Comment on Where can I find tutorials on embedding Lua scripting into applications

What do you mean “embedding lua into applications”?
I assume you mean you want an application extensible by user lua script?
You build an API that calls the lua interpreter and passes the script, and reads the output; same as you would for any other scripting language. You define what the inputs should be, create the interface for executing the user defined script through shell commands, and then retrieve the output.
For python you’re going to probably use this:
docs.python.org/3/library/subprocess.html#subproc…
For C# you’re going to use Process

The complexities arise in your implementation and there’s no single guide.

While lua ships a standalone interpreter, it is very much designed to be embedded directly into an application. This is done by invoking some C apis to load the interpreter into the application’s memory space. OP wants to do that rather than invoking another process and reading the output. When embedding into a host, the host can provide its own objects to be manipulated by the user script allowing for a much better extensibility experience.

That solution is janky and slow as hell. I'd rather just embed it into my own software, which is mostly done, except it doesn't find functions as functions, but as nil value.
