markdown-katex is an extension for Python Markdown that adds KaTeX support. It processes LaTeX math formulas within Markdown text and converts them into HTML that can be rendered by KaTeX, often including bundled KaTeX binaries for server-side rendering, thus reducing reliance on client-side JavaScript. It primarily supports GitLab-style math delimiters. The current version is 202406.1035, with a release cadence that often aligns with KaTeX binary updates and bug fixes.

Initialize the `Markdown` parser with `KatexExtension` and convert Markdown text containing GitLab-style math formulas. The output HTML will contain the necessary KaTeX-generated markup. Note that for visual rendering, the KaTeX CSS must be linked in the final HTML document.
Ensure your Markdown content uses the GitLab-style delimiters. If you require other delimiters, you might need a different Python Markdown extension or a custom preprocessor.
Where possible, escape problematic Markdown characters within your LaTeX (e.g., `\_` instead of `_`). Consider adding additional Markdown extensions that handle math syntax more robustly (e.g., `pymdownx.arithmatex` in 'generic' mode, though `markdown-katex` provides its own parsing). For Python strings, use raw strings (e.g., `r'\frac{1}{2}'`) to avoid Python's backslash escaping interfering with LaTeX.Always include the KaTeX CSS in your HTML `<head>` section. Ensure your HTML files have the `<!DOCTYPE html>` declaration at the very top.
To ensure consistent rendering, manage your `katex-cli` installation (e.g., via `npm`) carefully or ensure it matches the bundled version. If specific behavior is required, you may need to control your `PATH` environment variable or explicitly manage the `katex-cli` executable used.
