Extension

Extension allows you to seperate your code from the main application.

@since

Make a new extension

Make a new class that extends Extension.

class MyExtension < Discorb::Extension
  # ...
end

Register Event

Use Discorb::Extension.event to register event, or Discorb::Extension.once_event to register event only once.

class MyExtension < Discorb::Extension
  event :message do |message|
    # ...
  end

  once_event :standby do |message|
    # ...
  end
end

Note block will be binded to the extension instance.

Register Command

Use Discorb::Extension.command to register command, see Discorb::ApplicationCommand::Handler for more information.

class MyExtension < Discorb::Extension
  slash("command", "Command") do |interaction|
    # ...
  end

  slash_group("group", "Group") do |group|
    group.slash("subcommand", "Subcommand") do |interaction|
      # ...
    end

    group.group("subgroup", "Subcommand group") do |group|
      group.slash("group_subcommand", "Command in Subcommand group") do |interaction|
        # ...
      end
    end
  end
end

Load extension

Use Discorb::Client#load_extension to load extension.

class MyExtension < Discorb::Extension
  event :message do |message|
    # ...
  end
end

client.load_extension(MyExtension)

Access Client from extension

You can access Discorb::Client from extension with @client.

class MyExtension < Discorb::Extension
  event :standby do |message|
    puts "Logged in as #{@client.user}"
  end
end

Receiving Arguments on load

You can receive arguments by adding some arguments to #initialize.

class MyExtension < Discorb::Extension
  def initialize(client, arg1, arg2)
    super(client)
    # @client = client will also work, but it's not recommended.
    @arg1 = arg1
    @arg2 = arg2
  end
end

client.load_extension(MyExtension, "arg1", "arg2")

Do something on load

You can do something on load by overriding .loaded. Client and arguments will be passed to it.

class MyExtension < Discorb::Extension
  def self.loaded(client)
    puts "This extension is loaded to #{client}"
  end
end
