I found the solution. I needed to write 'my' in front of replace_chars when I call the handler.

Hi,

Can I use subroutines in NSAppleScript Alfred workflows? I can't get this code to work:

on alfred_script(q)

tell application "Google Chrome"
	repeat with t in tabs of windows
		tell t
			if URL starts with "http://www.youtube.com/watch" or URL starts with "https://www.youtube.com/watch" then

				set new_URL to URL			
				set new_URL to replace_chars(URL, "youtube", "yourepeat")
				do shell script "/usr/bin/open -a '/Applications/Google Chrome.app' " & new_URL
			
			end if
		end tell
	end repeat
end tell

end alfred_script


to replace_chars(this_text, search_string, replacement_string)
	set AppleScript's text item delimiters to the search_string
	set the item_list to every text item of this_text
	set AppleScript's text item delimiters to the replacement_string
	set this_text to the item_list as string
	set AppleScript's text item delimiters to ""
	return this_text
end replace_chars

Trying to debug the issue, I pasted the code in Automator (and made a few changes of course), and here's the syntax error I get:

Google Chrome got an error: item 1 of every tab of every window doesn’t understand the “replace_chars” message.

I tried putting the 'to replace_chars' subroutine in other places in the code, but it doesn't work.

Any help would be grealtly appreciated it.

Hi I greatly appreciated your workflow in the past. I tried to fix it but the problem doesn't seem to come from the YouTube API, but maybe I'm wrong. Here's my results so far.

If I visit a YouTube page, pause the video, and type the following code in the console, it works (the video plays):

var player = document.getElementById('movie_player');
player.startVideo();

When I type 'ytp' in the alfred bar though, the video doesn't play, and the console outputs 'Uncaught error: getPlayerState() not a function.' I checked on the API, the functions getPlayerState() and pauseVideo() are still there and are the same. The problem I found is that somehow the line 'var player = document.getElementById('movie_player');' in the Alfred workflow doesn't change the player variable. I tested this by typing 'player' in the Chrome console. It outputs a different default player object, for which of course there's no getPlayerState, etc. functions.

My conclusion was that... I was confused. I thought maybe the default player object already present is 'protected' and can't be overridden when Alfred executes the javascript code?

If you can get this action (ytp) to work, I am willing to update the rest of the workflow. 

Thank you very much.
