[hyangah]

From microsoft/vscode-go#3169

@lggomez has pending PR(#89) to implement this feature.
With example configuration:

{
            "name": "core:Launch",
            "debugServer": 4711,
            "type": "go",
            "request": "launch",
            "mode": "core",
            "program": "${workspaceRoot}/main/main.go",
            "env": {},
            "args": [],
            "dlvLoadConfig": {
                "followPointers": true,
                "maxVariableRecurse": 1,
                "maxStringLen": 5,
                "maxArrayValues": 5,
                "maxStructFields": -1
            },
            "backend": "coredump",
            "executable": "${workspaceRoot}/main/helloworldmodules",
            "coreDumpDirectory": "pathtodump...",
            "trace": "verbose"
        },

Hello @hyangah, I am an happy user of vscode-go. I would like to ask to reconsider the priority of this feature, I think it would be quite useful. Thanks for all the work of the vscode-go team :-)

This feature is now available using the following in your launch.json

"request": "launch",
"mode": "core",
"program":"path/to/executable",
"coreFilePath":"path/to/coredump",

Thank you @lggomez.

@marco-m-pix4d Please let us know if it is not working for you. Thank you.
