RubyFlux: a Ruby to Java compiler

RubyFlux is a compiler that turns a Ruby codebase into a closed set of .java source files suitable for running on any JVM with no additional runtime requirement.

A .java file is produced for the toplevel of each file and for each Ruby class declaration encountered. Methods are emitted as normal Java methods, but with an abstract implementation on RObject so all dynamic calls can simply be Java virtual calls. The rest of Ruby syntax maps to mostly what you'd expect in Java code.

Note that this is a young project and it is not yet considered stable for general use.

Getting Started

  1. Clone the repository
  2. From the repo dir, run "mvn package". You only need to do this once.
  3. Compile and/or run a target .rb file in one of several ways
    • Generate Java sources directly, compile, and run
      • jruby -I target:src/main/ruby src/main/ruby/ruby\_flux.rb target.rb
      • javac target.java
      • java target
    • Generate Java sources via the Rakefile
      • `rake compile[target.rb]
      • Sources are output to build/ in the same dir as target.rb
    • Generate, compile, and run via the Rakefile
      • `rake run[target.rb]

Usage

Here's an example session for using RubyFlux today:

# 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

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 102334155
