RPP is a format used to describe REAPER projects. This package is designed to be RPP parser/emitter and uses PLY as parser framework. It understands the following RPP data types: integer, float, string, uuid, symbolic data (base64).

Import the package:

>>> import rpp

Decode RPP:

>>> r = rpp.loads("""\
<REAPER_PROJECT 0.1 "4.32" 1372525904
  RIPPLE 0
  GROUPOVERRIDE 0 0 0
  AUTOXFADE 1
>
""")
>>> r
RPP([['REAPER_PROJECT', 0.1, '4.32', 1372525904], ['RIPPLE', 0], ['GROUPOVERRIDE', 0, 0, 0], ['AUTOXFADE', 1]])

Transform lists into RPP:

>>> rpp.dumps(
[['REAPER_PROJECT', 0.1, '4.32', 1372525904],
 ['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>'

You can also perform some quering operations:

>>> r.find('GROUPOVERRIDE')
([2], ['GROUPOVERRIDE', 0, 0, 0])

The result is a tuple with first element as list of tree indexes and second as the found value.

To change the value of an item, do the following:

>>> r.update([1], ['RIPPLE', 1])
>>> r
RPP([['REAPER_PROJECT', 0.1, '4.32', 1372525904], ['RIPPLE', 1], ['GROUPOVERRIDE', 0, 0, 0], ['AUTOXFADE', 1]])
