My boomerang won't come back (return, actually)

[dalkin]

The following script populates a scrolling list field on the first card to open when the stack is launched, with the names of cards created at another part of the stack. They are created by copying a template card that is pre-populated with various fields and buttons etc. At first run though, the script puts a return when there are no other cards yet created. I can't seem to tell it NOT to put a return unless a new card is created. Any tips?

Code: Select all

on preOpenCard
   repeat with i = 1 to the number of cards
      if exists (group "Navigation" of card i) then
      put field "Title" of card i & return after tNames
      end if
   end repeat
   put tNames into field "Index" of card "Navigation"
end preOpenCard

My father's favourite tips were never to run up stairs and never bet odds-on on 2yo races. More sophisticated tips are welcome here.

Hi Dalkin,

here's another good one:
Spots of red wine disappear immediatley if you pour ink over them!

OK, just add a line

Code: Select all

on preOpenCard
   repeat with i = 1 to the number of cards
      if exists (group "Navigation" of card i) then
      put field "Title" of card i & return after tNames
      end if
   end repeat
   
   ## EITHER:
   delete char -1 of tNames
   ## OR: 
   ## filter tNames without EMPTY
   
   put tNames into field "Index" of card "Navigation"
end preOpenCard

Best

Rolf Harris's boomerang came back with a vengeance!

Hi.

Another way to do this would be to use the "newCard" message, perhaps in the stack script. In that way you can build your new card list directly, as each one is created (pseudo)

Code: Select all

on newCard
   addInformationAboutTheNewCardToAFieldOnCardOne
end newCard

At first run though, the script puts a return when there are no other cards yet created. I can't seem to tell it NOT to put a return unless a new card is created.

Not sure i entirely understand, but i think you're asking for how the list not to end in a return?
Please ignore if i misunderstood! If not, the offending statement is: put field "Title" of card i & return after tNames

You can either do what Klaus says and either delete the last char or remove empty lines.

Or another way to go about it is to put the return before the title of card, eg:

Code: Select all

on preOpenCard
   put field "Title" of card 1 into tNames -- there will always be at least 1 card!
   repeat with i = 2 to the number of cards
      if exists (group "Navigation" of card i) then
      put return & field "Title" of card i after tNames
      end if
   end repeat
   put tNames into field "Index" of card "Navigation"
end preOpenCard

hope that helps,
Stam

I love you guyz. I didn't get to try them all because Klaus had an early victory with "filter tNames without EMPTY' - works a treat!

In my working life, I worked as a political cartoonist on newspapers and magazines, with several early forays into multimedia. So imagine my surprise when I ended up in a stretch limo with 6 other cartoonists and Rolf Harris in a pink suit on our way to the annual Australian Cartoonists Association dinner in Sydney where Harris was the guest speaker. If only we had known, way back then.

For aficionados of popular culture, I present the aforementioned song as it was best sung. Charlie Drake wrote the song in 1961 and it was produced by George Martin. Fancy that.
