About

Gnosis is a personal knowledge management and spaced repetition system for Emacs. It integrates two complementary subsystems in a single package: a Zettelkasten-style note system called nodes, and a flashcard-based self-testing system built around themata. Both subsystems share a single SQLite database, and their contents are designed to be linked together so that flashcard questions can refer directly to the notes they are drawn from.

The name gnosis (Greek: γνῶσις, knowledge) reflects the package’s philosophical orientation: the goal is not mere memorization but the deliberate construction of knowledge over time.

Why Gnosis

Most spaced repetition tools treat flashcards as isolated units. You create a card, review it, and the system schedules the next review. The cards have no relationship to each other or to anything outside the review loop.

Most note-taking tools do the opposite: they help you build a web of interconnected ideas, but they offer no mechanism for systematically testing and reinforcing what you have written.

Gnosis bridges these two approaches. Your notes and your review material live in the same system, linked together. When you write a node about a topic, you can create themata whose questions reference that node. When you review, you can review all the questions linked to a given note, or follow the link graph to review related topics. The goal is a single system where understanding and recall reinforce each other.

Installation

Gnosis is available via GNU ELPA, & GNU Guix

Example using use-package

(use-package gnosis
  :init
  (define-prefix-command 'my/gnosis-map)
  (define-prefix-command 'my/gnosis-nodes-map)

jabber.el is an XMPP client for Emacs.

See the xmpp.org page for the full list of supported XEPs.

• Homepage

• Source:

  • Upstream
  • Codeberg Mirror

Requirements

• Emacs 29.1 or later, compiled with dynamic module support

OMEMO encryption (optional)

OMEMO end-to-end encryption requires building a native C module. You need a C compiler, pkg-config, and libmbedtls (the development headers). On first load, Emacs will prompt to build the module automatically.

Installation

jabber.el is available via NonGNU ELPA.

You can install it via M-x package-install RET jabber

package-vc (Emacs 30+)

(use-package jabber
  :ensure nil
  :vc (:url "https://git.thanosapollo.org/emacs-jabber/"
            :branch "master"
            :rev :newest
            :lisp-dir "lisp")
  :custom
  (jabber-account-list '(("user@example.org")))
  :config
  (jabber-modeline-mode 1)
  :bind-keymap (("C-x C-j" . jabber-global-keymap))
  :hook (kill-emacs . jabber-disconnect))

GNU Guix

The repository ships a guix.scm that builds straight from the current working tree, so you never need to update hashes or pin a commit. Whatever is checked out is what gets installed. Picomemo is fetched as a pinned input by guix.scm, so the optional OMEMO submodule does not need to be initialised.

git clone https://git.thanosapollo.org/emacs-jabber/
cd emacs-jabber

One-shot install into your user profile:

guix package -f guix.scm

A development shell with all build dependencies:

guix shell -D -f guix.scm

To use emacs-jabber from a Guix Home configuration, load the package definition and reference it from your services:

(use-modules (gnu home)
             (gnu home services)
             (gnu home services guix)
             (gnu services)
             (guix channels)
             (guix gexp))

(define emacs-jabber-git
  (load "/path/to/emacs-jabber/guix.scm"))

(home-environment
 (packages (list emacs-jabber-git)))

Re-run guix home reconfigure after pulling new commits and the package will be rebuilt from the updated checkout.

Configuration

Accounts are configured via jabber-account-list. The simplest form uses auth-source ~/.authinfo.gpg for passwords:

(setq jabber-account-list '(("user@example.org")
                             ("second@account.org")))

With pass (password-store):

(setq jabber-account-list
      `(("user@example.org"
         (:password . ,(auth-source-pass-get 'secret "xmpp/example.org/user")))))

About

Yee(t) (You)Tube

This package provides the ability to scrape YouTube, with the results displayed in a tabulated list.

Core features include:

• Executing queries on YouTube
• Playing & Downloading video(s)
• A standalone, minimalist yt-dlp wrapper

This package does not use Invidious or YouTube’s API, just “parses” html & json.

Installation

YeeTube is available via MELPA

Example using use-package

(use-package yeetube
  :ensure t
  :init (define-prefix-command 'my/yeetube-map)
  :bind (("C-c y" . 'my/yeetube-map)
          :map my/yeetube-map
          ("s" . 'yeetube-search)
          ("b" . 'yeetube-play-saved-video)
          ("d" . 'yeetube-download-videos)
          ("p" . 'yeetube-mpv-toggle-pause)
          ("v" . 'yeetube-mpv-toggle-video)
          ("V" . 'yeetube-mpv-toggle-no-video-flag)
          ("k" . 'yeetube-remove-saved-video)))

Dependencies

• mpv
• yt-dlp

Debian/Ubuntu

$ sudo apt install mpv yt-dlp

Configuration

Media Player

By default yeetube-play-function is set to yeetube-mpv-play, you can use mpv.el, GNU/Emms or other similar packages like so:

(setf yeetube-play-function #'emms-play-url)

Make sure that the media player of your choice can directly play youtube urls.

Thumbnails

Disable thumbnails:

(setf yeetube-display-thumbnails-p nil)

Apply Filters

To filter the search results based on a specific criterion, you can modify the yeetube-filter value to your preferred option.

For example:

(setf yeetube-filter "Views")

This will filter & sort the search results according to the number of views.

Tor & torsocks support

For enhanced privacy, using tor & torsocks:

(setf yeetube-enable-tor t
      yeetube-mpv-enable-torsocks t) ;; if you are using yeetube-mpv as your media player

It’s recommended to disable thumbnail support to imrpove performance when using tor.

Yeetube is configured to use tor via port 9050.

You can toggle that option for mpv with yeetube-mpv-toggle-torsocks
