Perl,
the programming language, is feature-rich as well as highly capable. It
can be said to be a much used language for web applications, which has
been used for quite some time now. It can run over a large number of
platforms, whether mainframes or portables. It may be used for both
large scale development projects as well as rapid prototyping. Ever
since its inception, it has been adopted quickly and has become a
well-loved language. There are a number of features as well as
advantages that can be said to have contributed to this popularity.
Easily extendible- More
than 25,000 open sources modules are available from CPAN or
Comprehensive Perl Archive Network. This well maintained central
repository contains virtually innumerable Perl Modules which may be used
for including in Perl scripts or programs. These code libraries have
been created for almost all programming requirements, preventing us from
reinventing things.
Functional, procedural as well as object-oriented- Functional, object-oriented as well as procedural programming is supported by it.
Mission critical - Perl web programming performs with precision, making it apt for using in mission critical projects, both in private as well as public sectors.
Textmanipulation-
Powerful tools are included for the processing of text, which make it
perfect for functioning with XML, HTML, PDF as well as other document
formats or natural and mark-up languages.
Database integration- Third
party databases are supported by the DBI or database integration
interface of Perl. The databases supported include MySQL, Postgres,
Oracle, Sybase as well as many others.
Open Source-
The Open Source software is distributed under GNU General Public
License or Artistic License; due to this, it is easy to adopt. If some
problem arises then it becomes easy to find solutions since its open
source nature makes it easy to get in touch with experienced
professionals for help from forums, etc.
Embeddable- Other systems like database servers as well as web servers may reap the benefits of being embedded with Perl interpreter.
C++/C library interface- Perl can interface with external C++/C libraries through SWIG or XS.
Ideal programming language for web- Perl
can be said to be an ideal programming language for web because of its
rapid development cycle as well as text manipulation capabilities.
Web modules- Thousands
of web modules are offered by CPAN so that almost all tasks that are
needed for you to be accomplished will become easier. It can make things
like image or URL manipulation, Amazon EC2 APIs, etc., much smoother.
Web frameworks- Various web frameworks can be written in the language, amongst which the leader is Catalyst.
Encryption capable- Encrypted web data can be handled by the language and that includes e-commerce transactions.
Apache embedded- Web
servers may be embedded with the language which may help in the
speeding up of the processing by 2000% even. Apache web server can embed
Perl interpreter by virtue of mod perl.
Duct taping internet- It
is majorly known as the internet’s duct tape. But there are many huge
web based application which can be written just in this language.
Easy to adopt- The
syntax has a lot of similarities with C#, C++/C or Java which makes it
very easy for programmers to move from those languages to Perl. Another
advantage is that different ways can be used for the functioning of same
thing, which sets it apart from other languages.
Currently,
the language is facing a decline due to the emergence of many improved
languages which has led many people to dub this language as obsolete.
But despite their arguments, the possibilities of Perl are by no means,
completely over. It has a future but the language may be meant for
limited audience. Today, it is best suited for those people who have
worked with it from its very inception and are used to its quirky
stylistic conventions. New users may not be successfully attracted to it
but old users may still be able to reap benefits from the features.
