mdcheckr

mdcheckr is a testing tool to detect quality problems with your Markdown documentation. It is designed to act as a quality gate in your continuous integration pipeline.

• Syntax errors in code blocks - Syntax-check code blocks that identify their language. Currently works for:
  • bash (example)
  • PHP (example)
• Code blocks- Detection of un-closed code blocks (example)
• Broken links- Flag files that link to relative paths or URLs on the internet which can't be accessed (example, example).
• Broken images- Detect broken embeds, local and remote (example, example).

This tool is not intended to enforce a code style, and will not critique aspects of your Markdown code which do not affect the output.
