Go - go vet的用法

go vet介绍

Vet examines Go source code and reports suspicious constructs, such as
Printf calls whose arguments do not align with the format string. Vet uses
heuristics that do not guarantee all reports are genuine problems, but it
can find errors not caught by the compilers.

Vet is normally invoked through the go command. This command vets the
package in the current directory:

    go vet

whereas this one vets the packages whose path is provided:

    go vet my/project/...
    

文档中可以了解到，go vet命令可以用来检测错误。

╭─ben at MacBook Pro in ~/go/src/github.com/goinaction/code/chapter3/tmp on master✘✘✘ 2021/08/29 - 15:28:58

import "fmt"

func main() {
        fmt.Printf("The quick brown fox jumped over lazy dogs", 3.14)
}

./go_vet.go:7:19: Printf call has arguments but no formatting directives

后记

保持一个良好的习惯：在提交到仓库之前，最好要运行对你的code base执行go vet扫错。
