Copperbox revision 1154.

Work on a new beam grouping and bar splitting algorithm.

This one seems a lot more promising than previous attempts. What I'm doing is segmenting into metrical units that match each division of a meter pattern - say if I'm in 4-4 time with two beam groups each of a half note. I split the input stream into chunks of a half note in duration (possibly with some borrow). To turn the segmented stream into bars I take two chunks at a time and amalgamate them into a bar (beam grouping inside the chunk when necessary).

This is much simpler than what I was trying before, where I had split the input into single notes and beam groups and had to count them all again to form a bar.

I've easily accounted for a start anacrusis with the new algorithm and in my head it works for n-ary tuplets, though I have to work the details out - I'm still not sure what form n-ary tuplets should have in the intermediate syntax tree.

Work on summing the duration of PletTrees. It seems wrong at the moment but that might be my test instead, so I want the code check pointed.

Back to work on Neume...

This time I'm working with input data type that can handle n-ary tuplets from the beginning. Last time bracketing quickly became too complicated, before I even thought about triplets and duplets, so I've decided to put them in from the start. Unfortunately this means I'll have to work with trees rather than simple linear lists - tuplets can be nested so this mandates trees.

Copperbox revision 1151.

I've added the row formatting module from Hurdle to JoinPrint (where it belongs) and a couple of missing formatters (list, tupled, and semiBraces).

Hurdle-0.4.0

Copperbox revision 1150.

I've made a new release of Hurdle - no new functionality, but it does use the latest Kangaroo.

Hurdle

Copperbox revision 1149.

I've worked out a new formatter for tables via the TypeCase pattern. When integrated it should improve the TextDump module quite a bit, currently its quite horrible.

kangaroo-0.4.0

Copperbox revisions 1147 & 1148.

A new release of kangaroo with the JoinPrint improvements.

Revision 1147 has the new tar archive with the latest cabal file in the archive. Unfortunately I missed committing the latest cabal file with 1147, so it is committed at 1148.
