Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

Copyright 2010, 2012 Adobe Systems Incorporated (http://www.adobe.com/), with Reserved Font Name 'Source'. All Rights Reserved. Source is a trademark of Adobe Systems Incorporated in the United States and/or other countries.
This Font Software is licensed under the SIL Open Font License, Version 1.1.
This license is copied below, and is also available with a FAQ at:

-----------------------------------------------------------
SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
-----------------------------------------------------------
PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.
The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.
DEFINITIONS
"Font Software" refers to the set of files released by the Copyright
Holder(s) under this license and clearly marked as such. This may
include source files, build scripts and documentation.
"Reserved Font Name" refers to any names specified as such after the
copyright statement(s).
"Original Version" refers to the collection of Font Software components as
distributed by the Copyright Holder(s).
"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to a
new environment.
"Author" refers to any designer, engineer, programmer, technical
writer or other person who contributed to the Font Software.
PERMISSION & CONDITIONS
Permission is hereby granted, free of charge, to any person obtaining
a copy of the Font Software, to use, study, copy, merge, embed, modify,
redistribute, and sell modified and unmodified copies of the Font
Software, subject to the following conditions:
1) Neither the Font Software nor any of its individual components,
in Original or Modified Versions, may be sold by itself.
2) Original or Modified Versions of the Font Software may be bundled,
redistributed and/or sold with any software, provided that each copy
contains the above copyright notice and this license. These can be
included either as stand-alone text files, human-readable headers or
in the appropriate machine-readable metadata fields within text or
binary files as long as those fields can be easily viewed by the user.
3) No Modified Version of the Font Software may use the Reserved Font
Name(s) unless explicit written permission is granted by the corresponding
Copyright Holder. This restriction only applies to the primary font name as
presented to the users.
4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
Software shall not be used to promote, endorse or advertise any
Modified Version, except to acknowledge the contribution(s) of the
Copyright Holder(s) and the Author(s) or with their explicit written
permission.
5) The Font Software, modified or unmodified, in part or in whole,
must be distributed entirely under this license, and must not be
distributed under any other license. The requirement for fonts to
remain under this license does not apply to any document created
using the Font Software.
TERMINATION
This license becomes null and void if any of the above conditions are
not met.
DISCLAIMER
THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT
OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE
COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM

<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="queries"><a class="header" href="#queries">Queries</a></h2>
<p>For a language to have syntax-highlighting and indentation among
other things, you have to add queries. Add a directory for your
language with the path <code>runtime/queries/&lt;name&gt;/</code>. The tree-sitter
<a href="https://tree-sitter.github.io/tree-sitter/syntax-highlighting#queries">website</a>
gives more info on how to write queries.</p>
<blockquote>
<p>NOTE: When evaluating queries, the first matching query takes
precedence, which is different from other editors like neovim where
the last matching query supersedes the ones before it. See
<a href="https://github.com/helix-editor/helix/pull/1170#issuecomment-997294090">this issue</a> for an example.</p>
</blockquote>
<h2 id="common-issues"><a class="header" href="#common-issues">Common Issues</a></h2>
<ul>
<li>
<p>If you get errors when running after switching branches, you may have to update the tree-sitter grammars. Run <code>hx --grammar fetch</code> to fetch the grammars and <code>hx --grammar build</code> to build any out-of-date grammars.</p>
</li>
<li>
<p>If a parser is segfaulting or you want to remove the parser, make sure to remove the compiled parser in <code>runtime/grammar/&lt;name&gt;.so</code></p>
</li>
<li>
<p>The indents query is <code>indents.toml</code>, <em>not</em> <code>indents.scm</code>. See <a href="https://github.com/helix-editor/helix/issues/114">this</a> issue for more information.</p>

<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"><a class="header" href="#scopes">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 occurences 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>
<p><code>#not-kind-eq?</code>:
The kind of the first argument (a capture) must not be equal to the second
argument (a string).</p>
</li>
<li>
<p><code>#same-line?</code>/<code>#not-same-line?</code>:
The captures given by the 2 arguments must/must not start on the same line.</p>
</li>
</ul>

