I have this very simple macro that can be executed from a pallet that is displayed when a certain dialogue box is opened. It selects all text in an input box and reduces the selection with one character at the end of the selection:
It would be nice if this macro can be used multiple times, each time the selection will be further reduced with one extra character (from the right).
How can I achieve this?
I can think of this solution, but find it a little clumsy (a lot of code):
- Set a variable firstExecution is True when the macro is executed one time, make sure that the CMD+A isn't executed if firstExecution is True.
- Create a second macro that is triggered when the specific dialogue box is closed and that sets the variable firstExecution to False again.
Perhaps it is better to use a counter.
Edit: How about this approach: first I determine the length of any existing selection. Then I simulate Command+A and determine the length again. If the first selection is smaller, I reduce the selection by the difference plus one.
Any complex solution is likely to require a lot of code and logic, and quite often something that seems like it should be simple turns out to be more than a little bit complex.
In this case you say you will always reduce the number of characters by 1 (from the right)?
So – looking slightly outside the box a simple solution would be to use a regular expression that eats the rightmost character upon each execution.
No character counting required.

Thanks for your help! I'm actually not trying to reduce a string but to reduce a selection. (I'm sure that your macro will come in handy for any of my other purposes ).
I went a long way with my macro, calculating lengths of selections and comparing and then I started anew and wrote something quite simple, that actually worked:
So, what's so special about this?
Blush , nothing ... except when you use this snippet in two input boxes at the 'same' time:
Then you'll have this: on a click, the selection in two input boxes is shrunk:
And the nice thing is that you can click multiple times, to further shrink the selections.
On a side note: The dialogue box shown will add both the long forms (here the plural) and any existing selection(s), the short forms (here the singular). Quite nifty.

You tend to learn a lot when you do that.
