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

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

|
||||
|
||||
### `[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`

|
||||
|`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.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 |
|
||||
| --- | --- | --- |

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

|
||||
|
||||
### Ubuntu
|
||||
|
||||
Add the `PPA` for Helix:
|
||||
|
||||
```sh
|
||||
sudo add-apt-repository ppa:maveonair/helix-editor
|
||||
sudo apt update
|
||||

|
||||
```
|
||||
|
||||
### 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.
|
||||
|
||||

## 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.

## 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.
|
||||
|
||||
|
||||
|
||||
For the full reference see the [unimpaired](./keymap.html#unimpaired) section of the key bind
|
||||
documentation.
|
||||
|
||||
> 💡 This feature relies on tree-sitter textobjects
|
||||
> and requires the corresponding query file to work properly.

//! `helix-event` contains systems that allow (often async) communication between
|
||||
//! different editor components without strongly coupling them. Currently this
|
||||
//! crate only contains some smaller facilities but the intend is to add more
|
||||
//! functionality in the future ( like a generic hook system)
|
||||
//! different editor components without strongly coupling them. Specifically
|
||||
//! it allows defining synchronous hooks that run when certain editor events
|
||||
//! occur.
|
||||
//!
|
||||
//! The core of the event system are hook callbacks and the [`Event`] trait. A
|
||||
//! hook is essentially just a closure `Fn(event: &mut impl Event) -> Result<()>`
|
||||
//! that gets called every time an appropriate event is dispatched. The implementation
|
||||
//! details of the [`Event`] trait are considered private. The [`events`] macro is
|
||||
//! provided which automatically declares event types. Similarly the `register_hook`
|
||||
//! macro should be used to (safely) declare event hooks.
|
||||
//!
|
||||
//! Hooks run synchronously which can be advantageous since they can modify the
|
||||
//! current editor state right away (for example to immediately hide the completion
|
||||
//! popup). However, they can not contain their own state without locking since
|
||||
//! they only receive immutable references. For handler that want to track state, do
|
||||
//! expensive background computations or debouncing an [`AsyncHook`] is preferable.
|
||||
//! Async hooks are based around a channels that receive events specific to
|
||||
//! that `AsyncHook` (usually an enum). These events can be sent by synchronous
|
||||
//! hooks. Due to some limitations around tokio channels the [`send_blocking`]
|
||||
//! function exported in this crate should be used instead of the builtin
|
||||
//! `blocking_send`.
|
||||
//!
|
||||
//! In addition to the core event system, this crate contains some message queues
|
||||
//! that allow transfer of data back to the main event loop from async hooks and
|
||||
//! hooks that may not have access to all application data (for example in helix-view).
|
||||
//! This include the ability to control rendering ([`lock_frame`], [`request_redraw`]) and
|
||||
//! display status messages ([`status`]).
|
||||
//!
|
||||
//! Hooks declared in helix-term can furthermore dispatch synchronous jobs to be run on the
|
||||
//! main loop (including access to the compositor). Ideally that queue will be moved
|
||||
//! to helix-view in the future if we manage to detach the compositor from its rendering backend.

# 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.
