Epilog Gem

Gem Version Build Status Code Climate Test Coverage Inline docs

A JSON logger with Rails support.


Read below to get started, or see the API Documentation for more details.


Add this line to your application's Gemfile:

gem 'epilog'

Basic Usage

This logger is compatible with the native Ruby Logger interface. To use it, just create an instance of Epilog::Logger.

logger = Epilog::Logger.new($stdout)

Rails Support

To use Epilog with Rails, simply override the Rails default logger with an Epilog logger. Do this in your application.rb or <environment>.rb.

config.logger = Epilog::Logger.new($stdout)
config.logger.progname = 'epilog'
config.log_level = :debug


You can run bin/console for an interactive prompt that will allow you to experiment.
