cabal index doesn't provide necessary info #29

Closed Freed-Wu closed 9 months ago

Freed-Wu commented 9 months ago

According to https://github.com/berberman/arch-hs/issues/84, cabal index doesn't provide necessary info.

I'm not sure what this means. I think what the other person meant is that Cabal doesnt provide this info in general, so you have to run a separate command to expose the info to arch-hs. I think you have to call gen-setup before running the command that's failing. It's not a bug in toml-reader, you have to do this for any package that doesnt provide Setup.hs (which is an optional file)

@felixonmars so It's also not the bug of tmol-reader? Is it possible to gen-setup automatically in PKGBUILD generated by arch-hs.

felixonmars commented 9 months ago

@Freed-Wu It's not a bug of any individual packages not providing Setup.hs. It's also not possible for arch-hs to know whether gen-setup is needed because the Cabal index doesn't carry information about it (and downloading the tarball to analyze is way more expensive). So I don't really see how we could improve the situation :(
