How to use Tim Pope’s Pathogen

I’ll assume you are on Linux or Mac OSX. For Windows, replace ~/.vim/ with $HOME\vimfiles\ and forward slashes with backward slashes.

The idea

Vim plugins can be single scripts or collections of specialized scripts that you are supposed to put in “standard” locations under your ~/.vim/ directory. Syntax scripts go into ~/.vim/syntax/, plugin scripts go into ~/.vim/plugin, documentation goes into ~/.vim/doc/ and so on. That design can lead to a messy config where it quickly becomes hard to manage your plugins.

This is not the place to explain the technicalities behind Pathogen but the basic concept is quite straightforward: each plugin lives in its own directory under ~/.vim/bundle/, where each directory simulates the standard structure of your ~/.vim/ directory.

require 'sinatra'
require 'warden'

class YourApp < Sinatra::Application
  
  get "/" do
    erb 'index'.to_sym
  end	

  get "/protected_pages" do

Warden::Manager.serialize_into_session{|user| user.id }
Warden::Manager.serialize_from_session{|id| User.get(id) }
 
Warden::Manager.before_failure do |env,opts|
  # Sinatra is very sensitive to the request method
  # since authentication could fail on any type of method, we need
  # to set it for the failure app so it is routed to the correct block
  env['REQUEST_METHOD'] = "POST"
end
