behave-graph VS Magnit.NodeGraph

How does this compare to the open source behave-graph library?

Is Luna based on behave-graph?

I enjoyed reading this. I knew of quartz composer but I never did anything with it.

I love visual tools and I think they are underutilized today. I cut my teeth in ~2005 with Houdini[0] and Fusion[1] which are both heavily graph / node based (and procedural).

Most recently I have been rekindling my love for visual programming and flow based programming and plan to spend some time in January and February doing more research around flow based programming for infrastructure management.

I plan to get this sort of info published on my website which I have neglected for half a decade or more but if you are interested in visual programming you might enjoy checking these out:

Fun fact, a lot of it is open source, just not where you would expect it. During the creation of Clara.io I created over 200 PRs to Three.js:

https://github.com/mrdoob/three.js/pulls?q=is%3Apr+author%3A...

The problem with open sourcing it wholesale at this point is a challenge because parts of the tech stack became parts of Threekit.com. Threekit.com is VC funded and an ongoing business operation.

I do what I can with open source still, see:

Don't forget behave-graph/behave-flow, the Unreal Engine Blueprints / Unity Visual Script like interaction/behavior system:

Oh sweet! I was in the middle of building my own version of a node-graph component (ref: https://github.com/catapart/Magnit.NodeGraph), but the `canvas.js` implementation from this JsonCanvas repo is exactly what I was trying to build. I really, really like how elegantly uncomplex it is. Could not have been more exactly what I was looking for. So thanks for this!

As far as the spec, I don't really like the idea of forcing well-known types for the nodes. A generic spec should allow for entirely generic nodes that can represent themselves to consuming functions with a 'type' property as a key, as well as arbitrary data types linked to arbitrary nodes. For instance: one of my use cases is an 'addition' node, which would take two number values and produce a number value. This node would also use an entrance execution pin as well as an exit execution pin.

If the spec were to include a 'pin' data type and capture the type keys and labels for pins, those pins could be stored as a list on the node. Then, the type property could just tell the executing context how to route the node data and the pin properties would bring type safety to the functional inputs passed to the mapped function.

Anyway, I assume all of that is out of scope for initial offerings, but that's my two cents on a generalized node spec. Regardless, thanks again for the sweet, simplistic node graph implementation!

People did; you didn't.

> Ergo, vis-a-vi have you ever actually tried making a graph that is rearranging itself while you're using it?

No one said anything about "while you're using it". Linters don't fuck up your text as you type it. It's a utility like anything else. And, YES, I have built a working version of one. It doesn't use machine learning/tensors at all, and it's a fucking nightmare to develop. I can see exactly where those things would help me. It's too abstract, to you, to understand? That's a shame! But other people seem to get it, so if you are having trouble, maybe try approaching your ignorance with openness and curiosity instead of cynicism and trivialization ('uncross some lines').

If you want to know how much time I've spent working on node edge graphs, you wouldn't believe me. But I can at least point you to the start of the web-component version I'm porting: https://github.com/catapart/Magnit.NodeGraph

Shameless plug time! I've been working on something like this as a custom web component with no dependencies: https://github.com/catapart/Magnit.NodeGraph

Not the most feature rich - I'm developing it for a single project, so that's project's needs come first. But it's rudimentary enough to start from if you're looking to build your own, and it's simple enough to customize if it already does what you need.
