How to Write a Parser / Translator Using Lex / Yacc
These two can form two different passes of a Parser. The Lexical analysis can store all the recognized tokens in an intermediate file and give it to the Parser as an input. However it is more convenient to have the lexical Analyzer as a coroutine or a subroutine which the Parser calls whenever it requires a token.

Beginner's Guide to CGI Scripting with Perl
This page grows out of my own experience. When I started out on the Web I was new to Unix, and had no formal training as a programmer. I wanted to create dynamic pages for my Web site, though, and everyone said Perl was the way to go. They were right: It was the way to go. It sounds trite to say that "Perl changed my life," but that's basically what happenedwww.ewalkins.com
CGI Scripting in Perl
In order to run scripts you will need a web server running on your computer. The following information explains how to configure a web server and Perl on a Win32 computer in order to run CGI scripts. If you want information on setting up the same things on Unix/Linux there is a lot of information on the web, so I haven't written my own page about it.www.ewalkins.com
The CGI - Python FAQ
Try to run your script from the shell-prompt. Many times it is easier to find the location of a syntax error by running the script directly, as opposed to trying to find it from the error log. You may need to set several CGI environment variables in order for your script to run as far as the errorwww.ewalkins.com
Welcome! Python provides a portable, interpreted, interactive, object-oriented programming (OOP) language ideal for Common Gateway Interface (CGI) Web programming. Furthermore, its pairing of significant power and clear syntax makes Python an excellent instructional tool. Language features include moduleswww.ewalkins.com
Most often, CGI scripts live in the server's special cgi-bin directory. The HTTP server places all sorts of information about the request (such as the client's hostname, the requested URL, the query string, and lots of other goodies) in the script's shell environment, executes the script, and sends the script's output back to the client.www.ewalkins.com

Bison is a general-purpose parser generator that converts a grammar description for an LALR(1) context-free grammar into a C program to parse that grammar. Once you are proficient with Bison, you may use it to develop a wide range of language parsers, from those used in simple desk calculators to complex programming languages.www.ewalkins.com
Flex Man Pagewww.ewalkins.com
flex is a tool for generating scanners: programs which recognized lexical patterns in text. flex reads the given input files, or its standard input if no file names are given, for a description of a scanner to generate. The description is in the form of pairs of regular expressions and C code, called rules.www.ewalkins.com

A computer constructed from actual physical devices is termed an actual computer or hardware computer. From the programming point of view, it is the instruction set of the hardware that defines a machine. An operating system is built on top of a machine to manage access to the machine and to provide additional services.

This book gives a practical approach to understanding implementations of non-strict functional languages using lazy graph reduction. The book is intended to be a source of practical labwork material, to help make functional-language implementations `come alive', by helping the reader to develop, modify and experiment with some non-trivial compilers.www.ewalkins.com
Let's Build A Compiler - Jack Crenshaw
This fifteen-part series, written from 1988 to 1995, is a non-technical introduction to compiler construction. You can read the parts on-line or download them in a ZIP file.

Parsing Techniques A Practical Guide
This 320-page book treats parsing in its own right, in greater depth than is found in most computer science and linguistics books. It offers a clear, accessible, and thorough discussion of many different parsing techniques with their interrelations and applicabilities, including error recovery techniques.

Semantics with Applications
It is in fact mildly misleading that the collections are called "lecture" since a few collections are too short for a lecture (being supplemented by other material on the blackboard) and a few are too long (being split over lectures). However, the entire collection of transparencies have been used for about 26 lectures of 45 minutes each.

Partial Evaluation and Automatic Program Generation
The book Partial Evaluation and Automatic Program Generation gives a comprehensive presentation of partial evaluation: theory, techniques, and applications. It is suitable for self-study, and for graduate courses and advanced undergraduate courses on program transformation techniques.

Modern Compiler Design
The book consists conceptually of two parts. The first part covers the general compilation process, and contains three chapters based on the analysis/processing/synthesis paradigm: text analysis, context handling and code generation. The second part consists of four chapters, covering the paradigm-specific problemswww.ewalkins.com

Red Hat® Linux 6 Unleashed
The terms of the GNU GPL have allowed research institutions, universities, commercial enterprises, and hackers to develop and use Red Hat Linux and related technologies cooperatively without fear that their work would someday be controlled and restricted by a commercial vendor.www.ewalkins.com
Writing a book about a Linux application is something new. The publication of this book marks a new step for Linux books--until now, all the books about Linux have focused on the operating system. With the incredible growth of Linux, now approaching 8 million users, books about how to use Linux applications are becoming available--starting with this one.www.ewalkins.com
Slackware Linux Unleased
You'll find a CD-ROM at the back of the book that contains the Slackware 96 release of the Linux operating system. With this CD-ROM and this book, you should, I hope, be up and running with a UNIX-like operating system in a few hours.www.ewalkins.com
Sed By Example :: Part 1
In the UNIX world, we have a lot of options when it comes to editing files. Think of it -- vi, emacs, and jed come to mind, as well as many others. We all have our favorite editor (along with our favorite keybindings) that we have come to know and love.www.ewalkins.com

Sed By Example :: Part 2
Let's look at one of sed's most useful commands, the substitution command. Using it, we can replace a particular string or matched regular expression with another string. Here's an example of the most basic use of this command:www.ewalkins.com

Sed Man Page
The sed utility is a stream editor that reads one or more text files, makes editing changes according to a script of editing commands, and writes the results to standard output. The script is obtained from either the script operand string or a combination of the option-arguments from the -e script and -f script_file options.

Sed FAQs
Sed is affectionally known as a 'Stream Editor' which really means that it takes standard in and routes it out to standard out. Typically all input comes from the file that you are editing where it is splashed onto your screen or redirected to file. The command instructions that do the work tend to be inserted into a script that is read by sed. www.ewalkins.com
