1. installedComponentId_ :: InstalledPackageInfo -> ComponentId

   Cabal-syntax	Distribution.InstalledPackageInfo

   No documentation available.

2. installedOpenUnitId :: InstalledPackageInfo -> OpenUnitId

   Cabal-syntax	Distribution.InstalledPackageInfo

   Get the indefinite unit identity representing this package. This IS NOT guaranteed to give you a substitution; for instantiated packages you will get DefiniteUnitId (installedUnitId ipi). For indefinite libraries, however, you will correctly get an OpenUnitId with the appropriate OpenModuleSubst.

3. installedUnitId :: InstalledPackageInfo -> UnitId

   Cabal-syntax	Distribution.InstalledPackageInfo

   No documentation available.

4. parseInstalledPackageInfo :: ByteString -> Either (NonEmpty String) ([String], InstalledPackageInfo)

   Cabal-syntax	Distribution.InstalledPackageInfo

   Return either errors, or IPI with list of warnings

5. showFullInstalledPackageInfo :: InstalledPackageInfo -> String

   Cabal-syntax	Distribution.InstalledPackageInfo

   The variant of showInstalledPackageInfo which outputs pkgroot field too.

6. showInstalledPackageInfo :: InstalledPackageInfo -> String

   Cabal-syntax	Distribution.InstalledPackageInfo

   Pretty print InstalledPackageInfo. pkgRoot isn't printed, as ghc-pkg prints it manually (as GHC-8.4).

7. showInstalledPackageInfoField :: String -> Maybe (InstalledPackageInfo -> String)

   Cabal-syntax	Distribution.InstalledPackageInfo

   >>> let ipi = emptyInstalledPackageInfo { maintainer = fromString "Tester" }
   
   >>> fmap ($ ipi) $ showInstalledPackageInfoField "maintainer"
   Just "maintainer: Tester"
   

8. showSimpleInstalledPackageInfoField :: String -> Maybe (InstalledPackageInfo -> String)

   Cabal-syntax	Distribution.InstalledPackageInfo

   No documentation available.

9. class HasUnitId pkg => PackageInstalled pkg

   Cabal-syntax	Distribution.Package

   Class of installed packages. The primary data type which is an instance of this package is InstalledPackageInfo, but when we are doing install plans in Cabal install we may have other, installed package-like things which contain more metadata. Installed packages have exact dependencies installedDepends.

10. installedDepends :: PackageInstalled pkg => pkg -> [UnitId]

    Cabal-syntax	Distribution.Package

    No documentation available.
