Javascript `log` Function

Every time I start a new project, I want to pull in a log function that allows the same functionality as the console.log, including the full functionality of the Console API.

There are a lot of ways to do this, but many are lacking. A common problem with wrapper functions is that the line number that shows up next to the log is the line number of the log function itself, not where log was invoked. There are also times where the arguments get logged in a way that isn't quite the same as the native function.

This is an attempt to once and for all document the function that I pull in to new projects. There are two different options:

The full version: Inspired by the plugin in HTML5 Boilerplate. Use this if you are writing an application and want to create a window.log function. Additionally,

This readme is a mixture of everything I read on SO+nokogiri wiki, which ultimately worked out for me.

Here are the steps which worked for me to get rid of segfaults with Nokogiri 1.4.4, on both Lion and Snow Leopard, with Ruby 1.8.7 (patchlevel 334 and +).

First diagnose which version of libxml2 you're using:

bundle exec nokogiri -v

If you have 2.7.3 listed somewhere, you're in bad waters (known to segfault). Install this:

	RSpec.configure do \|config\|
	config.before(:suite) do
	DatabaseCleaner.clean_with(:truncation)
	end

	config.before(:each) do
	DatabaseCleaner.strategy = Capybara.current_driver == :rack_test ? :transaction : :truncation
	DatabaseCleaner.start
	end

	#
	# UPDATE for 10.10.4+: please consider this patch obsolete, as apple provides a tool called "trimforce" to enable trim support for 3rd party SSDs
	# just run "sudo trimforce enable" to activate the trim support from now on!
	#
	# Original version by Grant Parnell is offline (http://digitaldj.net/2011/07/21/trim-enabler-for-lion/)
	# Update July 2014: no longer offline, see https://digitaldj.net/blog/2011/11/17/trim-enabler-for-os-x-lion-mountain-lion-mavericks/

	namespace :db do
	namespace :enable do
	desc "enable hstore extension"
	task :hstore => [:environment, :load_config] do
	ActiveRecord::Base.connection.execute('CREATE EXTENSION IF NOT EXISTS hstore;')
	end
	end

	Rake::Task['db:schema:load'].enhance ['db:enable:hstore']
	end

	# Rake task to launch multiple Resque workers in development/production with simple management included

	require 'resque/tasks' # Require Resque tasks

	namespace :workers do

	# = $ rake workers:start
	#
	# Launch multiple Resque workers with the Rails environment loaded,
	# so they have access to your models, etc.

	# This all assumes you have the process running in
	# a terminal screen and you're on Linux-like system.

	# First off, suspend the process and background it
	ctrl-z # suspend the process
	bg # restart/continue the process in the background

	# Now create files to log to. They can be called anything,
	# Personally I would end the in .log. E.g. could be
	# /var/logs/myprocess-stdout.log,

	//
	// Backbone.Rails.js
	//
	// Makes Backbone.js play nicely with the default Rails setup, i.e.,
	// no need to set
	// ActiveRecord::Base.include_root_in_json = false
	// and build all of your models directly from `params` rather than
	// `params[:model]`.
	//
	// Load this file after backbone.js and before your application JS.
