Debugging With Vim Go

Although learning VIM can be quite painful, I learned it and now I love it so much I can’t write or code without it.

For example, debugging programs using VIM is not as trivial as clicking on a button like most IDEs.

In this post, I will show some basic commands to use to debug a Go program with vim-go.
