The simplest way to do this would probably be to use Nuke's built-in
serialization via nuke.nodeCopy, as opposed to trying to roll your own using
Node.writeKnobs() and some fancy formatting. Unfortunately, this function
only accepts strings as arguments, rather than file-like Python objects
(side note: in thinking this one over, I actually just submitted a feature
request for this...).
As a workaround, you can use a tempfile.NamedTemporaryFile instance to get
this done:
from __future__ import with_statement
import tempfile
with tempfile.NamedTemporaryFile() as fd:
nuke.nodeCopy(fd)
result = fd.read()
The temp file will get deleted when the with block exits (as part of its
close() method), so you shouldn't have to worry about lots of temporary
files showing up on your machine.
Hope this helps.

Subject: [Nuke-python] derive TCL node structure from selected nodes?
hi everyone!
i need to somehow derive the nodes and their connectivity data (ie:
set & push commands), from a list of selected nuke node objects,
preferably in python.
here is an example of the desired derived data:
myData = """
set n11111 [stack 0]
Grade {
name Grade1
selected true
xpos 0
ypos 0
}
push $n11111
Grade {
name Grade2
xpos 100
ypos 100
}
Merge2 {
inputs 2
name Merge1
xpos 200
ypos 200
}
"""
i feel like this is possible to get somehow because Ctrl+C derives
this data and puts it on the clipboard natively in nuke. nuke also
must use something like this in it's "export nodes as script"
function.
so, anyone know how to do this?
thanks for any advice!
