md2typst 0.3.0

Markdown to Typst converter with multiple parser support

md2typst

A robust Markdown to Typst converter in Python with support for multiple Markdown parsers.

Features

• Multiple parser backends: Choose from markdown-it-py, mistune, or marko at runtime
• GFM support: Tables, strikethrough, and other GitHub Flavored Markdown extensions
• Configurable: TOML configuration files and CLI options
• Extensible: Plugin support for parser-specific extensions
• Well-tested: Comprehensive test suite with TCK validation against CommonMark

Installation

# Using pip
pip install md2typst

# Using uv
uv add md2typst

Quick Start

Command Line

# Convert a file
md2typst input.md -o output.typ

# Convert from stdin
echo "# Hello **World**" | md2typst

# Use a specific parser
md2typst --parser mistune input.md

# Convert directly to PDF (requires typst CLI)
md2pdf input.md
md2pdf input.md -o custom-output.pdf

# List available parsers
md2typst --list-parsers

Python API

from md2typst import convert

# Simple conversion
typst = convert("# Hello **World**")
print(typst)
# Output: = Hello *World*

# With specific parser
typst = convert("~~deleted~~", parser="mistune")
print(typst)
# Output: #strike[deleted]

# With configuration
from md2typst import convert_with_config
from md2typst.config import Config

config = Config(parser="marko", plugins=["gfm"])
typst = convert_with_config("| A | B |\n|---|---|\n| 1 | 2 |", config)

Supported Parsers

Parser	CLI Name	Description
markdown-it-py	markdown-it	Default. CommonMark compliant, extensible
mistune	mistune	Fast, pure Python
marko	marko	CommonMark compliant, extensible

All parsers have GFM extensions (tables, strikethrough) enabled by default.

Markdown to Typst Mapping

Markdown	Typst
# Heading	= Heading
## Heading 2	== Heading 2
*italic*	_italic_
**bold**	*bold*
~~strike~~	#strike[strike]
`code`	`code`
[text](url)	#link("url")[text]
	#image("url", alt: "alt")
> quote	#block(...)[quote]
---	#line(length: 100%)
GFM tables	#table(...)

Configuration

Configuration is loaded from multiple sources (highest priority first):

1. CLI arguments (--parser, --plugin)
2. Explicit config file (--config path/to/config.toml)
3. .md2typst.toml in the current or parent directories
4. [tool.md2typst] section in pyproject.toml

Example Configuration

.md2typst.toml:

parser = "mistune"
plugins = ["strikethrough", "table"]

[parser_options]
html = true

pyproject.toml:

[tool.md2typst]
parser = "markdown-it"
plugins = ["gfm"]

Front Matter

Markdown files can include YAML front matter for metadata, stylesheets, and raw Typst preamble:

---
title: My Document
author: Jane Doe
stylesheet: my-style
preamble: |
  #set text(lang: "fr", hyphenate: true)
  #set par(justify: true)
  #show heading.where(level: 1): it => { it; v(0.5em) }
---

# Hello World

This generates:

#let doc-title = "My Document"
#let doc-author = "Jane Doe"

#import "my-style.typ": *

#set text(lang: "fr", hyphenate: true)
#set par(justify: true)
#show heading.where(level: 1): it => { it; v(0.5em) }

= Hello World

The output ordering is: variables, stylesheet imports, preamble, then content.

Architecture

Markdown Input → Parser → AST → Generator → Typst Output

The converter uses a parser-agnostic AST (Abstract Syntax Tree) that decouples parsing from code generation. This allows:

• Swapping parsers without changing the generator
• Consistent output regardless of parser choice
• Easy extension with new parsers
