Algrim Chat
by Algrim-MC
Algrim Chat restyles incoming chat messages on the client, using patterns that match server messages and apply custom styling to them.
What it does
Each pattern has three parts: a literal part that matches characters exactly, a regex part marked at its beginning and end, and a style part that applies formatting to the matched message. Literal parts are the simplest to write, and some special characters are read as other pattern parts, so escaping is avoided where possible. The style parts are finally split into two sections.
Overrides are defined by name and can add or remove styles, so one entry can take bold away from a matched message. A prefix such as the word bold with a leading mark removes that style. The config GUI opens with the R and C keys by default. Algrim Chat is client-side only, so servers run without it and players install it alone.
The mod is open source under the GNU Lesser General Public License v3.0 only, with a source code repository and an issue tracker. It requires Fabric Language Kotlin and MaLiLib, which are listed with each release. Fabric files cover 1.20.1 – 1.21.10 across 13 release versions, and the latest file is 2.0.0+1.21.8 for 1.21.10, published 2025-10-10 on the beta channel.
Key features
Server message patterns
Patterns match server messages and style them, so styling follows the text the server sends.
Literal and regex parts
A pattern combines exact literal text with regex segments for matching varying content.
Style overrides
Override definitions can be applied or removed by name, using a list of styles.
Style removal
A prefix in an override removes a style, so bold text can be turned back to plain.
Config GUI shortcut
The configuration screen opens with the R and C keys by default.
