Using Lua along with C?

Question

C++ / C#

Hello! Is it possible to somehow merge the Lua language with the C language? I haven't heard of it, but for C++ along with Lua to hear, it's used in Roblox if I'm not mistaken.

And so ... if you still can, Lua is still suitable for games. If you use Lua code in C, what is it possible to make:
Game, Software or something else?

I will be glad to all answers! ;)

Answer 1

you take luajit and call it from sish code.

The other way around is also possible, for this there is an ffi package in luajit

what is possible to do:
Game, Software or something else?

Whatever you want, then do it. For example, Tarantool and Redis use luajit for stored procedures

It's not entirely clear what exactly you mean by join.
For example, we included Lua's external script interpreter in the C++ program : https://rlab.ru/tools/rtester.html
This is a fully working project, we continue to develop and refine it. So it doesn't have to be just games.
