macOS AppleScript Repeat For x Seconds

You just want it to run a loop as fast as possible for a specific duration?


The above code will run through a loop for one second. Change the value in the if statement to adjust the amount of time. Note that you can also specify partial seconds, such as 2.5.

Can't help you with your other problem.

Code:

set start_value to do shell script "ruby -e 'print Time.now.to_f'"
repeat while true
    -- Your code goes here
    set end_value to do shell script "ruby -e 'print Time.now.to_f'"
    if end_value - start_value ≥ 1 then
        exit repeat
    end if
end repeat

ytk When I run your code without adding anything it runs as expected, runs for 1 second then stops. But when I add my code it stops after running my code once (below). It returns 7 then it ends, instead of continously running for 10 seconds. Is there a way to run the code continously for the time listed in the code?

set start_value to do shell script "ruby -e 'print Time.now.to_f'"


repeat while true


set end_value to do shell script "ruby -e 'print Time.now.to_f'"


return "7"


if end_value - start_value ≥ 10 then


exit repeat


end if


end repeat

I'm honestly not sure what you are trying to accomplish here. A return statement will immediately end any loop it is in, and return the value specified to the calling function. I don't even know what it would mean to repeatedly return a value; returning a value is not something that you can do more than once within a given context.

Maybe if you explain what you're trying to actually do, I can help you figure out how to go about it.
