2021-04-13 11:24:24 <viluon> hi, beginner question: I just refactored my library project into multiple files. When building it with Cabal and a custom compiler, imports in the root file don't work. Why's that? https://usercontent.irccloud-cdn.com/file/5kYcLv9R/image.png

2021-04-13 11:31:12 <viluon> here's the full output of `cabal install --lib all` along with the `.project` and `.cabal` files https://paste.tomsmeding.com/hXg6Yu6D
2021-04-13 11:38:46 <merijn> viluon: Your other-modules field is empty
2021-04-13 11:39:04 <viluon> merijn: ah, I need to list all the modules in my project?
2021-04-13 11:39:07 <merijn> Yes
2021-04-13 11:39:53 <merijn> viluon: .cabal files function (among other things) as manifest file, i.e. they explicitly specify everything that is part of a package
2021-04-13 11:39:54 <viluon> hm, that's sad, surely that information is trivially inferable from the source code. Thank you though! I didn't realise that
2021-04-13 11:40:00 <viluon> I see
2021-04-13 11:40:58 <merijn> viluon: Is it trivially inferrible? Mostly, although when you work out the corner case, not as trivial as it seems at first. But it is intentionally not done, so that when you build a source tar ball with cabal you are guaranteed to only get what you explicitly include.
