This Go package provides a CommonMark parser, a specific dialect of Markdown. It allows you to parse, analyze, and render CommonMark/Markdown documents with an abstract syntax tree API.

This implementation conforms to Version 0.30 of the CommonMark Specification.

A few other Markdown/CommonMark packages exist for Go. This package prioritizes (in order):

1. Ability to connect the parse tree to CommonMark input losslessly in order to enable creation of tools that reformat or manipulate CommonMark documents.
2. Adherence to CommonMark specification.
3. Comprehensibility of implementation.
4. Performance.
