Help with string manipulation?
I'm pretty sure this involves string patterns, but I'm finding a way to get a group of characters in between two defined strings. For example,
string = "apple orange banana watermelon"
The two defined strings could be "apple" and "banana", so the text in between is " orange ", and that's what it would print.
Is there something like that I can do? Thanks.

Use string.sub. hiimgoodpack 2009 — 6y

local s = "apple orange banana watermelon" print(string.match(s, "apple(.*)banana")) -- prints " orange "
The pattern string, "apple(.*)banana" captures any string (.*) between apple and banana. string.match will then return this capture.

You really should be explaining how this pattern works. User#5423 17 — 6y

Did I not explain it enough? Should I make it explicit that (.*) captures zero or more of any character? There really isn't a a whole lot of stuff going on in this relatively simple regex. XAXA 1569 — 6y
