want
Erlang and Elixir library for performing easy type conversions. The Elixir interface is now a lot more complex than the Erlang one; supporting schema-based conversions between container types along with validation and default values.
Example Usage
Basic conversion between types in Erlang.
1 = want:integer( "1" ),
1.0 = want:float( "1" ),
"1.0" = want:string( 1 ),
<<"1.0">> = want:binary( 1 ),
true = want:boolean( "true" ),
Basic conversion between types in Elixir.
{:ok, 1} = Want.integer("1")
1 = Want.integer!("1")
{:ok, 1.0} = Want.float("1")
1.0 = Want.float!("1")
{:ok, "1"} = Want.string(1)
"1" = Want.string!(1)
{:ok, true} = Want.boolean("true")
true = Want.boolean!("true")Complex type conversions in Elixir.
{:ok, 1} = Want.integer("foo", default: 1)
{:ok, [id: 1]} = Want.keywords(%{"id" => "bananas"}, %{id: [type: :integer, default: 1]})
{:ok, %{hello: "world", foo: :bar}} = Want.map(%{"hello" => "world", "foo" => "bar"}, %{hello: [], foo: [type: :atom]})
