Prerequisites

We'll use NixOps to deploy, so we need to install it

nix-env -i nixops

And to deploy on DigitalOcean we need to have an account and create an API access token for it.

A step-by-step guide how to use Tor without Authentication

Tested on Ubuntu 16.04 Docker container. The Dockerfile is a single line FROM ubuntu:16.04.

NOTE: stopping services didn't work for me for some reason. That's why there is pidof <service name> | xargs kill after each failed service <service name> stop to kill it.

Checkout a Pull Request with git

Add the following to your user's git config file (~/.gitconfig for linux):

[alias]
        pr = "!f() { git fetch -fu ${2:-origin} refs/pull/$1/head:pr/$1 && git checkout pr/$1; }; f"

Then use the command in the project directory, like this:

git pr NUMBER_OF_PULL_REQUEST REMOTE

  // save a reference to the original constructor
  var original = target;
 
  // a utility function to generate instances of a class
  function construct(constructor, args) {
    var c : any = function () {
      return constructor.apply(this, args);
