+WEBVTT
+
+00:02.960 --> 00:00:10.240
+Greetings. Salaam. This is Mohsen Banan.
+
+00:00:10.240 --> 00:00:14.080
+I am an Iranian software and internet engineer.
+
+00:14.080 --> 00:17.199
+I converted to Emacs in 1986.
+
+00:17.199 --> 00:20.480
+It was Emacs version 17 then.
+
+00:20.480 --> 00:00:23.920
+By around 1988, when Emacs version 18
+
+00:00:23.920 --> 00:00:25.680
+was well in place,
+
+00:00:25.680 --> 00:00:28.960
+I started living inside of Emacs.
+
+00:00:28.960 --> 00:00:31.119
+My primary digital environment
+
+00:00:31.119 --> 00:00:33.680
+has been Emacs ever since.
+
+00:33.680 --> 00:36.559
+It has been a good life.
+
+00:36.559 --> 00:40.000
+I'm a native Farsi speaker and writer.
+
+00:40.000 --> 00:00:41.520
+I'm not a linguist,
+
+00:00:41.520 --> 00:00:43.800
+and I do not specialize in
+
+00:43.800 --> 00:46.719
+multilingualization, internationalization,
+
+00:46.719 --> 00:48.879
+and localization.
+
+00:48.879 --> 00:52.239
+My favorite programming language is Lisp,
+
+00:52.239 --> 00:00:58.319
+and I am a bit of an Emacs developer.
+
+00:58.320 --> 01:00.719
+This presentation is about use of
+
+01:00.719 --> 01:04.000
+Perso-Arabic Scripts with Emacs.
+
+01:04.000 --> 01:06.720
+It's an overview presentation.
+
+01:06.720 --> 00:01:08.320
+I won't be digging deep
+
+00:01:08.320 --> 00:01:11.360
+in many of the mentioned topics.
+
+01:11.360 --> 00:01:13.119
+My goal is to make you aware
+
+00:01:13.119 --> 00:01:16.159
+of what can be done with Emacs today,
+
+01:16.159 --> 01:19.280
+and the potentials that Emacs presents
+
+01:19.280 --> 01:22.640
+for Perso-Arabic writers.
+
+01:22.640 --> 01:25.759
+The main topics that i'll cover are:
+
+01:25.759 --> 00:01:30.320
+- a brief introduction to Perso-Arabic scripts
+
+01:30.320 --> 01:35.119
+- two existing Emacs Persian input methods
+
+01:35.119 --> 00:01:36.960
+- the challenges involved with
+
+00:01:36.960 --> 00:01:42.960
+making Emacs applications bidirectional-aware
+
+01:42.960 --> 00:01:45.280
+- the ultimate goal of creating
+
+00:01:45.280 --> 00:01:47.759
+a complete digital environment
+
+00:01:47.759 --> 00:01:51.200
+for Perso-Arabic writers
+
+01:51.200 --> 00:01:57.679
+I'll also be including various pointers.
+
+01:57.680 --> 00:02:00.320
+So first, let's make sure
+
+00:02:00.320 --> 00:02:02.079
+that what I'm presenting
+
+00:02:02.079 --> 00:02:04.560
+is of interest to you.
+
+02:04.560 --> 00:02:07.040
+if you are a Perso-Arabic writer
+
+00:02:07.040 --> 00:02:08.879
+and if you use Emacs,
+
+00:02:08.879 --> 00:02:12.720
+you're definitely my intended audience.
+
+02:12.720 --> 00:02:15.120
+If you're an Emacs developer
+
+00:02:15.120 --> 00:02:19.120
+who wishes to make her Emacs apps
+
+02:19.120 --> 00:02:22.000
+multilingual and bidi-aware,
+
+00:02:22.000 --> 00:02:27.359
+you're also my intended audience.
+
+02:27.360 --> 00:02:30.480
+For the purposes of this presentation,
+
+00:02:30.480 --> 00:02:34.160
+in this slide, I'm categorizing scripts
+
+02:34.160 --> 02:39.040
+based on directionality and shaping.
+
+02:39.040 --> 00:02:41.280
+Latin letters are not shaped.
+
+00:02:41.280 --> 00:02:43.120
+Generally speaking,
+
+00:02:43.120 --> 00:02:44.800
+the shape of a Latin letter
+
+00:02:44.800 --> 00:02:49.599
+is independent of its position in a word.
