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

### `[editor.statusline]` Section
Allows configuring the statusline at the bottom of the editor.
The configuration distinguishes between three areas of the status line:
`[ ... ... LEFT ... ... | ... ... ... CENTER ... ... ... | ... ... RIGHT ... ... ]`
Statusline elements can be defined as follows:
```toml

### `[editor.lsp]` Section
| Key | Description | Default |
| --- | ----------- | ------- |
| `enable` | Enables LSP integration. Setting to false will completely disable language servers regardless of language settings.| `true` |
| `display-messages` | Display LSP progress messages below statusline[^1] | `false` |
| `auto-signature-help` | Enable automatic popup of signature help (parameter hints) | `true` |

| `goto-reference-include-declaration` | Include declaration in the goto references popup. | `true` |
[^1]: By default, a progress spinner is shown in the statusline beside the file path.
[^2]: You may also have to activate them in the LSP config for them to appear, not just in Helix. Inlay hints in Helix are still being improved on and may be a little bit laggy/janky under some circumstances. Please report any bugs you see so we can fix them!
### `[editor.cursor-shape]` Section
Defines the shape of cursor in each mode.
Valid values for these options are `block`, `bar`, `underline`, or `hidden`.
> 💡 Due to limitations of the terminal environment, only the primary cursor can
> change shape.
| Key | Description | Default |
| --- | ----------- | ------- |
| `normal` | Cursor shape in [normal mode][normal mode] | `block` |
| `insert` | Cursor shape in [insert mode][insert mode] | `block` |
| `select` | Cursor shape in [select mode][select mode] | `block` |
[normal mode]: ./keymap.md#normal-mode
[insert mode]: ./keymap.md#insert-mode
[select mode]: ./keymap.md#select--extend-mode
### `[editor.file-picker]` Section
Set options for file picker and global search. Ignoring a file means it is
not visible in the Helix file picker and global search.
All git related options are only enabled in a git repository.
| Key | Description | Default |
|--|--|---------|
|`hidden` | Enables ignoring hidden files | `true`
|`follow-symlinks` | Follow symlinks instead of ignoring them | `true`
|`deduplicate-links` | Ignore symlinks that point at files already shown in the picker | `true`
|`parents` | Enables reading ignore files from parent directories | `true`
|`ignore` | Enables reading `.ignore` files | `true`
|`git-ignore` | Enables reading `.gitignore` files | `true`
|`git-global` | Enables reading global `.gitignore`, whose path is specified in git's config: `core.excludesfile` option | `true`
|`git-exclude` | Enables reading `.git/info/exclude` files | `true`
|`max-depth` | Set with an integer value for maximum depth to recurse | Unset by default
Ignore files can be placed locally as `.ignore` or put in your home directory as `~/.ignore`. They support the usual ignore and negative ignore (unignore) rules used in `.gitignore` files.
Additionally, you can use Helix-specific ignore files by creating a local `.helix/ignore` file in the current workspace or a global `ignore` file located in your Helix config directory:
- Linux and Mac: `~/.config/helix/ignore`
- Windows: `%AppData%\helix\ignore`
Example:
```ini
# unignore in file picker and global search
!.github/
!.gitignore
!.gitattributes
```
### `[editor.auto-pairs]` Section
Enables automatic insertion of pairs to parentheses, brackets, etc. Can be a
simple boolean value, or a specific mapping of pairs of single characters.
To disable auto-pairs altogether, set `auto-pairs` to `false`:
```toml
[editor]
auto-pairs = false # defaults to `true`
```
The default pairs are <code>(){}[]''""``</code>, but these can be customized by
setting `auto-pairs` to a TOML table:
```toml
[editor.auto-pairs]
'(' = ')'
'{' = '}'
'[' = ']'
'"' = '"'
'`' = '`'
'<' = '>'
```
Additionally, this setting can be used in a language config. Unless
the editor setting is `false`, this will override the editor config in
documents with this language.
Example `languages.toml` that adds `<>` and removes `''`
```toml
[[language]]
name = "rust"
[language.auto-pairs]
'(' = ')'
'{' = '}'
'[' = ']'
'"' = '"'
'`' = '`'
'<' = '>'
```
### `[editor.search]` Section
Search specific options.
| Key | Description | Default |
|--|--|---------|
| `smart-case` | Enable smart case regex searching (case-insensitive unless pattern contains upper case characters) | `true` |
| `wrap-around`| Whether the search should wrap after depleting the matches | `true` |
### `[editor.whitespace]` Section
Options for rendering whitespace with visible characters. Use `:set whitespace.render all` to temporarily enable visible whitespace.
