GccEmacs refers to the --with-native-compilation configuration option when building Emacs, which adds support for compiling EmacsLisp to native code using libgccjit. All of the Elisp packages shipped with Emacs are native-compiled, providing a noticeable performance improvement out-of-the-box. Third-party packages are also compiled to achieve further performance improvements. The official developm
Emacs for ChromeBooksEmacs can be run on a ChromeBook by using the Linux system for Chromebooks. Once upon a time in 2015, Chrome had a development environment called NaCl (Native Client). It could run many GNU/Linux utilities, implemented a virtual file system, and had an Emacs port to NaCl so you could do software development with Emacs on a ChromeBook (and in fact on any browser that supported
This page is about Omit Mode in Dired, which lets you hide uninteresting files, such as backup files and AutoSave files. ‘C-x M-o’ in Dired buffers toggles this mode. To enable omitting in every Dired buffer, you can use: (add-hook 'dired-mode-hook (lambda () (dired-omit-mode)))Variables ‘dired-omit-files’ and ‘dired-omit-extensions’ together define the uninteresting files.

For the former contents of this page which were for a large part concerned with the history of all efforts to integrate Guile and Emacs, see GuileEmacsHistory. To try Guile Emacs in its current state, see GuileEmacsBuild. OverviewGuile-based Emacs is a branch of GNU Emacs that replaces Emacs’s own EmacsLisp engine with the Elisp compiler of Guile. It does not attempt to remove Elisp, and instead a
Git quick start guide for Emacs DevelopersEmacs uses Git as its version control system.

The “workflow” described in this document allows you to: Contribute to Emacs in a CVS-like way, including the us

The variable ‘compile-command’ holds the default value for the `M-x compile’ command. The default value is “make -k” which is good enough for most projects, because you’ll either have a Makefile, or you can rely on the default rules within make. And if you change the default, Emacs will remember that. However, some people might still want to experiment with it. Take a look at the compile-command d
Here’s the normal way of adding new keywords to a mode. Let us start with the simplest example: (font-lock-add-keywords 'emacs-lisp-mode '(("foo" . font-lock-keyword-face))) It makes “foo” a keyword in EmacsLisp mode. More ExamplesHere is a simple example from the documentation of font-lock-add-keywords: (font-lock-add-keywords 'c-mode '(("\\<\\(FIXME\\):" 1 font-lock-warning-face prepend) ("\\<\\

See also: LocalVariables, FileLocalVariables From the manual, Directory Variables If you put a file with a special name .dir-locals.el in a directory, Emacs will read it when it visits any file in that directory or any of its subdirectories, and apply the settings it specifies to the file’s buffer. Emacs searches for `.dir-locals.el’ starting in the directory of the visited file, and moving up the
Eww (the Emacs Web Wowser) is a Web browser written in elisp and based on shr.el. Eww is included in Emacs 24.4 and later.

Node-JS is a Javascript runtime enviroment, popular for making async web and TCP servers. There are several modes for running node.js inside of Emacs: Using comint modeThe simplest method is to just use Emacs’s Comint mode: (defun node-repl () (interactive) (setenv "NODE_NO_READLINE" "1") ;avoid fancy terminal codes (pop-to-buffer (make-comint "node-repl" "node" nil "--interactive"))) (node-repl)U
This page is about commenting parts of code. Each code language has its own comment string for commenting-out code. In Emacs lisp, for example, it is ;. Some languages have different comment strings for comment start and end. These are the values of mode-specific variables comment-start and comment-end. For example, in C, comment-start is /* and comment-end is */. The main command for commenting o
AbstractA project to make Emacs more frame-oriented is introduced. Discussion of the problem and suggestions of solutions are invited. An existing implementation is described. Problem: Emacs Is Biased Toward Windows, Not FramesSeveral major versions ago, Emacs introduced frames, which correspond to window-manager windows. A frame is tiled into one or more panes – we call them windows in Emacs-spea
You can specify frame size and position at any time, including at Emacs startup and interactively, incrementally. At Emacs StartupPossibilities: Use command line options-mm: Maximize the first frame. E.g, use this as the Target of an MS Windows shortcut: runemacs -mm.-geometry: Set the first frame’s dimensions. E.g., emacs -geometry 80x24 for a frame 80 chars wide and 24 chars high.Use file ~/.Xre
This is about indenting with tabs and aligning with spaces. For Sébastien Rocca-Serra’s smart-tab command, see TabCompletion.Tabs and spaces are often misunderstood. (Original comic by Steve Napierski.)There is a semantic way of using tab characters in source code: tabs for indentation, spaces for alignment. This ensures that the code is displayed correctly everywhere, regardless of the viewer’s t
ELPA is the Emacs Lisp Package Archive, written originally by TomTromey. It is included in GnuEmacs, starting with version 24. package.el is the package manager library for ELPA. “Our goal is to make it simple to install, use, and upgrade Emacs Lisp packages. We supply package.el a simple package manager for Emacs, and a repository of pre-packed Emacs Lisp code.” See InstallingPackages for basic u
Native Smooth ScrollingThe next release of Emacs, Emacs 29, will come with built-in support for pixel-based scrolling. You can enable it using ‘pixel-scroll-precision-mode’. You will need to build with XInput 2 support (which should be on by default, but may require libXi to be installed), unless you’re not using X. If you want Emacs to continue to “drift” the display after it stops, and you aren’

This page is about executing Lisp code to get the replacement string in ‘replace-regexp’ and ‘query-replace-regexp’ commands. This feature is available starting with Emacs version 22. For earlier versions of Emacs, use instead the ‘query-replace-regexp-eval’ command; see ReplaceCount for some examples. Capitalize words M-x replace-regexp Replace regexp: \(\w+\) Replace regexp with: \,(capitalize \

The Simple Solution: Counting Words on Demand1. Select a region. 2. Run M-=, or M-| wc for older versions of emacs. 3. See the count of lines, words, and characters, in the mode-line. Show the number of words in the mode-lineThe minor mode ‘word-count-mode’ displays the number of words in the current buffer. It is quite handy: http://taiyaki.org/elisp/word-count/src/word-count.el (down on Nov. 1,
