Customer comments on this selection.
 Good, not recommended for newbies on their own
I bought this book hoping for a thorough yet pragmatic guide to teach myself from scratch how to write the front half or so of a compiler. I don't recommend this book for that intent. It's just too high level to be the sole source of instruction.
Chapter two dedicates 9-10 pages for scanning. I'm not looking for endless checklists of minutia, but in that 10 pages why spend time on optimizing a DFA? Is that pragmatic?
About 30 pages of chapter two are spent on parsing, and a decent chunk of that is used for figures. To me that speaks of a text intended to accompany an oral presentation. I have no access to such a lecture -- just the book.
The rest of the book covers many many subjects. I look forward to using Programming Language Pragmatics as a reference in the future. But not for teaching oneself to write the front half of a compiler.
 Incredible knowledge in a fairly small book.
Programming Language Pragmatics 2nd Edition (PLP2e) is a fantastic book that covers a great deal of information. It starts with explaining lexing and parsing, and then goes into scope, target machine instructions, control flow, data structures, a number of paradigms, and building a runnable program. It touches on pretty much every aspect of computer programming, and with deep and insightful knowledge.
While it's not as specific as some other books (language specific references, compiler construction texts, etc), it is a great beginning and reference for a wide range of topics. The bibliography of this book is incredible. I have marked a large number of papers/books from the bib that I now want to read in full.
The bonus information on the CD is also very good, including all the source code from the book, extra sections, and links to other resources.
 Very Good Book
Overall, "Programming Language Pragmatics" (PLP) is a very good book. According to the Preface:
"It aims, quite simply, to be the most comprehensive and accurate languages text available, in a style that is engaging and accessible to the typical undergraduate....
At its core, PLP is a book about how programming languages work. Rather than enumerate the details of many different languages, it focuses on concepts that underlie all the languages the student is likely to encounter, illustrating those concepts with a variety of concrete examples, and exploring the tradeoffs that explain why different languages were designed in different ways."
I'm not knowledgeable enough to pass judgment on "the most comprehensive and accurate" part. But, I'm pretty happy about the book meeting the rest of those goals. I read through the book on my own and have only a few significant gripes:
- Chapters 2 (Programming Language Syntax) and 4 (Semantic Analysis) are tough to get through. They're basically trying to teach enough about Alphabets, Languages, Regular Expressions, Context-Free Grammars, Finite Automata and Push-Down Automata for the reader to understand what the rest of the book is based on. I've read Cohen's Introduction to Computer Theory, which is dedicated solely to this material and I still had some trouble. With an instructor in a class to walk through the things, it should be doable. But, for a person reading the book on his own, ugh.
- All of Section III: Alternative Programming Models, seems to depart from the format of the rest of the book (as noted in the Preface) where the author talks about the concepts and then how the different languages implement them. Instead, he focuses on the languages themselves and almost seems to be trying to cram a primer into his text. Since the section seems to be a special case, it wouldn't be so bad except that the languages covered are a bit out of the mainstream and so that degree of depth gets pretty unreadable at times. Again, with a professor around, things would be better.
- At a more pedagogical level, the author has a tendency to merely explain what his example Figures are doing in general terms. The problem is that a lot of the code/pseudocode involves fairly advanced structures in several languages (many of which most people won't have run across). It would have made things a lot easier if he had walked his way through each of those Figures line-by-line and explained what each line did. Once again, this wouldn't be that much of a problem in a normal teaching environment since a professor could do it.
Other than those three things, this is a very good and readable book. I rate it at four stars out of five.
Excellent coverage of language concepts
This is among my favorite computer science books. I read the first edition straight through from cover to cover, even though I had some prior knowledge of the subject. I have since purchased the second edition, which exceeds the high standards set by the first edition. Scott's book would have made the programming languages course I took as an undergraduate much more enlightening, had it existed at the time.
Great book.
As a software engineer, I tend to be picky about my books, but this one is very in depth and a good read. You will learn a lot about different programming languages, and why certain languages are better than others for solving different types of prroblems.
