About:
cmark-gfm is the official C reference implementation of GitHub Flavored Markdown (GFM). It provides a robust, fast, and secure parser for rendering Markdown into HTML or CommonMark. This tool ensures compatibility with GitHub's specific Markdown dialect, including features like tables, strikethrough, and task lists.

Key Features:

GitHub Flavored Markdown (GFM) compliance
Fast C-based parsing and rendering
Secure against malicious input (DoS prevention)
Extensible with custom renderers and plugins

Use Cases:

Building static site generators that need GFM support
Processing user-generated content in web applications
Command-line conversion of Markdown files to HTML

Alternatives:

commonmark – Strict CommonMark implementation; cmark-gfm adds specific GitHub extensions.
pandoc – Universal document converter; heavier weight than cmark-gfm for just Markdown parsing.
