Re: Ruby App Distribution

http://wiki.jruby.org/wiki/JRub... I was looking through the information there. There seems to be a lot it doesn't support.

<Excerpt>
Notable things that do not compile in either safe or unsafe mode:

class and module definitions
singleton class and method definitions
blocks with arguments
method defs with optional, "rest", or block arguments
some method calls are unsafe, like "block_given?" and "local_variables"
splats and multiple assignment (a, b = b, a)

I'd prefer to stick with the official implementation if possible. JRuby doesn't support C extensions. I was hoping to use wxRuby for a GUI.

I'm not looking to distribute anything before the next release. I don't know if something is being added with Yarv to aide in distribution. Any info would be great.


Using JRuby you can package up a Ruby app and distribute it as a
clickable jar file.

That's old, thanks for calling my attention to it. The JRuby compiler
has been complete for about a month, and can compile all Ruby code in
the stdlib (so it's pretty solid).

If you're interested in a cross-platform GUI library, there's a number
of frameworks for building Swing-based apps. Write it, package it up
into a JAR file, and anyone with Java can run it without trouble. To me,
it seems like the best/easiest way to get a cross-platform Ruby GUI app.

Actually, it's also worth mentioning that JRuby's had an interpreted
mode (similar to Ruby 1.8.x) forever, so you don't even need to compile
the Ruby code to run it. It just works, pretty much like running the C
implementation. And as it runs, JRuby will compile it for you, resulting
in performance improving at runtime.
