My Ruby Alfred Workflow Loop Stops after "exec"

[sivabudh]

Hello,

 

I'm trying to create a workflow that does image processing to selected images in Finder. For some reason, when the script runs, it would stop executing after the first "exec" is called (e.g. when I call the "convert" command).

 

Here's what my Alfred workflow looks like: http://goo.gl/45BiWd

 

and here's what my Ruby script looks like: http://goo.gl/Fo7ssF

 

I'm sorry. I have spent many hours trying to figure out why it stops after the first image is processed (resized and alpha removed).

 

Does anyone know what the cause could be?

Did you figure this out?

 

As best I can tell, Alfred would only send one filepath to the script.

This article will explain it for you: http://rubyquicktips.com/post/5862861056/execute-shell-commands

 

Basically, Exec exits ruby to run the command. Therefore, if you are in the middle of a loop, you loop will suddenly be exited. The better way is to use backticks `. The article explains it.

 

Sorry, I just saw this post today. Otherwise, I would of spoken up sooner.
