Synopsis

loadPlugin [-addCallback script] [-allPlugins] [-name string] [-quiet] [-removeCallback script] string [string...]

loadPlugin is undoable, NOT queryable, and NOT editable.

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.mll" the name used in the Maya's registry will be "newNode". This value as well as that value with either a ".so", ".mll" or ".bundle" extension can be used as valid arguments to either the unloadPlugin or pluginInfo commands.

Return value

string[] the internal names of the successfully loaded plug-ins

Flags

addCallback, allPlugins, name, quiet, removeCallback
Long name (short name) Argument types Properties
-name(-n) string create
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.
-allPlugins(-a) create
Cause all plug-ins in the search path specified in MAYA_PLUG_IN_PATH to be loaded.
-quiet(-qt) create
Don't print a warning if you attempt to load a plug-in that is already loaded.
-addCallback(-ac) script create
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 "%s" where 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.
-removeCallback(-rc) script create
Removes a procedure which was previously added with -addCallback.
