Halive can't find cabal generated Paths

[schell]

This might not be a bug so much as a misunderstanding. How do I tell halive about the Paths_my_exe module generated by cabal? I need this in order to access data files packaged with cabal.

src/Main.hs:14:8:
    Could not find module ‘Paths_gelatin_example’
    Use -v to see a list of the files searched for.

Hi Schell! : ))

Does passing the path to it as an include dir help? As in: https://github.com/lukexi/halive#passing-command-line-arguments

so like halive src/Main.hs path/where/Paths_gelative_example/lives

??

Part of the problem is that I'm not quite sure where the module lives, since it's generated by cabal (or in this case cabal via stack). I'll see what I can find and post any updates here :) I hope all is well!

Hmm, maybe something like

halive src/Main.hs `stack path --dist-dir`

?? (I haven't needed a Paths file in a while so I forget where it puts them but it's gotta be one of those stack path entries : )

I revisited this today and figured it out. The answer is to include (stack path --dist-dir)/build/autogen.

Example using fish shell:

halive app/Example.hs src/ (stack path --dist-dir)/build/autogen
