mdast Comment Marker Parser

mdast-comment-marker is a utility for parsing structured markers from comments within an mdast (Markdown Abstract Syntax Tree) document. It's currently at version 3.0.0 and follows a release cadence tied to major ecosystem updates like Node.js versions and mdast/MDX specifications. This package differentiates itself by providing a robust way to extract 'processing instructions' or metadata embedded in HTML or MDX comments, such as `<!-- lint disable -->` or `/* zone foo */`. It handles various parameter types including booleans, numbers, and strings, making it suitable for tools like remark-lint or mdast-zone, which utilize these markers for configuration or content manipulation. It is ESM-only and requires Node.js 16 or later.
