Description
Pretty-printing of AST via Template Haskell. That is, the AST is first transformed into corresponding Template Haskell AST, then printed using its pretty-printer.
Synopsis
- class PrettyViaTH a
- pprint :: forall a (f :: Type -> Type) (node :: Type -> Type -> (Type -> Type) -> (Type -> Type) -> Type) pos s. (PrettyViaTH a, a ~ f (node Language Language f f), f ~ Wrap Language pos s, FullyTranslatable (ReformulationOf (On 'RecordWildCards) '[On 'NamedFieldPuns] Language Language pos s) node, FullyTranslatable (ReformulationOf (On 'NPlusKPatterns) '[On 'ViewPatterns] Language Language pos s) node, FullyTranslatable (ReformulationOf (Off 'ListTuplePuns) ('[] :: [ExtensionSwitch]) Language Language pos s) node) => a -> String
