Too much variable in the python console of VSCODE

[ayeteng]

Bug: Notebook Editor, Interactive Window, Editor cells

Steps to cause the bug to occur

1. The python debug console become very complicated with a lot of special variables. (special variable & much more.) How can I hide the unnecessary variable like before? If possible to have a setting parameter in setup.

Actual behavior

New version both 2020.5.80290 & 2020.5.78807

Expected behavior

Old version 2020.4.76186

Your Jupyter and/or Python environment

• VS Code version: 1.45.1

There's a setting for this:

variablePresentation

If you pass:

variablePresentation={
    "all": "hide",
    "protected": "inline",
}

in the launch configuration, it should behave the same way it did previously.

The keys accepted are: special, function, class, protected and all (all sets the default for all the groups available). The valid values are: group, inline, hide, so, you should be able to customize as you'd like (I believe there are plans to set the default in the editor settings and automatically pass it in the launch, but I don't know if VSCode Python caught up with that already).

p.s.: this was actually done due to the following requests (microsoft/ptvsd#763, microsoft/ptvsd#1621).

@karthiknadig I don't think there's anything to do in the backend in this case, still, I'm leaving it open for you to decide whether something should still be done in the client/docs.

/cc @rchiodo Let me know of we should transfer this back to extension. Or do we need any additional features here.

The variablePresentation setting only seems to hide some of the special variables and function variables. Is there any way to hide all of them?

[int19h]

If you expand those groups, what are the variables under them? Or does it just show the empty group?

[JeremyDalby]

Inside "special variables", it show the special variables of the object's class, and inside "function variables", it shows the object's class methods. In some cases they seems to be infinitely expandable.

@JeremyDalby

The problem in the example is that:

      "variablePresentation": {
        "all": "hide",
        "protected": "inline"
      }

needs to be added inside the Hockey Team Script python launch (the example shows it added as a separate item which is not supported).

Maybe the idea was using it as a template? (if that's the case, this is already reported at: microsoft/vscode-python-debugger#165).

Note that variablePresentation will appear underlined with yellow because it's not declared in package.json in vscode-python (but debugpy should understand it anyways).
