[kevin007]

Hi ALL

I have an variable that contain following string .

[xshift={\hzwidth+10} ,yshift={-\vtheight+15}, rotate=30]

I want only numbers from above string and save these three numbers to three different variable

Hi Kevin,

If you don't have any allergia with regex, here is one solution:

Code: Select all

if matchText( S, "\+(\d+)}.+\+(\d+)}.+=(\d+)]", n1, n2, n3) then
      put "Find: " & n1 && n2 && n3
   else
      put "Sorry, no match!"
   end if

Just typed it out of my head, so beware of possible typos.

Best,

Thierry

@Thierry
superb coding

Thierry can do more with one line of regex than I can in a handful of lines of "ordinary" code.

But are you OK with that, or do you want to talk about those handfuls?

Hi Craig,

Mmm, I have nothing to do with this fact; that's the power of regex: concise and powerful for
pattern matching.

But are you OK with that, or do you want to talk about those handfuls?

Well, I think it will be nice to have some 'Livecodish' solutions, and let the readers learn,
compare and experiment out of them.
My 2 cents,

@Kevin: Re-reading my post, I've noticed there are some room for speeding up the regex.
If you feel it's too slow, just let me know.

But now, I have to unplug all my computers as a big storm is coming.

Bonsoir Thierry,

So be careful when talking to me that I'm not going to cast a spell on you

Schönes Wochenende
