mkClassDecl builds a RdrClassDecl, filling in the names for tycon and datacon by deriving them from the name of the class. We fill in the names for the tycon and datacon corresponding to the class, by deriving them from the name of the class itself. This saves recording the names in the interface file (which would be equally good).

mkInstD :: forall (p :: Pass). LInstDecl (GhcPass p) -> LHsDecl (GhcPass p) Source #

mkRdrRecordCon :: LocatedN RdrName -> HsRecordBinds GhcPs -> [AddEpAnn] -> HsExpr GhcPs Source #

mkRdrRecordUpd :: Bool -> LHsExpr GhcPs -> [Fbind (HsExpr GhcPs)] -> [AddEpAnn] -> PV (HsExpr GhcPs) Source #

setRdrNameSpace :: RdrName -> NameSpace -> RdrName Source #

This rather gruesome function is used mainly by the parser. When parsing:

data T a = T | T1 Int

we parse the data constructors as types because of parser ambiguities, so then we need to change the type constr to a data constr

The exact-name case can occur when parsing:

data [] a = [] | a : [a]

For the exact-name case we return an original name.

fromSpecTyVarBndr :: LHsTyVarBndr Specificity GhcPs -> P (LHsTyVarBndr () GhcPs) Source #

Converts LHsTyVarBndr annotated with its Specificity to one without annotations. Only accepts specified variables, and errors if the provided binder has an InferredSpec annotation.

fromSpecTyVarBndrs :: [LHsTyVarBndr Specificity GhcPs] -> P [LHsTyVarBndr () GhcPs] Source #

mkGadtDecl :: SrcSpan -> NonEmpty (LocatedN RdrName) -> EpUniToken "::" "\8759" -> LHsSigType GhcPs -> P (LConDecl GhcPs) Source #

Construct a GADT-style data constructor from the constructor names and their type. Some interesting aspects of this function:

This splits up the constructor type into its quantified type variables (if provided), context (if provided), argument types, and result type, and records whether this is a prefix or record GADT constructor. See Note [GADT abstract syntax] in GHC.Hs.Decls for more details.

hsHoleExpr :: Maybe EpAnnUnboundVar -> HsExpr GhcPs Source #

class DisambTD b where Source #

Disambiguate constructs that may appear when we do not know ahead of time whether we are parsing a type or a newtype/data constructor.

See Note [Ambiguous syntactic categories] for the general idea.

See Note [Parsing data constructors is hard] for the specific issue this particular class is solving.

Methods

mkHsAppTyHeadPV :: LHsType GhcPs -> PV (LocatedA b) Source #

mkHsAppTyPV :: LocatedA b -> LHsType GhcPs -> PV (LocatedA b) Source #

Disambiguate f x (function application or prefix data constructor).

mkHsAppKindTyPV :: LocatedA b -> EpToken "@" -> LHsType GhcPs -> PV (LocatedA b) Source #

Disambiguate f @t (visible kind application)

mkHsOpTyPV :: PromotionFlag -> LHsType GhcPs -> LocatedN RdrName -> LHsType GhcPs -> PV (LocatedA b) Source #

Disambiguate f # x (infix operator)

mkUnpackednessPV :: Located UnpackednessPragma -> LocatedA b -> PV (LocatedA b) Source #

Disambiguate {-# UNPACK #-} t (unpack/nounpack pragma)

mkTupleSyntaxTycon :: Boxity -> Int -> P RdrName Source #

Decide whether to parse tuple con syntax (,) in a type as a type or data constructor, based on the extension ListTuplePuns. The case with an explicit promotion quote, '(,), is handled by the rule SIMPLEQUOTE sysdcon_nolist in atype.

mkListSyntaxTy0 :: EpaLocation -> EpaLocation -> SrcSpan -> P (HsType GhcPs) Source #

Decide whether to parse list tycon syntax [] in a type as a type or data constructor, based on the extension ListTuplePuns. The case with an explicit promotion quote, '[], is handled by mkExplicitListTy.

mkListSyntaxTy1 :: EpaLocation -> LocatedA (HsType GhcPs) -> EpaLocation -> P (HsType GhcPs) Source #

Decide whether to parse list type syntax [Int] in a type as a type or data constructor, based on the extension ListTuplePuns. The case with an explicit promotion quote, '[Int], is handled by mkExplicitListTy.

withCombinedComments :: (HasLoc l1, HasLoc l2) => l1 -> l2 -> (SrcSpan -> P a) -> P (LocatedA a) Source #

Call a parser with a span and its comments given by a start and end token.

requireLTPuns :: PsErrPunDetails -> Located a -> Located b -> P () Source #

Emit an error of type PsErrInvalidPun with a location from start to end if the extension ListTuplePuns is disabled.

This is used in Parser.y to guard rules that require punning.
