Midi Lib

Copperbox revision 72.

Updated the file MidiWrite.hs so that it uses the changes to the the Midi datatypes (these changes should have gone in with yesterday's check-in - revision 71).

Added a demo - DemoTrack.hs - that outputs a scale using MidiWrite.

Midi Lib

Copperbox revision 71.

Replaced the Midi file library with a new version. The new version has error handling - undoubtedly a big plus. It is still a quite rough at the edges as I'm working out how much to use the combinators from Control.Applicative and how much to use my own combinators.

C Front End

(aka Frown: c2hs parser)

Copperbox revision 70.

The declaration printer (CDeclr) wasn't printing qualifiers for array declarations, it now does. I've also removed the previous pretty-print combinator libraries as they are no longer used.

Frown: c2hs parser

Copperbox revision 69.

Phew! The new pretty printer is now working properly, so I've update the C printer to use it. There is still quite a bit of work to do on the both parts, but I think I am generally happy with both of them.

Frown: c2hs parser

Copperbox revision 68.

I have added another `empty biased` pretty printer - this one is based on Control.Applicative and is very much a work-in-progress.

Last weekend, I attempted to add layout styles to the C pretty printer using the monadic pretty printer. However the monadic interface wasn't as usable as I had imagined; the new applicative version will hopefully overcome some of its predecessors shortcomings.

Frown: c2hs parser

Copperbox revision 67.

Added a reader monad interface to the pretty printer as per Language.Haskell.Pretty.

This will allow the pretty printer to have different indent and bracing styles.

Frown: c2hs parser

Copperbox revision 66.

Cosmetic updates to the pretty printers again. But I wanted to get a working version committed now as the next step is to try a reader monad version that can handle indent preferences, etc.
