It would be very convenient if we had option to execute timer only once.

For instance:

Why not turn the timer off at the end of the timer routine? I'm not sure I understand the request. Could you please give a better example? If you need to run a timer once, you can turn the timer off just before the Return line. This can also be done conditionally. If you just need a delay before executing something then you can use Sleep. If you're using a timer only to start a separate thread then that seems like a separate request. Maybe I'm misunderstanding...

Also, why OnTimer ? It sounds more like a notification event than a command.

JavaScript has setTimeout/setInterval and this would be like an extension of both. It's another convenience thing.

If that can be done in an hour, why not ?
New Features are usualy measured in weeks, not hours

Anyway, U can always programm in ASM if you want no syntax suggars and lot of code.

Although I'm not in favor of adding "OnTimer" at this time (since that would be costly in code size and development time), SetTimer could be altered to accept negative periods. Such a period would mean "run this timer only once".

This would be easy to add; but I'm not sure the convenience it provides is enough to justify it. What do you think?

[majkinetor]

I think you should think no more. Negative timer is good, and much better then using additional param. I told you already it is common around to have that, as you tend to ask that question when judging value of something.

Convenience functionalities might have a lower priority than real features, but that's what makes a language friendly... Almost everything can be done i current AHK, but some things are lengthly and error prone.

If they are very easy to implement (like the negative value), and need little to add to the doc, it worth considering.

This wish reminds me of the ToolTip time-out wish, still in the pending list: we often want to show a tooltip for a given time, and the workaround shown in the manual is to use a timer, which is annoying because you have to add 5 lines and a label just for this. At least this wish will remove one line...

oh, sry, syntactic sugar.

Now everybody know exactly what it is.

SetTimer has been improved to treat negative periods as "run only once". Thanks for the idea.
