# Helix
|
|
|
|
[](https://github.com/helix-editor/helix/actions)
|
|
|
|
|
|
|
|
A Kakoune / Neovim inspired editor, written in Rust.
|
|
|
|
The editing model is very heavily based on Kakoune; during development I found
|
|
myself agreeing with most of Kakoune's design decisions.
|
|
|
|

|

# Features
|
|
|
|
- Vim-like modal editing
|
|
- Multiple selections
|
|
- Built-in language server support
|
|
- Smart, incremental syntax highlighting and code editing via tree-sitter
|
|
|
|
It's a terminal-based editor first, but I'd like to explore a custom renderer
|
|
(similar to Emacs) in wgpu or skulpin.
|
|
|
|
Note: Only certain languages have indentation definitions at the moment. Check
|
|
`runtime/queries/<lang>/` for `indents.scm`.
|
|

|
# Installation
|
|
|
|
Packages are available for various distributions (see [Installation docs](https://docs.helix-editor.com/install.html)).
|
|
|
|
If you would like to build from source:
|
|
|
|
```shell
|
|
git clone https://github.com/helix-editor/helix
|
|
cd helix
|
|
cargo install --path helix-term
|
|
```
|
|
|
|
This will install the `hx` binary to `$HOME/.cargo/bin` and build tree-sitter grammars in `./runtime/grammars`.
|
|
|
|
Helix 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, or `%AppData%/helix/runtime` on Windows).
|
|
|
|
| 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 $PWD/runtime ~/.config/helix/runtime` |
|
|
|
|
Starting with Windows Vista you can also create symbolic links on Windows. Note that this requires
|
|
elevated privileges - i.e. PowerShell or Cmd must be run as administrator.
|
|
|
|
**PowerShell:**
|
|
|
|
```powershell
|
|
New-Item -ItemType SymbolicLink -Target "runtime" -Path "$Env:AppData\helix\runtime"
|
|
```
|
|
|
|
**Cmd:**
|
|
|
|
```cmd
|
|
cd %appdata%\helix
|
|
mklink /D runtime "<helix-repo>\runtime"
|
|
```
|
|
|
|
The runtime location can be overridden via the `HELIX_RUNTIME` environment variable.
|
|
|
|
> NOTE: if `HELIX_RUNTIME` is set prior to calling `cargo install --path helix-term`,
|
|
> tree-sitter grammars will be built in `$HELIX_RUNTIME/grammars`.
|
|
|
|
If you plan on keeping the repo locally, an alternative to copying/symlinking
|
|
runtime files is to set `HELIX_RUNTIME=/path/to/helix/runtime`
|
|
(`HELIX_RUNTIME=$PWD/runtime` if you're in the helix repo directory).
|
|
|
|
Packages already solve this for you by wrapping the `hx` binary with a wrapper
|
|
that sets the variable to the install dir.
|
|
|
|
> NOTE: running via cargo also doesn't require setting explicit `HELIX_RUNTIME` path, it will automatically
|
|
> detect the `runtime` directory in the project root.
|
|
|
|
If you want to customize your `languages.toml` config,
|
|
tree-sitter grammars may be manually fetched and built with `hx --grammar fetch` and `hx --grammar build`.
|
|
|
|
In order to use LSP features like auto-complete, you will need to
|
|
[install the appropriate Language Server](https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers)
|
|
for a language.

## Adding Helix to your desktop environment
|
|
|
|
If installing from source, 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:
|
|
|
|
```bash
|
|
cp contrib/Helix.desktop ~/.local/share/applications
|
|
```
|
|
|
|
To use another terminal than the default, you will need to modify the `.desktop` file. For example, to use `kitty`:
|
|
|
|
```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
|
|
```
|
|
|
|
Please note: there is no icon for Helix yet, so the system default will be used.
|
|
|
|
## MacOS
|
|
|
|
Helix can be installed on MacOS through homebrew:
|
|
|
|
```
|
|
brew install helix
|
|
```