+
+02:49.599 --> 00:02:53.280
+Perso-Arabic letters are subject to shaping.
+
+02:53.280 --> 02:56.319
+For example the letter mim--
+
+02:56.319 --> 02:58.800
+sounding similar to M--
+
+02:58.800 --> 03:01.840
+takes three shapes depending on whether
+
+03:01.840 --> 03:04.720
+it is in the beginning of a word,
+
+03:04.720 --> 00:03:06.480
+in the middle of a word,
+
+00:03:06.480 --> 00:03:09.200
+or at the end of a word.
+
+03:09.200 --> 00:03:12.159
+I'll be showing more of how shaping works
+
+00:03:12.159 --> 00:03:16.400
+in an Emacs session screencast later.
+
+03:16.400 --> 00:03:18.159
+Shaping has ramifications
+
+00:03:18.159 --> 00:03:21.040
+for Emacs application developers.
+
+03:21.040 --> 00:03:23.760
+For example, if you are combining
+
+00:03:23.760 --> 00:03:26.720
+initial letters to create a label,
+
+03:26.720 --> 03:29.680
+those letters can be shaped together--
+
+03:29.680 --> 03:31.760
+which is not what you want.
+
+03:31.760 --> 03:34.000
+In such cases, you would need to
+
+03:34.000 --> 03:37.840
+explicitly keep them separate.
+
+03:37.840 --> 00:03:40.799
+Latin-based scripts are always
+
+00:03:40.799 --> 00:03:42.560
+left-to-right.
+
+03:42.560 --> 00:03:46.560
+Perso-Arabic scripts are right-to-left
+
+03:46.560 --> 00:03:51.040
+with letters, but numbers are left-to-right.
+
+03:51.040 --> 00:03:53.040
+So, Perso-Arabic scripts
+
+00:03:53.040 --> 00:03:56.319
+are bi-directional (BIDI).
+
+03:56.319 --> 00:03:58.879
+Hebrew is also bi-directional,
+
+00:03:58.879 --> 00:04:02.159
+but Hebrew is not shaped.
+
+04:02.159 --> 00:04:05.680
+More recently, it has become very common
+
+00:04:05.680 --> 00:04:10.400
+to mix Perso-Arabic and Latin text.
+
+04:10.400 --> 00:04:12.560
+This can become very confusing
+
+00:04:12.560 --> 00:04:14.959
+if paragraph directionality
+
+00:04:14.959 --> 00:04:17.759
+is not properly observed.
+
+04:17.759 --> 00:04:20.000
+I'll be providing some examples
+
+00:04:20.000 --> 00:04:23.120
+as screencasts.
+
+04:23.120 --> 00:04:24.880
+The Emacs display engine
+
+00:04:24.880 --> 00:04:27.280
+now fully and well supports
+
+00:04:27.280 --> 00:04:32.079
+both shaping and BIDI.
+
+04:32.080 --> 00:04:37.120
+Since 2012, starting with Emacs version 24,
+
+04:37.120 --> 00:04:38.639
+we can say that Emacs
+
+00:04:38.639 --> 00:04:43.600
+is a truly multilingual-capable environment.
+
+04:43.600 --> 00:04:45.040
+Like everything else,
+
+00:04:45.040 --> 00:04:46.880
+multilingual support for Emacs
+
+00:04:46.880 --> 00:04:49.280
+was added gradually.
+
+04:49.280 --> 04:52.560
+Unicode support was added early on.
+
+04:52.560 --> 04:55.520
+The framework for input methods evolved
+
+04:55.520 --> 00:05:00.320
+in the 1990s. But it was not till version 24
+
+00:05:00.320 --> 00:05:03.360
+in 2012 that the display engine
+
+00:05:03.360 --> 00:05:06.240
+could fully support BIDI.
+
+05:06.240 --> 00:05:08.800
+Hats off to Eli Zaretskii
+
+00:05:08.800 --> 00:05:12.960
+for his work on Emacs BIDI.
+
+05:12.960 --> 00:05:15.600
+Once full BIDI support was in place
+
+00:05:15.600 --> 00:05:19.199
+in 2012, I went ahead and added
+
+00:05:19.199 --> 00:05:24.000
+two Persian input methods to Emacs 24.
