# log

Log is a simple logging framework for golang.

## Getting Started

```golang
import "git.martin-riedl.de/golang/log"

func main(){
	log.Default.Info("My First Info Message")
}
```

## Multiple Log Instance

Create a new log instance (instead of using the `Default`).

```golang
import "git.martin-riedl.de/golang/log"

var myLog := log.NewLoggerDefault()
myLog.Info("My First Info Message")
```

## Outputs / Formatter / Printer

- `Formatter` defines the output format (e.g. Key/Value or JSON)
- `Printer` defines the message output location (e.g. stdout or file)
- `Output` is a combination of `Formatter` and `Printer`

The following sample creates 2 outputs. The first sends a key/value format to stdout. The second writes messages as JSON format to stdout.

```golang
import "git.martin-riedl.de/golang/log"

var output1 := NewOutput(log.LevelInfo, NewFormatterKeyValue(), NewPrinterStdout()
var output2 := NewOutput(log.LevelError, NewFormatterJSON(), NewPrinterStdout())

var myLog := log.NewLogger(
	[]*Output{output1, output2}
)
myLog.Info("My First Info Message")

```

## Custom Formatter / Printer

If you need a special `Formatter` or `Printer`: simply implement the Interface (same name) and assign it to an `Output`.
