Example: You have a branch refactor that is quite different from master. You can't merge all of the commits, or even every hunk in any single commit or master will break, but you have made a lot of improvements there that you would like to bring over to master.

Note: This will not preserve the original change authors. Only use if necessary, or if you don't mind losing that information, or if you are only merging your own work.

On master:

> git co -b temp

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

# Angular 2.0.0-rc.1 renamed a bunch of modules. This script can help you do a
# little bit of the dirty work for renaming those modules.
#
# As a bonus, this script will try to fix your template-local variables
# e.g. *ngFor="#thread of threads" becomes -> *ngFor="let thread of threads"

The Problem

In Javascript this is bound in unexpected ways. Functions, in particular, create a new 'this' and so when you want to keep a reference to an "outer" object you sometimes see the pattern:

var self = this;

as in:

var self = this;

/// <reference path="../../typings/app.d.ts" />
//
//  Creates a pipe suitable for a RxJS observable:
//
//        @View({
//          template: '{{ someObservable | rx}}'
//          pipes: [RxPipe]
//        })
// 
// Originally written by @gdi2290 but updated for 2.0.0.alpha-35 and use AsyncPipe
