Go for Visual Studio Code VS GNU/Emacs go-mode

You have different fields/properties which according to this page you can tweak in your debugging configuration:

Can someone please tell me what I'm doing wrong? I looked at this and even looked at what Go themselves had to say on their VSCode extension page, but neither of these are helping.

It seems that most Go utilities have been submerged into gopls, the LSP server. So a lot of older websites that suggest how to configure go-mode might be outdated, because of the cultural shift away from the unix-ish little, collaborative utilities approach. This means you will need a LSP client -- the Go project has some documentation on that. I'd strongly recommend Eglot, if you are uncertain what to use(0). This page explains how to install gopls with your Go toolchain.

I haven't used Dash, so I don't know the specifics of what it works, but if it works like running pydoc or godoc or whatever Java has inside your text editor, here is a plugin for pydoc inside emacs and here's another for godoc (as part of a larger mode for go). I just tested godoc and it seems to work fine, if a little too basic.

This question makes very little sense to be honest. Try using spacemacs. It has a go language server runner. Otherwise try this https://github.com/dominikh/go-mode.el
