Hacking Perl in Nightclubs
I've found the experiences of dancing and programming to have a great deal in common. With both I am immersed in an abstract world of animated structures, building up and breaking down many times before finally reaching a conclusion. Indeed, when the operation of even the dullest data-munging computer program is visualized, for example in a debugger, it does seem to be dancing around its loops and conditions -- moving in patterns through time.
In other words, a musical score is a kind of source code, and a musical performance is a kind of running program. When you play from a musical score or run a program you are bringing instructions to life.

Finding Installed Perl Modules
In working with numerous servers, some my own and many under client ownership, I bump into interesting issues to tackle (yep, this is obvious I know, we all do!). As most of us do now when stumped, a first resort is to Google the problem and see who has already resolved it. |
Just a few weeks ago I was wrestling with a web-based Perl application problem for some advanced scripts that I had not authored and became convinced it was related to modules (does anyone else get flustered with obfuscated Perl error messages?!).

Perl cornucopia
It's been almost a month now since our weekly Perl newsletter went the way of the T-Rex and the Dodo bird. We figured right about now you'd be in need of a pre-Thanksgiving fix, so we pulled together the best of James Brown's unpublished Perl tips. We hope you enjoy these little morsels of Perl goodness. They go great either before or after you stuff yourself with turkey and pumpkin pie.
Perl’s glob operator makes it easy to find all files that match a given wildcard pattern.
The glob operator implements the same filename expansions that the standard Unix C shell (/bin/csh) would do. This allows you more complex options in matching filenames.

Creating a mailing list using Perl
In the last article, we examined how it was possible to read and write to a file stored on the server. I mentioned that this was the basis behind saving state on a server and that numerous common activities on the Internet involve using files on the server in order to work. These included guestbooks, feedback forms, and many others.
This article will take a look at one of the more common activities on the web - a mailing list. Many websites (including irt.org) use mailing lists to let visitors know when the site is updated, removing the uncessary burden of having to return day after day only to be greeted with old content. These mailing lists typically have some sort of front end that lets a user enter his or her email address. A CGI script then accepts this address and adds it to either a text file or database on the server.

Getting Started with the Perl Template Toolkit
This article compares the Template Toolkit to other templating systems such as HTML::Mason and HTML::Template, describes how to install it, then shows you what templates look like and how to process them. (From the book, Perl Template Toolkit, O'Reilly Media, ISBN: 0596004761, by Darren Chamberlain, Dave Cross and Andy Wardley.)
The Template Toolkit is an all-Perl template processing system. Unlike many other Perl templating systems, it is as proficient at producing HTML as it is at producing XML, PDF, or any other output format. It has its own simple templating language, so templates can be written and edited by people who do not know Perl. And it supports command-line, modular, CGI, and mod_perl operation.
