= Text
A collection of text algorithms.
== Usage
require 'text'
=== Levenshtein distance
Text::Levenshtein.distance('test', 'test')
# => 0
Text::Levenshtein.distance('test', 'tent')
# => 1
Text::Levenshtein.distance('test', 'testing')
# => 3
Text::Levenshtein.distance('test', 'testing', 2)
# => 2
=== Metaphone
Text::Metaphone.metaphone('BRIAN')
# => 'BRN'
Text::Metaphone.double_metaphone('Coburn')
# => ['KPRN', nil]
Text::Metaphone.double_metaphone('Angier')
# => ['ANJ', 'ANJR']
=== Soundex
Text::Soundex.soundex('Knuth')
# => 'K530'
=== Porter stemming
Text::PorterStemming.stem('abatements') # => 'abat'
=== White similarity
white = Text::WhiteSimilarity.new
white.similarity('Healed', 'Sealed') # 0.8
white.similarity('Healed', 'Help') # 0.25
