Emacs-doom-themes contains numerous popular color themes for Emacs that integrate with major modes like Org-mode.

This is a port of the themes in Vim-airline to Emacs Powerline.

DefaultEncrypt is designed to be used with Gnus in Emacs. It automatically encrypts messages that you send (e.g., email) when public keys for all recipients are available, and it protects you from accidentally sending un-encrypted messages. It can also be configured to automatically sign messages that you send. For details and instructions on how to use DefaultEncrypt, please refer to the home page or read the comments in the source file, jl-encrypt.el.

This package provides a hybrid of keyboard macros and yasnippet. You create the snippet on the go, usually to be used just in the one place. It's fast, because you're not leaving the current buffer, and all you do is enter the code you'd enter anyway, just placing ~ where you'd like yasnippet fields and mirrors to be.

RFCs and STDs are published in a simple text form. This package provides an Emacs major mode, rfcview-mode, which makes it more pleasant to read these documents in Emacs. It prettifies the text and adds hyperlinks/menus for easier navigation. It also provides functions for browsing the index of RFC documents and fetching them from remote servers or local directories.

This package stores uniform EIEIO objects in an EmacSQL database. SQLite is used as backend.

An implementation of the ChaCha20 encryption algorithm in Emacs Lisp.

This package prettifies headings and plain lists in Org mode. It is a direct descendant of org-bullets, with most of the code base completely rewritten.

Currently, this package prettifies Org heading lines by:

• replacing trailing bullets by UTF-8 bullets,

• hiding leading stars, customizing their look or removing them from vision,

• applying a custom face to the header bullet,

• applying a custom face to the leading bullets,

• using double-bullets for inline tasks,

• (optional) using special bullets for TODO keywords.

It also prettifies Org plain list bullets by:

• replacing each bullet type (*, + and -) with UTF-8 bullets,

• applying a custom face to item bullets.

Features degrade gracefully when viewed from terminal.