| Key | Description | Default |
|-----|-------------|---------|
| `render` | Whether to render whitespace. May either be `all` or `none`, or a table with sub-keys `space`, `nbsp`, `nnbsp`, `tab`, and `newline` | `none` |
| `characters` | Literal characters to use when rendering whitespace. Sub-keys may be any of `tab`, `space`, `nbsp`, `nnbsp`, `newline` or `tabpad` | See example below |
Example
```toml
[editor.whitespace]
render = "all"
# or control each character
[editor.whitespace.render]
space = "all"
tab = "all"
nbsp = "none"
nnbsp = "none"
newline = "none"
[editor.whitespace.characters]
space = "·"
nbsp = "⍽"
nnbsp = "␣"
tab = "→"
newline = "⏎"
tabpad = "·" # Tabs will look like "→···" (depending on tab width)
```
### `[editor.indent-guides]` Section
Options for rendering vertical indent guides.
| Key | Description | Default |
| --- | --- | --- |
| `render` | Whether to render indent guides | `false` |
| `character` | Literal character to use for rendering the indent guide | `│` |
| `skip-levels` | Number of indent levels to skip | `0` |
Example:
```toml
[editor.indent-guides]
render = true
character = "╎" # Some characters that work well: "▏", "┆", "┊", "⸽"
skip-levels = 1
```
### `[editor.gutters]` Section
For simplicity, `editor.gutters` accepts an array of gutter types, which will
use default settings for all gutter components.
```toml
[editor]
gutters = ["diff", "diagnostics", "line-numbers", "spacer"]
```
To customize the behavior of gutters, the `[editor.gutters]` section must
be used. This section contains top level settings, as well as settings for
specific gutter components as subsections.
| Key | Description | Default |
| --- | --- | --- |
| `layout` | A vector of gutters to display | `["diagnostics", "spacer", "line-numbers", "spacer", "diff"]` |
Example:
```toml
[editor.gutters]
layout = ["diff", "diagnostics", "line-numbers", "spacer"]
```
#### `[editor.gutters.line-numbers]` Section
Options for the line number gutter
| Key | Description | Default |
| --- | --- | --- |
| `min-width` | The minimum number of characters to use | `3` |
Example:
```toml
[editor.gutters.line-numbers]
min-width = 1
```
#### `[editor.gutters.diagnostics]` Section
Currently unused
#### `[editor.gutters.diff]` Section
The `diff` gutter option displays colored bars indicating whether a `git` diff represents that a line was added, removed or changed.
These colors are controlled by the theme attributes `diff.plus`, `diff.minus` and `diff.delta`.
Other diff providers will eventually be supported by a future plugin system.
There are currently no options for this section.
#### `[editor.gutters.spacer]` Section
Currently unused
### `[editor.soft-wrap]` Section
Options for soft wrapping lines that exceed the view width:
| Key | Description | Default |
| --- | --- | --- |
| `enable` | Whether soft wrapping is enabled. | `false` |
| `max-wrap` | Maximum free space left at the end of the line. | `20` |
| `max-indent-retain` | Maximum indentation to carry over when soft wrapping a line. | `40` |
| `wrap-indicator` | Text inserted before soft wrapped lines, highlighted with `ui.virtual.wrap` | `↪ ` |
| `wrap-at-text-width` | Soft wrap at `text-width` instead of using the full viewport size. | `false` |
Example:
```toml
[editor.soft-wrap]
enable = true
max-wrap = 25 # increase value to reduce forced mid-word wrapping
max-indent-retain = 0
wrap-indicator = "" # set wrap-indicator to "" to hide it
```
### `[editor.smart-tab]` Section
Options for navigating and editing using tab key.
| Key | Description | Default |
|------------|-------------|---------|
| `enable` | If set to true, then when the cursor is in a position with non-whitespace to its left, instead of inserting a tab, it will run `move_parent_node_end`. If there is only whitespace to the left, then it inserts a tab as normal. With the default bindings, to explicitly insert a tab character, press Shift-tab. | `true` |
| `supersede-menu` | Normally, when a menu is on screen, such as when auto complete is triggered, the tab key is bound to cycling through the items. This means when menus are on screen, one cannot use the tab key to trigger the `smart-tab` command. If this option is set to true, the `smart-tab` command always takes precedence, which means one cannot use the tab key to cycle through menu items. One of the other bindings must be used instead, such as arrow keys or `C-n`/`C-p`. | `false` |
Due to lack of support for S-tab in some terminals, the default keybindings don't fully embrace smart-tab editing experience. If you enjoy smart-tab navigation and a terminal that supports the [Enhanced Keyboard protocol](https://github.com/helix-editor/helix/wiki/Terminal-Support#enhanced-keyboard-protocol), consider setting extra keybindings:
```
[keys.normal]
tab = "move_parent_node_end"
S-tab = "move_parent_node_start"
[keys.insert]
S-tab = "move_parent_node_start"
[keys.select]
tab = "extend_parent_node_end"
S-tab = "extend_parent_node_start"
```

### `[editor.statusline]` Section
Allows configuring the statusline at the bottom of the editor.
