The gomarkdown parser

https://github.com/gomarkdown/markdown

Notes made in late 2023; likely very out of date

GOOD

• It has no open pull requests - responsive owners
• Better documentation than goldmark.
• Clear access to the AST, as the API requires you to hold it in between parse and render.
• The AST has all the document contents.
• It supports block level attributes: {#id3 .myclass fontsize="tiny"}' on (at least) header blocks and code blocks

maybe problems

• It could support mermaid : https://github.com/gomarkdown/markdown/issues/284, but it's not clear if anyone did so.
• The number of contributors is unclear, since it's a fork of blackfriday.
• It has zero official releases at time of writing.
