Logem, short for "Let's Log em!", is an opinionated handler wrapper for [slog](https://pkg.go.dev/golang.org/x/exp/slog).

It combines a LevelHandler and a TraceHandler in a single, simple to use handler.

## Disclaimer

This package is not suited for production use right now. It is heavily being worked on.

However feel free to inspire yourself from it or fork it.

## Installation

```shell

go get -u github.com/mgjules/logem

```

## Usage

```go

package main

import (

  "context"

  "os"

  "github.com/mgjules/logem"

  "golang.org/x/exp/slog"

)

func main() {

  // Init OTEL trace provider.

  // initTraceProvider()

  // Create logger using logem.Handler.

  logger := slog.New(

    logem.NewHandler(

      slog.NewTextHandler(os.Stdout),

      logem.WithMinLevel(slog.LevelInfo),

      logem.WithStackTrace(true),

      logem.WithTraceID(true),

      logem.WithSpanID(true),

    ),

  )

  slog.SetDefault(logger)

  // Use logger to log messages, etc.

  // Please ensure that the context being passed has proper trace information.

  ctx := context.TODO()

  logger.WithContext(ctx).Info("hello", "count", 3)

}

```
