I'm archiving this repo because I combined this functionality in the nu_plugin_strutils nushell plugin at https://github.com/fdncred/nu_plugin_strutils

nu_plugin_str_similarity

This plugin uses the textdistance.rs crate to calculate edit distance

Usage:

Single Algorithm Usage

"nushell" | str similarity "nutshell" --algorithm levenshtein
1

All Algorithms Usage

"nushell" | str similarity "nutshell" -all
