Changes¶

mel2py: numerous fixes / tweaks
system: handle situations where reference node itself is in a non-root namespace

referenceQuery/FileReference.getReferenceEdits: if only one of successfulEdits/failedEdits is given, and it is false, we now assume that the desire is to return the other type (and set that flag to true); formerly, this would result in NO edits being returned
parent no longer raises an error if setting an object’s parent to it’s current parent; this makes it behave similarly to the mel command, and to DagNode.setParent
renameFile now automatically sets the ‘type’ if none is supplied (helps avoid renaming a file to ‘foo.ma’, then saving it as ‘mayaBinary’)

util.path now supports regular expression filtering in addition to globs.
moved moduleDir() from util to mayahook since it is explicitly for pymel.
ensured that all default plugins are loaded when creating the api cache so that we can avoid calculating those each time the plugins are loaded
added a new errors flag to recurseMayaScriptPath for controlling how to handle directory walking errors: warn or ignore
moved pwarnings to ensure that pymel.util is completely separated from maya
adding new sphinx documentation. modifying source docstrings where necessary.
setParent now allows None arg to specify world parent
adopted a standard setuptools-compliant package layout, with pymel as a subdirectory of the top level
forced line numbers on for Mel.eval
changed ipymel to use $MAYA_LOCATION to find mayapy instead of /usr/bin/env
changed datatypes examples to demonstrate the necessity to include a namespace
added groupname, get_groupname, and chgrp to Path class for dealing with unix groups as strings instead of as gid’s
added alias path.Path for path.path so as to follow PEP8
added a new option to pymel.conf to allow disabling of mel initialization in standalone mode.
added ability to set logger verbosity using PYMEL_LOGLEVEL environment variable. great for quick testing.

bug fixes in error handling within path class
fixed issue 65: DependencyNode.listAttr() broken
made sure NameParse objects are stringified before fed to MFnDependencyNode.findPlug()
added a few more reserved types so as to avoid creating them, which can lead to crashes on some setups
