I'd like to announce version 2009.5.1[1] of the graphviz[2] library, less than a week since Matthew Sackman passed maintainership onto me[3]. The graphviz library provides a Haskell interface to the GraphViz[4] program. [1] http://hackage.haskell.org/packages/archive/graphviz/2009.5.1/graphviz-2009.... [2] http://hackage.haskell.org/cgi-bin/hackage-scripts/package/graphviz [3] http://www.mail-archive.com/haskell@haskell.org/msg21994.html [4] http://graphviz.org Major changes with this release are: * Supports polyparse >= 1.1 (the previous version didn't work with 1.3). * Requires base == 4.* (i.e. GHC 6.10.*) due to the new exception handling. * Includes functions from my Graphalyze [5] library for actually running the various GraphViz commands, etc. * Slight API breakages: - dirCommand, undirCommand and commandFor no longer return String, but GraphvizCommand - Data.GraphViz.ParserCombinators is no longer exported by the Cabal file, since I see no need for anyone to require acccess to this. If this is a problem for you, please let me know and I'll re-export it. * A lot more Haddock documentation. * A darcs repository is now available [6]. Patches are welcome! [5] http://hackage.haskell.org/cgi-bin/hackage-scripts/package/Graphalyze [6] http://code.haskell.org/graphviz Plans for the future: * Add support for Data.Graph-style graphs (maybe even making it generic such that custom graph types can be used). * Allow the user to choose whether the graph is directed or undirected. * Include all attributes offered by the Dot language. * Remove (or at least minimise) usage of extensions to increase portability. Oh, and to pre-empt Don, this is already available in the Gentoo-Haskell overlay ;-) -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
