Emacs Modes
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 macros to automate work. Implementations of Emacs typically feature a dialect of the 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 files, remote access, e-mail, outlines, multimedia, Git integration, RSS feeds, and collaborative editing, as well as implementations of ''ELIZA'', ''Pong'', '' Conway's L ...

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] |
Snake (video Game Genre)
Snake is a video game genre, genre of action game, action video games where the player maneuvers the end of a growing line, often themed as a snake. The player must keep the snake from colliding with both other obstacles and itself, which gets harder as the snake lengthens. The genre originated in the 1976 competitive arcade video game ''Blockade (video game), Blockade'' from Gremlin Industries where the goal is to survive longer than the other player. ''Blockade'' and the initial wave of clones that followed were purely abstract and did not use ''snake'' terminology. The concept evolved into a single-player variant where a line with a head and tail gets longer with each piece of food eaten—often apples or eggs—increasing the likelihood of self-collision. The simplicity and low technical requirements of snake games have resulted in hundreds of versions, some of which have the word ''snake'' or ''worm'' in the title. The 1982 ''Tron (video game), Tron'' arcade video game, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

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 ...

Vi (text Editor)
vi (pronounced as two letters, ) is a screen-oriented text editor originally created for the Unix operating system. The portable subset of the behavior of vi and programs based on it, and the ex (text editor), ex editor language supported within these programs, is described by (and thus standardized by) the Single Unix Specification and POSIX. The original code for vi was written by Bill Joy in 1976 as the visual mode (user interface), mode for the ex line editor that Joy had written with Chuck Haley. Joy's ex 1.1 was released as part of the first Berkeley Software Distribution (BSD) Unix release in March 1978. It was not until version 2.0 of ex, released as part of Second BSD in May 1979 that the editor was installed under the name "vi" (which took users straight into ex's visual mode), and the name by which it is known today. Some current implementations of vi can trace their source code ancestry to Bill Joy; others are completely new, largely compatible reimplementations. Th ...

Fork (software Development)
In software development, a fork is a codebase that is created by duplicating an existing codebase and, generally, is subsequently modified independently of the original. Software built from a fork initially has identical behavior as software built from the original code, but as the source code is increasingly modified, the resulting software tends to have increasingly different behavior compared to the original. A fork is a form of branching, but generally involves storing the forked files separately from the original; not in the repository. Reasons for forking a codebase include user preference, stagnated or discontinued development of the original software or a schism in the developer community. Forking proprietary software (such as Unix) is prohibited by copyright law without explicit permission, but free and open-source software, by definition, may be forked without permission. Etymology The word ''fork'' has been used to mean "to divide in branches, go separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
GNU Project
The GNU Project ( ) is a free software, mass collaboration project announced by Richard Stallman on September 27, 1983. Its goal is to give computer users freedom and control in their use of their computers and Computer hardware, computing devices by collaboratively developing and publishing software that gives everyone the rights to freely run the software, copy and distribute it, study it, and modify it. GNU software grants these rights in GNU General Public License, its license. In order to ensure that the ''entire'' software of a computer grants its users all freedom rights (use, share, study, modify), even the most fundamental and important part, the operating system (including all its numerous utility programs) needed to be free software. Stallman decided to call this operating system ''GNU'' (a recursive acronym meaning "''GNU's not Unix!''"), basing its design on that of Unix, a proprietary operating system. According to its manifesto, the founding goal of the project w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
