Precedence
A general-purpose pretty-printing precedence type.
Pretty-printing types
pprParendType :: Type -> SDoc Source #
pprTidiedType :: Type -> SDoc Source #
pprTCvBndr :: TyCoVarBinder -> SDoc Source #
pprTCvBndrs :: [TyCoVarBinder] -> SDoc Source #
pprSigmaType :: Type -> SDoc Source #
pprParendTheta :: ThetaType -> SDoc Source #
pprForAll :: [TyCoVarBinder] -> SDoc Source #
pprUserForAll :: [TyCoVarBinder] -> SDoc Source #
Print a user-level forall; see Note [When to print foralls] in
GHC.Iface.Type.
pprThetaArrowTy :: ThetaType -> SDoc Source #
pprParendKind :: Kind -> SDoc Source #
pprDataCons :: TyCon -> SDoc Source #
pprWithExplicitKindsWhen :: Bool -> SDoc -> SDoc Source #
Display all kind information (with -fprint-explicit-kinds) when the
provided Bool argument is True.
See Note [Kind arguments in error messages] in GHC.Tc.Errors.
pprWithTYPE :: Type -> SDoc Source #
This variant preserves any use of TYPE in a type, effectively locally setting -fprint-explicit-runtime-reps.
pprSourceTyCon :: TyCon -> SDoc Source #
Pretty-printing coercions
pprParendCo :: Coercion -> SDoc Source #
debugPprType :: Type -> SDoc Source #
debugPprType is a simple pretty printer that prints a type without going through IfaceType. It does not format as prettily as the normal route, but it's much more direct, and that can be useful for debugging. E.g. with -dppr-debug it prints the kind on type-variable occurrences which the normal route fundamentally cannot do.
Pretty-printing TyThings
pprTyThingCategory :: TyThing -> SDoc Source #
pprShortTyThing :: TyThing -> SDoc Source #