The configuration distinguishes between three areas of the status line:
`[ ... ... LEFT ... ... | ... ... ... CENTER ... ... ... | ... ... RIGHT ... ... ]`
Statusline elements can be defined as follows:
```toml

### `[editor.lsp]` Section
| Key | Description | Default |
| --- | ----------- | ------- |
| `enable` | Enables LSP integration. Setting to false will completely disable language servers regardless of language settings.| `true` |
| `display-messages` | Display LSP progress messages below statusline[^1] | `false` |
| `auto-signature-help` | Enable automatic popup of signature help (parameter hints) | `true` |
| `display-inlay-hints` | Display inlay hints[^2] | `false` |
| `display-signature-help-docs` | Display docs under signature help popup | `true` |

| `goto-reference-include-declaration` | Include declaration in the goto references popup. | `true` |
[^1]: By default, a progress spinner is shown in the statusline beside the file path.
[^2]: You may also have to activate them in the LSP config for them to appear, not just in Helix. Inlay hints in Helix are still being improved on and may be a little bit laggy/janky under some circumstances. Please report any bugs you see so we can fix them!
### `[editor.cursor-shape]` Section
Defines the shape of cursor in each mode.
Valid values for these options are `block`, `bar`, `underline`, or `hidden`.
> 💡 Due to limitations of the terminal environment, only the primary cursor can
> change shape.
| Key | Description | Default |
| --- | ----------- | ------- |
| `normal` | Cursor shape in [normal mode][normal mode] | `block` |
| `insert` | Cursor shape in [insert mode][insert mode] | `block` |
| `select` | Cursor shape in [select mode][select mode] | `block` |
[normal mode]: ./keymap.md#normal-mode
[insert mode]: ./keymap.md#insert-mode
[select mode]: ./keymap.md#select--extend-mode
### `[editor.file-picker]` Section
Set options for file picker and global search. Ignoring a file means it is
not visible in the Helix file picker and global search.
All git related options are only enabled in a git repository.
| Key | Description | Default |
|--|--|---------|
|`hidden` | Enables ignoring hidden files | `true`
|`follow-symlinks` | Follow symlinks instead of ignoring them | `true`
|`deduplicate-links` | Ignore symlinks that point at files already shown in the picker | `true`
|`parents` | Enables reading ignore files from parent directories | `true`
|`ignore` | Enables reading `.ignore` files | `true`
|`git-ignore` | Enables reading `.gitignore` files | `true`
|`git-global` | Enables reading global `.gitignore`, whose path is specified in git's config: `core.excludesfile` option | `true`
|`git-exclude` | Enables reading `.git/info/exclude` files | `true`
|`max-depth` | Set with an integer value for maximum depth to recurse | Unset by default
Ignore files can be placed locally as `.ignore` or put in your home directory as `~/.ignore`. They support the usual ignore and negative ignore (unignore) rules used in `.gitignore` files.
Additionally, you can use Helix-specific ignore files by creating a local `.helix/ignore` file in the current workspace or a global `ignore` file located in your Helix config directory:
- Linux and Mac: `~/.config/helix/ignore`
- Windows: `%AppData%\helix\ignore`
Example:
```ini
# unignore in file picker and global search
!.github/
!.gitignore
!.gitattributes
```
### `[editor.auto-pairs]` Section
Enables automatic insertion of pairs to parentheses, brackets, etc. Can be a
simple boolean value, or a specific mapping of pairs of single characters.
To disable auto-pairs altogether, set `auto-pairs` to `false`:
```toml
[editor]
auto-pairs = false # defaults to `true`
```
The default pairs are <code>(){}[]''""``</code>, but these can be customized by
setting `auto-pairs` to a TOML table:
```toml
[editor.auto-pairs]
'(' = ')'
'{' = '}'
'[' = ']'
'"' = '"'
'`' = '`'
'<' = '>'
```
Additionally, this setting can be used in a language config. Unless
the editor setting is `false`, this will override the editor config in
documents with this language.
Example `languages.toml` that adds `<>` and removes `''`
```toml
[[language]]
name = "rust"
[language.auto-pairs]
'(' = ')'
'{' = '}'
'[' = ']'
'"' = '"'
'`' = '`'
'<' = '>'
```
### `[editor.auto-save]` Section
Control auto save behavior.
| Key | Description | Default |
|--|--|---------|

| `after-delay.enable` | Enable automatic saving after `auto-save.after-delay.timeout` milliseconds have passed since last edit. | `false` |
| `after-delay.timeout` | Time in milliseconds since last edit before auto save timer triggers. | `3000` |
### `[editor.search]` Section
Search specific options.
| Key | Description | Default |
|--|--|---------|
| `smart-case` | Enable smart case regex searching (case-insensitive unless pattern contains upper case characters) | `true` |
| `wrap-around`| Whether the search should wrap after depleting the matches | `true` |
### `[editor.whitespace]` Section
Options for rendering whitespace with visible characters. Use `:set whitespace.render all` to temporarily enable visible whitespace.
