What Is Ruby? What Is Rails? Matters of Ruby Style How to Read This Book Digging Deeper Making Sense of the Text Downloading Ruby Getting the Source Code of the Sample Programs Running Ruby Programs The Ruby Library Documentation
1. Strings, Numbers, Classes, and Objects
Getting and Putting Input Strings and Embedded Evaluation Numbers Comments Testing a Condition: if..then Local and Global Variables Classes and Objects
Instance Variables Retrieving Data from an Object Messages, Methods, and Polymorphism Constructors: new and initialize Inspecting Objects
2. Class Hierarchies, Attributes, and Class Variables
Superclasses and Subclasses Passing Arguments to the Superclass Accessor Methods Attribute Readers and Writers Calling Methods of a Superclass Class Variables
3. Strings and Ranges
User-Defined String Delimiters Backquotes String Handling
Concatenation What About Commas? String Assignment Indexing into a String Removing Newline Characters: chop and chomp Format Strings
Ranges
Ranges of Strings Iterating with a Range
4. Arrays and Hashes
Arrays
Creating Arrays Multidimensional Arrays Iterating over Arrays Indexing into Arrays Copying Arrays Testing Arrays for Equality Sorting Arrays Comparing Values Array Methods
Hashes
Creating Hashes Indexing into a Hash Copying a Hash Hash Order Sorting a Hash Hash Methods
5. Loops and Iterators
for Loops Blocks and Block Parameters Iterating upto and downto Multiple Iterator Arguments while Loops
while Modifiers Ensuring a while Loop Executes at Least Once
until Loops loop
6. Conditional Statements
if..then..else and, or, and not Negation if..elsif unless if and unless Modifiers Case Statements
The === Method Alternative Case Syntax
7. Methods
Class Methods What Are Class Methods For? Class Variables Ruby Constructors: new or initialize? Singleton Methods Singleton Classes Overriding Methods Public, Protected, and Private Methods
8. Passing Arguments and Returning Values
Summarizing Instance, Class, and Singleton Methods Returning Values Returning Multiple Values Default and Multiple Arguments Assignment and Parameter Passing Integers Are Special The One-Way-In, One-Way-Out Principle Modifying Receivers and Yielding New Objects Potential Side Effects of Reliance on Argument Values Parallel Assignment
9. Exception Handling
rescue: Execute Code When Error Occurs ensure: Execute Code Whether or Not an Error Occurs else: Execute Code When No Error Occurs Error Numbers retry: Attempt to Execute Code Again After an Error raise: Reactivate a Handled Error
10. Blocks, Procs, and Lambdas
What Is a Block? Line Breaks Are Significant Nameless Functions Look Familiar? Blocks and Arrays Procs and Lambdas Block or Hash? Creating Objects from Blocks What Is a Closure? yield Blocks Within Blocks Passing Named Proc Arguments Precedence Rules Blocks as Iterators
11. Symbols
