Getting cm editor instance and swapping doc

[UhMarco]

I've seen previous, similar questions but I'm not sure they're providing what I'm after. I'd like an instance of code mirror where I can run methods such as cm.getDoc() and cm.swapDoc() as seen in the documentation here:

Could anyone clear this up for me?

I've realised I was looking at version 5 documentation. What's the version 6 equivalent?

For some more context: I'm working on a note taking app and would like a different instance for each note opened, for history and similar purposes. I believe .swapDoc() would have been a solution in v5.

Thanks. What is the equivalent of .swapDoc() in the latest version?

[jaywcjlove]

@UhMarco You need to check the CM 6 documentation for this.

I've been looking but haven't found anything that looks similar...

@jaywcjlove Perhaps if I give some more context you'll be able to point me in the right direction. The way I'm currently swapping between notes is just by setting the content. If I perform an undo command, the content goes back to the previous note. From my understand swapDoc() would have been what I needed to prevent this from happening and also keep other notes in memory. Is there an equivalent for version 6? I have read through the docs you sent and have not seen something directly similar.

@UhMarco Possibility to ask questions to the CM author.
