{code-cell}directives - Math directive highlighting with LaTeX syntax highlighting for
{math}directives - Automatic filetype detection for MyST markdown files based on content patterns
- Tree-sitter integration for robust parsing
- Comprehensive testing with 170+ tests
The plugin supports a wide range of languages in code-cell directives, including Python, Julia, R, JavaScript, and more.
