Perl Though Perl is not officially an acronym,[5] there are various backronyms in use, such as: Practical Extraction and Reporting Language.[6] Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier.[7] Since then, it has undergone many changes and revisions. The latest major stable revision of Perl 5 is 5.18, released in May 2013. Perl 6, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from one another. History[edit] Early versions[edit] Wall began work on Perl in 1987, while working as a programmer at Unisys,[9] and released version 1.0 to the comp.sources.misc newsgroup on December 18, 1987.[14] The language expanded rapidly over the next few years. Perl 2, released in 1988, featured a better regular expression engine. Early Perl 5[edit] 2000–present[edit] Name[edit]
Welcome - Learn Python - Free Interactive Python Tutorial The XML Programming Language Click below to go directly to a specific section: History| Significant Language Features| Areas of Application| Sample Programs| Related Links| Printed References| Acknowledgements History XML, which stands for Extensible Markup Language, is a language similar to HTML used for creating arbitrarily-structured documents and web pages. The language is a filtered version of SGML, Standard Generalized Mark-Up Language, but more suited for web delivery with less overhead common with SGML. Unlike HTML, XML specifies no pre-defined tags. Significant Language Features XML files are written in ASCII text, so the information contained within an XML document is exchangeable between otherwise incompatible systems. The syntax of XML is completely ambiguous and really cannot be standardized. Since it is a text file, it can be viewed in any text editor. Areas of Application XML's biggest area of application is the organization of data within an intranet. Sample Programs An Invoice in XML Related Links

XML.com Getting Started with XML Programming April 21, 1999 If you're new to programming with XML, you may be wondering how to get started. The benefits of using XML to store structured data may be obvious, but once you've got some data in XML, how do you get it back out? In this article, we'll explore several alternatives and look at some concrete solutions in Perl. We're going to build a simple text processing application that uses XML to store user preferences and other configuration data. Reading configuration files Many applications need to store user preferences and other sorts of configuration information. Most programmers have probably written code to process text files like this at one time or another. Example 1. [section1] name1=value1 name2=value2 [section2] someothername=someothervalue In this article, I'm going to propose an XML version of the configuration file format (see Example 2), and explore several ways to get information out of files in this format using Perl. Example 2.
JavaScript: The World's Most Misunderstood Programming Language Douglas Crockford www.crockford.com JavaScript, aka Mocha, aka LiveScript, aka JScript, aka ECMAScript, is one of the world's most popular programming languages. Virtually every personal computer in the world has at least one JavaScript interpreter installed on it and in active use. JavaScript's popularity is due entirely to its role as the scripting language of the WWW. Despite its popularity, few know that JavaScript is a very nice dynamic object-oriented general-purpose programming language. How can this be a secret? The Name The Java- prefix suggests that JavaScript is somehow related to Java, that it is a subset or less capable version of Java. JavaScript has a syntactic similarity to Java, much as Java has to C. JavaScript was not developed at Sun Microsystems, the home of Java. The -Script suffix suggests that it is not a real programming language, that a scripting language is less than a programming language.

JavaScript JavaScript is classified as a prototype-based scripting language with dynamic typing and first-class functions. This mix of features makes it a multi-paradigm language, supporting object-oriented,[6] imperative, and functional[1][7] programming styles. JavaScript has been standardized in the ECMAScript language specification. History[edit] Beginnings at Netscape[edit] JavaScript was originally developed by Brendan Eich, while working for Netscape Communications Corporation. Although it was developed under the name Mocha, the language was officially called LiveScript when it first shipped in beta releases of Netscape Navigator 2.0 in September 1995, but it was renamed JavaScript[10] when it was deployed in the Netscape browser version 2.0B3.[11] The change of name from LiveScript to JavaScript roughly coincided with Netscape adding support for Java technology in its Netscape Navigator web browser.

They run on almost all platforms in existence without recompilation. support for variable number of function arguments. have the ability to freeze live objects in a string representation (for storing arbitrary objects on disk, moving them over the network, etc); they can then be converted back to identical objects with data intact.

HTML HTML or HyperText Markup Language is the standard markup language used to create web pages. HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>). HTML tags most commonly come in pairs like <h1>and </h1>, although some tags represent empty elements and so are unpaired, for example <img>. The first tag in a pair is the start tag, and the second tag is the end tag (they are also called opening tags and closing tags). The purpose of a web browser is to read HTML documents and compose them into visible or audible web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page. Web browsers can also refer to Cascading Style Sheets (CSS) to define the look and layout of text and other material.

PHP Scripting language created in 1994 PHP is a general-purpose scripting language geared towards web development.[8] It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1993 and released in 1995.[9][10] The PHP reference implementation is now produced by the PHP Group.[11] PHP was originally an abbreviation of Personal Home Page,[12][13] but it now stands for the recursive initialism PHP: Hypertext Preprocessor.[14] The standard PHP interpreter, powered by the Zend Engine, is free software released under the PHP License. PHP has been widely ported and can be deployed on most web servers on a variety of operating systems and platforms.[17] The PHP language has evolved without a written formal specification or standard, with the original implementation acting as the de facto standard that other implementations aimed to follow.

PHP Programming PHP is a scripting language designed to fill the gap between SSI (Server Side Includes) and Perl, intended for the web environment. Its principal application is the implementation of web pages having dynamic content. PHP has gained quite a following in recent times, and it is one of the frontrunners in the Open Source software movement. Its popularity derives from its C-like syntax, and its simplicity. PHP is currently divided into two major versions: PHP 4 and PHP 5, although PHP 4 is deprecated and is no longer developed or supplied with critical bug fixes. PHP 6 is currently under development. If you've ever been to a website that prompts you to login, you've probably encountered a server-side scripting language. Basically, PHP allows a static webpage to become dynamic. Before you embark on the wonderful journey of Server Side Processing, it is recommended that you have a basic understanding of the HyperText Markup Language.
