This change removes language server configuration from the default languages.toml config for integration tests. No integration-tests currently depend on the availability of a language server but if any future test needs to, it may provide a language server configuration by passing an override into the `test_syntax_conf` helper. Language-servers in integration tests cause false-positive failures when running integration tests in GitHub Actions CI. The Windows runner appears to have `clangd` installed and all OS runners have the `R` binary installed but not the `R` language server package. If a test file created by `tempfile::NamedTempFile` happens to have a file extension of `r`, the test will most likely fail because the R language server will fail to start and will become a broken pipe, meaning that it will fail to shutdown within the timeout, causing a false-positive failure. This happens surprisingly often in practice. Language servers (especially rust-analyzer) also emit unnecessary log output when initializing, which this change silences. |

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.
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 $PWD/runtime ~/.config/helix/runtime |
Starting with Windows Vista you can also create symbolic links on Windows. Note that this requires elevated priviliges - i.e. PowerShell or Cmd must be run as administrator.
PowerShell:
New-Item -ItemType SymbolicLink -Target "runtime" -Path "$Env:AppData\helix\runtime"
Cmd:
cd %appdata%\helix
mklink /D runtime "<helix-repo>\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.
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 for a language.
Adding Helix to your desktop environment
If installing from source, to use Helix in desktop environments that supports XDG desktop menu, including Gnome and KDE, copy the provided .desktop
file to the correct folder:
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
:
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