| Key | Description | Default |
|-----|-------------|---------|
| `render` | Whether to render whitespace. May either be `all` or `none`, or a table with sub-keys `space`, `nbsp`, `nnbsp`, `tab`, and `newline` | `none` |
| `characters` | Literal characters to use when rendering whitespace. Sub-keys may be any of `tab`, `space`, `nbsp`, `nnbsp`, `newline` or `tabpad` | See example below |
Example
```toml
[editor.whitespace]
render = "all"
# or control each character
[editor.whitespace.render]
space = "all"
tab = "all"
nbsp = "none"
nnbsp = "none"
newline = "none"
[editor.whitespace.characters]
space = "·"
nbsp = "⍽"
nnbsp = "␣"
tab = "→"
newline = "⏎"
tabpad = "·" # Tabs will look like "→···" (depending on tab width)
```
### `[editor.indent-guides]` Section
Options for rendering vertical indent guides.
| Key | Description | Default |
| --- | --- | --- |
| `render` | Whether to render indent guides | `false` |
| `character` | Literal character to use for rendering the indent guide | `│` |
| `skip-levels` | Number of indent levels to skip | `0` |
Example:
```toml
[editor.indent-guides]
render = true
character = "╎" # Some characters that work well: "▏", "┆", "┊", "⸽"
skip-levels = 1
```
### `[editor.gutters]` Section
For simplicity, `editor.gutters` accepts an array of gutter types, which will
use default settings for all gutter components.
```toml
[editor]
gutters = ["diff", "diagnostics", "line-numbers", "spacer"]
```
To customize the behavior of gutters, the `[editor.gutters]` section must
be used. This section contains top level settings, as well as settings for
specific gutter components as subsections.
| Key | Description | Default |
| --- | --- | --- |
| `layout` | A vector of gutters to display | `["diagnostics", "spacer", "line-numbers", "spacer", "diff"]` |
Example:
```toml
[editor.gutters]
layout = ["diff", "diagnostics", "line-numbers", "spacer"]
```
#### `[editor.gutters.line-numbers]` Section
Options for the line number gutter
| Key | Description | Default |
| --- | --- | --- |
| `min-width` | The minimum number of characters to use | `3` |
Example:
```toml
[editor.gutters.line-numbers]
min-width = 1
```
#### `[editor.gutters.diagnostics]` Section
Currently unused
#### `[editor.gutters.diff]` Section
The `diff` gutter option displays colored bars indicating whether a `git` diff represents that a line was added, removed or changed.
These colors are controlled by the theme attributes `diff.plus`, `diff.minus` and `diff.delta`.
Other diff providers will eventually be supported by a future plugin system.
There are currently no options for this section.
#### `[editor.gutters.spacer]` Section
Currently unused
### `[editor.soft-wrap]` Section
Options for soft wrapping lines that exceed the view width:
| Key | Description | Default |
| --- | --- | --- |
| `enable` | Whether soft wrapping is enabled. | `false` |
| `max-wrap` | Maximum free space left at the end of the line. | `20` |
| `max-indent-retain` | Maximum indentation to carry over when soft wrapping a line. | `40` |
| `wrap-indicator` | Text inserted before soft wrapped lines, highlighted with `ui.virtual.wrap` | `↪ ` |
| `wrap-at-text-width` | Soft wrap at `text-width` instead of using the full viewport size. | `false` |
Example:
```toml
[editor.soft-wrap]
enable = true
max-wrap = 25 # increase value to reduce forced mid-word wrapping
max-indent-retain = 0
wrap-indicator = "" # set wrap-indicator to "" to hide it
```
### `[editor.smart-tab]` Section
Options for navigating and editing using tab key.
