How to use Golang jump function in VSCode

Foreword:

With the popularity of Golang language, there are more and more related development tools, and VSCode, as a lightweight open source cross-platform editor, has gradually become the first choice for Golang language developers .

VSCode has a rich plug-in ecosystem, making Golang development easier and more efficient, such as plug-ins, Linters, Debuggers, etc. of the Go language itself. Among them, its most important point is its jump to definition function. This article will start with this important function of jump to definition and introduce how to use Golang in VSCode.

Jump to definition means that in a program, when you click or hover on the name of a variable, function or method, it will jump to the location defined by the name. This function is very practical on VSCode and can facilitate us to view the required code.

So how to implement jump to definition in Golang language?

• If you use module to manage the project, you need to set go.alternateTools to gopls in the settings to use the jump function correctly.

Summary:

Golang language is very practical in the development of VSCode editor. Its jump to definition function accelerates our development efficiency. The above is the entire content of this article, I believe it will be helpful to you.
