Undefined Function: init/1

Trying to use plug (0.5.3) using cowboy (1.0.0) with Elixir 0.15.0 and did hello world in the doc but getting this error:

Running with Cowboy on http://localhost:4000
== Compilation error on file lib/plug_try.ex ==

** (UndefinedFunctionError) undefined function: PlugTry.init/1

Have you defined the init/1 function in your plug? If yes, can you please post its source?

[rizafahmi]

defmodule PlugTry do
  import Plug.Conn

  def init(options) do
    options
  end

  def call(conn, _opts) do
    conn
    |> put_res_content_type("text/plain")
    |> send_resp(200, "Hello, world!")
  end

  IO.puts "Running with Cowboy on http://localhost:4000"
  Plug.Adapters.Cowboy.http PlugTry, []
end

You need to move the last two lines to outside the module, after the module is defined, otherwise it won't indeed find the functions!

My bad :)

Thanks @josevalim !
