Returning a string from a command plugin?

[Russel Rehmund]

Anyone know how to properly work this?  Any examples or links to documentation would be appreciated.

I'm trying to return a string from my command plugin, though I'm not even sure it's possible.  The string is the name of a camera that I've created.

I'd like to be able to do this:

camera = cmds.my_command()

Here's my initialize function:

def initializePlugin(mobject):

    mplugin = omMPx.MFnPlugin(mobject, author, version, 'Any')

    try:

        cam = mplugin.registerCommand(kPluginCmdName, cmdCreator, syntaxCreator)

        log.info("Successfully registered plugin: {0}".format(kPluginCmdName))

        if cam:

            return cam

    except Exception as e:

        log.critical("Failed to register command: {0}".format(kPluginCmdName))

        log.critical(traceback.format_exc(e))

        raise

My doIt function:

    def doIt(self, args):

        """ Command execution. """

        arg_data = om.MArgDatabase(self.syntax(), args)

      

       ... flags parsing

        # Run the turntable code here.

        cam = main(...)

        return cam

Am I missing something here?

Believe you are looking for self.setResult(cam)

Set the value of the result to be returned by the command.

Name:	setResult(value)
Parameters:	value - bool, int, float, string, sequence of numerics or sequence of strings
Returns:	None
Description:	Set the value of the result to be returned by the command.

In Maya API 2.0  setResult() always returns a list to caller.

In python command I have self.setResult(0.5)

Then I call from mel script  I receive [0.5] 

$res=`getCustomPaintValue -1 4522`;
print("------- getCustomPaintValue1: " + $res + "\n");

I console I have error:

// Error: print("------- getCustomPaintValue1: " + $res + "\n");
// Error: Line 2.47: Illegal operation "+" on data of type float[].

I can use $res[0] in this command, but it doesn't work for other calls.

How can I return command result as float not a list?

Thanks.
