mkRdrProjection :: NonEmpty (LocatedAn NoEpAnns (DotFieldOcc GhcPs)) -> AnnProjection -> HsExpr GhcPs

type Fbind b = Either (LHsRecField GhcPs (LocatedA b)) (LHsRecProj GhcPs (LocatedA b))

mkHsOpApp :: LHsExpr GhcPs -> IdP GhcPs -> LHsExpr GhcPs -> HsExpr GhcPs

A useful function for building OpApps. The operator is always a variable, and we don't know the fixity yet.

mkHsIntegral :: IntegralLit -> HsOverLit GhcPs

mkHsFractional :: FractionalLit -> HsOverLit GhcPs

mkHsIsString :: SourceText -> FastString -> HsOverLit GhcPs

mkHsDo :: HsDoFlavour -> LocatedL [ExprLStmt GhcPs] -> HsExpr GhcPs

mkTyData :: SrcSpan -> Bool -> NewOrData -> Maybe (LocatedP CType) -> Located (Maybe (LHsContext GhcPs), LHsType GhcPs) -> Maybe (LHsKind GhcPs) -> [LConDecl GhcPs] -> Located (HsDeriving GhcPs) -> [AddEpAnn] -> P (LTyClDecl GhcPs)

mkRecConstrOrUpdate :: Bool -> LHsExpr GhcPs -> SrcSpan -> ([Fbind (HsExpr GhcPs)], Maybe SrcSpan) -> [AddEpAnn] -> PV (HsExpr GhcPs)

mkTyClD :: LTyClDecl (GhcPass p) -> LHsDecl (GhcPass p)

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)

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

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

setRdrNameSpace :: RdrName -> NameSpace -> RdrName

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)

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]

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.

annBinds :: AddEpAnn -> EpAnnComments -> HsLocalBinds GhcPs -> (HsLocalBinds GhcPs, Maybe EpAnnComments)

Add the annotation for a 'where' keyword to existing HsLocalBinds

fixValbindsAnn :: EpAnn AnnList -> EpAnn AnnList

stmtsAnchor :: Located (OrdList AddEpAnn, a) -> Maybe Anchor

The Anchor for a stmtlist is based on either the location or the first semicolon annotion.

stmtsLoc :: Located (OrdList AddEpAnn, a) -> SrcSpan

cvBindGroup :: OrdList (LHsDecl GhcPs) -> P (HsValBinds GhcPs)

cvBindsAndSigs :: OrdList (LHsDecl GhcPs) -> P (LHsBinds GhcPs, [LSig GhcPs], [LFamilyDecl GhcPs], [LTyFamInstDecl GhcPs], [LDataFamInstDecl GhcPs], [LDocDecl GhcPs])

cvTopDecls :: OrdList (LHsDecl GhcPs) -> [LHsDecl GhcPs]

Function definitions are restructured here. Each is assumed to be recursive initially, and non recursive definitions are discovered by the dependency analyser.

placeHolderPunRhs :: DisambECP b => PV (LocatedA b)

mkExtName :: RdrName -> CLabelString

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

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.

mkConDeclH98 :: [AddEpAnn] -> LocatedN RdrName -> Maybe [LHsTyVarBndr Specificity GhcPs] -> Maybe (LHsContext GhcPs) -> HsConDeclH98Details GhcPs -> ConDecl GhcPs

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

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

    (Eq a, Ord b)        -->  [Eq a, Ord b]
    Eq a                 -->  [Eq a]

hsHoleExpr :: Maybe EpAnnUnboundVar -> HsExpr GhcPs

class DisambTD b where

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)

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)

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

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

Disambiguate f @t (visible kind application)

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

Disambiguate f # x (infix operator)

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

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

mkTupleSyntaxTy :: EpaLocation -> [LocatedA (HsType GhcPs)] -> EpaLocation -> P (HsType GhcPs)

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

mkTupleSyntaxTycon :: Boxity -> Int -> P RdrName

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)

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)

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)

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

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

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.
