Applescript opens new window for everything when run

Question

I have the following code I did for a tweetbot keyboard shortcut to open tweetbot and create a new tweet.

on run {input, parameters}
    activate application "Tweetbot 2"
        tell application "System Events" to keystroke "n" using command down
    return input
end run

However, it always opens a new window for anything that is run in the background as well. This only happens when Tweetbot is not already running.

How can I fix this ?

Answer 1

This is because the application is not in the foreground.

The activate command will not wait the response of the application when the application is not scriptable. So the script executes immediately the keystroke command, therefore the keystroke will be intercepted by another application.

activate application "Tweetbot 2"
tell application "System Events"
  tell process "Tweetbot 2"
      repeat until exists
          delay 0.4
      end repeat
      set frontmost to true
      delay 0.2
      keystroke "n" using command down
  end tell
end tell
