question: how to use ui for (*custom*) python code generation?

[s-light]

hello community,

i would like to experiment with this flow-graph ui embedded in a CircuitPython web-editor.
so my target output are python files.

on my current looking into this package i do not have an idea how to start with this..
for my use-case i can not use a live / play mode -
i think more of a every time a changes is made i regenerate the code -
so i need some kind of code-fragment-generation for every node...
would it be a good idea to just use the onExecute function to append the code-fragment?
(i know i would have to write a a lots of nodes to have all the basic python language parts available..)

or does anybody knows of a visual similar maintained library/framework that has python code generation already implemented?
maybe there is a fundamental other concept / idea how to go about such an idea..

in the end i would love to have both: flow-graph to code | code to flow-graph
so aim also very open to any comments / ideas...

I am not sure if this is helpful for your use case, but I am working on a code => flow-graph. Currently working on the other direction (and is considerably harder IMO).

Node definition begins with at best I can describe as inheritance (not really a thing in golang). You can see an example of this here
https://github.com/EliCDavis/polyform/blob/main/examples/edit-gaussian-splats/main.go#L55

This requires a ton of reflection to then transform it into a node when it comes to javascript, which comes down to a switch statement based on the type of data it's dealing with
https://github.com/EliCDavis/polyform/blob/main/generator/html/js/nodes/node.js#L10

Luckily being in python, you don't really need to deal with reflection, which might make the flow-graph => code aspect easier.

I don't use onExecute ever. I subscribe to node creation/deletion/connection editing.

Thanks EliCDAvis!

that are nice hints and concept points!

do you know of the BlockMirror project?
it does python → blocks (blockly)
they are using

Skulpt: A Python-to-Javascript transpiler. We use it for its parser.

they parse the python to an Abstract Syntax Tree (AST) and from this generate the blocks.
i did not dig deeper in the how all of this works ;-)

for now i have to lay this project idea on ice..
(it is just to complex for me / to much other things needing my attention)
