lachsbot

JVM Discord Bot used to log all the things, and offer utility commands.

Designed for personal use, though you're most welcome to use lachsbot within the bounds of its License.

Features

Logging

The bot logs a handful of events, hopefully more over time. Messages received, updated, and deleted, members banned or unbanned from guilds, and members joining/leaving guilds are some example events that are logged in detail by lachsbot.

There are cases where Discord's API does not provide very useful information in logs, especially for the message deleted event, where it only provides us with the ID of the message that was deleted. By storing received and updated messages in MongoDB, lachsbot will try to piece together what the last known content of the deleted message was, making it far easier for moderators to check for rulebreakers abusing message deletion.

Slash Commands

Some slash commands are provided, such as:

1. /purge (Moderators Only)

   This will clear the 10 most recent messages sent in the channel the command is ran.

2. /shutdown (Admins Only)

   This softly shuts down the bot, just as a killswitch in case it goes rogue. ;)

CLI

lachsbot features a basic CLI system allowing for administrative control over the bot. The following CLI commands are provided:

1. exit

   Softly shuts down the bot.

2. help

   View a list of available commands within the CLI. The information it provides is automatically populated, and paginated.

3. reload

   Soft-reload functionality, mostly just to reload the configuration files.

4. status

   Check the status of the bot, such as its JVM uptime.
