vscode.debug API should provide the current thread/stack frame ids

[gregg-miskelly]

Currently the vscode.debug API provides a way to send custom events to debug adapters. But it is missing one fairly important thing - there is no way to know what the current thread id / frame id is. So a debug adapter could maybe guess. But it feels like there should really be a way to query this.

Hi @hediet, I noticed you self-assigned this recently. I was wondering, is there any kind of plan as to what an eventual API on this might look like? I also wanted to check that this feature request is the same one discussed on a different repo here. Is the idea here to allow access to the ID of the "current" stack frame in the sense of the one that the user has selected in the VS Code debugger view in the sidebar?

It is unclear if this ever gets implemented, but I have a personal interest in it, thus I assigned it to myself to keep track of it.

@weinand Will you accept a PR for this?
I have the code here.
I tried to keep it smallest and coherent with existing code as possible.

[weinand]

@elazarcoh In principle we are willing to accept a PR. But since this is extension API it has to go through our extension API review process.
The first thing we need is an API proposal.

[elazarcoh]

is it something I can start? or it is something that is done only internally

@elazarcoh you can start just here.
Please study some existing API items with the "api-proposal" label to learn how API proposals look like.
