This scanner is really complex, since Ruby is a complex language!

It tries to highlight 100% of all common code, and 90% of strange codes.

It is optimized for HTML highlighting, and is not very useful for parsing or pretty printing.

For now, I think it’s better than the scanners in VIM or Syntax, or any highlighter I was able to find, except Caleb’s RubyLexer.

I hope it’s also better than the rdoc/irb lexer.
