A simple way to configure log in your gem.

LogMe is especially useful when you need to log Web Service calls or HTTP requests and responses, using Net::HTTP or RestClient.

gem 'log-me'

$ gem install log-me

In your gem:

require 'log-me'

module CoolGem
  extend LogMe
end

module CoolGem
  class SomeClass
    def do_something
      # Do something and log
      CoolGem.log "I am logging something here."
    end
  end
end

Using your gem:

some = CoolGem::SomeClass.new
some.do_something

By default will be logged in STDOUT using log level :info:

I, [2011-08-24T01:22:52.677395 #3026]  INFO -- : [CoolGem] I am logging something here.

Logging Net::HTTP requests and responses:

module CoolGem
  class WebService
    def do_something
      url = "http://prodis.blog.br"

      # Some logic to create a Net::HTTP request class.
      request = create_request
      CoolGem.log_request request, url

      # Some logic to obtain a Net::HTTP response.
      response = do_request(request, url)
      CoolGem.log_response response

      response
    end
  end
end

ws = CoolGem::WebService.new
ws.do_something

Logging RestClient requests and responses:

module CoolGem
  class WebService
    def do_something
      args = {
        method: :post,
        url: "http://prodis.blog.br",
        payload: 'param1=value1&param2=value2'
      }

      RestClient::Request.execute(args) do |response, request, result|
        CoolGem.log_request request, args[:url]
        CoolGem.log_response result
        response
      end
    end
  end
end

ws = CoolGem::WebService.new
ws.do_something

In the log:

[CoolGem] Request:
POST http://prodis.blog.br/some_resource
param1=value1&param2=value2

[CoolGem] Response:
HTTP/1.1 201 Created

Your gem consumer can configure the logger:

CoolGem.configure do |config|
  config.log_enabled = false     # Disable log
  config.log_level = :debug      # Change the log level
  config.log_label = "CoolLabel" # Change label to log messages
  config.logger = Rails.logger   # Use the Rails logger

• Fernando Hamasaki de Amorim (prodis)

• Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet.

• Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it.

• Fork the project.

• Start a feature/bugfix branch.

• Commit and push until you are happy with your contribution.

• Don’t forget to rebase with branch master in main project before submit the pull request.

• Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.

• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
