This classic book is the definitive real-world style guide for better Smalltalk programming. This author presents a set of patterns that organize all the informal experience successful Smalltalk programmers have learned the hard way. When programmers understand these patterns, they can write much more effective code. The concept of Smalltalk patterns is introduced, and the book explains why they work. Next, the book introduces proven patterns for working with methods, messages, state, collections, classes and formatting. Finally, the book walks through a development example utilizing patterns. For programmers, project managers, teachers and students -- both new and experienced. This book presents a set of patterns that organize all the informal experience of successful Smalltalk programmers. This book will help you understand these patterns, and empower you to write more effective code.

Small talk is an inevitability of life. Millions of business deals have been signed, millions of friendships have been formed, and millions of relationships have been turned to romance, all because of small talk. In essence, become proficient in small talk or get left behind socially and professionally. If you're not good at small talk, it may seem like an amorphous puzzle that you can't quite figure out. It's especially frustrating when some people make it seem so easy. Small talk can be easy for you too. Once you learn and practice the techniques of the highly successful conversationalists, you'll be able to upgrade your conversations (and your life) to the next level.

Object oriented programming is a way of thinking about problems. Smalltalk is one of the purest incarnations of an object-oriented programming language. Using a pedagogical approach, this book covers all aspects of object oriented programming: first through the study of various preexisting Smalltalk classes, their implementation and use; then through a detailed description of an implementation of an interactive Lindenmayer system and through implementation of a series of calculators. The author addresses such subjects as graphics programming, dependency mechanisms and hierarchical specialization. This book fills the gap for an in-depth self-study reference, permitting the reader to master all aspects of object-oriented programming through a large set of exercises with highly detailed resources. - Downloadable software content for practice applications - Covers all aspects of Smalltalk: theconcepts of primitive objects, classes and instances, static and dynamic inheritance and methods, as well as graphical programming, the dependency mechanisms and the handling of exceptions - Features in-depth studies of two programming projects and annotated solutions to all exercies and appendices

A straightforward, step-by-step introduction to clear and elegant object-oriented programming. Using a language that's perfect for this kind of programming, the book has been tested in numerous courses and workshops over ten years. Programming Smalltalk is particularly suited for readers with no prior programming knowledge. Starting from the first principles of programming, it teaches you how to use and create algorithms (reusable rules for problem-solving) and the basic building blocks of software. It goes on to explain how to develop complete applications and has a whole chapter on web applications as well as case studies. Now translated into English, this edition was completely revised to be consistent with the latest version of Cincom® VisualWorks®, a professional Smalltalk environment. All examples were created using VisualWorks, which is available without cost for educational purposes, and can be downloaded and installed on any up-to-date computer.

Written for Smalltalk programmers, this book is designed to help readers become more effective Smalltalk developers and object technology users.

This book was originally written to support an introductory course in Object Orientation through the medium of Smalltalk (and VisualWorks in particular). However, it can be used as a book to teach the reader Smalltalk, to introduce object orientation as well as present object oriented design and analysis. It takes as its basic premise that most Computer Scientists I Software Engineers learn best by doing rather than from theoretical notes. The chapters therefore attempt to introduce concepts by getting you the reader to do things, rather than by extensive theoretical discussions. This means that these chapters take a hands-on approach to the subject and assume that the student/reader has a suitable Small talk environment available to them. The chapters are listed below and are divided into six parts. The reader is advised to work through Parts 1 and 3 thoroughly in order to gain a detailed understanding of object orientation. Part 2 then provides an introduction to the Smalltalk environment and language. Other chapters may then be dipped into as required. For example, if the reader wishes to hone their Smalltalk skills then the chapters in Part 4 would be useful. However, if at that point they wish to get on and discover the delights of graphical user interfaces in Smalltalk, then Part 5 could be read next. Part 6 presents some more advances subjects such as metaclasses and concurrency which are not required for straight forward Small talk development.
