Hi Tom! [...]
Currently I'm using a monad that combines Parsec (with MIDI event
stream) and a Writer (that writes commands that should result in IO). It's done in a way that during running the monad, many parses can be done and failing parses roll back the parser state so that a new parse can be tried.
Care to share your code?
Yes, great! Have you worked with MIDI in Haskell? Perhaps parsing/recognizing it? I think it will take a few more days (hopefully not weeks) until I know what will be the foundation for my app. But then I will create a project online and send you a message. In case anybody has time to look at it, I just pasted my aforementioned monad on hpaste. I thought about it some more and came to the conclusion that for user-defined "triggers" (aka parsers), this approach is probably sub optimal... After Heinrich's suggestion, I worked through the slot machine example from reactive-banana. It's a great introduction to FRP for me. The declarative style is very appealing. I will try how it fits with my ideas. Some of my code (thaugh probably obsolete): http://hpaste.org/55795 Regards Tim
