tartrazine

Tartrazine is a library to syntax-highlight code. It is a port of Pygments to Crystal. Kind of.

It's not currently usable unless what you need is a way to turn your files into a pile of json describing its constituent tokens, because I have not implemented any formatters, yet, only the part that parses the code (the lexers).

A port of what? Why "kind of"?

Because I did not read the Pygments code. And this is actually based on Chroma ... although I did not read that code either.

Chroma has taken most of the Pygments lexers and turned them into XML descriptions. What I did was take those XML files from Chroma and a pile of test cases from Pygments, and I slapped them together until the tests passed and my code produced the same output as Chroma. Think of it as extreme TDD.

Currently the pass rate for tests in the supported languages is 96.8%, which is not bad for a couple days hacking.

This only covers the RegexLexers, which are the most common ones, but it means the supported languages are a subset of Chroma's, which is a subset of Pygments'.

Currently Tartrazine supports ... 241 languages.
