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.
Import the package:
>>> import rppDecode 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=['0.1', '4.32', '1372525904'], children=[
['RIPPLE', '0'],
['GROUPOVERRIDE', '0', '0', '0'],
['AUTOXFADE', '1'],
])Transform elements into RPP:
>>> 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.
>>> 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'],
])
