checkSnapBuildPlan

Arguments

:: (HasConfig env, HasGHCVariant env)

=> Path Abs Dir

project root, used for checking out necessary files

-> [GenericPackageDescription]

-> Maybe (Map PackageName (Map FlagName Bool))

-> SnapshotDef

-> Maybe (CompilerVersion CVActual)

-> RIO env BuildPlanCheck

Check a set of GenericPackageDescriptions and a set of flags against a given snapshot. Returns how well the snapshot satisfies the dependencies of the packages.

Arguments

:: (HasConfig env, HasGHCVariant env)

=> Path Abs Dir

project root, used for checking out necessary files

-> [GenericPackageDescription]

-> NonEmpty SnapName

-> RIO env (SnapshotDef, BuildPlanCheck)

Find a snapshot and set of flags that is compatible with and matches as best as possible with the given GenericPackageDescriptions.

getToolMap :: LoadedSnapshot -> LocalPackages -> Map ExeName (Set PackageName)

Map from tool name to package providing it. This accounts for both snapshot and local packages (deps and project packages).
