Gem needs to access project specific folder

I am planning to create a ruby gem project and finally add that library gem in to another project. gem does some extra steps which needs to be completed before project feature file execution. Now i need to access the project feature folder from this gem. I tried this code

feature_folder= File.join("**", "features")
Dir.glob(feature_folder)

but didnt work. Is there anyway i can access the project features folder from my gem? I couldn't find how exactly cucumber access the project folders ( features , step_definitions) from cucumber gem.

Why in ruby, 0.692 * 3 = 2.0759999999999996?

$ ruby -v
ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14]

$ irb
irb(main):001:0> 0.692 * 3
=> 2.0759999999999996

I just ran into these numbers by chance. Is this related to Why Are Floating Point Numbers Inaccurate?.

How is it that you can do `Integer('1')` in Ruby?

How does the standard library allow you to coerce a String into an Integer with Integer('1') #=> 1? Is there a language feature that allows one to create this kind of conversion syntax in a class?

Getting a file name instead of directory name in Ruby

PLEASE NOTE THAT I AM A NOOB

So I recently started learning Ruby and a buddy is motivating me to get into it so he helped me get on my way. We're currently building a program that allows you to download the HTML code from a page. My code isn't working. The code is:

require 'net/http'

print "Source: "
source = gets.chomp

print  "Path: "
filename = gets.chomp

page = Net::HTTP.get(source, path) 
path = File.join(File.dirname(__FILE__), filename)
file = File.open(path, 'r+')
file.write(page)
file.close()

and the error message I get is

webdownload.rb:11:in `initialize': Is a directory - ./ (Errno::EISDIR)
from webdownload.rb:11:in `open'
from webdownload.rb:11:in `<main>'

My buddy said it's because I'm declaring a directory name instead of a file name (which I can deduce from the error message). I however don't know how to change it into a file name.

Fixture finder methods

I have two models: User, Group

I have fixtures for both of them.

I have UserTest class which is unitTest and I can use fixture finder users(:someuserfixture). However, if I try to use groups(:somegroupfixture) it says that groups isn't recognized.

How can I access fixtures of another model?

ruby - split an array into sub arrays when a value changes and ignore/delete that value

I want to split the following array into sub arrays so that the sub-arrays start and finish when the 1's start and finish...

a=[1,1,0,0,1,0,1,1,1]

so I end up with this as a new array...

=> [[1,1],[1],[1,1,1]]

anyone got any ideas...?

thanks in advance Matt

Chef, Vagrant and private git cloning

i have acces to git repo on host, and i have a Vagrantfile:

# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "ubuntu14.04"
  config.vm.box_url = "http://ift.tt/1cwfxmd    vagrant-disk1.box"
  config.vm.provider "virtualbox" do |vb|
    vb.memory = 1024
    vb.cpus = 2
  end
  config.ssh.forward_agent = true
  config.vm.provision :chef_solo do |chef|
  # chef.log_level = :debug
    chef.cookbooks_path = "./cookbooks"
    chef.add_recipe "git_sync"
  end
end

if i run vagrant and ssh into it, i could also git clone my private repo, (recipe "install_pkgs" is to install git on vm) but the pecipe "git_sync" gets an error like:

I'm new to chef and vagrant and it would be great to have some very comprehensive examples.
