finding hooks ¶

it's recommended to use your favorite searching tool to find existing hooks to use in your project.

for example, here's some searches you may find useful using sourcegraph:

• hooks which run on python files: file:^\.pre-commit-hooks\.yaml$ "types: [python]"
• hooks which run on shell files: file:^\.pre-commit-hooks\.yaml$ "types: [shell]"
• pre-commit configurations in popular projects: file:^\.pre-commit-config\.yaml$

you may also find github's search useful as well, though its querying and sorting capabilities are quite limited plus it requires a login:

• repositories providing hooks: path:.pre-commit-hooks.yaml language:YAML

adding to this page ¶

the previous iteration of this page was a laundry list of hooks and maintaining quality of the listed tools was cumbersome.

this page is not intended to be exhaustive

you may send a pull request to expand this list however there are a few requirements you must follow or your PR will be closed without comment:

• the tool must already be fairly popular (>500 stars)
• the tool must use a managed language (no unsupported / unsupported_script / docker hooks)
• the tool must operate on files
