For a period of time XEmacs even had some terminal-specific features, such as coloring, that GNU Emacs lacked. The software community generally refers to GNU Emacs, XEmacs (and a number of other similar editors) collectively or individually as emacsen (by analogy with oxen) or as emacs, since they both take their inspiration from the original ...
Spacemacs is a configuration framework for GNU Emacs. [6] It can take advantage of all of GNU Emacs' features, including both graphical and command-line user interfaces, and being executable under X Window System and within a Unix shell terminal. [7] It is free and open-source software (FOSS) released under the GPL-3.0-or-later license. [3] [4] [5]
Richard Stallman, founder of the GNU Project and author of GNU Emacs. The original EMACS was written in 1976 by David A. Moon and Guy L. Steele Jr. as a set of macros for the TECO editor, and in 1984, Richard Stallman began work on GNU Emacs, to produce a free software replacement to the proprietary Gosling Emacs.
Epsilon, [46] an Emacs clone by Lugaru Software. Versions for DOS, Windows, Linux, FreeBSD, Mac OS X and OS/2 are bundled in the release. It uses a non-Lisp extension language with C syntax and used a very early concurrent command shell buffer implementation under the single-tasking MS-DOS. PceEmacs is the Emacs-based editor for SWI-Prolog.
Programming languages that support arbitrary precision computations, either built-in, or in the standard library of the language: Ada: the upcoming Ada 202x revision adds the Ada.Numerics.Big_Numbers.Big_Integers and Ada.Numerics.Big_Numbers.Big_Reals packages to the standard library, providing arbitrary precision integers and real numbers.
It has a compatibility mode with Maple, Derive and MuPAD software and TI-89, TI-92 and Voyage 200 calculators. The system was chosen by Hewlett-Packard as the CAS for their HP Prime calculator, which utilizes the Giac/Xcas 1.1.2 engine under a dual-license scheme.
MicroEMACS is a small, portable Emacs-like text editor originally written by Dave Conroy in 1985, and further developed by Daniel M. Lawrence (1958–2010 [2] [3]) and was maintained by him. MicroEMACS has been ported to many operating systems , including CP/M , [ 4 ] MS-DOS , Microsoft Windows , VMS , Atari ST , AmigaOS , OS-9 , NeXTSTEP , and ...
In Emacs, the editing area can be split into separate areas called windows, each displaying a different buffer. A buffer is a region of text loaded into Emacs' memory (possibly from a file) which can be saved into a text document. Users can press the default C-x 2 key binding to open a new window. This runs the Emacs Lisp function split-window ...
