Discord Bot for use in the Relay channel. Makes use of elizabot.js to have natural language conversations and fetches data from Roberts Space Industries for Star Citizen funding, citizens and UEE commands.
In order to use this you'll need at least NodeJS v6.0.0 installed. It helps to have Git to clone the repository. You should copy the configuration from config/default.yaml to config/local.yaml and configure as necessary.
$ git clone https://gitlab.com/Relay_SC/relay-bot.git
$ cd relay-bot
$ cp config/default.yaml config/local.yaml
$ npm install
$ export RELAYBOT_DISCORD_BOTUSER_TOKEN=<bot_token>
$ export RELAYBOT_DISCORD_CLIENTID=<app_id>
$ node run.js
Replace <bot_token> with your Bot User Token and <app_id> with the Client ID from Discord Developer. If you want these environment variables to persist between sessions then I recommend that you add these lines to your ~/.bashrc.
It is recommended that you also view the Setting up Google Calendar Integration section so that commands that rely on that functionality work.
You can use the url below, replacing <app_id> with the Client ID from the Developer page, to add it to a server you have 'Manage Server' permissions on.
https://discordapp.com/oauth2/authorize?&client_id=<app_id>&scope=bot
You can then use the !invite command to get this URL in future.
relay-bot is configured in two ways - environment variables for sensitive information and a configuration file for everything else. relay-bot ships with a config/default.yaml configuration file, this should be copied and modified to the user's liking then saved as config/local.yaml. Check out the Deploying section for the recommended method of dealing with Environment Variables in production - for development, however, we recommend writing a small bash script in .env.sh with the Environment Variables.
There are lots of configuration options available and custom commands can add their own configuration options - some options are explained below.
At the top of the configuration file, you can configure the identity of the bot - so you don't have to change any code to use this bot elsewhere.
bot:
name: RelayBot
avatarPath: ./assets/bot-avatar.jpg
gameName: testing
description: >
I'm RelayBot, a Rogerian psychotherapist hired by the
The Relay. You can chat for a therapy session
or tell me some commands. I'm an open source
psychotherapist too, check my source out here:
https://gitlab.com/imperialnewsnetwork/relay-bot.
To find the commands I can run, type !help.
repositoryUrl: https://gitlab.com/imperialnewsnetwork/relay-botCommands can be individually disabled by adding them to the commands.disabled property in the configuration file.
commands:
disabled:
- echoIf you don't want any of the commands from any of the sources, then you can remove that source entirely.
Commands can be aliased by adding the command to be aliased to the configuration file and then a list of the aliases.
commands:
aliases:
about:
- info
stats:
- funds
- citizens
- uee
issue:
- bug
thebase:
- baseradioHere we can see an example where about is aliased as info; stats is aliased as funds, citizens and uee, issue is aliased as bug and thebase is aliased as baseradio. Aliases apply to repository commands.
Since relay-bot v2.0.0, there is a command system in place that allows the bot to be extended easily without modifying the core bot.
It's easy to create a new command, make a file anywhere - as long as the relay-bot system user has privileges - and then create a command that looks something like the one below. You should add this to the commands.sources property in the configuration file.
You'll need to update the relative path to the command module.
'use strict';
const Command = require('../command'); // update this path
class YouTubeCommand extends Command {
constructor() {
super({
command: 'rsiyt',
description: 'Subscribe to Star Citizen on YouTube!',
hidden: false
});
}
respond(message, bot, config, resolve, reject) {
resolve('You can find and subscribe to Star Citizen on YouTube here: ' +
'https://www.youtube.com/user/RobertsSpaceInd');
}
}
module.exports = [YouTubeCommand];It's really easy to create a command. Every command needs a call to the constructor with it's name, description and if it's hidden - all of these are used in the !help command. After that, there are two main functions that you'll be able to override in order to create a new unique command - isEligible(message, bot, config) and respond(message, bot, config, resolve, reject).
isEligible is used to check if a command is eligible for being run, in the majority of cases you won't need to override this, by default it'll match your command and check if it's been disabled or aliased in the configuration too.
