Lefthook
Fast Git hooks manager for any language or project
About Lefthook
Lefthook is a single dependency-free binary, written in Go, that manages Git hooks for projects in any language. Hooks are declared in one YAML file and can run commands in parallel, filter files by glob or regexp, run scripts or Docker commands, and be shared across a team so checks like linters and formatters run identically on every commit and push.
