First install a Ruby interpreter and a text editor or IDE. In this video I'll explain how to find and install the right interpreter for your operating system and I’ll show a couple of ways in which you can edit and run your Ruby programs.

If you are a Mac user, this video will guide you through the steps needed to write and run your first Ruby programs.

First Steps on a Mac

Here’s a quick tip that could save you a lot of time if you are running Ruby on a Mac. It explains how to use Finder to open a Terminal (for running Ruby programs) in any folder. Easy when you know how!

Mac users: quick tip - open a Terminal in any folder

If you haven’t done much (or any) programming before or if you need a quick revision of the basics of programming, start with this video. This explains the fundamental features of computer programming – how to use variables, constants, methods, arguments and more.

Programming Fundamentals
Step One
4 Lectures 26:51

Ruby can delimit strings with single quotes 'like this' or double quotes "like this". It turns out that double-quoted strings can do a special trick – they can evaluate embedded Ruby code. This lesson explains the fundamentals.

Step One - part one: Strings and embedded evaluation

See it in action: strings

An introduction to objects and methods. How to use the standard methods of Ruby objects and how to create objects with methods of their own.

Step One - part two: Objects and methods

Hands-on sessions are where I encourage you to get at your keyboard and try out bits of Ruby. This hands-on session doesn't introduce new concepts but it does give you some guidance on how to experiment with Ruby as an aid to your study.

Hands-on Session: Ruby basics
Step Two
3 Lectures 13:51

Now we’ll look at how multiple objects can be created from a class and we’ll see how to create and access ‘instance variables’ to store different data for each object.

Step Two - part one: Creating Classes and Objects

See it in action: classes and objects

How to initialize an object’s data at the time of creation using the initialize() method and how to look inside objects using the inspect() and p() methods.

Step Two - part two: Initializing & Inspecting Objects

Test your knowledge of the first two steps.

Step 1 and 2 Quiz

Step Three
3 Lectures 10:47

In this step you will learn how to create class hierarchies in Ruby so that descendent classes inherit the features of their ancestors.

Step Three - part one: Superclasses and Subclasses

See it in action: class hierarchies

This video summarizes the essentials of class inheritance in which different ‘branches’ of subclasses can descend from a common ancestor.

Step Three - part two: Class Hierarchies
Step Four
3 Lectures 08:44

We look at simple ways of creating 'attributes' to access instance variables without having to write 'getter' and 'setter' methods.

Step Four - part one: Attribute Readers & Writers

See it in action: attribute accessors

What is the difference between an @instance_variable and a @@class_variable? This video explains...

Step Four - part two: Class Variables

Test what you've learnt in steps 3 and 4.
Step 3 and 4 Quiz

Step Five
5 Lectures 20:56

An introduction to creating arrays in Ruby, including arrays of mixed types. How to index a single array item and how to append arrays.

Step Five - part one: Arrays

See it in action: arrays

How to index multiple sequential elements in an array, how to specify ranges of elements, and how to iterate over array items.

Step Five - part two: Array indexing and iterating

Time to get back to your keyboard and do some hands-on coding. In this video I suggest that you copy and paste code from the documentation of Ruby's class library. That's a great way to learn about the classes and methods available!

Step Six
3 Lectures 12:45

Hashes (or 'dictionaries') let you create lists of objects indexed using a key – for example, a string key such as "chocolate cake" may index a value such as the cake’s recipe. This step explains the fundamentals of hashes.

Step Six - part one: Hashes

See it in action: hashes

Ruby can return arrays of all the keys and values found in a hash. You can then use array methods to add, delete, reverse and append one array to another.

Step Six - part two: Keys and Values

Test yourself on steps 5 and 6.

Step 5 and 6 Quiz
8 questions
Step Seven
3 Lectures 10:58

How to repeat actions and iterate over collections using for and while loops and some special Ruby methods.

Step Seven - part one: Loops and Iterators

See it in action: loops

Ruby uses Blocks to perform iterative actions. But there is more to Blocks than meets the eye. In a sense, a Ruby Block is like a method without a name. This video explains.

Step Seven - part two: Blocks
Step Eight
3 Lectures 13:13

How to perform tests using 'if', 'elseif' and 'case' statements along with a number of operators to determine whether test conditions are true or false.

Step Eight - part one: Conditional Statements

Ruby has quite a few Boolean operators to test true/false values. They may look simple enough at first sight but be careful. They may not always work quite as you expect!

Step Eight - part two: Boolean operations

See it in action: conditional tests

Step Nine

Modules let you wrap up code for easy reuse – they also provide some of the features of multiple inheritance without the complexities.

Step Nine - part one: Modules and Mixins

See it in action: modules

What is the difference between a local and a global variable? And when is a constant not a constant?
