In a nutshell, discord bot to register channels, and periodically delete messages older than x (configurable) days on them with the optional capability to archive deleted message for up to x (configurable) days in case a useful message is delete

• [ ] docker-compose to run postgres db
• [ ] db connection + setup on postgres with seaorm
• [ ] discord connection with poise (ping command)
• [ ] ping command
• [ ] moldy table -> id, guild_id, server_id, message_ttl (usize in days), enabled (bool) (+later admin things -> created_by, created_at)
• [ ] /devour #channel <ttl> command to setup message periodic deletion on a chanel
• [ ] /nodevour #channel to pause
• [ ] setup parallel tokio task that periodically checks for old messages in registered channels, delete them if any
• [ ] add -> archive db table to remember messages (guild_id,channel_id,content,author) for a time (opt in)
• [ ] /devoured <since> <up_to> -> list timestamp / owner / short text of some messages
• [ ] /regurgitate (<id>)|(<since>/<up_to>) (or maybe two commands)

@obayemi lemme try with the docker-compose one first. Should I use master or the feature branch?

There is nothing merged to master yet
