"""
Name: 'Scripts Config Editor'
Blender: 236
Group: 'System'
Tooltip: 'View and edit available scripts configuration data'
"""

__author__ = "Willian P. Germano"
__version__ = "0.1 2005/04/14"
__email__ = ('scripts', 'Author, wgermano:ig*com*br')
__url__ = ('blender', 'blenderartists.org')

__bpydoc__ ="""\
This script can be used to view and edit configuration data stored
by other scripts.

Technical: this data is saved as dictionary keys with the
Blender.Registry module functions.  It is persistent while Blender is
running and, if the script's author chose to, is also saved to a file
in the scripts config data dir.

Usage:

- Start Screen:

To access any available key, select it from (one of) the menu(s).

Hotkeys:<br>
   ESC or Q: [Q]uit<br>
   H: [H]elp

- Keys Config Screen:

This screen exposes the configuration data for the chosen script key.  If the
buttons don't fit completely on the screen, you can scroll up or down with
arrow keys or a mouse wheel.  Leave the mouse pointer over any button to get
a tooltip about that option.

Any change can be reverted -- unless you have already applied it.

If the key is already stored in a config file, there will be a toggle button
(called 'file') that controls whether the changes will be written back to
the file or not.  If you just want to change the configuration for the current
session, simply unset that button.  Note, though, that data from files has
precedence over those keys already loaded in Blender, so if you re-run this
config editor, unsaved changes will not be seen.

Hotkeys:<br>
   ESC: back to Start Screen<br>
   Q: [Q]uit<br>
   U: [U]ndo changes<br>
   ENTER: apply changes (can't be reverted, then)<br>
   UP, DOWN Arrows and mouse wheel: scroll text up / down

Notes:

a) Available keys are determined by which scripts you use.  If the key you
expect isn't available (or maybe there are none or too few keys), either the
related script doesn't need or still doesn't support this feature or the key
has not been stored yet, in which case you just need to run that script once
to make its config data available.

b) There are two places where config data files can be saved: the
bpydata/config/ dir (1) inside the default scripts dir or (2) inside the user
defined Python scripts dir
(User Preferences window -> File Paths tab -> Python path).  If available,
(2) is the default and also the recommended option, because then fresh Blender
installations won't delete your config data.  To use this option, simply set a
dir for Python scripts at the User Preferences window and make sure this dir
has the subdirs bpydata/ and bpydata/config/ inside it.

c) The key called "General" in the "Other" menu has general config options.
All scripts where that data is relevant are recommended to access it and set
behaviors accordingly.