<h1 id="adding-textobject-queries"><a class="header" href="#adding-textobject-queries">Adding Textobject Queries</a></h1>
<p>Textobjects that are language specific (<a href="../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>The following <a href="https://tree-sitter.github.io/tree-sitter/using-parsers#capturing-nodes">captures</a> are recognized:</p>
<div class="table-wrapper"><table><thead><tr><th>Capture Name</th></tr></thead><tbody>
<tr><td><code>function.inside</code></td></tr>
<tr><td><code>function.around</code></td></tr>
<tr><td><code>class.inside</code></td></tr>
<tr><td><code>class.around</code></td></tr>
<tr><td><code>parameter.inside</code></td></tr>
<tr><td><code>comment.inside</code></td></tr>
<tr><td><code>comment.around</code></td></tr>
</tbody></table>
</div>
<p><a href="https://github.com/search?q=repo%3Ahelix-editor%2Fhelix+filename%3Atextobjects.scm&amp;type=Code&amp;ref=advsearch&amp;l=&amp;l=">Example query files</a> can be found in the helix GitHub repository.</p>
<h2 id="queries-for-textobject-based-navigation"><a class="header" href="#queries-for-textobject-based-navigation">Queries for Textobject Based Navigation</a></h2>
<p><a href="../usage.html#tree-sitter-textobject-based-navigation">Tree-sitter based navigation</a> is done using captures in the
following order:</p>
<ul>
<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>
doesn't make sense in a navigation context.</p>

<p>We provide pre-built binaries on the <a href="https://github.com/helix-editor/helix/releases">GitHub Releases page</a>.</p>
<p><a href="https://repology.org/project/helix/versions"><img src="https://repology.org/badge/vertical-allrepos/helix.svg" alt="Packaging status" /></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 with <code>nix develop</code>.</p>
<p>Flake outputs are cached for each push to master using
<a href="https://www.cachix.org/">Cachix</a>. With Cachix
<a href="https://docs.cachix.org/installation">installed</a>, <code>cachix use helix</code> will
configure Nix to use cached outputs when possible.</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>A <a href="https://aur.archlinux.org/packages/helix-git/">helix-git</a> package is also available on the AUR, which builds the master branch.</p>
<h3 id="fedora-linux"><a class="header" href="#fedora-linux">Fedora Linux</a></h3>
<p>You can install the COPR package for Helix via</p>
<pre><code>sudo dnf copr enable varlad/helix
sudo dnf install helix
</code></pre>
<h3 id="void-linux"><a class="header" href="#void-linux">Void Linux</a></h3>
<pre><code>sudo xbps-install helix
</code></pre>
<h2 id="build-from-source"><a class="header" href="#build-from-source">Build from source</a></h2>
<pre><code>git clone 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 class="table-wrapper"><table><thead><tr><th>OS</th><th>command</th></tr></thead><tbody>

<h2 id="building-tree-sitter-grammars"><a class="header" href="#building-tree-sitter-grammars">Building tree-sitter grammars</a></h2>
<p>Tree-sitter grammars must be fetched and compiled if not pre-packaged.
Fetch grammars with <code>hx --grammar fetch</code> (requires <code>git</code>) and compile them
with <code>hx --grammar build</code> (requires a C compiler).</p>

