Saving functions in files saveFunction(f,file) & loadFunction(file)

[Mock]

In this function i used string.dump
better you know it:

string.dump (function)

Returns a string containing a binary representation of the given function, so that a later loadstring on this string returns a copy of the function. function must be a [B]Lua function [COLOR="Red"]without upvalues.[/COLOR][/B]

You can save functions only from the scripts, (functions inside functions.lua etc) youy cannot save functions like: print, pcall, dofile, doPlayerSay...

function saveFunction(f,file)
	local fufu,ok = pcall(string.dump,f)
	if not fufu then
		return false
	end
	local i = io.open(file,'wb')
	i:write(ok)
	i:close()
	return true
end
function loadFunction(file)
	local q = io.open(file,'rb')
	local a = q:read(-1)
	q:close()
	return  loadstring(a)
end

Example:

function func(...)
	print('print plx',...)
end
saveFunction(func,'func')
local f = loadFunction('func')
f('ok')

And it will print:
print plx ok
