[Lua] How do I make my own functions from outside a program?

Alright, I want to make my own function thing.
I know how to make a slime.print() etc, but I want it to be in a separate file.

So the function file is:

slime = {
print = function(text, mode)
	   w, h = term.getSize()
	   if mode = "m"
			term.setCursorPos(w - (math.floor(string.len(text)) \ 2), h)
			print (text)
	   elseif mode = "wm" then
			term.setCursorPos(w - (math.floor(string.len(text)) \ 2), h)
			write text
	   else
	   error("Slime Print Function Error: slime.print() Unexpected mode")
	   end
end
}
--[ This will let me do slime.print("hello", "m") to print "hello" in the
middle of the screen. slime.print(bye, "wm") will write "bye" in the middle of the screen. I may also add more things like slime.clear() wich also resets the cursor position.
--]

While my code file will have:

load(functionfile) -- < This is what I need
slime.print("Testing Testing 123!", "m")

Also if you can, please also look at my other VERY IMPORTANT post here <——-
Found out the answer! But pleeeeease look at my other post ——-/\

Any reason you couldn't use os.loadAPI()?

Umm, does that work with any file? Like one I make in a slimeos folder and I put os.loadAPI(slimeos/apis/slimedotfunctions)?
Also I didn't know about the os.loadAPI() either….

Well, the thing he suggests is like this:

File "slime":

print = function(text, mode)
		   w, h = term.getSize()
		   if mode = "m"
				    term.setCursorPos(w - (math.floor(string.len(text))  2), h)
				    print (text)
		   elseif mode = "wm" then
				    term.setCursorPos(w - (math.floor(string.len(text))  2), h)
				    write text
		   else
		   error("Slime Print Function Error: slime.print() Unexpected mode")
		   end
end

File <WhereYouNeedYourFuntion>

os.loadAPI("slime")
slime.print("Trololo","wm")

I hope I helped make you understand.
