Product Description: Yes, it is possible to be all things to all people, if you're talking about the Emacs editor. As a user, you can make any kind of customization you want, from choosing the keystrokes that invoke your favorite commands to creating a whole new work environment that looks like nothing ever developed before. GNU Emacs offers a full version of the Lisp programming language, allowing you to create whole new editors or just alter aspects of the many functions it already provides. In this book, Bob Glickstein delves deep into the features that permit far-reaching Emacs customizations. He teaches you the Lisp language and discusses Emacs topics (such as syntax tables and macro templates) in easy-to-digest portions. The realistic examples, each successively refined a number of times, illustrate not only Emacs Lisp, but the development process as well.
