Howdy,

I’m trying to identify a view in a way that works (i.e. such that the result is unique and doesn’t change) after Sublime Text (or the OS, for that matter) is restarted.

At first I thought some combination of view.window().id() and view.id() or view.buffer_id() could serve that purpose, but it looks like they aren’t persistent.

On the other hand, I’d prefer not to rely on view.file_name() or view.name() because they are both potentially ambiguous and/or not present.

What is the right way to do this, then?

Thank you,
Alvaro

view.id() is newly created on each restart.

A way to reliably and uniquely reference views across restarts is to look at their index and their group, using window.get_view_index(view). Of course, this only holds true if the latest indices you saved are still correct and the user did not re-arrange tabs.

Another idea is to store a custom setting, preferrably time-dependent like a uuid4, in each view’s settings storage. Example: view.settings().set("custom_id", uuid.uuid4())

Yes, this looks like the most reliable way, thanks. Why is it being time-dependent important—to minimize collisions?

Yes, it’s probably the easiest way to create a truly unique identifier.
