Is there any way to make a pattern that expects 0 or more characters? "%a+" accepts 1+, "%a?" accepts 0 or 1. Would I simply combine the two ("%a?+" or "%a+?")? Or would I simply have to make an extra elseif statement?

if you read this link, you'll find that - and * are both 0 or more repetitions, so it would be "%a*" or "%a-"

Thanks... I didn't remember that for some reason. probably because it was around 2 A.M. when I was reading it.

You can use "or" in patterns? O.o

No. In regexes you can do things like "(A|B)" which means "match the letter A or B" but there's nothing like it in Lua patterns sadly.

Yes, that's what I thought... The OP used an "or" operand in their capture, so I wasn't sure.

As far as I know you could just use (for an or) "[AB]" which would result in searching for A or B.

yea but thats on character level - you cant code it to look for "cat" or "dog"

I was simply stating two different ways of doing what I thought might work...
%a+? and %a?+

my logic:
%a+? would check for multiple characters, but they can be none because the entire statement has ? after it
%a?+ checks for one or more "maybe" space characters
