docdo 0.0.3

A CLI tool to render Markdown files to PDF via HTML templates and Playwright.

Docdo

CLI tool that converts Markdown files to PDF using Playwright and CSS themes.

Install

uv tool install docdo
playwright install chromium

Usage

docdo -i README.md                       # outputs README.pdf next to it
docdo -i docs/ -o out/                   # converts a whole folder
docdo -i README.md -t dracula            # use a built-in theme
docdo -i README.md -t ./my-style.css     # use a custom CSS file

Flag	Description
-i, --input	Markdown file or folder (required)
-o, --output	Output PDF file or folder (defaults to input location)
-t, --theme	Built-in theme name (default, dracula) or path to a .css file

Themes

Built-in themes live in src/docdo/themes/. To add your own, drop a .css file there or just pass any CSS file path with -t.

How it works

1. Parses Markdown with markdown-it-py (with pygments for syntax highlighting).
2. Wraps the HTML with the selected CSS theme.
3. Renders to PDF via Playwright (headless Chromium).
