# Internals exposed for testing

selectPackageTargets :: TargetSelector -> [AvailableTarget k] -> Either ListBinTargetProblem [k] #

This defines what a `TargetSelector` means for the `list-bin` command. It selects the `AvailableTarget`s that the `TargetSelector` refers to, or otherwise classifies the problem.

For the `list-bin` command we select the exe or flib if there is only one and it's buildable. Fail if there are no or multiple buildable exe components.

selectComponentTarget :: SubComponentTarget -> AvailableTarget k -> Either ListBinTargetProblem k #

For a `TargetComponent` `TargetSelector`, check if the component can be selected.

For the `run` command we just need to check it is a executable-like (an executable, a test, or a benchmark), in addition to the basic checks on being buildable etc.
