Can't you use cabal as a library to do this? I had a crack at figuring out a ghci command line in TBC (testing by convention): https://github.com/peteg/TBC while waiting for this cabal feature to be implemented: http://hackage.haskell.org/trac/hackage/ticket/382 Apparently there's a GSoC project that will nail this. You can fire up TBC with the verbose flag and it will give you a very long ghc invocation line that is strongly similar to what cabal uses to compile your project. It doubtlessly is incomplete, and probably bit rotten. I will try to make it work with the latest Haskell Platform release in the coming weeks. I welcome patches, but you're better off fixing cabal itself. cheers peter -- http://peteg.org/ _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
