ULib

ULib, short for Universal Library, is a Lua-based library for Garry's Mod that provides a collection of utilities to support server-side scripting and administration. The library is designed to be included by server scripts to offer common functionality and reduce redundancy.

Core features include a permissions framework with user groups and access levels, a command registration system for chat and console commands, and data storage utilities for player data, settings, and persisted state. It also offers networking helpers, timers, hooks, and general Lua utilities that are frequently used by server scripts.

ULib is commonly used in conjunction with ULX, the Admin Mod for Garry's Mod. ULX relies on ULib for its underlying functionality, and the two are often deployed together on public servers to provide a complete admin toolkit. The library is modular, allowing developers to load only the parts they need.

Development and license: ULib is an open-source project maintained by contributors from the Garry's Mod community. Since its early versions, it has received updates and patches to improve compatibility with Garry's Mod updates and Lua changes. The project is hosted on public repositories and documented for users and developers.
