A Portable Emacs Library (APEL) is a library for making portable Emacs Lisp programs. APEL-LB is a variant of APEL, which features supports to latest Emacs.

This library provides an implementation of streams for Emacs. Streams are implemented as delayed evaluation of cons cells.

This package extends Ivy by showing more information in the minibuffer for each candidate. It adds columns showing buffer modes, file sizes, docstrings, etc. If emacs-all-the-icons is installed, it can show icons as well.

Packed provides some package manager agnostic utilities to work with Emacs Lisp packages. As far as Packed is concerned packages are collections of Emacs Lisp libraries that are stored in a dedicated directory such as a Git repository. And libraries are Emacs Lisp files that provide the correct feature (matching the filename).

Where a package manager might depend on metadata, Packed instead uses some heuristics to get the same information---that is slower and might also fail at times but makes it unnecessary to maintain package recipes.

This package contains a command to read Perl documentation in Emacs: M-x perl-doc. It uses two external commands which come with Perl: perldoc to locate the Perl documentation for the Perl modules installed on your system, and pod2html to format the documentation to HTML.

• Auto-completion,

• Insertion of cases,

• Fully explicit intros,

• Outlines, code folding, and jumping to definition,

• Help with errors,

• and more.

The denote-journal package makes it easier to use Denote for journaling. While it is possible to use the generic denote command (and related) to maintain a journal, this package defines extra functionality to streamline the journaling workflow.

auto-dictionary is a minor mode that hooks into Flyspell's on-the-fly spell checking and extends these checks to also detect language. Auto-dictionary then sets ispell-dictionary to use the detected language.

Skempo is an attempt to improve Emacs built-in Skeleton and Tempo templates. It tries to make a unified syntax for template definitions. It also adds tags and marks support for Skeleton, and Abbrev support for Tempo.

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.

Out-of-box, Citar provides default support for file-per-note bibliographic notes that are compatible with Org-Roam v2. This package integrates directly with the Org-Roam database, and provides the following additional features to Citar note support:
