If the close method fails, the editor will quit before restoring the terminal. This causes the shell to break if, e.g. the LS times out shutting down. This fixes this by always restoring the terminal after closing, and printing out a message to stderr if there is an error. |

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 or documentation.
All shortcuts/keymaps can be found in the documentation on the website.
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).
If you would like to build from source:
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.
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
.
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).
OS | Command |
---|---|
Windows (cmd.exe) | 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 |
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 theruntime
directory in the project root.
In order to use LSP features like auto-complete, you will need to install the appropriate Language Server for a language.
MacOS
Helix can be installed on MacOS through homebrew:
brew install helix
