Script / folder icon question

Question

Would there be a script I can run in Apple Script Editor that changes several folder icons inside another folder all at once?

Answer 1

The easiest way to do this would be to create a Service Workflow using Automator, then you can select the desired items in a Finder window, and right-click to bring up a contextual menu where you can choose the service.  Unfortunately, dealing with Automator is a bit of a pain sometimes, but Lion's Open Finder Items action (which doesn't want to cooperate with multiple items) can be worked around with an AppleScript action.  I've tested the following workflow and it works for me (the Get Value of Variable action can be left out if you don't want the selected folders themselves to be changed).  I've also updated my Set Icon application with dialogs that work better and included a progress indicator (for those 'tons of folders') - the application also uses a different bundle identifier, so you'll want to get the new version since that is what the Automator workflow looks for.  The application can still be used on its own by double-clicking or dropping items on it (it won't decend into folders, though).
The workflow:
The Script (paste into the Run AppleScript action):
property bundleID : "com.Menace-Enterprises.Cocoa-AppleScript.Set-Icon"
on run {input, parameters}
  try -- use Spotlight to find the Set Icon application, wherever it may be
    set appPath to first paragraph of (do shell script "mdfind " & quote & "kMDItemCFBundleIdentifier == " & quoted form of bundleID & quote)
  on error errmess number errnum -- oops, not found
    activate me -- bring dialog to front
    display alert "Error " & errnum message "Application 'Set Icon' was not found."
    error number -128 -- cancel
  end try
  tell application "Finder" to open input using (appPath as POSIX file)
  return input
end run
