the most easiest way to print stacktrace for error in golang

golang >= 1.13

import

import"github.com/diemus/errors"

Wrap an error when you return it, then you will get an stacktrace when you print it

functest()error {err:=errors.New("test")returnerrors.Wrap(err)}functest2()error {_ ,err:=someLib.do()returnerrors.Wrap(err)}functest1(errerror) {log.Println(err)}

use Cause() to get the original error when you don't want show the full detail of stacktrace

functest2(errerror) {log.Println(errors.Cause(err))}

the other function in standard library "errors" are wrap by this library, so you can replace the standard library with this package

import"github.com/diemus/errors"functest3(errerror) {errors.New("test")errors.Is(err,err)errors.As(err,err)}
