(*single class psr compatible php logger*)

[![Build Status](https://camo.githubusercontent.com/77b920461e3798bca959d21e8db2a44f22d2dfd91cda1a9de061d8764a7d9f72/68747470733a2f2f7472617669732d63692e6f72672f616e647265772d6b616d656e6368756b2f6465662d6c6f676765722e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/andrew-kamenchuk/def-logger)

basic usage:

```
use def\Logger\Logger;

$logger = new Logger('php-app'); // or Logger::getLogger('php-app');
```

Now you can set a callable writer to process log messages:

```
$logger->setWriter('print_r');

// or
// will print_r every 10 records formatted with default formatter
$logger->setWriter('print_r', Logger::ALL, 10);
```

There are some writers already defined, for example:

```
$logger->setStreamWriter(STDERR, Logger::DEBUG | Logger::INFO); // there are also error_log, syslog and mail writers
```

You can change default formatting:

```
$logger->setDefaultFormatter(function ($levelname, $message, array $context) {
    //
});
```

or pass custom formatter with writer:

```
$logger->setWriter('print_r', Logger::ALL, 10, function ($levelname, $message, array $context) {
    //
});
```

It is possible to disable some levels for handling:

```
$logger->disable(Logger::DEBUG | Logger::INFO);
```

`addContextProcessor` method allows add some extra data to context:

```
$logger->addContextProcessor('some_key', function (array $context) {
    return 'some_value';
});
```
