  text:
    github: johnjansen/text

Usage

require "text"

Levenshtein distance

You should use the Levenshtein module in the Crystal StdLib though ...

  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
