gnu-emacs@gentoo.org Gentoo GNU Emacs project GNU Emacs is an extensible, customizable text editor - and more. At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing. The features of GNU Emacs include: * Content-sensitive editing modes, including syntax coloring, for a variety of file types including plain text, source code, and HTML. * Complete built-in documentation, including a tutorial for new users. * Full Unicode support for nearly all human languages and their scripts. * Highly customizable, using Emacs Lisp code or a graphical interface. * A large number of extensions that add other functionality, including a project planner, mail and news reader, debugger interface, calendar, and more. Many of these extensions are distributed with GNU Emacs; others are available separately. Enable the MIT Athena widget set (x11-libs/libXaw) Enable loading of dynamic libraries (modules) at runtime Support shared score files for games Use gfile (dev-libs/glib) for file notification Use the GNU multiple precision arithmetic library (dev-libs/gmp) instead of the bundled mini-gmp subset Use gsettings (dev-libs/glib) to read the system font name Compress bundled Emacs Lisp source Use media-libs/harfbuzz as text shaping engine Use media-gfx/imagemagick for image processing Compile with Emacs Lisp native compiler support via libgccjit Compile with native JSON support using dev-libs/jansson Use dev-libs/libxml2 to parse XML instead of the internal Lisp implementations Retrieve e-mail using net-mail/mailutils instead of the internal movemail substitute Install C source files and make them available for find-function Add elisp threading support Use the selected toolkit's scrollbars in preference to Emacs' own scrollbars Support the dev-libs/tree-sitter parsing library Prefer wide Emacs integers (typically 62-bit). This option has an effect only on 32-bit systems, where it increases the maximum buffer size from 0.5 to 2 GiB, at the cost of 10% to 30% Lisp slowdown. emacs
