nosedrum

nosedrum is a command framework for use with the excellent nostrum library.

It contains behaviour specifications for easily implementing command handling for both Discord's application commands and the traditional text-based commands in your bot along with other conveniences to ease creating an interactive bot.

nosedrums provided implementations are largely based off what was originally written for bolt. bolt also contains around 57 commands based off the Nosedrum.Command behaviour that you can explore if you're looking for inspiration.

The application command related parts of the framework consist of two parts:

• Nosedrum.ApplicationCommand, the behaviour that all application commands must implement.
• Nosedrum.Invoker, the behaviour for any slash command invoker. A default implementation provided by nosedrum resides at Nosedrum.Invoker.Dispatcher.

The traditional command processing related parts of the framework consists of three parts:

• Nosedrum.Command, the behaviour that all commands must implement.
• Nosedrum.Invoker, the behaviour of command processors. Command processors take a message, look it up in the provided storage implementation, and invoke commands as required. nosedrum ships with an implementation of this based on bolt's original command parser named Nosedrum.Invoker.Split.
• Nosedrum.Storage, the behaviour of command storages. Command storages allow for fast and simple lookups of commands and command groups and store command names along with their corresponding Nosedrum.Command implementations internally. An ETS-based command storage implementation is provided with Nosedrum.Storage.ETS.

Additionally, the following utilities are provided:

• Nosedrum.Converters, functions for converting parts of messages to objects from Nostrum such as channels, members, and roles.
• Nosedrum.MessageCache, a behaviour for defining message caches, along with an ETS-based and an Agent-based implementation.

nosedrums provided implementations are largely based off what was originally written for bolt. bolt also contains around 59 commands based off the Nosedrum.Command behaviour that you can explore if you're looking for inspiration.

Installation

Simply add :nosedrum to your mix.exs:

def deps do
  [
    {:nosedrum, "~> 0.4"},
  ]
end

If you want to install the GitHub version of Nostrum, you will need to specify it with override: true in your mix.exs, for example:

def deps do
  [
    {:nosedrum, "~> 0.4"},
    {:nostrum, github: "Kraigie/nostrum", override: true}
  ]
end
