Description

Types for interfacing with an embedded Perl interpreter.

Synopsis

Basic types

(pointer to a) scalar value.

Instances

Eq SV Source #
Methods (==) :: SV -> SV -> Bool # (/=) :: SV -> SV -> Bool #
Show SV Source #
Methods showsPrec :: Int -> SV -> ShowS # show :: SV -> String # showList :: [SV] -> ShowS #
FromSV SV Source #
Methods fromSV :: SV -> IO SV Source #
ToSV SV Source #
Methods toSV :: SV -> IO SV Source #

(pointer to an) array value.

Instances

Eq AV Source #
Methods (==) :: AV -> AV -> Bool # (/=) :: AV -> AV -> Bool #
Show AV Source #
Methods showsPrec :: Int -> AV -> ShowS # show :: AV -> String # showList :: [AV] -> ShowS #

(pointer to a) code value.

Instances

Eq CV Source #
Methods (==) :: CV -> CV -> Bool # (/=) :: CV -> CV -> Bool #
Show CV Source #
Methods showsPrec :: Int -> CV -> ShowS # show :: CV -> String # showList :: [CV] -> ShowS #

(pointer to a) Perl interpreter instance.

Instances

Eq Interpreter Source #
Methods (==) :: Interpreter -> Interpreter -> Bool # (/=) :: Interpreter -> Interpreter -> Bool #
Show Interpreter Source #
Methods showsPrec :: Int -> Interpreter -> ShowS # show :: Interpreter -> String # showList :: [Interpreter] -> ShowS #

type of a callback from Perl into Haskell.

Calling context

Perl's calling context.

Constructors

Instances

Enum Context Source #
Methods succ :: Context -> Context # pred :: Context -> Context # toEnum :: Int -> Context # fromEnum :: Context -> Int # enumFrom :: Context -> [Context] # enumFromThen :: Context -> Context -> [Context] # enumFromTo :: Context -> Context -> [Context] # enumFromThenTo :: Context -> Context -> Context -> [Context] #
Eq Context Source #
Methods (==) :: Context -> Context -> Bool # (/=) :: Context -> Context -> Bool #
Show Context Source #
Methods showsPrec :: Int -> Context -> ShowS # show :: Context -> String # showList :: [Context] -> ShowS #

Convert a Context to an integral value that can be passed to the C API.

Used by the various "call_..." and "eval_..." Perl functions (which then pass it on to whatever code is being called).

Underlying C integer type used by Perl. ("IV" = "Integer value".)

Underlying C floating-point type used by Perl. ("NV" = "Numeric value".)
