SRV implements RFC 2782 (SRV records). It is used to look up hostname and port for a service at a specific domain. There might be multiple results, and the caller is supposed to attempt to connect to each hostname+port in turn.

AUCTeX is a comprehensive customizable integrated environment for writing input files for TeX, LaTeX, ConTeXt, Texinfo, and docTeX using Emacs or XEmacs.

This Emacs package provides the adaptive-wrap-prefix-mode minor mode which sets the wrap-prefix property on the fly so that single-long-line paragraphs get word-wrapped in a way similar to what you'd get with M-q using adaptive-fill-mode, but without actually changing the buffer's text.

This package provides an AES algorithm for encrypting and decrypting strings in Emacs. The supported algorithm is chosen to ensure interoperability with openssl.

Citeproc-el is an Emacs Lisp library for rendering citations and bibliographies in styles described in the Citation Style Language (CSL), an XML-based, open format to describe the formatting of bibliographic references.

This package provides Ukrainian holidays for Emacs calendar.

Picpocket is an image viewer for GNU Emacs. It has commands for:

• File operations on the picture files (delete, move, copy, hardlink).

• Scale and rotate the picture.

• Associate pictures with tags which are saved to disk.

• Filter pictures according to tags.

• Customizing keystrokes for quick tagging and file operations.

• Undo and browse history of undoable commands.

Js2 mode provides a JavaScript major mode for Emacs that is more advanced than the built-in javascript-mode. Features include accurate syntax highlighting using a recursive-descent parser, on-the-fly reporting of syntax errors and strict-mode warnings, smart line-wrapping within comments and strings, and code folding.

This package extends the built-in Save-Place mode by adding support for PDF view (see emacs-pdf-tools). This package will store the place (e.g., the current page and zoom) of PDF buffers under PDFView mode or DocView mode, and revisiting those PDF files later using the same mode will restore the saved place.

This is XML/XHTML done with S-Expressions in EmacsLisp. Simply, this is the easiest way to write HTML or XML in Lisp. This library uses the native form of XML representation as used by many libraries already included within Emacs. See esxml-to-xml for a concise description of the format.

Aim for this project is to make it easier to generate preprocessor macros from Emacs for C/C++ code that needs to be build against multiple incompatible versions of third party libraries or C++ standards.

Emacs::PDE is a collection of Emacs Lisp extensions to facilitate Perl programming. CPerl Mode has provided an excellent environment for coding; Emacs::PDE provides other common tools such as creating files using templates, smart compiling, perldoc, perltidy, debugger, tags tree view and so on. PDE also provides an easy configuration for Perl programming, and a tutorial for novices to start using Emacs.

Font Lock Studio is an interactive debugger for Emacs syntax highlighting rules, also called Font Lock keywords. It can single-step Font Lock keywords -- matchers, highlights, and anchored rules, to see what happens when a buffer is fontified. Breakpoints can be set on or inside rules. When inside a rule, matches are visualized using a palette of background colors. The explainer can describe a rule in plain-text English. Finally, tight integration with Edebug allows stepping into Lisp expressions that are part of the Font Lock keywords.

Scratch is an extension to Emacs that enables one to create scratch buffers that are in the same mode as the current buffer. This is notably useful when working on code in some language; you may grab code into a scratch buffer, and, by virtue of this extension, do so using the Emacs formatting rules for that language.

eless provides a combination of Bash script and a minimal Emacs view-mode.

Features:

• Independent of a user’s Emacs config.

• Customizable via the (locate-user-emacs-file "elesscfg") config.

• Not require an Emacs server to be already running.

• Syntax highlighting.

• Org-mode file rendering.

• man page viewer.

• Info viewer.

• Dired, wdired, (batch edit symbolic links).

• Colored diffs, git diff, git log, ls with auto ANSI detection.

• Filter log files lines matching a regexp.

• Auto-revert log files similar to tail -f.

• Quickly change frame and font sizes.

This is a Helm interface to Company mode, a text completion framework.

This package provides a series of rules and helper functions to prevent advertisers from tracking you when you open URLs (or listen to podcasts) in Emacs.

This backend for Company allows for C++ code completion with Irony mode using Clang tooling.

Combobulate is a package that adds structured editing and movement to a wide range of programming languages. Unlike most programming major modes that use error-prone imperative code and regular expressions to determine what's what in your code, Combobulate uses Emacs 29's tree-sitter library. Tree-sitter maintains a concrete syntax tree of your code; it gives Combobulate absolute clarity of all aspects of your code, enabling more correct movement and editing than you would otherwise have.

This package provides commands for increasing or decreasing the default font size in all GUI Emacs frames.

Evil escape provides a customizable key sequence to escape from insert state and everything else in Emacs.

Citre is an advanced Ctags (or actually, readtags) frontend for Emacs. It offers Completion At Point, Xref and Imenu integration. It also provides a Completing Read UI for jumping to definition and a powerful code reading tool that lets you go down the rabbit hole without leaving current buffer.

This package runs a callback (a finalizer) after its registered lisp object has been garbage collected. This allows extra resources, such as buffers and processes, to be cleaned up after the object has been freed.

The minitest mode provides commands to run the tests for the current file or line, as well as rerunning the previous tests, or all the tests for a project.

This package also includes relevant snippets for yasnippet.
