Hi Gabriel,

 

Thanks for the reply – I’m very interested!

 

The file you attached like the output I would be looking for.

 

 

Thanks again for reaching out,

You don't often get email from gabriel.desmarchelier at cea.fr. Learn why this is important

Hello,

On our side, we've developed a script that uses tree-sitter-epics (https://github.com/epics-extensions/tree-sitter-epics) to parse the SNL and build a Mermaid diagram from it.

It's not very UML-compliant but it has a convenient option that allows the diagram to include all statements found in state entries and transitions. I've attached an example.

Let me know if you are interested, since it's not publicly available at the moment.

Best regards,

Gabriel
