Hello,

Good idea! I made a little web-page with examples and screenshots. Have a look:

https://github.com/yav/graphmod/wiki

Indeed, mutually-recursive modules are not a problem. There is an example of some mutually-recursive modules in the screen-shot from GHC's type-checker.

By the way, I also added some support for modules that contains CPP, and improved the layout of the graphs a bit, so the current version is 1.2.5.

That helped a lot. I packaged graphmod (and xdot) on NixOS. It graphviz kept segfaulting[2] on the file produced for Yi repository but in the end it worked after I added ‘-p’ to graphmod. Also --no-cluster view at [3]. Is there any plan for graphmod to do rendering itself, such as to PNG? I also wonder if there's any way to highlight cyclic paths, useful when trying to get rid of boot files.

Hello,

I am pleased to announce a new version of `graphmod`---a program that helps you visualize the import dependencies between the modules in your Haskell programs.

The new feature in version 1.2.4 is support for pruning the dependency graph, which is enabled with the flag -p or --prune-edges. When this option is selected, `graphmod` will ignore imports to modules that are already imported by some of the dependencies of the module.

For example, consider the following modules:

module A where { import B; import C } module B where { import C } module C where { }

When generated with `--prune-edges`, the resulting graph will be:

A -> B -> C

Note that there is no edge from `A` to `C`, because `C` is already imported by `B`.

Happy hacking, -Iavor

Hi,

It'd be great if the project page showed an example use and the generated graph.

Does it work with possibly mutually-importing boot files?
