The with statement is basically the same as doing:
def button_a():
mygroup = nuke.toNode("Group1")
try:
mygroup.begin()
nuke.nodes.Blur()
some_func_which_errors_sometimes()
finally:
mygroup.end()
That is, always calling ".end()" even if an error occurs. I.e it "cleans
up" after itself.
For example, say you have two unrelated menu commands - one makes a blur
in a group, the other just makes a grade node (nothing at all to do with
the group)
def button_a():
mygroup = nuke.toNode("Group1")
mygroup.begin()
nuke.nodes.Blur()
some_func_which_errors_sometimes()
mygroup.end()
def button_b():
nuke.nodes.Grade()
button_b() # makes Grade node in root, good
button_a() # makes Blur node in group, good, but then errors
button_b() # now makes Grade in group, bad
This happens because "mygroup.end()" never got called, whereas the
"with" statement ensures this happens:
def button_a():
mygroup = nuke.toNode("Group1")
with mygroup:
nuke.nodes.Blur()
some_func_which_errors_sometimes()

Hows the with statement working here? I was always defining group.begin
and end. This looks much more elegant

Betreff: Re: [Nuke-users] create a node outside a grouped gimzo
"with nuke.thisParent():" would be the other way, which would also work
in the (uncommon) case of working inside nested group nodes
