Rudel is a collaborative editing environment for GNU Emacs. Its purpose is to share buffers with other users in order to edit the contents of those buffers collaboratively. Rudel supports multiple backends to enable communication with other collaborative editors using different protocols, though currently Obby (for use with the Gobby editor) is the only fully-functional one.

This program is derived from comint-mode and provides the following features:

• TAB completion same as Node.js REPL

• file name completion in string

• incremental history search

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

This package provides enhancements to standard Font Lock library.

m-buffer provides a set of list-orientated functions for operating over the contents of Emacs buffers.

emacs-org-pomodoro adds very basic support for Pomodoro technique in Emacs org-mode.

Run M-x org-pomodoro for the task at point or select one of the last tasks that you clocked time for. Each clocked-in pomodoro starts a timer of 25 minutes and after each pomodoro a break timer of 5 minutes is started automatically. Every 4 breaks a long break is started with 20 minutes. All values are customizable.

Spaceline provides Spacemacs' mode-line theme. This package provides features for three kinds of users.

• You just want to use the Spacemacs mode-line theme and forget about it.

• You want to use something similar to the Spacemacs mode-line theme, but with a handful of easy tweaks.

• You want an easy-to-use library for building your own mode-line from scratch, and you think the Spacemacs theme looks good.

Shell-command+ is a shell-command substitute that extends the regular Emacs command with several features. You can for example count all the lines in a buffer with > wc -l, or delete all lower case letters in the selected region with | tr -d a-z.

Emacs Polyglot, or Eglot, is an Emacs Language Server Protocol client that stays out of the way. It guesses the LSP program to start for the current file, using the major mode as a hint. It prompts you to enter one if it fails.

There are some great packages for exporting buffers to particular formats, but each one seems to reinvent the core mechanism of processing the font-lock in a buffer such that it can be exported to a particular format.

This package aims to produce a versatile generic core which can process a fontified buffer and pass the data to any number of backends which can deal with specific output formats.

This package provides an Emacs functions to format HTML, CSS, JavaScript, JSON.

This Emacs package allows you to show M-x speedbar in the same frame (in an extra window). You can customize the initial width of the speedbar window.

The Bug Hunter is an Emacs library that finds the source of an error or unexpected behavior inside an elisp configuration file (typically init.el or .emacs).

ultra-scroll is a smooth-scrolling package for Emacs. It provides highly optimized, pixel-precise smooth-scrolling which can readily keep up with the very high event rates of modern track-pads and high-precision wheel mice.

This package uses Ivy to provide additional actions for Projectile commands and replacements for existing functions.

Org Reveal exports your Org documents to reveal.js presentations. With org-reveal, you can create beautiful presentations with 3D effects from simple but powerful Org contents.

message-x assigns a context-sensitive function to the TAB key in Message mode. When on a header line, it performs completion based on which header we are in (for example, newsgroup name completion makes sense on the Newsgroups header, whereas mail alias expansion makes sense in the To and Cc headers). When in the message body, this executes a different function (default: indent-relative).

This package allows GnuPG passphrase to be prompted through the minibuffer instead of graphical dialog.

To use, add allow-emacs-pinentry to ~/.gnupg/gpg-agent.conf, reload the configuration with gpgconf --reload gpg-agent, and start the server with M-x pinentry-start.

This package adds support for the Racket implementation to Geiser, a generic Scheme interaction mode for the GNU Emacs editor.

Parseclj is an Emacs Lisp library for parsing Clojure code and EDN data. It supports several input and output formats, all powered by the same shift-reduce parser function.

GN mode is a major mode for editing GN config files in Emacs. Files of this type (e.g., BUILD.gn or *.gni) are common in Chromium-derived projects.

Jarchive makes Emacs handle Java and LSP URIs pointing to source inside JARs.

Gnosis is a spaced repetition system for note-taking and self-testing where notes are formatted as Question/Answer/Explanation. Notes are reviewed at spaced intervals based on the success or failure in recalling the answer to each question.

Org Books is a tool for managing reading lists in an Org mode file.
