Re: Cabals' Paths_pkg and GHCi
Vyacheslav Akhmechet wrote: Hi, I took advantage of Cabal's data-files feature to allow me to portably store and access data files. Cabal generated a Paths_pkg module that I imported. From Cabal's point of view everything works: I can configure, build, install, and run. However, I can no longer use GHCi with the file that imports Paths_pkg - GHCi simply can't find the module. Is there a good way to fix this issue? The Paths_foo.hs file is generated in a separate directory, something like dist/autogen/ (I can't remember exactly, you should be able to find it). To get GHCi to find it, you'll need to pass an appropriate -i dir flag.

Actually I did write the code for such a thing a while back, but never finished it off. There's a design choice; do you want - GHCi to understand .cabal files, or - Cabal to launch GHCi I concluded that the latter would be better, because then any hooks in your Setup.hs file still work, for example. I think this would make a nice bitesized task for someone who wants to do some Cabal hacking.
