Plot Nodetree Setup

[Sinasta]

This is not a bug report and please feel free to close it instantly if it is not an appropriate channel to ask this question. I would like to plot my nodetree setup showing the structure and connection of the different nodes for documentation reasons. So the way i am doing this right now is to take multiple screenshots of the nodetree, add them together and remove the background. I kinda feel like there should somehow be a way to export the Tree to a plottet svg graph where each box is labeled with the node name and lines showing the node connections. Is there such a possibility?

a super minimalist nodetree->svg is relatively uncomplicated to make, but the individual node uis are a lot more involved. so. super abstract is easy, but users may not be a fan of it.

we did experiments also drawing nodes as svg from their specs #269 (comment) (several posts..) for docs, but it felt incomplete.

but..

suggests this addon: https://github.com/Yeetus3141/PrintNodes/

here's a sverchok nodetree to svg script using lxml xml elementtree, it allows for exporting the xml prettyprinted / nicely indented. Other than that the api behaves much the same as the python standard library's xml.etree.ElementTree

This is just amazing!

I didn't manage to get "Frames" in the right position yet, but that's about the extent of what can be done with relative simplicity. Drawing the ui of the nodes would require a full blown reverse-engineering of Blender's UILayout api - and that's not going to happen.. at least, i won't be doing it.

I think the Blender NodeFrame's location property is broken at the moment (or maybe i'm being stupid), therefore i compute the bounding box and introduce padding.

It's impossible to get frame location via Python API. That was state by some of Blender developers.

[zeffii]

good. I thought i was losing my mind

gradient noodles.

todo set element colors (sockets, text) via css by setting classes/id.

[zeffii]

uhoh. some degree of UILayout should be possible to wrap..

i'll migrate this to it's own repo.. https://github.com/zeffii/sverchok_to_svg.git
