go-errors

A simple Go error utility to record the error stack trace, which supports customized formatting and is easy to migrate.

How to

Replace import paths of import "errors" by:

import "github.com/IguteChung/go-errors"

Replace all the occurences of fmt.Errorf by:

errors.Errorf("something wrong: %v", err)

You are done, let's get the stacktrace

fmt.Println(errors.StackTrace(err))

Output:

/tmp/sandbox647637562/prog.go:24
/tmp/sandbox647637562/prog.go:19
/tmp/sandbox647637562/prog.go:14

More customization

Apply custom format for stack trace:

func init() {
	errors.ApplyFormatter("foo\n\tfile.go:152\n")
}

Output:

main.bar
	/tmp/sandbox639852497/prog.go:24
main.foo
	/tmp/sandbox639852497/prog.go:19
main.main
	/tmp/sandbox639852497/prog.go:14
