Setup pre-commit hooks

Add the following to your .pre-commit-config.yaml:

repos:
- repo: https://github.com/junghoon-vans/pre-coursier
  rev: v0.2.0
  hooks:
  - id: scalafmt
    args: ["--config-str", "version = 3.7.14, runner.dialect = scala3"]

Install pre-commit

pre-commit install

Run pre-commit

git add . # Add changes
git commit -m "Run pre-commit"

This will run scalafmt on all *.scala|*.sc|*.sbt files.

By default, the version of the hook is set to the latest version.

How to downgrade the version of the hook

This feature is only available for libraries in coursier default channel and requires pre-commit 3.0.0+.

If you want to override the version of the hook, you can set the version of the hook to run with the additional_dependencies option.

repos:
- repo: https://github.com/junghoon-vans/pre-coursier
  rev: v0.2.0
  hooks:
  - id: scalafmt
    args: ["--config-str", "version = 2.4.2, runner.dialect = scala3"]
    additional_dependencies: ["scalafmt:2.4.2"] # Override the version