<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>

<h1 id="languages"><a class="header" href="#languages">Languages</a></h1>
<p>Language-specific settings and settings for particular language servers can be configured in a <code>languages.toml</code> file placed in your <a href="./configuration.html">configuration directory</a>. Helix actually uses two <code>languages.toml</code> files, the <a href="https://github.com/helix-editor/helix/blob/master/languages.toml">first one</a> is in the main helix repository; it contains the default settings for each language and is included in the helix binary at compile time. Users who want to see the available settings and options can either reference the helix repo's <code>languages.toml</code> file, or consult the table in the <a href="./guides/adding_languages.html">adding languages</a> section.</p>
<p>A local <code>languages.toml</code> can be created within a <code>.helix</code> directory. Its settings will be merged with both the global and default configs.</p>
<p>Changes made to the <code>languages.toml</code> file in a user's <a href="./configuration.html">configuration directory</a> are merged with helix's defaults on start-up, such that a user's settings will take precedence over defaults in the event of a collision. For example, the default <code>languages.toml</code> sets rust's <code>auto-format</code> to <code>true</code>. If a user wants to disable auto-format, they can change the <code>languages.toml</code> in their <a href="./configuration.html">configuration directory</a> to make the rust entry read like the example below; the new key/value pair <code>auto-format = false</code> will override the default when the two sets of settings are merged on start-up:</p>
<pre><code class="language-toml"># in &lt;config_dir&gt;/helix/languages.toml
[[language]]
name = "rust"
auto-format = false
</code></pre>
<h2 id="tree-sitter-grammars"><a class="header" href="#tree-sitter-grammars">Tree-sitter grammars</a></h2>
<p>Tree-sitter grammars can also be configured in <code>languages.toml</code>:</p>
<pre><code class="language-toml"># in &lt;config_dir&gt;/helix/languages.toml
[[grammar]]
name = "rust"
source = { git = "https://github.com/tree-sitter/tree-sitter-rust", rev = "a250c4582510ff34767ec3b7dcdd3c24e8c8aa68" }
[[grammar]]
name = "c"
source = { path = "/path/to/tree-sitter-c" }
</code></pre>
<p>You may use a top-level <code>use-grammars</code> key to control which grammars are fetched and built.</p>
<pre><code class="language-toml"># Note: this key must come **before** the [[language]] and [[grammar]] sections
use-grammars = { only = [ "rust", "c", "cpp" ] }
# or
use-grammars = { except = [ "yaml", "json" ] }
</code></pre>
<p>When omitted, all grammars are fetched and built.</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]
C-s = ":w" # Maps the Control-s to the typable command :w which is an alias for :write (save file)
C-o = ":open ~/.config/helix/config.toml" # Maps the Control-o to opening of the helix config file
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
"ret" = ["open_below", "normal_mode"] # Maps the enter key to open_below then re-enter normal mode
[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>
<blockquote>
<p>NOTE: Typable commands can also be remapped, remember to keep the <code>:</code> prefix to indicate it's a typable command.</p>
</blockquote>
<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>
<div class="table-wrapper"><table><thead><tr><th>Key name</th><th>Representation</th></tr></thead><tbody>
<tr><td>Backspace</td><td><code>"backspace"</code></td></tr>
<tr><td>Space</td><td><code>"space"</code></td></tr>
<tr><td>Return/Enter</td><td><code>"ret"</code></td></tr>
<tr><td>&lt;</td><td><code>"lt"</code></td></tr>
<tr><td>&gt;</td><td><code>"gt"</code></td></tr>
<tr><td>+</td><td><code>"plus"</code></td></tr>
<tr><td>-</td><td><code>"minus"</code></td></tr>
<tr><td>;</td><td><code>"semicolon"</code></td></tr>
<tr><td>%</td><td><code>"percent"</code></td></tr>
<tr><td>Left</td><td><code>"left"</code></td></tr>
<tr><td>Right</td><td><code>"right"</code></td></tr>
<tr><td>Up</td><td><code>"up"</code></td></tr>
<tr><td>Down</td><td><code>"down"</code></td></tr>
<tr><td>Home</td><td><code>"home"</code></td></tr>
<tr><td>End</td><td><code>"end"</code></td></tr>
<tr><td>Page Up</td><td><code>"pageup"</code></td></tr>
<tr><td>Page Down</td><td><code>"pagedown"</code></td></tr>
<tr><td>Tab</td><td><code>"tab"</code></td></tr>
<tr><td>Delete</td><td><code>"del"</code></td></tr>
<tr><td>Insert</td><td><code>"ins"</code></td></tr>
<tr><td>Null</td><td><code>"null"</code></td></tr>
<tr><td>Escape</td><td><code>"esc"</code></td></tr>
</tbody></table>
</div>
<p>Keys can be disabled by binding them to the <code>no_op</code> command.</p>
<p>Commands can be found at <a href="https://docs.helix-editor.com/keymap.html">Keymap</a> Commands.</p>
<blockquote>
<p>Commands can also be found in the source code at <a href="https://github.com/helix-editor/helix/blob/master/helix-term/src/commands.rs"><code>helix-term/src/commands.rs</code></a> at the invocation of <code>static_commands!</code> macro and the <code>TypableCommandList</code>.</p>

