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 :: HsStmtContext Name -> [ExprLStmt GhcPs] -> HsExpr GhcPs Source #

mkSpliceDecl :: LHsExpr GhcPs -> HsDecl GhcPs Source #

mkRoleAnnotDecl :: SrcSpan -> Located RdrName -> [Located (Maybe FastString)] -> P (LRoleAnnotDecl GhcPs) Source #

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

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

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

mkTySynonym :: SrcSpan -> LHsType GhcPs -> LHsType GhcPs -> P (LTyClDecl GhcPs) Source #

mkTyFamInstEqn :: Maybe [LHsTyVarBndr GhcPs] -> LHsType GhcPs -> LHsType GhcPs -> P (TyFamInstEqn GhcPs, [AddAnn]) Source #

mkStandaloneKindSig :: SrcSpan -> Located [Located RdrName] -> LHsKind GhcPs -> P (LStandaloneKindSig GhcPs) Source #

mkTyFamInst :: SrcSpan -> TyFamInstEqn GhcPs -> P (LInstDecl GhcPs) Source #

mkFamDecl :: SrcSpan -> FamilyInfo GhcPs -> LHsType GhcPs -> Located (FamilyResultSig GhcPs) -> Maybe (LInjectivityAnn GhcPs) -> P (LTyClDecl GhcPs) Source #

mkLHsSigType :: LHsType GhcPs -> LHsSigType GhcPs Source #

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

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

mkRecConstrOrUpdate :: LHsExpr GhcPs -> SrcSpan -> ([LHsRecField GhcPs (LHsExpr GhcPs)], Maybe SrcSpan) -> PV (HsExpr GhcPs) Source #

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

mkRdrRecordCon :: Located RdrName -> HsRecordBinds GhcPs -> HsExpr GhcPs Source #

mkRdrRecordUpd :: LHsExpr GhcPs -> [LHsRecUpdField GhcPs] -> 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.

filterCTuple :: RdrName -> RdrName Source #

Replaces constraint tuple names with corresponding boxed ones.

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

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

mkImport :: Located CCallConv -> Located Safety -> (Located StringLiteral, Located RdrName, LHsSigType GhcPs) -> P (HsDecl GhcPs) Source #

parseCImport :: Located CCallConv -> Located Safety -> FastString -> String -> Located SourceText -> Maybe ForeignImport Source #

mkExport :: Located CCallConv -> (Located StringLiteral, Located RdrName, LHsSigType GhcPs) -> P (HsDecl GhcPs) Source #

mkExtName :: RdrName -> CLabelString Source #

mkGadtDecl :: [Located RdrName] -> LHsType GhcPs -> (ConDecl GhcPs, [AddAnn]) Source #

mkConDeclH98 :: Located RdrName -> Maybe [LHsTyVarBndr GhcPs] -> Maybe (LHsContext GhcPs) -> HsConDeclDetails GhcPs -> ConDecl GhcPs Source #

checkImportDecl :: Maybe (Located Token) -> Maybe (Located Token) -> 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.

checkPrecP Source #

Arguments

:: Located (SourceText, Int)

precedence

-> Located (OrdList (Located RdrName))

operators

-> P () 

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

checkContext :: LHsType GhcPs -> P ([AddAnn], 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]

checkPattern :: Located (PatBuilder GhcPs) -> P (LPat GhcPs) Source #

checkPattern_msg :: SDoc -> PV (Located (PatBuilder GhcPs)) -> P (LPat GhcPs) Source #

isBangRdr :: RdrName -> Bool Source #

isTildeRdr :: RdrName -> Bool Source #

checkMonadComp :: PV (HsStmtContext Name) Source #

Check for monad comprehensions

If the flag MonadComprehensions is set, return a MonadComp context, otherwise use the usual ListComp context

checkValDef :: SrcStrictness -> Located (PatBuilder GhcPs) -> Maybe (LHsType GhcPs) -> Located (a, GRHSs GhcPs (LHsExpr GhcPs)) -> P ([AddAnn], HsBind GhcPs) Source #

checkValSigLhs :: LHsExpr GhcPs -> P (Located RdrName) Source #

type LRuleTyTmVar = Located RuleTyTmVar Source #

data RuleTyTmVar Source #

Essentially a wrapper for a RuleBndr GhcPs

Constructors

mkRuleBndrs :: [LRuleTyTmVar] -> [LRuleBndr GhcPs] Source #

mkRuleTyVarBndrs :: [LRuleTyTmVar] -> [LHsTyVarBndr GhcPs] Source #

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

checkRecordSyntax :: (MonadP m, Outputable a) => Located a -> m (Located a) Source #

checkEmptyGADTs :: Located ([AddAnn], [LConDecl GhcPs]) -> P (Located ([AddAnn], [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 => SrcSpan -> SDoc -> 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.

hintBangPat :: SrcSpan -> PatBuilder GhcPs -> PV () Source #

Hint about bang patterns, assuming BangPatterns is off.

data TyEl Source #

Either an operator or an operand.

Methods

ppr :: TyEl -> SDoc Source #

pprPrec :: Rational -> TyEl -> SDoc Source #

mergeOps :: [Located TyEl] -> P (LHsType GhcPs) Source #

Merge a reversed and non-empty soup of operators and operands into a type.

User input: F x y + G a b * X Input to mergeOps: [X, *, b, a, G, +, y, x, F] Output corresponds to what the user wrote assuming all operators are of the same fixity and right-associative.

It's a bit silly that we're doing it at all, as the renamer will have to rearrange this, and it'd be easier to keep things separate.

See Note [Parsing data constructors is hard]

mergeDataCon :: [Located TyEl] -> P (Located RdrName, HsConDeclDetails GhcPs, Maybe LHsDocString) Source #

Merge a reversed and non-empty soup of operators and operands into a data constructor.

User input: C !A B -- ^ doc Input to mergeDataCon: ["doc", B, !, A, C] Output: (C, PrefixCon [!A, B], "doc")
