How to convert OO Perl to Java?

Question

I inherited a large monolithic body of OO Perl code that needs to be gradually converted to Java (at the request of the client). I know both languages, but I'm rusty on my Perl skills. Are there any tools (Eclipse plugins?) That you people can recommend for pain relief?

Answer 1

Does the OO code use Moose? If so, you can automatically convert class declarations using introspection.

To gradually convert Perl to Java, you can include Java code in a Perl program with Inline :: Java .

Perl JVM, , Perl Java?
