- base
- Cabal (only constraints in the setup-depends stanza are important)
Synopsis
Documentation
Arguments
| :: FlagAssignment | Flags to apply when configuring the project |
| -> GhcDatabase | Database containing metadata for all ghc versions to consider |
| -> GenericPackageDescription | The raw project description cabal file |
| -> Set Version | The versions of ghc that comply with the constraints of base and Cabal |
analyzePackage uses the provided flag assignment
to configure the package description.
It returns a set of all ghc versions found in the GhcDatabase that satisfy
the base and Cabal (only Cabal in setup-depends is considered) constraints.

Arguments
| :: FlagAssignment | Flags to apply when configuring the project |
| -> GhcDatabase | Database containing metadata for all known ghc versions |
| -> GenericPackageDescription | The raw project description cabal file |
| -> Version | The version of ghc the user wants to use |
| -> Bool | Returns whether the version of ghc the user wants is fine |
doesGhcVersionSupportPackage checks that the provided compiler version
is able to comply with the constraints of
base and Cabal (only Cabal in setup-depends is considered) of the package.
