A Ruby static compiler.

rubyflux's Issues

Fails to properly handle raw true conditional

jruby -I target:src/main/ruby src/main/ruby/fast_ruby.rb -e "if true; puts 'yay'; else; puts 'wah?'; end"
javac DashE.java
java DashE
=> wah?

This should output yay.

undefined method `required_args' when running `rake run`

When I run rake run[fib.rb], it failed with the following information: NoMethodError: undefined method `required_args' for #Java::OrgJrubyParser::StaticScope:0x37271612
Here is detailed:

I guess it is about arguments. Thank you very much!

hello.rb test produces invalid Java source.

Running your hello.rb test through the compiler produces this:

    public RObject fib(RObject a) {
        RObject __last = RNil;
        __last = if (        __last = a.__LESS_THAN_SIGN(new RFixnum(2));
.toBoolean()) {
        __last = a;
} else {
        __last = fib(a.__HYPHEN_MINUS(new RFixnum(1))).__PLUS_SIGN(fib(a.__HYPHEN_MINUS(new RFixnum(2))));
};
        return __last;
    }

I think (from the state of lib/RString.java) that you've forgotten to git push your latest code.

Demo Fib code does not run.

Docs should mention that it's not yet stable

According to this article RubyFlux is not yet a stable thing to use. Would be useful if this gets mentioned in the README so that people are not confused. Also, references to more stable tools would be helpful.
