Rice: Ruby Interface for C++ Extensions

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’s New?

  • Rice::Director - Seemless Polymorphism across C++ and Ruby (named
    after
    SWIG_Director)
  • Default Arguments
  • Removed explicit self requirement for global / module functions
  • Various bug fixes

Supported Platforms:

  • Linux
  • Mac OS X 10.5 and 10.6

Windows support is iffy right now. Waiting to see how the mingw build
of
Ruby comes along.

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>
#include <rice/Constructor.hpp>

class MyWrapper {
public:
MyWrapper() { }

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

};

extern “C”
void Init_wrapper()
{
define_class(“MyWrapper”)
.define_constructor(Constructor())
.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)
