Hello guys,
I have released ghc-mod version 4.1.0. In this version, ghc-modi provides "info" and "type" commands. This means that you can display types and information of expressions very quickly on Emacs.

Thanks to GHC's -fdefer-type-errors, "type" and "info" can work even if the file contains type errors. Yay! Of course, you can make use of GHC's hole. For more information, please read the "Types" subsection of the following page:

Enjoy!
Hi, I've been trying this thing out (including the Emacs integration) and it's working pretty well so far, but I've run into a limitation that's a bit frustrating. I have a multi-project setup sort of like the following: project/ A/ B/ (depends on A) C/ (depends on A) D/ (depends on B + C) (where D is an executable "example" project) To compile everything I've created a sandbox for the D project in project/D/ and run all my cabal commands from there. I've added A, B, and C via the "add-source" sandbox feature. If I edit a file in the D project, ghc-mod works beautifully, but if I edit anything in A, B, or C ghc-mod (understandably) cannot find the sandbox and complains about various packages (that A, B or C depend on) not being installed. It there some way to make this work? Would it help to actually create the sandbox in the project's main directory (A, B, C, D are subdirectories) and then add them all as source? Any help/guidance in getting this to work would be appreciated. Regards,
