Because the expression parser only handles floating-point values (i.e. no strings, ints, etc). However, the expression parser is still just an incarnation of TCL...
Why are you so intent on avoiding TCL? -Nathan From: Brandon Harris Sent: Monday, May 02, 2011 10:01 AM To: Nuke Python discussion Subject: Re: [Nuke-python] Python in file paths And that is something I would like to avoid. Is this even possible without using TCL? I can setup expressions for knobs elsewhere using the this.knob, parent.knob, root.knob, why is a file path handled differently? Brandon L.

You can then set the file path to be: [python myFunc()] And then make sure that myFunc() returns a string...

Is there a pythonic way of accomplishing this? Something along the lines of /my/path/to/{this.name}/{parent.someKnob}. The ability to have expression based paths would be very nice and I would prefer not to have tcl in my current pipeline. Brandon L.
