command on join
by j0hn_0
command on join runs server commands for each player when they connect, grouped by name, for Fabric servers running 26.2.
What it does
When a player joins, the server runs a list of commands set up in the mod's configuration. Commands are organized into groups, and a player's name decides which group applies. Within a line, the placeholder player% is replaced with the name of the joining player before the command runs. Groups are checked in the order they are listed, and the first matching group wins, so specific names should appear before general fallbacks. Players not named in any group fall back to the default GROUP, which can hold its own commands.
The mod is server-side only, so players join without installing it. It is published for Fabric and 26.2 only, with a 1.0.0 build dated 2026-07-01. Its license is All rights reserved, so the code is not open source.
