Hi Mike,
There's no document for it as far as I know, but the syntax is basically
TCL, with all commands unknown to TCL (e.g. "Grade") being interpreted
as node types, and the lines inside the node types setting knob values.
However, I'd recommend you avoid working with .nk files if at all
possible, as I'm sure you'll come up with all sorts of complications.
If you want to create Nuke scripts from some other sort of scripting
language - e.g., to match the output from a different application, or
just perform an arbitrary set of operations - I'm sure you'd find it a
lot easier to just start up Nuke in terminal mode (nuke -t) and use
Nuke's own commands to create the script as you like it. That way
you'll have access to higher-level commands such as nuke.createNode(),
which will save headaches. If licensing is a worry, it may be useful to
know that terminal mode only uses a render licence.
Of course, all of the above depends on exactly what you're trying to do,
but I definitely think it's worth considering.
Cheers,
- Chris

Not that I've seen or heard of. As far as layout goes, it's basically
a TCL command stack, with serialized knob values. Node inputs are
simply taken from immediate ancestors in the stack.

*Subject:* [Nuke-python] Nuke *.nk File Specification Document
Hi all,
Does a Nuke *.nk File Specification Document, blog post, something
else?...exist which documents how a Nuke script is laid out, how
branches work, etc.
The idea is I could just open up notepad, type a Nuke script, hit save
and it would be fully compliant upon opening in Nuke.
I'm aware of the basic concepts of how a Nuke script is laid out, I'm
just wondering if The Foundry have documented their file format so new
TD's, developers can read up on it:
NODETYPE {
knobName knobValue
knobName "knobValue"
knobName {{curve x#Frame# keyvalue x#Frame# keyvalue}}
}
Thanks,
Mike
