markcraft 1.0.2

A fast, extensible Markdown parser in pure Python.

markcraft

Your next Markdown parser in Python: pure Python, CommonMark-oriented, and easy to extend.

Why You Will Like It

• Pure Python, no C extension burden: simpler deployment across environments.
• CommonMark-oriented behavior: predictable parsing with stable token precedence.
• Extensible architecture: add custom block/span tokens and custom renderers.
• More than HTML output: ships with HTML, LaTeX, AST, and Markdown renderers.
• Built for maintainability: parser and renderer responsibilities stay cleanly separated.

Installation

Install from PyPI:

pip install markcraft

Local development setup (uv + Python 3.13):

git clone https://github.com/niu2x/markcraft.git
cd markcraft
uv sync

30-Second Quick Start

1) Render to HTML by default

import markcraft

with open("example.md", "r", encoding="utf-8") as fin:
    html = markcraft.render(fin)

2) Use a specific renderer (for example, LaTeX)

import markcraft
from markcraft.renderers import LaTeXRenderer

with open("example.md", "r", encoding="utf-8") as fin:
    latex = markcraft.render(fin, LaTeXRenderer)

3) Parse explicitly when you need a Document tree

import markcraft
from markcraft.renderers import MarkdownRenderer

doc = markcraft.parse("a\n\n[b]: /uri\n")

with MarkdownRenderer() as renderer:
    renderer_specific_doc = markcraft.parse("a\n\n[b]: /uri\n", renderer)
    markdown = renderer.render(renderer_specific_doc)

Why call markcraft.parse(...) twice here?

• doc = markcraft.parse(...) uses the default parser path and returns a generic Document tree.
• markcraft.parse(..., renderer) parses with renderer context, so renderer-specific token rules are included when needed.
• Use the first form for renderer-agnostic analysis; use the second form when your renderer adds or depends on extra syntax.
