fuzmatch is a library inspired by the fuzzywuzzy python library. I've used the same function name so if you want to know more about how the function works, go see the SeatGeek blog post about fuzzywuzzy.

The algorithm used in this library is the levenshtein distance but the fuzzywuzzy package use the python-Levenshtein who has a special function for the ratio where the replace operation costs 2 (in my algorithm it costs 1). So if you compare fuzzywuzzy and fuzmatch there mays be a few differences.

You need of course to set your GOPATH, otherwise you will have an error.

A simple ratio.

fuzmatch.Ratio("book", "back")
"75"

A partial ratio.

fuzmatch.PartialRatio("hello world!","hello")
"100"

A token sort ratio.

fuzmatch.TokenSortRatio("Rust vs Golang", "Golang vs Rust")
"100"

A token set ratio.

fuzmatch.TokenSetRatio("Rust from Mozilla vs Go from Google's employees", "Rust vs Go")
"100"

If you want more informations on how the function works, go see the SeatGeek blog.
