Documentation

data ModuleRenaming Source #

Renaming applied to the modules provided by a package. The boolean indicates whether or not to also include all of the original names of modules. Thus, ModuleRenaming False [] is "don't expose any modules, and ModuleRenaming True [(Data.Bool, Bool)] is, "expose all modules, but also expose Data.Bool as Bool". If a renaming is omitted you get the DefaultRenaming.

(NB: This is a list not a map so that we can preserve order.)

Constructors

ModuleRenaming [(ModuleName, ModuleName)]	A module renaming/thinning; e.g., `(A as B, C as C)` brings `B` and `C` into scope.
DefaultRenaming	The default renaming, bringing all exported modules into scope.
HidingRenaming [ModuleName]	Hiding renaming, e.g., `hiding (A, B)`, bringing all exported modules into scope except the hidden ones.

interpModuleRenaming :: ModuleRenaming -> ModuleName -> Maybe ModuleName Source #

Interpret a ModuleRenaming as a partial map from ModuleName to ModuleName. For efficiency, you should partially apply it with ModuleRenaming and then reuse it.

defaultRenaming :: ModuleRenaming Source #

The default renaming, if something is specified in build-depends only.

isDefaultRenaming :: ModuleRenaming -> Bool Source #

Tests if its the default renaming; we can use a more compact syntax in IncludeRenaming in this case.
