How do I add stack traces to errors in Go?

In Go, you can add stack traces to errors using the third-party packages like `pkg/errors` or `github.com/go-stack/stack`. These packages allow you to wrap errors and include a stack trace, making debugging easier.

Here’s an example of how to use `pkg/errors` to add stack traces to your errors:


        package main
        import (
            "fmt"
            "github.com/pkg/errors"
        )

        func main() {
            // Example of a function that returns an error
            err := doSomething()
            if err != nil {
                fmt.Println(errors.Wrap(err, "an error occurred"))
            }
        }

        func doSomething() error {
            // simulate an error
            return errors.New("something went wrong")
        }