<h1 id="themes"><a class="header" href="#themes">Themes</a></h1>
<p>To use a theme add <code>theme = "&lt;name&gt;"</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 &lt;name&gt;</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>
<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>
<div class="table-wrapper"><table><thead><tr><th>Color Name</th></tr></thead><tbody>
<tr><td><code>black</code></td></tr>
<tr><td><code>red</code></td></tr>
<tr><td><code>green</code></td></tr>
<tr><td><code>yellow</code></td></tr>
<tr><td><code>blue</code></td></tr>

</tbody></table>
</div>
<h3 id="modifiers"><a class="header" href="#modifiers">Modifiers</a></h3>
<p>The following values may be used as modifiers.</p>
<p>Less common modifiers might not be supported by your terminal emulator.</p>
<div class="table-wrapper"><table><thead><tr><th>Modifier</th></tr></thead><tbody>
<tr><td><code>bold</code></td></tr>
<tr><td><code>dim</code></td></tr>

<h3 id="scopes"><a class="header" href="#scopes">Scopes</a></h3>
<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>We use a similar set of scopes as
<a href="https://www.sublimetext.com/docs/scope_naming.html">SublimeText</a>. See also

<!-- sidebar iframe generated using mdBook
This is a frame, and not included directly in the page, to control the total size of the
book. The TOC contains an entry for each page, so if each page includes a copy of the TOC,
the total size of the page becomes O(n**2).
The frame is only used as a fallback when JS is turned off. When it's on, the sidebar is
instead added to the main page by `toc.js` instead. The JavaScript mode is better
because, when running in a `file:///` URL, the iframed page would not be Same-Origin as
the rest of the page, so the sidebar and the main page theme would fall out of sync.

<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>"</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>
</ul>
<h3 id="special-registers"><a class="header" href="#special-registers">Special Registers</a></h3>
<div class="table-wrapper"><table><thead><tr><th>Register character</th><th>Contains</th></tr></thead><tbody>
<tr><td><code>/</code></td><td>Last search</td></tr>
<tr><td><code>:</code></td><td>Last executed command</td></tr>
<tr><td><code>"</code></td><td>Last yanked text</td></tr>
<tr><td><code>_</code></td><td>Black hole</td></tr>
</tbody></table>
</div>
<blockquote>
<p>There is no special register for copying to system clipboard, instead special commands and keybindings are provided. See the <a href="keymap.html#space-mode">keymap</a> for the specifics.
The black hole register works as a no-op register, meaning no data will be written to / read from it.</p>
</blockquote>
<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 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="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>
<p><img src="https://user-images.githubusercontent.com/23398472/124231131-81a4bb00-db2d-11eb-9d10-8e577ca7b177.gif" alt="textobject-demo" />
<img src="https://user-images.githubusercontent.com/23398472/132537398-2a2e0a54-582b-44ab-a77f-eb818942203d.gif" alt="textobject-treesitter-demo" /></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>
</ul>
<div class="table-wrapper"><table><thead><tr><th>Key after <code>mi</code> or <code>ma</code></th><th>Textobject selected</th></tr></thead><tbody>
<tr><td><code>w</code></td><td>Word</td></tr>
<tr><td><code>W</code></td><td>WORD</td></tr>
<tr><td><code>(</code>, <code>[</code>, <code>'</code>, etc</td><td>Specified surround pairs</td></tr>
<tr><td><code>f</code></td><td>Function</td></tr>
<tr><td><code>c</code></td><td>Class</td></tr>
<tr><td><code>a</code></td><td>Argument/parameter</td></tr>
<tr><td><code>o</code></td><td>Comment</td></tr>
</tbody></table>
</div>
<blockquote>
<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="./lang-support.html">Only
some grammars</a> currently have the query file implemented.
Contributions are welcome!</p>
</blockquote>
<h2 id="tree-sitter-textobject-based-navigation"><a class="header" href="#tree-sitter-textobject-based-navigation">Tree-sitter Textobject Based Navigation</a></h2>
<p>Navigating between functions, classes, parameters, etc is made
possible by leveraging tree-sitter and textobjects queries. For
example to move to the next function use <code>]f</code>, to move to previous
class use <code>[c</code>, and so on.</p>
<p><img src="https://user-images.githubusercontent.com/23398472/152332550-7dfff043-36a2-4aec-b8f2-77c13eb56d6f.gif" alt="tree-sitter-nav-demo" /></p>
<p>See the <a href="./keymap.html#unimpaired">unimpaired</a> section of the keybind
documentation for the full reference.</p>
<blockquote>
<p>NOTE: This feature is dependent on tree-sitter based textobjects
and therefore requires the corresponding query file to work properly.</p>

