Hello all I'm the author of Wumpus (vector graphics) and Neume (music score setting).
Wumpus is on Hackage. Wumpus-Core is the stable part - it is a library for generating PostScript and SVG from a fairly simple graphics model that's somewhat like PostScript but is essentially stateless. Wumpus has some other libraries that are a bit more problematic. As anyone who has dabbled in vector graphics soon finds out, the hiatus between the simple drawings (Lindemayer systems, Sieperski triangles, ...) and complicated but actually useful graphics (charts, block diagrams, petri nets...) is huge. The other Wumpus libraries (Wumpus-Basic, Wumpus-Drawing, Wumpus-Tree) are work towards producing useful graphics, unfortunately they are a long way from being generally useful: functionality and API's regularly change or disappear. Ideally I wouldn't have put the higher-level packages on Hackage as I wouldn't recommend anyone use them in their present state, but when I uploaded them I felt they were a lot nearer readiness than they turned out to be. Some pictures are on Flickr: http://www.flickr.com/photos/44929957@N03/ Neume generates LilyPond and ABC scores from Haskell, it rather resembles Wumpus-Core in that it manages the low-level functionality pretty well but for practical use there's another big hiatus between the low-level functionality and a higher-level model that would be pleasant and concise to program with. I have tried to tie Neume to Haskore, but Haskore has numeric (rather than symbolic) note lengths and arbitrary nesting of "systems" via the par combinator. Both of these make Haskore a very difficult candidate for a (printed) score language. Neume isn't on Hackage as although it is competent at what it does, it's a long distance from being a "Text.PrettyPrint for LilyPond" and I think people might expect it to be a "pretty print for LilyPond" if they stumbled across it in the wild. I hope to pick up work on Neume this summer after I've pushed Wumpus further along. Again there are some examples on Flickr.
