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. -

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. -

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. -

Spacemacs
A community-driven Emacs distribution
The best editor is neither Emacs nor Vim, it's Emacs *and* Vim, courtesy of Spacemacs! Spacemacs is an extension of the popular text editor Emacs, that offers a whole new way of experiencing Emacs. It is a community-driven Emacs distribution that focuses on ergonomics, mnemonics and consistency. Using it comes naturally to both Emacs and Vim users. In fact, you could even combine the two editing styles. Enabling you to switch between input styles makes Spacemacs a great choice for pair-programming. Spacemacs features a beautiful GUI and exceptional ergonomics, with all the key bindings easily accessible simply by pressing the space bar or alt-m. Spacemacs also comes with hundreds of curated, ready-to-use packages that are well organised in configuration layers. -

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. -

Emacs Dashboard
An extensible emacs dashboard
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. -

dap-mode
Emacs Debug Adapter Protocol
Emacs client/library for Debug Adapter Protocol is a wire protocol for communication between client and Debug Server. It's similar to the LSP but provides integration with debug server. The API considered unstable until 1.0 release is out. It is tested against Java, Python, Ruby, Elixir and LLDB (C/C++/Objective-C/Swift). The main entry points are dap-debug and dap-debug-edit-template. The first one asks for a registered debug template and starts the configuration using the default values for that particular configuration. The latter creates a debug template which could be customized before running. dap-debug-edit-template will prepare a template declaration inside a temporary buffer. You should execute this code using C-M-x for the changes to apply. You should also copy this code into your Emacs configuration if you wish to make it persistent. -

org-ql
An Org-mode query language, including search commands and saved views
This package provides a query language for Org files. It offers two syntax styles: Lisp-like sexps and search engine-like keywords. It includes three libraries: The org-ql library is flexible and may be used as a backend for other tools. The libraries org-ql-search and helm-org-ql (a separate package) provide interactive search commands and saved views. The package org-ql may be installed directly from MELPA or with other tools like Quelpa. After installation, you can use the commands without additional configuration. To use the functions and macros in your own Elisp code, use libraries org-ql and org-ql-view. Feedback on these APIs is welcome. Eventually, after being tested and polished, they will be considered stable. When formatting entries for Org QL View buffers, use internal function for retrieving heading tags. This improves speed by using our cache, and it removes the need for a compatibility alias for Org versions before 9.3. -
