Using 'setup.py' command line script
####################################

.. note:: To manage preferences using ``setup.py`` script, you must use
        the Python interpreter that is normally used to run pgAdmin to ensure
        that the required Python packages are available. In most packages, this
        can be found in the Python Virtual Environment that can be found in the
        installation directory. When using platform-native packages, the system
        installation of Python may be the one used by pgAdmin.


Manage Preferences
******************

Get Preferences
***************
To get all the preferences listed, invoke ``setup.py`` with ``get-prefs`` command line option.
You can also get this mapping by hovering the individual preference in the Preference UI dialog.

.. code-block:: bash

    /path/to/python /path/to/setup.py get-prefs

Save Preferences
****************
To save the preferences, invoke ``setup.py`` with ``set-prefs`` command line option, followed by username,
preference_key=value and auth_source. Multiple preference can be given too by a space separated.
If auth_source is not given, Internal authentication will be consider by default.

.. code-block:: bash

    /path/to/python /path/to/setup.py set-prefs user1@gmail.com sqleditor:editor:comma_first=true

    # To specify multiple preferences options
    /path/to/python /path/to/setup.py set-prefs user1@gmail.com sqleditor:editor:comma_first=true sqleditor:keyboard_shortcuts:toggle_case=true

    # to specify an auth_source
    /path/to/python /path/to/setup.py set-prefs user1@gmail.com sqleditor:editor:comma_first=true --auth-source=ldap

Updating Preferences preferences.json
*************************************
To update preferences defined in json file, simply run ``setup.py `` with ``set-prefs`` command followed by username
and JSON file containing the preferences.

.. code-block:: bash

    /path/to/python /path/to/setup.py set-prefs user1@gmail.com --input-file /Users/yogeshmahajan/Desktop/pref.json

JSON format
***********

The JSON file simply contains preference_key=value. Preference key value mapping can be obtained by hovering the
individual preference in the Preference UI dialog.

The following is an typical example for preferences.json :

.. code-block:: python

    {
        "preferences":
            {
                "browser:display:show_system_objects":  true,
                "browser:display:show_user_defined_templates": true,
                "browser:display:confirm_on_refresh_close": false,
                "misc:themes:theme": "dark",

            }
    }
