Main interface

readTargetInfos :: Verbosity -> PackageDescription -> LocalBuildInfo -> [String] -> IO [TargetInfo] Source #

Take a list of String build targets, and parse and validate them into actual TargetInfos to be builtregisteredwhatever.

readBuildTargets :: Verbosity -> 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.

Build targets

data BuildTarget Source #

A fully resolved build target.

Constructors

BuildTargetComponent ComponentName	A specific component
BuildTargetModule ComponentName ModuleName	A specific module within a specific component.
BuildTargetFile ComponentName FilePath	A specific file within a specific component.
