Fokuso

A Fabric Minecraft (1.20.1) mod for client-side chat filtering using a filter list system to remove spam in chat which is sent on third party servers. You can add filters with files containing regex patterns, or even implement a ChatFilter with your own code.

Commands

/chatfilters list

Lists all currently loaded filter lists and how many of their filters are enabled.

/chatfilters reload

Loads filter lists from config folder

/chatfilters toggle <list> <enabled>

Enable or disable a specific filter list.

Regex filter list files

Filter lists can be added by adding files to the fokuso config folder with the .filters file extension. Each line is a different regex pattern. Empty lines and comments (lines starting with #) are ignored. It's possible to use several shortcuts in the regex filters, e.g. \u for usernames.

You can test the pattern using a tool like regex101.com.

# Simple filter to remove all messages regarding achieved achievements.
\u has made the advancement \[.*?]

If you create any filter lists that might be useful to others, please share them, so that they can be added to this page.

Usage

This is intended as a simple tool to hide chat messages when it's not possible or desirable to alter the source. It's primarily intended to be used to remove chat spam on third party servers but can also be used by modpack creators to remove chat spam from other mods.
