Re: Compile Ruby Code?

Unless (or until) a reverse-compiler were created (which probably
would not be a high priority at first) there wouldn't be an easy way
to reverse it. However, Java bytecode isn't terribly complicated, and
the source for the compiler would be open, so eventually someone would
be able to reverse the process.

If you are looking to protect Ruby code this way, an additional
obfuscation step might be your best bet, so that even if the code were
decompiled it would be unreadable. An obfuscator that takes existing
Java classes and mutilates them might also be an option. This would
obviously make debugging more difficult, and we do not have plans to
write an obfuscator at this time.
