Question: how can I use 1.0 with cabal v1-style mode?
tscholak opened this issue · 5 comments
I'm have been using hie with cabal 2.4 and v1-style builds on nix for quite some time without issue. recently, however, it stopped working, and I never found out why.
Today I updated to hie 1.0 and cabal-install 3, and hie insists to use new-/v2-style builds that my project does not support. All the dependencies are fulfilled by nix in a specific way, and cabal should just use those.
How do I tell hie to use cabal in v1 mode?
ok, I've been able to make some progress by putting a hie.yaml with the following content in the folder of the library:
cradle:
cabal:
- path: "./src"
component: "lib:hasktorch"
this seems to have the desired effect. cabal is not using the cabal.project file in the repo root and does not complain about missing trivial dependencies as it would if I used cabal v2-configure.
However, hie does not work. Here's some debug output:

and then nothing more.
This is an issue for upstream and not all-hies.
However, some answers: we have essentially dropped support for cabal v1-projects. Personally, I thought that v2 also works for v1 projects, but here we go, I learned something new.
Even with hie.yaml you are using v2, since it uses cabal v2-repl to load dependencies.
We probably can patch HIE to make it work again, for now, HIE 1.0.0.0 will not work for you, afaict.
@fendor thank you, I understand. I will likely have to switch to a setup with haskell.nix and cabal.project where I can use a nix-shell that prepares the dependencies of all project packages and not only the current one.
With #64 merged, there is now a set of templates showing how to get a working project environment: https://github.com/Infinisil/all-hies/tree/master/templates
