pymel.core.system.loadPlugin

static system.loadPlugin(*args, **kwargs)

Load plug-ins into Maya. The parameter(s) to this command are either the names or pathnames of plug-in files. The convention for naming plug-ins is to use a .so extension on Linux, a .mll extension on Windows and .bundle extension on Mac OS X. MAYA_PLUG_IN_PATH will be searched looking for a file with the given name. If you specified the plug-in without an extension, the appropriate one for the platform will be automatically appended. When the plug-in is loaded, the name used in Maya’s internal plug-in registry for the plug-in information will be the file name with the extension removed. For example, if you load the plug-in newNode.mllthe name used in the Maya’s registry will be newNode. This value as well as that value with either a .so, .mllor .bundleextension can be used as valid arguments to either the unloadPlugin or pluginInfo commands.

Flags:

Long name (short name)		Argument Types	Properties
addCallback (ac)		script
	Add a MEL or Python callback script to be called after a plug-in is loaded. For MEL, the procedure should have the following signature: global proc procedureName(string $pluginName). For Python, you may specify either a script as a string, or a Python callable object such as a function. If you specify a string, then put the formatting specifier %swhere you want the name of the plug-in to be inserted. If you specify a callable such as a function, then the name of the plug-in will be passed as an argument.
allPlugins (a)		bool
	Cause all plug-ins in the search path specified in MAYA_PLUG_IN_PATH to be loaded.
name (n)		unicode
	Set a user defined name for the plug-ins that are loaded. If the name is already taken, then a number will be added to the end of the name to make it unique.
qObsolete (q)		bool
quiet (qt)		bool
	Don’t print a warning if you attempt to load a plug-in that is already loaded.
removeCallback (rc)		script
	Removes a procedure which was previously added with -addCallback. Flag can have multiple arguments, passed either as a tuple or a list.

Derived from mel command maya.cmds.loadPlugin

Example:

import pymel.core as pm

# Load the plug-in named "newNode" into Maya.
#
pm.loadPlugin( 'newNode.py' )

# Load all the plug-ins found in all the directories that are
# included in MAYA_PLUG_IN_PATH.
#
pm.loadPlugin( allPlugins=True )
