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?
-
Fixed local gem install (~/.gem)
-
Fixed compilation error on no-argument static class methods that
return
reference types -
Better implicit handling of const reference types
-
Fixed potential memory leaks when dealing with Rice::Arg
-
Changed mailing list away from Google G. to http://librelist.com
Supported Platforms:
- Linux
- Mac OS X 10.5 and 10.6
- Windows with MinGW / MSYS
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)
