Datasette plugin that adds custom SQL functions for fuzzy string matching, built on top of the [Jellyfish](https://github.com/jamesturk/jellyfish) Python library by James Turk and Michael Stephens.

Interactive demos:

* [soundex, metaphone, nysiis, match_rating_codex comparison](https://latest-with-plugins.datasette.io/fixtures?sql=SELECT%0D%0A++++soundex%28%3As%29%2C+%0D%0A++++metaphone%28%3As%29%2C+%0D%0A++++nysiis%28%3As%29%2C+%0D%0A++++match_rating_codex%28%3As%29&s=demo).
* [distance functions comparison](https://latest-with-plugins.datasette.io/fixtures?sql=SELECT%0D%0A++++levenshtein_distance%28%3As1%2C+%3As2%29%2C%0D%0A++++damerau_levenshtein_distance%28%3As1%2C+%3As2%29%2C%0D%0A++++hamming_distance%28%3As1%2C+%3As2%29%2C%0D%0A++++jaro_similarity%28%3As1%2C+%3As2%29%2C%0D%0A++++jaro_winkler_similarity%28%3As1%2C+%3As2%29%2C%0D%0A++++match_rating_comparison%28%3As1%2C+%3As2%29%3B&s1=barrack+obama&s2=barrack+h+obama)

Examples:

    SELECT soundex(""hello"");
        -- Outputs H400
    SELECT metaphone(""hello"");
        -- Outputs HL
    SELECT nysiis(""hello"");
        -- Outputs HAL
    SELECT match_rating_codex(""hello"");
        -- Outputs HLL
    SELECT porter_stem(""running"");
        -- Outputs run
    SELECT levenshtein_distance(""hello"", ""hello world"");
        -- Outputs 6
    SELECT damerau_levenshtein_distance(""hello"", ""hello world"");
        -- Outputs 6
    SELECT hamming_distance(""hello"", ""hello world"");
        -- Outputs 6
    SELECT jaro_similarity(""hello"", ""hello world"");
        -- Outputs 0.8181818181818182
    SELECT jaro_winkler_similarity(""hello"", ""hello world"");
        -- Outputs 0.890909090909091
    SELECT match_rating_comparison(""hello"", ""helloo"");
        -- Outputs 1
