Custom Functions support?

[taresh18]

Hi, thanks for building this. Its really helpful for quickly iterating changes within conversation flow. I have a few questions:

1. How can I define a custom function? Currently I can only add some condition base on custom python code. This is really inconvenient and unusable if my function is a little complex. I want to have resusable function nodes like db_lookup_tool, transfer_call_tool etc. which I can connect to other nodes easily.

2. How do I define the return value of a function? I want my function to reqturn something which I may want to add to the flow manager state and access in other nodes or add to the chat context.

3. Also, its lacking quite a bit in little QOL things like copying an existing node, dragging the connections which is currently fixed and becomes a mess as soon as flow complexity increases etc.

Hey @taresh18,

thank you for the feedback!
There are some good points to think about.
Currently the function definitions generate something like this:

# TODO: Implement function logic
# Update flow_manager.state as needed
return None, create_xyz_node()

Or, when there's a decision:

"""Handler for xyz function"""
# Execute action (must set 'result' variable)
result = some_function()

# Conditional routing
if result == 1:
  return result, create_node_1_node()
else:
  return result, create_default_node()

You could temporarily exploit the decision panel to include your custom code:

"""Handler for xyz function"""
# Execute action (must set 'result' variable)
flow_manager.state["y"] = await do_something()
        
result = None

return result, create_default_node()

That's more of a hack though and probably not necessarily what you have in mind. If I understand correctly you'd like to create globally available functions through dedicated function nodes and then wire them up from your conversation nodes. You're right that this could become potentially messy to maintain, but I'll think about it a bit.

Regarding QOL improvements: let me track a ticket to add a context menu for nodes which allows duplicating and deleting nodes and keyboard shortcuts.
