Emacs
Emacs (), originally named EMACS (an acronym for "Editor Macros"), is a family of text editors that are characterized by their extensibility. The manual for the most widely used variant, GNU Emacs, describes it as "the extensible, customizable, self-documenting, real-time display editor". Development of the first Emacs began in the mid-1970s, and work on GNU Emacs, directly descended from the original, is ongoing; its latest version is , released . Emacs has over 10,000 built-in commands and its user interface allows the user to combine these commands into macro (computer science), macros to automate work. Implementations of Emacs typically feature a dialect (computing), dialect of the Lisp (programming language), Lisp programming language, allowing users and developers to write new commands and applications for the editor. Extensions have been written to, among other things, manage Dired, files, Secure Shell, remote access, Gnus, e-mail, Org-mode, outlines, multimedia, Magit, Git ...

GNU Emacs
GNU Emacs is a text editor and suite of free software tools. Its development began in 1984 by GNU Project founder Richard Stallman, based on the Emacs editor developed for Unix operating systems. GNU Emacs has been a central component of the GNU project and a flagship project of the free software movement. The program's tagline is "the extensible self-documenting text editor." Most functionality in GNU Emacs is implemented in user-accessible Emacs Lisp, allowing deep extensibility directly by users and through community-contributed packages. Its built-in features include a file browser and editor (Dired), an advanced calculator (Calc), an email client and news reader (Gnus), a Language Server Protocol integration, and the productivity system Org-mode. A large community of users have contributed extensions such as the Git interface Magit, the Vim (text editor), Vim emulation layer Evil, several search frameworks, the window manager EXWM, and tools for working with a wide range of p ...

XEmacs
XEmacs is a graphical- and console-based text editor which runs on almost any Unix-like operating system as well as Microsoft Windows. XEmacs is a fork, based on a version of GNU Emacs from the late 1980s. Any user can download, use, and modify XEmacs as free software available under the GNU General Public License version 2 or any later version. History Between 1987 and 1993 significant delays occurred in bringing out a new version of GNU Emacs (presumed to be version 19). In the late 1980s, Richard P. Gabriel's Lucid Inc. faced a requirement to ship Emacs to support the Energize C++ IDE. So Lucid recruited a team to improve and extend the code, with the intention that their new version, released in 1991, would form the basis of GNU Emacs version 19. However, they did not have time to wait for their changes to be accepted by the Free Software Foundation (FSF). Lucid continued developing and maintaining their version of Emacs, while the FSF released version 19 of GNU Emacs a y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Editor War
The editor war is the rivalry between users of the Emacs and vi (now usually Vim, or more recently Neovim) text editors. The rivalry has become an enduring part of hacker culture and the free software community. The Emacs versus vi debate was one of the original "holy wars" conducted on Usenet groups. Since at least 1985, many flame wars have occurred between those insisting that their editor of choice is the paragon of editing perfection, and insulting the opposing group accordingly. Related battles have been fought over operating systems, programming languages, version control systems, and even source code indent style. Background , both Emacs and vi can lay claim to being among the longest-lived application programs of all time, as well as being the two most commonly used text editors on Linux and Unix. Many operating systems, especially Linux and BSD derivatives, bundle multiple text editors with the operating system to cater to user demand. For example, a default insta ...

Gnus
Gnus (), or Gnus Network User Services, is a message reader which is part of GNU Emacs. It supports reading and composing both e-mail and news and can also act as an RSS reader, web processor, and directory browser for both local and remote filesystems. Gnus blurs the distinction between news and e-mail, treating them both as "articles" that come from different sources. News articles are kept separate by group, and e-mail can be split into arbitrary groups, similar to folders in other mail readers. In addition, Gnus is able to use a number of web-based sources as inputs for its groups. Features Some Gnus features: * a range of backends that support any or all of: ** reading email from the local filesystem, or over a network via IMAP or POP3 ** reading web pages via an RSS feed ** treating a directory of files, either local or remote (via FTP or other method) as articles to browse ** reading Usenet News, including the Gmane and Gwene mail-to-news archives of mailing lists ** s ...

Dunnet (video Game)
''Dunnet'' is a surreal, cyberpunk text adventure written by Ron Schnell, based on a game he wrote in 1982. The name is derived from the first three letters of ''dungeon'' and the last three letters of ''ARPANET''. It was first written in Maclisp for the DECSYSTEM-20, then ported to Emacs Lisp in 1992. Since 1994 the game has shipped with GNU Emacs; it also has been included with XEmacs. The game has been recommended to writers considering writing interactive fiction. Plot The game starts out with the player standing at the end of a dirt road, but it turns to the surreal when players realize that they are actually walking around inside a Unix system, and teleporting themselves around the Arpanet. There are many subtle jokes in this game, and there are multiple ways of ending the game. Throughout the game the player moves through different areas and rooms trying to collect treasure to earn points. Legacy Dunnet is playable on any operating system with the Emacs editor. Emac ...

