ifyouseewendy / use-sprockets-ouside-rack-application.rake

Created March 28, 2017 21:42

Use Sprockets outside Rack application. I'm working on a script project which is non Rack based. I want to send users an email notification when the script detects a state change. To use Sprockets outside a Rack application is not a common case, so there are not many articles talking about it online. You could count on this.

	desc 'Compile scss files using Sprockets

	+ source file: #{root}/lib/assets/stylesheets/application.scss,
	in which you could require the third party assets
	+ output file: #{root}/build/emai.css
	'
	task :compile do
	require 'third_party_assets'

	root = '~/Workspace/project/'

ifyouseewendy / flatten_a_nesting_array.rb

Created March 14, 2016 07:17

Flatten an array of arbitrarily nested arrays of integers into a flat array of integers. e.g. [[1,2,[3]],4] -> [1,2,3,4].

	# In Ruby, we can just use Array#flatten
	#
	# def flatten(array)
	# array.flatten
	# end

	# In case you want a manmade version
	def flatten(array)
	array.reduce([]) do \|res, element\|
	Array === element ? res += flatten(element) : res << element
