pprHsForAll :: OutputableBndrId (GhcPass p) => [LHsTyVarBndr (GhcPass p)] -> LHsContext (GhcPass p) -> SDoc

Prints a forall; When passed an empty list, prints forall. only when -dppr-debug

pprHsForAllExtra :: OutputableBndrId (GhcPass p) => Maybe SrcSpan -> [LHsTyVarBndr (GhcPass p)] -> LHsContext (GhcPass p) -> SDoc

Version of pprHsForAll that can also print an extra-constraints wildcard, e.g. _ => a -> Bool or (Show a, _) => a -> String. This underscore will be printed when the 'Maybe SrcSpan' argument is a Just containing the location of the extra-constraints wildcard. A special function for this is needed, as the extra-constraints wildcard is removed from the actual context and type, and stored in a separate field, thus just printing the type will not print the extra-constraints wildcard.

pprHsExplicitForAll :: OutputableBndrId (GhcPass p) => Maybe [LHsTyVarBndr (GhcPass p)] -> SDoc

Version of pprHsForall or pprHsForallExtra that will always print forall. when passed Just []. Prints nothing if passed Nothing

pprLHsContext :: OutputableBndrId (GhcPass p) => LHsContext (GhcPass p) -> SDoc

hsTypeNeedsParens :: PprPrec -> HsType pass -> Bool

hsTypeNeedsParens p t returns True if the type t needs parentheses under precedence p.

parenthesizeHsType :: PprPrec -> LHsType (GhcPass p) -> LHsType (GhcPass p)

parenthesizeHsType p ty checks if hsTypeNeedsParens p ty is true, and if so, surrounds ty with an HsParTy. Otherwise, it simply returns ty.

parenthesizeHsContext :: PprPrec -> LHsContext (GhcPass p) -> LHsContext (GhcPass p)

parenthesizeHsContext p ctxt checks if ctxt is a single constraint c such that hsTypeNeedsParens p c is true, and if so, surrounds c with an HsParTy to form a parenthesized ctxt. Otherwise, it simply returns ctxt unchanged.
