Listeners 🔗

Function decorators which ultimately act as listeners to certain events that occur on Discord on a regular basis. Now by default, the bots don’t do this, we have to give them that power, i.e., program them in such manner.

Geralt listens to 4 major types of events:

• Errors
• Messages
• User updation
• Guild joining / leaving

Events 🔗

Messages 🔗

Snipe, highlight all depend on this. Both on_message_edit and on_message_delete are very crucial for these commands.

Apart from this, Geralt converts emoji urls to actual emojis using webhooks. For this, these two events are crucial.

User Updation 🔗

Events like on_user_update is very crucial to log the changes that the user makes to their profile. The entire user-history command depends on this.

Guild Join / Leave 🔗

Geralt also sends a webhook to when it joins and leaves a guild. This is done using on_guild_join and on_guild_leave.

Error Handler 🔗

To send logs when you screw up the development process of Geralt, discord.py has a listener called on_command_error. I’ve set it in such a way that a webhook sends a file containing the traceback.
