* Introduction
The following applications are not needed. I alternate between trying to /stay in Emacs/ taking advantage of the consistent interface, and using a stand-alone app on my Workday computer.
* Federation
** Mastodon
Glad to see the 2FA feature is working on the [[https://codeberg.org/martianh/mastodon.el][mastodon.el]] project, and even more glad to see the great birdland diaspora arrive in the land of the toots.
#+begin_src emacs-lisp
  (use-package mastodon
    :straight (:host codeberg :repo "martianh/mastodon.el")
    :init
    (setq mastodon-instance-url "https://emacs.ch"
          mastodon-active-user "howard"))
#+end_src

I would like a dedicate perspective to Mastodon, and I would like a leader key sequence that /expands/ will all options, once Mastodon is running in its own perspective:
#+begin_src emacs-lisp
  (use-package mastodon
    :config
    (ha-leader "a m" `("mastodon" . ,(ha-app-perspective "mastodon" #'mastodon)))

    (use-package major-mode-hydra
      :config
      (major-mode-hydra-define mastodon-mode nil
        ("Timelines"
         (("u" mastodon-tl--update "update")
          ("F" mastodon-tl--get-federated-timeline "Federated")
          ("H" mastodon-tl--get-home-timeline "Home")
          ("L" mastodon-tl--get-local-timeline "Local")
          ("T" mastodon-tl--get-tag-timeline "Hashtag"))
         "Specials"
         (("M" mastodon-notifications--get-mentions "Mentions")
          ("N" mastodon-notifications-get "Notifications")
          ("A" mastodon-tl--followed-tags-timeline "All Tags")
          ("S" mastodon-profile--view-bookmarks "Saved bookmarks")
          ("O" mastodon-profile--my-profile "My Profile"))
         "Post"
         (("c" mastodon-toot "Compose toot")
          ("e" mastodon-toot--edit-toot-at-point "Edit toot")
          ("t" mastodon-tl--thread "Read thread")
          ("r" mastodon-toot--reply "Reply")
          ("m" mastodon-tl--dm-user "Direct Msg")
          ("d" mastodon-toot--delete-toot "Delete"))
         "Toot"
         (("f" mastodon-toot--toggle-favourite "Favorite")
          ("b" mastodon-toot--toggle-boost "Boost")
          ("s" mastodon-toot--toggle-bookmark "Save")
          ("y" mastodon-toot--copy-toot-url "Copy URL")
          ("Y" mastodon-toot--copy-toot-text "Copy text"))
         "Navigation"
         (("n" mastodon-tl--next-tab-item "next" :color pink)
          ("p" mastodon-tl--previous-tab-item "previous" :color pink))))))
#+end_src

Let’s turn on non-fixed-width fonts to make everything easier to read:
#+begin_src emacs-lisp
  (use-package mastodon
     :hook (mastodon-mode . mixed-pitch-mode))
#+end_src
#+end_src
** Matrix/Element
Yet another encrypted chat/VoIP client-server, but unlike Signal and Telegram, [[matrix.org][Matrix]] is act ually open source. In other words, a project for nerds. We’ll be using Alphapapa’s latest [[https://github.com/alphapapa/ement.el][ement]] project.
#+begin_src emacs-lisp
  (use-package ement
    :straight (:host github :repo "alphapapa/ement.el")
    :config
    (defun ha-ement-connect ()
      (interactive)
      (let* ((auth-results (auth-source-search :host "howardism-matrix"))
             (auth-first   (first auth-results))
             (username     (plist-get auth-first :user))
             (password     (funcall (plist-get auth-first :secret))))
        (ement-connect :user-id username
                       :password password
                       :uri-prefix "https://howardism.org"))

      (ha-leader
          "a x S" '("send" . ement-send-direct-message)
          "a x s" '("send" . ement-room-send-message)
          "a x c" '("compose" . ement-room-compose-message)
          "a x r" '("room" . ement-view-room)))

    (ha-leader
      "a x"   '(:ignore t :which-key "matrix")
      "a x x" '("connect" . ha-ement-connect)
      "a x s" '("send" . ement-send-direct-message)))
#+end_src

