Recompute after cell update

[turiot]

Hello, following our exchange on reddit, I think it's a very hard task to detect variables updates, for instance :

    var liste = new ArrayList<String>();
    var x = "x";
    liste.add(x);
    liste.get(0).toUpperCase();

    void method(Point point) {
       point.x = 5;
    }
    var p = new Point(10, 20);
    method(p);  

    method in a jar not analyzed by jshell

Using a "deepHashCode" to compare vars after snippet execution can be a solution, but with size limitations (huge collections or arrays).

Another option is to recompute the whole notebook, excepting snippets which previous executions was time consuming, asking advice to the user. This solution overlaps the restore of a saved notebook.

Maybe these options can coexist and be chosen by the user, according to his usage profile (java learning, api testing, data science, ...)

Hey,

I'm not sure to understand the example. Is this something that is not working as expected in the current implementation?

If not I'll move this to discussions.

Sorry, discussions was actually the place to post.
