Hi all, I just found out about the VM::InstructionSequence.compile method for turning Ruby code strings into ruby1.9 bytecode. Is there a standard method of de/serializing this bytecode to/from files, and is there a way of running bytecode directly? I'm looking at generating bytecode from another language to get it to run on Ruby. > **···** > > -- > James Coglan > > > **[jcoglan (James Coglan)](https://github.com/jcoglan)** > > > > jcoglan has 126 repositories available.

Well that's part of it. But, if by "generating bytecode from another language" means, for instance, executing JVM bytecodes, I don't think it will fly. The term bytecode here is being used rather generically. The YARV "bytecodes" aren't the same as the JVM bytecodes, any more than Smalltalk-80 bytecodes are the same as either. It's like the difference between an Intel and Motorola processor, both have instruction sets with binary representations, but those instruction sets aren't necessarily interchangeable. Getting another language to produce YARV bytecodes would be an exercise for the reader. > **···** > > On Mon, Apr 6, 2009 at 3:27 PM, Robert Dober \ wrote: > > > On Mon, Apr 6, 2009 at 2:48 PM, James Coglan \ \> wrote: > > \> Hi all, > > \> > > \> I just found out about the VM::InstructionSequence.compile method for > > \> turning Ruby code strings into ruby1.9 bytecode.

I meant that I'd like to try and generate YARV bytecode from non-Ruby source. Mostly a pie-in-the-sky idea, only just writing my first AST-walking interpreter, just wondering if it's possible. ---

It is a one-for-all interpreter (well, that's the aim, anyway), which began life as an April Fool's joke that someone took one step further. It officially hit version 1.0 the other day, so it should be a good example for you. By one-for-all I mean, it's a generic interpreter that can handle many languages, much like .NET and the clr, I guess. > **···** > > # ======================================================================= This email, including any attachments, is only for the intended addressee.

Having YARV/Rubinius as a backend for other languages is certainly a very reasonable idea. And if I understood correctly it is planned to be possible in the (near?) future.
