- Buildable package components
- Installation directories

Description

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)] Source

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

inplacePackageId :: PackageId -> InstalledPackageId Source

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.

pkgComponents :: PackageDescription -> [Component] Source

All the components in the package (libs, exes, or test suites).

pkgEnabledComponents :: PackageDescription -> [Component] Source

All the components in the package that are buildable and enabled. Thus this excludes non-buildable components and test suites or benchmarks that have been disabled.

Perform the action on each buildable `Executable` in the package description. Extended version of `withExe` that also gives corresponding build info.
