readBuildTargets :: PackageDescription -> [String] -> IO [BuildTarget] Source #

Read a list of user-supplied build target strings and resolve them to BuildTargets according to a PackageDescription. If there are problems with any of the targets e.g. they don't exist or are misformatted, throw an IOException.

Resolving build targets

resolveBuildTargets :: PackageDescription -> [(UserBuildTarget, Bool)] -> ([BuildTargetProblem], [BuildTarget]) Source #

Given a bunch of user-specified targets, try to resolve what it is they refer to.