Magit
Magit ( or ) is an interface to the Git version control system, available as a GNU Emacs package written in Emacs Lisp. It is available through the MELPA package repository, on which it is the most-downloaded non-library package, with over 4.3 million downloads as of September 2024. Like many graphical user interfaces, Magit provides a visual interface to represent version control actions; however, it uses a keyboard-centric model, and also functions as a text-based user interface. The issue of key-memorization is mitigated through use of a popup menu which displays the actions available to the user — serving as a Mnemonics, mnemonic aid. History Magit was created by Marius Vollmer in 2008, with Jonas Bernoulli assuming the role of maintainer in 2013. Since its release, Magit has seen a high degree of Open-source software development, community involvement, with 350 individuals having contributed code to this free software project as of September 2020. In 2018 Magit under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Stallman
Richard Matthew Stallman ( ; born March 16, 1953), also known by his initials, rms, is an American free software movement activist and programmer. He campaigns for software to be distributed in such a manner that its users have the freedom to use, study, distribute, and modify that software. Software which ensures these freedoms is termed free software. Stallman launched the GNU Project, founded the Free Software Foundation (FSF) in October 1985, developed the GNU Compiler Collection and GNU Emacs, and wrote all versions of the GNU General Public License. Stallman launched the GNU Project in September 1983 to write a Unix-like computer operating system composed entirely of free software. With that he also launched the free software movement. He has been the GNU project's lead architect and organizer, and developed a number of pieces of widely used GNU software including among others, the GNU Compiler Collection, GNU Debugger, and GNU Emacs text editor. Stallman pioneered the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dired
Dired (for Directory Editor) is a computer program for editing file system directories. It typically runs inside the Emacs text editor as a specialized mode, though standalone versions have been written. Dired was the file manager, or visual editor of file system information. The first version of Dired was written as a stand-alone program independently in 1972 by Dave Lebling at Project MAC, and circa 1974 by Stan Kugell at the Stanford Artificial Intelligence Laboratory (SAIL). It was incorporated into GNU Emacs from the earliest versions, and re-implemented in C and C++ on other operating systems. When run in Emacs, dired displays an ls-like file listing in an Emacs buffer. The list can be navigated using standard navigation commands. Several Emacs Lisp scripts have been developed to extend Dired in Emacs. In combination with Tramp it is able to access remote file systems for editing files by means of SSH, FTP, telnet and many other protocols, as well as the capabil ...

Org-mode
Mode (also: ''org-mode''; ) is a mode for document editing, formatting, and organizing within the free software text editor GNU Emacs and its derivatives, designed for notes, planning, and authoring. The name is used to encompass plain text files ("org files") that include simple marks to indicate levels of a hierarchy (such as the outline of an essay, a topic list with subtopics, nested computer code, etc.), and an editor with functions that can read the markup and manipulate hierarchy elements (expand/hide elements, move blocks of elements, check off to-do list items, etc.). Org Mode was created by Carsten Dominik in 2003, originally to organize his own life and work, and since the first release numerous other users and developers have contributed to this free software package. Emacs has included Org Mode as a major mode by default since 2006. Bastien Guerry is the maintainer since 2010, in cooperation with an active development community. Since its success in Emacs, some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lisp (programming Language)
Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in the late 1950s, it is the second-oldest high-level programming language still in common use, after Fortran. Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket, and Clojure. Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though not originally derived from) the notation of Alonzo Church's lambda calculus. It quickly became a favored programming language for artificial intelligence (AI) research. As one of the earliest programming languages, Lisp pioneered many ideas in computer science, including tree data structures, automatic storage management, dynamic typing, conditionals, higher-order function ...

Daniel Weinreb
Daniel L. Weinreb (January 6, 1959 – September 7, 2012) was an American computer scientist and programmer, with significant work in the environment of the programming language Lisp. Early life Weinreb was born on January 6, 1959, in Brooklyn, New York, and was raised there by his parents, Herbert and Phyllis Weinreb. He had two brothers, Bill and David, and attended Saint Ann's School. Education Weinreb graduated from St. Ann's School in Brooklyn, New York in 1975. He attended the Massachusetts Institute of Technology (MIT) from 1975 to 1979 (starting at age 16), graduating with a B.S. in computer science and electrical engineering, where he and Mike McMahon wrote EINE and ZWEI, text editors for MIT Lisp machines. EINE made use of the windowing system of the Lisp machine, and thus is the first Emacs written for a graphical user interface (GUI). EINE was the second implementation of Emacs ever written, and the first implementation of Emacs in Lisp. Most of the notable subs ...

Text Editor
A text editor is a type of computer program that edits plain text. An example of such program is "notepad" software (e.g. Windows Notepad). Text editors are provided with operating systems and software development packages, and can be used to change files such as configuration files, documentation files and programming language source code. Plain text and rich text There are important differences between plain text (created and edited by text editors) and rich text (such as that created by word processors or desktop publishing software). Plain text exclusively consists of character representation. Each character is represented by a fixed-length sequence of one, two, or four bytes, or as a variable-length sequence of one to four bytes, in accordance to specific character encoding conventions, such as ASCII, ISO/IEC 2022, ISO/IEC 2022, Shift JIS, UTF-8, or UTF-16. These conventions define many printable characters, but also whitespace character, non-printing characters th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
