Elpy brings powerful Python editing to Emacs. It combines and configures a number of other packages written in Emacs Lisp as well as Python, together offering features such as navigation, documentation, completion, interactive development and more.

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 a macro that writes your namespaces for you.

jabber.el is an XMPP client for Emacs. XMPP (also known as "Jabber") is an instant messaging system; see https://xmpp.org for more information.

Unfold CSS-selector-like expressions to markup. It is intended to be used with SGML-like languages: XML, HTML, XHTML, XSL, etc.

Column Enforce mode highlights text that extends beyond a certain column. It can be used to enforce 80 column rule. It can also be configured for any N-column rule.

This package allows for keybindings, settings, hooks, and advice to be recorded and displayed.

This Flycheck extension configures Flycheck automatically for the current Cargo project.

This package provides two parameterized uncolored color themes for Emacs: tao-yin and tao-yang. The default tao-theme-scale-fn is tao-theme-golden-scale.

You can customize: tao-theme-scale-fn, that returns 16 2-digit numbers; tao-theme-scale-filter-fn, for edge filter; and tao-theme-use-height.

Debpaste is an Emacs interface for the Debian Pastezone, allowing you to receive, post, and delete pastes. It communicates with the server using XML-RPC.

This package allows for bookmarking eshell buffers. Upon visiting the bookmark, a new eshell session will be opened in the appropriate directory if no eshell session is active.

ace-window is meant to replace other-window. In fact, when there are only two windows present, other-window is called. If there are more, each window will have its first character highlighted. Pressing that character will switch to that window.

This package prettifies headings and plain lists in Org mode. It is a direct descendant of org-bullets, with most of the code base completely rewritten.

Currently, this package prettifies Org heading lines by:

• replacing trailing bullets by UTF-8 bullets,

• hiding leading stars, customizing their look or removing them from vision,

• applying a custom face to the header bullet,

• applying a custom face to the leading bullets,

• using double-bullets for inline tasks,

• (optional) using special bullets for TODO keywords.

It also prettifies Org plain list bullets by:

• replacing each bullet type (*, + and -) with UTF-8 bullets,

• applying a custom face to item bullets.

Features degrade gracefully when viewed from terminal.

Purpose is a package that introduces the concept of a "purpose" for windows and buffers, and then helps you maintain a robust window layout easily.

Roguel-ike is an attempt to develop a coffee-break roguelike for Emacs. The complete game would allow the player to create various characters and to make them fulfill challenges like arena fight and short dungeon explorations.

Vlf is an Emacs minor mode that allows viewing, editing, searching and comparing large files in batches.

This package provides many, but not all of the editing primitives in the Kakoune editor. Unlike Evil mode for Vim, this is a very shallow emulation, which seeks to do as little work as possible, leveraging Emacs native editing commands and the work of other packages wherever possible.

All-the-icons is a utility package to collect various icon fonts and propertize them within Emacs. Icon fonts allow you to propertize and format icons the same way you would normal text. This enables things such as better scaling of and anti aliasing of the icons.

SLY is Sylvester the Cat's Common Lisp IDE. SLY is a fork of SLIME, and contains the following improvements over it:

1. A full-featured REPL based on Emacs's comint.el. Everything can be copied to the REPL;

2. Stickers, or live code annotations that record values as code traverses them.

3. Flex-style completion out-of-the-box, using Emacs's completion API. Company, Helm, and other supported natively, no plugin required;

4. An interactive Trace Dialog;

5. Multiple inspectors and multiple REPLs, with independent history.

6. Regexp-capable M-x sly-apropos.

7. Cleanly ASDF-loaded by default, including contribs, enabled out-of-the-box;

8. "Presentations" replaced by interactive backreferences, which highlight the object and remain stable throughout the REPL session;

SLY tracks SLIME's bugfixes and all its familiar features (debugger, inspector, xref, etc.) are still available, but with better integration.

Gruvbox is heavily inspired by badwolf, jellybeans and solarized.

Designed as a bright theme with pastel 'retro groove' colors and light/dark mode switching in the way of solarized. The main focus when developing gruvbox is to keep colors easily distinguishable, contrast enough and still pleasant for the eyes.

The standard-themes are a pair of light and dark themes for GNU Emacs. They emulate the out-of-the-box looks of Emacs (which technically do not constitute a theme) while bringing to them thematic consistency, customizability, and extensibility.

This package provides functions for converting Unicode to ASCII.

This is a backend implementation for the completion package company-mode which supports the normal and the fuzzy completion modes of SLIME.

Prescient is a library for sorting and filtering, as well as extensions for Ivy and Company that make use of the library.
