Nothing too complicated, just go to Ruby's page, then click on "Downloads", and download the One-Click Installer for Windows.

In Ruby, everything is object. Absolutely everything.

An integer, a string, and even classes, as surprising as it may seem. Using irb, we will be able to test Ruby's basic syntax and directly view the result, without having to create a file containing our code a. The command prompt has changed.

You can now directly type your orders.

Try typing the following lines:. Many things in this simple example. We have just created two variables, a and b, and assigned them values.

Then we decided to display their sum using the puts method. To accomplish this goal, the Ruby on Rails Tutorial takes an integrated approach: you will learn Rails by example by building a substantial sample application from scratch.

If you are used to skipping around in technical books, taking this linear approach might require some adjustment, but I suggest giving it a try. You can think of the Ruby on Rails Tutorial as a video game where you are the main character, and where you level up as a Rails developer in each chapter. The exercises are the minibosses.

The Learn Enough Society

Fol- lowing the scaffolding approach risks turning you into a virtuoso script generator with little and brittle actual knowledge of Rails. At each stage of developing the sample application, we will write small, bite-sized pieces of code—simple enough to understand, yet novel enough to be challenging.

There are also many web development shops that specialize in Rails, such as ENTP, thoughtbot, Pivotal Labs, and Hashrocket, plus innumerable independent consultants, trainers, and contrac- tors.

What makes Rails so great? Rails also adapts rapidly to new developments in web technology and frame- work design. The comments below contain some suggestions for approaching the Rails Tu- torial depending on your background. The answer depends on your personal learning style and how much 1.

Another common question is whether to use tests from the start. Inexperienced programmers: The Rails Tutorial is not aimed principally at beginning programmers, and web applications, even relatively simple ones, are by their nature fairly complex.

Experienced programmers new to web development: Your previous experi- ence means you probably already understand ideas like classes, methods, data structures, etc. Ruby even lets you put semicolons at the ends of lines if you miss them too much.

Experienced web developers new to Rails: You have a great head start, es- pecially if you have used a dynamic language such as PHP or even better Python. The basics of what we cover will likely be familiar, but test-driven development may be new to you, as may be the structured REST style favored by Rails.

Ruby Books

Ruby has its own idiosyncrasies, so those will likely be new, too. Among other things, the techniques here may be more up-to-date than the ones you picked up when you originally learned Rails.You also need to understand that a programming language is a formal language. There are also many web development shops that specialize in Rails, such as ENTP, thoughtbot, Pivotal Labs, and Hashrocket, plus innumerable independent consultants, trainers, and contrac- tors.

This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on Rails Tutorial is what I used to switch back to Rails again.

Ruby even lets you put semicolons at the ends of lines if you miss them too much. In a hurry to get started?

There are also many web development shops that specialize in Rails, such as ENTP, thoughtbot, Pivotal Labs, and Hashrocket, plus innumerable independent consultants, trainers, and contrac- tors. Sec- tion 6.

First, I tried to separate concepts as much as possible, so that the student would only have to learn one concept at a time.

Experienced web developers new to Rails: You have a great head start, es- pecially if you have used a dynamic language such as PHP or even better Python.
