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

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.

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. + +00:19:46.840 --> 00:19:51.559 +[captions by Mohsen Banan] diff --git a/2021/info/bidi-schedule.md b/2021/info/bidi-schedule.md index a4504914..0657e4ef 100644 --- a/2021/info/bidi-schedule.md +++ b/2021/info/bidi-schedule.md @@ -1,13 +1,17 @@ Q&A: live -Status: Captions added to video +Status: Now playing Duration: 19:52 -
