code>:</p>
|
|
<ul>
|
|
<li><code>%</code> to select the whole file</li>
|
|
<li><code>s</code> to split the selections on a search term</li>
|
|
<li>Input <code>use</code> and hit Enter</li>
|
|
<li><code>mr([</code> to replace the parens with square brackets</li>
|
|
</ul>
|
|
<p>Multiple characters are currently not supported, but planned.</p>

<div style="break-before: page; page-break-before: always;"></div><h1 id="configuration"><a class="header" href="#configuration">Configuration</a></h1>
|
|
<p>To override global configuration parameters create a <code>config.toml</code> file located in your config directory (i.e <code>~/.config/helix/config.toml</code>).</p>
|
|
<h2 id="lsp"><a class="header" href="#lsp">LSP</a></h2>
|
|
<p>To display all language server messages in the status line add the following to your <code>config.toml</code>:</p>
|
|
<pre><code class="language-toml">[lsp]
|
|
display-messages = true
|
|
</code></pre>
|
|
<div style="break-before: page; page-break-before: always;"></div><h1 id="themes"><a class="header" href="#themes">Themes</a></h1>
|
|
<p>First you'll need to place selected themes in your <code>themes</code> directory (i.e <code>~/.config/helix/themes</code>), the directory might have to be created beforehand.</p>
|
|
<p>To use a custom theme add <code>theme = <name></code> to your <a href="./configuration.html"><code>config.toml</code></a> or override it during runtime using <code>:theme <name></code>.</p>
|
|
<p>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/runtime/themes">here</a>. </p>
|
|
<h2 id="creating-a-theme"><a class="header" href="#creating-a-theme">Creating a theme</a></h2>
|
|
<p>First create a file with the name of your theme as file name (i.e <code>mytheme.toml</code>) and place it in your <code>themes</code> directory (i.e <code>~/.config/helix/themes</code>).</p>
|
|
<p>Each line in the theme file is specified as below:</p>
|
|
<pre><code class="language-toml">key = { fg = "#ffffff", bg = "#000000", modifiers = ["bold", "italic"] }
|
|
</code></pre>
|
|
<p>where <code>key</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>
|
|
<h2 id="color-palettes"><a class="header" href="#color-palettes">Color palettes</a></h2>
|
|
<p>You can define a palette of named colors, and refer to them from the
|
|
configuration values in your theme. To do this, add a table called
|
|
<code>palette</code> to your theme file:</p>
|
|
<pre><code class="language-toml">ui.background = "white"
|
|
ui.text = "black"
|
|
|
|
[palette]
|
|
white = "#ffffff"
|
|
black = "#000000"
|
|
</code></pre>
|
|
<p>Remember that the <code>[palette]</code> table includes all keys after its header,
|
|
so you should define the palette after normal theme options.</p>

|
|
<p>One-way key remapping is temporarily supported via a simple TOML configuration
|
|
file. (More powerful solutions such as rebinding via commands will be
|
|
available in the feature).</p>
|
|
<p>To remap keys, write a <code>config.toml</code> file in your <code>helix</code> configuration
|
|
directory (default <code>~/.config/helix</code> in Linux systems) with a structure like
|
|
this:</p>
|
|
<pre><code class="language-toml"># At most one section each of 'keys.normal', 'keys.insert' and 'keys.select'
|
|
[keys.normal]
|
|
a = "move_char_left" # Maps the 'a' key to the move_char_left command
|
|
w = "move_line_up" # Maps the 'w' key move_line_up
|
|
C-S-esc = "extend_line" # Maps Control-Shift-Escape to extend_line
|
|
|
|
[keys.insert]
|
|
A-x = "normal_mode" # Maps Alt-X to enter normal mode
|
|
</code></pre>
|
|
<p>Control, Shift and Alt modifiers are encoded respectively with the prefixes
|

<code>C-</code>, <code>S-</code> and <code>A-</code>. Special keys are encoded as follows:</p>
