PyPI Changelog Tests License

Datasette plugin that adds custom SQL functions for fuzzy string matching, built on top of the Jellyfish Python library by James Turk and Michael Stephens.

Interactive demos:

Examples:

SELECT soundex("hello");
    -- Outputs H400
SELECT metaphone("hello");
    -- Outputs HL
SELECT nysiis("hello");
    -- Outputs HAL
SELECT match_rating_codex("hello");
    -- Outputs HLL
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

See the Jellyfish documentation for an explanation of each of these functions.
