Hello All, I'm not sure if this either a bug in how ghc does path/module lookup or it simply is invalid haskell:
consider modules A, A.B and A.B.C where A imports A.B, and A.B imports A.B.C with the following file system layout
A.hs A/B.hs A/B/C.hs
minimal file examples: module A where import A.B testA = "will it really really work? ------------ module A.B where import A.B.C testB = "will it work ----------------- module A.B.C where testC = "will this work?" ---------- if i run ghci A.hs everything's fine but if in directory B i rune ghci B.hs, i get A/B.hs:2:8: Could not find module `A.B.C': Use -v to see a list of the files searched for.
----------- it seems to me that if the default search path for ghc(i) includes the current directory (which according to docs it does), this shouldn't be happening. (or is there some why this is good Behavior?)
I think ghci is just not smart enough to know that it should change to the parent directory and run it from there. As such, it's trying to find "A.B.C" from the context of the current directory, and the file is not in A/A/B/C.hs so it can't find it. So it's just a limitation of ghci (I think). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
