This module was written to make it simple to add custom operators for view
inheritance.

**Table of contents**

.. contents::
   :local:

Usage
=====

**Change a python dictionary (context for example)**


.. code-block:: xml

    <attribute name="$attribute" operation="python_dict" key="$key">
        $new_value
    </attribute>

Note that views are subject to evaluation of xmlids anyways, so if you need
to refer to some xmlid, say ``%(xmlid)s``.

**Add to values in a list (states for example)**

.. code-block:: xml

    <attribute name="$attribute" operation="list_add">
        $new_value(s)
    </attribute>

**Remove values from a list (states for example)**

.. code-block:: xml

    <attribute name="$attribute" operation="list_remove">
        $remove_value(s)
    </attribute>

**Move an element in the view**

This feature is now native, cf the `official Odoo documentation <https://www.odoo.com/documentation/12.0/reference/views.html#inheritance-specs>`_.



Known issues / Roadmap
======================

* add ``<attribute operation="json_dict" key="$key">$value</attribute>``
* support ``<xpath expr="$xpath" position="move" target="xpath" target_position="position" />``
* support an ``eval`` attribute for our new node types
