wumpus-core: Pure Haskell PostScript and SVG generation.
Wumpus is a low-level library for generating static 2D vector
pictures, its salient feature is portability due to no FFI
dependencies. It can generate PostScript (EPS) files and SVG
files. The generated PostScript code is plain  and reasonably
efficient as the use of stack operations, i.e
grestore, is minimized.
Wumpus makes pictures from paths and text labels. Paths themselves are made from points. The usual affine transformations (rotations, scaling, translations) can be applied to Pictures. Unlike PostScript there is no notion of a current point, Wumpus builds pictures in a coordinate-free style.
For actually drawing pictures, diagrams, etc. Wumpus is very
low-level. There is a supplemantary package
available that helps create certain types of diagram, but it is
experimental - functionality is added and dropped between
releases, it has no stable API.
Some of the design decisions made for
wumpus-core are not
sophisticated (e.g. how attributes like colour are handled,
and how the bounding boxes of text labels are calculated), so
Wumpus might be limited compared to other systems. However,
the design permits a fairly simple implementation, which is a
\[1\] Because the output is simple, straight-line PostScript code, it is possible to use GraphicsMagick or a similar tool to convert EPS files generated by Wumpus to many other formats (bitmaps).
34.0 to 0.35.0:
Bug fix - PostScript output - when more than one stroke property changed the changes were concatenated without a separator. This generated invalid PostScript. Now fixed.
Documentation updates to the guide and the Haddock docs.
