相当于Ruby中的`if __name__ =='__main __'` [英] `if __name__ == '__main__'` equivalent in Ruby

问题描述

我是Ruby的新手.我正在从包含要继续单独使用的工具的模块中导入功能.在Python中，我只需要这样做:

I am new to Ruby. I'm looking to import functions from a module that contains a tool I want to continue using separately. In Python I would simply do this:

def a():
    ...
def b():
    ...
if __name__ == '__main__':
    a()
    b()

这使我可以运行程序或将其导入为模块，以分别使用a()和/或b(). Ruby中的等效范例是什么?

This allows me to run the program or import it as a module to use a() and/or b() separately. What's the equivalent paradigm in Ruby?

推荐答案

在Ruby中，我从野外看到(当然，不是一吨)，这不是标准的Ruby设计模式.模块和脚本应该保持独立，因此，如果没有真正好的，干净的方法，我也不会感到惊讶.

From the Ruby I've seen out in the wild (granted, not a ton), this is not a standard Ruby design pattern. Modules and scripts are supposed to stay separate, so I wouldn't be surprised if there isn't really a good, clean way of doing this.

编辑:但这绝对不常见.
