Things I find myself doing
via tcl are:
- Analyzing a script. I.e.
printing info about selected nodes, such as the number of Write nodes
along with their current state (enabled/disables) and their render
order.
- Looping through nodes to
change multiple knob values at once or simply display their available
knobs
- Extending the
functionality of nodes (i.e. make a crop node conform to the current
viewer's roi)
- Creating import/export
functions to communicate with other programs or use external files to
create nodes or animation curves
- Reading a database to
make specific info available in Nuke
- Set script defaults based
on environment variables
etc...
Some standard features and
tools in Nuke are in fact nothing more than tcl scripts so it's a
good idea to look at the default tcl files that ship with Nuke to get
an idea how they work.
Some of these tools are:
- "File/Goto Frame..."
calls goto_frame.tcl
- "File/Buffer Report"
calls cache_report.tcl
- "Edit/Node/Info
viewer" calls infoviewer.tcl
Lastly, the menu.tcl which
can be used to customize Nuke, is another good example for how tcl
can be used in combination with Nuke. I highly recommend getting
familiar with how to set it up, it'll be your best friend when you
want to add and change menus, hotkeys or default values for nodes (check out pages 137-139 in the Nuke_User_Guide.pdf for that)
.
