Hi Andreas,

Looks good. However,...

What I'd really want is to Regex-ify the syntax highlighter and
have them reconfigurable as user-supplied regex strings from
configuration files. This would simplify our life a lot. There'll
be only one syntax highlighter grammar and code that can accept
various lexer files. Our job then is just to churn out various
lexer files for different languages.

So, whatever you do with new lexer groupings, it must be
general enough for other languages too.

Would you like to work on the regexification?
