A Discord bot that assigns roles based on the reactions to a particular message, and greets members if mentioned in a message, because why not?
Before using the bot, config.edn file should be created in resources directory and filled in according to the config_template.edn file. To easily fill in the blanks, enable the Discord Developer mode in User settings -> Appearance.
And don't forget to give the bot a role with the right to assign and remove roles!
Right now the bot is configured in such a way, that if a person removes their reaction, they will also lose the corresponding role. If they react more than once, however, without removing any of their previous reactions, they will have all the roles they were assigned.
Ok, have fun, bye!
