Perl, or Practical Extraction and Reporting Language, is an open source programming language. It is often used for creating CGI programs and other web scripts. It was specifically designed for processing text, which makes it useful when writing web forms. If you want to use this popular programming language to help you process piles of text through your website, you’ve come to the right place.

Hashes

Apress Publishing 19932

Hashes in Perl aren't really that hard to understand; they're not that much harder than understanding how a phone book works. This article introduces you to hashes, what they do, and how to use them. It is excerpted from chapter five of the book Beginning Perl, written by James Lee (Apress; ISBN: 159059391X).

More Perl Bits

Peyton McCullough 40888

In the last article, I talked about the need to work at the bit level in Perl and in other languages. In order to understand bits, we first took a look at how binary numbers are represented in Perl, and then we took a look at two bitwise operators, AND and OR. In looking at the operators, we looked at their most common uses in programming. We also began to look at an algorithm for finding prime numbers, but we stopped upon seeing that there is no easy implementation, at least not without a knowledge of bits.

Perl, Bit by Bit

Peyton McCullough 55311

When you program, you're usually doing it at some distance from the bits and bytes that your computer understands. There never seems to be a need to think about bits. But believe it or not, learning about bits can be to your advantage for certain programming purposes. Perl provides operators for working with bits that let you leverage this knowledge.

Basic Charting with Perl

Peyton McCullough 62909

In programming, data manipulation is an everyday task. Programmers must be able to take raw data and perform some operation, or a set of operations, on that data to modify it. However, presenting data is also very important, both in programming and in other tasks. This article will cover one of the ways you can present data in Perl

Using Getopt::Long: More Command Line Options in Perl

Peyton McCullough 44289

In the last article, we took a look at command line options and how we could read them in Perl using the Getopt::Std module. For many simple applications, that article covers all that you need to make use of command line options. When you need more command line options, you can make use of the Getopt::Long module, which is the subject of this article.

Command Line Options in Perl: Using Getopt::Std

Peyton McCullough 79373

Unlike command line arguments, command line options can sometimes be a bit difficult to read; nevertheless, they can prove to be quite useful. This article explains what a command line option is, why you would use one, and how to process them in Perl. This article is the first of two parts.

Web Access with LWP

Peyton McCullough 30269

There are a number of ways you can retrieve information from the web. You can access it directly via a browser, or you can write a script that gets the information for you and delivers it in a form you can use. The LWP library for Perl can help you with the latter. Keep reading for a closer look.
