I currently have two two triggers doing the work that one should be able to do, the reason for this is items can be represented in my inventory in two different ways, if there is a single of that item, or multiple.

IE:

I don't know if there's a way to make things optional in zscript, if there is, then use that. If no one suggests one, I can give you a REGEX pattern which will match both.

Tell me about these REGEX patterns you keep mentioning.

({~(%d~)|%s}) (*)

While that is all the pattern you really need, you could probably better refine the * with something tighter--depending on what symbolics are allowed to appear in an item name (if it's just letters and spaces, then you could use [%s%w]). In both Zscript and Regex.

REGEX is short for regular expressions. Ultimately, zScript patterns are translated into Regular Expressions for purposes of matching. However, zScript is MUCH simpler than Regular Expressions. Still, Regular Expressions are significantly more powerful and, to my knowledge, can do things which zScript can't do. I've fallen into the habit of using Regular Expressions even when there is a perfectly acceptable zScript pattern, which some frown upon, but there are many scripts that I use which would require Regular Expressions to work.

The REGEX pattern you would want would be:

For the most part, maybe. But I definitely have a number of patterns which would be extremely difficult or impossible with zScript, which is why I stick to REGEX. However, I often shy away from helping out with patterns because I don't often know enough about zScript to say when it's not going to be enough anymore, and I certainly would rather people be able to use something which is far simpler to understand.

Thank you guys for help, I don't know if I am ready to jump into REGEX considering I am still learning zscript. Though I can see where knowing both will be very handy.

Neither of the about options seem to word, the reason I did not use the ({~(%d~)|%s}) before is it does not allow for wild cards inside, and for my trigger to work I need the %d to be a wild card when a number is present. Anyway thanks =)

Why does the number need to be a wild card? If it just a digit then %d or \d+ will work. We need more info, if there's things you're not telling us, we need to know about it or we cant help.

My bad, I thought I went over that in the first post. So in the case when there are multiples of an item the trigger loops the number of need times, entering the command to sell the item to the queue each time.

My pattern differentiates the two

%1 is equal to a number, if it exists. If it doesn't exist then %1 is null and %2 is always equal to the item name. It matches both patterns you gave, for the first one %1=3 and %2="a sword of the hero" for the second %1=null and %2="a flail of destruction"

I must be using it wrong I set the pattern as

^(?:\((?:\s+)?(\d+)\)\s|\s+)([\w ]+)({@armorList})

In zscript a pattern of

Fizgar that got me very close, thank you; however it does not match quite right here is how it looks, I do not know how to make the spaces copy correctly in the forums, in either of the patterns, but...

a sword of the hero = 5 leading white spaces, then the pattern to match
( 3) a sword of the hero = a "(" "1 white space, or none if there are more then 9 items, then the number, then a space then the pattern

When I put this pattern together

I mentioned that the ([\w ]+) was to match the item string, since you added something else to match the item string, you would need to replace it, not add something to it, it would be:

Touche' I misunderstood the way that the regex pattern there work, I thought the ([\w]+) was to match the script, BUT I thought I could pipe that value against the @armorList. It did not occur to me that I should drop the string match. Thanks again chamenas.

GURU Joined: 23 Dec 2000 Posts: 4834 Location: USA

I missed the padding, but that's easy to match for in zscript:

{~(|}([%d%s]){~)|} ({@armorlist})

Well struck, sir. Where's the page for zScript pattern matching? I forget...

From what i'm using to test with this seems to work.

Apprentice Joined: 12 Apr 2004 Posts: 134 Location: USA

Well the pattern works like a charm, I will have to play with to some tomorrow for looping, but is there a check for null? like
#if %1==NULL {add %2 once} {add %2 %1} ?
