fabric Force Lowercase
Fabric Force Lowercase makes the first word of a typed chat command lowercase before the command is sent, which helps avoid syntax errors in case-sensitive commands.
What it does
When a player types a command starting with a slash in chat, the first argument is converted to lowercase before the message leaves the client. This keeps commands that expect lowercase input from failing on mixed-case typing. The mod runs on the client alone, so players install it and servers do not need it. It is published for Fabric only, across 21 release versions 1.19.4 – 26.3, and is open source under the MIT License.
Key features
Lowercase first argument
The first argument of a chat command is forced to lowercase as it is typed, before it is sent.
Fewer syntax errors
Commands that only accept lowercase input no longer break when a player types capital letters by habit.
Chat-only effect
Only the typed command is changed, and ordinary chat messages keep their original capitalization.
