Ruby Language Arrays Create Array of Strings
Example
Arrays of strings can be created using ruby's percent string syntax:
array = %w(one two three four)
This is functionally equivalent to defining the array as:
array = ['one', 'two', 'three', 'four']
Instead of %w() you may use other matching pairs of delimiters: %w{...}, %w[...] or %w<...>.
It is also possible to use arbitrary non-alphanumeric delimiters, such as: %w!...!, %w#...# or %w@...@.
%W can be used instead of %w to incorporate string interpolation. Consider the following:
var = 'hello'
%w(#{var}) # => ["\#{var}"]
%W(#{var}) # => ["hello"]
Multiple words can be interpreted by escaping the space with a \.
%w(Colorado California New\ York) # => ["Colorado", "California", "New York"]
