levenshtein automaton
|
|
|
|
This package makes it fast and simple to build a finite determinic automaton that computes the levenshtein distance from a given string.
|
|
|
|
# Sample usage:
|
|
|
|
```
|
|
// build a re-usable builder
|
|
lb := NewLevenshteinAutomatonBuilder(2, false)
|
|
|
|
origTerm := "couchbasefts"
|
|
dfa := lb.BuildDfa("couchbases", 2)
|
|
ed := dfa.eval([]byte(origTerm))
|
|
if ed.distance() != 2 {
|
|
log.Errorf("expected distance 2, actual: %d", ed.distance())
|
|
}
|
|
|
|
```
|
|
|
|
This implementation is inspired by [blog post](https://fulmicoton.com/posts/levenshtein/) and is intended to be
|
|
a port of original rust implementation: https://github.com/tantivy-search/levenshtein-automata
