;; «intro» (to ".intro")
;;
;; 1. Introduction
;; ===============
;; Some parts of eev call external programs:
;;
;; (find-eev-quick-intro "3.1. Non-elisp hyperlinks")
;; (find-eev-quick-intro "3.1. Non-elisp hyperlinks" "firefox")
;; (find-eev-quick-intro "3.1. Non-elisp hyperlinks" "chrome")
;; (find-eev-quick-intro "6.2. Other targets")
;; (find-eev-quick-intro "6.2. Other targets" "python")
;; (find-psne-intro "1. Local copies of files from the internet")
;; (find-psne-intro "1. Local copies of files from the internet" "wget")
;; (find-video-links-intro "1. Introduction")
;; (find-video-links-intro "1. Introduction" "[Video links:]")
;; (find-video-links-intro "5.1. Subtitles")
;; (find-audiovideo-intro "4.3. A demo")
;; (find-audiovideo-intro "4.3. A demo" "mpv")
;; (find-pdf-like-intro "3. Hyperlinks to PDF files")
;; (find-pdf-like-intro "3. Hyperlinks to PDF files" "xpdf")
;; (find-pdf-like-intro "3. Hyperlinks to PDF files" "pdftotext")
;;
;; On *NIX systems the installation of these programs is easy, and no
;; configuration is needed - if "firefox", "google-chrome", "python3",
;; "wget", "xpdf", "pdftotext", and "mpv" are in the path then eev
;; simply calls them with the right arguments, and (usually)
;; everything works.
;;
;; On M$ Windows things are much harder: 1) eev needs to know the full
;; paths of the ".exe"s of these programs, 2) wget and pdftotext are
;; hard to install, 3) it is better to use a browser to open PDFs, 4)
;; I don't have access to a machine with Windows, 5) I have very
;; little access to people who use Windows and who can be convinced to
;; test this...
;;
;; This file is an attempt to solve this problem both "without magic"
;; and "with very little magic". Remember that:
;;
;; "Any sufficiently advanced technology
;; is indistinguishable from magic"
;;
;; Here I will use the term "magic" as a shorthand for a "sufficiently
;; advanced technology", i.e., something complex and non-obvious,
;; "that is indistinguishable from magic", in the sense of being
;; almost impossible to understand. I will also use "black box" as a
;; near-synonym for "magic"; "black box" has more letters than
;; "magic", but it invites us to use expressions like "opening the
;; black box".
;;
;; In dec/2021 I recorded a video, called "Org for Non-Users",
;;
;; http://anggtwu.net/2021-org-for-non-users.html
;; (find-1stclassvideo-links "2021orgfornonusers")
;; (find-1stclassvideoindex "2021orgfornonusers")
;;
;; in which I explained why I always found Org so hard to learn. Many
;; things in Org are implemented in ways that I don't understand, and
;; practically every time that I try to learn more features of Org I
;; start to ask questions like "hey, how is this implemented?", and I
;; get stuck trying to answer these "non-user" questions instead of
;; simply learning how to use the feature "as a user"...
;;
;; In the language of black boxes what happens when I try to learn Org
;; is this. I try to learn a new feature; I see lots of black boxes; I
;; try to open these black boxes, and fail miserably; I get frustrated
;; and exhausted; I postpone learning that feature to another day.
;;
;; I have the same relationship with `M-x customize'.
;;
;; The most "user-friendly" way to configure Emacs is with
;; `customize'. Try:
;;
;; (eek "M-x customize")
;; (customize-group 'processes)
;; (customize-group 'shell)
;; (customize-variable 'explicit-bash-args)
;; (customize-face 'eev-glyph-face-red)
;;
;; Over the years I have experimented with several alternatives to
;; customize that "use less magic". This page,
;;
;; http://anggtwu.net/eev-customize.html
;;
;; from april/2022, describe some of my experiments.
;;
;; I started to work on eev-wconfig.el a few days after making that
;; page. Eev-wconfig.el uses all the ideas there, plus a few new ones.
;;
;; Eev-wconfig can be used both "with no magic" and "with some magic".
;; Both ways create temporary buffers that have parts that perform
;; configuration steps and parts with elisp hyperlinks "that open the
;; (black) boxes" and explain what the configuration steps do.
;;

;; To use this, run:
;;
;; (find-wconfig-links)

;; The `(find-wconfig-links)' will create a temporary buffer with
;; instructions. For more info, see the video:

;; 0. The variable
;; ===============
;; See: (find-elisp-intro \"5. Variables\")
;; The current value of the variable `ee-googlechrome-program' is:
(setq ee-googlechrome-program
\"{ee-googlechrome-program}\")
;; 1. Configure Chrome
;; ===================
;; Replace the string below by the full path of chrome.exe
;; and then execute the sexp below with `M-e'.
;; Note that you NEED to replace all the `\\'s in it by `/'s.
;;
(setq ee-googlechrome-program

;; 2. Tests
;; ========
;; Try:
;; (find-googlechrome \"https://www.lua.org/\")
;; Also, the section 3.1 of the main tutorial describes a
;; quick way to open the \"url at point\" with `M-x brg'.
;; Try it:
;; (find-eev-quick-intro \"3.1. Non-elisp hyperlinks\")
;; 3. Update this page
;; ===================
;; See: (find-links-intro \"5. The first line regenerates the buffer\")
;; This page is generated by a template. Run the sexp in the
;; first line to regenerate this page and to make the first and
;; the last `setq's display the current value of the
;; variable `ee-googlechrome-program'.
;; 4. Save your configuration
;; ==========================
;; The \"init file\" is explained here: (find-enode \"Init File\")
;; Hint: `M-5 M-5 M-j' runs: (find-fline \"~/.emacs\")
;; See: (eek \"M-j\")

;; 5. Save some things to your ~/TODO
;; ==================================
;; Remember that you are encouraged to use the file ~/TODO as a messy
;; log file, and that you can access it with `M-1 M-j'. See:
;; (find-here-links-intro \"1. Alternating between \\\"task\\\" and \\\"notes\\\"\")

;; Copy the two uncommented sexps below to your ~/TODO, and save it:
(find-wconfig-links)
(find-wconfig-browser-links)
;; 6. Test your saved configuration
;; ================================
;; Open a second Emacs without closing this one, and check that in the
;; second Emacs you can run `M-x eev-beginner' to load eev and open
;; `(find-eev-quick-intro)'; then run `M-1 M-j' in the second Emacs to
;; access your ~/TODO, and check that the lines
;; (find-wconfig-links)
;; (find-wconfig-browser-links)
;; that you saved in the section 5 are there. Run the tests in the
;; section 2 of `(find-wconfig-browser-links)' and check that they
;; work - i.e., that the second Emacs is using the right value for the
;; variable `ee-googlechrome-program'.
