This Emacs package provides sequence manipulation functions that complement basic functions provided by subr.el. All its functions are prefixed with seq- and work on lists, strings, and vectors.

A package management library for Emacs, based on package.el.

The purpose of this library is to wrap all the quirks and hassle of package.el into a sane API.

Cov shows code coverage data for your program in Emacs. It supports currently gcov, lcov, coverage.py, and clover output, as well as the Coveralls format produced by Undercover.

Emacs Speaks Statistics (ESS) is an add-on package for GNU Emacs. It is designed to support editing of scripts and interaction with various statistical analysis programs such as R, Julia, and JAGS.

This package provides interfaces to abstract various LLMs out in the world. To respect user freedom, it will warn you before interacting with non-free LLMs.

Try is a package that allows you to try out Emacs packages without installing them. If you pass a URL to a plain text `.el`-file it evaluates the content, without storing the file.

Emacs Fuzzy Finder is like fzf, but it leverages the power of your Emacs instance to filter and select candidates. Use ezf as part of piping and command substitutions to manually select and filter matches.

aio is to Emacs Lisp as asyncio is to Python. This package builds upon Emacs generators to provide functions that pause while they wait on asynchronous events. They do not block any thread while paused.

This package extends Comint mode: it parses markup in the output stream, enabling plots and graphics to be embedded, and adds command-line functions which plug into Emacs (e.g., use :e <filename> to edit a file).

This package provides an FFI for Emacs. It is based on libffi and relies on the dynamic module support in order to be loaded into Emacs. It is relatively full-featured, but for the time being low-level.

This program is an asynchronous RPC stack for Emacs. Using this RPC stack, Emacs can communicate with the peer process smoothly. Because the protocol employs S-expression encoding and consists of asynchronous communications, the RPC response is fairly good.

csv.el provides functions for reading and parsing CSV files. It follows the format as defined in RFC 4180 Common Format and MIME Type for CSV Files (http://tools.ietf.org/html/rfc4180).

Lin is a stylistic enhancement for Emacs’ built-in Hl Line mode. It remaps the hl-line face (or equivalent) buffer-locally to a style that is optimal for major modes where line selection is the primary mode of interaction.

DVC is a legacy Emacs front-end for a number of distributed version control systems. It currently supports GNU Arch, GNU Bazaar, git, Mercurial, and Monotone. It also provides some integration with Gnus, e.g., for applying patches received by email.

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.

emacs-lin is a stylistic enhancement for Emacs’ built-in hl-line-mode. It remaps the hl-line face (or equivalent) buffer-locally to a style that is optimal for major modes where line selection is the primary mode of interaction.

This package provides a minor mode for Python that binds useful commands to unprefixed keys, such as j or e, under certain circumstances, and leaves the keys untouched outside of those situations, allowing unprefixed keys to insert their respective characters as expected.

Amx is an alternative interface for M-x in Emacs. It provides several enhancements over the ordinary execute-extended-command, such as prioritizing your most-used commands in the completion list and showing keyboard shortcuts, and it supports several completion systems for selecting commands, such as Ido and Ivy.

Flx provides fuzzy matching for emacs a la sublime text. The sorting algorithm is a balance between word beginnings (abbreviation) and contiguous matches (substring). The longer the substring match, the higher it scores. This maps well to how we think about matching. Flx has support for ido (interactively do things) through flx-ido.

This package provides transparent Age file encryption and decryption in Emacs. It is based on the Emacs EasyPG code and offers similar Emacs file handling for Age encrypted files: maintain .org.age encrypted Org files, provide Age encrypted authentication information out of .authinfo.age, open/edit/save Age encrypted files via Tramp...

Minibuffer and Completions in Tandem, also known as MCT, or mct.el, is an Emacs package that enhances the default minibuffer and *Completions* buffer so that they work together as part of a unified framework. The idea is to make the presentation and overall functionality be consistent with other popular, vertically aligned completion UIs while leveraging built-in functionality.

This package provides ivy-read as an alternative to completing-read and similar functions. No attempt is made to determine the best candidate. Instead, the user can navigate candidates with ivy-next-line and ivy-previous-line. The matching is done by splitting the input text by spaces and re-building it into a regular expression.

The Emacs IPython Notebook (EIN) package provides a Jupyter Notebook client and integrated REPL (like SLIME) in Emacs. EIN improves notebook editing by allowing you to use Emacs. It also expose IPython features such as code evaluation, object inspection and code completion. These features can be accessed anywhere in Emacs and improve Python code editing and reading in general in Emacs.

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.
