require not working on ruby 2.0?

Question

I'm doing a test with "require" under ruby 2.0.0p576 (2014-09-19 revision 47628) [x86_64-darwin13.4.0] it doesn't work in many ways. There are two files in ruby directory as shown below:

string_extensions.rb

class String def vowels self.scan(/[aeiou]/i) end end

vowels_test.rb

require 'string_extensions' puts "This is a test".vowels.join('-')

fire up IRB

Snailwalkers-MacBook-Pro:ruby snailwalker$ ruby vowels_test.rb returs : `require': cannot load such file -- string_extensions (LoadError)

I tried to change require 'string_extensions' to " require_relative 'string_extensions' ; require './string_extensions.rb' . They all didn't work.

both return error : vowels_test.rb:1:in require_relative': /Users/snailwalker/Ruby/string_extensions.rb:1: class/module name must be CONSTANT (SyntaxError)

Your help will be greatly appreciated!

If you get the error class/module name must be CONSTANT (SyntaxError), then there is a problem with your code, not with require. — Adrian

From the last paragraph of your question, it is clear that the require is working but there is an error on line 1 of the file you are requiring. Are you sure you posted the exact contents of that file here, with no typos? — David Grayson

Thank you guys so much . I found the issue, I didn't capitalize "class string" it should be " class String" with a capitalised "S" — gqli

You can use require_relative instead:

require_relative 'string_extensions' puts "This is a test".vowels.join('-')

Or even require './string_extensions'.

Use:

ruby -I. vowels_test.rb

Automatic inclusion of the current directory in the load paths was removed in Ruby 2.
