Integrate mermaid charts

[jamesburton]

Given that GitHub and many other git providers support mermaid charts within their markdown it becomes more important to support this format to be a viable choice of standalone editor.

I was wondering the same thing for PlantUML. In either case, I was wondering how it would look in the UI?

Is there support for mermaid, in any way with ghostwriter?

This is probably a bigger thing to ask for than it looks. Mermaid, to my knowledge, is a Javascript library, so you'd need to either port it to C++ and Qt to make it work with what Ghostwriter already has, or implement some kind of web renderer with Javascript support, at which point you're basically reinventing Electron. Web-based programs like GitHub's editor get away with it because they're already written in Javascript, so integrating Mermaid is easy for them. Not so much for a native desktop app.

Hi there,

Thank you for your response. I found out that as Ghostwriter uses pandoc to render and also offers the feature to pass extra parameters that one can simply put '-Fmermaid-filter' in the extra parameters and Ghostwriter will tell Pandoc to filter the output through mermaid.

That will work just fine.
