Welcome to the "book" about Phosphorus Five. Phosphorus Five, also referred to as P5 in this guide, is a lot of different things. It is a simple design pattern, it is an Ajax library, it is a programming language, and it is a framework. Some would also argue that it is a web operating system. What you choose to refer to it as, is really quite irrelevant. The point is that it solves your problems, particularly the ones you’re having, as you try to create rich and interactive web apps. This book aims at being your “one stop guide”, as you start out with P5. A beginner’s introduction. Starting out at the “for dummies level”, and hopefully moving you onwards to the expert level.

During this book, you will learn everything you need to know to create your first Phosphorus Five application - From the first line of code, to deployment in a production environment. My aim is to bring you up to this knowledge in P5, in roughly 2 days. That way, the book becomes very practical, and hands on, progressing rapidly, and you can feel that you have done something constructive fast. We will start out with creating smaller systems, such as simple CRUD apps, and finish up with creating a complete application.
Every construct we go through, will have a practical application for you. The book is a hands on guide, intended to ignite your own creative processes. As we create these practical solutions, we will also discuss the software architecture theory behind our choices. After reading this book, you can consider yourself a senior software architect, easily capable of discussing software architecture, with some of the best architects on the planet.
This book assumes some basic knowledge about HTML, but does not require you to know JavaScript and/or C# from before. However, some basic knowledge of JavaScript and C#, might be beneficial, since we will dive into these technologies in some of the chapters. You can still perfectly take advantage of it, even if you have never created as much as a single line of code in neither JavaScript, C#, nor any other programming languages. This book does not assume you're a programmer from before, although it sometimes helps having done some programming earlier. Some basic CSS knowledge is also beneficial, however not required.
The main programming language in P5 is called "Hyperlambda", and will be the programming language used for almost all of our examples. Even if you have no interest in learning Hyperlambda, the book will still be valuable for you, since it is also a guide to software architecture theory in general. In addition, Hyperlambda is easily extended through C#, so a C# developer will also benefit from reading this book.
We will also touch upon HTML, CSS, and some general programming theory throughout this book. However, most of the book, is dedicated to hands on, practical examples, of actual useful applications, you could probably benefit from having access to, regardless of whether or not you read the book or not.
The book's convention, is created carefully to allow you to understand what is being described. First of all, any property or attribute from Hyperlambda is referenced like [this], where "this" assumes a node's name. This convention is used whenever a node is referenced inline in the text. Emphasized and important points, are written like this.
Inline code is written like this and multiple lines of code is written like the following illustrates.
howdy-world
this-is:A piece of Hyperlambda code!
Advanced topics, which are not necessary to understand in order to proceed, are explicitly marked as such. You will often find a link close to where a topic has been marked as advanced, allowing you to easily skip the advanced parts. Often the advanced topics of P5, is given inline to preserve context. This means, that advanced topics, are equally easily found in the beginning of the book, as they are found at the end of the book.
You can easily skip these advanced topics in your first read, for later to refer to them as the need surfaces. This ensures that the book is not only a beginner's guide, but also of use for the "Shaolin Ninja P5 master developer".
In general, there are 2 different ways of reading this book. There is the "beginner's guide", which doesn't require you do read any of the advanced chapters. This allows you to rapidly get up to speed in your understanding of P5 and software architecture design principles. This type of reading can probably be done in a day or two, following simple copy and paste examples. These examples are intended to demonstrate some idea, while also incorporating some important software architecture design principle - In addition to being hands on useful examples, of problems you would highly likely to need a solution for in your own applications. This allows you to gain terrain very rapidly, as you read the book - While also understanding the underlaying theory for our choices.
Then there's the "master's read through", which is intended for a second reading of the book. This reading will give you a more detailed vision of both P5, and software architecture design principles in general. This way of reading the book expects you to read the "advanced topics".
If this is your first encounter with P5, I would encourage you to skip all the "advanced chapters", to get you up to speed as fast as possible. This type of reading actually expects you to start out your reading at chapter 2. This "track", is created to rapidly make you gain ground, while staying in the flow, with highly applicable and useful examples, intended to leave you with something real and tangible result - In addition to teaching you some very specific and useful concepts.
Sometimes, the book will also include links to YouTube videos, which you can watch, to further increase your understanding of some concept. These are created as additions to the chapters, and often we analyze the code we looked at in the chapters where these videos are included.

This might sound weird, but the book's introduction can actually be found in chapter 8. My reasoning for doing this, is that I want you to have some hands on experience with P5, before we introduce it from a conceptual point of view. I have therefor chosen to wait with the introduction of the book, until you're almost midway through the book.
Periodically, I might create a download of the book, which you can read locally. This will be in the formats offered by GitHub, such as .zip and .tar.gz. These downloads are the "raw source" of the book, which is in Markdown format. It could probably be beneficial for you to use a Markdown viewer, to read the book. I personally use "MacDown" for writing the book.
This way of distributing the book, allows you to create inline comments as you read it, providing answers for exercises, and comments etc. It also allows you to easily create patches and additions to the book. In addition, it makes it easy for you to document your own systems as additions to this book, having a great foundation for the documentation of your own systems. Which means that as you start out creating value on top of P5, you can start documenting your own system, from the point where the book ends. Hence, there might, and should, exist a "gazillion" versions of this book out there, where every version of the book, is equally unique as the system it is describing.
My email address is thomas@gaiasoul.com, and you can find the book's main source at GitHub, which is the place where I prefer you to submit feedback about the book, if you have any.
The current version you are reading, was created around the same time as Phosphorus Five version 5.0 was released. The book might be updated, as changes occurs in Phosphorus Five, and new releases are being created. The book's current version itself is 5.0. However, the book will inevitably change as P5 changes.
