Introduction

There is no doubt that Emacs is the most powerful text editor available! Unfortunately Emacs has quite a reputation for being difficult to learn and hard to use. With this book this will not be true for you, for the following reasons:

Accompanying the book is a CD-ROM with many extensions to Emacs that you can play with in your spare time. Using these extensions, you can customize Emacs in even more ways than those described in the pages of this book.

The CD also contains a file with features that might seem like they are missing in Emacs, when you read the book. Often these features are not missing; to avoid discussing details that are too technical, however, a fix has been made to ensure that the topics are as easily understandable as possible. (This file is discussed in Hour 1.)

The focus in the book is on using Emacs with a graphical interface, either X Window or Microsoft Windows. Thus no time will be wasted on discussing how to make Emacs work when you have a monitor that displays only 25 lines with 80 characters each.

Note - Text within several figures throughout this book is excerpted from The Hitchhiker's Guide to the Galaxy by Douglas Adams.

Which Version and Flavor Does the Book Cover?

The book covers the two major flavors of Emacs, namely GNU Emacs and XEmacs. The focus is on Emacs version 20, but in many places notes are given on differences and incompatibilities with Emacs version 19.

GNU Emacs is a bit faster than XEmacs; on the other hand, XEmacs is more graphically oriented than GNU Emacs. Whichever you choose depends on your personal preferences. Fortunately, you can shift from one to the other or even use both at the same time. They share the same configuration file and, in the first chapter, you will be taught how to make them coexist. Any major differences that exist between them will be pointed out in the book.