+
+05:24.000 --> 00:05:26.400
+So now Emacs fully supports
+
+00:05:26.400 --> 00:05:30.638
+Perso-Arabic scripts.
+
+05:30.639 --> 00:05:34.080
+By Perso-Arabic script, we're referring to
+
+00:05:34.080 --> 00:05:36.320
+the Arabic writing system
+
+05:36.320 --> 00:05:38.160
+with various extensions
+
+00:05:38.160 --> 00:05:42.240
+used by a large number of languages.
+
+05:42.240 --> 00:05:44.479
+Perso-Arabic is the second most
+
+00:05:44.479 --> 00:05:47.520
+widely used writing system in the world
+
+05:47.520 --> 05:50.479
+by the number of countries.
+
+05:50.479 --> 05:54.000
+It is the third by the number of users
+
+05:54.000 --> 05:59.039
+after the Latin and Chinese scripts.
+
+05:59.039 --> 06:02.160
+So, by well supporting Perso-Arabic,
+
+06:02.160 --> 00:06:04.720
+Emacs's potential user base
+
+00:06:04.720 --> 00:06:09.918
+can be greatly enhanced.
+
+06:09.919 --> 00:06:12.960
+Before focusing on the Persian input methods,
+
+00:06:12.960 --> 00:06:14.960
+let me quickly summarize
+
+00:06:14.960 --> 00:06:18.319
+Emacs's input methods model.
+
+06:18.319 --> 00:06:21.360
+Input methods allow you to enter characters
+
+00:06:21.360 --> 00:06:25.120
+that are not supported by your keyboard.
+
+06:25.120 --> 00:06:29.280
+With Quail maps, we can map ASCII key strings
+
+00:06:29.280 --> 00:06:31.919
+to multilingual characters.
+
+06:31.919 --> 00:06:34.080
+So we can input any text
+
+00:06:34.080 --> 00:06:36.960
+from an ASCII keyboard.
+
+06:36.960 --> 00:06:38.960
+You select an input method
+
+00:06:38.960 --> 00:06:44.400
+with C-x RET C-\ .
+
+06:44.400 --> 00:06:49.918
+We'll try that in a screencast shortly.
+
+06:49.919 --> 00:06:53.919
+Since version 24, Emacs comes loaded with
+
+00:06:53.919 --> 00:06:56.880
+two Persian input methods:
+
+06:56.880 --> 00:07:01.520
+farsi-isiri-9147 is the standard
+
+00:07:01.520 --> 00:07:04.960
+traditional Iranian keyboard.
+
+07:04.960 --> 00:07:09.199
+farsi-transliterate-banan is an intuitive
+
+00:07:09.199 --> 00:07:12.319
+transliteration keyboard for Farsi
+
+00:07:12.319 --> 00:07:16.960
+which requires near-zero training for use.
+
+07:16.960 --> 00:07:18.960
+I'll be mostly focused on
+
+00:07:18.960 --> 00:07:21.520
+farsi-transliterate-banan
+
+00:07:21.520 --> 00:07:23.919
+in this presentation.
+
+07:23.919 --> 00:07:27.839
+So let's try this out.
+
+07:27.840 --> 07:30.319
+In this gif-cast, we're going to select
+
+07:30.319 --> 00:07:32.240
+a Persian input method
+
+00:07:32.240 --> 00:07:35.280
+and write a few simple sentences.
+
+07:35.280 --> 07:38.160
+With no training and no documentation,
+
+07:38.160 --> 00:07:41.360
+any Farsi writer familiar with Emacs
+
+00:07:41.360 --> 00:07:45.440
+can write these, as farsi-transliterate-banan
+
+00:07:45.440 --> 00:07:48.560
+input method is intuitive.
+
+07:48.560 --> 00:07:50.400
+I'll be using keycast
+
+00:07:50.400 --> 00:07:54.160
+to show you keys as they are used.
+
+07:54.160 --> 07:56.560
+Let me first describe as to what we have
+
+07:56.560 --> 07:58.720
+on the screen.
+
+07:58.720 --> 08:01.520
+There are three windows in one frame.
+
+08:01.520 --> 00:08:04.639
+Keycast will show commands and keys
+
+00:08:04.639 --> 00:08:06.319
+on the mode line.
