Compacting
by celeste
Compacting, a Fabric client mod, merges repeated chat messages into a single line with a counter showing how many times the message arrived.
What it does
Instead of filling the chat with dozens of identical lines, the mod groups them into one message and shows a count of repetitions. Each line is judged by when it was last seen, rather than by scanning neighboring chat lines. Dividers sent across several chat messages, such as those used by some servers, are recognized and handled correctly.
The mod takes its approach from a well-known compacting feature in another client, and it sets itself apart by how it decides when lines match. When Mod Menu and YetAnotherConfigLib (YACL) are installed, a settings screen opens with options that control when a message gets compacted and an optional setting that removes blank chat lines. Fabric Language Kotlin is required. Mod Menu and YACL are optional. The mod is released under the zlib License and is open source, with public source code and an issue tracker. Builds cover 1.19.4 – 26.3, and the latest Fabric file for 26.3 is 1.1.1+26.2, dated 2026-06-16.
