At the end I decided to rewrite the plugin completely and here is the repository I created:
I called the plugin PlantUML2 and I implemented all the feature requested for the original plugin:
- @th-ros Feature Request: save diagram as image · Issue #7 · uphy/joplin-plantuml-plugin · GitHub
- @andi0b PlantUML blocks don't switch editor to monospace font · Issue #5 · uphy/joplin-plantuml-plugin · GitHub
- plugin causes a crash · Issue #3 · uphy/joplin-plantuml-plugin · GitHub
- @renestalder Data is sent unencyrpted to plantuml.com · Issue #2 · uphy/joplin-plantuml-plugin · GitHub
- @renestalder How does the plugin work? · Issue #1 · uphy/joplin-plantuml-plugin · GitHub
