This should definitely be possible, I'll look into it. Your use case is very interesting, looking forward to seeing some geometry script in there!

I gave a talk at BCON last year on the use case if you want to hear me talk more about it: https://www.youtube.com/watch?v=adhTmwYwOiA

I'll hold off on converting anything immediately to see if there is an easy solution, but otherwise I'll go through and start converting them manually probably in like a month or so when I've got some more time to dedicate to it. I also personally find that prototyping functions manually inside of Blender is faster, to then be able to quickly save it out as code for git to read would be great.

I have a prototype for this implemented in #13. Let me know if you have any problems converting more complex node trees.

Ooh very exciting, thanks for the quick turn around. I'll give it a test run and try it out!

I've been playing around with geometry script for some time now, and I love it!
This would be a killer feature for existing geometry node projects, I see that there is already a draft implemented.

Is this still in development? Can I try this somewhere?

@tbscode If you go to this page (or just select the nodes-to-script branch), you should be able to download the addon ZIP. Let me know any issues you run into when converting.

Thanks, jup using this link I could download the current build: https://github.com/carson-katri/geometry-script/archive/refs/heads/nodes-to-script.zip

Though I think I still need some missing commits for the blender 3.5 update ( I'm on 3.6 & linux ).
Currently I'm just getting:

Read prefs: "/home/tim/.config/blender/3.6/config/userpref.blend"

I suppose just cloning this repo to $HOME/.config/blender/3.6/scripts/addons/* should also work, so I'll try merging this locally and test it then.

Yeah got it to work.
Seems to work generally pretty well, so far I saw one issue.
The new Simulation nodes output doesn't seem to be correctly serialized:

paired_output=<bpy_struct, GeometryNodeSimulationOutput("Simulation Output") at 0x7fb804f59988>

Should I report my findings somewhere else, as separate issues?

i think that function (Convert existing node trees to Geometry Script) is useful, When i have an idea, i usually use node trees to validate it. if it work, then i will convert it to python code.
So I'm also looking forward to this feature too
