Inserting these with the `HashMap::insert` method evades the call
to `Selection::ensure_invariants`. The effect is that the scratch
buffer (or other buffers opened through these code-paths) can start
with a selection at (0, 0), when a file with equivalent contents ("\n")
would start with (0, 1).
I.e.:
hx
and
touch f
hx f
start with different selections even though they have an equivalent
Rope. With this change they both start with (0, 1).

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
