MySQL UDF functions implemented in C for:

  • General Levenshtein algorithm
  • k-bounded Levenshtein distance algorithm (linear time, constant space),
  • Levenshtein ratio (syntactic sugar for: levenshtein_ratio(s, t) = 1 - levenshtein(s, t) / max(s.length, t.length))
  • k-bounded Levenshtein ratio

Installation instructions in the same .c file.
