<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>Releases are available in the <code>community</code> repository.</p>
<p>Packages are also 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>

<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>Helix also needs it's runtime files so make sure to copy/symlink the <code>runtime/</code> directory into the
config directory (for example <code>~/.config/helix/runtime</code> on Linux/macOS). This location can be overriden
via the <code>HELIX_RUNTIME</code> environment variable.</p>
<div style="break-before: page; page-break-before: always;"></div><h1 id="usage"><a class="header" href="#usage">Usage</a></h1>
<p>(Currently not fully documented, see the <a href="./keymap.html">keymappings</a> list for more.)</p>
<p>See <a href="https://github.com/helix-editor/helix/blob/master/runtime/tutor.txt">tutor.txt</a> (accessible via <code>hx --tutor</code> or <code>:tutor</code>) for a vimtutor-like introduction.</p>
<h2 id="registers"><a class="header" href="#registers">Registers</a></h2>
<p>Vim-like registers can be used to yank and store text to be pasted later. Usage is similar, with <code>&quot;</code> being used to select a register:</p>
<ul>
<li><code>&quot;ay</code> - Yank the current selection to register <code>a</code>.</li>
<li><code>&quot;op</code> - Paste the text in register <code>o</code> after the selection.</li>
</ul>
<p>If there is a selected register before invoking a change or delete command, the selection will be stored in the register and the action will be carried out:</p>
<ul>
<li><code>&quot;hc</code> - Store the selection in register <code>h</code> and then change it (delete and enter insert mode).</li>
<li><code>&quot;md</code> - Store the selection in register <code>m</code> and delete it.</li>
</ul>

<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&lt;char&gt;</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>
<h2 id="textobjects"><a class="header" href="#textobjects">Textobjects</a></h2>
<p>Currently supported: <code>word</code>, <code>surround</code>, <code>function</code>, <code>class</code>, <code>parameter</code>.</p>

<ul>
<li><code>ma</code> - Select around the object (<code>va</code> in vim, <code>&lt;alt-a&gt;</code> in kakoune)</li>
<li><code>mi</code> - Select inside the object (<code>vi</code> in vim, <code>&lt;alt-i&gt;</code> in kakoune)</li>

<tr><td><code>f</code></td><td>Function</td></tr>
<tr><td><code>c</code></td><td>Class</td></tr>

</tbody></table>
<p>Note: <code>f</code>, <code>c</code>, etc need a tree-sitter grammar active for the current
document and a special tree-sitter query file to work properly. <a href="https://github.com/search?q=repo%3Ahelix-editor%2Fhelix+filename%3Atextobjects.scm&amp;type=Code&amp;ref=advsearch&amp;l=&amp;l=">Only
some grammars</a>
currently have the query file implemented. Contributions are welcome !</p>
<div style="break-before: page; page-break-before: always;"></div><h1 id="migrating-from-vim"><a class="header" href="#migrating-from-vim">Migrating from Vim</a></h1>
<p>Helix's editing model is strongly inspired from vim and kakoune, and a notable
difference from vim (and the most striking similarity to kakoune) is that Helix
follows the <code>selection → action</code> model. This means that the whatever you are
going to act on (a word, a paragraph, a line, etc) is selected first and the
action itself (delete, change, yank, etc) comes second. A cursor is simply a
single width selection.</p>
<p>See also Kakoune's <a href="https://github.com/mawww/kakoune/wiki/Migrating-from-Vim">Migrating from Vim</a>.</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 = &lt;name&gt;</code> to your <a href="./configuration.html"><code>config.toml</code></a> or override it during runtime using <code>:theme &lt;name&gt;</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 = &quot;#ffffff&quot;, bg = &quot;#000000&quot;, modifiers = [&quot;bold&quot;, &quot;italic&quot;] }
</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 = &quot;#ffffff&quot;
</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">&quot;key.key&quot; = &quot;#ffffff&quot;
</code></pre>
<h3 id="color-palettes"><a class="header" href="#color-palettes">Color palettes</a></h3>
<p>It's recommended 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 = &quot;white&quot;
ui.text = &quot;black&quot;
[palette]
white = &quot;#ffffff&quot;
black = &quot;#000000&quot;
</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>The default palette uses the terminal's default 16 colors, and the colors names
are listed below. The <code>[palette]</code> section in the config file takes precedence
over it and is merged into the default palette.</p>
<table><thead><tr><th>Color Name</th></tr></thead><tbody>

<p>The following is a list of scopes available to use for styling.</p>
<h4 id="syntax-highlighting"><a class="header" href="#syntax-highlighting">Syntax highlighting</a></h4>
<p>These keys match <a href="https://tree-sitter.github.io/tree-sitter/syntax-highlighting#theme">tree-sitter scopes</a>.</p>
<p>For a given highlight produced, styling will be determined based on the longest matching theme key. For example, the highlight <code>function.builtin.static</code> would match the key <code>function.builtin</code> rather than <code>function</code>.</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 future).</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 = &quot;move_char_left&quot; # Maps the 'a' key to the move_char_left command
w = &quot;move_line_up&quot; # Maps the 'w' key move_line_up
&quot;C-S-esc&quot; = &quot;extend_line&quot; # Maps Control-Shift-Escape to extend_line
g = { a = &quot;code_action&quot; } # Maps `ga` to show possible code actions
[keys.insert]
&quot;A-x&quot; = &quot;normal_mode&quot; # Maps Alt-X to enter normal mode
j = { k = &quot;normal_mode&quot; } # Maps `jk` to exit insert 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>

<p>Textobjects that are language specific (<a href="guides/../usage.html#textobjects">like functions, classes, etc</a>)
require an accompanying tree-sitter grammar and a <code>textobjects.scm</code> query file
to work properly. Tree-sitter allows us to query the source code syntax tree
and capture specific parts of it. The queries are written in a lisp dialect.
More information on how to write queries can be found in the <a href="guides/tree-sitter-queries">official tree-sitter
documentation</a>.</p>
<p>Query files should be placed in <code>runtime/queries/{language}/textobjects.scm</code>
when contributing. Note that to test the query files locally you should put
them under your local runtime directory (<code>~/.config/helix/runtime</code> on Linux
for example).</p>
<p>The following <a href="https://tree-sitter.github.io/tree-sitter/using-parsers#capturing-nodes">captures</a> are recognized:</p>
