Inserting a newline currently collapses any connected selections when inserting or appending. It's happening because we're reducing the selections down to their cursors (`let selection = ..` line) and then computing the new selection based on the cursor. We're discarding the original head and anchor information which are necessary to emulate Kakoune's behavior. In Kakoune, inserting a newline retains the existing selection and _slides_ it (moves head and anchor by the same amount) forward by the newline and indentation amount. Appending a newline extends the selection to include the newline and any new indentation. With the implementation of insert_newline here, we slide by adding the global and local offsets to both head and anchor. We extend by adding the global offset to both head and anchor but the local offset only to the head. |

README.md
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
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).
| OS | command |
|---|---|
| windows | xcopy runtime %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_RUNTIMEpath, it will automatically detect theruntimedirectory 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 via:
brew tap helix-editor/helix
brew install helix
