Assuming I get it included, is there any features in particular you'd want to see in there? Note that if I do have it produce visualisations, they'll be static images as part of an analysis report rather than being interactive.
I'd like the ability to show individual module dependencies, and then to collapse modules in one package to just the package, so I could "zoom out" and see how the packages relate to each other. By "package" here I mean the "A" in "A.B, A.C, etc."
It seems like it would be fairly simple to use Language.Haskell.Parse to turn a set of modules into a graph, and then something to massage that and give it to dot.
If you wanted to go down that route, try using 'ghc --make -v2' and translate that dependency graph to dot.
Yep, this is a pretty easy route and there is already a tool for doing the translation: ocamldot. Don't be fooled by the name, it works on Makefile's dependency information and in particular works well with the output from ghc. Back in the days (like six years ago) I used it on ghc itself. I also extended it so that different directories were grouped together inside a box to get a better feel for the intended structure of the program. ocamldot can be found here: http://www.research.att.com/~trevor/ocamldot/ I should add that I didn't find the information the least bit helpful so my general recommendation is to try to find some other method to help understanding code. All the best, Josef
