Allow user to triggger diagram refresh

[kopach]

Please, add support to refresh / regenerate diagram on code change.
Thanks

I have no plans to implement this, but I can see how that would be usefull and would accept a pull request implementing this. Will keep this open for anyone who interested to pick up this work.

The challenge here is to detect the code change. There is no way to subscribe to such event as far as I'm aware, so it would have to be a loop polling confluence API. Another issue with that is confluence API caches the response and changes are not propagated instantly.

Hi @DanielHreben
Maybe I’m missing an existing feature, so please correct me if that’s the case.

For my use case, automatic refresh is not strictly required - a manual refresh would be sufficient. For example:

• A Refresh button in the diagram viewer
• Re-rendering when clicking Edit
• A refresh option in the popup where the diagram is associated with the code

Currently, the only way I’ve found to force regeneration is to select another diagram and then switch back. And if the page contains only one diagram, I have to remove the image and add it again to trigger re-generation, which is quite cumbersome.

A simple manual refresh mechanism would already significantly improve the workflow and should be much simpler to implement than auto-refresh

Ah, I see. I typically just refresh the page. Yes, that would be simpler; however, the same confluence API response caching concerns apply. I'd be ok to accept this change as well.
