<p>Vim-like registers can be used to yank and store text to be pasted later. Usage is similar, with <code>"</code> being used to select a register:</p>

<ul>

<li><code>"ay</code> - Yank the current selection to register <code>a</code>.</li>

<li><code>"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>"hc</code> - Store the selection in register <code>h</code> and then change it (delete and enter insert mode).</li>

<li><code>"md</code> - Store the selection in register <code>m</code> and delete it.</li>

<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="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>To display all language server messages in the status line add the following to your <code>config.toml</code>:</p>

|
|
<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"
|
|
</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 = "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>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>

<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>I'm still pondering whether to keep this mode or not. It changes movement

commands (including goto) to extend the existing selection instead of replacing it.</p>

<blockquote>
|
|
<p>NOTE: It's a bit confusing at the moment because extend hasn't been

implemented for all movement commands yet.</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 = "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
|
|
g = { a = "code_action" } # Maps `ga` to show possible code actions
|
|
|
|
[keys.insert]
|
|
"A-x" = "normal_mode" # Maps Alt-X to enter normal mode
|
|
j = { k = "normal_mode" } # 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>
