md4c: A fast, small, compliant Markdown parser implementation

MD4C is Markdown parser implementation in C, with the following features:

Compliance: Generally, MD4C aims to be compliant to the latest version of CommonMark specification.
Performance: MD4C is very fast.
Compactness: MD4C parser is implemented in one source file and one header file. There are no dependencies other than standard C library.
Portability: MD4C builds and works on Windows and POSIX-compliant OSes. (It should be simple to make it run also on most other platforms, at least as long as the platform provides C standard library, including a heap memory management.)
Permissive license: MD4C is available under the MIT license.

lila patches

I wote a few patches to tweak a bit how emphasis works. Each patch provides a new extension that can optionaly be enabled (at runtime, like existing extensions) :

ITALIC : To enable /italic/ support
BOLD : To enable *bold* support
BOX : To create some "box" blocks, for e.g. warnings, etc
HIGHLIGHT : To enable =highlight= support
INDENT : To enable indented block support

You can of course see all of them in use in qmdoc.

Latest release: 0.4.8.lila.2 (2023-07-24)
