|
||||
|
||||
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`
|
||||
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
|
||||
```

|
||||
|
||||
[^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 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`
|

|
||||
|`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 |
|
||||
|--|--|---------|
|
||||
| `focus-lost` | Enable automatic saving on the focus moving away from Helix. Requires [focus event support](https://github.com/helix-editor/helix/wiki/Terminal-Support) from your terminal | `false` |
|
||||
| `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 = "⍽"
|
||||
nnbsp = "␣"
|
||||
tab = "→"
|
||||
newline = "⏎"
|
||||
tabpad = "·" # Tabs will look like "→···" (depending on tab width)
|
||||
```
|
||||
|
||||
### `[editor.indent-guides]` Section
|
||||
|
||||
Options for rendering vertical 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"
|
||||
```

||||
|
||||
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):

## 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.

## 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):
|
||||
|
||||
|
||||
|
||||
| Key Sequence | Action |
|
||||
| --------------------------------- | --------------------------------------- |
|
||||
| `ms<char>` (after selecting text) | Add surround characters to selection |
|
||||
| `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
|
||||
text in a structured way. They allow you to refer to blocks of text based on
|
||||
their structure or purpose, such as a word, sentence, paragraph, or even a
|
||||
function or block of code.
|
||||
|
||||
|
||||
|
||||
|
||||
- `ma` - Select around the object (`va` in Vim, `<alt-a>` in Kakoune)
|
||||
- `mi` - Select inside the object (`vi` in Vim, `<alt-i>` in Kakoune)
|
||||
|
||||
| Key after `mi` or `ma` | Textobject selected |
|
||||
| --- | --- |
|
||||
| `w` | Word |
|
||||
| `W` | WORD |
|
||||
| `p` | Paragraph |
|
||||
| `(`, `[`, `'`, etc. | Specified surround pairs |
|
||||
| `m` | The closest surround pair |
|
||||
| `f` | Function |
|
||||
| `t` | Type (or Class) |
|
||||
| `a` | Argument/parameter |
|
||||
| `c` | Comment |
|
||||
| `T` | Test |
|
||||
| `g` | Change |
|
||||
|
||||
> 💡 `f`, `t`, etc. need a tree-sitter grammar active for the current
|
||||
document and a special tree-sitter query file to work properly. [Only
|
||||
some grammars](./lang-support.md) currently have the query file implemented.
|
||||
Contributions are welcome!
|
||||
|
||||
## Navigating using tree-sitter textobjects
|
||||
|
||||
Navigating between functions, classes, parameters, and other elements is
|
||||
possible using tree-sitter and textobject queries. For
|
||||
example to move to the next function use `]f`, to move to previous
|
||||
type use `[t`, and so on.
|
||||
|
