Client Functions (Fabric)

This mod allows players with sufficient permissions to execute bundles of commands(functions) on the fly without data packs. The default keybind for opening the GUI is B but you can change it. All functions you execute will be saved in a history. You can browse it in the GUI via the arrow buttons or via CTRL + SCROLL WHEEL. In the config file or the Mod Menu integration you can choose how you want your history to be saved.

Dependencies

This mod requires Fabric API and Cloth Config API. Additionally, you can install Mod Menu if you want more configuration. Alternatively, you can just modify the config file clientfunctions.json5 inside .minecraft/config.
