RubyInline 介绍

RubyInline允许你在ruby代码中直接编写c/c++代码，还会有性能问题吗？

安装方法：sudo gem install RubyInline

示例代码：

class MyTest

  def factorial(n)  
    f = 1  
    n.downto(2) { |x| f *= x }  
    f  
  end

  inline do |builder|  
    builder.c "  
    long factorial_c(int max) {  
      int i=max, result=1;  
      while (i >= 2) { result *= i--; }  
      return result;  
    }"  
  end  
end
