GHC.Iface.Type

Synopsis

Documentation

data IfaceType Source #

A kind of universal type, used for types and kinds.

Any time a Type is pretty-printed, it is first converted to an IfaceType before being printed. See Note [Pretty printing via Iface syntax] in GHC.Types.TyThing.Ppr

data IfaceTyConSort Source #

The various types of TyCons which have special, built-in syntax.

Constructors

IfaceNormalTyCon

a regular tycon

IfaceTupleTyCon !Arity !TupleSort

e.g. (a, b, c) or (#a, b, c#). The arity is the tuple width, not the tycon arity (which is twice the width in the case of unboxed tuples).

IfaceSumTyCon !Arity

e.g. (a | b | c)

IfaceEqualityTyCon

A heterogeneous equality TyCon (i.e. eqPrimTyCon, eqReprPrimTyCon, heqTyCon) that is actually being applied to two types of the same kind. This affects pretty-printing only: see Note [Equality predicates in IfaceType]

data ArgFlag Source #

Argument Flag

Is something required to appear in source Haskell (Required), permitted by request (Specified) (visible type application), or prohibited entirely from appearing in source Haskell (Inferred)? See Note [VarBndrs, TyCoVarBinders, TyConBinders, and visibility] in GHC.Core.TyCo.Rep

data AnonArgFlag Source #

The non-dependent version of ArgFlag. See Note [AnonArgFlag] Appears here partly so that it's together with its friends ArgFlag and ForallVisFlag, but also because it is used in IfaceType, rather early in the compilation chain

Constructors

VisArg

Used for (->): an ordinary non-dependent arrow. The argument is visible in source code.

InvisArg

Used for (=>): a non-dependent predicate arrow. The argument is invisible in source code.

data ShowForAllFlag Source #

Show forall flag

Unconditionally show the forall quantifier with (ShowForAllMust) or when (ShowForAllWhen) the names used are free in the binder or when compiling with -fprint-explicit-foralls.

mkIfaceTyConKind :: [IfaceTyConBinder] -> IfaceKind -> IfaceKind Source #

Build the tyConKind from the binders and the result kind. Keep in sync with mkTyConKind in GHC.Core.TyCon.

ifForAllBndrName :: IfaceForAllBndr -> IfLclName Source #

Extract the variable name from an IfaceForAllBndr.

ifTyConBinderName :: IfaceTyConBinder -> IfLclName Source #

Extract the variable name from an IfaceTyConBinder.

isIfaceLiftedTypeKind :: IfaceKind -> Bool Source #

Given a kind K, is K of the form (TYPE ('BoxedRep 'LiftedRep))?

newtype SuppressBndrSig Source #

Do we want to suppress kind annotations on binders? See Note [Suppressing binder signatures]

Constructors

SuppressBndrSig Bool 

newtype UseBndrParens Source #

Constructors

UseBndrParens Bool 

pprIfaceContext :: PprPrec -> [IfacePredType] -> SDoc Source #

Prints a context or () if empty You give it the context precedence

pprIfaceContextArr :: [IfacePredType] -> SDoc Source #

Prints "(C a, D b) =>", including the arrow. Used when we want to print a context in a type, so we use funPrec to decide whether to parenthesise a singleton predicate; e.g. Num a => a -> a

pprIfaceForAllPartMust :: [IfaceForAllBndr] -> [IfacePredType] -> SDoc -> SDoc Source #

Like pprIfaceForAllPart, but always uses an explicit forall.

pprIfaceForAll :: [IfaceForAllBndr] -> SDoc Source #

Render the "forall ... ." or "forall ... ->" bit of a type.