Perhaps we can make it more attractive:
#+begin_src emacs-lisp
  (use-package ement
    :hook (ement-room-mode . ha-textual-litagures)
    :custom-face
    (ement-room-self-message ((t (:inherit variable-pitch :height 1.0))))
    (ement-room-message-text ((t (:inherit variable-pitch :height 1.1 :foreground "#f08c60"))))
    :init
    (setq ement-save-sessions t
          ement-room-avatars nil
          ement-room-timestamp-format ""
          ement-room-send-message-filter 'ement-room-send-org-filter))
#+end_src
* Other
** Twitter
The venerable [[https://github.com/hayamiz/twittering-mode/tree/master][twittering-mode]] allows me to follow all the twits.
#+begin_src emacs-lisp :tangle no
  (use-package twittering-mode
    :init
    (setq twittering-use-master-password t
          epa-pinentry-mode 'loopback)
    :config
    (defalias 'epa--decode-coding-string 'decode-coding-string)
    (ha-leader "a t" '("twitter" . twit)))
#+end_src
And we are no longer using this package.
** Telega
I'm thinking the [[https://zevlg.github.io/telega.el/][Telega package]] would be better than Bitlbee for Telegram communication.
#+begin_src emacs-lisp
  (use-package telega
    :config
    (setq telega-user-use-avatars nil
          telega-use-tracking-for nil ; '(any pin unread)
          telega-chat-use-markdown-formatting t
          telega-emoji-use-images t
                                          ; telega-completing-read-function #'ivy-completing-read
          telega-msg-rainbow-title nil)

    (when (fboundp 'evil-insert-state)
      (add-hook 'telega-chat-mode-hook 'evil-insert-state))

    (ha-leader "a t" `("telega" . ,(ha-app-perspective "telega" #'telega))))
#+end_src
For some reason, you need [[https://github.com/Fanael/rainbow-identifiers][rainbow-identifiers]] to work, oh, I guess the docs state this.

In the Telega chat’s, let’s turn on non-fixed-width fonts:
#+begin_src emacs-lisp
  (use-package telega
     :hook (telega-chat-mode . mixed-pitch-mode))
#+end_src
* RPG DM
Been working on my [[https://gitlab.com/howardabrams/emacs-rpgdm][RPG DM project]] for getting Emacs helping as a /Dungeon Master's Assistant/. The idea is to be able to roll dice and whatnot. What I find most useful is the [[https://gitlab.com/howardabrams/emacs-rpgdm/-/blob/main/rpgdm-tables.el][random tables]].
#+begin_src emacs-lisp
  (when (f-directory? "~/other/emacs-rpgdm")
    (use-package rpgdm
      :straight (:local-repo "~/other/emacs-rpgdm")
      :commands (rpgdm-mode rpgdm-tables-load)
      :init (setq rpgdm-base (expand-file-name "~/other/emacs-rpgdm"))
      :config (ha-leader "t D" '("rpg dm" . rpgdm-mode))))
#+end_src

And my [[https://gitlab.com/howardabrams/emacs-ironsworn][new Ironsworn project]] expands on it, giving me both the Oracles and the Moves. With an Org file, I can easily play Solo:
#+begin_src emacs-lisp
  (when (f-directory? "~/other/emacs-ironsworn")
    (use-package rpgdm-ironsworn
      :after rpgdm
      :straight (:local-repo "~/other/emacs-ironsworn")
      :init
      (setq rpgdm-ironsworn-project (expand-file-name "~/other/emacs-ironsworn")
            ;; Ignore org links that call my RPG functions:
            org-link-elisp-skip-confirm-regexp (rx string-start (optional "(") "rpgdm-"
                                                   (or "tables-" "ironsworn-")
                                                   (one-or-more any)))))
#+end_src
The project is interesting, and I should record a tutorial how to use it.
* Playing Music
Why not? Let’s see if the [[https://github.com/isamert/empv.el][empv]] project is sufficient. First install =mpv=, as in:
#+begin_src sh
  brew install mpv
#+end_src
What else?
#+begin_src emacs-lisp
  (use-package empv
    :straight (:host github :repo "isamert/empv.el")
    :general (ha-leader
               "a p" '(empv-map :wk "play music")))
#+end_src

* Technical Artifacts                                :noexport:
Let's =provide= a name so we can =require= this file:

#+begin_src emacs-lisp :exports none
  (provide 'ha-aux-apps)
  ;;; ha-aux-apps.el ends here
  #+end_src
