I'm pleased to announce the latest version of my Haskell bindings to the Graphviz [1] suite of tools for visualising graphs. As usual, it is available from Hackage [2]. [1] http://graphviz.org/ [2] http://hackage.haskell.org/package/graphviz Changes in this release include: * Updated and extended functions to interact with the Graphviz tools. This now includes: - a better listing of available output types; - distinguishing file outputs from canvas outputs; - ability to automatically add the correct file extension to file outputs - Return any errors if calling Graphviz failed rather than just printing them to stderr * Improved Color support: - fixed ColorScheme values - explicitly named X11 colors - conversion to/from values from the colour library * Removed OrientationGraph; problems with distinguishing it when parsing from node-based Orientation values; its functionality is duplicated by Rotate. * By default, the generated Dot code is now no longer indented; you can now use the prettyPrint functions in Data.GraphViz to produce readable Dot code. * Added a testsuite; this is buildable by building with --flags=test. Numerous printing and parsing bugs were picked up with this. Plans for the next release: * Determine how to deal with encodings, since Graphviz uses UTF-8 by default; the hSetEncoding function in GHC-6.12 would be ideal, but backwards-incompatible. * Add a generic version of the types in Data.GraphViz.Types that would let people have more fine-grained control over the layout of their graphs by removing the ordering restriction used. Note that this will _not_ be the default, just an option for those that want it. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
