Attaching editor on existing object

[Michael Tsikerdekis]

I am trying to attach the editor on an element that already has attached the editor.

Specifically, on overleaf, I am trying to attach using ace.edit from an extension's content script on the existing editor.

Content scripts and the main page live in isolated worlds so I cannot access directly the existing ace session. When I use ace.edit on the existing element, I get an error

 Watch out!

I cannot tell if this is an ace editor issue or some other javascript code that generates this error.

If anyone has any other idea on how I can work around this issue please let me know.

If you create a new editor you will break the page. There are ways to run script in page context https://stackoverflow.com/a/9517879 so the only solution is to use one of them and use the env variable added by ace to the dom element to access the existing editor and session.

So basically, only through running a script to access the window variable. Btw, you did mention the env variable is added in the DOM. I have access to the document so would that work?

I think modified properties of dom objects are accessible only in the context where they were modified, so yes, the only way is to use a script in the page.
