Send custom commands to gbd

[ilnerdchuck]

Hi I'm building a modified version of this extension to debug a didactic kernel.

I´ve been able to connect the VSCode integrated debugger+cpptools with the following configurations:

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch nmd",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/sistema",
            "cwd": "${workspaceFolder}",
            "miDebuggerPath": "gdb",
            "stopAtEntry": true,
            "preLaunchTask": "run",
            "setupCommands": [
                {"text": "cd ${workspaceFolder}"},
                {
                    "text": "source .gdbinit",
                    "ignoreFailures": true
                },           
            ],
        }
    ]
}

task.json

{
    "tasks": [
        {
            "label": "Compila il nucleo multiprogrammato",
            "type": "shell",
            "command": "compile",
            "options": {},
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build",
            "presentation": {
                "echo": true,
                "reveal": "always",
                "focus": false,
                "panel": "shared",
                "showReuseMessage": false,
                "clear": true
            }
        },
        {
            "label": "Esegui il multiprogrammato",
            "type": "shell",
            "command": "boot",
            "options": {},
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "test",
                "isDefault": true
            }
        },
        {
            "label": "run",
            "type": "shell",
            "isBackground": true,
            "command": "boot -g",
            "dependsOn": "Compila il nucleo multiprogrammato",
            "problemMatcher": [
                {
                    "pattern": [
                        {
                            "regexp": ".",
                            "file": 1,
                            "location": 2,
                            "message": 3
                        }
                    ],
                    "background": {
                        "activeOnStart": true,
                        "beginsPattern": "INF",
                        "endsPattern": "."
                    }
                }
            ]
        },
        {
            "label": "run_debug",
            "dependsOrder": "sequence",
            "dependsOn": [
                "compile_nmd",
                "run"
            ]
        }
    ],
    "version": "2.0.0"
}

I´d also like to add custom functionalities to the debugger´s UI, like showing some custom variables, list of the current kernel processes or execute other gdb commands besides the basic ones. I'm scrolling trough the code but i don't seem to find any clue where any of the commands are created and then executed. Do you know where i can find them?

My idea is to add buttons and lists of what i need in the VSCode right sidebar, for testing I can also use a command from the command palette to launch the gdb command and output all in the debug console.
