I just like to show and share my work. I hope here’s an appropriate place for this.
My project: https://github.com/Eonil/CommonMark
This is an Objective-C wrapper library around reference C implementation. Original C code is embedded into the project for simple and stable build. I tried to provide internal AST as much as possible.
If you find something wrong (bugs, license violations, bad manners or etc.), please let me know. Thanks.
