[question] How to get staged files parameter?

describe your issue

First, thank you for making such a useful framework.

I currently use custom hooks to run prettier and eslint. The reason why I didn’t use the supported hooks is that I already have commands for them, and didn’t want to rely on supported hooks. When custom hooks are used, I cannot find a way to get staged files parameter in .pre-commit-config.yaml. Are there any ways to do that?

pre-commit --version

2.20.0

.pre-commit-config.yaml

pos:
   - repo: local
     hooks:
       - id: js-lint-check
         name: JS Lint
         entry: bash -c 'make check-eslint check-prettier'
         language: system
         files: 'webui/react/src/'
         types_or: [javascript, jsx, ts, tsx]
         pass_filenames: false

check-eslint runs eslint **/.{js,ts,tsx,jsx} and check-prettier runs prettier --check **/.{js,ts,tsx,jsx} However, I wanna run commands only for staged files instead of entire project directory

~/.cache/pre-commit/pre-commit.log (if present)

No response

every supported hook ~usually runs with pass_filenames: true (because that’s the default) so you can look at the multitudes of examples there

Ah I missed that. When I ran the pre-commit run --all-files, I got errors, so I put it to make it silent. Could you please give me an example to get filenames to commands when pass_filenames: true?
