Overview

Go native error library is a great design, but in some scenarios, there are some flaws. In a complex business scenario, it is necessary to quickly locate the code exception location, but the native error only supports viewing the stack data when panic is used. When multiple returns or panic / recover are used, it is difficult to get the actual starting point of the exception. This makes code debugging a lot of difficulties!

Get code

method 1

  go get github.com/lingdor/stackerror

##method 2

go.mod

  require github.com/lingdor/stackerror v0.1.5

  go mod download

#Usage

Get a stackError

err:=stackerror.New("your message")
return err

Throw a stackerror

stackerror.Panic("your message")

Grace method checking error

func aa() error {
    return stackerror.New("err")
}

func main(){
	defer func(){
		if err:=recover();err!=nil {
			fmt.Println(err)
		}
	}()

	err:=aa()
	stackerror.CheckPanic(err)
}

Output:
*stackerror.stackError : err
at main.aa( /Users/user/go/testApp/src/main/aa.go:8 )
at main.main( /Users/user/go/testApp/src/main/aa.go:18 )
at runtime.main( /usr/local/Cellar/go/1.13.4/libexec/src/runtime/proc.go:203 )\
