BachMarkA markup language built for documentation.

CommonMark-inspired syntax with built-in extensions for technical writing — and first-class HTML & PDF output.

✍️

Familiar Syntax

If you know Markdown, you already know the basics. BachMark builds on CommonMark with carefully chosen extensions.

🧩

Built-in Extensions

Callouts, code groups, tabs, figures with captions, footnotes, citations, math, badges, keyboard keys, emoji shortcodes, colored text, and more — part of the language, not plugins.

📄

HTML & PDF Output

Both are first-class targets. PDF is generated directly from the AST — not by printing a webpage. Cross-references and figure numbering work across both.

Designed to Be Unambiguous

Precise parsing rules, a well-defined JSON AST, and conformance examples. Every feature is spec'd so renderers behave consistently.
