Read and write Reaper RPP files with Python.
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.
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.

.. 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'], ])
