Specifying substitutionPath

[ldelossa]

Hello,

I'm attempting to use nvim-dap in place of VSCode debugging.

We use a remote delve instance in a kind cluster. In order to do this we need to substitute the paths from the local host to the paths in the remote debugger instance.

In VSCode launch configuration it looks like this:

    "configurations": [
		{
			"name": "Attach to kind-control-plane-1",
			"type": "go",
			"request": "attach",
			"mode": "remote",
			"remotePath": "",
			"port":23401,
			"host":"127.0.0.1",
			"showLog": true,
			"trace": "log",
			"logOutput": "rpc",
			"substitutePath": [{"from": "${workspaceFolder}", "to": "/go/src/github.com/cilium/cilium"}],
		},

And this results in VSCode sending that field in the initialization "attach" request.

I'm trying something similar with nvim-dap:

dap.adapters.cilium_kind_control_plane_1 = {
    type = "server",
    host = "127.0.0.1",
    port = 23401,
}
dap.adapters.cilium_kind_worker_1 = {
    type = "server",
    host = "127.0.0.1",
    port = 23411
}
dap.adapters.cilium_kind_worker_2 = {
    type = "server",
    host = "127.0.0.1",
    port = 23412
}
dap.adapters.cilium_kind_worker_1 = {
    type = "server",
    host = "127.0.0.1",
    port = 23411
}
dap.configurations.go = {
    {
        type = "cilium_kind_control_plane_1",
        request = "attach",
        name = "Attach to kind-control-plane-1",
        mode = "remote",
        substitutePath = {
            {
                from = "${workspaceFolder}",
                to = "/go/src/github.com/cilium/cilium"
            }
        }
    },
    {
        type = "cilium_kind_worker_1",
        request = "attach",
        name = "Attach to kind-worker-1",
        mode = "remote",
        substitutePath = {
            {
                from = "${workspaceFolder}",
                to = "/go/src/github.com/cilium/cilium"
            }
        }
    },
    {
        type = "cilium_kind_worker_2",
        request = "attach",
        name = "Attach to kind-worker-2",
        mode = "remote",
        substitutePath = {
            {
                from = "${workspaceFolder}",
                to = "/go/src/github.com/cilium/cilium"
            }
        }
    }
}

However, when creating a break point I ge ta response that the file cannot be found and the file being displayed in the error is specifying the local path.

NVM, this works, had some errors on my end.

@ldelossa I have exact same issue.
was it a path error? how did you fix it?
Im looking for a proper way to make it.
also wonder how jetbrains does it automatically without asking for a user input

[dennypenta]

ok, I cracked it, thanks.
my issue was I set a breakpoint right inside a go module and it requires an additional path substitution.
took me a whole day
