ColorizeLogs

As developers, we often deal with current controller's action, its main view page and the layout associated with it. To trace and debug these logs information, we check the logs through our console.

However, by default, the logs are all in the same color, which makes it difficult to find the ones which we're working on. To simplify our lives and speed up the debugging process, we want to assign different colors to these logs. This will make it much easier for us to spot the right information and save time when we're fixing issues and improving our software.

To ease our development time, we can use this gem. It will colorize the logs for controller's action, view, layout, and etc.

Add this line to your application’s Gemfile:

gem "colorize_logs"

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install colorize_logs

Create an initializer file config/initializers/colorize_logs.rb and add the following code:

# frozen_string_literal: true

colorize_logs_formatter = ColorizeLogs::Formatter.new

colorize_logs_formatter.configure do
  match(/Processing by/) do |msg|
    msg.red
  end

  match(/Rendering layout/) do |msg|
    msg.green
  end

  match(/Rendering.*within layouts/) do |msg|
    msg.green
  end
end

::Rails.logger.formatter = colorize_logs_formatter

That's it. Restart your server and you should see the logs in different colors.

This gem is inspired by Shog gem. All the credits goes to the author of Shog gem. I had to create this one as original gem is not maintained anymore and I wanted minimal stuff from it.

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.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
