Trying to set up an interface for a user.
On the parameter interface I have:
1) a parameter set up to retrieve a directory, example:
D:/MEGASCANS_LIBRARY/Downloaded/surface/ground_forest_vlzjadflw/

2) A multi string python expression that strips everything but the last phrase: vlzjadflw, it is a function that can be called via kwargs.


import hou
import os

def strip_dir_call(node):
# Get the current node
node = hou.pwd()

# Get the parameter (channel) object
parm = node.parm("mat_2_dir")

# Get the value of the parameter
value = parm.eval() if parm is not None else ""

# Extract the last folder name from the evaluated value
last_folder = os.path.basename(os.path.normpath(value))

# Split the last folder by underscore and get the last segment
last_phrase = last_folder.split('_')

# Print the last phrase
print(last_phrase)

# Call the function

strip_dir_call(kwargs)



3) This expression is being called on by another parameter celled execute, which is a simple toggle. When I look at the python console I can see the result that I am hoping for.

vlzjadflw
vlzjadflw
vlzjadflw


The issue is, I want to use this returned value elswhere, ideally as a relative reference in a file name path in a separate node. I'm not finding a logical way to do this last step though. H

Any help would be appreciated. Thank you!

So I figured it out--
I made some changes to the pythons script:
the mains script now saves the value result as a new string parameter

i have this script running as a callback script whenever the user changes the file directory.
The file directory gets stripped. The result is added as the new string value for a parameter, and I can then copy and paste this as a reference where needed!

Woot!
