软件简介

RubyFlux 是一个编译器，用来将 Ruby 代码转成对应的 Java 代码，并可在 JVM 中运行，而无需其他运行环境的要求。

每个 Ruby 类生成一个对应的 Java 文件。

使用示例：

# The file we want to compile

$ cat fib.rb
def fib(a)
  if a < 2
    a
  else
    fib(a - 1) + fib(a - 2)
  end
end

puts fib(40)

# First need to build the compiler's jar

$ mvn package
<maven noise>

# Provide the target file to 'rake run'.
#
# The Ruby sources are translated to .java and all support code is copied out
# of RubyFlux for the compilation step. That source is then compiled and run.
# to compile

$ rake run[fib.rb]
jruby -I target:src/main/ruby src/main/ruby/ruby_flux.rb fib.rb
javac fib.java
java fib
