GitHub Action
- Create a new file in your repository called
.github/workflows/mega-linter.yml
- Copy the example workflow from below into that new file, no extra configuration required
- Commit that file to a new branch
- Open up a pull request and observe the action working
- Enjoy your more stable, and cleaner code base
NOTES:
- If you pass the Environment variable
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
in your workflow, then the MegaLinter will mark the status of each individual linter run in the Checks section of a pull request. Without this you will only see the overall status of the full run. There is no need to set the GitHub Secret as it's automatically set by GitHub, it only needs to be passed to the action. - You can also use it outside of GitHub Actions (CircleCI, Azure Pipelines, Jenkins, GitLab, or even locally with a docker run) , and have status on Github Pull Request if
GITHUB_TARGET_URL
environment variable exists.
In your repository you should have a .github/workflows
folder with GitHub Action similar to below:
.github/workflows/mega-linter.yml
This file should have this code
