How to test Lua code fast?


I want to test some lua code fast, so how do I do that without exiting anything?
Let’s say I want to change something on a DarkRP Job (Example).
I want to set the salary to 50 instead of 45, but how do these changes take effect without restarting the server?
I’ve seen it before, where a guy was modifying his chat box without shutting down the server.

Autorefresh. It (currently) does not work on Linux. It should be enabled by default.

Will it also work in singleplayer?

It should. If it doesn’t, I know it works on a listen server (just change “Singleplayer” to “x slots”).

Okay, ill just give it a try, thanks bro!
