data ModuleName

A valid Haskell module name.

fromString :: String -> ModuleName

Construct a `ModuleName` from a valid module name `String`.

This is just a convenience function intended for valid module strings. It is an error if it is used with a string that is not a valid module name. If you are parsing user input then use `Distribution.Text.simpleParse` instead.

components :: ModuleName -> [String]

The individual components of a hierarchical module name. For example

     components (fromString "A.B.C") = ["A", "B", "C"]

toFilePath :: ModuleName -> FilePath

Convert a module name to a file path, but without any file extension. For example:

     toFilePath (fromString "A.B.C") = "A/B/C"

main :: ModuleName

The module name `Main`.

simple :: String -> ModuleName
