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
• Math support: $...$ and $$...$$ rendered via mitex, enabled by default
• Mermaid diagrams: ```mermaid code blocks rendered via mmdr
• Auto-imports: Required Typst packages are automatically imported based on content
• Direct PDF output: md2pdf command converts Markdown to PDF in one step (requires typst CLI)
• Diagram blocks: ```diagram keeps ASCII-art diagrams from breaking across pages
• Configurable: User config, project config, YAML front matter, and CLI options with clear cascade
• 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 (writes input.typ by default)
md2typst input.md

# Explicit output path
md2typst input.md -o output.typ

# Output to stdout
md2typst input.md -o -

# Convert from stdin (outputs to stdout)
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]
$E=mc^2$	#mi("E=mc^2")
$$...\int...$$	#mitex(\...`)`
---	#line(length: 100%)
GFM tables	#table(...)
```mermaid	#mermaid("...")
```diagram	#block(breakable: false)[...]

Configuration

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

1. CLI arguments (--parser, --plugin, ...)
2. Front matter in the document
3. Explicit config file (--config path/to/config.toml)
4. md2typst.toml in the current or parent directories
5. [tool.md2typst] section in pyproject.toml
6. User config at ~/.config/md2typst/config.toml (platform-specific via platformdirs)
7. Built-in defaults

Styling with [style]

The [style] section customizes Typst's default output. Set your preferred font, language, and page layout once in your user config — applied to every document you convert.

~/.config/md2typst/config.toml:

[style]
# Font as single string or a fallback list
font = ["Libertinus Serif", "New Computer Modern", "Times New Roman"]
font_size = "11pt"
language = "en"
paper = "a4"
margin = "2.5cm"

# Raw Typst code appended after structured fields
preamble = """
#set par(justify: true, first-line-indent: 1em)
#show heading.where(level: 1): it => { it; v(0.5em) }
"""

This generates at the top of every converted document:

#set text(font: ("Libertinus Serif", "New Computer Modern", "Times New Roman"), size: 11pt, lang: "en")
#set page(paper: "a4", margin: 2.5cm)

#set par(justify: true, first-line-indent: 1em)
#show heading.where(level: 1): it => { it; v(0.5em) }

Example Configuration

md2typst.toml (project-level, overrides user config):

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

[parser_options]
html = true

[style]
language = "fr"

pyproject.toml:

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

Front Matter

Markdown files can include YAML front matter. Any field is exposed as a #let doc-<key> variable in Typst, except reserved keys with special handling:

• preamble — raw Typst code, concatenated with config style.preamble
• stylesheet / stylesheets — additional Typst modules to import
• font, font_size, language, paper, margin — override the corresponding [style] fields at document level

---
title: My Document
author: Jane Doe
language: fr          # overrides config style.language
font: EB Garamond     # overrides config style.font
stylesheet: my-style
preamble: |
  #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(font: "EB Garamond", lang: "fr")

#set par(justify: true)
#show heading.where(level: 1): it => { it; v(0.5em) }

= Hello World

The output ordering is: variables, stylesheet imports, package imports, #set directives from [style], preamble, then content.

Math

Dollar-sign math syntax is enabled by default (markdown-it and mistune parsers). The mitex package import is added automatically when math is detected.

Inline: $E = mc^2$

Display:
$$
\int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
$$

Mermaid Diagrams

Fenced code blocks with language mermaid are converted to native Typst diagrams using the mmdr package. The import is added automatically.

```mermaid
graph LR
    A[Start] --> B{Decision}
    B -->|Yes| C[OK]
    B -->|No| D[End]
```

Diagram Blocks

Use ```diagram for ASCII-art or box-drawing diagrams that must not break across pages:

```diagram
┌──────────┐       ┌──────────┐
│  Client  │──────▶│  Server  │
└──────────┘       └──────────┘
```

The content is wrapped in #block(breakable: false) in the Typst output.

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
