Add object selection (textobjects) (#385)
* Add textobjects for word

* Add textobjects for surround characters

* Apply clippy lints

* Remove ThisWordPrevBound in favor of PrevWordEnd

It's the same as PrevWordEnd except for taking the current char
into account, so use a "flag" to capture that usecase

* Add tests for PrevWordEnd movement

* Remove ThisWord* movements

They did not preserve anchor positions and were only used
for textobject boundary search anyway so replace them with
simple position finding functions

* Rewrite tests of word textobject

* Add tests for surround textobject

* Add textobject docs

* Refactor textobject word position functions

* Apply clippy lints on textobject

* Fix overflow error with textobjects

Helix

Build status

Screenshot

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/<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 config directory or the same directory as executable, but that can be overriden via the HELIX_RUNTIME environment variable.

NOTE: running via cargo doesn't require setting explicit HELIX_RUNTIME path, it will automatically detect the runtime directory in the project root.

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"

Packaging status

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.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 vs 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 that should give you a good overview of the internals.
