Mmark: powerful markdown parser

The mmark-filter command allows you to rewrite the input markdown to new markdown.

The latest mmark versions gained a new renderer: -markdown that outputs markdown again. You can use this to autoformat the contents in your editor.

Mmark version 2.0.0 has been released! This means it is considered feature complete and stable. Any syntax that creates fishy HTML5 or the wrong RFC 7791/RFC 7749 output is considered a bug and should be fixed.

The easiest way to get started is to download one of the precompiled binaries. And familiarize yourself with markdown and it’s syntax and read our syntax document.

Xml2rfc should have a package for your operating system, otherwise it can be found on pypi. For version 3 output you’ll need at least 2.10.3, but newer is better.

Mmark is a powerful markdown processor written in Go, geared towards writing IETF documents. It is, however, also suited for writing complete books and other technical documentation, like the Learning Go book (mmark source, and I-D text output). It provides an advanced markdown dialect that processes file(s) to produce internet-drafts in XML RFC 7991 format. Mmark can produce xml2rfc (aforementioned RFC 7991), RFC 7749 (xml2rfc version 2), HTML5 output, markdown and manual pages.

This is version 2 of Mmark: based on a new markdown implementation and some (small) language changes as well. We think these language changes lead to a more consistent user experience and lead to less confusion. See changes from v1 if you’re coming from version 1. Biggest changes: Including files is now done relative to the file being parsed (i.e. the sane way). Block attributes apply to block elements only.
