# Adding new languages to Helix
|
||||
|
||||
In order to add a new language to Helix, you will need to follow the steps
|
||||
below.
|
||||
|
||||
## Language configuration
|
||||
|
||||
To add a new language, you need to add a `[[language]]` entry to the
|
||||
`languages.toml` (see the [language configuration section]).
|
||||
1. Add a new `[[language]]` entry in the `languages.toml` file and provide the
|
||||
necessary configuration for the new language. For more information on
|
||||
language configuration, refer to the
|
||||
[language configuration section](../languages.md) of the documentation.
|
||||
A new language server can be added by extending the `[language-server]` table in the same file.
|
||||
2. If you are adding a new language or updating an existing language server
|
||||
configuration, run the command `cargo xtask docgen` to update the
|
||||
[Language Support](../lang-support.md) documentation.
|
||||
|
||||
When adding a new language or Language Server configuration for an existing
|
||||
language, run `cargo xtask docgen` to add the new configuration to the
|
||||
[Language Support][lang-support] docs before creating a pull request.
|
||||
When adding a Language Server configuration, be sure to update the
|
||||
[Language Server Wiki][install-lsp-wiki] with installation notes.
|
||||
> 💡 If you are adding a new Language Server configuration, make sure to update
|
||||
> the
|
||||
> [Language Server Wiki](https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers)
|
||||
> with the installation instructions.
|
||||
|
||||
## Grammar configuration
|
||||
|
||||
If a tree-sitter grammar is available for the language, add a new `[[grammar]]`
|
||||
entry to `languages.toml`.
|
||||
|
||||
You may use the `source.path` key rather than `source.git` with an absolute path
|
||||
to a locally available grammar for testing, but switch to `source.git` before
|
||||
submitting a pull request.
|
||||
1. If a tree-sitter grammar is available for the new language, add a new
|
||||
`[[grammar]]` entry to the `languages.toml` file.
|
||||
2. If you are testing the grammar locally, you can use the `source.path` key
|
||||
with an absolute path to the grammar. However, before submitting a pull
|
||||
request, make sure to switch to using `source.git`.
|
||||
|
||||
## Queries
|
||||
|
||||
For a language to have syntax-highlighting and indentation among
|
||||
other things, you have to add queries. Add a directory for your
|
||||
language with the path `runtime/queries/<name>/`. The tree-sitter
|
||||
[website](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#queries)
|
||||
gives more info on how to write queries.
|
||||
|
||||
> NOTE: When evaluating queries, the first matching query takes
|
||||
precedence, which is different from other editors like Neovim where
|
||||
the last matching query supersedes the ones before it. See
|
||||
[this issue][neovim-query-precedence] for an example.
|
||||
|
||||
## Common Issues
|
||||
|
||||
- If you get errors when running after switching branches, you may have to update the tree-sitter grammars. Run `hx --grammar fetch` to fetch the grammars and `hx --grammar build` to build any out-of-date grammars.
|
||||
|
||||
- If a parser is segfaulting or you want to remove the parser, make sure to remove the compiled parser in `runtime/grammar/<name>.so`

|

1. In order to provide syntax highlighting and indentation for the new language,
|
||||
you will need to add queries.
|
||||
2. Create a new directory for the language with the path
|
||||
`runtime/queries/<name>/`.
|
||||
3. Refer to the
|
||||
[tree-sitter website](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#queries)
|
||||
for more information on writing queries.
|
||||
4. A list of highlight captures can be found [on the themes page](https://docs.helix-editor.com/themes.html#scopes).

|

## Common issues
|
||||
|
||||
- If you encounter errors when running Helix after switching branches, you may
|
||||
need to update the tree-sitter grammars. Run the command `hx --grammar fetch`
|
||||
to fetch the grammars and `hx --grammar build` to build any out-of-date
|
||||
grammars.
|
||||
- If a parser is causing a segfault, or you want to remove it, make sure to
|
||||
remove the compiled parser located at `runtime/grammars/<name>.so`.
|
||||
- If you are attempting to add queries and Helix is unable to locate them, ensure that the environment variable `HELIX_RUNTIME` is set to the location of the `runtime` folder you're developing in.

