This book shows you how to use two Unix utilities, lex and yacc, in program development.

These tools help programmers build compilers and interpreters, but they also have a wider range of applications. The second edition contains completely revised tutorial sections for novice users and reference sections for advanced users. Yac edition is twice the size of the first and has an expanded index.

What it explains, it explains well. Unfortunately, there is much yaccc does not explain at all.

For example, how do I process conditional statements, how do I deal with functions and procedures, how do I incorporate classes in my language. The book needs a second volume which picks up where this one ends.

I like this book because it covered parsing and tokenizing from a deeper standpoint. Will re-read a few more times. They are also difficult to master.

lex & yacc, 2nd Edition

This book provides a good start. You may need to read it several times and work through the examples before things begin making sense. One person found this helpful. Very nice but hang on, because it is tough business. On another hand, if you want to build a compiler Yacc yet another compiler compiler and its companion lex lexical analyzer are primarily intended to allow quick and easy development of small special-purpose languages.

The common mistake is assuming that they are only useful for creating compilers for massively complex eccentric languages. This is not the case, though you could no doubt use them for such a purpose.

1. Lex and Yacc – lex & yacc, 2nd Edition [Book]

Lex and Yacc are commonly used together. Yacc uses a formal grammar to parse an input stream, something which lex cannot do using simple regular expressions since lex is limited to simple finite state automata. However, yacc cannot read from a simple input stream – it requires a series of tokens. Lex is often used to provide yacc with these tokens.

As a result, building an application in lex and yacc is often used as an exercise in classes on programming languages and the theory of computation to demonstrate key concepts. The book starts out building a simple character-driven calculator, and then moves annd to build a menu generation language that produces C code that uses the standard “curses” library to draw menus on the screen.

Some readers will dislike the fact that Lex and Yacc are only capable of generating C code. Thus, the logical conclusion is that you must be able to write C code in order to use these tools. Rather it is just a beginner’s guide. In summary, if you’ve never used lex or yacc before and think they might be useful tools for you, and you already know the C programming language, this is a handy book to have.

To me a great book flows into your mind, magically providing the information in the order you need it.

lex & yacc, 2nd Edition by Tony Mason, Doug Brown, John Levine

Of course it depends on whose reading it, but this book, though well worth the 96 cents bargain bin price I paid for it, does not build the constructs in my head the way I’d like. Authors should always proofread their books with novices, not the experts. Experts fill in the gaps as they read and don’t notice if the logic is missing a link. In chap 2, “Using Lex”, there is the sentence: Your program calls yylex to run the lexer. Does it return a token each time you call it?

Does it analyze all the input then return?

The text ignores this detail and merrily goes on into other details. The chapter is called “Using Lex”, but the authors omit how you use it! Of course you can scrounge around in the examples and finally root it out, but a book should paint a crystal clear picture, get you oriented, then drop in the le to build your understanding. The book looks so promising, sort of like the beauty of the original reioly C Programming Language” by Kernighan and Ritchie, but disappoints in it’s fragmented exposition.

I did take a compiler course with the “dragon book” years ago and write a parser, so I’m not totally in the dark, but I expected this book to lay the subject out in a much clearer way. But it is still a good book to have and read “offline”. I hope the authors take a crack at another edition and explain it all better. See all 29 reviews.
