The GitHub Super-Linter project is a fantastic way to lint all your file types with a single GitHub Actions Workflow. A great way to implement it everywhere is to use GHA's Reusable Workflows (see below).

My video walkthrough of this repository

This repo is part of a group of my sample repos on GitHub Actions:

• bretfisher/github-actions-templates - Main repo
• (you are here) bretfisher/super-linter-workflow - Reusable linter workflow
• bretfisher/docker-build-workflow- Reusable docker build workflow

• All the features of Super-Linter in a Reusable Workflow.
• Bonus: Optionally turn off non-DevOps linters (CSS, JS, HTML, etc.) when you want to ignore code (in my case it's to ignore sample code I stick in DevOps projects).
• Bonus: I added Job steps to correctly determine which branch to diff files with (in the case of having multiple release branches).
• Bonus: Lints only changed files on a PR, but lints all files on merge to main (or any release) branch.

1. Fork this repository for you to customize your linters in a single location for your org/projects.
2. Add a new workflow to all your other repositories and paste in this YAML to call the central-repos reusable workflow.

Option 1: Use nektos/act to run an existing GitHub Action workflow on your local repository clone.

Option 2: Use Docker to run the Super-Linter image directly.
