Open Source Emacs-Lisp Text Editors

Mozc is an open source Japanese Input Method Editor (IME) developed by Google, designed to provide Japanese text input across multiple operating systems including Android, macOS, Windows, GNU/Linux, and Chromium OS. The project originated as a subset of Google Japanese Input, released publicly under the BSD 3-Clause license for community use and development. Mozc offers core IME functionality such as text conversion, prediction, and dictionary-based input, enabling users to efficiently type and edit Japanese text. While Mozc shares much of its codebase with Google’s internal IME, it operates as an independent open source project without official support, guarantees, or stable release cycles. Developers can build Mozc from source for their preferred platform, and the repository includes detailed build instructions for Android, Linux, macOS, and Windows environments.

SLIME is a Emacs mode for Common Lisp development. Inspired by existing systems such Emacs Lisp and ILISP, we are working to create an environment for hacking Common Lisp in. SLIME extends Emacs with support for interactive programming in Common Lisp. The features are centered around slime mode, an Emacs minor mode that complements the standard lisp mode. While lisp-mode supports editing Lisp source files, slime-mode adds support for interacting with a running Common Lisp process for compilation, debugging, documentation lookup, and so on. The Read-Eval-Print Loop ("top-level") is written in Emacs Lisp for tighter integration with Emacs. The REPL also has builtin "shortcut" commands similar to those of the McCLIM listener. SLIME is able to take compiler messages and annotate them directly into source buffers.

telega is a full-featured unofficial client for Telegram platform for GNU Emacs. telega is actively developed, for this reason, some features are not implemented, or they are present just as skeletons for future implementation. However, the core parts are mature enough so that it is possible to use telega on daily basis. telega depends on the visual-fill-column and rainbow-identifiers packages. This dependency automatically installs if you install telega from MELPA or GNU Guix. Otherwise, will you need to install these packages by hand? telega is built on top of the official library provided by Telegram TDLib. Most distributions do not provide this package in their repositories, in which case you will have to install it manually by following the instructions. GNU Guix, however, does have both telega and TDLib packaged. If you use GNU Guix you can skip directly to Installing from GNU Guix.

A GNU Emacs binary distribution for users who want to use Emacs natively in 64-Bit Windows (x86_64). This project will focus on providing unmodified, up-to-date (from git master and newest release), and optimized w64 binary builds. Also available on GitHub: https://github.com/zklhp/emacs-w64/releases For details concerning the build, please see the wiki page on https://sourceforge.net/p/emacsbinw64/wiki/Build%20guideline%20for%20MSYS2-MinGW-w64%20system/. 中文版请看这里： http://chriszheng.science/2015/03/19/Chinese-version-of-Emacs-building-guideline/.

This is an Emacs distribution that aims to enhance the default Emacs experience. It alters a lot of the default settings, bundles a plethora of additional packages and adds its own core library to the mix. The final product offers an easy to use Emacs configuration for Emacs newcomers and lots of additional power for Emacs power users. It’s able to run on Windows, GNU Linux and macOS. It is compatible ONLY with GNU Emacs 26.1 and above. In general you’re advised to always run with the latest stable release, currently 28.2. Supports multiple programming languages, C/C++/Object-C/C#/Java, Python/Ruby/Perl/PHP/Shell/Powershell/Bat, JavaScript/Typescript/JSON/YAML, HTML/CSS/XML, and Golang/Swift/Rust/Dart/Elixir.

This project provides clean, optimized w64 binary builds of the latest Emacs git snapshots with image support enabled. It is, however, not *the* official distribution of Emacs. Happy hacking!

RefDB is a reference database and bibliography tool for SGML, XML, and LaTeX documents, sort of a Reference Manager or BibTeX for markup languages. It is portable and known to run on Linux, Free/NetBSD, OSX, Solaris, and Windows/Cygwin.

a jabber (instant messaging) client running atop emacs.

This is an Emacs/XEmacs major mode for editing OmniMark programs. It supports syntax highlighting, and uses heuristics to help with indentation. Additionally, programs can be navigated according to their structure.