</ul>
<p>Requirements:</p>
<p>Clone the Helix GitHub repository into a directory of your choice. The
examples in this documentation assume installation into either <code>~/src/</code> on
Linux and macOS, or <code>%userprofile%\src\</code> on Windows.</p>
<ul>
<li>The <a href="https://www.rust-lang.org/tools/install">Rust toolchain</a></li>
<li>The <a href="https://git-scm.com/">Git version control system</a></li>
<li>A C++14 compatible compiler to build the tree-sitter grammars, for example GCC or Clang</li>
</ul>
<p>If you are using the <code>musl-libc</code> standard library instead of <code>glibc</code> the following environment variable must be set during the build to ensure tree-sitter grammars can be loaded correctly:</p>
<pre><code class="language-sh">RUSTFLAGS="-C target-feature=-crt-static"
</code></pre>
<ol>
<li>
<p>Clone the repository:</p>
<pre><code class="language-sh">git clone https://github.com/helix-editor/helix
cd helix
</code></pre>
</li>
<li>
<p>Compile from source:</p>
<pre><code class="language-sh">cargo install --path helix-term --locked
</code></pre>
<p>This command will create the <code>hx</code> executable and construct the tree-sitter
grammars in the local <code>runtime</code> folder.</p>
</li>
</ol>
<blockquote>
<p>💡 If you do not want to fetch or build grammars, set an environment variable <code>HELIX_DISABLE_AUTO_GRAMMAR_BUILD</code></p>
</blockquote>
<blockquote>
<p>💡 Tree-sitter grammars can be fetched and compiled if not pre-packaged. Fetch
grammars with <code>hx --grammar fetch</code> and compile them with
<code>hx --grammar build</code>. This will install them in
the <code>runtime</code> directory within the user's helix config directory (more
<a href="#multiple-runtime-directories">details below</a>).</p>
</blockquote>
<h3 id="configuring-helixs-runtime-files"><a class="header" href="#configuring-helixs-runtime-files">Configuring Helix's runtime files</a></h3>
<h4 id="linux-and-macos"><a class="header" href="#linux-and-macos">Linux and macOS</a></h4>
<p>The <strong>runtime</strong> directory is one below the Helix source, so either export a
<code>HELIX_RUNTIME</code> environment variable to point to that directory and add it to
your <code>~/.bashrc</code> or equivalent:</p>
<pre><code class="language-sh">export HELIX_RUNTIME=~/src/helix/runtime
</code></pre>
<p>Or, create a symbolic link:</p>
<pre><code class="language-sh">ln -Ts $PWD/runtime ~/.config/helix/runtime
</code></pre>
<p>If the above command fails to create a symbolic link because the file exists either move <code>~/.config/helix/runtime</code> to a new location or delete it, then run the symlink command above again.</p>
<h4 id="windows"><a class="header" href="#windows">Windows</a></h4>
<p>Either set the <code>HELIX_RUNTIME</code> environment variable to point to the runtime files using the Windows setting (search for
<code>Edit environment variables for your account</code>) or use the <code>setx</code> command in
Cmd:</p>
<pre><code class="language-sh">setx HELIX_RUNTIME "%userprofile%\source\repos\helix\runtime"
</code></pre>
<blockquote>
<p>💡 <code>%userprofile%</code> resolves to your user directory like
<code>C:\Users\Your-Name\</code> for example.</p>
</blockquote>
<p>Or, create a symlink in <code>%appdata%\helix\</code> that links to the source code directory:</p>
<div class="table-wrapper"><table><thead><tr><th>Method</th><th>Command</th></tr></thead><tbody>
<tr><td>PowerShell</td><td><code>New-Item -ItemType Junction -Target "runtime" -Path "$Env:AppData\helix\runtime"</code></td></tr>
<tr><td>Cmd</td><td><code>cd %appdata%\helix</code> <br/> <code>mklink /D runtime "%userprofile%\src\helix\runtime"</code></td></tr>
</tbody></table>
</div>
<blockquote>
