What it is and what it does
mdformat-myst is a plugin for the mdformat Markdown formatter that shifts its target specification from CommonMark to MyST, a richer Markdown variant used in the Jupyter and Sphinx ecosystems. It allows mdformat to understand and consistently format MyST-specific syntax such as directives, roles, inline and block math, comments, block breaks, targets, front matter, and footnotes—features that standard CommonMark formatters would not recognize.
The plugin works by extending mdformat's parsing and formatting rules. You install it alongside mdformat and use mdformat normally; the plugin integrates into the tool's pipeline. It depends on mdformat itself, mdit-py-plugins for parsing, and several other mdformat plugins (front-matters, footnote, gfm) to handle the full range of MyST extensions. This makes it useful for projects that author documentation or content in MyST and need consistent formatting without manual intervention.
Use it for
- Format Jupyter Book or Sphinx documentation written in MyST Markdown while preserving directives and roles.
- Enforce consistent style on MyST files that use math blocks, tables, and custom directives across a project.
- Integrate MyST formatting into CI/CD pipelines to lint and auto-format documentation sources.
- Convert and format existing Markdown to MyST-compatible syntax with proper handling of extended features.
- Maintain code style consistency in technical documentation that mixes CommonMark and MyST syntax.
