[FEATURES] Graphviz / Mermaid integration

[pcamelio]

Hi guys,

Being able to add Graphviz / Mermaid like diagrams would be a nice improvement for the H+M.

Best regards

Hi Philippe,

Thanks for your request, which I've moved to the Wish List section as it's more relevant there. This is the first request we've ever received for this format, so although it will go on the Wish List I can't promise whether it will be implemented in the short term.

I've never heard about this file format. Do you have an example, that you could email to support?

Help+Manual 9 comes with a small generic plugin DLL (ECIMPZIP.DLL) that can read any zip-based format. The only thing hard-coded in this DLL is the list of file extensions, which can easily be extended. It was introduced for SnagIt files. Unfortunately, SnagIt doesn't include a full-size preview, but a smaller version. So, if Graphviz saves diagrams as zip archive and includes a preview image inside (which is quite common), we can most probably read it. Without a simple file format or without a preview, it is going to be very difficult to decode a custom image format.

Hi
It is not a file format like PNG or JPEG.
It is more like the way you insert an equation

Mermaid is extensively used in GitHub / Gitlab etc .. to add diagram in the README.md file and is JS bases
GraphiViz is older
You can find details here:

As I can not evaluate the cost of development, it is just a wish
