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.

Pinentry provides a console and an Emacs interface that allows users to enter a passphrase when required by gpg or other software.

This package adds a single command dired-rsync which allows the user to copy marked files in a Dired buffer via rsync. This is useful, especially for large files, because the copy happens in the background and doesn’t lock up Emacs. It is also more efficient than using Tramp's own encoding methods for moving data between systems.

This package provides an Emacs interface for performing searches with ripgrep.

GNU Emacs is an extensible and highly customizable text editor. It is based on an Emacs Lisp interpreter with extensions for text editing.

Org is an Emacs mode for keeping notes, maintaining TODO lists, and project planning with a fast and effective lightweight markup language. It also is an authoring system with unique support for literate programming and reproducible research.

This is a major mode for managing password-store (pass) keychains. The keychain entries are displayed in a directory-like structure and can be consulted and modified.

This library provides easy project management and navigation. The concept of a project is pretty basic: just a folder containing special file. Currently Git, Mercurial and Bazaar repositories are considered projects by default. If you want to mark a folder manually as a project just create an empty .projectile file in it.

This package provides commands to open a shell buffer in (or relative to) the default-directory or – using projectile or find-file-in-project – a project root.

Elfeed-protocol provides extra protocols to make self-hosting RSS readers like Fever, NewsBlur, ownCloud News and Tiny TIny RSS work with Elfeed.

This package provides a major mode dockerfile-mode for use with the standard Dockerfile file format.

Vertico provides a minimalistic vertical completion UI, which is based on Emacs' default completion system. By reusing the default system, it achieves full compatibility with built-in Emacs commands and completion tables. Vertico is pretty bare-bone and only provides a minimal set of commands. Additional optional enhancements can be provided externally by complementary packages.

Aids maintenance of Firefox-based packages in Guix by fetching CVEs from Firefox release notes and formatting them for Guix commit message.

With Magit, you can inspect and modify your Git repositories with Emacs. You can review and commit the changes you have made to the tracked files, for example, and you can browse the history of past changes. There is support for cherry picking, reverting, merging, rebasing, and other common Git operations.

Emacspeak is a speech interface that allows visually impaired users to interact independently and efficiently with the computer. Audio formatting---a technique pioneered by AsTeR---and full support for W3C's Aural CSS (ACSS) allows Emacspeak to produce rich aural presentations of electronic information. By seamlessly blending all aspects of the Internet such as Web-surfing and messaging, Emacspeak speech-enables local and remote information via a consistent and well-integrated user interface.

Alert is a Growl-workalike for Emacs which uses a common notification interface and multiple, selectable "styles", whose use is fully customizable by the user.

This package provides a major mode for editing Fluke 9010a "9LC" files.

EMMS is the Emacs Multimedia System. It is a small front-end which can control one of the supported external players. Thus, it supports whatever formats are supported by your music player. It also supports tagging and playlist management, all behind a clean and light user interface.
