Features

• Vim-like modal editing
• Multiple selections
• Built-in language server support
• Smart, incremental syntax highlighting and code editing via tree-sitter

Build from source

Helice is built and used from a source checkout with Cargo. Install the Rust toolchain, Git, and a C++14-compatible compiler for tree-sitter grammars.

git clone https://forge.ltfourrier.net/laurent/helice
cd helice
cargo build --release --locked --manifest-path helice-term/Cargo.toml

For development, run the editor directly from the checkout:

cargo run --manifest-path helice-term/Cargo.toml -- path/to/file

To install the editor with Cargo:

cargo install --path helice-term --locked

The installed editor is invoked as hlc. Runtime files are in runtime/ in the checkout. If needed, set HELICE_RUNTIME to that directory or place a runtime link at ~/.config/helice/runtime.