+
+08:06.319 --> 00:08:08.639
+The leftmost window is showing
+
+00:08:08.639 --> 00:08:10.879
+logs of keycast.
+
+08:10.879 --> 08:14.639
+Transformed individual unshaped letters
+
+08:14.639 --> 08:17.360
+will appear here.
+
+08:17.360 --> 00:08:21.120
+The middle window is running a tail -f
+
+00:08:21.120 --> 00:08:27.440
+on the dribble file piped to fold -w1.
+
+08:27.440 --> 00:08:30.720
+This lets you see the raw ASCII characters
+
+00:08:30.720 --> 00:08:34.479
+as I type them.
+
+08:34.479 --> 00:08:37.839
+The right window is the empty buffer
+
+00:08:37.839 --> 00:08:41.680
+on the ex.fa file.
+
+08:41.680 --> 00:08:44.560
+Anything that I described here
+
+00:08:44.560 --> 00:08:49.040
+can be done with virgin Emacs distribution
+
+08:49.040 --> 08:51.360
+with nothing added,
+
+08:51.360 --> 08:53.760
+but I'm using Blee
+
+08:53.760 --> 08:57.120
+(By* Libre-Halaal Emacs Environment)
+
+08:57.120 --> 00:09:02.720
+to show things. You don't need to have blee
+
+00:09:02.720 --> 00:09:07.600
+for writing the equivalent of the text
+
+00:09:07.600 --> 00:09:10.800
+in this gif-cast.
+
+09:10.800 --> 00:09:13.440
+First, I'm going to select
+
+00:09:13.440 --> 00:09:16.800
+the farsi-transliterate-banan.
+
+09:16.800 --> 00:09:22.080
+I'm entering C-x RET C-\ .
+
+09:22.080 --> 00:09:23.839
+Notice the mode -ine
+
+00:09:23.839 --> 00:09:27.040
+and the prompt at mini-buffer.
+
+09:27.040 --> 09:30.399
+With completion, I'm going to select
+
+09:30.399 --> 09:34.000
+farsi-transliterate-banan.
+
+09:34.000 --> 00:09:38.560
+Notice that farsi-isiri-9147
+
+09:38.560 --> 09:43.360
+was also provided as a choice.
+
+09:43.360 --> 00:09:47.440
+Also notice that the letter 'b' appears
+
+00:09:47.440 --> 00:09:51.760
+in the left of the mode line of ex.fa.
+
+09:51.760 --> 00:09:54.000
+This indicates which input method
+
+00:09:54.000 --> 00:09:56.320
+has been selected.
+
+09:56.320 --> 00:09:58.560
+Also notice that cursor is on
+
+00:09:58.560 --> 00:10:04.399
+the top left corner of ex.fa.
+
+10:04.399 --> 10:08.800
+Next, I'm going to enter the 's' character.
+
+10:08.800 --> 10:12.000
+Notice the cursor moved to the right,
+
+10:12.000 --> 00:10:15.120
+and unshaped ’seen’ appeared
+
+00:10:15.120 --> 00:10:20.079
+in the ex.fa buffer, on the mode-line,
+
+10:20.079 --> 10:23.760
+and in the keycast log buffer.
+
+10:23.760 --> 00:10:28.000
+Next, I'm going to enter 'l'.
+
+10:28.000 --> 00:10:32.800
+Notice ل in the mode-line,
+
+10:32.800 --> 00:10:39.920
+and notice how س was subjected to shaping.
+
+10:39.920 --> 10:42.640
+Next I'm going to write the letter
+
+10:42.640 --> 10:44.640
+to write the following:
+
+10:44.640 --> 10:50.560
+ سلام –حال شما چه طوره؟ –با ایمکس همه کار میشه کرد
+
+10:50.560 --> 10:52.480
+"Hello, how are you?"
+
+10:52.480 --> 00:10:56.720
+You can do everything with Emacs.
+
+10:56.720 --> 11:00.000
+Generally, same-sounding Latin characters
+
+11:00.000 --> 00:11:03.920
+are used. As usual, vowels are ignored
+
+00:11:03.920 --> 00:11:06.720
+unless called for.
+
+11:06.720 --> 11:10.800
+Notice that in order to get ح,
+
+11:10.800 --> 11:14.560
+i repeated 'h' twice.