| Key | Description | Default |
|------------|-------------|---------|
| `enable` | If set to true, then when the cursor is in a position with non-whitespace to its left, instead of inserting a tab, it will run `move_parent_node_end`. If there is only whitespace to the left, then it inserts a tab as normal. With the default bindings, to explicitly insert a tab character, press Shift-tab. | `true` |
| `supersede-menu` | Normally, when a menu is on screen, such as when auto complete is triggered, the tab key is bound to cycling through the items. This means when menus are on screen, one cannot use the tab key to trigger the `smart-tab` command. If this option is set to true, the `smart-tab` command always takes precedence, which means one cannot use the tab key to cycle through menu items. One of the other bindings must be used instead, such as arrow keys or `C-n`/`C-p`. | `false` |
Due to lack of support for S-tab in some terminals, the default keybindings don't fully embrace smart-tab editing experience. If you enjoy smart-tab navigation and a terminal that supports the [Enhanced Keyboard protocol](https://github.com/helix-editor/helix/wiki/Terminal-Support#enhanced-keyboard-protocol), consider setting extra keybindings:
```
[keys.normal]
tab = "move_parent_node_end"
S-tab = "move_parent_node_start"
[keys.insert]
S-tab = "move_parent_node_start"
[keys.select]
tab = "extend_parent_node_end"
S-tab = "extend_parent_node_start"
```
### `[editor.inline-diagnostics]` Section
Options for rendering diagnostics inside the text like shown below
```
fn main() {
let foo = bar;
└─ no such value in this scope
}
````
| Key | Description | Default |
|------------|-------------|---------|
| `cursor-line` | The minimum severity that a diagnostic must have to be shown inline on the line that contains the primary cursor. Set to `disable` to not show any diagnostics inline. This option does not have any effect when in insert-mode and will only take effect 350ms after moving the cursor to a different line. | `"disable"` |
| `other-lines` | The minimum severity that a diagnostic must have to be shown inline on a line that does not contain the cursor-line. Set to `disable` to not show any diagnostics inline. | `"disable"` |
| `prefix-len` | How many horizontal bars `─` are rendered before the diagnostic text. | `1` |
| `max-wrap` | Equivalent of the `editor.soft-wrap.max-wrap` option for diagnostics. | `20` |
| `max-diagnostics` | Maximum number of diagnostics to render inline for a given line | `10` |
The (first) diagnostic with the highest severity that is not shown inline is rendered at the end of the line (as long as its severity is higher than the `end-of-line-diagnostics` config option):
```
fn main() {
let baz = 1;
let foo = bar; a local variable with a similar name exists: baz
└─ no such value in this scope
}
```
The new diagnostic rendering is not yet enabled by default. As soon as end of line or inline diagnostics are enabled the old diagnostics rendering is automatically disabled. The recommended default setting are:
```
end-of-line-diagnostics = "hint"
[editor.inline-diagnostics]
cursor-line = "warning" # show warnings and errors on the cursorline inline
```

## Linux, macOS, Windows and OpenBSD packaging status
[![Packaging status](https://repology.org/badge/vertical-allrepos/helix.svg)](https://repology.org/project/helix/versions)
## Linux
The following third party repositories are available:
### Ubuntu
Add the `PPA` for Helix:
```sh
sudo add-apt-repository ppa:maveonair/helix-editor
sudo apt update
sudo apt install helix
```
### Fedora/RHEL
```sh
sudo dnf install helix
```
### Arch Linux extra
Releases are available in the `extra` repository:
```sh
sudo pacman -S helix
```
> 💡 When installed from the `extra` repository, run Helix with `helix` instead of `hx`.
>
> For example:
> ```sh
> helix --health
> ```
> to check health
Additionally, a [helix-git](https://aur.archlinux.org/packages/helix-git/) package is available
in the AUR, which builds the master branch.
### NixOS
Helix is available in [nixpkgs](https://github.com/nixos/nixpkgs) through the `helix` attribute,
the unstable channel usually carries the latest release.
Helix is also available as a [flake](https://nixos.wiki/wiki/Flakes) in the project
root. Use `nix develop` to spin up a reproducible development shell. Outputs are
cached for each push to master using [Cachix](https://www.cachix.org/). The
flake is configured to automatically make use of this cache assuming the user
accepts the new settings on first use.
If you are using a version of Nix without flakes enabled,
[install Cachix CLI](https://docs.cachix.org/installation) and use
`cachix use helix` to configure Nix to use cached outputs when possible.
### Flatpak
Helix is available on [Flathub](https://flathub.org/en-GB/apps/com.helix_editor.Helix):
```sh
flatpak install flathub com.helix_editor.Helix
flatpak run com.helix_editor.Helix
```
### Snap
Helix is available on [Snapcraft](https://snapcraft.io/helix) and can be installed with:
```sh
snap install --classic helix
```
This will install Helix as both `/snap/bin/helix` and `/snap/bin/hx`, so make sure `/snap/bin` is in your `PATH`.
### AppImage
Install Helix using the Linux [AppImage](https://appimage.org/) format.
Download the official Helix AppImage from the [latest releases](https://github.com/helix-editor/helix/releases/latest) page.
```sh

### Chocolatey
```sh
choco install helix
```
### MSYS2
For 64-bit Windows 8.1 or above:
```sh
pacman -S mingw-w64-ucrt-x86_64-helix
```
## Building from source
Requirements:
Clone the Helix GitHub repository into a directory of your choice. The
examples in this documentation assume installation into either `~/src/` on
Linux and macOS, or `%userprofile%\src\` on Windows.
- The [Rust toolchain](https://www.rust-lang.org/tools/install)
- The [Git version control system](https://git-scm.com/)
- A C++14 compatible compiler to build the tree-sitter grammars, for example GCC or Clang
If you are using the `musl-libc` standard library instead of `glibc` the following environment variable must be set during the build to ensure tree-sitter grammars can be loaded correctly:
```sh
RUSTFLAGS="-C target-feature=-crt-static"
```
1. Clone the repository:
```sh
git clone https://github.com/helix-editor/helix
cd helix
```
2. Compile from source:
```sh
cargo install --path helix-term --locked
```
This command will create the `hx` executable and construct the tree-sitter
grammars in the local `runtime` folder.
