Defines a package identifier along with a parser and pretty printer for it.
PackageIdentifier
s consist of a name and an exact version. It also defines
a Dependency
data type. A dependency is a package name and a version
range, like "foo >= 1.2 && < 2"
.

Class of things that have a PackageIdentifier
Types in this class are all notions of a package. This allows us to have different types for the different phases that packages go though, from simple name/id, package description, configured or installed packages.
Not all kinds of packages can be uniquely identified by a
PackageIdentifier
. In particular, installed packages cannot, there may be
many installed instances of the same source package.
packageId :: pkg -> PackageIdentifier #
packageName :: Package pkg => pkg -> PackageName #
packageVersion :: Package pkg => pkg -> Version #
class HasMungedPackageId pkg where #
mungedId :: pkg -> MungedPackageId #
mungedName' :: HasMungedPackageId pkg => pkg -> MungedPackageName #
mungedVersion' :: HasMungedPackageId munged => munged -> Version #
class Package pkg => HasUnitId pkg where #
Packages that have an installed unit ID
installedUnitId :: pkg -> UnitId #

installedPackageId :: HasUnitId pkg => pkg -> UnitId #
Deprecated: Use installedUnitId instead. This symbol will be removed in Cabal-3.0 (est. Oct 2018).
Compatibility wrapper for Cabal pre-1.24.
class HasUnitId pkg => PackageInstalled pkg where #
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
.
