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goes far beyond what any Git GUI provides and it takes care of automatically refreshing this output when it becomes outdated.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

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. -

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. -

lispy
Short and sweet LISP editing
This package reimagines Paredit - a popular method to navigate and edit LISP code in Emacs. Most of more than 100 interactive commands that lispy provides are bound to a-z and A-Z in lispy-mode. The advantage of short bindings is that you are more likely to use them. As you use them more, you learn how to combine them, increasing your editing efficiency. To further facilitate building complex commands from smaller commands, lispy-mode binds digit-argument to 0-9. For example, you can mark the third element of the list with 3m. You can then mark third through fifth element (three total) with 2> or >>. You can then move the selection to the last three elements of the list with 99j. If you are currently using Paredit, note that lispy-mode and paredit-mode can actually coexist with very few conflicts, although there would be some redundancy. -

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. -

Lux
The Lux Programming Language
Lux is a new programming language in the making. It's meant to be a functional, statically-typed Lisp that will run on several platforms, such as the Java Virtual Machine and JavaScript, Python, Lua, or Ruby interpreters. Lux is in the beta stage. The JVM compiler is pretty stable and the standard library has grown to a respectable size. Also, new experimental support for JavaScript, Python, Lua, and Ruby has been added. Read carefully before using this project, as the license disallows commercial use, and has other conditions which may be undesirable for some. The language is mostly inspired by the following 3 languages. Clojure (syntax, overall look & feel), Haskell (functional programming), and Standard ML (module system). They are implemented as plain-old data-structures whose expressions get eval'ed by the compiler and integrated into the type-checker. The main difference between Lux & Standard ML is that Standard ML separates interfaces/signatures and implementations/structures. -

org-roam-server
A web application to visualize the Org-Roam database
A web application to visualize the Org-Roam database. For org-roam v2, use org-roam-ui, org-roam-server only works with org-roam v1. Use M-x org-roam-server-mode RET to enable the global mode. It will start a web server. Although it will automatically reload if there is a change in the database, sometimes it fails to establish a connection. If it does not reload after org-roam-build-cache, you can do it manually by clicking the reload button which will reload the data, rebuild the graph and refresh connections. The graph utilizes org-roam protocol which means if you click on one of the nodes, it will open the corresponding file in Emacs. For this feature to work, org-roam protocol should be configured in the system. -

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. -
