pre-commit/action
|
|
=================
|
|
|
|
a GitHub action to run [pre-commit](https://pre-commit.com)
|
|
|
|
### using this action
|
|
|
|
To use this action, make a file `.github/workflows/pre-commit.yml`. Here's a
|
|
template to get started:
|
|
|
|
```yaml
|
|
name: pre-commit
|
|
|
|
on:
|
|
pull_request:
|
|
push:
|
|
branches: [master]
|
|
|
|
jobs:
|
|
pre-commit:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@v1
|
|
- uses: actions/setup-python@v1
|
|
- name: set PY
|
|
run: echo "::set-env name=PY::$(python -c 'import hashlib, sys;print(hashlib.sha256(sys.version.encode()+sys.executable.encode()).hexdigest())')"
|
|
- uses: actions/cache@v1
|
|
with:
|
|
path: ~/.cache/pre-commit
|
|
key: pre-commit|${{ env.PY }}|${{ hashFiles('.pre-commit-config.yaml') }}
|
|
- uses: pre-commit/action@v1.0.1
|
|
```
|
|
|
|
This does a few things:
|
|
|
|
- clones the code
|
|
- installs python
|
|
- sets up the `pre-commit` cache
|
|
|
|
Hopefully in the future when `actions` matures the yaml can be simplified.
|
|
|
|
### using this action in private repositories
|
|
|
|
this action also provides an additional behaviour when used in private
|
|
repositories. when configured with a github token, the action will push back
|
|
fixes to the pull request branch.
|
|
|
|
here's an example configuration for that (use the template above except for the
|
|
`pre-commit` action):
|
|
|
|
```yaml
|
|
- uses: pre-commit/action@v1.0.1
|
|
with:
|
|
token: ${{ secrets.GITHUB_TOKEN }}
|
|
```
|
|
|
|
note that `secrets.GITHUB_TOKEN` is automatically provisioned and will not
|
|
require any special configuration.
|
|
|
|
while you could _technically_ configure this for a public repository (using a
|
|
personal access token), I can't think of a way to do this safely without
|
|
exposing a privileged token to pull requests -- if you have any ideas, please
|
|
leave an issue!
