Distribution.Simple.LocalBuildInfo

Once a package has been configured we have resolved conditionals and dependencies, configured the compiler and other needed external programs. The LocalBuildInfo is used to hold all this information. It holds the install dirs, the compiler, the exact package dependencies, the configured programs, the package database to use and a bunch of miscellaneous configure flags. It gets saved and reloaded from a file (dist/setup-config). It gets passed in to very many subsequent build actions.

externalPackageDeps :: LocalBuildInfo -> [(InstalledPackageId, PackageId)]

External package dependencies for the package as a whole. This is the union of the individual componentPackageDeps, less any internal deps.

inplacePackageId :: PackageId -> InstalledPackageId

The installed package Id we use for local packages registered in the local package db. This is what is used for intra-package deps between components.
