Practical Programming in Tcl & Tk, Third Edition
By Brent B. Welch

Table of Contents
Preface


What's New in the Third Edition

The third edition is up-to-date with Tcl/Tk 8.2. The main new Tcl/Tk features are Internationalization, which is covered in Chapter 15, a new regular expression engine, which is described in Chapter 11, and thread-safety. There is a new chapter about compiling C extensions, and there is a more complete C extension example. The chapters on Eval and the Web browser plugin received a thorough update. I made a light sweep through the remainder of the book correcting errors and improving examples. Perhaps the best addition for the reader is an all-new index.

My favorite addition to the book is Chapter 18 that describes TclHttpd, a Web server built in Tcl. TclHttpd provides a number of nice ways to integrate a Web server with a Tcl application, replacing the standard CGI interface with something that is much more flexible and efficient. I have been using this server for the last year to build www.scriptics.com. This freely available server has been used to build several other products, plus it provides an easy way for you to bring up your own Web server.
