wumpus-basic
Copperbox revisions 1918 and 1919.
I've split the Wumpus-Basic hierarchy into two layers Basic and Drawing. Basic contains the core graphic types, the font loader code, and the utilities (parser combinators etc.). Drawing contains the "derived" drawing objects Dots, Arrows, LRText etc. Basic had simply become to big to work with. Note that there will be further changes as I balance things out in Basic.Graphic.

wumpus-core
Copperbox revision 1917.
I've improved the handling of null paths (paths with an empty list of path segments) and empty text labels - labels with empty string for text. Neither generate PostScript and SVG output any more. Previously they generated output that wasn't actually printed (i.e. moveto instructions but no lineto instructions), the improvement saves code size. There is also a new constructor in the Picture API to create empty paths.

wumpus-clave
Copperbox revision 1916.
More pieces are working for djembe pattern drawing, though the code is still first draft quality. I can now draw a pattern with n-plets, or swing.

Copperbox revision 1915.
More work on djembe patterns. I'm starting to get a feel for what needs to be done, though it isn't apparent in the code yet.

wumpus-clave
Copperbox revision 1914.
Exploratory work on a data type representation of djembe patterns. Its made complicated because I want to have two interpretations of djembe patterns - one to draw with Wumpus and one to output MIDI, but I don't want to encode every possible notehead in the data types (this wouldn't be extensible). To get extensibility, I'm currently trying to use a typecase / tagless style.
