PlantUML Preview will be launched with Alt + D even for non-Diagram files

[koara-local]

Hello. Thank you for a useful plugin.

Can I restrict PlantUML Preview startup to diagram files only?

For example in Python PlantUML Preview will be launched with Alt + D.

Thank you.

Do you mean that you can write diagrams in comments? If so, I'm sorry.

Yes. I've been thinking about this behavior for a while, I ever disabled for non-diagram document, but enabled it at last. The reason is just as you said, and this is also how plantuml.jar behaves.

Maybe, I should add a setting, leave it to user to decide?

[qjebbs]

Maybe a better way. When alt-D trigged,:
First, I detect if any diagram at cursor. If yes, preview shows.
If not, I detect if any diagrams in document. If yes, preview still shows, but prompt no valid diagram here. If not, nothing happens.

No setting, not annoying..

It is a very good idea if it can be implemented!
I understand that this is the specification, so I will close this Issue.
thank you for your answer.
