type PackageId = PackageIdentifier #

Type alias so we can use the shorter name PackageId.

data PackageIdentifier #

The name and version of a package.

type PN = PackageName #

A package name.

type QPV = Qualified PV #

Qualified package version.

instI :: I -> Bool #

makeIndependent :: PN -> QPN #

Qualify a target package with its own name so that its dependencies are not required to be consistent with other targets.

primaryPP :: PackagePath -> Bool #

Is the package in the primary group of packages. This is used to determine (1) if we should try to establish stanza preferences for this goal, and (2) whether or not a user specified `--constraint` should apply to this dependency (grep `primaryPP` to see the use sites). In particular this does not include packages pulled in as setup deps.

setupPP :: PackagePath -> Bool #

Is the package a dependency of a setup script. This is used to establish whether or not certain constraints should apply to this dependency (grep `setupPP` to see the use sites).

showI :: I -> String #

String representation of an instance.

showPI :: PI QPN -> String #

String representation of a package instance.

unPN :: PN -> String #

Unpacking a package name.
