mkRdrGetField :: LHsExpr GhcPs -> LocatedAn NoEpAnns (DotFieldOcc GhcPs) -> HsExpr GhcPs Source #

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

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

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

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

mkHsIntegral :: IntegralLit -> HsOverLit GhcPs Source #

mkHsFractional :: FractionalLit -> HsOverLit GhcPs Source #

mkHsIsString :: SourceText -> FastString -> HsOverLit GhcPs Source #

mkHsDo :: HsDoFlavour -> LocatedLW [ExprLStmt GhcPs] -> HsExpr GhcPs Source #

mkMDo :: HsDoFlavour -> LocatedLW [ExprLStmt GhcPs] -> EpaLocation -> EpaLocation -> HsExpr GhcPs Source #

mkSpliceDecl :: LHsExpr GhcPs -> LHsDecl GhcPs Source #

mkRoleAnnotDecl :: SrcSpan -> LocatedN RdrName -> [Located (Maybe FastString)] -> (EpToken "type", EpToken "role") -> P (LRoleAnnotDecl GhcPs) Source #

mkClassDecl :: SrcSpan -> Located (Maybe (LHsContext GhcPs), LHsType GhcPs) -> Located (a, [LHsFunDep GhcPs]) -> OrdList (LHsDecl GhcPs) -> EpLayout -> AnnClassDecl -> P (LTyClDecl GhcPs) Source #

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

mkDataFamInst :: SrcSpan -> NewOrData -> Maybe (LocatedP CType) -> (Maybe (LHsContext GhcPs), HsOuterFamEqnTyVarBndrs GhcPs, LHsType GhcPs) -> Maybe (LHsKind GhcPs) -> [LConDecl GhcPs] -> Located (HsDeriving GhcPs) -> AnnDataDefn -> P (LInstDecl GhcPs) Source #

mkTySynonym :: SrcSpan -> LHsType GhcPs -> LHsType GhcPs -> EpToken "type" -> EpToken "=" -> P (LTyClDecl GhcPs) Source #

mkTyFamInstEqn :: SrcSpan -> HsOuterFamEqnTyVarBndrs GhcPs -> LHsType GhcPs -> LHsType GhcPs -> EpToken "=" -> P (LTyFamInstEqn GhcPs) Source #

mkStandaloneKindSig :: SrcSpan -> Located [LocatedN RdrName] -> LHsSigType GhcPs -> (EpToken "type", TokDcolon) -> P (LStandaloneKindSig GhcPs) Source #

mkTyFamInst :: SrcSpan -> TyFamInstEqn GhcPs -> EpToken "type" -> EpToken "instance" -> P (LInstDecl GhcPs) Source #

mkInlinePragma :: SourceText -> (InlineSpec, RuleMatchInfo) -> Maybe Activation -> InlinePragma Source #

mkOpaquePragma :: SourceText -> InlinePragma Source #

mkPatSynMatchGroup :: LocatedN RdrName -> LocatedLW (OrdList (LHsDecl GhcPs)) -> P (MatchGroup GhcPs (LHsExpr GhcPs)) Source #

mkRecConstrOrUpdate :: Bool -> LHsExpr GhcPs -> SrcSpan -> ([Fbind (HsExpr GhcPs)], Maybe SrcSpan) -> (Maybe (EpToken "{"), Maybe (EpToken "}")) -> PV (HsExpr GhcPs) Source #

mkTyClD :: forall (p :: Pass). LTyClDecl (GhcPass p) -> LHsDecl (GhcPass p) Source #

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 -> (Maybe (EpToken "{"), Maybe (EpToken "}")) -> HsExpr GhcPs Source #

mkRdrRecordUpd :: Bool -> LHsExpr GhcPs -> [Fbind (HsExpr GhcPs)] -> (Maybe (EpToken "{"), Maybe (EpToken "}")) -> PV (HsExpr GhcPs) Source #

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

This rather gruesome function is used mainly by the parser.

Case #1. 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.

Case #2. When parsing:

x = fn (forall a. a)   -- RequiredTypeArguments

we use setRdrNameSpace to set the namespace of forall-bound variables.

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.

annBinds :: EpToken "where" -> EpAnnComments -> HsLocalBinds GhcPs -> (HsLocalBinds GhcPs, Maybe EpAnnComments) Source #

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

stmtsAnchor :: forall (tok :: Symbol) a. Located (OrdList (EpToken tok), a) -> Maybe EpaLocation Source #

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

stmtsLoc :: forall (tok :: Symbol) a. Located (OrdList (EpToken tok), a) -> SrcSpan Source #

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

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

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

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) Source #

mkImport :: Located CCallConv -> Located Safety -> (Located StringLiteral, LocatedN RdrName, LHsSigType GhcPs) -> (EpToken "import", TokDcolon) -> P (EpToken "foreign" -> HsDecl GhcPs) Source #

parseCImport :: forall (p :: Pass). LocatedE CCallConv -> LocatedE Safety -> FastString -> String -> Located SourceText -> Maybe (ForeignImport (GhcPass p)) Source #

mkExport :: Located CCallConv -> (Located StringLiteral, LocatedN RdrName, LHsSigType GhcPs) -> (EpToken "export", TokDcolon) -> P (EpToken "foreign" -> HsDecl GhcPs) Source #

mkExtName :: RdrName -> CLabelString Source #

mkGadtDecl :: SrcSpan -> NonEmpty (LocatedN RdrName) -> TokDcolon -> 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.

mkConDeclH98 :: (TokDarrow, (TokForall, EpToken ".")) -> LocatedN RdrName -> Maybe [LHsTyVarBndr Specificity GhcPs] -> Maybe (LHsContext GhcPs) -> HsConDeclH98Details GhcPs -> ConDecl GhcPs Source #

checkImportDecl :: Maybe (EpToken "qualified") -> Maybe (EpToken "qualified") -> P () Source #

checkExpBlockArguments :: LHsExpr GhcPs -> PV () Source #

Yield a parse error if we have a function applied directly to a do block etc. and BlockArguments is not enabled.

checkCmdBlockArguments :: LHsCmd GhcPs -> PV () Source #

checkPrecP Source #

Check if a fixity is valid. We support bypassing the usual bound checks for some special operators.

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

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]
    (Eq a)               -->  [Eq a]
    (((Eq a)))           -->  [Eq a]
