Commander

A command handler utility for coxir.

Usage

Let us consider the following example.

defmodule Test do
  use Coxir.Commander
  use Commands.Other

  @prefix "!"

  command ping do
    Message.reply(message, "pong!")
  end

  @channel "432535429162729494"
  command info do
    # ···
  end

  @space user: :cookies
  command eat(amount \\ 1) do
    # ···
  end

  @space :user
  @permit :KICK_MEMBERS
  command kick(reason) do
    # ···
    Member.kick(member)
  end

  @permit &is_admin?/2
  command eval(code) do
    # ···
  end
end

We may observe commands are independently configurable by the use of @space, @permit and @channel.
As their name suggest, the first one serves for namespacing, the second one allows for permission restriction
either through an atom or a custom function - in this case is_admin/2 ships with the utility, and the latter limits
the command to a specific channel. Moreover, other modules defining commands may be included with use.
