1. InstalledPackageInfo :: PackageId -> LibraryName -> ComponentId -> LibraryVisibility -> UnitId -> [(ModuleName, OpenModule)] -> String -> Either License License -> ShortText -> ShortText -> ShortText -> ShortText -> ShortText -> ShortText -> ShortText -> ShortText -> ShortText -> AbiHash -> Bool -> Bool -> [ExposedModule] -> [ModuleName] -> Bool -> [FilePath] -> [FilePath] -> [FilePath] -> [FilePath] -> FilePath -> [String] -> [String] -> [String] -> [String] -> [FilePath] -> [String] -> [UnitId] -> [AbiDependency] -> [String] -> [String] -> [String] -> [FilePath] -> [String] -> [FilePath] -> [FilePath] -> Maybe FilePath -> InstalledPackageInfo

   Cabal-syntax	Distribution.InstalledPackageInfo

   No documentation available.

2. emptyInstalledPackageInfo :: InstalledPackageInfo

   Cabal-syntax	Distribution.InstalledPackageInfo

   No documentation available.

3. installedComponentId :: InstalledPackageInfo -> ComponentId

   Cabal-syntax	Distribution.InstalledPackageInfo

   No documentation available.

4. installedComponentId_ :: InstalledPackageInfo -> ComponentId

   Cabal-syntax	Distribution.InstalledPackageInfo

   No documentation available.

5. 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.

6. installedUnitId :: InstalledPackageInfo -> UnitId

   Cabal-syntax	Distribution.InstalledPackageInfo

   No documentation available.

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

   Cabal-syntax	Distribution.InstalledPackageInfo

   Return either errors, or IPI with list of warnings

8. showFullInstalledPackageInfo :: InstalledPackageInfo -> String

   Cabal-syntax	Distribution.InstalledPackageInfo

   The variant of showInstalledPackageInfo which outputs pkgroot field too.

9. showInstalledPackageInfo :: InstalledPackageInfo -> String

   Cabal-syntax	Distribution.InstalledPackageInfo

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

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

    Cabal-syntax	Distribution.InstalledPackageInfo

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