是否有较短的方法要求在ruby的同一目录中有文件? [英] Is there a shorter way to require a file in the same directory in ruby?

问题描述

是否有较短的方法要求文件位于与执行脚本相同的目录中?

Is there a shorter way to require a file located in the same directory (as the script being executed)?

require File.expand_path(File.dirname(__FILE__) + '/some_other_script')

我了解到require "my_script"和require "./my_script"实际上将两次加载脚本(ruby无法识别它实际上是同一脚本)，这就是推荐使用File.expand_path的原因:如果每次使用File.expand_path需要脚本的时间，则只会加载一次.

I read that require "my_script" and require "./my_script" will actually load the script twice (ruby will not recognize that it is actually the same script), and this is the reason why File.expand_path is recommended: if it is used every time the script is required, then it will only be loaded once.

在我看来很奇怪，像Ruby这样的简洁语言似乎没有更短的解决方案.例如，python就是这样:

It seems weird to me that a concise language like Ruby does not seem to have a shorter solution. For example, python simply has this:

import .some_other_module_in_the_same_directory

我想我可以猴子补丁require ...但是那简直是邪恶的！ ;-)

I guess I could monkey-patch require... but that's just evil! ;-)

推荐答案

从ruby 1.9开始，您可以使用require_relative.

Since ruby 1.9 you can use require_relative.
