Instances

data Flag m Source

Constructors

Flag 

data FlagSafety Source

This determines how a flag should behave when Safe Haskell mode is on.

Constructors

EnablesSafe

This flag is a little bit of a hack. We give the safe haskell flags (-XSafe and -XSafeLanguage) this safety type so we can easily detect when safe haskell mode has been enable in a module pragma as this changes how the rest of the parsing should happen.

AlwaysAllowed

Flag is always allowed

RestrictedFunction

Flag is allowed but functions in a reduced way

CmdLineOnly

Flag is only allowed on command line, not in pragma

NeverAllowed

Flag isn't allowed at all