|
||||
## Pre-built binaries
|
||||
|
||||
Download pre-built binaries from the
|
||||
[GitHub Releases page](https://github.com/helix-editor/helix/releases). Add the binary to your system's `$PATH` to use it from the command
|
||||
line.
|
||||
|
||||
## Linux, macOS, Windows and OpenBSD packaging status
|
||||
|
||||
[](https://repology.org/project/helix/versions)
|
||||
|
||||
## OSX
|
||||
## Linux
|
||||
|
||||
The following third party repositories are available:
|
||||
|
||||
### Ubuntu
|
||||
|
||||
Helix is available in homebrew-core:
|
||||
Add the `PPA` for Helix:
|
||||
|
||||
```sh
|
||||
sudo add-apt-repository ppa:maveonair/helix-editor
|
||||
sudo apt update
|
||||
sudo apt install helix
|
||||
```
|
||||
brew install helix
|
||||
|
||||
### Fedora/RHEL
|
||||
|
||||
```sh
|
||||
sudo dnf install helix
|
||||
```
|
||||
|
||||
## Linux
|
||||
### 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
|
||||
|
||||
A [flake](https://nixos.wiki/wiki/Flakes) containing the package is available in
|
||||
the project root. The flake can also be used to spin up a reproducible development
|
||||
shell for working on Helix with `nix develop`.
|
||||
Helix is available in [nixpkgs](https://github.com/nixos/nixpkgs) through the `helix` attribute,
|
||||
the unstable channel usually carries the latest release.
|
||||
|
||||
Flake 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.
|
||||
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 you can
|
||||
[install Cachix cli](https://docs.cachix.org/installation); `cachix use helix` will
|
||||
configure Nix to use cached outputs when possible.
|
||||
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.

|
||||
|
||||
- For 32 bit Windows 7 or above:
|
||||
|
||||
```
|
||||
pacman -S mingw-w64-i686-helix
|

## Building from source
|
||||
|
||||
```
|

