Complaining on "try" statement Topic is solved

[slishnevsky]

Hi.

Why is AHK complaining on try statement?

Code: Select all

CreateTimer() {
  timeout := InputBox('Set timer interval (in minutes)', 'Timer').Value
  if (!IsInteger(timeout))
    Exit
  SetTimer(() => (
    SoundPlay('WakeUp.mp3')
    MsgBox('Сработал таймер!', 'Таймер', 'Icon! OK')
    try SoundPlay('Nonexistent.mp3') ; Complains on the usage of try statement here
  ), timeout * 60000)
}

1. What does that mean?
2. Post the script instead of an image of it.
3. Post a screenshot of the error message.

Try is not a valid part of an expression which you are trying to define as part of a fat arrow function. The syntax for that is () => expr, where expr is an expression.

Makes sense. Then, how should I stop playing audio there?
If I move try SoundPlay('Nonexistent.mp3') outside the arrow function, the interpreter doesn't complain, but the audio keeps playing...
According to the documentation, To stop a file that is currently playing, use SoundPlay on a nonexistent filename as in this example: try SoundPlay "Nonexistent.avi".

Code: Select all

CreateTimer() {
  timeout := InputBox('Set timer interval (in minutes)', 'Timer').Value
  if (!IsInteger(timeout))
    Exit
  SetTimer(() => (
    SoundPlay('WakeUp.mp3')
    MsgBox('Сработал таймер!', 'Таймер', 'Icon! OK')
  ), timeout * 60000)
  try SoundPlay('Nonexistent.mp3') ; Doesn't complain, but keeps playing
}

Just use a regular function instead of a fat arrow function.
