withPerl5 :: IO a -> IO a

Run a computation within the context of a Perl 5 interpreter.

callSub :: forall s a r. (ToCV s, ToArgs a, FromArgs r) => s -> a -> IO r

Call a Perl 5 subroutine.

(.:) :: (ToCV sub, ToArgs args, FromArgs ret) => sub -> args -> IO ret

(.!) :: (ToCV sub, ToArgs args) => sub -> args -> IO ()

callMethod :: forall i m a r. (ToSV i, ToSV m, ToArgs a, FromArgs r) => i -> m -> a -> IO r

Call a Perl 5 method.

(.$) :: (ToSV meth, ToArgs args, FromArgs ret) => SV -> meth -> args -> IO ret

(.$!) :: (ToSV meth, ToArgs args) => SV -> meth -> args -> IO ()

eval :: forall a. FromArgs a => String -> IO a

Evaluate a snippet of Perl 5 code.

eval_ :: String -> IO ()

Same as eval but always in void context.

type SV = Ptr ()

use :: String -> IO SV

Use a module. Returns a prototype object representing the module.
