An implementation of the Discord API using Ruby.
Quick links to sections
- Ruby 2.1+
- 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.
This section only applies to you if you want to use voice functionality.
- 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.
Using Bundler, you can add discordrb to your Gemfile:
And then install via
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
Alternatively, while Bundler is the recommended option, you can also install discordrb without it.
Linux / macOS
gem install discordrb
Make sure you have the DevKit installed! See the Dependencies section)
gem install discordrb --platform=ruby
To run the bot:
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:
Select option 3, and then run
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:
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:
You can make a simple bot like this:
require 'discordrb' bot = ::. token: '<token here>' bot.(with_text: 'Ping!') do |event| event.respond 'Pong!' end bot.run
This bot responds to every "Ping!" with a "Pong!".
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!
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
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.
