Hi,
I've implemented ecasound effect parameter parsing for python.
can temporarily be reached at:
http://www.pp.htv.fi/jhalttun/ecaeffect.py
sample session:
>>> import ecaeffect
>>> ecaeffect.parse_internal ()
>>> ecaeffect.get_description ('eca')
('Advanced compressor', 'Advanced compressor')
>>> ecaeffect.get_params ('eca')
[{'upper': 200.0, 'step': 1, 'name': 'peak-limit-%', 'lower': 0, 'value': 100.0, 'page': 10}, {'upper': 1, 'step': 0.01, 'name': 'release-time-sec', 'lower': 0, 'value': 0.0, 'page': 0.050000000000000003}, {'upper': 2.0, 'step': 0.10000000000000001, 'name': 'fast-crate', 'lower': 0, 'value': 1.0, 'page': 0.5}, {'upper': 1, 'step': 0.01, 'name': 'overall-crate', 'lower': 0, 'value': 0.0, 'page': 0.050000000000000003}]
>>> ecaeffect.parse_ladspa ()
>>> ecaeffect.get_description ('mbeq')
('Multiband EQ', "Multiband EQ - Author: 'Steve Harris <steve_AT_plugin.org.uk>'")
>>> ecaeffect.get_params_info ('mbeq')

-----------------
please note that in get_params(), the "step" and "page" attributes are determined heuristically. Also when upper bound and lower bound are not set, heuristic method is used.
TODO:
-cacheing of parsed values
Kai, could there be some kind of hash value that would indicate whether there has been changes to operator mappings?
-finalizing the API
-documentation
Anything else?
