Djot PHP: A Modern Markup Parser – DerEuroMark

Djot is a lightweight markup language created by the author of CommonMark and Pandoc, designed to fix Markdown's ambiguities with a more consistent and predictable syntax. The php-collective/djot PHP library brings full Djot support to PHP 8.2+ with 100% compatibility with the official test suite. Key features include rich text formatting (highlight, insert, delete, super/subscript), smart typography, task lists, divs with classes, span attributes, and an AST-based architecture. The library offers an extension system with built-in extensions for autolinks, TOC, external links, and heading permalinks, plus a Profile system for restricting markup features per context (e.g., comment sections vs. blog posts). Performance benchmarks show djot-php processes ~2.6 MB/s, faster than league/commonmark but slower than simpler regex-based parsers like Parsedown. A WordPress plugin and IntelliJ IDE plugin are also available. Migration tools support importing from Markdown, HTML, and BBCode.