> 💡 If you do not want to fetch or build grammars, set an environment variable `HELIX_DISABLE_AUTO_GRAMMAR_BUILD`
> 💡 Tree-sitter grammars can be fetched and compiled if not pre-packaged. Fetch
> grammars with `hx --grammar fetch` and compile them with
> `hx --grammar build`. This will install them in
> the `runtime` directory within the user's helix config directory (more
> [details below](#multiple-runtime-directories)).
### Configuring Helix's runtime files
#### Linux and macOS
The **runtime** directory is one below the Helix source, so either export a
`HELIX_RUNTIME` environment variable to point to that directory and add it to
your `~/.bashrc` or equivalent:
```sh
export HELIX_RUNTIME=~/src/helix/runtime
```
Or, create a symbolic link:
```sh
ln -Ts $PWD/runtime ~/.config/helix/runtime
```
If the above command fails to create a symbolic link because the file exists either move `~/.config/helix/runtime` to a new location or delete it, then run the symlink command above again.
#### Windows
Either set the `HELIX_RUNTIME` environment variable to point to the runtime files using the Windows setting (search for
`Edit environment variables for your account`) or use the `setx` command in
Cmd:
```sh
setx HELIX_RUNTIME "%userprofile%\source\repos\helix\runtime"
```
> 💡 `%userprofile%` resolves to your user directory like
> `C:\Users\Your-Name\` for example.
Or, create a symlink in `%appdata%\helix\` that links to the source code directory:
| Method | Command |
| ---------- | -------------------------------------------------------------------------------------- |
| PowerShell | `New-Item -ItemType Junction -Target "runtime" -Path "$Env:AppData\helix\runtime"` |
| Cmd | `cd %appdata%\helix` <br/> `mklink /D runtime "%userprofile%\src\helix\runtime"` |
> 💡 On Windows, creating a symbolic link may require running PowerShell or
> Cmd as an administrator.
#### Multiple runtime directories
When Helix finds multiple runtime directories it will search through them for files in the
following order:
1. `runtime/` sibling directory to `$CARGO_MANIFEST_DIR` directory (this is intended for
developing and testing helix only).
2. `runtime/` subdirectory of OS-dependent helix user config directory.
3. `$HELIX_RUNTIME`
4. Distribution-specific fallback directory (set at compile time—not run time—
with the `HELIX_DEFAULT_RUNTIME` environment variable)
5. `runtime/` subdirectory of path to Helix executable.
This order also sets the priority for selecting which file will be used if multiple runtime
directories have files with the same name.
#### Note to packagers
If you are making a package of Helix for end users, to provide a good out of
the box experience, you should set the `HELIX_DEFAULT_RUNTIME` environment
variable at build time (before invoking `cargo build`) to a directory which
will store the final runtime files after installation. For example, say you want
to package the runtime into `/usr/lib/helix/runtime`. The rough steps a build
script could follow are:
1. `export HELIX_DEFAULT_RUNTIME=/usr/lib/helix/runtime`
1. `cargo build --profile opt --locked --path helix-term`
1. `cp -r runtime $BUILD_DIR/usr/lib/helix/`
1. `cp target/opt/hx $BUILD_DIR/usr/bin/hx`
This way the resulting `hx` binary will always look for its runtime directory in
`/usr/lib/helix/runtime` if the user has no custom runtime in `~/.config/helix`
or `HELIX_RUNTIME`.
### Validating the installation
To make sure everything is set up as expected you should run the Helix health
check:
```sh
hx --health
```
For more information on the health check results refer to
[Health check](https://github.com/helix-editor/helix/wiki/Healthcheck).
### Configure the desktop shortcut
If your desktop environment supports the
[XDG desktop menu](https://specifications.freedesktop.org/menu-spec/menu-spec-latest.html)
you can configure Helix to show up in the application menu by copying the
provided `.desktop` and icon files to their correct folders:
```sh
cp contrib/Helix.desktop ~/.local/share/applications
cp contrib/helix.png ~/.icons # or ~/.local/share/icons
```
To use another terminal than the system default, you can modify the `.desktop` 1. Add the `hx` binary to your system's `$PATH` to allow it to be used from the command line.
file. For example, to use `kitty`: 2. Copy the `runtime` directory to a location that `hx` searches for runtime files. A typical location on Linux/macOS is `~/.config/helix/runtime`.
```sh To see the runtime directories that `hx` searches, run `hx --health`. If necessary, you can override the default runtime location by setting the `HELIX_RUNTIME` environment variable.
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
```

The following third party repositories are available:
### Ubuntu
Add the `PPA` for Helix:
```sh
sudo add-apt-repository ppa:maveonair/helix-editor
sudo apt update
sudo apt install helix
```
### Fedora/RHEL
```sh
sudo dnf install helix
```
### Arch Linux extra
Releases are available in the `extra` repository:
```sh
sudo pacman -S helix
```
> 💡 When installed from the `extra` repository, run Helix with `helix` instead of `hx`.