<p>💡 On Windows, creating a symbolic link may require running PowerShell or
Cmd as an administrator.</p>
</blockquote>
<h4 id="multiple-runtime-directories"><a class="header" href="#multiple-runtime-directories">Multiple runtime directories</a></h4>
<p>When Helix finds multiple runtime directories it will search through them for files in the
following order:</p>
<ol>
<li><code>runtime/</code> sibling directory to <code>$CARGO_MANIFEST_DIR</code> directory (this is intended for
developing and testing helix only).</li>
<li><code>runtime/</code> subdirectory of OS-dependent helix user config directory.</li>
<li><code>$HELIX_RUNTIME</code></li>
<li>Distribution-specific fallback directory (set at compile time—not run time—
with the <code>HELIX_DEFAULT_RUNTIME</code> environment variable)</li>
<li><code>runtime/</code> subdirectory of path to Helix executable.</li>
</ol>
<p>This order also sets the priority for selecting which file will be used if multiple runtime
directories have files with the same name.</p>
<h4 id="note-to-packagers"><a class="header" href="#note-to-packagers">Note to packagers</a></h4>
<p>If you are making a package of Helix for end users, to provide a good out of
the box experience, you should set the <code>HELIX_DEFAULT_RUNTIME</code> environment
variable at build time (before invoking <code>cargo build</code>) to a directory which
will store the final runtime files after installation. For example, say you want
to package the runtime into <code>/usr/lib/helix/runtime</code>. The rough steps a build
script could follow are:</p>
<ol>
<li><code>export HELIX_DEFAULT_RUNTIME=/usr/lib/helix/runtime</code></li>
<li><code>cargo build --profile opt --locked</code></li>
<li><code>cp -r runtime $BUILD_DIR/usr/lib/helix/</code></li>
<li><code>cp target/opt/hx $BUILD_DIR/usr/bin/hx</code></li>
</ol>
<p>This way the resulting <code>hx</code> binary will always look for its runtime directory in
<code>/usr/lib/helix/runtime</code> if the user has no custom runtime in <code>~/.config/helix</code>
or <code>HELIX_RUNTIME</code>.</p>
<h3 id="validating-the-installation"><a class="header" href="#validating-the-installation">Validating the installation</a></h3>
<p>To make sure everything is set up as expected you should run the Helix health
check:</p>
<pre><code class="language-sh">hx --health
</code></pre>
<p>For more information on the health check results refer to
<a href="https://github.com/helix-editor/helix/wiki/Healthcheck">Health check</a>.</p>
<h3 id="configure-the-desktop-shortcut"><a class="header" href="#configure-the-desktop-shortcut">Configure the desktop shortcut</a></h3>
<p>If your desktop environment supports the
<a href="https://specifications.freedesktop.org/menu-spec/menu-spec-latest.html">XDG desktop menu</a>
you can configure Helix to show up in the application menu by copying the
provided <code>.desktop</code> and icon files to their correct folders:</p>
<pre><code class="language-sh">cp contrib/Helix.desktop ~/.local/share/applications
cp contrib/helix.png ~/.icons # or ~/.local/share/icons
</code></pre>
<p>It is recommended to convert the links in the <code>.desktop</code> file to absolute paths to avoid potential problems:</p>
<pre><code class="language-sh">sed -i -e "s|Exec=hx %F|Exec=$(readlink -f ~/.cargo/bin/hx) %F|g" \
-e "s|Icon=helix|Icon=$(readlink -f ~/.icons/helix.png)|g" ~/.local/share/applications/Helix.desktop
</code></pre>
<p>To use another terminal than the system default, you can modify the <code>.desktop</code>
file. For example, to use <code>kitty</code>:</p>
<pre><code class="language-sh">sed -i "s|Exec=hx %F|Exec=kitty hx %F|g" ~/.local/share/applications/Helix.desktop
sed -i "s|Terminal=true|Terminal=false|g" ~/.local/share/applications/Helix.desktop
</code></pre>

