Structs

A Perl interpreter.

This type hides a pointer to the underlying C Perl interpreter and provides a clean Swifty interface to it. It doesn’t provide any guarantees about a Perl interpreter instance aliveness and should be used only while they are provided by outer conditions. Generally it is not a problem because a Perl interpreter is only created once on startup and destroyed on shutdown of a process. In the case of an XS module an interpreter aliveness is guaranteed during the scope of an XSUB call.

Embedding a Perl interpreter

let perl = PerlInterpreter.new()
try perl.eval("print qq/OK\\n/") // Do something interesting with Perl
perl.destroy()

Writting an XS module

@_cdecl("boot_Your__Module__Name")
public func boot(_ perl: PerlInterpreter.Pointer) {
    let perl = PerlInterpreter(perl)
    // Create XSUBs
    PerlSub(name: "test", perl: perl) { () -> Void in
        print("OK")
    }
}