+
+11:14.560 --> 11:15.440
+
+11:15.440 --> 11:18.560
+is the obvious 'sh'.
+
+11:18.560 --> 11:19.519
+
+11:19.519 --> 11:22.480
+is the obvious 'ch'.
+
+11:22.480 --> 00:11:28.640
+t, that's the ط is upper case T.
+
+11:28.640 --> 00:11:29.439
+ ت
+
+00:11:29.439 --> 00:11:31.839
+is lowercase t.
+
+11:31.839 --> 11:34.880
+That's it. We managed to write in Farsi
+
+11:34.880 --> 11:38.640
+with a QWERTY keyboard, intuitively.
+
+11:38.640 --> 11:40.959
+Next, we are going to switch back to
+
+11:40.959 --> 00:11:45.680
+globish and write "back to globish".
+
+11:45.680 --> 00:11:47.920
+Notice that the globish sentence
+
+00:11:47.920 --> 00:11:50.959
+started from the left side.
+
+11:50.959 --> 00:11:53.279
+This is due to proper detection
+
+00:11:53.279 --> 00:12:00.159
+of paragraph directionality by Emacs.
+
+12:00.160 --> 00:12:05.600
+For the most part, Emacs is self-documenting.
+
+12:05.600 --> 12:07.920
+Here we are pointing you to some
+
+12:07.920 --> 12:12.880
+relevant self-contained Emacs resources.
+
+12:12.880 --> 00:12:15.680
+The BIDI documentation applies to
+
+00:12:15.680 --> 00:12:18.000
+all BIDI scripts,
+
+12:18.000 --> 12:22.079
+not just Perso-Arabic scripts.
+
+12:22.079 --> 00:12:23.279
+Referring to the code
+
+00:12:23.279 --> 00:12:27.999
+can also be useful for some.
+
+12:28.000 --> 12:30.079
+Here are some pointers.
+
+12:30.079 --> 00:12:32.399
+The Quail translation code
+
+00:12:32.399 --> 00:12:35.519
+for Persian input methods:
+
+00:12:35.519 --> 00:12:39.120
+the persian.el file has full details
+
+00:12:39.120 --> 00:12:43.999
+of the mapping and some documentation.
+
+12:44.000 --> 00:12:46.639
+Next, we'll show the keyboard layouts
+
+00:12:46.639 --> 00:12:51.519
+as a gif-cast. You can get
+
+00:12:51.519 --> 00:12:55.519
+relevant documentation for any input method
+
+12:55.519 --> 00:13:00.320
+with the describe-input-method command.
+
+13:00.320 --> 00:13:05.920
+So, let's try that for farsi-transliterate-banan.
+
+00:13:05.920 --> 00:13:09.360
+We are back in the ex.fa buffer
+
+00:13:09.360 --> 00:13:11.279
+as one window.
+
+13:11.279 --> 13:13.839
+We don't need the keycast logging
+
+13:13.839 --> 13:17.040
+and the dribble windows any more.
+
+13:17.040 --> 13:20.320
+With the C-\, I reactivate
+
+13:20.320 --> 13:23.360
+the farsi input method.
+
+13:23.360 --> 00:13:26.399
+Notice that keycast is still active
+
+00:13:26.399 --> 00:13:29.360
+on the mode line.
+
+13:29.360 --> 00:13:34.240
+Next, with the C-h C-\ ,
+
+00:13:34.240 --> 00:13:38.560
+I get the input methods documentation.
+
+13:38.560 --> 00:13:40.639
+I then delete other windows
+
+00:13:40.639 --> 00:13:45.440
+and keep the help buffer visible.
+
+13:45.440 --> 00:13:47.279
+Notice that beh
+
+00:13:47.279 --> 00:13:52.720
+in this input methods identifier.
+
+13:52.720 --> 13:55.920
+Here is the URL for full documentation
+
+13:55.920 --> 00:14:00.639
+on the web. The keyboard layout itself
+
+00:14:00.639 --> 00:14:03.760
+is a one-to-one mapping, but towards
+
+00:14:03.760 --> 00:14:07.360
+making transliteration intuitive.
+
+14:07.360 --> 14:10.240
+Multiple keys are sometimes mapped to
+
+14:10.240 --> 14:12.079
+the same letter.
+
+14:12.079 --> 00:14:19.760
+For example, both 'i' and 'y' produce yeh.
