JJM - 2017-07-25 - Got the book in the mail, looks really great. Nice job.arjen - 2017-07-06 19:35:22Congratulations! It is a welcome addition to the Tcl library and a voluminous one at that :)
bll 2017-7-6 Looks very comprehensive. Looking forward to reading it.ALX 2017-07-09 17:45 Year! First! :-) "Well, thanks for your prompt purchase! You are the very first buyer of my book! /Ashok"RLH: Will there be a book/ebook bundle? APN No bundle because of the different distribution channels. But you might be able to make use of the discounted price as noted above. RLH Got them both. Reading through the book now. :)MHo This book is simply overwhelming!
JOB - 2017-11-14 22:15:55Congratulations as well! I quickly went through the TOC which looks really promising. Good to see that all those extensions and functionality recently added to the core like coroutines, TclOO, threads, database connectivity, etc. are all covered by the book. APN Thanks, and that was indeed one of the primary motivations behind writing the book.
SYStems did anyone buy the ebook via gumroad, I googled gumroad and the reviews are really bad.APN When you say reviews, I presume you mean Gumroad and not the book :-) I'm surprised you saw so many negative reviews of gumroad because I chose it based on the positive reviews I'd seen. (Also because they take care of EU VAT without my having to individually file.) I think most negative reviews of gumroad are from the seller's perspective (which would be me), not the buyer's. Personally, I have had no issues with selling through them. About a hundred e-book copies have downloaded so far and have not heard of any complaints from buyers.SYStems yes 100% I meant gumroad, not the book :)DPG This book is great! I got the physical version because I'm just physical like that ;) This book has a good Index, which is important to physical book people. APN Thanks, appreciated. However, such comments on the book's Amazon page would be appreciated even more, hint, hint :-) DPG Done! APN Great! Thank you.SYStems Can you please make available an epub version of the ebook. APN Unfortunately not. I did try producing both epub and mobi formats originally but did not find the results acceptable the way tables and figures were displayed. It just leaves a bad impression about the book.
[aplsimple] - 2018-09-20 04:35:56Dear Ashok,I've found some tiny issues in your book. Below they are listed, an original text is quoted, a comment begins with "-".APN Thanks for the list Alex. I have integrated most of your corrections into the Errata above. The remaining are below with my comments.4. There are no outputs of some commands:Page 373: - should be:
% oo::class create CheckingAccount {
...
==> ::SavingsAccountPage 388: - should be: % oo::class create ClassWithOneArg {
...
==> ::ClassWithOneArg
% oo::class create ClassWithNoArgs {
...
==> ::ClassWithNoArgs
(there are other cases of this)APN This is by design. Commands that are typed at the interactive prompt, and scripts as they might be stored in a file. The former is shown with a % prompt and the output of every command is printed for pedagogic purposes. For the latter, no % prompt is shown and only the output of the last command is shown. Intermediate output is not shown as it only adds to the clutter and is of limited interest. I've mentioned this difference in Section 1.3.1 (Conventions) but of course it's probably not fair of me to expect readers to have read that :-)5. Page 379 (bottom):There is no definition of BillPay class and it is not good because the example would not work in CLI. You might modify it as:
% oo::class create BillPay {} ;# Empty class for demo only
==> ::BillPay
% oo::define CheckingAccount {mixin BillPay EFT}
% info class mixin CheckingAccount
==> ::BillPay ::EFTI mention in the text, "if you had a BillPay class defined", but your way is probably better.6. The problem is that you omit the % tclsh's prompt in many examples throughout the book.It's no problem when there is no output of command or the output is shown in the same line.However, if there is the "==>" output then the corresponding input should be marked (and really very often marked!) with "%".Otherwise a reader may be perplexed with what command ouputs this. It's also a question of consistency.See e.g. sections 14.4.3, 14.6, 14.7, 14.9.1, 14.10, 14.11.3.3.APN See my explanation above for interactive vs. script distinction.Regards, Alex PlotnikovAPN Thanks again![aplsimple] - 2018-09-20 12:48:56Let me repost myself from https://groups.google.com/forum/#!forum/comp.lang.tcl
I'd got here in Voronezh obl., Russia, your book (printed in USA, Middletown, DE, 25 July 2018) in a month after request. Continuously fascinated by the book, esp. while resolving a question from time to time.It takes some comments. The book was got from Amazon indirectly, i.e. at first it had been sent to Europe and only after that to Russia. There was no direct Amazon delivery to Russia maybe because of those sanctions, you know:) The delivery had taken ONE MONTH, money about 2500 roubles (~ $40).The book is amazing. Bible of Tcl indeed and Ashok P. Nadkarni being Tcl apostle. Do not pay much attention to its typos and tiny drawbacks. They are nothing compared with its goods. Moreover, methinks, Ashok would be grateful all of you guys for pointing at the drawbacks whatever they are:)Hopefully this info would help someone.[aplsimple] - 2018-09-23 14:48:07Here
http://aplsimple.ucoz.ru/misc/tcl_book_samples.raris the utility for executing the code samples of "The Tcl Programming Language" book. You can view also a text ch14_tcloo.txt containing the output of utility.All you need to use the utility is
1) insert the code samples into its "bundle" variable, with your comments and debugging stops 2) run the utility from console or your editor (e.g. from Geany IDE with Run command: tclsh "./%f").The utility's special feature is that you need not delete "%" prompts of the book's samples after copy-pasting them. You can also add comments, your own code, debugs and save all into separate chNN*.tcl files which makes the utility rather useful while reading the book's chapters. See details in ch14_tcloo.tcl.The ch14_tcloo.tcl file contains the samples of draft chapter 14 "Object Oriented Programming" available here:
http://www.magicsplat.com/articles/oo.htmlThe samples are numerated according to the draft which is not the same as the book. You can clone the utility for other chapters of the book.It would be nice to include other samples into tcl_book_samples.rar, however there is much sense in purchasing the book and personal playing with its gigantic store of samples.This utility allows to have a convenient summary of read chapter after those code plays. The reading of your own summaries is often the best mode to refresh your knowledge.
[aplsimple] - 2018-09-24 16:36:08Updated (described above)
http://aplsimple.ucoz.ru/misc/tcl_book_samples.rarwould allow to paste a Tcl sample that hasn't the proper indentation. The corresponding updates were borrowed from
http://wiki.tcl.tk/15731The correction of code indentation is important when you copy-paste from a pdf file rather than a html page. The pdf viewers (at least those I've tested) remove the indentation at copying a code snippet. Some of viewers could even distort the resulting code because of %, →, Ø, page titles etc.Adobe pdf reader (in Windows) and Okular document viewer (in Linux) both allow to copy the code snippets of "The Tcl Programming Language" without distortions.
