I've found there are times when it's convenient to silence the pymel logger
with a context manager. One example would be getting the names of nodes
that were deleted *after* they were deleted. The problem is that node.name()
will still return the name, but warn that the node doesn't exist.
One caveat is that there is no promise that the name of the Pymel logger
won't change. Pymel seems fairly mature though, and I'd imagine a package
re-organization would warrant a new major version.
class SilencePymelLogger(object): def __init__(self):
self.level = 10 self.pmLogger =
logging.getLogger('pymel.core.nodetypes')
def __enter__(self): self.pmLogger.propagate = 0
self.level = self.pmLogger.level self.pmLogger.setLevel(50)
return self
def __exit__(self, exctype, excval, exctb):
self.pmLogger.propagate = 1 self.pmLogger.setLevel(self.level)
from __future__ import with_statement
with SilencePymelLogger():
#do stuff
