pcre2el or rxt (RegeXp Translator or RegeXp Tools) is a utility for working with regular expressions in Emacs, based on a recursive-descent parser for regexp syntax. In addition to converting (a subset of) PCRE syntax into its Emacs equivalent, it can do the following:

• convert Emacs syntax to PCRE

• convert either syntax to rx, an S-expression based regexp syntax

• untangle complex regexps by showing the parse tree in rx form and highlighting the corresponding chunks of code

• show the complete list of strings (productions) matching a regexp, provided the list is finite

• provide live font-locking of regexp syntax (so far only for Elisp buffers – other modes on the TODO list).

semantic-stickyfunc-mode shows the function point is currently in at the first line of the current buffer. This is useful when you have a very long function that spreads more than a screen, and you don't have to scroll up to read the function name and then scroll down to original position.

This package provides a blank-slate for users to define their own modal editing workflow. It has the following features, among others:

• The user can define custom states (like, say, normal, insert etc.) in any number at will;

• States may be buffer-local, allowing context-dependent configuration and behavior;

• States can hold settings such as cursor, keymaps and enter/exit hooks;

This package provides an org-mode link type that allows execution of various mu4e queries when clicked. Such links can be organized into a dashboard, by simply writing an org file.

This package calls mbsync from within Emacs.

Tshell is an experimental buffer-oriented shell. It supports shell and Emacs lisp commands.

The Detached package allows users to run processes detached from Emacs. It provides integration with multiple built-in modes, as well as providing an interface to attach and interact with the processes.

Pippel is an Emacs frontend for the Python package manager Pip. As Pippel also uses Tabulated List mode, it provides a similar package menu like package-list-packages.

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.

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

This library defines a face named parenthesis used just for parentheses. The intended purpose of this face is to make parentheses less visible in Lisp code by dimming them. Lispers probably don't need to be constantly made aware of the existence of the parentheses. Dimming them might be even more useful for people new to Lisp who have not yet learned to subconsciously blend out the parentheses.

Org mode supports inline image previews of LaTeX fragments. This package automates this, so fragment previews are disabled for editing when your cursor steps onto them, and re-enabled when the cursor leaves.

This package provides an Emacs minor mode to extend org-mode with Trello abilities. Trello is an online project organizer.

Emacs Langtool offers a frontend to LanguageTool server.

erc-scrolltoplace is an ERC module to try to emulate scrolltobottom while keep-place is enabled.

This package gives an overview of the current regex search candidates. The search regex can be split into groups with a space. Each group is highlighted with a different face.

It can double as a quick `regex-builder', although only single lines will be matched.

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 evil-mode functions for using selected text to search.

This package provides a way to REPL into a new Firefox instance's JavaScript engine. A new throwaway Firefox profile directory is created before each run, so you won't need to modify your existing profiles. This mode takes care of starting the new Firefox process in debugging mode, which may be tedious to do by hand. This comint mode is barebones and unstructured, meant for quick JavaScript experiments.

This package provides an Emacs interface to LeetCode allowing users to log in and solve problems of their choice using Emacs.

This package provides functions for converting Unicode to ASCII.

This package provides quick navigation to a specific parent directory using Eshell.

This package provides a SOAP client to access web services.

This package displays a waveform of a sound file. You can then play or navigate through it.
