Perldoc
''Perl Programming Documentation'', also called ''perldoc'', is the name of the user manual for the Perl 5 programming language. It is available in several different formats, including online in HTML and PDF. The documentation is bundled with Perl in its own format, known as Plain Old Documentation (pod). Some distributions, such as Strawberry Perl, include the documentation in HTML, PDF, and pod formats. perldoc is also the name of the Perl command that provides "access to all the documentation that comes with Perl", from the command line.

Perl 5
Perl is a family of two high-level, general-purpose, interpreted, dynamic programming languages. "Perl" refers to Perl 5, but from 2000 to 2019 it also referred to its redesigned "sister language", Perl 6, before the latter's name was officially changed to Raku in October 2019. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Raku, 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 each other. The Perl languages borrow features from other programming languages including C, sh, AWK, and sed; They provide text processing facilities without the arbitrary data-len ...

User Manual
A user guide, also commonly known as a user manual, is intended to assist users in using a particular product, service or application. It's usually written by a technician, product developer, or a company's customer service staff. Most user guides contain both a written guide and associated images. In the case of computer applications, it is usual to include screenshots of the human-machine interface(s), and hardware manuals often include clear, simplified diagrams. The language used is matched to the intended audience, with jargon kept to a minimum or explained thoroughly. Contents of a user manual The sections of a user manual often include: *A cover page *A title page and copyright page *A preface, containing details of related documents and information on how to navigate the user guide *A contents page *A Purpose section. This should be an overview rather than detail the objective of the document *An Audience section to explicitly state who is the intended audience who is r ...

Programming Language
A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning), which are usually defined by a formal language. Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard) while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common. Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming languages. Definitions There are many considerations when defining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HTML
The HyperText Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. HTML elements are delineated by ''tags'', written using angle brackets. Tags such as and directly introduce content into the page. Other tags such as sur ...

Portable Document Format
Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems.Adobe Systems IncorporatedPDF Reference, Sixth edition, version 1.23 (53 MB) Nov 2006, p. 33. Archiv/ref> Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991. PDF was standardized as ISO 32000 in 2008. The last edition as ISO 32000-2:2020 was published in December 2020. PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media (including video ...

Software Documentation
Software documentation is written text or illustration that accompanies computer software or is embedded in the source code. The documentation either explains how the software operates or how to use it, and may mean different things to people in different roles. Documentation is an important part of software engineering. Types of documentation include: * Requirements – Statements that identify attributes, capabilities, characteristics, or qualities of a system. This is the foundation for what will be or has been implemented. * Architecture/Design – Overview of software. Includes relations to an environment and construction principles to be used in design of software components. * Technical – Documentation of code, algorithms, interfaces, and APIs. * End user – Manuals for the end-user, system administrators and support staff. * Marketing – How to market the product and analysis of the market demand. Requirements documentation Requirements documentation is the des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plain Old Documentation
Plain Old Documentation (pod) is a lightweight markup language used to document the Perl programming language as well as Perl modules and programs. Design Pod is designed to be a simple, clean language with just enough syntax to be useful. It purposefully does not include mechanisms for fonts, images, colors or tables. Some of its goals are: * Easy to parse * Easy to convert to other formats, such as XML, TeX or Markdown * Easy to incorporate sample code * Easy to read without a pod formatter (i.e. in its source-code form) * Easy to write in An extended version of pod that supports tables and footnotes called PseudoPOD has been used by O'Reilly & Associates to produce several Perl books, most notably '' Programming Perl'' by Larry Wall, Tom Christiansen, and Jon Orwant. Pod makes it easy to write manual pages, which are well suited to user-oriented documents. In contrast, other documentation systems, such as Python's Docstring or Java's Javadoc, though they can be used fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Distribution (software)
Software distribution is the process of delivering software to the end user. A distro is a collection of software components built, assembled and configured so that it can essentially be used "as is". It is often the closest thing to turnkey form of free software. A distro may take the form of a ''binary distribution'', with an executable installer which can be downloaded from the Internet. Examples range from whole operating system distributions to server and interpreter distributions (for example WAMP installers). ''Software distribution'' can also refer to careware and donateware. In recent years, the term has come to refer to nearly any "finished" software (i.e. something that is more or less ready for its intended use, whether as a complete system or a component of a larger system) that is assembled primarily from open source components. Examples of distros Examples of software distributions include BSD-based distros (such as FreeBSD, NetBSD, OpenBSD, and DragonflyBS ...

Strawberry Perl
Strawberry Perl is a distribution of the Perl programming language for the Microsoft Windows platform. Additionally, strawberry contains a fully featured Mingw-w64 C/C++ compiler with many libraries included. While most other distributions rely on the user having software development tools already set up to install certain Perl components, Strawberry Perl ships with the most commonly used tools preconfigured and packaged. It is a dramatic departure from other Perl distributions, and has influenced other distributions (such as its primary rival, the freely available but closed source ActivePerl distribution released by ActiveState) to provide such development tools in their own distribution. Rationale Through the CPAN, Perl users can download any of a vast number of prepackaged modules. Many of these modules can be installed in any Perl environment; however, certain modules (XS modules) require a working C compiler and development environment to install successfully. Most Perl d ...

Command Line
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform. In some cases the invocation is conditional based on conditions established by the user or previous executables. Such access was first provided by computer terminals starting in the mid-1960s. This provided an interactive environment not available with punched cards or other input methods. Today, many users rely upon graphical user interfaces and menu-driven interactions. However, some programming and maintenance tasks may not have a graphical user interface and use a command line. Alternatives to the command-line interface include text-based user interface menus (for example, IBM AIX SMIT), keyboard shortcuts, and various desktop metaphors centered on the pointer (usu ...

Outline Of Perl
The following outline is provided as an overview of and topical guide to the Perl programming language: Perl – high-level, general-purpose, interpreted, multi-paradigm, dynamic programming language. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions and become widely popular amongst programmers. Larry Wall continues to oversee development of Raku. Note that Perl and Raku are receiving ongoing development, therefore making Perl a family of programming languages. It stands for Practical Extraction and Reporting Language which processes data using pattern matching technique. What ''type'' of thing is Perl? * Perl can be described as all of the following ''types'' of things: ** Family of programming languages – a programming language is an artificial language designed to communicate instructions to a machine, particularly a comput ...
