ChaTweaks
by PilkeySEK
ChaTweaks is a Fabric client mod that changes how the chat box handles prefixes, filtering, repeated messages and Morse code.
What it does
Chat lines can be wrapped in a configurable prefix and suffix, and incoming messages can be filtered with regular expressions so that matching lines are hidden. A separate anti-spam option collapses several identical messages into a single line, which keeps a busy channel readable.
Morse code runs in both directions: incoming messages can be decoded, and typed text can be sent as Morse code or translated into it before it is posted. Because some client mods that use dot-commands, such as Meteor Client, expect a different command prefix, the chat prefix can be changed to avoid clashes. Only the client needs ChaTweaks, and the mod requires oωo (owo-lib) to run. It is open source under the MIT License and is published for Fabric across five release versions, 1.21.1 – 1.21.8, with files for 1.21.1, 1.21.3, 1.21.4, 1.21.7 and 1.21.8.
Key features
Chat prefix and suffix
Each outgoing chat line can carry a prefix and a suffix, with the text set in the configuration.
Regex chat filtering
Incoming messages are matched against regular expressions, and lines that match can be hidden from the chat box.
Anti-spam collapse
Repeated identical messages are merged into one line instead of filling the chat history.
Morse code decoding
Messages written in Morse code from other players are turned back into readable text.
Morse code sending
Typed text can be sent as Morse code, or translated into Morse code before it is posted.
