rpp 0.2

Description

RPP is a format used to describe REAPER projects. This package is designed to be RPP parser/emitter and uses PLY as parser framework.

Examples

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
Element(tag='REAPER_PROJECT', attrib=(Decimal('0.1'), '4.32', 1372525904), children=[
    Element(tag='RIPPLE', attrib=(0,), children=None),
    Element(tag='GROUPOVERRIDE', attrib=(0, 0, 0), children=None),
    Element(tag='AUTOXFADE', attrib=(1,), children=None)
])

Transform elements into RPP:

>>> from decimal import Decimal
>>> from rpp import Element
>>> rpp.dumps(
...     Element(tag='REAPER_PROJECT', attrib=(Decimal('0.1'), '4.32', 1372525904), children=[
...         Element(tag='RIPPLE', attrib=(0,), children=None),
...         Element(tag='GROUPOVERRIDE', attrib=(0, 0, 0), children=None),
...         Element(tag='AUTOXFADE', attrib=(1,), children=None),
...     ]))
'<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 quering operations with findall, find, iterfind. Note that attribute and text predicates are not supported.

>>> r.find('.//GROUPOVERRIDE')
Element(tag='GROUPOVERRIDE', attrib=(0, 0, 0), children=None)
