Documentation
deriveAll :: [Name] -> Q [Dec] -> Q [Dec]Source

The deriveAll function takes a list of classes to derive and a block of declarations. It will additionally derive instances for Typeable, Data and New.Data.

Example: 

 $( deriveAll [''Show, ''Eq, ''Default] [d|
        data Foo a = Foo a
        data Bar = Baz | Quux
  |] )
deriveNewData :: [Name] -> Q [Dec]Source
deriveNewDataNoDefault :: [Name] -> Q [Dec]Source
