# Helix

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.

Note: Only certain languages have indentation definitions at the moment. Check
`runtime/queries/<lang>/` for `indents.toml`.

# Installation

We provide packaging for various distributions, but here's a quick method to
build from source.

```
git clone https://github.com/helix-editor/helix
cd helix
cargo install --path helix-term
hx --grammar fetch
hx --grammar build
```

This will install the `hx` binary to `$HOME/.cargo/bin` and build tree-sitter grammars.

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, or `%AppData%/helix/runtime` on Windows).
This location can be overridden via the `HELIX_RUNTIME` environment variable.

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.
