Listing directory contents

AppleScript
#1

This came up elsewhere, but the code might be useful for people here too. It’s what I use when I want to check the contents of a complex folder hierarchy.

The resulting .rtf file is saved in your tmp folder, and opened in your default editor for .rtf files. File names are in blue, folder names in red, with the rest of the path in light gray. Change the value of the fullPaths property depending on whether you want to see the full paths or not. It’s best run from a scripts menu, like the built-in one or FastScripts.

It requirs 10.10, although you could put it in a Script Library and use it under 10.9.

use AppleScript version "2.4" -- 10.10
use scripting additions
use framework "Foundation"
use framework "AppKit"
property fullPaths : false -- set to true to list full paths rather than relative paths

tell application "Finder"
	try
		set theTarget to target of Finder window 1 as alias
	on error
		error number -128
	end try
end tell

-- make URL
set targetURL to current application's |NSURL|'s fileURLWithPath:(POSIX path of theTarget)
if not fullPaths then set targetLength to (targetURL's |path|()'s |length|()) + 1 -- use to trim paths