pacman -S mingw-w64-x86_64-helix
|
||||
```
|
||||
Requirements:
|
||||
|
||||
- For 64 bit Windows 8.1 or above:
|
||||
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.
|
||||
|
||||
```
|
||||
pacman -S mingw-w64-ucrt-x86_64-helix
|
||||
```
|
||||
- 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
|
||||
|
||||
## Build from source
|
||||
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:
|
||||
|
||||
```
|
||||
git clone https://github.com/helix-editor/helix
|
||||
cd helix
|
||||
cargo install --path helix-term --locked
|
||||
```sh
|
||||
RUSTFLAGS="-C target-feature=-crt-static"
|
||||
```
|
||||
|
||||
This will install the `hx` binary to `$HOME/.cargo/bin` and build tree-sitter grammars in `./runtime/grammars`.
|
||||
1. Clone the repository:
|
||||
|
||||
If you are using the musl-libc instead of glibc the following environment variable must be set during the build
|
||||
to ensure tree sitter grammars can be loaded correctly:
|
||||
```sh
|
||||
git clone https://github.com/helix-editor/helix
|
||||
cd helix
|
||||
```
|
||||
|
||||
```
|
||||
RUSTFLAGS="-C target-feature=-crt-static"
|
||||
```
|
||||
2. Compile from source:
|
||||
|
||||
```sh
|
||||
cargo install --path helix-term --locked
|
||||
```
|
||||
|
||||
Helix also needs its runtime files so make sure to copy/symlink the `runtime/` directory into the
|
||||
config directory (for example `~/.config/helix/runtime` on Linux/macOS). This location can be overridden
|
||||
via the `HELIX_RUNTIME` environment variable.
|
||||
This command will create the `hx` executable and construct the tree-sitter
|
||||
grammars in the local `runtime` folder.
|
||||
|
||||
| OS | Command |
|
||||
| -------------------- | ------------------------------------------------ |
|
||||
| Windows (Cmd) | `xcopy /e /i runtime %AppData%\helix\runtime` |
|
||||
| Windows (PowerShell) | `xcopy /e /i runtime $Env:AppData\helix\runtime` |
|
||||
| Linux / macOS | `ln -s $PWD/runtime ~/.config/helix/runtime` |
|
||||
> 💡 If you do not want to fetch or build grammars, set an environment variable `HELIX_DISABLE_AUTO_GRAMMAR_BUILD`
|
||||
|
||||
Starting with Windows Vista you can also create symbolic links on Windows. Note that this requires
|
||||
elevated privileges - i.e. PowerShell or Cmd must be run as administrator.
|
||||
> 💡 Tree-sitter grammars can be fetched and compiled if not pre-packaged. Fetch
|
||||
> grammars with `hx --grammar fetch` and compile them with
|
||||
> `hx --grammar build`. This will install them in
|
||||
> the `runtime` directory within the user's helix config directory (more
|
||||
> [details below](#multiple-runtime-directories)).
|
||||
|
||||
**PowerShell:**
|
||||
### Configuring Helix's runtime files
|
||||
|
||||
```powershell
|
||||
New-Item -ItemType Junction -Target "runtime" -Path "$Env:AppData\helix\runtime"
|
||||
```
|
||||
Note: "runtime" must be the absolute path to the runtime directory.
|
||||
#### Linux and macOS
|
||||
|
||||
**Cmd:**
|
||||
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:
|
||||
|
||||
```cmd
|
||||
cd %appdata%\helix
|
||||
mklink /D runtime "<helix-repo>\runtime"
|
||||
```sh
|
||||
export HELIX_RUNTIME=~/src/helix/runtime
|
||||
```
|
||||
|
||||
The runtime location can be overridden via the `HELIX_RUNTIME` environment variable.
|
||||
Or, create a symbolic link:
|
||||
|
||||
```sh
|
||||
ln -Ts $PWD/runtime ~/.config/helix/runtime
|
||||
```
|
||||
|
||||
> NOTE: if `HELIX_RUNTIME` is set prior to calling `cargo install --path helix-term --locked`,
|
||||
> tree-sitter grammars will be built in `$HELIX_RUNTIME/grammars`.
|
||||
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.
|
||||
|
||||
If you plan on keeping the repo locally, an alternative to copying/symlinking
|
||||
runtime files is to set `HELIX_RUNTIME=/path/to/helix/runtime`
|
||||
(`HELIX_RUNTIME=$PWD/runtime` if you're in the helix repo directory).
|
||||
#### Windows
|
||||
|
||||
To use Helix in desktop environments that supports [XDG desktop menu](https://specifications.freedesktop.org/menu-spec/menu-spec-latest.html), including Gnome and KDE, copy the provided `.desktop` file to the correct folder:
|
||||
Either set the `HELIX_RUNTIME` environment variable to point to the runtime files using the Windows setting (search for
|
||||
`Edit environment variables for your account`) or use the `setx` command in
|
||||
Cmd:
|
||||
|
||||
```bash
|
||||
cp contrib/Helix.desktop ~/.local/share/applications
|
||||
```sh
|
||||
setx HELIX_RUNTIME "%userprofile%\source\repos\helix\runtime"
|
||||
```
|
||||
|
||||
To use another terminal than the default, you will need to modify the `.desktop` file. For example, to use `kitty`:
|
||||
> 💡 `%userprofile%` resolves to your user directory like
|
||||
> `C:\Users\Your-Name\` for example.
|
||||
|
||||
```bash
|
||||
sed -i "s|Exec=hx %F|Exec=kitty hx %F|g" ~/.local/share/applications/Helix.desktop
|
||||
sed -i "s|Terminal=true|Terminal=false|g" ~/.local/share/applications/Helix.desktop
|
||||
```
|
||||
Or, create a symlink in `%appdata%\helix\` that links to the source code directory:
|
||||
|
||||
Please note: there is no icon for Helix yet, so the system default will be used.
|
||||
| Method | Command |
|
||||
| ---------- | -------------------------------------------------------------------------------------- |
|
||||
| PowerShell | `New-Item -ItemType Junction -Target "runtime" -Path "$Env:AppData\helix\runtime"` |
|
||||
| Cmd | `cd %appdata%\helix` <br/> `mklink /D runtime "%userprofile%\src\helix\runtime"` |
|
||||
|
||||
## Finishing up the installation
|
||||
> 💡 On Windows, creating a symbolic link may require running PowerShell or
|
||||
> Cmd as an administrator.
|
||||
|
||||
To make sure everything is set up as expected you should finally run the helix healthcheck via
|
||||
#### 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 information displayed in the health check results refer to [Healthcheck](https://github.com/helix-editor/helix/wiki/Healthcheck).
|
||||
For more information on the health check results refer to
|
||||
[Health check](https://github.com/helix-editor/helix/wiki/Healthcheck).
|
||||
|
||||
### Configure the desktop shortcut
|
||||
|
||||
### Building tree-sitter grammars
|
||||
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:
|
||||
|
||||
Tree-sitter grammars must be fetched and compiled if not pre-packaged.
|
||||
Fetch grammars with `hx --grammar fetch` (requires `git`) and compile them
|
||||
with `hx --grammar build` (requires a C++ compiler).
|
||||
```sh
|
||||
cp contrib/Helix.desktop ~/.local/share/applications
|
||||
cp contrib/helix.png ~/.icons # or ~/.local/share/icons
|
||||
```
|
||||
|
||||
### Installing language servers
|
||||
To use another terminal than the system default, you can modify the `.desktop`
|
||||
file. For example, to use `kitty`:
|
||||
|
||||
Language servers can optionally be installed if you want their features (auto-complete, diagnostics etc.).
|
||||
Follow the [instructions on the wiki page](https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers) to add your language servers of choice.
|
||||
```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
|
||||

//! `helix-event` contains systems that allow (often async) communication between
|
||||
//! 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.
