根据作者的说法：

Golint is a linter for Go source code.

Golint differs from gofmt. Gofmt reformats Go source code, whereas

golint prints out style mistakes.

Golint differs from govet. Govet is concerned with correctness, whereas

golint is concerned with coding style. Golint is in use at Google, and it

seeks to match the accepted style of the open source Go project.

一句话就是Golint用于检查go代码中不够规范的地方。

一、编译及生成可执行程序

1、下载golang 的 lint，下载地址：https://github.com/golang/lint

2、解压文件到$GOPATH/src/github.com/golang/lint

3、到目录$GOPATH/src/github.com/golang/lint/golint中运行go build ./

4、在当前目录有golint的可执行程序

当然，最简单的方式是：

go get github.com/golang/lint
go install github.com/golang/lint

二、执行方式：

golint 文件名或者目录

检查结果如下：

import-dot.go:6:8: should not use dot imports
else.go:11:9: if block ends with a return statement, so drop this else and outdent its block
sort.go:11:1: exported method T.Len should have comment or be unexported
sort.go:20:1: exported method U.Other should have comment or be unexported

从上面输出可以看到，golint对go代码给出的建议。

golint 会检查的内容：

变量名规范

变量的声明，像var str string = "test"，会有警告，应该var str = "test"

大小写问题，大写导出包的要有注释

x += 1 应该 x++
