Class Method Details

.sliding(string, n) ⇒ Object

Public: create a sliding window of ngrams from a string

string: The String to slide over n: The Integer defining the size of the ngrams

Examples

sliding('01234', 2)
# => ['01', '12', '23', '34']

# File 'lib/entropic.rb', line 22

def self.sliding(string, n)
  (0..string.length - n).map { |i| (string[i, n]).to_s }
end
