Finding a number in a string lua

Question

A simple question.

When a roll has been done it shows as:

"Need Roll - 150 for [SomeItem] by [SomePerson] + role bonus"

I wish for some way to isolate the number 150. However there is no such thing as a split in lua (as far as I know) so what's the best way to accomplish this?

Answer 1

If this is for WoW, check out this strsplit function there.

Otherwise, you can do it with string.find or string.match and patterns. It could be as simple as doing a string.match for %d+ to find the first number in the string, as follows:

number = string.match(
    "Need Roll - 150 for [SomeItem] by [SomePerson] + role bonus",
    "%d+"
)

If you use string.match instead of string.find you won't need to discard the first two results. Parents around ´%d+´ are not needed in any case. You might have to call tonumber in the result: number = tonumber(string.match(theString, "%d+")) – Platte

Answer 2

string.match (stringvar, "%d+")
