# `useful`

A collection of useful functions for working in `Elixir`.

# Why?

We found ourselves copy-pasting a few useful "helper" functions
across our Elixir projects and it wasn't 
So we put a stop to the copy-pasting and created this library.

# What?

A library of useful functions that we need for building apps in `Elixir`.

# Who?

This library is for our use on our various `Elixir` / `Phoenix` apps.
As with everything we do it's Open Source, Tested and Documented 
so that _anyone_ can benefit from it.

# How?

## Install

The package can be installed
by adding `useful` to your list of dependencies in `mix.exs`:

def deps do
    {:useful, "~> 0.1.0"}

## Function Reference

### `atomize_map_keys/1`

Converts a `Map` that has strings as keys (or mixed keys)
to have only atoms.

# map that has different types of keys:
my_map = %{"name" => "Alex", id: 1}
%{name: Alex, id: 1}

Works recursively for deeply nested maps:

person = %{"name" => "Alex", id: 1, details: %{"age" => 17, height: 185}}
%{name: Alex, id: 1, details: %{age: 17, height: 185}}
