Minimal git hook to run ast-grep based on the pre-commit framework.

Add this to your .pre-commit-config.yaml:

 - repo: https://github.com/boidolr/ast-grep-pre-commit rev: 0.40.3 # Use the ref you want to point at hooks: - id: ast-grep 

Note that, by default, only rules with a severity of "error" will lead to the commit hook failing. If you wish to handle rules differently, set their error level in the rule configuration or via --error.

 - repo: https://github.com/boidolr/ast-grep-pre-commit rev: 0.40.3 hooks: - id: ast-grep args: ["--update-all"] 

 - repo: https://github.com/boidolr/ast-grep-pre-commit rev: 0.40.3 hooks: - id: ast-grep args: ["--config", "/some/path/sgconfig.yaml"] 

The hook version mirrors the version of ast-grep. If for any reason you want up- or downgrade the ast-grep version used by the hook, for example to get an update before the hook was published, you can do so:

 - repo: https://github.com/boidolr/ast-grep-pre-commit rev: 0.40.3 hooks: - id: ast-grep additional_dependencies: ["@ast-grep/cli@0.38.1"] # set the desired version
