查找名称与字符串匹配的所有类 [英] Finding all classes whose name matches a string

问题描述

我想找到所有名称与字符串匹配的ruby类(忽略大小写). 这意味着该字符串应该是类名称的子字符串.
因此，当您搜索"stri"时，您应该得到结果String(以及其他).

I would like to find all ruby classes whose name matches a string(ignoring case). That means that the string should be a substring of the class name.
So when you search for 'stri' you should get the class String (among others) as a result.

您知道一种简便且效率不高的方法吗?

Do you know a convenient and not too inefficient way to do this?

推荐答案

ObjectSpace.each_object(Class)
.select{|klass| klass.name.downcase.include?("stri".downcase)}

# => [
  String,
  RubyToken::TkDXSTRING,
  RubyToken::TkDSTRING,
  RubyToken::TkXSTRING,
  RubyToken::TkSTRING
]
