=> ↺ From Lua to JSON: refactoring WirePlumber's configuration system
Refactoring WirePlumber's configuration system is the first big feature I took up since I joined the PipeWire/WirePlumber team a year back. It's a year well spent in my professional life, hanging around with caring people and truly open source technology. With what I have seen in the multimedia stacks, I honestly believe PipeWire is the next generation multimedia server and WirePlumber playing the role of enhancing its utility and appeal.
Let me cut back to the subject at hand.
=> ↺ Trick Lua into becoming an object-oriented language | Opensource.com
Lua isn't an object-oriented programming language, but a scripting language utilizing C functions and a C-like syntax. However, there's a cool hack you can use within Lua code to make Lua act like an object-oriented language when you need it to be. The key is in the Lua table construct, and this article demonstrates how to use a Lua table as a stand-in for an object-oriented class.

The term "object-oriented" is a fancy way of describing, essentially, a templating system. Imagine you're programming an application to help users spot and log zombies during a zombie apocalypse. You're using an object-oriented language like C++, Java, or Python. You need to create code objects that represent different types of zombies so the user can drag them around and arrange them on a map of the city. Of course a zombie can be any number of things: dormant, slow, fast, hungry, ravenous, and so on. That's just textual data, which computers are good at tracking, and based on that data you could even assign the virtual "object" a graphic so your user can identify which general type of zombie each widget represents.
