logger-better

Simple Logger subclasses to make it easier to use and print more compact log messages. It also contains modules you can monkey patch into Logger if you don't want to use the subclasses, or don't have control over objects instantiating Logger instances.

I wrote this gem because I've done this same basic thing in many projects and got tired of it.

Add this line to your application's Gemfile:

gem 'logger-better'

And then execute:

$ bundle

Or install it yourself as:

$ gem install logger-better

• Default log format is more readable: 2013-08-10T15:19:21Z [app#68530] INFO: hi
• Includes a formatter without timestamps. Useful when your logging solution automatically inserts them.
• Set logger.level with symbols. logger.level = :info (Works nicely with ENV['LOG_LEVEL'])
• Provide a NullLogger object to be used in cases where you need to tell some code to shut up.

logger-better has two modes: subclasses and monkey patches to the Logger class. Monkey patching is OPT IN. This library includes a Logger::Better subclass. It just a subclass with the appropriate modules included. Logger::Better instances will use bundled formatter by default. Logger::Better also provides a factory for creating timestampless loggers (using one of the bundled formatters).

require 'logger-better'

logger = Logger::Better.new $stdout
logger.info('testing') { 'Hello World' } # => 2013-08-10T15:19:21Z [app#68530]  INFO: Hello World

# Notimestamp factory method behaves the same as new, just sets the
# default formatter
logger = Logger::Better.no_timestamp $stdout
logger.info('testing') { 'Hello World' } # => [app#68530]  INFO: Hello World

require 'logger/better'

logger = Logger.new $stdout
logger.info('testing') { 'Hello World' } # => 2013-08-10T15:19:21Z [app#68530]  INFO: Hello World

require 'logger/no_timestamp'

# Notimestamp factory method behaves the same as new, just sets the
# default formatter
logger = Logger.new $stdout
logger.info('testing') { 'Hello World' } # => [app#68530]  INFO: Hello World
