Flymake collects diagnostic information for multiple sources, called backends, and visually annotates the relevant portions in the buffer.

The plz-event-source library provides a plz-media-type, a parser, and an event source implementation for the SSE protocol.

This package provides a global minor mode to inhibit screensaver activation in EXWM.

Posframe can pop a posframe at point. A posframe is a child frame displayed within its root window's buffer. Posframe is fast and works well with CJK languages.

This package provides an interface for selecting from different conversion recipes, often including tools like ffmpeg or convert. The conversion command need only be written once, and subsequent invocations can be readily customized. Several recipes are included by default, and more can be readily added.

This package provides a set of Emacs functions to search definitions of identifiers in the MIT-Scheme documentation.

This package provides functionality to search for a number up to the end of a line and increment or decrement it.

Kibit Helper provides functions to work with the Kibit Leiningen plugin for detecting and improve non-idiomatic Clojure source code.

Extmap is a very simple package that lets you build a read-only, constant database that maps Emacs Lisp symbols to arbitrary Emacs Lisp objects.

This package extends gptel, using that package to generate suggestions based on the user's request. Those code suggestions will then automatically be applied to the buffer in the format of a git merge.

This Emacs mode displays Hiragana and Katakana flashcards. It can use functionality from Emacs Kanji mode if it is installed.

visual-replace provides an alternate interface for search and replacement commands that supports previews. The interface also allows one to edit both the query-text and its replacement in the same minibuffer prompt. The interface covers the following commands:

1. replace-string

2. replace-regexp

3. query-replace

4. query-replace-regexp

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

This package replaces the traditional chevron citation marks > with a Unicode vertical bar with the same color as the text it is quoting.

It is purely presentation: the underlying text is unchanged. In particular, if you send a message containing a citation, it will contain the traditional chevron marks.

This package adds visual hints to certain Ex commands in Evil mode.

Magit-delta provides a minor mode which configures emacs-magit to use delta for syntax highlighting when displaying diffs.

This package helps you control your GNU/Linux desktop from Emacs. With desktop-environment, you can control the brightness and volume as well as take screenshots and lock your screen. The package depends on the availability of shell commands to do the hard work for us. These commands can be changed by customizing the appropriate variables.

Read-only-cfg is an Emacs minor mode that can automatically make files read-only based on user configuration. User configuration may be prefix directories or regex patterns.

This package implements the Growl Notification Protocol GNTP described at http://www.growlforwindows.com/gfw/help/gntp.aspx. It is incomplete as it only lets you send but not receive notifications.

darkroom-mode makes visual distractions disappear. The mode-line is temporarily elided, text is enlarged and margins are adjusted so that it's centered on the window.

darkroom-tentative-mode is similar, but it doesn't immediately turn-on darkroom-mode, unless the current buffer lives in the sole window of the Emacs frame (i.e. all other windows are deleted). Whenever the frame is split to display more windows and more buffers, the buffer exits darkroom-mode. Whenever they are deleted, the buffer re-enters darkroom-mode.

elisp-refs finds references to functions, macros or variables. Unlike a dumb text search, it actually parses the code, so it's never confused by comments or foo-bar matching foo.

This package provides an Emacs package for more context in compilation/grep buffers. Works with wgrep, ack, ag, ivy.

This package provides a Hydra menu for interacting with the Pandoc, the document-conversion tool.

This package provides a Helm interface to run operations on removable volumes in Linux.
