Dominique Dutoit has released an F-Script action for Automator. It lets you add custom F-Script code within your Automator processes. You can get it here.

The input of the action (i.e., the output of the previous action) is automatically bound to a variable named “input” in the F-Script workspace. Usually, it is an NSArray object. The output of the action is the value of the last F-Script expression executed in the custom F-Script code (automatically boxed in an NSArray if needed).
You’ll need to have the F-Script framework (download here) installed in /Library/Frameworks/ or ~/Library/Frameworks/.
Enjoy!
Hi, thank you for the announcement. Just to let you know that the executable binary is located here: http://www.hitoro.net/trunk/
When I try to use the action on Leopard, I get an error that says the Workflow action is not an executable.
Is there a way to avoid this issue?
TIA.
@Kiam
You must put FScript.framework in one of the folowing directories on your system: /Library/Frameworks/ or ~/Library/Frameworks/ (where ~ stands for your home directory)
You’ll find FScript.framework inside the package at http://www.fscript.org/download/FScript_2_0_alpha.zip
If it doesn’t work, let me know on which architecture you are running (Intel, PPC ?) and if you have additional error information (e.g. additional information shown in the Mac OS X Console)
It works. I simply gave the wrong name to the folder I created in my home directory. I moved the framework in the system folder, and now the action works perfectly.
I got confused from the message gave from Finder, and thought the .zip archive was corrupt, or I had to set a flag for the file to be known as executable.
Thanks for the help.
