通常，如何在VIM中“定义”？ 那我怎么用golang呢？

Question

Two part question:

First, when using VIM what process do I take and what keys do I type to "go to definition" or "go to declaration" etc.? This document might be the answer to my question, but I can't get it to work, so I'm unsure. It looks like its merely text matching the string rather than finding the true definition. If I can get this to work, then will I be able to jump outside of the current document to a definition/declaration? Or does this only work within a single document?

Second, how do I make this work specifically with the Go programming language? It sure would be nice to "click" the Client in

clnt := &http.Client{Transport: tr}

And be taken to the actual code that defines an http.Client.

Possible? How?

Answer 1

As you guess, gd (and other commands) is merely text matching, vim don't understand the syntax as it is just a text editor, :h gd will explain how gd works.

Usually, 'go to definition' is brought by using CTRL-] and tag files. A user manual about this topic can be read by :h 29.1.

First you need to generate a tags file for your project, as latest Exuberant Ctags has supported golang (from here), command

cd /path/to/your/project
ctags -f tags -R --fields=+K+a

will do the job.

Second, open vim, by default vim will find tag files under working directory (according to 'tags' option), if the tag file is found successfully, then CTRL-] should works well.

Also check two useful plugins Tagbar and Easytags.
