Barad-dûr

A project-agnostic file watcher that runs your check pipeline on every save and surfaces failures before CI does. The same pipeline runs as a one-shot (baraddur check) or as a gate around another command (baraddur gate git push), so the rules you tune for save-time also gate your commits and pushes.

Install

cargo install baraddur

Pre-built binaries, source builds, and other platforms: see docs/install.md.

Quick start

baraddur init   # writes .baraddur.toml in the current directory
baraddur        # start watching

baraddur runs the pipeline immediately on launch, then re-runs it on every file change. Steps are killed and restarted if a file changes mid-run.
