ConfigLib TXF
by jahirtrap
ConfigLib TXF gives mod authors a config library with a generated config screen, JSON5 files, live editing and server sync.
What it does
ConfigLib TXF is a config library for other Minecraft mods. Its main feature is an automatic config screen with tabs, categories, a reset button and fields, built from the config definitions a mod provides. Config files use JSON5, and each value is written with a generated comment that shows its default, range and allowed values, so players can edit them by hand.
Rich widgets cover toggles, sliders, cycle buttons, a color picker, a file and directory chooser, and item or block icon previews. Changes apply instantly while editing, and each field is validated against min, max or regex rules with visual feedback. A mod's settings can be split across several files, with a hub screen that moves between them. Labels, tooltips, tabs and enum values are translated through the standard language files.
The library runs on client and server. Selected fields can be synced from the server to clients in multiplayer so gameplay stays consistent. Mod Menu is optional. Builds exist for Fabric, Forge, NeoForge and Quilt across 10 release versions, 1.20 – 26.3, and the code is open source under the MIT License.
