Suddig

suddig {adj.} /²s'ɵdːɪg/

(Swedish for "fuzzy")

A fast, flexible, and modular fuzzy finder library for Go. Built for both quick, one-line matches and deep customization, suddig provides simple functions (Match, Distance, Score, FindMatches, RankMatches) for everyday use, and a fully configurable matcher package for advanced scenarios.

Features

• Modular Architecture: Swap or extend normalization, distance, and scoring components.
• Simple API: Call suddig.Match, suddig.Distance, suddig.Score, suddig.FindMatches & suddig.RankMatches out of the box.
• Advanced Configuration: Instantiate a matcher.Matcher with custom configs.Config to tweak behavior.
• Parallel Processing: Leverage all available CPU cores to perform matching and ranking in parallel—ideal for large datasets, with near-linear speedups and minimal overhead.
• Mutliple Distance Algorithms: Both Levenshtein & Damerau Levenshtein are supported out of the box, and you can easily add more.

package main

import (
	"fmt"
	"os"

	"github.com/vincbro/suddig"
)

func main() {
	args := os.Args[1:]
	argc := len(args)

	if argc < 2 {
		fmt.Println("Need 2 arguments")
		os.Exit(1)
	}
	s1, s2 := args[0], args[1]

	match := suddig.Match(s1, s2)

	if match {
		fmt.Printf("%s and %s match!\n", s1, s2)
	} else {
		fmt.Printf("%s and %s do not match\n", s1, s2)
	}
