command line output of a node

[Arman Eshaghi]

Hi,

I'm wondering whether there is a way to get command line output of a given node inside a workflow? something similar to function.cmdline() that outputs the command line when dealing with interfaces outside workflows. 

All the best,

Arman

hi arman,

this is only possible after the node has received all it's inputs. it's saved in a file called command.txt in each node's working directory and also in it's provenance trail.

one thing we have contemplated augmenting is to hack the traits code to not raise an error when a required input is missing, but replace it with a string "$VARIABLE_NAME". this way would could potentially generate command lines without running the node.

cheers,

satra
