GNU Emacs is the most popular and most ported Emacs text editor. It was created by GNU Project founder Richard Stallman. In common with other varieties of Emacs, GNU Emacs is extensible using a Turing complete programming language. GNU Emacs has been called "the most powerful text editor available today." With proper support from the underlying system, GNU Emacs is able to display files in multiple character sets, and has been able to simultaneously display most human languages since at least 1999.〔(【引用サイトリンク】title=Alphabet Soup: The Internationalization of Linux, Part 1 Linux Journal March 1999 )〕 Throughout its history, GNU Emacs has been a central component of the GNU project, and a flagship of the free software movement. The tag line for GNU Emacs is "the extensible self-documenting text editor". == History == In 1976, Stallman wrote the first Emacs (“Editor MACroS”), and later in 1984 Richard Stallman began work on GNU Emacs, to produce a free software alternative to the proprietary Gosling Emacs. GNU Emacs was initially based on Gosling Emacs, but Stallman's replacement of its Mocklisp interpreter with a true Lisp interpreter required that nearly all of its code be rewritten. This became the first program released by the nascent GNU Project. GNU Emacs is written in C and provides Emacs Lisp, also implemented in C, as an extension language. Version 13, the first public release, was made on March 20, 1985. The first widely distributed version of GNU Emacs was version 15.34, released later in 1985. Early versions of GNU Emacs were numbered as "1.x.x," with the initial digit denoting the version of the C core. The "1" was dropped after version 1.12 as it was thought that the major number would never change, and thus the major version skipped from "1" to "13". A new third version number was added to represent changes made by user sites.〔(【引用サイトリンク】title=NEWS.1-17 )〕 In the current numbering scheme, a number with two components signifies a release version, with development versions having three components.〔(【引用サイトリンク】title=GNU Emacs FAQ )〕 GNU Emacs was later ported to Unix. It offered more features than Gosling Emacs, in particular a full-featured Lisp as its extension language, and soon replaced Gosling Emacs as the ''de facto'' Unix Emacs editor. Markus Hess exploited a security flaw in GNU Emacs' email subsystem in his 1986 cracking spree. in which he gained superuser access to Unix computers. Although users commonly submitted patches and Elisp code to the net.emacs newsgroup, GNU Emacs development wasn't relatively open until 1999, and was used as an example of the "Cathedral" development style in ''The Cathedral and the Bazaar''. The project has since adopted a public development mailing list and anonymous CVS access. Development took place in a single CVS trunk until 2008, and today uses the Git〔(【引用サイトリンク】title=Re: GNU EMACS )]〕 DVCS. Richard Stallman has remained the principal maintainer of GNU Emacs, but he has stepped back from the role at times. Stefan Monnier and Chong Yidong have overseen maintenance since 2008.〔(【引用サイトリンク】title=Re: Looking for a new Emacs maintainer or team ); see also ("Stallman on handing over GNU Emacs, its future and the importance of nomenclature" )〕 On September 21 2015 Monnier announced that he would be stepping down as maintainer effective with the feature freeze of Emacs 25.〔https://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00849.html〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「GNU Emacs」の詳細全文を読む スポンサード リンク