If you do override this then you should make sure that your command respects the disabled commands and aliases in the configuration.
This function takes three parameters, message, bot and config. Both message and bot are from Discordie - the library we use for interfacing with Discord - you can find the documentation for message here and you can find the documentation for bot here - this is the User that the bot is currently running as, so you can find the bot id and name. config is the node-config instance that is used for configuration. You can check for your own configuration options in there.
respond is called if your command is found to be eligible to respond. message, bot and config are the same as in isEligible. resolve and reject are callbacks that should be used to return a message to be sent and to return a error, respectively.
You should check out the commands that ship with the bot to see examples of this being used.
Once installed, the list of available commands can be viewed with !help [page number].
Since v2.0.0, Command Repositories have been introduced. You can add a repository by adding the following to your configuration:
repository:
sources:
- url
blacklist:
- list of command namesrelay-bot's RepositoryCommand will load the commands and responses found at the given url and use them. The endpoint should be in the format as follows:
[
{
"command": "command name",
"description": "help text",
"hidden": false,
"response": "what I should respond with"
},
...
]All commands can be aliased and disabled like regular commands in the configuration.
You can specify a blacklist of commands that will not be used if they conflict with names that the regular bot commands use (you wouldn't be able to use disable for this because that would disable the regular command).
Get in touch if you'd like your command repository to be listed here.
The copy command is a meta-command that can be configured to copy all messages from one channel on a guild to another channel (on the same guild or another guild). It can be configured as so:
copy:
- fromChannel: 'from_channel'
toChannel: 'to_channel'You should replace the from_channel and to_channel parts with the IDs of the channels that you wish to use - you can get the channel IDs using the !debug command.
You can have all instances of the bot deleting it's response to a user for a given guild logged to a specific channel. This is useful for moderation purposes. Just add the following to the configuration.
commands:
...
deletedMessagesLogging:
- fromGuilds:
- 'guild_id'
toChannel: 'channel_id'
type: responses
include: edits
...Replace guild_id with the ID of a guild - you can specify multiple guilds. Replace channel_id with the ID of a channel. You can specify multiple guilds per output channel and as many pairs of guilds and output channels as you wish. Both the guild and channel IDs can be determined by running the !debug command. You can optionally add the type property set to all which will log all deleted messages in a given guild. You can also optionally add the include property - if set to edits it will also log all edits.
By default, two commands fetch from Google Calendar, you can get an API Key by following these steps:
- Go to Google Developers Console and create a new project for the bot.
- Enable Google Calendar API for that project.
- Create API Credentials for the bot. You can choose any type of key - Server, Browser, Android or iOS - though we chose Server.
- Put the API key you get in the environment variable
DISCORD_GOOGLE_APIKEY.
We'd love any contributions to the code and actively encourage people to fork, make modifications and create pull requests so we can merge any changes we like back into the bot.
Before submitting a pull request, make sure your code doesn't have any issues with the jshint utility.
Keep in mind that any modified versions that are not merged back into this codebase should comply with the GNU Affero General Public License v3.0 that we're using.
When deploying into production, we recommend running on a Linux box and creating a dedicated system user to run the bot. On Ubuntu 15.10, we're using the following systemd unit file:
[Unit]
Description=Relay Discord Bot
After=system.slice multi-user.target
[Service]
Type=simple
User=relay-bot
Group=relay-bot
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=relay-bot
SyslogFacility=local0
EnvironmentFile=/home/relay-bot/relay-bot/.env
WorkingDirectory=/home/relay-bot/relay-bot
ExecStart=/usr/bin/node run.js
Restart=always
[Install]
WantedBy=multi-user.targetWe also create a .env file in the RelayBot folder that contains the configuration Environment Variables:
RELAYBOT_DISCORD_BOTUSER_TOKEN=<bot_token>
RELAYBOT_DISCORD_CLIENTID=<app_id>
RELAYBOT_GOOGLE_APIKEY=<google_api_key>
