longDescription = ''
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. Currently, we are fully compliant to
CommonMark 0.29.
- Extensions: MD4C supports some commonly requested and accepted
extensions. See below.
- 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.
- Embedding: MD4C parser is easy to reuse in other projects, its API is
very straightforward: There is actually just one function, md_parse().
- Push model: MD4C parses the complete document and calls few callback
functions provided by the application to inform it about a start/end of
every block, a start/end of every span, and with any textual contents.
- 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.)
- Encoding: MD4C by default expects UTF-8 encoding of the input
document. But it can be compiled to recognize ASCII-only control
characters (i.e. to disable all Unicode-specific code), or (on Windows)
to expect UTF-16 (i.e. what is on Windows commonly called just
"Unicode"). See more details below.
- Permissive license: MD4C is available under the MIT license.
