Remove user added parms: Python

[stevegh]

I have searched the docs high and low and cannot seem to find a way to remove a parm/parmTuple using python. The removeSpareParmFolder method wants an empty folder, so how does one empty it?

Clockwork, as soon as I post the question I find the answer->

removeSpareParmTuple

Sorry guys!

Ok now the real question. I am putting together a simple proof of concept for adding and removing shader patterns using python, and so far so good, right until I get to the removing part. Right now I am looping through the parm tuples in the previously created folder, and removing them with removeSpareParmTuple as follows:

    for i in node.parmTuplesInFolder((folder, )):
	    node.removeSpareParmTuple(i)
[/CODE]

It removes some of the parameters but then throws this error:

[CODE]
Error running callback:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "opdef:/Shop/pythonHda02?PythonModule", line 50, in deleteFolder
File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.533/houdini/python2.6libs\hou.py", line 48221, in __len__
return _hou.ParmTuple___len__(*args)
ObjectWasDeleted: Attempt to access an object that no longer exists in Houdini.
[/CODE]

The docs say:

This method is deprecated in favor of setParmTemplateGroup.

but I fail to see how to remove parms with this method.

Any ideas on why I am getting that error and/or how to use this preferred method?

Thanks!

After more digging I have figured it out. I will post results later for anyone who is curious.
