ExFuzzywuzzy

ExFuzzyWuzzy is a fuzzy string matching library that provides many ways of calculating a matching ratio between two strings, starting from a similarity function which can be based on Levenshtein or Jaro-Winkler or a custom one.

The library is an Elixir port of SeatGeek's fuzzywuzzy.

Installation

To install ExFuzzyWuzzy, just add an entry to your mix.exs:

def deps do
  [
    {:ex_fuzzywuzzy, "~> 0.2.0"}
  ]
end

Usage

Choose the ratio function which fits best your needs among the available, providing the two strings to be matched and - if needed - overwriting options over the configured ones.

Available methods are:

• Simple ratio
• Quick ratio
• Partial ratio
• Token sort ratio
• Partial token sort ratio
• Token set ratio
• Partial token set ratio
• Best score ratio

Available options are:

• Similarity function (Levenshtein and Jaro-Winkler provided in library)
• Case sensitiveness of match
• Decimal precision of output score

Here are some examples.

Simple ratio

iex> ExFuzzywuzzy.ratio("this is a test", "this is a test!")
96.55

Quick ratio

iex> ExFuzzywuzzy.quick_ratio("this is a test", "this is a test!")
100.0

Partial ratio

iex> ExFuzzywuzzy.partial_ratio("this is a test", "this is a test!")
100.0

Best Score ratio

iex> ExFuzzywuzzy.best_score_ratio("this is a test", "this is a test!")
{:quick, 100.0}
