There is also a free online book, Beginning Perl, at the site of. Programming Perl, put out by O'Reilly Media, is a mainstay. You'll find forums and other resources, too. On the related site, Perl Monks, you'll find a lot of tutorials, written by aficionados and organized into categories like database programming and user interfaces. You won’t find in-depth resources here, though. You can write your first program – Hello World – as soon as you’ve downloaded Perl. The official Perl 5 site has a subdomain of learning resources. Interested in learning more about Perl? There are a lot of “authority sites” they appear separate but many are in some way affiliated with the Perl Foundation. There is more overhead on some tasks than there is with compiled languages. Perl is not as simple as some scripting languages - either to learn or to read. When is Perl not the best choice? If you are a website administrator or developer with more basic tasks like creating guest books and forums, you may find that it's more complicated than you need. Perl is used extensively in health informatics. The NASA Technical Reports Server relies on PERL. Perl is used in in a variety of other industries including the ground segment of space exploration. It is also used in programs that manage sensitive health care data.īioinformatics, meanwhile, has been Perl territory for over a decade. It is a go-to language for creating programs that do health care billing. Perl is also used to make quick batch modifications and to create Graphical User Interfaces. One common application of the language is to write bits of code that transfer data from one format to another. Perl is frequently described as a glue because it can get incompatible systems communicating. Perl eventually spawned other scripting languages like PHP ( Learn about the PHP Programming Language). The Comprehensive Perl Archive Network, or CPAN as it is commonly called, includes 114,498 modules written by more than 10,000 individuals.Ī number of other languages contain at least a pearl of Perl. It may have begun as a one man operation, but it’s now the work of thousands. Perl is now offered free under a license even more generous than GNU. Versions earlier than 5 have not been supported or used for a long time due to security issues. Currently Perl 5 and Perl 6 are both in usage they are considered separate languages and are under simultaneous development. Perl achieved fame - and, yes, a bit of infamy, while it was still quite a young computer language. 1989 brought version 3.0 and distribution under a GNU license. Version 2 introduced many new features including wait and sort operators and support for recursive subroutine calls. Hall's language was briefly known as RN it was Perl, though, by 1987 when Version 1.0 was introduced. Hall has referred to it as a "postmodern computer language" because it draws its wisdom from so many sources without necessarily giving allegiance to any. Over time, Perl evolved to include components of many computer languages, not just C and Unix. And so Hall needed something that would glue them together. C was good for some of his programming needs while Unix shells ( Learn about UNIX) were handy for others. Larry Hall, then a developer at Unisys, invented it while trying to synchronize information and generate reports. Its development goes back a long time: to 1986. Perl is not an acronym, but has sometimes been referred to as the Practical Extraction and Report Language.
