This repository is for the **GitHub** Action to run a **Super-Linter**.  
Developers on **GitHub** can call this Action to lint their code base with the following list of linters:


- **Ruby** (Rubocop)
- **Shell** (Shellcheck)
- **Ansible** (Ansible-lint)
- **YAML** (Yamllint)
- **Python3** (Pylint)
- **JSON** (JsonLint)
- **MarkDown** (Markdownlint)
- **Perl** (Perl)
- **XML** (LibXML)

## How to use

To use this **GitHub** Action you will need to complete the following:
- Copy **any** or **all** template rules files from `TEMPLATES/` into your repository in the location: `.github/linters/`
  - If your repository does not have rules files, they will fall back to defaults in this repositories `TEMPLATE` folder
- Add the **Github** Action: **Super-Linter** to your current **Github** Actions workflow
- Enjoy your more stable, and cleaner code base

### Example connecting GitHub Action Workflow

In your repository you should have a `workflows` folder with **GitHub** Action similar to below:

- `.github/workflows/linter.yml`

This file should have the following code:

```yml