<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>💡 You can easily open the config file by typing <code>:config-open</code> within Helix normal mode.</p>
</blockquote>
<p>Example config:</p>
<pre><code class="language-toml">theme = "onedark"
[editor]
line-number = "relative"
mouse = false
[editor.cursor-shape]
insert = "bar"
normal = "block"
select = "underline"
[editor.file-picker]
hidden = false
</code></pre>
<p>You can use a custom configuration file by specifying it with the <code>-c</code> or
<code>--config</code> command line argument, for example <code>hx -c path/to/custom-config.toml</code>.
You can reload the config file by issuing the <code>:config-reload</code> command. Alternatively, on Unix operating systems, you can reload it by sending the USR1
signal to the Helix process, such as by using the command <code>pkill -USR1 hx</code>.</p>
<p>Finally, you can have a <code>config.toml</code> local to a project by putting it under a <code>.helix</code> directory in your repository.
Its settings will be merged with the configuration directory <code>config.toml</code> and the built-in configuration.</p>

<p>Alternatively, Helix can be configured to use arbitary commands for clipboard integration:</p>
<pre><code class="language-toml">[editor.clipboard-provider.custom]
yank = { command = "cat", args = ["test.txt"] }
paste = { command = "tee", args = ["test.txt"] }
primary-yank = { command = "cat", args = ["test-primary.txt"] } # optional

Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must

pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade

except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

Copyright 2010, 2012 Adobe Systems Incorporated (http://www.adobe.com/), with Reserved Font Name 'Source'. All Rights Reserved. Source is a trademark of Adobe Systems Incorporated in the United States and/or other countries.
This Font Software is licensed under the SIL Open Font License, Version 1.1.
This license is copied below, and is also available with a FAQ at:
http://scripts.sil.org/OFL
-----------------------------------------------------------
SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
-----------------------------------------------------------
PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.
The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.
DEFINITIONS
"Font Software" refers to the set of files released by the Copyright
Holder(s) under this license and clearly marked as such. This may
include source files, build scripts and documentation.
"Reserved Font Name" refers to any names specified as such after the
copyright statement(s).
"Original Version" refers to the collection of Font Software components as
distributed by the Copyright Holder(s).
"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to a
new environment.
"Author" refers to any designer, engineer, programmer, technical
writer or other person who contributed to the Font Software.
PERMISSION & CONDITIONS
Permission is hereby granted, free of charge, to any person obtaining
a copy of the Font Software, to use, study, copy, merge, embed, modify,
redistribute, and sell modified and unmodified copies of the Font
Software, subject to the following conditions:
1) Neither the Font Software nor any of its individual components,
in Original or Modified Versions, may be sold by itself.
2) Original or Modified Versions of the Font Software may be bundled,
redistributed and/or sold with any software, provided that each copy
contains the above copyright notice and this license. These can be
included either as stand-alone text files, human-readable headers or
in the appropriate machine-readable metadata fields within text or
binary files as long as those fields can be easily viewed by the user.
3) No Modified Version of the Font Software may use the Reserved Font
Name(s) unless explicit written permission is granted by the corresponding
Copyright Holder. This restriction only applies to the primary font name as
presented to the users.
4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
Software shall not be used to promote, endorse or advertise any
Modified Version, except to acknowledge the contribution(s) of the
Copyright Holder(s) and the Author(s) or with their explicit written
permission.
5) The Font Software, modified or unmodified, in part or in whole,
must be distributed entirely under this license, and must not be
distributed under any other license. The requirement for fonts to
remain under this license does not apply to any document created
using the Font Software.
TERMINATION
This license becomes null and void if any of the above conditions are
not met.
DISCLAIMER
THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT
OF COPYRIGHT, PATENT, TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE
COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
INCLUDING ANY GENERAL, SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
DAMAGES, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
FROM, OUT OF THE USE OR INABILITY TO USE THE FONT SOFTWARE OR FROM
OTHER DEALINGS IN THE FONT SOFTWARE.

<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 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>
