append stack multiline with zerolog.NewConsoleWriter()

[dryaf]

while developing and using the zerolog.NewConsoleWriter(), i would like to append the stack in a new line (nicely formatted multiline string) instead of inline as an attribute
(maybe this way i can cmd+click it in intellij)

any hints are very welcome?

I was trying to hack this as well.
I would generally like the stack to look just like I called fmt.Sprintf("%+v", err), on error with stack trace created by errors package, as shown in this blogpost by: https://dave.cheney.net/2016/06/12/stack-traces-and-the-errors-package :

not enough arguments, expected at least 3, got 0
main.parseArgs
        /home/dfc/src/github.com/pkg/errors/_examples/wrap/main.go:12
main.main
        /home/dfc/src/github.com/pkg/errors/_examples/wrap/main.go:18
runtime.main
        /home/dfc/go/src/runtime/proc.go:183
runtime.goexit
        /home/dfc/go/src/runtime/asm_amd64.s:2059

Tried to achieve using custom function on :

1. zerolog.ErrorStackMarshaler, but this would add a string to the buffer, and newlines will be formatted as "\n".
2. zerologFormatErrFieldValue / FormatErrFieldName : this would not work as well, as I do not get the error object at this time, only the error message (FormatErrFieldValue) or "error" (FormatErrFieldName).

I would appreciate if there is another solution.

@inoam I use a hack method reslove it : )

func ESPackMarshalStack(err error) interface{} {
	type stackTracer interface {
		StackTrace() errors.StackTrace
	}
	e, ok := err.(stackTracer)
	if !ok {
		return nil
	}
	//It's mean when env=dev just print track
	if utils.Env.Dev() {
		for _, frame := range e.StackTrace() {
			fmt.Printf("%+s:%d\r\n", frame, frame)
		}
	} else {
		return pkgerrors.MarshalStack(err)
	}
	return nil
}

You might want #416.
