rlog

====

_rust log or robert's log if you like ;)_  

Mostly for my own projects, with inspiration taken from https://crates.io/crates/env_logger.

This package implements [`github.com/apex/log.Handler`](https://github.com/apex/log/blob/master/logger.go#L54). 

It also offers a subset of [`apex/log.Interface`](https://github.com/apex/log/blob/master/interface.go#L4) that can be used directly.

The environment variable `GO_LOG` can be used to set the log level. Like `env_logger` we support tuning it on a package

basis, e.g. `GO_LOG=warn,sub=debug` would only log warn/error/fatal messages with exception of in the `sub` package,

where all logs get through.

## Usage

Really simple, just import the package and use it:

```

package main

import "github.com/robertgzr/rlog"

func main() {

    rlog.Info("hello world!")

}

```

### To integrate with apex/log:

```

package main

import (

    "github.com/apex/log"

    "github.com/robertgzr/rlog"

)

func main() {

    log.SetHandler(rlog.Default)

    log.SetLevel(log.DebugLevel) // this overwrites the GO_LOG env

    log.Debugf("%s is a string", "a string")

}

```

## Examples

Run `GO_LOG=warn,subpkg=debug go run _example/main.go`