>
> For example:
> ```sh
> helix --health
> ```
> to check health
Additionally, a [helix-git](https://aur.archlinux.org/packages/helix-git/) package is available
in the AUR, which builds the master branch.
### NixOS
Helix is available in [nixpkgs](https://github.com/nixos/nixpkgs) through the `helix` attribute,
the unstable channel usually carries the latest release.
Helix is also available as a [flake](https://wiki.nixos.org/wiki/Flakes) in the project
root. Use `nix develop` to spin up a reproducible development shell. Outputs are
cached for each push to master using [Cachix](https://www.cachix.org/). The
flake is configured to automatically make use of this cache assuming the user
accepts the new settings on first use.
If you are using a version of Nix without flakes enabled,
[install Cachix CLI](https://docs.cachix.org/installation) and use
`cachix use helix` to configure Nix to use cached outputs when possible.
### Flatpak
Helix is available on [Flathub](https://flathub.org/en-GB/apps/com.helix_editor.Helix):
```sh
flatpak install flathub com.helix_editor.Helix
flatpak run com.helix_editor.Helix
```
### Snap
Helix is available on [Snapcraft](https://snapcraft.io/helix) and can be installed with:
```sh
snap install --classic helix
```
This will install Helix as both `/snap/bin/helix` and `/snap/bin/hx`, so make sure `/snap/bin` is in your `PATH`.

## Using pickers
Helix has a variety of pickers, which are interactive windows used to select various kinds of items. These include a file picker, global search picker, and more. Most pickers are accessed via keybindings in [space mode](./keymap.md#space-mode). Pickers have their own [keymap](./keymap.md#picker) for navigation.
### Filtering Picker Results
Most pickers perform fuzzy matching using [fzf syntax](https://github.com/junegunn/fzf?tab=readme-ov-file#search-syntax). Two exceptions are the global search picker, which uses regex, and the workspace symbol picker, which passes search terms to the LSP. Note that OR operations (`|`) are not currently supported.
If a picker shows multiple columns, you may apply the filter to a specific column by prefixing the column name with `%`. Column names can be shortened to any prefix, so `%p`, `%pa` or `%pat` all mean the same as `%path`. For example, a query of `helix %p .toml !lang` in the global search picker searches for the term "helix" within files with paths ending in ".toml" but not including "lang".
You can insert the contents of a [register](./registers.md) using `Ctrl-r` followed by a register name. For example, one could insert the currently selected text using `Ctrl-r`-`.`, or the directory of the current file using `Ctrl-r`-`%` followed by `Ctrl-w` to remove the last path section. The global search picker will use the contents of the [search register](./registers.md#default-registers) if you press `Enter` without typing a filter. For example, pressing `*`-`Space-/`-`Enter` will start a global search for the currently selected text.

## Registers
- [User-defined registers](#user-defined-registers)
- [Default registers](#default-registers)
- [Special registers](#special-registers)
In Helix, registers are storage locations for text and other data, such as the
result of a search. Registers can be used to cut, copy, and paste text, similar
to the clipboard in other text editors. Usage is similar to Vim, with `"` being
used to select a register.
### User-defined registers
Helix allows you to create your own named registers for storing text, for
example:
- `"ay` - Yank the current selection to register `a`.
- `"op` - Paste the text in register `o` after the selection.
If a register is selected before invoking a change or delete command, the selection will be stored in the register and the action will be carried out:
- `"hc` - Store the selection in register `h` and then change it (delete and enter insert mode).
- `"md` - Store the selection in register `m` and delete it.
### Default registers
Commands that use registers, like yank (`y`), use a default register if none is specified.
These registers are used as defaults:
| Register character | Contains |
| --- | --- |
| `/` | Last search |
| `:` | Last executed command |
| `"` | Last yanked text |
| `@` | Last recorded macro |
### Special registers
Some registers have special behavior when read from and written to.
| Register character | When read | When written |
| --- | --- | --- |
| `_` | No values are returned | All values are discarded |
| `#` | Selection indices (first selection is `1`, second is `2`, etc.) | This register is not writable |
| `.` | Contents of the current selections | This register is not writable |
| `%` | Name of the current file | This register is not writable |
| `+` | Reads from the system clipboard | Joins and yanks to the system clipboard |
| `*` | Reads from the primary clipboard | Joins and yanks to the primary clipboard |
When yanking multiple selections to the clipboard registers, the selections
are joined with newlines. Pasting from these registers will paste multiple
selections if the clipboard was last yanked to by the Helix session. Otherwise
the clipboard contents are pasted as one selection.

There are three kinds of commands that can be used in keymaps:
* Static commands: commands like `move_char_right` which are usually bound to

in [`helix-term/src/commands.rs`](https://github.com/helix-editor/helix/blob/master/helix-term/src/commands.rs)

* Typable commands: commands that can be executed from command mode (`:`), for
example `:write!`. See the [Commands](./commands.html) documentation for a
list of available typeable commands.
