An excellent introduction to C++ for competent C programmers. If you don't
already have a C++ book that you like, try this one.
Van der Linden, Peter. Expert C Programming: Deep C Secrets. Englewood Cliffs,
N.J.: Prentice-Hall, 1994.
Written by a member of Sun Microsystems' compiler development team, this
book helps to fill the gaps in knowledge between an ordinary C programmer
and a guru. Although not entirely necessary, an understanding of these
advanced topics can only make you a better embedded programmer. This
book is an excellent reference as well as an entertaining read.
Van Sickle, Ted. Programming Microcontrollers in C. Solana Beach, Calif.:
HighText Publications, 1994.
Like many of the embedded programming books that I've found, this one is
specific to a particular processor family. However, because the book is well
written and Motorola's microcontrollers are quite popular, some readers will
still find it useful.
Magazines and Conferences
Embedded Systems Programming
A monthly publication devoted specifically to the issues embedded software
developers face on the job. Every article and column is packed with practical
advice and written in a casual style familiar to readers of this and other
Nutshell Handbooks. I highly recommend that everyone reading this
sentence immediately put my book down and take a few minutes to sign up
for a free subscription at It usually
takes several months to get going, but is well worth the wait.
In addition, you might want to purchase a copy of the CD-ROM archive.
This searchable database contains hundreds of past articles and columns and
was an indispensable reference in the creation of this book. More
information is available at
Embedded Systems Conference
A technical conference hosted several times each year by the publishers of
the magazine just described. The conference has been running for about 10

years, and the number of exhibitors and attendees continues to grow each
year. The knowledge to be gained here far outweighs the cost of traveling to
the conference and attending the classes. I try to go as often as I can.
World Wide Web
Chip Directory (
An unbelievably large collection of information about common processors
and peripherals. This is not the only such site on the Web, but it is one of the
best maintained and it has links to many of the others.
CPU Info Center (
Tons of information about new and old processors alike. Includes a section
specifically about common embedded processors.
CRC Pitstop (
A site dedicated to information about CRC implementation, including Ross
Williams' "Painless Guide to CRC Error Detection Algorithms." The latter is
the most readable explanation of CRC calculations I've ever found.
Electronic Engineers' Toolbox (
Focused on embedded systems, real-time software development issues, and
Internet-enabling technologies, the "EE Toolbox" is designed to make your
job easier. The publishers of this site have identified, indexed, and
summarized thousands of relevant Internet resources and brought them all
together in one place.
Embedded Intel Architecture (
Intel's home page for their embedded processor line, including the 80188EB.
In addition to technical information about the hardware, there are also free
development and debugging tools and example source code listings.
news:comp.arch.embedded
A newsgroup devoted to many of the topics discussed in this book.
Discussions frequently involve software development tools and processes,
comparisons of commercial real-time operating systems, and suggestions for
processor selection criteria.

news:comp.realtime
Another good newsgroup for embedded systems discussion. This one tends
to focus more heavily on real-time scheduling issues, however, so not all of
the information is relevant. A list of FAQs from this group can be found at

Ideal as an introduction for beginners and a quick reference for advanced
programmers, Regular Expression Pocket Reference is a comprehensive guide to
regular expression APIs for C, Perl, PHP, Java, .NET, Python, vi, and the POSIX
regular expression libraries. This handy book offers programmers a complete
overview of the syntax and semantics of regular expressions, which are at the heart
of every text-processing application. When you've reached a sticking point and
need to get to a solution quickly, the new Regular Expression Pocket Reference is
the book you'll want to have.





Chapter 1. Regular Expression Pocket Reference
Regular expressions (known as regexps or regexes) are a way to describe text
through pattern matching. You might want to use regular expressions to validate
data, to pull pieces of text out of larger blocks, or to substitute new text for old
text.
Regular expression syntax defines a language you use to describe text. Today,
regular expressions are included in most programming languages as well as many
scripting languages, editors, applications, databases, and command-line tools. This
book aims to give quick access to the syntax and pattern-matching operations of
the most popular of these languages.

1.1 About This Book
This book starts with a general introduction to regular expressions. The first
section of this book describes and defines the constructs used in regular
expressions and establishes the common principles of pattern matching. The
remaining sections of the book are devoted to the syntax, features, and usage of
regular expressions in various implementations.
The implementations covered in this book are Perl, Java, .NET and C#, Python,
PCRE, PHP, the vi editor, JavaScript, and shell tools.
1.1.1 Conventions Used in This Book
The following typographical conventions are used in this book:
Italic

Used for emphasis, new terms, program names, and URLs
Constant width
Used for options, values, code fragments, and any text that should be typed
literally
Constant width italic
Used for text that should be replaced with user-supplied values
1.1.2 Acknowledgments
The world of regular expressions is complex and filled with nuance. Jeffrey Friedl
has written the definitive work on the subject, Mastering Regular Expressions
(O'Reilly), a work on which I relied heavily when writing this book. As a
convenience, this book provides page references to Mastering Regular
Expressions, Second Edition (MRE) for expanded discussion of regular expression
syntax and concepts.

This book simply would not have been written if Jeffrey Friedl had not blazed a
trail ahead of me. Additionally, I owe him many thanks for allowing me to reuse
the structure of his book and for his suggestions on improving this book. Nat
Torkington's early guidance raised the bar for this book. Philip Hazel, Ron
Hitchens, A.M. Kuchling, and Brad Merrill reviewed individual chapters. Linda
Mui saved my sanity and this book. Tim Allwine's constant regex questions helped
me solidify my knowledge of this topic. Thanks to Schuyler Erle and David Lents
for letting me bounce ideas off of them. Lastly, many thanks to Sarah Burcham for
her contributions to Section 1.11 and for providing the inspiration and opportunity
to work and write for O'Reilly.
