Offline rendering of PlantUML diagrams broken since version newer than 2.9.8

[Bitfummler]

I'm using your extention since years. I love it. I'm rendering all PlantUMLs locally using asciidoc-diagram gem and Graphviz. Everything works untlil version 2.9.8 of your VSC extention.

When I update to a newer version of your VSC extention the rendering of PlantUML diagrams is no longer working, neither in der VSC preview nor in the rendered output artifact (e.g. a PDF document). After downgrade to 2.9.8 everything is working again. All gems, Ruby, Graphwiz are up-to-date.

Asciidoc syntax I'm using:

plantuml::{wsddir}/myDiagram.wsd[format="svg",width=100%,align="center"]

This does not work under multiple Win10 and Win11 machines. I experienced this bug already 2 years ago, have not reported it so far hoping it gets fixed anyways. It looks like nobody else does offline rendering in an environment like mine ;)

We've removed Asciidoctor CLI (Ruby) support in 3.1.0: https://github.com/asciidoctor/asciidoctor-vscode/releases/tag/v3.1.0
VS code is based on Electron/Node.js and we now relies exclusively on Asciidoctor.js to render AsciiDoc documents.

If you want to keep using asciidoctor CLI, it's possible to setup a similar workflow using both the HTML Preview and Run on Save extensions using the following settings.json:

{
    "emeraldwalk.runonsave": {
        "commands": [
            {
                "match": "\\.adoc$",
                "cmd": "asciidoctor ${file}"
            },
        ]
    }
}

You can also setup a workflow outside of VS Code that relies on the asciidoctor CLI.
Alternatively, you can use Asciidoctor.js with Kroki to render diagrams.
