If you have an executable called "foo" and a testsuite called "foo", then "foo:name" currently refers to the executable and there is no way to get the name of the testsuite.

Best way to solve this is probably to add another optional prefix, so you can say (eg) "executable:foo:name" and "testsuite:foo:name".

Would be nice if there was something like cabal-info executables to list the names of the executables.

Would be nice to get the description and default value of a flag. This doesn't nicely fit into use of a PackageDescription though, need to get those from the GenericPackageDescription.

See discussion in https://www.reddit.com/r/haskell/comments/43w90v/cabalinfo_get_information_from_cabal_files/

If flag processing is added (#2), then it might be nice to just dump a pretty-printed cabal file with the flags applied, so you can easily see the effects of different flags.

Currently flattenPackageDescription is used, which just merges everything.

I was skimming the cabal source code, and it mentions that finalizePackageDescription is deprecated and now assumes certain artifacts are always not buildable. I am not sure if that has a direct effect on the values you are displaying.

Also, package level build-depends is overshadowing library/exe level build-depends, I believe.

Currently the build platform is used. This is a reasonable default (although the host platform would be even better), but it would be nice to have it as a parameter.

These come up if a field isn't there, but doesn't get a Maybe value (eg, the description or copyright fields). Could special-case [""], but just stripping trailing empty lines might be nicer.
