Fokuso
by Qaz
Fokuso is a client-side Fabric mod that hides chat messages matching filter lists loaded from the config folder, aimed at chat spam from third-party servers.
What it does
Filters are plain files that contain regex patterns. The mod loads every filter list found in the config folder, reports how many lists and filters are enabled, and lets a player switch individual lists on or off without restarting the game. Matching messages are removed from the chat window on the client.
The mod was built as a simple tool for hiding chat messages, mainly to clear out spam sent on third-party servers. Modpack creators can ship their own filter lists, and the source is available if someone wants to change how matching works or add a custom ChatFilter implementation. Fokuso requires Fabric API. Players add it to their own game, and a server needs no copy. It is published for Fabric across seven release versions, and the latest file is 1.2.0 for 1.20.1, released 2023-08-03. The code is open source under the GNU Lesser General Public License v3.0 only.
Key features
Configurable chat filtering
Chat messages are checked against the loaded filters and matches are hidden before they reach the screen.
Regex filter files
Each filter list is a file of regular expression patterns, so one list can cover many variations of the same spam.
Per-list toggles
Individual filter lists can be enabled or disabled, letting a player keep some filters and drop others.
Custom ChatFilter implementations
Developers can implement ChatFilter with their own logic and add it alongside the regex-based lists.
