Constructor Details

#initialize(log_mode: :normal, token: nil, client_id: nil, type: nil, name: '', fancy_log: false, suppress_ready: false, parse_self: false, shard_id: nil, num_shards: nil, redact_token: true, ignore_bots: false, compress_mode: :large) ⇒ Bot

Makes a new bot with the given authentication data. It will be ready to be added event handlers to and can eventually be run with #run.

As support for logging in using username and password has been removed in version 3.0.0, only a token login is possible. Be sure to specify the type parameter as :user if you're logging in as a user.

Simply creating a bot won't be enough to start sending messages etc. with, only a limited set of methods can be used after logging in. If you want to do something when the bot has connected successfully, either do it in the EventContainer#ready event, or use the #run method with the :async parameter and do the processing after that.

Parameters:

  • log_mode (Symbol) (defaults to: :normal) —

    The mode this bot should use for logging. See Logger#mode= for a list of modes.

  • token (String) (defaults to: nil) —

    The token that should be used to log in. If your bot is a bot account, you have to specify this. If you're logging in as a user, make sure to also set the account type to :user so discordrb doesn't think you're trying to log in as a bot.

  • client_id (Integer) (defaults to: nil) —

    If you're logging in as a bot, the bot's client ID. This is optional, and may be fetched from the API by calling #bot_application (see Application).

  • type (Symbol) (defaults to: nil) —

    This parameter lets you manually overwrite the account type. This needs to be set when logging in as a user, otherwise discordrb will treat you as a bot account. Valid values are :user and :bot.

  • name (String) (defaults to: '') —

    Your bot's name. This will be sent to Discord with any API requests, who will use this to trace the source of excessive API requests; it's recommended to set this to something if you make bots that many people will host on their servers separately.

  • fancy_log (true, false) (defaults to: false) —

    Whether the output log should be made extra fancy using ANSI escape codes. (Your terminal may not support this.)

  • suppress_ready (true, false) (defaults to: false) —

    Whether the READY packet should be exempt from being printed to console. Useful for very large bots running in debug or verbose log_mode.

  • parse_self (true, false) (defaults to: false) —

    Whether the bot should react on its own messages. It's best to turn this off unless you really need this so you don't inadvertently create infinite loops.

  • shard_id (Integer) (defaults to: nil) —

    The number of the shard this bot should handle. See https://github.com/discordapp/discord-api-docs/issues/17 for how to do sharding.

  • num_shards (Integer) (defaults to: nil) —

    The total number of shards that should be running. See https://github.com/discordapp/discord-api-docs/issues/17 for how to do sharding.

  • redact_token (true, false) (defaults to: true) —

    Whether the bot should redact the token in logs. Default is true.

  • ignore_bots (true, false) (defaults to: false) —

    Whether the bot should ignore bot accounts or not. Default is false.

  • compress_mode (:none, :large, :stream) (defaults to: :large) —

    Sets which compression mode should be used when connecting to Discord's gateway. :none will request that no payloads are received compressed (not recommended for production bots). :large will request that large payloads are received compressed. :stream will request that all data be received in a continuous compressed stream.

#create_server(name, region = :'eu-central') ⇒ Server

Discord's API doesn't directly return the server when creating it, so this method waits until the data has been received via the websocket. This may make the execution take a while.

Creates a server on Discord with a specified name and a region.

Parameters:

  • name (String) —

    The name the new server should have. Doesn't have to be alphanumeric.

  • region (Symbol) (defaults to: :'eu-central') —

#profile ⇒ Profile Also known as: bot_user

The bot's user profile. This special user object can be used to edit user data like the current username (see Profile#username=).

Returns:

  • (Profile) —

    The bot's profile that can be used to edit data.

#run(background = false) ⇒ Object

Note:

Running the bot in the background means that you can call some methods that require a gateway connection before that connection is established. In most cases an exception will be raised if you try to do this. If you need a way to safely run code after the bot is fully connected, use a EventContainer#ready event handler instead.

Runs the bot, which logs into Discord and connects the WebSocket. This prevents all further execution unless it is executed with backround = true.

Parameters:

  • background (true, false) (defaults to: false) —

    If it is true, then the bot will run in another thread to allow further execution. If it is false, this method will block until #stop is called. If the bot is run with true, make sure to eventually call #join so the script doesn't stop prematurely.

#send_file(channel, file, caption: nil, tts: false, filename: nil, spoiler: nil) ⇒ Object

Note:

This executes in a blocking way, so if you're sending long files, be wary of delays.

Sends a file to a channel. If it is an image, it will automatically be embedded.

Examples:

Send a file from disk

bot.send_file(83281822225530880, File.open('rubytaco.png', 'r'))

Parameters:

  • channel (Channel, String, Integer) —

    The channel, or its ID, to send something to.

  • file (File) —

    The file that should be sent.

  • caption (string) (defaults to: nil) —

    The caption for the file.

  • tts (true, false) (defaults to: false) —

    Whether or not this file's caption should be sent using Discord text-to-speech.

  • filename (String) (defaults to: nil) —

    Overrides the filename of the uploaded file

  • spoiler (true, false) (defaults to: nil) —

    Whether or not this file should appear as a spoiler.

#stop(_no_sync = nil) ⇒ Object

Note:

#voice_connect(chan, encrypted = true) ⇒ Voice::VoiceBot

Connects to a voice channel, initializes network connections and returns the Voice::VoiceBot over which audio data can then be sent. After connecting, the bot can also be accessed using #voice. If the bot is already connected to voice, the existing connection will be terminated - you don't have to call Voice::VoiceBot#destroy before calling this method.

Parameters:

  • chan (Channel, String, Integer) —

    The voice channel, or its ID, to connect to.

  • encrypted (true, false) (defaults to: true) —

    Whether voice communication should be encrypted using (uses an XSalsa20 stream cipher for encryption and Poly1305 for authentication)

Returns:

  • (Voice::VoiceBot) —

    the initialized bot over which audio data can then be sent.

Raises:

  • (ArgumentError)

#voice_destroy(server, destroy_vws = true) ⇒ Object

Disconnects the client from a specific voice connection given the server ID. Usually it's more convenient to use Voice::VoiceBot#destroy rather than this.

    The server, or server ID, the voice connection is on.

  • destroy_vws (true, false) (defaults to: true) —

    Whether or not the VWS should also be destroyed. If you're calling this method directly, you should leave it as true.
