# TARTRAZINE
|
|
|
|
Tartrazine is a library to syntax-highlight code. It is
|
|
a port of [Pygments](https://pygments.org/) to
|
|
[Crystal](https://crystal-lang.org/). 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](https://github.com/alecthomas/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.
