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 "DRY". 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"}
  ]
end

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}
Useful.atomize_map_keys(my_map)
%{name: Alex, id: 1}

Works recursively for deeply nested maps:

person = %{"name" => "Alex", id: 1, details: %{"age" => 17, height: 185}}
Useful.atomize_map_keys(my_map)
%{name: Alex, id: 1, details: %{age: 17, height: 185}}
