Mozc
Mozc - a Japanese Input Method Editor designed for multi-platform
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. -

GNU Emacs / N Λ N O
Emacs made simple
GNU Emacs / N Λ N O is a lightweight, minimalistic Emacs-inspired text editor configuration (or “distribution”) created by Nicolas P. Rougier that aims to provide a simpler and more streamlined experience compared to full-blown Emacs setups. It retains essential editing capabilities while stripping down much of the complexity and heavyweight features that can make traditional Emacs intimidating to newcomers. The project includes only minimal configuration and essential extensions, enabling users to start editing text comfortably without wrestling with a steep learning curve or bloated init files. This makes it appealing for users who like the power of Emacs (or similar advanced editors) but want a fast, responsive, and easy-to-maintain editor. Nano-Emacs can be especially useful for scripting, quick edits, data-analysis workflows, or writing in scientific/research contexts, especially when you want something more powerful than a simple text editor but lighter than a full IDE. -

telega.el
GNU Emacs telegram client (unofficial)
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. -

zenburn-theme for Emacs
The Zenburn colour theme ported to Emacs
Zenburn for Emacs is a direct port of the popular Zenburn theme for vim, developed by Jani Nurminen. It's my personal belief (and that of its many users I presume) that it's one of the best low-contrast color themes out there and that it is exceptionally easy on the eyes. This theme uses the "new" (it used to be new several years ago when I created this package) built-in theming support available starting with Emacs 24.1. You can support the development of Zenburn for Emacs via GitHub Sponsors, ko-fi, PayPal and Patreon. Zenburn for Emacs is already bundled into Emacs Prelude. If you're a Prelude user - you're probably already using Zenburn, since it's Prelude's default color theme. You can load Zenburn at any time by M-x load-theme zenburn. If you'd like to tweak the theme by changing just a few colors, you can do so by defining new values in the zenburn-override-colors-alist variable before loading the theme. -

Irony-Mode
A C/C++ minor mode for Emacs powered by libclang
irony-mode is an Emacs minor-mode that aims at improving the editing experience for the C, C++ and Objective-C languages. It works by using a combination of an Emacs package and a C++ program (irony-server) exposing libclang. irony-server provides the libclang interface to irony-mode. It uses a simple protocol based on S-expression. This server, written in C++ and requires the specified packages to be installed on your system. Exactly one package manager should manage irony-mode. If using apt, but the MELPA package is desired, uninstall the version managed by apt; Likewise, installing from both MELPA and straight.el may result in a state that requires a manual workaround. The backports mechanism is the recommended and officially supported method of accessing newer versions than Debian stable provides. In order to work correctly, irony-mode needs to know the compile flags. irony-cdb aims to provide as automatic as possible compile flags discovery, with minimal user input. -

Magit
A Git porcelain inside Emacs
Magit is a complete text-based user interface to Git. It fills the glaring gap between the Git command-line interface and various GUIs, letting you perform trivial as well as elaborate version control tasks with just a couple of mnemonic key presses. Magit looks like a prettified version of what you get after running a few Git commands but in Magit every bit of visible information is also actionable to an extent that goes far beyond what any Git GUI provides and it takes care of automatically refreshing this output when it becomes outdated. In the background Magit just runs Git commands and if you wish you can see what exactly is being run, making it possible for you to learn the git command-line by using Magit. Using Magit for a while will make you a more effective version control user. Magit supports and streamlines the use of Git features that most users and developers of other Git clients apparently thought could not be reasonably mapped to a non-command-line interface. -

SLIME
The Superior Lisp Interaction Mode for Emacs
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. -

CIDER
The Clojure Interactive Development Environment that Rocks for Emacs
CIDER extends Emacs with support for interactive programming in Clojure. The features are centered around cider-mode, an Emacs minor-mode that complements clojure-mode. While clojure-mode supports editing Clojure source files, cider-mode adds support for interacting with a running Clojure process for compilation, debugging, definition and documentation lookup, running tests, and so on. CIDER aims to provide an interactive development experience similar to the one you’d get when programming in Emacs Lisp, Common Lisp (with SLIME or Sly), Scheme (with Geiser), and Smalltalk. Programmers are expected to program in a very dynamic and incremental manner, constantly re-evaluating existing Clojure definitions and adding new ones to their running applications. You never stop/start a Clojure application while using CIDER - you’re constantly interacting with it and changing it. -

Casual Suite
An umbrella package to support a single install point
An umbrella package to support a single installation point for all Casual user interfaces for Emacs. These user interfaces built with Transient are included via the Elisp library header Package-Requires. It is highly recommended that a deep reading of the install procedure for each user interface be done beforehand as each of them has their own recommended customizations to go alongside them. Casual Suite requires Casual Lib which in turn requires a recent installation of Transient 0.6.0+ from either ELPA or MELPA. As an older version of Transient is built-in to the Emacs release, the package manager package.el will not update this package unless the customizable variable package-install-upgrade-built-in is set to t. Set this variable and proceed with installing Casual Suite. Alternately invoking package-install with a prefix (C-u) will temporarily coerce the update of the built-in package. -
