⚠️ This repository is archived. Instead of depending on this repository, define hooks locally in your .pre-commit-config.yaml.

repos:
  - repo: local
    hooks:
      - id: scalafmt
        name: scalafmt
        entry: bash -c 'scala-cli fmt -- "$@" && git add "$@"' --
        language: system
        files: '\.(scala|sbt)$'
        stages: [pre-commit]

This runs [scala-cli fmt](https://scala-cli.virtuslab.org/docs/commands/fmt/) when .scala or .sbt files are staged, then re-stages only those files. Works reliably with renames and deletions.

Legacy hooks (this repository)

The hooks below are still functional but no longer maintained.

• sbt-fatal-warnings - turns on -Xfatal-warnings, runs a clean compilation on the given scope.

• sbt-unused-imports - as above, but also adds the "unused imports" warning.

• scalafmt-check - runs scalafmt --mode=changed --test.

• scalafmt-autofix - runs scalafmt --mode=changed and automatically stages the reformatted files.

Known issue: --mode=changed fails when staged files include renames (git mv).
