The suggestion to use "cabal install --dependencies-only ..." instead of "cabal freeze" in that issue is really nicely presented. "cabal freeze" is close to the right thing, but it's just not as fully featured as "cabal install" (e.g. taking flags).

As for Stackage, I think it would be helpful to cache the full build plans computed for each package in Stackage. This is most of the work my Nix tooling currently does, so it would be a big time saver.

By "full build plans," do you mean the dist/setup-config file, or

something

else? That file would be problematic since it's Cabal-library-version specific IIRC. If you're looking for the full listing of deep dependencies and versions, we can extract that from the .yaml file using the technique I mentioned earlier.

Yes, I meant the full listing of deep dependencies.

I've put together a Gist with an executable that does what I described: https://gist.github.com/snoyberg/5b244331533fcb614523 You give it three arguments on the command line: * LTS version, e.g. 1.14 * Name of package being checked * true == only include dependencies of the library and executable, anything else == include test and benchmark dependencies as well If that's useful, I can package that up and put it on Hackage.
