A [Woodpecker CI](https://woodpecker-ci.org) plugin for [markdownlint-cli](https://github.com/igorshubovych/markdownlint-cli) to lint markdown files.  
Also usable with Gitlab, Github or locally, see examples for usage.

## Features

- preconfigure markdownlint-cli parameters
- searches for markdown files recursive
- runnable with local docker daemon

  markdownlint:
    image: kokuwaio/markdownlint
    settings:
      dot: true
      enable: [MD013, MD041]
    when:
      event: pull_request
      path: [.markdownlint.yaml, "**/*.md"]]
```

Gitlab:

```yaml
markdownlint:
  stage: lint
  image: kokuwaio/markdownlint
  variables:
    PLUGIN_DOT: true

  rules:
    - if: $CI_PIPELINE_SOURCE == "merge_request_event"
      changes: [.markdownlint.yaml, "**/*.md"]
```
