It's been a while in coming (I started work on this at the end of last year!) but I am pleased to announce the latest version of my graphviz library [1], which acts as a wrapper around the Graphviz [2] suite of graph visualisation utilities. [1] : http://projects.haskell.org/graphviz/ http://hackage.haskell.org/package/graphviz [2]: http://graphviz.org Major changes in this release (see the changelog [3] for a complete listing): * A large focus on increasing usability: - Examples for all Dot representations against an existing Dot graph - Cut-down, easier to use Attribute wrapper (all Attributes still available from Data.GraphViz.Attributes.Complete if you need any of the others). - graphElemsToDot helps visualise non-FGL graphs (if you can list all nodes and edges, you can visualise it!) * Two new Dot representations: - One that allows graph-based operations (based upon FGL) - Another based upon Andy Gill's dotgen [4] (with permission!) for easier embedding of relatively static graphs. * Pure Haskell implementations of `dot -Tcanon` and `tred`. * Now based upon Text rather than String, which improves performance for both printing and parsing and also enforces UTF-8 encoding. * Now easier to do custom I/O with Dot graphs. [3]: http://projects.haskell.org/graphviz/changelog.html [4]: http://hackage.haskell.org/package/dotgen Unfortunately, this release is largely backwards incompatible in some ways, but not too much. Specifically, it didn't take me long to migrate over Graphalyze [5] and SourceGraph [6], and most of that time was spent changing over to the new, nicer functions for creating Attributes. [5]: http://hackage.haskell.org/package/Graphalyze [6]: http://hackage.haskell.org/package/SourceGraph Please let me know if there are any other API improvements that you'd like to see to improve usage. I am planning a tutorial (half of the reason why this release took so long is that I kept thinking "this functionality would be useful for the tutorial!"; this includes the graph-based representation, the re-implementation of tred and canonicalisation, etc.), which should be out in the next month or so (I'm considering adding nicer syntax for record labels first). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
