Polymode is an Emacs package that offers generic support for multiple major modes inside a single Emacs buffer. It is lightweight, object oriented and highly extensible. Creating a new polymode typically takes only a few lines of code. Polymode also provides extensible facilities for external literate programming tools for exporting, weaving and tangling.

ob-gptel is a backend for Org Babel. It provides an alternative interface to evaluate {gptel

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

Extension for mu4e or gnus to colorize patch-like emails with diff-mode. This is based on Frank Terbeck's gnus-article-treat-patch.el but has been adapted to also work with mu4e.

This package provides an introspection tool similar to those found in Common Lisp or Smalltalk, but for Emacs Lisp.

This package provides a set of Emacs themes that conform with a minimalist aesthetic: they use few colours and appear monochromatic in many contexts

danneskjold-theme is a high-contrast theme for Emacs.

Mocker.el is a framework for writing tests in Emacs Lisp. It uses regular Lisp rather than a domain specific language (DSL), which maximizes flexibility (at the expense of conciseness).

Literate-Elisp is an Emacs lisp library to provide an easy way to use literal programming in Emacs lisp. It extends the Emacs load mechanism so Emacs can load Org files as Lisp source files directly.

EBDB-i18n-Chn makes EBDB nicer to use with China-based contacts, both for handling Chinese characters, and for formatting of phones and addresses. Be aware that using this library will incur a non-neglible slowdown at load time. It shouldn't have any real impact on search and completion times.

This mode pastes whole buffers or parts of buffers to pastebin-like services. It supports more than one service and will failover if one service fails. More services can easily be added over time and preferred services can easily be configured.

This Emacs package provides the commands aa2u and aa2u-rectangle. Both of these commands can be used to convert simple ASCII art line drawings to Unicode; the former works on the active region of the buffer, while the latter works on rectangular selections.

This projects aims to become an aesthetic, functional and efficient tabs plugin for Emacs with a lot of customization options.

This package provides a minor mode for renaming buffers according to project structure. For Python buffers, that will be the whole module name. For temporary files and directories, that will be the relative path from the project root.

Eyebrowse is a global minor mode for Emacs that allows you to manage your window configurations in a simple manner, just like tiling window managers like i3wm with their workspaces do. It displays their current state in the modeline by default.

This package provides a function to list all current major mode's parent modes.

This package provides an Adwaita-inspired dark color scheme for Emacs.

A bleak theme. Uses shades of gray and the occasional splash of color. Designed for 256-color terminals. Comes in light and dark!

This package provides a Company backend for Python.

Drag Stuff is a minor mode for Emacs that makes it possible to drag stuff (words, region, lines) around in Emacs.

Interleave is a minor mode that presents a document viewer side by side to an Org buffer with your notes relevant to the current page.

Helm "Switch-to-REPL" offers the helm-switch-to-repl action, a generalized and extensible version of helm-ff-switch-to-shell. It can be added to helm-find-files and other helm-type-file sources such as helm-locate.

This package provides an edit server to respond to requests from Emacs.

This integrates Flycheck with Helm.
