create argument to Pluto.run to disable autosave

[adannenberg]

I know this has been discussed on Discourse but I'd like to re-raise the subject and present the use-case to justify the proposed change...

I often have the same Dropbox or Google Drive-stored notebook open on both my laptop and my desktop. To avoid losing changes made on the laptop (say), Pluto's autosave requires me to close and re-open the notebook on the desktop before making changes. If I forget to do so then the more current version of the notebook that's on my laptop is lost.

I understand that all of this is really an argument for using git or some other vcs. Yes, I agree. But it would be nice if the simpler workflow of using a cloud-based filesystem could be made less risky by allowing the user to opt out of autosave (which also introduces the risk of losing your work - I get it).

You can use Pluto.run(disable_writing_notebook_files=true) to ask Pluto to never write to any file. This means that nothing you do in this session will be saved to disk ⚠️ (even if our UI says that it is). The only way to persist work is to use the Export button.

Is this what you need?
