I am currently involved with a Haskell project to create a toolset for a formal language. The toolset contains a parser, a typechecker and s range of other features.

The Haskell code currently consists of about 20 modules. I am new in the project, and my impression is that a lot of code does not reside in the proper module. I would like to be able to get a good feeling in how the modules are structured, and how they are consumed by other modules. This would enable me to clean up a little bit.

I use eclipsefp. Do you know of any way to get insight of the structure of modules? is any tooling available? Any suggestions would help a lot! Thanx for reading.

There's been a few projects at Galois for this kind of high level structural analysis. We're trying to polish them up into a release. For now, there's one tool you can get started with: graphmod. This tool was written by Andy Gill (the dotgen part) and Iavor Diatchki (the graphmod part), and you can use it like so: $ git clone http://code.haskell.org/graphmod.git $ cd graphmod -- build dotgen $ cd dotgen .. edit the .cabal file to add the line: Build-type: Simple after the Exposed-modules line $ cabal install -- build graphmod $ cd .. $ cabal install ... Installing: /home/dons/.cabal/bin Now you have 'graphmod' a tool for drawing the module structure. So go find a project, and analyze it: $ cd ~/xmonad -- generate module graph $ graphmod XMonad XMonad.hs Main.hs > /tmp/xmonad.dot -- generate svg of graph $ dot -Tsvg /tmp/xmonad.dot > xmonad.svg Which gives this result: http://galois.com/~dons/images/xmonad.svg Enjoy! -- Don
