Does not work in Alfred 3

[raygan]

In the recently released Alfred 3 I'm able to get as far as selecting the display, but no list of resolutions is displayed. When I select the display, Alfred is dismissed.

I'm using Alfred 3 and it's working fine for me, haven't changed a thing. I'm on Yosemite though, I haven't upgraded to El Capitan

Do you know how to run workflows on debugging mode? if so, please check if you see any errors while trying to list/change resolutions and let me know

Thanks!

[raygan]

Sure. I am running El Capitan, and have two 1080p Asus monitors. When I try to set the resolution for one of them, the Alfred window disappears without displaying any resolutions after I select the monitor. Here’s what I get in the debug window:

[2016-06-02 11:25:02][input.scriptfilter] <items><item valid='yes'><title>Display: ASUS VS239</title><arg>0</arg><subtitle>Change resolution for display ASUS VS239</subtitle><icon>icon.png</icon></item><item valid='yes'><title>Display: ASUS VS239</title><arg>1</arg><subtitle>Change resolution for display ASUS VS239</subtitle><icon>icon.png</icon></item></items>

[2016-06-02 11:25:04][action.script] Processing output of ‘output.notification' with arg ''

And here's a short video of what's happening if that helps

I tried resetting the list of resolutions but that didn't change anything.

Thanks for looking into it, let me know if there's anything else I can do to help. I go to use this workflow at least a couple of times per day, and forget it's not working each time. It had really become a part of my workflow! Thanks for making it in the first place.

hmm, I sadly don't have a 2nd monitor to test. There're no errors in your output also. I'll try to check it later :/

I have the same error, but my debugging output actually prints an ActionScript error. I'm on OSX 10.10.5, MacBook 13" Early 2015 and my external monitor is 3840 x 2160 @ 60 fps .

[2016-06-07 09:34:53][ERROR: action.script] 23:31: syntax error: A “"” can’t go after this identifier. (-2740)

So, found what's causing it on my end:

You're calling Alfred 2 directly in set_resolution.rb :

if query =~ /^\d+$/
  `osascript -e 'tell app "Alfred 2" to search "setresolution #{query} "'`
else

Changing "Alfred 2" to "Alfred 3" solves it, but would break Alfred 2 support. So I will file no PR atm.

I found references to Alfred 2 in the alfred-workflow gem, but that seems not to be an issue.

[ramiroaraujo]

OMG haha, why is it working then! :D Thanks!, I'll figure out how to fix that for sure

Works fine for me in Alfred v3 on El Capitan without any changes. I only tried it on the Built-in Retina Display, though.

[eppfel]

@dubstrike When I remember correctly, this only is an issue with multiple displays.

[raygan]

That's correct, it's only an issue on my desktop Mac with two 1080p monitors attached. Works fine on my 15" Retina MacBook Pro.

[ramiroaraujo]

I don't have an easy way to debug and fix this since I don't have 2 displays Any help (PR) appreciated :)

This solves it for me, but I will not make a PR for changing a number. 😄 Also, this will break it for Alfred 2, I guess. Best thing would be to avoid this "hack" completely, but this is a little bit more work and I'm really not an expert on Alfred workflows or ruby, in particular.
