What I can say is that the new system is much simpler than the current one. It is also based on well-documented ideas: http://blog.sigfpe.com/2009/01/fast-incremental-regular-expression.html http://www.cse.chalmers.se/~bernardy/PP.pdf (Plus upcoming Master theses) I also would like a new highlighting scheme to serve as example and > documentation.

As I recall it, even with the current system, making a new highlighter using regular expressions is a matter of hours one an Alex file with regular expressions has been produced. (Just repeat the pattern of existing highlighters). I am not sure why you bring Pygments in the picture: are you really suggesting to call Python from Yi to get highlighting info? A drawback of the current system is that it is quite hard to go beyond regexps: making a parser suitable for detection of syntax (including paretheses) is quite of a black art. This should be solved with the new system: is will accept any grammar in BNF format).
