<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>"hc</code> - Store the selection in register <code>h</code> and then change it (delete and enter insert mode).</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 selections (yay!). For example, to change every occurrence 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="syntax-tree-motions"><a class="header" href="#syntax-tree-motions">Syntax-tree Motions</a></h2>
|
|
<p><code>A-p</code>, <code>A-o</code>, <code>A-i</code>, and <code>A-n</code> (or <code>Alt</code> and arrow keys) move the primary
|
|
selection according to the selection's place in the syntax tree. Let's walk
|
|
through an example to get familiar with them. Many languages have a syntax like
|
|
so for function calls:</p>
|
|
<pre><code>func(arg1, arg2, arg3)
|
|
</code></pre>
|
|
<p>A function call might be parsed by tree-sitter into a tree like the following.</p>
|
|
<pre><code class="language-tsq">(call
|
|
function: (identifier) ; func
|
|
arguments:
|
|
(arguments ; (arg1, arg2, arg3)
|
|
(identifier) ; arg1
|
|
(identifier) ; arg2
|
|
(identifier))) ; arg3
|
|
</code></pre>
|
|
<p>Use <code>:tree-sitter-subtree</code> to view the syntax tree of the primary selection. In
|
|
a more intuitive tree format:</p>
|
|
<pre><code> ┌────┐
|
|
│call│
|
|
┌─────┴────┴─────┐
|
|
│ │
|
|
┌─────▼────┐ ┌────▼────┐
|
|
│identifier│ │arguments│
|
|
│ "func" │ ┌────┴───┬─────┴───┐
|
|
└──────────┘ │ │ │
|
|
│ │ │
|
|
┌─────────▼┐ ┌────▼─────┐ ┌▼─────────┐
|
|
│identifier│ │identifier│ │identifier│
|
|
│ "arg1" │ │ "arg2" │ │ "arg3" │
|
|
└──────────┘ └──────────┘ └──────────┘
|
|
</code></pre>
|
|
<p>Say we have a selection that wraps <code>arg1</code>. The selection is on the <code>arg1</code> leaf
|
|
in the tree above.</p>
|
|
<pre><code>func([arg1], arg2, arg3)
|
|
</code></pre>
|
|
<p>Using <code>A-n</code> would select the next sibling in the syntax tree: <code>arg2</code>.</p>
|
|
<pre><code>func(arg1, [arg2], arg3)
|
|
</code></pre>
|
|
<p>While <code>A-o</code> would expand the selection to the parent node. In the tree above we
|
|
can see that we would select the <code>arguments</code> node.</p>
|
|
<pre><code>func[(arg1, arg2, arg3)]
|
|
</code></pre>
|
|
<p>There is also some nuanced behavior that prevents you from getting stuck on a
|
|
node with no sibling. If we have a selection on <code>arg1</code>, <code>A-p</code> would bring us
|
|
to the previous child node. Since <code>arg1</code> doesn't have a sibling to its left,
|
|
though, we climb the syntax tree and then take the previous selection. So <code>A-p</code>
|
|
will move the selection over to the "func" <code>identifier</code>.</p>
|
|
<pre><code>[func](arg1, arg2, arg3)
|
|
</code></pre>

<h2 id="select--extend-mode"><a class="header" href="#select--extend-mode">Select / extend mode</a></h2>
|
|
<p>This mode echoes Normal mode, but changes any movements to extend
|
|
selections rather than replace them. Goto motions are also changed to
|
|
extend, so that <code>vgl</code> for example extends the selection to the end of
|
|
the line.</p>
|
|
<p>Search is also affected. By default, <code>n</code> and <code>N</code> will remove the current
|
|
selection and select the next instance of the search term. Toggling this
|
|
mode before pressing <code>n</code> or <code>N</code> makes it possible to keep the current
|
|
selection. Toggling it on and off during your iterative searching allows
|
|
you to selectively add search terms to your selections.</p>

|
|
<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> and Helix's <a href="https://github.com/helix-editor/helix/wiki/Migrating-from-Vim">Migrating from Vim</a>.</p>

|
|
<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>Hint: You can easily open the config file by typing <code>:config-open</code> within Helix normal mode.</p>
|
|
</blockquote>
|

<p>Example config:</p>

<div style="break-before: page; page-break-before: always;"></div><h1 id="themes"><a class="header" href="#themes">Themes</a></h1>
|
|
<p>To use a theme add <code>theme = "<name>"</code> to your <a href="./configuration.html"><code>config.toml</code></a> at the very top of the file before the first section or select it during runtime using <code>:theme <name></code>.</p>
|
|
<h2 id="creating-a-theme"><a class="header" href="#creating-a-theme">Creating a theme</a></h2>
|
|
<p>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>). The directory might have to be created beforehand.</p>
|
|
<p>The names "default" and "base16_default" are reserved for the builtin themes and cannot be overridden by user defined themes.</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>
|
|
<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>

<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>

<p>One-way key remapping is temporarily supported via a simple TOML configuration

|
|
<p>To remap keys, write a <code>config.toml</code> file in your <code>helix</code> configuration
|

this:</p>

<p>Language-specific settings and settings for language servers are configured

in <code>languages.toml</code> files.</p>
|
|
<h2 id="languagestoml-files"><a class="header" href="#languagestoml-files"><code>languages.toml</code> files</a></h2>
|

<p>There are three possible <code>languages.toml</code> files. The first is compiled into

