Re: [Haskell-cafe] How to find unused exported symbols?

I wonder if I should use the GHC API to do this. I notice there is a module called BinIface that contains a reader for interface files. The trouble is you have to figure out how to initialize a program that uses the module, and that seems to be difficult. I couldn't find anything relevant on the Wiki.

I would like to find symbols exported from each module in a program that are not used outside the module.  I'm worried my program is accumulating cruft.  I'm looking for suggestions on how to find unused exported symbols.  Do I have to analyse .hi files?  Thanks in advance.

-Wall will tell you which entities in are module are top-level but not exported; my SourceGraph program (available from Hackage) will tell you which entities in the entire project are top-level but not exported.  Note that at the moment the output is rather ugly....
