Montmark

A lightweight, fast, pure-Python Markdown parser

Small. Walkable. Full of shortcuts. Sketched on a Parisian hill.

Introduction

Montmark turns Markdown into HTML. It is more than 90% compliant with CommonMark specification.

WORK IN PROGRESS! This is ALPHA quality software. Do not use it in production!

Plan

• Continue ongoing updates progressively improving CommonMark compliance toward to near 100%
• Add support for GitHub tables
• Add streaming mode for low-memory processing of very large files
• Optimize

pip install montmark

As a standalone file

file montmark.py can be downloaded from GitHub or extracted from the PyPI package and used as a standalone script or module.

For standalone script:

Preliminary benchmark

Done with bench script and syntax.md sample from Mistletoe, on a 14th gen Intel Core i5 running Ubuntu 24.04

CommonMark compliance

Open-Source, not Open-Contribution yet

Montmark is MIT licensed but is currently closed to contributions.

Personal note: this is a pet projet of mine and my time is limited. First I need to focus on my roadmap (new features and refactoring) and then I will happily accept contributions when everything is a little more stabilised.
