My problem is: The checker needs to read the package description in order to classify the dependency ranges. The compiler has no access to the package description.

Right, — similar to how ghc doesn't access package description either. I guess there's no reason not to add such a feature, if you're willing to write a patch (to both haskell-packages and Cabal).

If it tries to load the package description manually, that will fail on tarballs.

Not sure what you mean here. What tarballs?

If foobar-0.2.tar.gz contains a tarball created by "cabal sdist", then I can install it via $ cabal install foobar-0.2.tar.gz In this case, cabal-install unpacks the archive, configures, builds and installs the package. It would be neat to run the pvp check in the same way: $ cabal install --haskellsuite -w check-pvp-compiler foobar-0.2.tar.gz However, this requires that check-pvp-compiler gets the path to the package description as parameter and does not try to load it from the current directory.

I can also not see how I define my own command line options in the Compiler interface.

Good point. I've added 'customMain' to git repo. Let me know if it works for you.

I'll try that.
