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. -

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goes far beyond what any Git GUI provides and it takes care of automatically refreshing this output when it becomes outdated.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. -

Tomorrow Theme
Tomorrow Theme
Tomorrow Theme is a family of carefully balanced color schemes designed to provide consistent, readable syntax highlighting across editors, terminals, and code-hosting sites. The palette comes in multiple variants—Tomorrow (light) and several “Tomorrow Night” options like Bright, Blue, and Eighties—so developers can choose a tone that matches their environment without losing legibility. Each scheme defines a small, harmonious set of base and accent colors that map predictably to tokens such as keywords, strings, numbers, and comments, reducing visual noise while preserving structure. The project ships ports for a wide range of tools (from Vim and Emacs to Sublime Text, iTerm, and more) and documents the palette so others can create faithful ports. Its emphasis on restraint and consistency makes it a popular baseline for teams that want code to look familiar across machines and applications. -

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. -

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. -

Clojure Mode
Emacs support for the Clojure(Script) programming language
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) .
