Lo, the reviewing hero has returned: Jason Bennett has returned with a review of Mark Harrison and Michael McLennan's effort Effective Tcl/Tk Programming. Designed as a book for those going deeper with their Tcl/Tk knowledge, this book works for those of you beyond the introductory page. Click below for more information. Effective Tcl/Tk Programming author Mark Harrison and Michael McLennan pages publisher Addison Wesley Publishing Company, Inc. rating 8/10 reviewer Jason Bennett ISBN 0-201-63474-0 summary A book for advanced Tcl/Tk programmers with thorough examples and good tips. As with most advanced books, it's probably better as a reference book than for pure reading, but its coverage is thorough enough to teach most Tclites a few tricks. Background

Greetings, all, I'm back once again. After my travels into the world of Tk a few weeks ago, I've branched out to include its sibling, Tcl, in all its glory. Tcl, I have to say, reminds me a lot of Lisp, at least in its typelessness and fondness for lists. I do miss all the (()), though :-).

What's the book about?

Generally speaking, it is designed as a sequel to any and all introductory Tcl books with a view toward more advanced and narrow concepts. The authors go through various parts of Tcl that the novice programmer might not use frequently, but the advanced programmer will find quite useful. The geometry managers are all covered in detail, so the advanced programmer can select the best one. The canvas widget, that all-purpose blank slate, is given quite a bit of room. The book even covers communicating with other programs on the same machine and through sockets. Most all aspects of Tcl and Tk are addressed to some extent, leaving few stones unturned. Of course, programmers on different levels and with different experiences will find different nuggets in here. Personally, I was well acquainted with the text widget, making chapter five somehwat redundant, but needed some help with communicating with other processes. YMMV. Generally, the book is composed of several large examples, with new features added in each chapter. There certainly is a great deal of code, relative to the amount of explanation, so a good grasp of Tcl is required. In addition, the final chapters deal with delivering a complete, cross-platform Tcl application to the marketplace, in terms of packaging and cross-platform compatability. There's a nice install program example, and plenty of cross-platform minefields mentioned.

What's Good?

This book is excellent for any Tcl programmer who's looking to add one of the skills covered in this book to his bag o'tricks. If you want to know more about text widgets, or using Tcl as a front-end to other programs, there's plenty of explanation and example to glean from this book. If you want to know more about general Tcl concepts like the event loop or the geometry manager, there's still more for you. There are also plenty of concepts addressed that could be applied to other GUI efforts outside of pure Tcl/Tk. I wouldn't necessarily read the book just for those, but they are a welcome addition. The examples in particular are quite thorough, with extra code available that is not printed in the book. There's even an entire calander manager written that's quite full-featured. Any topic covered comes with not only text but plenty of code. Commercial Tcl developers will especially appreciate the emphasis on professional Tcl libraries and delivery. If you do Tcl for a living, you'll appreciate this book.

What's Bad?

If you don't want to delve deep into Tcl, don't bother with this book. You'll end up having to deal with areas of the language you never wanted to know, and you'll end up frustrated. Similarly, I wouldn't recommend reading this from beginning to end unless you love Tcl. There are plenty of parts where the flow is bogged down by the endless obscure code, and if you aren't interested, you'll end up skipping it anyways. Skim the parts that you don't need now, and come back to them.

What's In It For Us?

Since I know there are plenty of Tcl fans out there, I'm sure there will be plenty of interest in this book. As I said, if you're just starting with Tcl, hold off on this one. If, however, you've honed your Tcl skills, but need some extra help in some areas, this book is for you. Whether you're into sockets with Tcl or just want to use that text widget more effectively, you will find this book useful. I'm sure it will be coming off the shelf for reference much in the future.
