vWatch64 VS delve

Where's the error at? Did you try running it with vWatch64 and seeing what happens?

It’s awesome to use the powerful DELVE debugger for GO inside Visual Studio Code when you build a GO Operator. 🙂

dap.adapters.go = function(callback, _) local stdout = vim.loop.new_pipe(false) local handle local pid_or_err local port = 38697 local opts = { stdio = { nil, stdout }, args = { "dap", "-l", "127.0.0.1:" .. port }, detached = true, } handle, pid_or_err = vim.loop.spawn("dlv", opts, function(code) stdout:close() handle:close() if code ~= 0 then print("dlv exited with code", code) end end) assert(handle, "Error running dlv: " .. tostring(pid_or_err)) stdout:read_start(function(err, chunk) assert(not err, err) if chunk then vim.schedule(function() require("dap.repl").append(chunk) end) end end) -- Wait for delve to start vim.defer_fn(function() callback { type = "server", host = "127.0.0.1", port = port } end, 100) end -- https://github.com/go-delve/delve/blob/master/Documentation/usage/dlv_dap.md dap.configurations.go = { { type = "go", name = "Debug", request = "launch", program = "${file}", }, { type = "go", name = "Debug test", -- configuration for debugging test files request = "launch", mode = "test", program = "${file}", }, -- works with go.mod packages and sub packages { type = "go", name = "Debug test (go.mod)", request = "launch", mode = "test", program = "./${relativeFileDirname}", }, } ```

I’ve found Delve (debugging tool) quite useful for Emacs. It uses the plugin from VS Code, so you might be halfway there already? Figure out what you need to configure in Emacs for debugging here.

In this article we are going to see how to debug Go (Golang) programs using Delve. Delve is a third-party debugger for the Go programming language and it’s available on github https://github.com/go-delve/delve. It’s a valid alternative to the GDB golang debugger (https://golang.org/doc/gdb) as it’s more feature rich as mentioned in the official Go GDB website

For Go, Delve is pretty popular.

I mean delve does do that, similar to gdb: https://github.com/go-delve/delve/blob/master/Documentation/cli/README.md

Delve 1.8.0 is out now. I can't wait until tomorrow, so I'll be unwrapping this :-) Thanks Derek, very much appreciated! https://github.com/go-delve/delve/releases/tag/v1.8.0

I see this: https://github.com/go-delve/delve/pull/2703

Go also has pretty good out of the box profiling (pprof[0]) and third-party runtime debugging (delv[1]) that can be used both remotely and local.

These tools also have decent editor integration and can be use hand in hand:

Initially there were some issues with delve (and there still are different ones e.g. https://github.com/go-delve/delve/issues/2277). But other that it has been fine.
