Make your errors beautiful, because writing them is boring enough.

• Automatically wrap your errors with the package and calling function name.
• Keep it simple, and just plainly wrap your errors with Handle(err, "myFunction", "some", "args").
• Full control over what is/isn't included in your errors. Include as much detail as you need to help with debugging.
• Performant. StackErr is only invoked when handling errors.
• Fully interoperable with other error handlers.

go get github.com/ovotech/stackerr

package main

import (
	"log"
	"strconv"

	"github.com/ovotech/stackerr"
)

func myFunction(input string) error {
	if _, err := strconv.Atoi(input); err != nil {
		return stackerr.Handle(err, "atoi", input, "some", "added", "details")
	}

	return nil
}

func main() {
	if err := myFunction("foo"); err != nil {
		log.Panic(err)
	}

	// panic: main.myFunction.atoi("foo", "some", "added", "details"): strconv.Atoi: parsing "foo": invalid syntax
}

If you use golangci-lint and the wrapcheck linter, you should add this package to your config to prevent errors:
