# Countriex

A pure elixir port of the ruby [countries](https://github.com/hexorx/countries) gem that provides all sorts of useful information about every country packaged as convenient little country structs. It includes data from ISO 3166 (countries and states/subdivisions), ISO 4217 (currency), and E.164 (phone numbers).

## Installation

Add `countriex` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [{:countriex, "~> 0.1.0"}]
end
```

## Usage

To get all country information:

```elixir
Countriex.all
```

The `get_by/2` method can be used to retrieve the first matching country for any given criteria, for example:

```elixir
Countriex.get_by(:alpha2, "US")           # %Countriex.Country{name: "United States", alpha2: "US", alpha3: "USA", ...}
Countriex.get_by(:name, "United Kingdom") # %Countriex.Country{alpha2: "GB", alpha3: "GBR", ...}
```

The `filter/2` method can be used to retrieve all countries matching the given criteria:

```elixir
Countriex.get_by(:region, "Oceania") # [%Countriex.Country{name: "Kiribati", ...}, %Countriex.Country{name: "American Samoa", ...}, ...]
Countriex.get_by(:eu_member, true)   # [%Countriex.Country{name: "Luxembourg", ...}, %Countriex.Country{name: "Poland", ...}, ...]
```

See the fields in the `Countriex.Country` struct for all possible field names that can be used for the above methods.

## Development

Run the following mix task to re-generate the country data.

```
mix countriex.generate_data
```
