go 代碼檢測和測試

1. gofmt
   1. Gofmt formats Go programs. We run gofmt -s on your code
2. go_vet
   1. go vet examines Go source code and reports suspicious constructs, such as Printf calls whose arguments do not align with the format string.
3. gocyclo
   1. https://github.com/fzipp/gocyclo
   2. Gocyclo calculates cyclomatic complexities of functions in Go source code. The cyclomatic complexity of a function is calculated according to the following rules: 1 is the base complexity of a function +1 for each 'if', 'for', 'case', '&&' or '||' Go Report Card warns on functions with cyclomatic complexity > 15.
4. golint
   1. Golint is a linter for Go source code
5. license
   1. Checks whether your project has a LICENSE file.
6. ineffassign
   1. IneffAssign detects ineffectual assignments in Go code.
7. misspell
   1. Misspell Finds commonly misspelled English words
   2. https://github.com/client9/misspell

-X version.BuildTime=${BuildTime} \
-X version.CommitID=${CommitID}"  

@go build ${LDFLAGS} -v  -o user-api cmd/main.go

gocyclo

gocyclo 用來檢查函數的復雜度。
github.com/fzipp/gocyclo
gocyclo -over 12 $(ls -d */ | grep -v vendor)

interfacer

interfacer 是一個有趣的工具，依照作者所說：
這個工具提供接口類型的建議，換句話說，它會對可以本沒有必要定義成具體的類型的代碼提出警告
github.com/mvdan/interfacer/cmd/interfacer

deadcode

deadcode會告訴你哪些代碼片段根本沒用。
github.com/tsenart/deadcode

gotype

gotype會對go文件和包進行語義(semantic)和句法(syntactic)的分析,這是google提供的一個工具。
golang.org/x/tools/cmd/gotype

misspell

misspell用來拼寫檢查，對國內英語不太熟練的同學很有幫助。
github.com/client9/misspell

staticcheck

staticcheck是一個超牛的工具，提供了巨多的靜態檢查，就像 C#生態圈的 ReSharper 一樣。
honnef.co/go/staticcheck/cmd/staticcheck

gosimple

gosimple 提供信息，幫助你了解哪些代碼可以簡化。
honnef.co/go/simple/cmd/gosimple
譯者按： 事實上這個工具和上面的staticcheck工具已經合並為同一個項目了：go-tools，這個項目提供了非常好的工具， 還包括 structlayout-optimize、unused、rdeps、keyify等，值的你去探索。

goconst

goconst 會查找重復的字符串，這些字符串可以抽取成常量。
github.com/jgautheron/goconst/cmd/goconst

Staticcheck-先進的Go linter

https://github.com/dominikh/go-tools
honnef.co/go/tools/... 是用於處理Go代碼的工具和庫的集合，其中包括短絨和靜態分析，其中最突出的是staticcheck。
https://staticcheck.io/docs/
Staticcheck是用於Go編程語言的靜態分析工具集。 它帶有大量檢查，與各種Go構建系統集成，並提供足夠的可定制性以適合您的工作流程。
