jekyll_plugin_logger

jekyll_plugin_logger is a Jekyll plugin, packaged as a Ruby gem, that provides colored console logs for Jekyll plugins. It is based on the standard Ruby Logger class.

Log levels are normally set from _config.yml:

• 0: debug
• 1: info
• 2: warn
• 3: error
• 4: fatal
• 5: unknown (displays as ANY)

Usage

The demo/_plugins/ directory demonstrates two ways of working with jekyll_plugin_logger:

• liquid_tag.rb, a Jekyll plugin subclassed from Liquid::Tag.
• support_tag.rb, a Jekyll plugin subclassed from JekyllSupport::JekyllTag.

Installation

To A Jekyll Website

Add the following to your Jekyll website's Gemfile:

group :jekyll_plugins do
  gem 'jekyll_plugin_logger'
end

Install all of the dependent gems of your Jekyll website by typing:

$ bundle

To A Jekyll Plugin Packaged As A Gem

Add the following to your Gem’s .gemspec:

Gem::Specification.new do |spec|
  spec.add_dependency 'jekyll_plugin_logger'
end

Install all of the dependent gems of your Gem by typing:

$ bundle

Configuration

The default log level is info. You can change the log level by editing _config.yml and adding a plugin_loggers section. Within that section, add an entry for the fully qualified name of your plugin class.

For example, the fully qualified class names of the Jekyll plugins provided in demo/_plugins/ are Raw::InlineTag and Support::InlineTag, respectively. Their log levels can be set to debug with the following entries in _config.yml:

plugin_loggers:
  Raw::InlineTag: debug     # Notice the module name is specified as well as the class name
  Support::InlineTag: debug # Notice the module name is specified as well as the class name

Run the Demo

Run the demo by typing:

$ demo/_bin/debug -r

See what happens to the output when you edit the logging levels in the plugin_loggers section of _config.yml. You will have to restart the demo after each modification to _config.yml in order to see the output change.

Additional Information

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