Aquamacs Emacs is a Mac-native distribution of the powerful Emacs text editor (versions 23+), featuring Plug&Play and a great UI. Aquamacs feels just right on the Mac, interacts well with other apps, while supporting Emacs' keys and Elisp packages.

Bone Yard is a simple method for inserting default, mode specific, text into empty Emacs buffers. It's used to easily load boilerplate text to get started with new programs.

The Breadcrumb package is an Emacs add-on module that allows setting a series of quick bookmarks in Emacs. The bookmarks are global across different editing buffers, leaving a trail of breadcrumbs across them that you can jump back to quickly.

CC Mode is a GNU Emacs and XEmacs mode for editing C and other languages with similar syntax; currently C++, Objective-C, Java, CORBAs IDL, Pike, and AWK. It is a standard package in both GNU Emacs and XEmacs.

clojure-mode is an Emacs major mode that provides font-lock (syntax highlighting), indentation, navigation and refactoring support for the Clojure(Script) programming language. MELPA Stable is the recommended repo as it has the latest stable version. MELPA has a development snapshot for users who don't mind (infrequent) breakage but don't want to run from a git checkout. Available on the major package.el community maintained repos, MELPA Stable and MELPA repos. All the major modes derive from clojure-mode and provide more or less the same functionality. Differences can be found mostly in the font-locking - e.g. ClojureScript has some built-in constructs that are not present in Clojure. The proper major mode is selected automatically based on the extension of the file you're editing. Having separate major modes gives you the flexibility to attach different hooks to them and to alter their behavior individually (e.g. add extra font-locking just to clojurescript-mode) .

DictEm is an extremely customizable Dictionary client for (X)Emacs. It implements functions of the client part of the Dictionary protocol (RFC-2229). It widely uses autocompletion and provides powerful API that allows to heavily extend its functionality.

tree-sitter is an Emacs binding for Tree-sitter, an incremental parsing system. It aims to be the foundation for a new breed of Emacs packages that understand code structurally. Faster, fine-grained code highlighting. More flexible code folding. Structural editing (like Paredit, or even better) for non-Lisp code. More informative indexing for imenu. The author of Tree-sitter articulated its merits a lot better in this Strange Loop talk. The minor mode tree-sitter-mode provides a buffer-local syntax tree, which is kept up-to-date with changes to the buffer’s text. Run M-x tree-sitter-hl-mode to replace the regex-based highlighting provided by font-lock-mode with tree-based syntax highlighting.

Emacs Lisp libraries for GNU Emacs or XEmacs.

Easymacs is an easy-to-learn, one-size-fits-all configuration for new users of GNU Emacs.

An extensible emacs startup screen showing you what’s most important. The widget “projects”, which shows a list of recent projects, is not enabled by default since it depends on packages that might not be available. To activate the widget, set the variable dashboard-projects-backend to either =’projectile= (projectile, available from melpa) or =’project-el= (project.el, available from GNU elpa), then add an entry like (projects . 5) to the variable dashboard-items. The agenda is now sorted with dashboard-agenda-sort-strategy following the idea of org-agenda-sorting-strategy. Supported strategies are priority-up, priority-down, ~time-up, time-down, todo-state-up and todo-state-down.

markdown-mode is a major mode for editing Markdown-formatted text. The latest stable version is markdown-mode 2.5, released on Feb 12, 2022. See the release notes for details. markdown-mode is free software, licensed under the GNU GPL, version 3 or later. The primary documentation for Markdown Mode is available below, and is generated from comments in the source code. For a more in-depth treatment, the Guide to Markdown Mode for Emacs covers Markdown syntax, advanced movement and editing in Emacs, extensions, configuration examples, tips and tricks, and a survey of other packages that work with Markdown Mode. Finally, Emacs is also a self-documenting editor. This means that the source code itself contains additional documentation: each function has its own docstring available via C-h f (describe-function), individual keybindings can be investigated with C-h k (describe-key), and a complete list of keybindings is available using C-h m (describe-mode).
