[Feature Request]: ability to resolve structure global structure members on mouse-hover (VSC-1584)

[bryghtlabs-richard]

Is your feature request related to a problem? Please describe.
Yes - when I hover the mouse over a structure's member, it shows me the type(which is nice), but often I actually want to see the data inside the structure.

Example structure definition in header:

typedef struct {
  uint8_t AIFrom;
  uint8_t AITo;
}moveVar;

Example usage site:

extern moveVar moveStatus;

void func(){
  clearChessLEDs();
  convertSendLEDData();
  sequenceAILights(moveStatus.AIFrom, moveStatus.AITo);
}

Hovering on moveStatus.AIFrom shows:

Describe the solution you'd like
I'd like ESP-IDF VSCode to display the structure member variable's value instead, or in addition to, the type. Ideally, the same way that ESP-IDF VSCode displays structure member variables values when allocated on the stack.

Describe alternatives you've considered
I can add each global variable to the watch window, but it's quite time consuming.

Unfortunately this a Language extension feature and our extension doesn't implement this yet. In our documentation we suggest users either Microsoft C/C++ extension or Clang extension for language support. It might be best to post a feature request in their respective GitHub repositories.

Thanks @brianignacio5 , I've mentioned it in the Microsoft C/C++ extension repo. We can close this if preferred.

Some follow up questions about your use case @bryghtlabs-richard

1. Which debug configuration are you using ? I mean how does launch.json looks like?

2. Does this happens only when you are debugging or also when you just hovering on the source code file ?

I just want to know since a user replied to you in the cpptools repository that is related to debugging, but it is my understanding that hover definitions are handled by the language extension so I'm not sure how is related to debugging.

@brianignacio5 , here's my launch.json:

{
  "configurations": [
    {
      "type": "gdbtarget",
      "request": "attach",
      "name": "Eclipse CDT GDB Adapter",
      "initCommands": [
        "set remote hardware-watchpoint-limit 1",
        "mon reset halt",
        "maintenance flush register-cache",
        "thb app_main",
        "source ${workspaceFolder}/build/prefix_map_gdbinit"
      ]
    },
    {
      "type": "espidf",
      "name": "Launch",
      "request": "launch"
    }
  ]
}

Does this happens only when you are debugging or also when you just hovering on the source code file ?

It happens when I'm debugging. I think showing the type would be reasonable when hovering when not in debugging.
