How To Install lua-cqueues on Rocky Linux 8
Introduction
In this tutorial we learn how to install lua-cqueues on Rocky Linux 8.
What is lua-cqueues
cqueues is a type of event loop for Lua. It doesn’t use callbacks but instead you communicate with an event controller by the yielding and resumption of Lua coroutines using objects. cqueues are stackable. Each instantiated cqueue is a poll-able object which can be polled from another cqueue, or another event loop system entirely. The design is meant to be non-intrusive, composable, and embeddable within existing applications. cqueues includes a sockets library with DNS, buffering, end-of-line translation, SSL/TLS, and descriptor passing support builtin. Domain querying, connection establishment, and SSL negotiation are handled transparently as part of a state machine entered with every I/O operation, so users can read and write immediately upon instantiating the object, as if opening a regular file. cqueues also includes modules for handling signals, threads, and file change notifications using native kernel facilities and accessible through easy to use interfaces which abstract the different kernel facilities.
