RPP

===

RPP is a format used to describe `REAPER `_ projects. This package is designed to be an RPP

parser/emitter and uses `PLY `_ as a parser framework.

Examples

--------

Import the package:

.. code-block:: python

   >>> import rpp

Decode RPP:

.. code-block:: python

   >>> r = rpp.loads("""\

   

   """)

   >>> r

   Element(tag='REAPER_PROJECT', attrib=['0.1', '4.32', '1372525904'], children=[

       ['RIPPLE', '0'],

       ['GROUPOVERRIDE', '0', '0', '0'],

       ['AUTOXFADE', '1'],

   ])

Transform elements into RPP:

.. code-block:: python

   >>> from rpp import Element

   >>> rpp.dumps(

   ...     Element(tag='REAPER_PROJECT', attrib=['0.1', '4.32', '1372525904'], children=[

   ...         ['RIPPLE', '0'],

   ...         ['GROUPOVERRIDE', '0', '0', '0'],

   ...         ['AUTOXFADE', '1'],

   ...     ]))

   '\n'

``Element`` mimics the interface of xml.etree.ElementTree.Element_. You can perform querying operations with

``findall``, ``find``, ``iterfind``. Note that attribute and text predicates are not supported.

.. _xml.etree.ElementTree.Element: https://docs.python.org/3/library/xml.etree.elementtree.html#xml.etree.ElementTree.Element

.. code-block:: python

   >>> groupoverride = r.find('.//GROUPOVERRIDE')

   >>> groupoverride

   ['GROUPOVERRIDE', '0', '0', '0']

   >>> groupoverride[1:] = ['9', '9', '9']

   >>> r

   Element(tag='REAPER_PROJECT', attrib=['0.1', '4.32', '1372525904'], children=[

       ['RIPPLE', '0'],

       ['GROUPOVERRIDE', '9', '9', '9'],

       ['AUTOXFADE', '1'],

   ])
