Regex alternatives?

[v6o]

Edit: I understand now that the topic title is a bit misleading. I meant "Alterations"


Does WoW not support alterations ?
e.g. "start (part1|part2|part3) end"


Edit: When I'm already asking, what would be the option to match nothing or a string
e.g. "start end" or "start middle end"

Tested it in my interactive lua-console and you're right - it seems like Lua doesn't understand alternations, it ignores the vertical bar | and sees it as part of the normal characters.

"^start (.*) end$" would be a very universal regex which would fetch all things in between, this would output:
"start end" -> nil
"start middle end" -> "middle"

But maye you should specialize it a bit more to fit your case.