+
+14:19.760 --> 14:22.959
+The usual two letter transliterations
+
+14:22.959 --> 00:14:29.600
+ending with 'h' -- zh, ch, sh, and kh
+
+00:14:29.600 --> 00:14:34.160
+are provided. The ampersand prefix
+
+00:14:34.160 --> 00:14:37.440
+is used to support often invisible
+
+14:37.440 --> 00:14:41.600
+BIDI markings. In addition to this
+
+00:14:41.600 --> 00:14:43.920
+internal documentation,
+
+00:14:43.920 --> 00:14:48.958
+full documentation is also available.
+
+14:48.959 --> 00:14:50.560
+Complete documentation
+
+00:14:50.560 --> 00:14:52.240
+for Persian input methods
+
+00:14:52.240 --> 00:14:58.560
+is available as PLPC-120036.
+
+14:58.560 --> 00:15:00.880
+Next, we'll take a quick look at this
+
+00:15:00.880 --> 00:15:03.600
+on the web.
+
+15:03.600 --> 00:15:05.440
+You can click on links
+
+00:15:05.440 --> 00:15:07.440
+in the reveal web-based form
+
+00:15:07.440 --> 00:15:09.839
+of this presentation.
+
+15:09.839 --> 15:15.440
+So let's visit PLPC-120036.
+
+15:15.440 --> 00:15:17.600
+This document fully describes
+
+00:15:17.600 --> 00:15:20.560
+Persian input methods.
+
+15:20.560 --> 00:15:22.320
+In addition to HTML,
+
+00:15:22.320 --> 00:15:26.079
+you can also obtain it in PDF.
+
+00:15:26.079 --> 00:15:30.079
+Let's do that. Of particular interest
+
+00:15:30.079 --> 00:15:33.120
+in this document are various tables
+
+15:33.120 --> 00:15:35.839
+that enumerate lists of letters
+
+00:15:35.839 --> 00:15:37.120
+with their association
+
+00:15:37.120 --> 00:15:41.839
+to both Persian input methods.
+
+15:41.839 --> 15:46.240
+Let's take a look at a few of these.
+
+15:46.240 --> 00:15:51.360
+Table 3, mapping of isiri-6219
+
+15:51.360 --> 15:53.680
+(the Farsi character set)
+
+15:53.680 --> 00:15:55.680
+to Emacs version input methods
+
+00:15:55.680 --> 00:15:58.720
+could be of interest to you,
+
+15:58.720 --> 16:01.040
+as well as table 8
+
+16:01.040 --> 16:04.720
+for BIDI-related control markups,
+
+16:04.720 --> 00:16:17.518
+and table 9, for vowels and other signs.
+
+16:17.519 --> 00:16:19.759
+Having covered input methods,
+
+00:16:19.759 --> 00:16:21.279
+let's turn our attention
+
+00:16:21.279 --> 00:16:25.199
+to ramifications of BIDI and Perso-Arabic
+
+00:16:25.199 --> 00:16:28.480
+on various Emacs applications.
+
+16:28.480 --> 00:16:32.160
+Since 2012, I have been using Persian text
+
+00:16:32.160 --> 00:16:35.839
+in various Emacs applications.
+
+16:35.839 --> 00:16:38.079
+In short, my experience has been
+
+00:16:38.079 --> 00:16:42.399
+that most Emacs apps are usable,
+
+16:42.399 --> 16:44.880
+but they all have glitches
+
+16:44.880 --> 00:16:47.279
+that could at a minimum
+
+00:16:47.279 --> 00:16:51.279
+annoy Perso-Arabic users.
+
+16:51.279 --> 16:54.639
+In this slide, I'm presenting a summary.
+
+16:54.639 --> 00:16:56.399
+The glitches with Gnus
+
+00:16:56.399 --> 00:17:00.079
+are not all that significant for me.
+
+17:00.079 --> 17:04.240
+BBDB glitches can easily be fixed.
+
+17:04.240 --> 00:17:07.679
+For Calendar, I have customized my own setup
+
+00:17:07.679 --> 00:17:10.799
+to support Persian and Islamic dates
+
+00:17:10.799 --> 00:17:14.079
+in Perso-Arabic. Perhaps they should be
+
+00:17:14.079 --> 00:17:17.039
+merged upstream, instead of
+
+00:17:17.039 --> 00:17:19.679
+dealing with apps one at a time.
