RPP

RPP is a format used to describe REAPER <http://reaper.fm>_ projects. This package is designed to be an RPP parser/emitter and uses PLY <http://www.dabeaz.com/ply/>_ as a parser framework.

Examples

Import the package:

.. code-block:: python

import rpp

Decode RPP:

.. code-block:: python

r = rpp.loads("""
<REAPER_PROJECT 0.1 "4.32" 1372525904 RIPPLE 0 GROUPOVERRIDE 0 0 0 AUTOXFADE 1

""")

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'], ... ])) '<REAPER_PROJECT 0.1 4.32 1372525904\n RIPPLE 0\n GROUPOVERRIDE 0 0 0\n AUTOXFADE 1\n>\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'], ])
