It is freely available (in PostScript format) on the Internet. On the other hand, computers tend to get faster and faster, and writing something in Perl instead of C tends to save your time.Ĭitat:The Perl Reference Guide is a typeset quick reference guide to Larry Wall's Perl program, version 5.004. Thus, the execution of a Perl script tends to use more CPU time than a corresponding C program, for instance. Perl is implemented as an interpreted (not compiled) language. And if you haven't used such utilities but have started thinking you might have need for them, then perhaps what you really need to learn is Perl instead of all kinds of futilities. If you have used shell scripts or awk or sed or similar (Unix) utilities for various purposes, you will find that you can normally use Perl for those and many other purposes, and the code tends to be more compact.
Programs written in Perl are called Perl scripts, whereas the term the perl program refers to the system program named perl for executing Perl scripts. But Perl provides a large number of tools for quite complicated problems, including systems programming. A typical simple use of Perl would be for extracting information from a text file and printing out a report or for converting a text file into another form. In presenting Perl features, I tried to find examples that are interesting in their own right, and that encourage the reader to explore Perl's features.Ĭitat:Perl is a programming language which can be used for a large variety of tasks. I wanted to bring it closer to the center of focus (although I am anything but an object-oriented bigot). * In many Perl books, object-oriented programming is treated as an optional feature for advanced programming. Many of the Perl programs I have seen are written in a quick-and-dirty style I wanted to see if the style I have developed in other languages can translate. * I want a book that emphasizes good programming style in Perl. I'm sick of reading about the precedence of operators I want to know how to do the fun stuff. * I want a book that gets through the basics as quickly as possible. * I want a book for people who already know how to program in another language, but don't know Perl. You may also want to join the Extreme Perl Group at Yahoo! Groups to discuss Extreme Programming with Perl.Ĭitat:Do we really need another Perl book? Well obviously I think so, and here's why: Please send me your suggestions, questions, etc.
