The first widely distributed version of GNU Emacs was 15.34, which appeared in 1985. Stallman’s EmacsLisp derived directly from MacLisp, thus featured several improvements over MockLisp, and had new features specifically suited to editing text and source code. Like with Gosling Emacs, GNU Emacs’s core (user interface and Lisp engine) was written in C, while the engine’s Lisp itself was used to write most parts of the editor’s functionality and is used as integral extension language at the same time. See WikiPedia : GNU Emacs for an extensive history and description. In 1984, Stallman began writing another Emacs implementation based on the former co-planning with Gosling, naming it GnuEmacs, which became the first program in the nascent GNU project. He also gave a speech on his experiences, My Lisp Experiences and the Development of GNU Emacs,, at the International Lisp Conference. The title of the report was EmacsTheExtensibleCustomizableSelfDocumentingDisplayEditor. In 1981, Stallman wrote a report on Emacs as an internal document of the MIT AI Lab. For more info, see WikiPedia : Gosling Emacs). Mock Lisp looked a bit like Lisp, but it was not really Lisp: it lacked true lists (it couldn’t ‘cons’), and handling of function arguments was done in an error-prone, artificial way. It was written in C, with MockLisp at the core of its functionality and as its extension language.
#Emacs copy portable
Gosling Emacs, the first Emacs to run on Unix, was written by JamesGosling in 1981, based on the plans he and RichardStallman had developed for a new, widely portable Emacs. The choice of Lisp provided more extensibility than ever before, and has been followed by most subsequent Emacsen.
User-supplied extensions were also written in Lisp. The editor was written in MacLisp, a dialect of the LISP programming language. In 1978, Bernard Greenberg wrote MulticsEmacs at Honeywell’s Cambridge Information Systems Lab. Ted Anderson wrote SINE (“SINE is not EINE”) for the MagicSix operating system. Several Emacs-like editors were written in the following years, such as EINE ( EINE Is Not EMACS) and ZWEI ( ZWEI Was EINE Initially), written by Daniel Weinreb and Mike McMahon. The title of the report was AnIntroductionToTheEmacsEditor. In January 1978, EugeneCiccarelli wrote an internal document for the MIT AI Lab, introducing the features of Emacs to users. TecoEmacs soon became the standard editor on ITS. In 1976, Stallman wrote the first Emacs (“Editor MACroS”), which organized these macros into a single command set and added facilities for SelfDocumentation and to be extensible. The users at the AI Lab Large soon accumulated a collection of custom macros, TECO programs that could be launched from within the display editing mode.
In 1974, RichardStallman added macro features to the TECO editor. Beginning in 1972, staff hacker CarlMikkelsen added display-editing capability to TECO, the text editor on the AI Lab’s IncompatibleTimeSharingSystem (ITS) “Display-editing” meant that the screen display was updated as the user entered new commands compare the behavior of ed. – George Santayana, Life of Reason, Reason in Common Sense, Scribner’s, 1905, page 284.Įmacs began at the Artificial Intelligence Laboratory at MIT (See MeatBall : MitAiLab). Those who cannot remember the past are condemned to repeat it.
