So I want to get the contents of some packages and do things with them. However my recursive code dies because, apparently, applescript doesn't know what to do with the packages. Suggestions?

set main_folder to (choose folder)
set list_of_files to ProcessFolder(main_folder)
----------
-- recursive subroutineon ProcessFolder(the_folder)
    set file_list to {}
    tell application "Finder"
        try
            set file_list to (name of every file of the_folder)
        on error -- there are no files of this type
            -- do nothing
        end try
        set folder_list to (every folder of the_folder)
    end tell
    repeat with this_folder in folder_list
        set file_list to file_list & ProcessFolder(this_folder)
    end repeat
    return file_list
end ProcessFolder

AppleScript isn't the issue here -- the Finder is. The Finder attempts to make its scripting view match what you see in its GUI (this is generally considered to be a good thing); therefore, packages are not considered to be folders. However, they do still have elements, just like folders do (though the dictionary lies on this point), so you should be able to fix your script by saying "set folder_list to (every folder of the_folder & every package of the_folder)".


However, you should be very careful here. In general, doing a recursive file tree scan ignoring the package-ness of items is a bad idea -- packages have deliberately constructed contents, and mucking with them the same as you would with any other folder that just happens to be lying around is almost certainly wrong. Not that dipping into packages is verboten by any means, but what you ought to do is locate the packages first, and then process exactly those items.
