discordrb

An implementation of the Discord API using Ruby.

Quick links to sections

See also: Documentation, Tutorials

Dependencies

  • Ruby 2.1+
  • An installed build system for native extensions (on Windows, try the DevKit; installation instructions here - you only need to do the quick start)

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

Linux

On Linux, it should be as simple as running:

gem install discordrb

Windows

On Windows, to install discordrb, run this in a shell (make sure you have the DevKit installed! See the Dependencies section):

gem install discordrb --platform=ruby

Run the ping example to verify that the installation works (make sure to replace the username and password in there with your own or your bots'!):

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. 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
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>', client_id: 168123456789123456

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

bot.run

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

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/0SBTUU1wZTWfFQL2

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.
