Nuke - Print out AppendClip Inputs

AppendClip node is useful for anything like viewing a bunch of shots after each other. I used it to check out different versions of FumeFX simulations. Only one thing I had to find out: how to print the current version (version of the file sequence) of the effect out to the screen. Using a Text node we could utilize python commands within the message field. So the node graph is something like this:

And the python command (it called from TCL):


[python {nuke.thisNode().metadata()['input/filename'].split('/')[-1]}]

I don't know much about TCL but I could figure it out how it would look like in TCL syntax:

[lindex [split [metadata input/filename] {/}] end] 

It reads the node's metadata which is passed through by the current read node. The metadata holds the input/filename key and that is what we are looking for. nuke.thisNode is the node where the comman is called (the Text node in this case). Further information is here. In TCL it seems there is a basic metadata command.