Helix and lives in the <a href="https://github.com/helix-editor/helix/blob/master/languages.toml">Helix repository</a>.
|
|
This provides the default configurations for languages and language servers.</p>
|
|
<p>You may define a <code>languages.toml</code> in your <a href="./configuration.html">configuration directory</a>

|
which overrides values from the built-in language configuration. For example
|
|
to disable auto-LSP-formatting in Rust:</p>

<pre><code class="language-toml"># in <config_dir>/helix/languages.toml
|
|
|
|
[[language]]
|

name = "rust"
|

</code></pre>
|
|
<p>Language configuration may also be overridden local to a project by creating
|
|
a <code>languages.toml</code> file under a <code>.helix</code> directory. Its settings will be merged
|

with the language configuration in the configuration directory and the built-in
|
|
configuration.</p>

<pre><code class="language-toml">[[language]]
|

|
|
<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="https://tree-sitter.github.io/tree-sitter/using-parsers#query-syntax">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><a href="guides/../usage.html#tree-sitter-textobject-based-navigation">Tree-sitter based navigation</a> is done using captures in the

<li><code>object.movement</code></li>
|
|
<li><code>object.around</code></li>
|
|
<li><code>object.inside</code></li>
|
|
</ul>
|
|
<p>For example if a <code>function.around</code> capture has been already defined for a language
|
|
in it's <code>textobjects.scm</code> file, function navigation should also work automatically.
|
|
<code>function.movement</code> should be defined only if the node captured by <code>function.around</code>

<div style="break-before: page; page-break-before: always;"></div><h1 id="adding-indent-queries"><a class="header" href="#adding-indent-queries">Adding Indent Queries</a></h1>
|
|
<p>Helix uses tree-sitter to correctly indent new lines. This requires
|
|
a tree-sitter grammar and an <code>indent.scm</code> query file placed in
|
|
<code>runtime/queries/{language}/indents.scm</code>. The indentation for a line
|
|
is calculated by traversing the syntax tree from the lowest node at the
|
|
beginning of the new line. Each of these nodes contributes to the total
|
|
indent when it is captured by the query (in what way depends on the name
|
|
of the capture).</p>
|
|
<p>Note that it matters where these added indents begin. For example,
|
|
multiple indent level increases that start on the same line only increase
|
|
the total indent level by 1.</p>
|
|
<h2 id="scopes-1"><a class="header" href="#scopes-1">Scopes</a></h2>
|
|
<p>Added indents don't always apply to the whole node. For example, in most
|
|
cases when a node should be indented, we actually only want everything
|
|
except for its first line to be indented. For this, there are several
|
|
scopes (more scopes may be added in the future if required):</p>
|
|
<ul>
|
|
<li>
|
|
<p><code>all</code>:
|
|
This scope applies to the whole captured node. This is only different from
|
|
<code>tail</code> when the captured node is the first node on its line.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>tail</code>:
|
|
This scope applies to everything except for the first line of the
|
|
captured node.</p>
|
|
</li>
|
|
</ul>
|
|
<p>Every capture type has a default scope which should do the right thing
|
|
in most situations. When a different scope is required, this can be
|
|
changed by using a <code>#set!</code> declaration anywhere in the pattern:</p>
|
|
<pre><code class="language-scm">(assignment_expression
|
|
right: (_) @indent
|
|
(#set! "scope" "all"))
|
|
</code></pre>
|
|
<h2 id="capture-types"><a class="header" href="#capture-types">Capture Types</a></h2>
|
|
<ul>
|
|
<li>
|
|
<p><code>@indent</code> (default scope <code>tail</code>):
|
|
Increase the indent level by 1. Multiple occurrences in the same line
|
|
don't stack. If there is at least one <code>@indent</code> and one <code>@outdent</code>
|
|
capture on the same line, the indent level isn't changed at all.</p>
|
|
</li>
|
|
<li>
|
|
<p><code>@outdent</code> (default scope <code>all</code>):
|
|
Decrease the indent level by 1. The same rules as for <code>@indent</code> apply.</p>
|
|
</li>
|
|
</ul>
|
|
<h2 id="predicates"><a class="header" href="#predicates">Predicates</a></h2>
|
|
<p>In some cases, an S-expression cannot express exactly what pattern should be matched.
|
|
For that, tree-sitter allows for predicates to appear anywhere within a pattern,
|
|
similar to how <code>#set!</code> declarations work:</p>
|
|
<pre><code class="language-scm">(some_kind
|
|
(child_kind) @indent
|
|
(#predicate? arg1 arg2 ...)
|
|
)
|
|
</code></pre>
|
|
<p>The number of arguments depends on the predicate that's used.
|
|
Each argument is either a capture (<code>@name</code>) or a string (<code>"some string"</code>).
|
|
The following predicates are supported by tree-sitter:</p>
|
|
<ul>
|
|
<li>
|
|
<p><code>#eq?</code>/<code>#not-eq?</code>:
|
|
The first argument (a capture) must/must not be equal to the second argument
|
|
(a capture or a string).</p>
|
|
</li>
|
|
<li>
|
|
<p><code>#match?</code>/<code>#not-match?</code>:
|
|
The first argument (a capture) must/must not match the regex given in the
|
|
second argument (a string).</p>
|
|
</li>
|
|
</ul>
|
|
<p>Additionally, we support some custom predicates for indent queries:</p>
|
|
<ul>
|
|
<li>
