The Tcl/Tk combination is increasingly popular because it lets you produce sophisticated graphical interfaces with a few easy commands, develop and change scripts quickly, and conveniently tie together existing utilities or programming libraries.
The Tcl/Tk Pocket Reference,a handy reference guide to the basic Tcl language elements, Tcl and Tk commands, and Tk widgets, is a companion volume to Tcl/Tk in a Nutshell.
Paul Raines is a physicist and scientific programmer at the Stanford Linear Accelerator Center at Stanford University where he is part of a large collaboration studying CP violation (why charge and parity are not conserved in some particle decays). He is a huge advocate of scripting languages and has been using Tcl on various projects since 1992. He is also the coauthor of O'Reilly & Associates' Tcl/Tk in a Nutshell. When he can get away from the lab, Paul enjoys hiking, bridge, and soccer.
During the three solid years of Tcl/Tk work I had, this Tcl/Tk Pocket Reference always travelled with me in my back left pocket.
This book was very helpful as the commands and options were easy to reference and were presented/defined clearly. I preferred using the Tcl/Tk Pocket Reference over querying help from the command line/interpreter.
Being one of the first, if not the first O'Reilly Pocket Reference, this book is a classic and a must-have.
I couldn't imagine a Tcl/Tk programmer without it.
This reference is concise, up to the point, and the Tcl/Tk commands excellently explained. Every command is easy to find and the sytax covered fully. Nothing more to say about that. This is the only reference you need apart from the manual pages that come with Tcl/Tk. I carry the book around nearly everywhere I work with Tcl.
But, since Tcl is now arriving version 8.5 and the book is covering 8.0.3, it is quite out of date. We need a refresh soon!! Please!!!!
