Nuke and Tcl - Intro
Nuke is entirely tcl
based, which means that almost anything you can do with the tcl
scripting language you can use to drive, manipulate and create Nuke
scripts.
To enter tcl code within
Nuke you can simply use the terminal that you used to start the
application from. This is the reason I never start Nuke as a
backgound process (i.e. "nuke &") which would prevent
the shell from turning into a tcl console.
One thing to keep in mind
when using the terminal: backspace is "ctrl+h". Alternatively you can
bring up the command panel by hitting "x" or going to "File/TCL
command...".
In addition to native tcl
commands there is a variety of Nuke specific commands that make it
easier to do so.
For example:
- "selected_nodes"
will return all node ID's that are currently selected in the DAG.
This makes it easy to modify a large number of nodes at once.
- plugins prints
all plugins currently loaded.
- plugin_path
prints all plugin paths that Nuke is currently sourcing
Type these commands into
the terminal or the command panel and see what it spits out.
