PERL HELP, PERL PROGRAMMING, PERL CODE, PERL TUTORIALS, PERL DEVELOPMENT

This marks the finale of our coverage of text in Perl (until we get into some more of the advanced Perl features at any rate). We left off with the here document and how to use it to display text exactly as we type it in, using a Mark Twain poem that he had written for his daughter's tombstone (which interestingly enough was a rewrite of another poet's poem). We also learned a little bit about ASCII and the values as they pertain to text, showcasing the 93 visible characters.

In our last article we introduced you to using text in Perl. By the time we were done, there was text everywhere. But that's okay. In this tutorial we will learn to clean that text up and put it in its place. So roll up those sleeves and prepare to get organized. No more sloppy text for you!

There are lots of way to express yourself, but with programming languages the simplest way to do that is usually text. This tutorial will walk you through ways to make text work for you in Perl. It's the first of a three-part series, and since (as usual) we have a lot of ground to cover, let's get started.

In our last tutorial we left off on the topic of creating files and manipulating the data therein. In this article we will discuss how to append to a file and how to write to a file. If there is time, we will also discuss working with file checks.

In our last series of tutorials we worked with Conditionals and Loops to create some basic Perl programs. This time around we are going to be working with files. Text files, CGI files, PL files, boiled files, fried files, Files Benedict, steamed Files. Okay, so I was kidding about the steamed Files.

While Perl truly is the programming language of the slacker, the bored, and the (okay I'll say it with great lamentation) creative, it is also a harsh mistress. But let's face it: as a computer programmer, you are luck to have a mistress at all. So chin up. Perl doesn't just freely give you love. There are conditions, or, more precisely, conditionals, which is the topic of this fourth part in a series.

So, when we last left off, I left you lost in a tumultuous sea of data types, variables, and strings. Fortunately for you, you have the black Perl, the world's fastest ship and a magical compass to point you in the right direction. So let's prepare to sail, er, study, and mind the shoals.

In the last article, you learned how to install Perl. It wouldn't make a lot of sense to install it on your computer if you never did anything with it, now would it? In this article, you'll take your first steps to becoming part of a wild and crazy breed -- a Perl programmer.

Possessed of a name that stands for "Practical Extraction and Report Language" -- or maybe not -- Perl has expanded from its humble beginnings to let users perform a wide variety of tasks. Before you can use it to do any of those tasks, however, you must install it. That is the focus of this article, the first in a series that will teach you the basics of Perl programming.

In this final part of a three part series covering subroutines in Perl, we will discuss returns and return values, as well as prototypes.

In this second part of a three-part series covering subroutines in Perl, you will learn about missing arguments, default argument values, and more.

Subroutines let programmers extend the Perl language...at least in theory. There are certain pitfalls for which you need to be alert. This article, the first of three parts, will warn you about those pitfalls and help you avoid them.

In this article, you will learn how to find out useful information about files in Perl. It is excerpted from chapter 11 of the book Learning Perl, Fourth Edition, written by Randal L.

This article covers some API methods of the XML::XSLT module and shows you how to create a new XML file without needing to do any Perl programming. You will also learn how to transform a dynamically generated XML data structure.

Perl may not be as well known as some of the other languages, but it boasts a powerful library of packages and modules that everyone can use to work with XML. In this article, Harish Kamath explains how to get started with the "XML::XSLT" package that allows you to transform XML documents by using XSLT style sheets using Perl.
