Mermaid export with path walked

[marceloandrader]

Hey, thanks for neuron is super helpful.

I was thinking if the Workflow class can export a mermaid graph, with some styles, saying which nodes have been visited on the execution. Using this https://mermaid.js.org/syntax/flowchart.html#styling-a-node

I can work on this one, if you give me some direction and if it's feasible.

Hi @marceloandrader, Neuron already have a Marmeid exporter:

https://github.com/neuron-core/neuron-ai/blob/2.x/src/Workflow/Exporter/MermaidExporter.php

You can eventually improve it.

You can inject the MarmaidExporter instance into the workflow before calling export:

use NeuronAI\Workflow\Exporter\MermaidExporter;

$workflow = Workflow::make()->addNodes([...]);

// Inject an Exporter class
$workflow->setExporter(new MermaidExporter());

// Draw the workflow graph
echo $workflow->export();

The exporter depends by its own interface ExporterInterface so you are free to improve current components, or implement new ones.

Yeah I'm aware of the exporter, was wondering if you see a way to add some style to nodes that have been visited, like when there is a branch, I want to know which branch was used during th execution. I guess this kind of export will be performed when a StopEvent is emitted.

Never thought about it. You can think about a PR if you will.

Sorry, @ilvalerione but is this a visual representation of the nodes? Could you please point me to where I can read more about it and how to integrate it? I couldn’t find anything like this in the documentation…

[ololoDevs]

Yeeee, i maked it! )))

[ilvalerione]

Yeah! That's a great Workflow!! I should write something about the "Exporter" in the documentation!
