%w[ ] Non-interpolated Array of words, separated by whitespace
%W[ ] Interpolated Array of words, separated by whitespace
Использование:
p %w{one one two three 0 1 1 2 3} # = > ["one", "one", "two", "three", "0", "1", "1", "2", "3"]
p %W{one one two three 0 1 1 2 3} # = > ["one", "one", "two", "three", "0", "1", "1", "2", "3"]
p %w{C:\ C:\Windows} # => ["C: C:\\Windows"]
p %W{C:\ C:\Windows} # => ["C: C:Windows"]
Мой вопрос ... в чем разница?
