Thanks guys. So from what you’ve mentioned, I get the impression that script_expand does something like performing a pass on the input array using Nuke’s expression parser to resolve non-TCL references (knob links, 'frame', 'view', etc.) to their actual values, and script_command will actually run it through the TCL (or Python) interpreter?

You'd still get the result as a string, though, so just convert as appropriate if you need the numeric value as a different type.

I’m curious if there’s a way to evaluate a standard Nuke expression (not a TCL script) from a string or char* and return its numeric result, without calling through Python to nuke.expression or something similar.

I tried almost exactly that, but I thought ‘views’ was a list and not a function. ‘len(nuke.views)’ returned an invalid parameter error in the Script Editor. ‘len(nuke.views())’ works like a champ, tho. Thanks for your help, Ivan!

This should work, I think: const char* PyGetViews = "len(nuke.views())"; script_command(PyGetViews,true,true); string views = script_result(true); script_unlock(); // to remove the lock started by script_command Cheers, Ivan On Thu, Jul 5, 2012 at 12:07 PM, Steve3D <nuke-dev-re...@thefoundry.co.uk> wrote: I've been digging through the current documentation this morning, and I can't seem to locate this. I need to know how many views are currently defined in the Project settings. How would I get that from inside a plugin? I'm thinking it should be accessible by executing some Python (using perhaps 'nuke.views' ?) But it's not at all clear what the correct syntax is.
