Monolog Cascade Namespaced

What is Monolog Cascade Namespaced?

Monolog Cascade Namespaced is a Monolog Cascade extension that allows you to configure loggers for a specific namespace/class.

---

Installation

Add monolog-cascade-namespaced as a requirement in your composer.json file or run:

$ composer require fluffy/monolog-cascade-namespaced

Note: Monolog Cascade requires PHP 5.3.9 or higher.

Usage

Load configuration (Monolog cascade supports the following config formats: yml, json and php):

<?php

use CascadeNamespaced\CascadeNamespaced;

CascadeNamespaced::fileConfig('path/to/some/config.yaml');

Then just use your logger:

CascadeNamespaced::getLogger(get_called_class())->info('Info message.');

Note: You must pass a full class name into CascadeNamespaced::getLogger() method in order to have possibility to configure this logger in your configuration file in the future if you want it to have specific configuration. You can get a full class name with a help of get_called_class() function.

Configuring

Root logger

Define root logger in your cascade configuration. It will be returned by CascadeNamespaced::getLogger(get_called_class()) if there are no any specific loggers defined for your namespace/class. It's default logger for your application. If there is no root logger defined then default monolog logger will be returned.

handlers:
    console:
        class: Monolog\Handler\StreamHandler
        stream: php://stdout

loggers:
    root:
        handlers: [console]

Namespace/Class specific loggers

Let's say you have next classes:

MyNamespace\Class1
MyNamespace\Class2
MyNamespace\SubNamespace\Class3
MyNamespace\SubNamespace\Class4
AnotherNamespace\Class5

And you want to log messages from MyNamespace\SubNamespace namespace classes into the stdout, but messages from MyNamespace\Class1 and MyNamespace\Class2 classes into two different files. It can be done with next configuration:

handlers:
    file1:
        class: Monolog\Handler\StreamHandler
        stream: log_file_1.log

    file2:
        class: Monolog\Handler\StreamHandler
        stream: log_file_2.log

    console:
        class: Monolog\Handler\StreamHandler
        stream: php://stdout

loggers:
    # Will be used for `AnotherNamespace\Class5` class as a default logger
    # because there are no specific loggers defined for this class.
    root:
        handlers: [console]

    # Will be used for all the classes from `MyNamespace\SubNamespace` namespace.
    MyNamespace\SubNamespace:
        handlers: [console]

    # Will be used for `MyNamespace\Class1` class.
    MyNamespace\Class1:
        handlers: [file1]

    # Will be used for `MyNamespace\Class2` class.
    MyNamespace\Class2:
        handlers: [file2]

For other classes CascadeNamespaced will return root logger as a default logger for the application.
