data PackageEnvironmentType #

Type of the current package environment.

Constructors

UserPackageEnvironment | './cabal.config'
AmbientPackageEnvironment | '~.configcabal/config'

classifyPackageEnvironment :: FilePath -> IO PackageEnvironmentType #

Is there a 'cabal.config' in this directory?

readPackageEnvironmentFile :: ConstraintSource -> PackageEnvironment -> FilePath -> IO (Maybe (ParseResult PackageEnvironment)) #

Read the package environment file.

showPackageEnvironment :: PackageEnvironment -> String #

Pretty-print the package environment.

showPackageEnvironmentWithComments :: Maybe PackageEnvironment -> PackageEnvironment -> String #

Pretty-print the package environment with default values for empty fields commented out (just like the default Cabal config file).

loadUserConfig :: Verbosity -> FilePath -> Maybe FilePath -> IO SavedConfig #

Same as `userPackageEnvironmentFile`, but returns a SavedConfig.

userPackageEnvironmentFile :: FilePath #

Optional package environment file that can be used to customize the default settings. Created by the user.
