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 :: LInstDecl (GhcPass p) -> LHsDecl (GhcPass p) Source #

mkRdrRecordCon :: LocatedN RdrName -> HsRecordBinds GhcPs -> EpAnn -> HsExpr GhcPs Source #

mkRdrRecordUpd :: Bool -> LHsExpr GhcPs -> [Fbind (HsExpr GhcPs)] -> EpAnn -> 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 #

Converts a list of LHsTyVarBndrs annotated with their Specificity to binders without annotations. Only accepts specified variables, and errors if any of the provided binders has an InferredSpec annotation.

mkGadtDecl :: SrcSpan -> [LocatedN RdrName] -> LHsSigType GhcPs -> [AddEpAnn] -> 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.

Arguments

-> Located (OrdList (LocatedN RdrName))	operators

checkContext :: LHsType GhcPs -> P (LHsContext GhcPs) Source #

Validate the context constraints and break up a context into a list of predicates.

checkEmptyGADTs :: Located ([AddEpAnn], [LConDecl GhcPs]) -> P (Located ([AddEpAnn], [LConDecl GhcPs])) Source #

Check if the gadt_constrlist is empty. Only raise parse error for `data T where` to avoid affecting existing error message, see #8258.

addFatalError :: MonadP m => PsError -> m a Source #

Add a fatal error. This will be the last error reported by the parser, and the parser will not produce any result, ending in a PFailed state.

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 #

Process the head of a type-level function/constructor application, i.e. the H in H a b c.

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

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

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

Disambiguate f @t (visible kind application)

mkHsOpTyPV :: 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)
