wumpus-drawing

High-level drawing objects built on Wumpus-Basic.

** WARNING ** - this package is sub-alpha. Although many of the drawing objects have been improved since the code was split from Wumpus-Basic, the code is still prototypical. Essentially this package is a technology preview and not yet a re-usable library.

NOTE - many of the demos use font metrics. Font metrics for the "Core 14" PostScript fonts are distributed as *.afm files with GhostScript in the fonts directory. Wumpus expects the GhostScript font metrics to be AFM version 2.0 files (this matches GhostScript 8.63). Alternatively, metrics for the Core 14 fonts are available from Adode (AFM version 4.1), see the links below. To run the demos properly you will need one of these sets of metrics.

Also note that Wumpus uses fallback metrics (derived from the monospaced Courier font) when font loading fails, rather than throwing a terminal error. Applications should ideally check the font loading log to ensure that fonts have loaded correctly (the demos print this log to standard out).

Changelog:

v0.8.0 to v0.9.0:

• Updated to work with wumpus-basic-0.24.0.

• Removed monoid mappend alias (<>) as it is now defined by Data.Monoid.

v0.7.0 to v0.8.0:

• Changed API to make Connectors.

• Added InclineTrails to Drawing.Basis.

• Reworked Extras.Loop.

v0.6.0 to v0.7.0:

• Changed paths - RelPath has been removed and there are now only absolute paths. PathBuilder builds absolute paths. Pen updating in PathBuilder now works like a State monad rather than local in a Reader monad.

• Changed argument order of the run functions to monadLib style (params * monadic action) rather than MTL style (monadic action * params).

• Added Symbols to Drawing.Basis.

• Added a tube box connector.

v0.5.0 to v0.6.0:

• Removed LocTrace and RefTrace from Wumpus.Drawing.Basis, they are superseded by LocDrawing in Wumpus-Basic.

• Remaned path building operations in RelPathBuilder.
