Zog is an advanced, multi-logging library for Ruby with a simple interface.

You can log to Zog through a globally-available Zog module, or manually instantiate multiple instances of Zog for whatever logging usage you see fit. While Zog instances are designed to be a drop-in replacement for Ruby's stdlib's Logger class, they extend Logger's featureset with support for:

• Unlimited outputs of multiple types (file logger, stream/stdout/stderr logger)
• Unlimited toggleable category channels
• Advanced log message formatting support (color, bold, and more)
• Caller identification within the log message

Zog makes debugging and monitoring your code a breeze!

Note that version 0.5 is currently in development, do not use this in production code!

Add this line to your application's Gemfile:

gem 'zog'

And then execute:

$ bundle

Or install it yourself as:

$ gem install zog

In it's default configuration, Zog can be accessed from its global singleton, like so:

Zog.debug("Hello world!")

This will produce the following output on-screen (in STDERR):

20190101-120000 debug in irb_binding(): Hello world!

And the following output in ./log/zog.log:

D, [2019-01-01T12:00:00.000000 #0000] DEBUG -- irb_binding: Hello world!

To try this out, install Zog and load up an IRB console:

irb(main):> require 'zog'
=> true

irb(main):> Zog.debug("Hello")
20190101-120000 debug in irb_binding(): Hello
=> nil

irb(main):> Zog.error("Oh no! Something went wrong!")
20190101-120001 error in irb_binding(): Oh no! Something went wrong!
=> nil

You can instantiate new Zog instances like so:

irb(main):> z = Zog.new
=> #<Zog::Heart [...]>
irb(main):> z.info("Hello from a separate instance!")
20190101-120002 info in irb_binding(): Hello from a separate instance!
=> nil

Zog includes all the Ruby stdlib channels (debug, info, warn, error, fatal, and unknown) plus an other channel and a _zog_internal channel (disabled by default). Zog outputs can have separate channel configurations within a single Zog instance.

TODO

TODO

• Major refactor to modularize and expand functionality
• Added test suite and CI integration
• File logger now uses Ruby's stdlib logger
• Zog is now usable as a singleton or as an instantiated class
• Added configurable channels, outputs, supports for any number in any combination
• Documentation rework for 0.5 (TODO)
