pre-commit

alint ships a pre-commit hook definition. Add it to your .pre-commit-config.yaml:

repos:
  - repo: https://github.com/asamarts/alint
    rev: v0.9.20
    hooks:
      - id: alint

The alint hook runs alint check against the repo’s .alint.yml on every commit, blocking commits whose changes introduce errors.

Auto-fix on demand

A second hook id, alint-fix, applies fixers. It’s registered under stages: [manual] so it does not run on every commit (fixers mutate the working tree). Invoke explicitly:

pre-commit run alint-fix --all-files

Recommended config

Pin to a tagged release. Updating the rev: is how you upgrade alint:

repos:
  - repo: https://github.com/asamarts/alint
    rev: v0.9.20
    hooks:
      - id: alint
        # Pass extra args here if you need to:
        args: ["--fail-on-warning"]

The hook uses language: rust, so pre-commit handles toolchain installation transparently — zero setup for pre-commit users.
