Logger

Build Status

Logger is a simple but powerful logging utility to output messages in your Ruby program.

Logger has the following features:

  • Print messages to different levels such as info and error
  • Auto-rolling of log files
  • Setting the format of log messages
  • Specifying a program name in conjunction with the message

Installation

Add this line to your application's Gemfile:

gem 'logger'

And then execute:

$ bundle

Or install it yourself as:

$ gem install logger

Usage

Simple Example

require 'logger'

# Create a Logger that prints to STDOUT
log = Logger.new(STDOUT)
log.debug("Created Logger")

log.info("Program finished")

# Create a Logger that prints to STDERR
error_log = Logger.new(STDERR)
error_log = Logger.error("fatal error")

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
