A problem with a call for an existing function.

Hello everyone. I've got a small problem. An error, that crashes LUA, pointing towards the function non-existence.
But there IS a function, and it loads before it is called. Here is the code, for everything else go to PM

function string:split(sep)
	    local sep, fields = sep or ":", {}
	    local pattern = string.format("([^%s]+)", sep)
	    self:gsub(pattern, function(c) fields[#fields+1] = c end)
	    return fields
end

If, for example, I use:
lua tbl = msg:split(":")
Then there's an error "attempt to call nill"

Thanks in advance.

Split into new topic.

Try declaring it thus instead:

string.split = function(self, sep)

When in use it doesn't work. Plus it's strange. It was all working until today. It just stopped seeing the function.

"Doesn't work" in what way? You should probably post the rest of the code.

Unfortunately a string doesn't reference the string library the way we wish it would. If you add a function to the string library, it doesn't get added to normal strings. You'll have to do string.split(str, "sep") instead of str:split("sep")

I've changed the code a bit, and I could use the Luqyd's method. But it's strange. The function perfectly worked before. The problem is solved, thanks.
