# Simetric [![Build Status](https://travis-ci.org/lexmag/simetric.svg)](https://travis-ci.org/lexmag/simetric)
Simetric provides facilities to perform approximate string matching and measurement of string similarity/distance.
The library is focusing on speed and completeness.
### Available metrics
* [Jaro](http://en.wikipedia.org/wiki/Jaro-Winkler_distance) (has been moved to [Elixir's standard library](https://hexdocs.pm/elixir/String.html#jaro_distance/2))
* [Jaro–Winkler](http://en.wikipedia.org/wiki/Jaro-Winkler_distance)
* [Levenshtein](http://en.wikipedia.org/wiki/Levenshtein_distance)
## Installation
Add Simetric as a dependency to your `mix.exs` file:
```elixir
defp deps do
[{:simetric, "~> 0.1.0"}]
end
```
Then, run `mix deps.get` in your shell to fetch the new dependency.
## Usage
__Jaro–Winkler:__
```elixir
Simetric.Jaro.Winkler.compare("dwayne", "duane") # => 0.8400000000000001
Simetric.Jaro.Winkler.compare("hardin", "martinez") # => 0.7222222222222222
Simetric.Jaro.Winkler.compare("same", "same") # => 1.0
```
__Levenshtein:__
```elixir
Simetric.Levenshtein.compare("gumbo", "gambol") # => 2
Simetric.Levenshtein.compare("kitten", "sitting") # => 3
```
