expand

A pretty printer for Elixir

Add to a project

mix.exs:

...
  defp deps do
    [
      {:expand, ">= 0.0.3"}
    ]
  end
...

Primitive types are printed one item per line.

For example, here is the abbreviated output for String.__info__(:functions):

> IO.puts Expand.it(String.__info__(:functions))
[
  at:
    2,
  capitalize:
    1,
  chunk:
    2,
...
]

Extension

You can create a specialized pretty printer by use-ing the Expand.Mixin, see Expand.AbstractCode for an example.
