fails to extend String class

[aspiers]

Same issue on Ruby 2.4.1 and 2.2.1. Looks like some module namespacing issue.

$ bundle exec irb
2.4.1 :001 > require 'word_wrap/core_ext'
 => true
2.4.1 :002 > "laksjdf laksdflkasdf".wrap
NameError: uninitialized constant String::WordWrap

Ahh I see, you have to require 'word_wrap' first. I'd argue that's a usability bug ;-)

[erikw]

To summarize, both requires are needed. This works:

irb(main):001:0> require "word_wrap"
=> true
irb(main):002:0> require "word_wrap/core_ext"
=> true
irb(main):003:0> "123 456 789".wrap 5
=> "123\n456\n789\n"

@aspiers I think this issue can be closed
