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.

# 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.
