Have you tried M-x haskell-process-unignore? On Sun, Apr 20, 2014 at 10:20 AM, Arnaud Bailly wrote:

If you're using several source directories then simply specify them in your .cabal with hs-source-dirs. So for example if you have a library in src/lib and a test-suite in src/test and your tests use your lib then you'd have something like this in your .cabal

library exposed-modules: Lib hs-source-dirs: src/lib

test-suite sometest type: exitcode-stdio-1.0 main-is: Test.hs hs-source-dirs: src/test src/lib

Hello,

I am struggling to get my emacs settings right for doing significant Haskell development, eg. something more involved than a bunch of source files in a single directory. The issue I am running in currently is that when trying to load files in the interpreter, most source paths are missing which means loading inevitably fails. This is especially annoying with tests: To get things working correctly I need to explicitly add in the console

...

:set -iwhere/my/src/are

Is there any configuration I should be aware of in my cabal files or .emacs file that would correctly set the source roots? Am I missing something?

Here is my .emacs configuration. Thanks for any help.

Yes, I am running haskell interpreter from inferior-haskell-mode. I though haskell mode had the logic to extract the source info from cabal file. On 21 Apr 2014, at 16:35, Andras Slemmer <0slemi0@gmail.com> wrote:

Are you trying to use inferior haskell mode? That operates separately from ghc-mod/cabal. In particular i think the setting you're looking for is the command to execute in the inferior process: M-x customize search for "Haskell Program Name" and change "ghci" to sth like "ghci -iwhere/my/src/are"
