WHY THIS FORK?

I have conflicts with other gems which have hard requirements of rest-client 2.0
discordrb is hardcoded to use rest-client >= 2.1.0.rc1.
This fork relaxes discordrb's dependency of rest-api.

discordrb

An implementation of the Discord API using Ruby.

See also: Documentation, Tutorials

Dependencies

  • Ruby 2.2+
  • An installed build system for native extensions (on Windows for Ruby < 2.4, try the DevKit; installation instructions here - you only need to do the quick start)

Note: RubyInstaller for Ruby versions 2.4+ will install the DevKit as the last step of the installation.

Voice dependencies

This section only applies to you if you want to use voice functionality.

  • libsodium
  • A compiled libopus distribution for your system, anywhere the script can find it. See here for installation instructions.
  • FFmpeg installed and in your PATH

In addition to this, if you're on Windows and want to use voice functionality, your installed Ruby version needs to be 32 bit, as otherwise Opus won't work.

Installation

With Bundler

Using Bundler, you can add discordrb to your Gemfile:

gem 'discordrb'

And then install via bundle install.

Run the ping example to verify that the installation works (make sure to replace the token and client ID in there with your bots'!):

To run the bot while using bundler:

bundle exec ruby ping.rb

With Gem

Alternatively, while Bundler is the recommended option, you can also install discordrb without it.

Linux / macOS

gem install discordrb

Windows

Make sure you have the DevKit installed! See the Dependencies section)

gem install discordrb --platform=ruby

To run the bot:

ruby ping.rb

Troubleshooting

If you get an error like this when installing the gem:

ERROR:  Error installing discordrb:
        The 'websocket-driver' native gem requires installed build tools.

You're missing the development kit required to build native extensions.

RubyInstaller for ruby 2.4.3-2 and above

RubyInstaller after version 2.3.3 now includes the development kit in the installer. If you do not have the development kit and have installed ruby using RubyInstaller, open a command prompt with administrator privileges and run:

ridk install

Select option 3, and then run

ridk enable

To enable the changes

RubyInstaller for ruby 2.3.3 and below

Download the development kit here (scroll down to "Development Kit", then choose the one for Ruby 2.0 and your system architecture) and extract it somewhere. Open a command prompt in that folder and run:

ruby dk.rb init
ruby dk.rb install

Then reinstall discordrb:

gem uninstall discordrb
bundle install

# Or, if you didn't use bundler:
gem install discordrb

If Ruby complains about ffi_c not being able to be found:

For example

C:/Ruby23-x64/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- ffi_c (LoadError)

Your ffi setup is screwed up, first run gem uninstall ffi (uninstall all versions if it asks you, say yes to any unmet dependencies), then run gem install ffi --platform=ruby to fix it. If it says something about build tools, follow the steps in the first troubleshooting section.

If you're having trouble getting voice playback to work:

Look here: https://github.com/meew0/discordrb/wiki/Voice-sending#troubleshooting

Usage

You can make a simple bot like this:

require 'discordrb'

bot = Discordrb::Bot.new token: '<token here>'

bot.message(with_text: 'Ping!') do |event|
  event.respond 'Pong!'
end

bot.run

This bot responds to every "Ping!" with a "Pong!".

See additional examples here.

You can find examples of projects that use discordrb by searching for the discordrb topic on GitHub.

If you've made an open source project on GitHub that uses discordrb, consider adding the discordrb topic to your repo!

Webhooks Client

Also included is a webhooks client, which can be used as a separate gem discordrb-webhooks. This special client can be used to form requests to Discord webhook URLs in a high-level manner.

Usage

require 'discordrb/webhooks'

WEBHOOK_URL = 'https://discordapp.com/api/webhooks/424070213278105610/yByxDncRvHi02mhKQheviQI2erKkfRRwFcEp0MMBfib1ds6ZHN13xhPZNS2-fJo_ApSw'.freeze

client = Discordrb::Webhooks::Client.new(url: WEBHOOK_URL)
client.execute do |builder|
  builder.content = 'Hello world!'
  builder.add_embed do |embed|
    embed.title = 'Embed title'
    embed.description = 'Embed description'
    embed.timestamp = Time.now
  end
end

Note: The discordrb gem relies on discordrb-webhooks. If you already have discordrb installed, require 'discordrb/webhooks' will include all of the Webhooks features as well.

Support

You can find me (@meew0, ID 66237334693085184) on the unofficial Discord API server - if you have a question, just ask there, I or somebody else will probably answer you: https://discord.gg/3Trm6FW

Development

This section is for developing discordrb itself! If you just want to make a bot, see the Installation section.

After checking out the repo, run bin/setup to install dependencies. You can then run tests via bundle exec rspec spec. Make sure to run rubocop also: bundle exec rubocop. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
