What are some facts about Perl?
Perl is a programming language. Perl is an interpreted programming language. Perl is very useful for shell scripts, application programming, and web applications. Perl is quite easy to learn. Perl can be, but does not have to be, object-oriented. Perl was created by Larry Wall. Perl has probably the best implementation of regular expressions in existence.
Is PERL an interpreted or compiled programming language?
Perl is both compiled and interpreted language. In the traditional sense, Perl is a pure interpreted language. The reference Perl program is a prototypical two-stage interpreter: when a Perl script is invoked via #!/bin/perl (or similar), the perl interpreter performs a language parsing on the source code, creating an internal (to the perl interpreter) representation of program, which is then translated into binary code for execution. Every invocation of a perl program requires this translation/interpretation to be completed. There are several projects which can take perl source code and compile it down to a binary executable (that is, bypass the whole repeated translate/interpret phase each time). However, these are NOT complete - even the best can only manage about 95% of the perl code available. That is, these perl compiler are incomplete implementations of the Perl language. They can be very useful, but are not complete substitutes for the Perl interpreter. The real answer is that Perl was designed to be an interpreted language from the start; attempts to turn Perl into a compiled language are faced with the difficulty of Perl's sprawling syntax and complete lack of design for compilation, and thus, struggle to implement all the languages features in a compiler.
What is the best scripting language?
This depends on your definition of best and the environment you need to support. Best to me means simple, powerful syntax. The environments are broadly: Internet Applications, General-Purpose Applications, Special-Purpose Applications. 1. For server-side scripting in the *NIX environment, it is difficult to beat the power of Perl. It combines the familiarity of C-syntax and the power of AWK. Very short programs can produce very comprehensive results. Perl was originally designed for processing text files. With the extensions that have been added as Perl developed, combined with the CPAN archives, this has extended Perl to almost all storage and presentation formats. PHP has become a more popular alternative in the past 10 years. It borrows heavily from Perl and other languages, as Perl did. Perl is a preferred choice, in my opinion. Server-side scripting involves using the scripts to generate other code that your browser receives for final execution. In essence this is a two-pass process. 2. For client-side scripting JavaScript is the most widely supported. It is an incredibly flexible language. You can easily chain several results together. There are many alternatives that are gaining significant numbers of users. Ruby and Python are the most notable. JavaScript is very powerful, once the simple syntax are mastered. 3. For scripting that is not part of an Internet application, Perl is available in *NIX, Windows, and many other environments. If your application is Windows-only, C# is evolving to be a preferred language for many. In my experience it has a way to go to be as easy to use and reliable as it is intended to be. 4. For special, often more technical, applications you are best advised to look at special-purpose languages. Some of these can save you a lot of time over more general purpose scripting languages. For example, Haskell for functional programming. Perl 6 is using this to develop the Perl 6 compiler. A good, open-source editor to explore a lot of these scripting languages, is Komodo from Activestate. They support dozens of languages with code highlighting and syntax checking. It is free. They keep it very fresh with frequent updates. It includes extension creation tools 'a la' Firefox, and a library of user contributions. If you get into participating in open source projects as a contributor, you may want to look into the Eclipse SDK for expanded scope.
Where can one find information about Learning Perl?
There are a number of sites that provide information about how to learn the Perl programming language. They include Learn Perl, Learning Perl and Perl Tutorial Hub. Amazon and other good booksellers have a wide range of Perl books available.
Difference between perl scripting and shell scripting?
Perl is a scripting language. It is not, however, a shell scripting language because Perl is not a shell program. A shell program is one that usually interacts with a user and provides certain user interface abilities. Perl was not designed for that purpose. You can certainly program a shell to operate in various fashions. A shell script is usually provided for redundant tasks and series of commands, unattended operation, and so forth. Perl is a "kitchen sink" of ways to interact with data, databases, networks, and so forth. It is a great language for manipulating text in various ways.
Give two example of server side scripting language?
PHP Perl ASP
How use perl in bioinformatics?
Perl is a powerful and flexible scripting programming language, making it very helpful for manipulating data in bioinformatics research.
What has the author Harlan A Carvey written?
Harlan A. Carvey has written: 'Perl scripting for Windows security' -- subject(s): Perl (Computer program language), Computer security
Can CGI scripting be done in notepad?
Yes. CGI scripting can be done in notepad, since CGI scripting is just the scripting of normal programming languages, like Python and Perl.
Are scripting language widely used to add dynamic content to webpages?
There are PHP, Coldfusion, Ruby, Python or Perl to think of the most common ones.
List some alternate web scripting languages to PHP?
Ruby, Python, Perl
When was Perl Data Language created?
Perl Data Language was created in 1996.
Can you have PHP and PERL running on the same server and on the same website?
Yes, it is very easy to run PHP and Perl together on the same server, and even the same website. However, if you intend to use multiple applications written in different scripting languages, but have the potential for your site to eventually need complete integration, it is advisable to use applications written in only one scripting language.
Is PHP a completely object oriented language?
It depends on which language to you , is "Not" completely Object Oriented. To us PHP is a server scripting language like any other language ASP,CGI,PERL each. Orientation is the views of the users of the engines. It is not the view at the point of source or origin.
