[Haskell-cafe] ANNOUNCE: SourceGraph-0.6.0.2

I've just uploaded a new version that works with haskell-src-exts-1.6.0 (all it needed was to increase the upper bound in the cabal file! \o/). On another note, anyone know why Niklas Broberg hasn't been making any release statements recently to say what the changes are, etc. for haskell-src-exts? Ivan Lazar Miljenovic writes:

I realised soon after I sent the announcement email that there was a bug in one of the new "subtle" features that I didn't list, namely the background shading of directories in import visualisation. As such, SourceGraph 0.6.0.1 contains this fix.

There were also two other features in 0.6.0.0 that I forgot to mention:

* SourceGraph will (well, should; I haven't managed to come across a situation where it occurs anyway) no longer throw a fit if Graphviz throws an error when visualising a graph; instead it will just put an error message into the generated report.

* The generated Dot code is also saved in the SourceGraph/graphs/ subdirectory, so you can tweak the call graphs of your programs.

I'm pleased to announce the latest releases of SourceGraph [1] and Graphalyze [2].

[1]: http://hackage.haskell.org/package/SourceGraph [2]: http://hackage.haskell.org/package/Graphalyze

SourceGraph is a program that performs static code analysis on Haskell projects on the by applying graph theoretic techniques to the project's call graph. Graphalyze is a library for analysing discrete data using graph theory, and as such performs the heavy lifting for SourceGraph.

Sample analysis reports generated by SourceGraph are available at http://code.haskell.org/~ivanm/Sample_SourceGraph/SampleReports.html . I will also be demoing SourceGraph at PEPM [3] in Madrid on 19 January.

Changes since the previous version include:

* Now supports "implicitly exported" entities (as requested by Curt Sampson). This includes instantiated class methods from other modules and functions, etc. that start with an underscore (see http://www.haskell.org/ghc/docs/latest/html/users_guide/options-sanity.html for more information).

* All inaccessible entities are now reported, not just those that were root nodes in the call graph.

* Edges are now colour-coded based upon whether they are part of a clique, cycle or a chain.

* Level-based analyses: visualise how deep an entity is from those exported entities.

* A re-done TODO that lists in detail what is planned for SourceGraph.

* Lots of under-the-hood changes that don't sound as interesting as the above :-(
