>>>>>A "lonely" repeat statement collides with Applescript's only way to ensure the loop executes once.
I don't get what this means. And I don't see how a
repeat until x
ensures anything, particularly when the value x is never used.
If the loop repeats multiple times it will try to evaluate x with every repeat, which is not as efficient as comments.
If that's a programmer's trick, I think it's best forgotten.
>> “repeat … end” is guaranteed to execute at least once, and if you don’t intend it to execute more than once, it shouldn’t be a repeat loop.
repeat 1 times
Will only repeat 1 time and only 1 time, and it even has a use:
repeat
repeat 1 times
do stuff
If a is true then exit repeat
--do stuff you want to do if a is false
end repeat
--do stuff you want to do no matter what a is
end repeat
It allows you to set up a conditional that will bail out on part of a repeat loop, sort of a "next repeat" function. A technique I learned on this list and have used in several scripts.
