[![Go Reference](https://pkg.go.dev/badge/github.com/suzuki-shunsuke/slog-error.svg)](https://pkg.go.dev/github.com/suzuki-shunsuke/slog-error)

Go library to embed args into error for [slog](https://pkg.go.dev/log/slog)

## Usage

This library provides only two APIs.

```go

// WithError gets args from err and returns a new logger with err and args.

func WithError(logger *slog.Logger, err error) *slog.Logger

// With returns an error with args.

func With(err error, args ...any) error

```

```go

package main

import (

	"errors"

	"fmt"

	"log/slog"

	"os"

	"github.com/suzuki-shunsuke/slog-error/slogerr"

)

func main() {

	logger := slog.New(slog.NewTextHandler(os.Stdout, &slog.HandlerOptions{}))

	if err := core(); err != nil {

		// time=2023-12-29T22:30:06.992+09:00 level=ERROR msg="command failed" name=mike error="user is not found"

		slogerr.WithError(logger, err).Error("command failed")

	}

}

func core() error {

	if err := getUser(); err != nil {

		return fmt.Errorf("get a user: %w", err)

	}

	return nil

}

func getUser() error {

	return slogerr.With(

		errors.New("user is not found"),

		"name", "mike")

}

```
