A blazing fast, robust, multi-line shell line editor written in Rust. Designed as a modern, high-performance alternative to ble.sh.

• Zero-latency asynchronous-like syntax highlighting.
• Transactional Undo/Redo: Grouped actions (no more undoing single characters).
• Fuzzy Tab Completion: Intelligent command and path completion with skim fuzzy matching algorithm.
• Fish-like Auto Suggestions: Intelligent ghost text based on your command history.
• Modal Editing: Emacs and Vi (Normal/Insert) key bindings.
• Multi-line Terminal Wrapping: Gracefully handles long commands that wrap across terminal rows.

dnf copr enable sisyphuscode/blerust
dnf install blerust

After installing, run the setup command once to add blerust to your shell:

blerust --install

Then restart your terminal or source your shell config:

source ~/.bashrc

cargo build --release
sudo install -m 755 target/release/blerust /usr/local/bin/blerust
blerust --install
source ~/.bashrc

The blerust --install command appends the following initialization snippet to ~/.bashrc:

# blerust initialization
if [[ $- == *i* && ${BLERUST_CHILD:-0} != 1 ]]; then exec blerust; fi

This replaces your interactive bash session with blerust on login, while keeping subshells (commands run by blerust itself) unaffected via the BLERUST_CHILD guard.

cargo build --release

cargo run --release
