I really don't understand how should I refer to an operator (HDA) from within scripts inside it (both from “Extra Files” and “Scripts” section).

When I call PythonModule's function I have to send it reference by hand since I didn't find any other solution:

hou.pwd().hdaModule().main(hou.pwd().path())

but this is crazy of course! There must be a “normal” way. This also doesn't work with “onInputChanged” script as I can't send any variable like before.

In both cases hou.pwd() returns context carrying operator (/out) not a operator itself.

thanks for help.

In a callback script on an hda you can do something like

hou.node('.')

to refer to ‘self’…I think that is what you are looking for.

hmm… not really, this was the first thing I've checked.
Unfortunately this returns /out instead of /out/my_operator

I've already found my old post on the same subject… strange but few months ago I was struggling with the same topic.

I was told that in case of hscript, a script in hdaModule (onCreate for example) gets reference by argument $arg1.
But I don't know how to send to python…

still looking,
thanks,
sy.

hm.
I tried this at home:
a button that executes this script:
hou.ui.displayMessage(str(hou.pwd()) + “\n” + str(hou.node(“.”)))
And both point to the correct node.

Just yesterday I used hou.pwd() in my callbackscript and it worked just fine.

you,re right. Callback script is not a problem. You can send it attribute.
Try to reference like this in “onCreate” or “onInputChanged” script .
Well, can't be done

Since python event handlers are currently not supported in 9, using $arg1 to get the path of the new node is the correct thing to do. You could do something like this.

python -c “hou.node('$arg1').hdaModule().main('$arg1')”

Note that Python event handlers are supported in later versions of 9.0. The node is available via kwargs. So it would be something like:

node = hou.node(kwargs)
node.hdaModule().main(node)

Oops. I forgot they were back ported

kwargs returns a node object so it should be

node = kwargs
node.hdaModule().main(node)

O! Thank you!

happy, happy I am.

cheers,
