# 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.
|
|
|
|
For more information, see the [website](https://helix-editor.com) or
|
|
[documentation](https://docs.helix-editor.com/).
|
|

|
All shortcuts/keymaps can be found [in the documentation on the website](https://docs.helix-editor.com/keymap.html)

# 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.
|
|
|
|
# Installation
|
|
|
|
Note: Only certain languages have indentation definitions at the moment. Check
|
|
`runtime/<lang>/` for `indents.toml`.
|
|
|
|
We provide packaging for various distributions, but here's a quick method to
|
|
build from source.
|
|
|
|
```
|
|
git clone --recurse-submodules --shallow-submodules -j8 https://github.com/helix-editor/helix
|
|
cd helix
|
|
cargo install --path helix-term
|
|
```
|
|
|
|
This will install the `hx` binary to `$HOME/.cargo/bin`.
|
|
|
|
Now copy the `runtime/` directory somewhere. Helix will by default look for the
|
|
runtime inside the same folder as the executable, but that can be overriden via
|
|
the `HELIX_RUNTIME` environment variable.
|
|
|
|
> NOTE: You should set this to <path to repository>/runtime in development (if
|
|
> running via cargo).
|
|
>
|
|
> `export HELIX_RUNTIME=$PWD/runtime`
|
|
|
|
If you want to embed the `runtime/` directory into the Helix binary you can build
|
|
it with:
|
|
|
|
```
|
|
cargo install --path helix-term --features "embed_runtime"
|
|
```
|
|
|
|
## Arch Linux
|
|
There are two packages available from AUR:
|
|
- `helix-bin`: contains prebuilt binary from GitHub releases
|
|
- `helix-git`: builds the master branch of this repository
|
|
|
|
## MacOS
|
|
Helix can be installed on MacOS through homebrew via:
|
|
|
|
```
|
|
brew tap helix-editor/helix
|
|
brew install helix
|
|
```

# Contributing
|
|
|
|
Contributors are very welcome! **No contribution is too small and all contributions are valued.**
|
|
|
|
Some suggestions to get started:
|
|
|
|
- You can look at the [good first issue](https://github.com/helix-editor/helix/labels/good%20first%20issue) label on the issue tracker.
|
|
- Help with packaging on various distributions needed!
|
|
- To use print debugging to the `~/.cache/helix/helix.log` file, you must:
|
|
* Print using `log::info!`, `warn!`, or `error!`. (`log::info!("helix!")`)
|
|
* Pass the appropriate verbosity level option for the desired log level. (`hx -v <file>` for info, more `v`s for higher severity inclusive)
|
|
- If your preferred language is missing, integrating a tree-sitter grammar for
|
|
it and defining syntax highlight queries for it is straight forward and
|
|
doesn't require much knowledge of the internals.
|
|
|
|
We provide an [architecture.md](./docs/architecture.md) that should give you
|
|
a good overview of the internals.
