Complex errors for golang

Errored: flexible error messages for golang

Package errored implements specialized errors for golang that come with:

• Debug and Trace modes
  • Debug emits the location the error was created, Trace emits the whole stack.
• Error combination
  • Make two errors into one; carries the trace information for both errors with it!

Use it just like fmt:

package main

import "github.com/contiv/errored"

func main() {
	err := errored.Errorf("a message")
	err.SetDebug(true)
	err.Error() // => "a message [ <file> <line> <line number> ]"
	err2 := errored.Errorf("another message")
	combined := err.Combine(err2)
	combined.SetTrace(true)
	combined.Error() // => "a message: another message" + two stack traces
  combined.Contains(err2) // true
}
