Rice: Ruby Interface for C++ Extensions
========================================

Change Log:

* Fixed x86_64 bit install bug with -fPIC
* Fixed the tarball and zip file, they were missing an essential
configuration file.


What is Rice?

Rice is a C++ interface to Ruby's C API.  It provides a type-safe and
exception-safe interface in order to make embedding Ruby and writing
Ruby extensions with C++ easier.  It is similar to Boost.Python in many
ways, but also attempts to provide an object-oriented interface to all
of the Ruby C API.

What Rice gives you:
* A simple C++-based syntax for wrapping and defining classes
* Automatic conversion of exceptions between C++ and Ruby
* Smart pointers for handling garbage collection
* Wrappers for most builtin types to simplify calling code

How do you get Rice?

 gem install rice

Note: Rice does require a C++ compiler. See the Documentation page for
more details.


How simple of a syntax?

wrapper.cpp

 #include "rice/Class.hpp"

 class MyWrapper {
  public:
    MyWrapper() { }

    void doThis() { }
    int doThat(int a, float b) { }
 };

 extern "C"
 void Init_wrapper()
 {
  define_class<MyWrapper>("MyWrapper")
   .define_constructor(Constructor<MyWrapper>())
   .define_method("do_this", &MyWrapper::doThis)
   .define_method("do_that", &MyWrapper::doThat);
 }

extconf.rb

 require 'mkmf-rice'
 create_makefile("wrapper")

test.rb

 require 'wrapper'
 c = MyWrapper.new
 c.do_this
 c.do_that(1, 2.0)

Building Ruby extensions have never been so easy!
