Mod Required
by ChuAn
Mod Required is a NeoForge utility that exports the dependency map of a modpack as HTML, JSON, DOT and summary text files.
What it does
A modpack often contains library mods that several other mods rely on, and a plain mod list does not show which mod needs which. Mod Required builds a structured dependency map of the installed mods instead. A simple in-game command generates reports for the current modpack, so pack makers, developers and players can inspect how mods depend on each other in a readable way.
The exporter writes its files into a moddeps-export folder. The HTML report opens in a browser and comes in English and Simplified Chinese layouts, and it defines the dependency types used in the report, Required, Optional, Incompatible and Discouraged. Files are available for NeoForge on 1.21.1 only, with version 1.0.0 as the current build, released under All rights reserved and not open source. The mod can run on a client, a server or both, and it is optional on either side.
