Semi-Automatic replacements
===========================

We recommend to use commands below after commiting previous changes. It allows you to check differences.

The commands doesn't update code fully and usually you need to continue updates manually.

.. code-block:: sh

    # pool -> env
    find . -type f -name '*.py' | xargs sed -i 's/self.pool/self.env/g'
    # remove cr, uid
    find . -type f -name '*.py' | xargs sed -i 's/(cr, [^,]*, /(/g'
    find . -type f -name '*.py' | xargs sed -i 's/(self, cr, [^,]*, ids/(self/g'
    find . -type f -name '*.py' | xargs sed -i 's/(self, cr, uid, /(self, /g'
    find . -type f -name '*.py' | xargs sed -i 's/, context=[^,)]*//g'
