Sam-Serpoosh / spec_helper_lite.rb

Created June 1, 2012 10:51

a handy method for requiring all ruby files in a folder which is in rails app folder (like controllers, views, helpers, etc.) really useful in rails specs (for me at least). it can be in a spec_helper_lite file in spec folder.

	def require_folder(folder_name_in_app)
	Dir[File.expand_path(File.dirname(__FILE__) + "/../app/" + folder_name_in_app + "/*.rb"].each { \|file\| require file }
	end

Sam-Serpoosh / current_version_sign_in_out_spec.rb

Created July 17, 2012 21:10

a simple sign_in & sign_out machinery for an app I'm currently working on. I try to follow good OO design & separation of concerns, etc. & extract domain objects as much as possible & have fast-isolated tests. But can't stub simple methods of a module in

	module SessionsHelper
	include SignInOut

	def create_cookie(user_id, user_salt); end

	def remember_token; end

	def delete_cookie; end
	end

Sam-Serpoosh / some_domain_logic_spec.rb

Created July 27, 2012 22:44

This is a little helper method which take the path of a file relative to rails root directory and "require" that file in the test. Comes handy for the isolated tests in a rails project. Interestingly enough, I wrote this via TDD too!

	#you can use this easily like the following in your spec files:

	reuqire_relative "../spec_helper_lite"
	reuqire_relative_to_root "lib/some_domain_logic"

	describe "some domain logic" do
	#specs will be here then
	end

Sam-Serpoosh / web_based_file_explorer.rb

Created October 25, 2012 22:24

Simple webserver which let you explore your files and directories of your system in a browser!

	require 'socket'

	HTTP_HEADER = "HTTP/1.1 200/OK\r\nContent-type:text/html\r\n\r\n"
	CURRENT_DIR = "."
	SPACE_IN_PARAM = "%20"

	def file_explorer
	webserver = TCPServer.new("localhost", 2000)
	loop do
	Thread.start(webserver.accept) do \|session\|

Sam-Serpoosh / closest_to_zero.rb

Created November 14, 2012 05:09

Closest to zero! Just a short program for fun!

	class Closest
	MAX = 2000000000000

	def to_zero(input)
	raise IllegalArgumentException if input.nil? \|\| input.empty?

	closest_to_zero = MAX
	@least_distance = MAX
	input.each do \|num\|
	if closer_to_zero(num)

Sam-Serpoosh / pair-car-cdr.lisp

Created November 20, 2012 04:54

Just a very simple program from SICP book both in Lisp and Ruby to show how much more elegant the code will be when the philosophy of "Code as Data" exist in a language!

	(define make-pair (a, b)
	(lambda (pick)
	(cond (= pick 1) a)
	(cond (= pick 2) b)))

	(define car (x) (x 1))
	(define cdr (x) (x 2))

Sam-Serpoosh / mutator.rb

Created January 10, 2013 00:57

Very simple Mutator for the concept of Mutation-Testing in Ruby! Just for fun :)

	class Mutator
	def initialize(ruby_file)
	@ruby_file = ruby_file
	end

	def run_test
	spec_file_name = @ruby_file.split(/\./)[0]
	system("rspec #{spec_file_name}_spec.rb")
	end

Sam-Serpoosh / swap_pairs.clj

Created July 10, 2013 01:58

Cool way of swapping pairs in a collection in Clojure!!!

	(defn swap-pairs [items]
	(into (empty items)
	(interleave (take-nth 2 (drop 1 items))
	(take-nth 2 items))))

	(swap-pairs [1 2 3 4 5 6]) ;=> [2 1 4 3 6 3]
