tracking.el provides a way for different modes to notify the user that a buffer needs attention. The user then can cycle through them using C-c C-SPC.

This package allows you to execute org-mode source code blocks with eval-in-repl. It can execute code blocks asynchronously, without needing to write the result into the buffer.

This package adds new RSS generation options to the org-publish-project-alist variable (see the Org manual if you are new to the publishing options). It adds :auto-rss and other options that work similar to the included :auto-sitemap functionality. This should make it easy for users to add RSS feeds to existing Org-based websites.

This package provides a development environment and REPL interaction package for Julia in the spirit of Common Lisp’s SLIME and Clojure’s CIDER. It enables convenient and dynamic REPL-driven development.

This package provides an optional extension to denote for naming files with a sequencing scheme. The idea is to establish hiearchical relationships between files, such that the contents of one logically follow or complement those of another.

This package provides a frontend for Flycheck that lets irony-mode do the syntax checking.

This package provides an Emacs based interface for GNU Go, which can be started via M-x gnugo. It has a graphical mode where the board and stones are drawn using XPM images and supports the use of a mouse. You can switch to the graphical mode by running M-x gnugo-image-display-mode.

This package provides an Emacs major mode which acts as a front end to mpc, a client for the Music Player Daemon (MPD).

This package allows reading Reddit from within Emacs interactively.

Nyan mode is an analog indicator of your position in the buffer. The cat should go from left to right in your mode-line, as you move your point from 0% to 100%. You can click on the rainbow or the empty space to scroll backwards and forwards and also animate it.

elisp-def finds Emacs Lisp symbol definitions intelligently. It understands namespaces, macros, libraries and local bindings.

This package provides syntax highlighting, a minor mode for listing type errors via Flycheck, as well as REPL support for Carp.

This package provides an Emacs major mode for editing Arduino sketches and Org Babel support.

ob-async enables asynchronous execution of org-babel src blocks.

E2WM is a window manager for Emacs. It enables to customize the place of pop-up window, how the windows are split, how the buffers are located in the windows, keybinds to manipulate windows and buffers, etc. It also has plug-ins to help your Emacs life.

emacs-evil-surround allows easy deletion, change and addition of surrounding pairs, such as parentheses and quotes, in evil mode.

Due to the structure of Lisp syntax it's very rare for the programmer to want to insert characters right before "(" or right after ")". Thus unprefixed printable characters can be used to call commands when the point is at one of these special locations. Lispy provides unprefixed keybindings for S-expression editing when point is at the beginning or end of an S-expression.

This Emacs package provides modes for ebuild, eclass, eblit, GLEP42 news items, openrc and runscripts.

Dracula is a dark color theme for many editors, shells and more. This package provides the Emacs theme.

This package extends lsp-mode to work with C and C++ files through the ccls language server.

This program sends HTML email using Org-mode HTML export. This approximates a WYSiWYG HTML mail editor from within Emacs, and can be useful for sending tables, fontified source code, and inline images in email.

This package provides project templates and automates the mundane parts of setting up a new project, such as version control, licenses, and tooling.

This package provides an ESS-like binding to send lines or regions to a REPL from Clojure buffers.

Selectrum is a solution for incremental narrowing in Emacs, replacing Helm, Ivy, and IDO. Its design philosophy is based on choosing the right abstractions and prioritizing consistency and predictability over special-cased improvements for particular cases. As such, Selectrum follows existing Emacs conventions where they exist and are reasonable, and it declines to implement features which have marginal benefit compared to the additional complexity of a new interface.
