Data.GI.CodeGen.Fixups

Various fixups in the introspection data.

Documentation

dropMovedItems :: API -> Maybe API

Remove functions and methods annotated with "moved-to".

guessPropertyNullability :: (Name, API) -> (Name, API)

GObject-introspection does not currently support nullability annotations, so we try to guess the nullability from the nullability annotations of the curresponding get/set methods, which in principle should be reliable.

detectGObject :: (Name, API) -> (Name, API)

Not every interface that provides signals/properties is marked as requiring GObject, but this is necessarily the case, so fix the introspection data accordingly.

dropDuplicatedFields :: (Name, API) -> (Name, API)

Some libraries include duplicated flags by mistake, drop those.

checkClosureDestructors :: (Name, API) -> (Name, API)

Sometimes arguments are marked as being a user_data destructor, but there is no associated user_data argument. In this case we drop the annotation.

fixSymbolNaming :: (Name, API) -> (Name, API)

Some symbols have names that are not valid Haskell identifiers, fix that here.