* Macros: sequences of keys that are executed in order. These keybindings
start with `@` and then list any number of keys to be executed. For example
`@miw` can be used to select the surrounding word. For now, macro keybindings
are not allowed in keybinding sequences due to limitations in the way that
command sequences are executed.

## Surround
Helix includes built-in functionality similar to [vim-surround](https://github.com/tpope/vim-surround).
The keymappings have been inspired from [vim-sandwich](https://github.com/machakann/vim-sandwich):

| `mr<char_to_replace><new_char>` | Replace the closest surround characters |
| `md<char_to_delete>` | Delete the closest surround characters |
You can use counts to act on outer pairs.
Surround can also act on multiple selections. For example, to change every occurrence of `(use)` to `[use]`:
1. `%` to select the whole file
2. `s` to split the selections on a search term
3. Input `use` and hit Enter
4. `mr([` to replace the parentheses with square brackets
Multiple characters are currently not supported, but planned for future release.

## Moving the selection with syntax-aware motions
`Alt-p`, `Alt-o`, `Alt-i`, and `Alt-n` (or `Alt` and arrow keys) allow you to move the
selection according to its location in the syntax tree. For example, many languages have the
following syntax for function calls:
```js
func(arg1, arg2, arg3);
```
A function call might be parsed by tree-sitter into a tree like the following.
```tsq
(call
function: (identifier) ; func
arguments:
(arguments ; (arg1, arg2, arg3)
(identifier) ; arg1
(identifier) ; arg2
(identifier))) ; arg3
```
Use `:tree-sitter-subtree` to view the syntax tree of the primary selection. In
a more intuitive tree format:
```
┌────┐
│call│
┌─────┴────┴─────┐
│ │
┌─────▼────┐ ┌────▼────┐
│identifier│ │arguments│
│ "func" │ ┌────┴───┬─────┴───┐
└──────────┘ │ │ │
│ │ │
┌─────────▼┐ ┌────▼─────┐ ┌▼─────────┐
│identifier│ │identifier│ │identifier│
│ "arg1" │ │ "arg2" │ │ "arg3" │
└──────────┘ └──────────┘ └──────────┘
```
If you have a selection that wraps `arg1` (see the tree above), and you use
`Alt-n`, it will select the next sibling in the syntax tree: `arg2`.
```js
// before
func([arg1], arg2, arg3)
// after
func(arg1, [arg2], arg3);
```
Similarly, `Alt-o` will expand the selection to the parent node, in this case, the
arguments node.
```js
func[(arg1, arg2, arg3)];
```
There is also some nuanced behavior that prevents you from getting stuck on a
node with no sibling. When using `Alt-p` with a selection on `arg1`, the previous
child node will be selected. In the event that `arg1` does not have a previous
sibling, the selection will move up the syntax tree and select the previous
element. As a result, using `Alt-p` with a selection on `arg1` will move the
selection to the "func" `identifier`.

## Selecting and manipulating text with textobjects
In Helix, textobjects are a way to select, manipulate and operate on a piece of

their structure or purpose, such as a word, sentence, paragraph, or even a
function or block of code.

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.
`Alt-n`, it will select the next sibling in the syntax tree: `arg2`.
```js ## Multiple selections
// before
func([arg1], arg2, arg3)
// after
func(arg1, [arg2], arg3);
```
Similarly, `Alt-o` will expand the selection to the parent node, in this case, the Also inspired by Kakoune, multiple selections are a core mode of interaction in Helix. For example, the standard way of replacing multiple instance of a word is to first select all instances (so there is one selection per instance) and then use the change action (`c`) to edit them all at the same time.
arguments node.
```js ## Motions
func[(arg1, arg2, arg3)];
```
There is also some nuanced behavior that prevents you from getting stuck on a Motions are commands that move the cursor or modify selections. They're used for navigation and text manipulation. Examples include `w` to move to the next word, or `f` to find a character. See the [Movement](./keymap.md#movement) section of the keymap for more motions.
node with no sibling. When using `Alt-p` with a selection on `arg1`, the previous
child node will be selected. In the event that `arg1` does not have a previous
sibling, the selection will move up the syntax tree and select the previous
element. As a result, using `Alt-p` with a selection on `arg1` will move the
selection to the "func" `identifier`.

publishing a patch release after a major release, the `.0` is dropped in
the user facing version.
* Releases are planned to happen every two months, so `22.05.0` would change to `22.07.0`

# Helix's `lsp-types`
This is a fork of the [`lsp-types`](https://crates.io/crates/lsp-types) crate ([`gluon-lang/lsp-types`](https://github.com/gluon-lang/lsp-types)) taken at version v0.95.1 (commit [3e6daee](https://github.com/gluon-lang/lsp-types/commit/3e6daee771d14db4094a554b8d03e29c310dfcbe)). This fork focuses usability improvements that make the types easier to work with for the Helix codebase. For example the URL type - the `uri` crate at this version of `lsp-types` - will be replaced with a wrapper around a string.
