I’d like to announce the introduction of CommonMarker, a Ruby implementation of the CommonMark spec. Unlike other Ruby implementations I found, this directly wraps the native C library, which means performance is nearly on-par with using raw C.
All of the C tests are passing. The Ruby implementation also offers the ability to build a custom renderer, though this is a bit slower than just using CMark natively. It’s kept simply as a Git submodule.
Pull requests are welcomed! I’ll try to keep in sync with CMark as often as possible.
