Importing modules with ahc-link

[dduenker]

Hi, i am a bit confused as of how to use this project when i am importing packages, which are not installed by default. I have a project, which uses cassava (and also other packages) and imports it via import Data.Csv. I want to export a function from my project to use it via javascript. I am able to compile using ahc-cabal, but ahc-dist does not appear to support --export-function. How can i accomplish this with ahc-link?

ahc-link --input-hs src/Lib.hs

  | ^^^^^^^^^^^^^^^

src/Lib.hs:11:1: error:
    Could not find module ‘Data.List.Split’
    Use -v to see a list of the files searched for.

Thanks for spotting yet another missing thing in documentation..for now, you can use --ghc-option=-optl--export-function=... as additional Cabal configure flag when you're building your "executable" with ahc-cabal.

Also worth noting: the prebuilt Docker image now contains cassava in the global package database, so maybe you can try using ahc-link with the image first.
