  • XS? (Score:1)

    by Deprived (9179) on 2009.04.21 9:18 (#68191)
    question - do XS modules load parallel to the jvm, or are they off the table entirely?

    • Java uses JNI which is its native extension mechanism. I'm pretty sure at least basic XS modules could be compiled using a compat layer that provides XSUB.h and perl.h definitions but calls the appropriate JNI functions instead.

      (and no, I'm not volunteering)

    • It was my understanding that, like Ruby, the C extensions won't be available. That being said, I don't know that this is impossible, but it's not planned as far as I'm aware.

      Those XS extensions written in order to interface with different C libraries might be problematic. Those written for speed would be suitable candidates for rewriting as Java approaches the speed of C (and in some benchmarks can exceed it due to Java's optimizations).

      • i guess that my pipe dream of a spidermonkey perl module running inside the jvm isn't going to happen. oh well, at least there's still rhino.
