As discussed in #809 ; I also have a [tree-sitter implementation](https://github.com/jamesnvc/tree-sitter-prolog), but for reasons discussed in the linked post, I kind of gave up on that sort of static approach for making a general-purpose Prolog grammar (since it has a very flexible syntax and allows defining new operators with new precedences dynamically). That being said, the LSP implementation here at least shows documentation and does support the semantic token API, so when Helix supports that, this should also provide highlighting. |

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.
Installation
Note: Only certain languages have indentation definitions at the moment. Check
runtime/queries/<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.
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). This location can be overriden
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_RUNTIMEpath, it will automatically detect theruntimedirectory in the project root.
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 label on the issue tracker.
- Help with packaging on various distributions needed!
- To use print debugging to the
~/.cache/helix/helix.logfile, you must:- Print using
log::info!,warn!, orerror!. (log::info!("helix!")) - Pass the appropriate verbosity level option for the desired log level. (
hx -v <file>for info, morevs for higher severity inclusive)
- Print using
- 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 that should give you a good overview of the internals.
Getting help
Discuss the project on the community Matrix Space (make sure to join #helix-editor:matrix.org if you're on a client that doesn't support Matrix Spaces yet).
