Suggestion to inform users that default_root behaviour has changed. #120

Hi Scott,

I just figured out that default_root: project_root no longer works, and that as of 1.5.1 you need to set up individual settings for default_root in for each of the new, move, copy commands:

new_file_default_root
rename_file_default_root
copy_file_default_root

be84395#diff-0994d3f547d1105beb6a24ace4f44472R412

Here in command_base.py, could I suggest that you check for existence of the above keys in settings, and if not, then use the original default_root settings? This would allow the current installations to continue to work as is but allow fine tuning of roots if needed.

My Python has pretty much gone by the wayside as I haven't touched it since my 2 week stint last year, but something like this (excuse the Ruby-like code). I can't remember if self.settings.get returns nil or blank string, but something along these lines.

    def _get_default_root(self):
        root_setting_value = self.get_default_root_setting()
        root_setting = self.settings.get(root_setting_value) || self.settings.get(DEFAULT_ROOT_SETTING)
        if root_setting == DEFAULT_ROOT_SETTING:
            return self.settings.get(DEFAULT_ROOT_SETTING)
        return root_setting

Keep up the great work! I use ANF every single day I code!
