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?
* Fully compatible with Ruby 1.9.2
* Constructor now supports default arguments
* Ability to define implicit casting rules through define_implicit_cast
* Various tweaks, bug fixes, and memory management updates
Supported Platforms:
* Linux
* Mac OS X 10.5 and 10.6
* While Windows has been known to work with MinGW / MSYS, I haven't
been able to keep this testing up as of late. Would appreciate any help
here.
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>("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)
