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]

List of programming languages The aim of this list of programming languages is to include all notable programming languages in existence, both those in current use and historical ones, in alphabetical order, except for dialects of BASIC and esoteric programming languages. Note: Dialects of BASIC have been moved to the separate List of BASIC dialects. Note: This page does not list esoteric programming languages.

Perl Functions References Here is the list of all the important functions supported by standard Perl. C (programming language) C is one of the most widely used programming languages of all time,[8][9] and C compilers are available for the majority of available computer architectures and operating systems. C is an imperative (procedural) language. It was designed to be compiled using a relatively straightforward compiler, to provide low-level access to memory, to provide language constructs that map efficiently to machine instructions, and to require minimal run-time support. C was therefore useful for many applications that had formerly been coded in assembly language, such as in system programming. Despite its low-level capabilities, the language was designed to encourage cross-platform programming. A standards-compliant and portably written C program can be compiled for a very wide variety of computer platforms and operating systems with few changes to its source code. The C language also exhibits the following characteristics: The cover of the book, The C Programming Language For example:

Perl programming documentation Compiler A diagram of the operation of a typical multi-language, multi-target compiler A compiler is a computer program (or set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language, often having a binary form known as object code).[1] The most common reason for wanting to transform source code is to create an executable program. Program faults caused by incorrect compiler behavior can be very difficult to track down and work around; therefore, compiler implementors invest significant effort to ensure compiler correctness. The term compiler-compiler is sometimes used to refer to a parser generator, a tool often used to help create the lexer and parser. History[edit] Software for early computers was primarily written in assembly language. Towards the end of the 1950s, machine-independent programming languages were first proposed.

Perl Maven - for people who want to get the most out of programming in Perl Interpreter (computing) parse the source code and perform its behavior directlytranslate source code into some efficient intermediate representation and immediately execute thisexplicitly execute stored precompiled code[1] made by a compiler which is part of the interpreter system While interpretation and compilation are the two main means by which programming languages are implemented, they are not mutually exclusive, as most interpreting systems also perform some translation work, just like compilers. The terms "interpreted language" or "compiled language" signify that the canonical implementation of that language is an interpreter or a compiler, respectively. A high level language is ideally an abstraction independent of particular implementations. An illustration of the linking process. At the stage of compilation, in fact compilers act as interpreters and patch together such binary executables from an object code library defining which binary code sequence is named which command name.

Damien Learns Programming: Launch your Perl script from Notepad++ Today I am going to explain how you can be using Notepad++ to run Perl scripts. It can be convenient to launch your program directly from the editor's environment to quickly check that it compiles. Let's try and set up Notepad++ to launch the script from Wednesday's post. In the Plugins menu, you will find the NppExec plugin.Select Plugins>NppExec>Execute... You can also use the convenient F6 shortcut. Once the Execute... window is open, type in the following command:perl "$(FULL_CURRENT_PATH)"$(FULL_CURRENT_PATH) is an internal Notepad++ variable that contains the full path of the file currently open in the editor. You can save this command line and give it a meaningful name ('perl' for example). The output result is visible on the Console window. You can get rid of the "Process..." lines by selecting Plugins>NppExec>No Internal Message Also, if you want to repeat the previous command, you can just type Ctrl+F6. If you know more Notepad++ tips, I'd love to hear from you! Come on, try it!