+
+00:17:19.679 --> 00:17:21.439
+I think it's more reasonable
+
+00:17:21.439 --> 00:17:25.279
+to consider them collectively.
+
+17:25.280 --> 00:17:26.880
+The glitches that I mentioned
+
+00:17:26.880 --> 00:17:28.799
+in the previous slide
+
+17:28.799 --> 17:30.480
+have two routes:
+
+17:30.480 --> 17:32.480
+some are BIDI-specific
+
+17:32.480 --> 17:35.919
+and some are Perso-Arabic-specific.
+
+17:35.919 --> 00:17:36.720
+In this slide,
+
+00:17:36.720 --> 00:17:39.280
+I have classified them as such
+
+17:39.280 --> 17:42.960
+and have made some general suggestions,
+
+17:42.960 --> 00:17:45.679
+but all of these at best amount to
+
+00:17:45.679 --> 00:17:47.679
+tactical approaches.
+
+17:47.679 --> 00:17:50.160
+I think a more strategic approach
+
+00:17:50.160 --> 00:17:53.519
+is called for.
+
+17:53.520 --> 17:56.240
+The right way to address BIDI-awareness
+
+17:56.240 --> 17:58.559
+and other awarenesses
+
+17:58.559 --> 00:18:00.559
+is to build them in frameworks
+
+00:18:00.559 --> 00:18:04.160
+that Emacs apps can then use.
+
+18:04.160 --> 00:18:08.480
+So, I'm proposing that we first create ENML,
+
+00:18:08.480 --> 00:18:11.520
+the Emacs Native Markup Language,
+
+00:18:11.520 --> 00:18:16.880
+as a Lisp-ish (perhaps even not fully secure)
+
+18:16.880 --> 18:20.320
+super-set of HTML5.
+
+18:20.320 --> 18:22.960
+With that in place, we can then build on
+
+18:22.960 --> 00:18:25.360
+the two decades of experience
+
+00:18:25.360 --> 00:18:27.600
+that have produced various
+
+00:18:27.600 --> 00:18:31.039
+web application development frameworks
+
+18:31.039 --> 18:33.919
+by mimicking one of them.
+
+18:33.919 --> 00:18:35.679
+I don't have any running code
+
+00:18:35.679 --> 00:18:39.440
+for any of these, but discussing strategy
+
+00:18:39.440 --> 00:18:44.639
+need not always be futile.
+
+18:44.640 --> 18:47.679
+Emacs has immense potentials,
+
+18:47.679 --> 18:51.120
+but those potentials cannot be realized
+
+18:51.120 --> 00:18:54.640
+unless we integrate Emacs in the totality
+
+00:18:54.640 --> 00:18:59.840
+of a specific complete digital ecosystem.
+
+18:59.840 --> 19:02.000
+Over the past two decades, I've been
+
+19:02.000 --> 00:19:03.440
+building the contours
+
+00:19:03.440 --> 00:19:06.240
+of The Libre-Halaal By* (ByStar)
+
+00:19:06.240 --> 00:19:10.240
+digital ecosystem.
+
+19:10.240 --> 19:13.039
+Emacs can then be fully integrated into
+
+19:13.039 --> 00:19:16.799
+ByStar. It's through such integration
+
+00:19:16.799 --> 00:19:19.679
+that full conviviality of Emacs
+
+00:19:19.679 --> 00:19:24.239
+can be experienced.
+
+19:24.240 --> 00:19:26.640
+Blee, the ByStar Libre-Halaal
+
+00:19:26.640 --> 00:19:30.000
+Emacs environment is Emacs
+
+00:19:30.000 --> 00:19:32.720
+plus a whole lot of Emacs apps
+
+00:19:32.720 --> 00:19:34.880
+integrated with Debian,
+
+00:19:34.880 --> 00:19:38.320
+With ByStar services and with BISOS,
+
+00:19:38.320 --> 00:19:42.480
+the ByStar Internet Services OS.
+
+19:42.480 --> 00:19:43.600
+Perhaps this could be
+
+00:19:43.600 --> 00:19:45.840
+the topic of a presentation
+
+00:19:45.840 --> 00:19:46.840
+for the 2022 Emacs Conference.
