# MultiLogger

Makes it easier to create multiple log files in Rails.

## Installation

Add this line to your Rails application's Gemfile:

    gem 'multi_logger'

And then execute:

    $ bundle install

Or install it yourself as:

    $ gem install multi_logger

## Usage

To setup a logger, create an initializer script such as `[Rails.root]/config/initializers/logger.rb` with:

    MultiLogger.add_logger('mail')

This will create a log file located at `log/mail.log`.

Then In Rails, you can log by calling the following:

    Rails.logger.mail.debug('42')

The `Rails.` reference can be omitted at the usual places in Rails (e.g. controllers and views).

Note that log_name must not collide with existing method names in Rails logger, so names such as 'debug' or 'info' can not be used. You should try calling `add_logger` in Rails console to test if it is ok or raises an error.

## Advanced

You can assign formatter to loggers directly, or pass the formatter during setup:

    formatter = Proc.new{|severity, time, progname, msg|

      formatted_severity = sprintf("%-5s",severity.to_s)

      formatted_time = time.strftime("%Y-%m-%d %H:%M:%S")

      "[#{formatted_severity} #{formatted_time} #{$$}] #{msg.to_s.strip}\n"

    }

    MultiLogger.add_logger('mail', formatter:formatter)

    MultiLogger.add_logger('user', formatter:formatter)

To set a different path to the log file, use `:path` option.

For example, for setting a different file to each environment use:

    MultiLogger.add_logger('mail', formatter:formatter, path:"mail_#{Rails.env}")
