Search for all classes whose name matches the string

Question

I would like to find all ruby ​​classes whose name matches the string (ignoring the case). This means that the string must be a substring of the class name.
Therefore, when you look for "stri", you should get the String class (among others).

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

Answer 1

 ObjectSpace.each_object(Class) .select{|klass| klass.name.downcase.include?("stri".downcase)} # => [ String, RubyToken::TkDXSTRING, RubyToken::TkDSTRING, RubyToken::TkXSTRING, RubyToken::TkSTRING ]
