Hi all,

Am I missing something which necessitates using only the FilePath?

Adding extra info is absolutely fine, it's just that I never needed it. What do you want to add?

Well, I'd like to split up the "get all the information we need" bit from the individual commands. That would perhaps make it easier to validate things like "does GHC_PACKAGE_PATH [or whatever] point at an existing directory" in a consistent manner across all commands and thus hopefully provide better feedback for broken setups/environments. (I also tend to find it good "hygiene" to split things up this way, but that's perhaps more a matter of taste.) See e.g. the issue I pointed to: https://github.com/haskell/cabal/issues/2381 (I don't think a full solution is possible at this time due to the fact that the env variables are only retrieved in the "exec" subcommand). Regards,
