+00:00:00.000 --> 00:00:04.456
+Okay. Good afternoon, morning or evening,
+
+00:00:04.457 --> 00:00:06.519
+whatever it is in your airtime zone.
+
+00:00:06.520 --> 00:00:10.959
+I'm Pedro Aranda and I'm going to be talking about
+
+00:00:10.960 --> 00:00:12.959
+what I've been doing
+
+00:00:12.960 --> 00:00:16.999
+with the latest backend in Org Mode
+
+00:00:17.000 --> 00:00:24.719
+and the different Sorry, and the way it treats fonts.
+
+00:00:24.720 --> 00:00:28.279
+Just a couple of words before
+
+00:00:28.280 --> 00:00:30.359
+I am going to go through motivation,
+
+00:00:30.360 --> 00:00:35.279
+the evolution and get you an idea of what you can get
+
+00:00:35.280 --> 00:00:38.079
+from the feature branch that I have started
+
+00:00:38.080 --> 00:00:41.399
+and give a couple of demos.
+
+00:00:41.400 --> 00:00:47.779
+actually my motivation is I was using ox-latex currently
+
+00:00:47.780 --> 00:00:51.439
+and b and ox-beamer for as a foundation for my activities
+
+00:00:51.440 --> 00:00:54.399
+mainly for lecture notes and lecture slides
+
+00:00:54.400 --> 00:01:01.359
+so i came from pure latex and beamers
+
+00:01:01.360 --> 00:01:04.519
+and for me the real cool use case
+
+00:01:04.520 --> 00:01:05.959
+or I would say this was
+
+00:01:05.960 --> 00:01:07.959
+the killer use case for me was
+
+00:01:07.960 --> 00:01:09.239
+I have a programming lecture
+
+00:01:09.240 --> 00:01:12.199
+which is sort of a Python 101
+
+00:01:12.200 --> 00:01:14.199
+and when I'm live in the lecture
+
+00:01:14.200 --> 00:01:18.279
+I can go and if the pupils ask me I can modify code,
+
+00:01:18.280 --> 00:01:21.079
+show modified code and results on the fly
+
+00:01:21.080 --> 00:01:25.119
+and that's something that really impresses the kids
+
+00:01:25.120 --> 00:01:30.159
+and makes them understand what we are talking about.
+
+00:01:30.160 --> 00:01:34.399
+From my pro-subjective point of view, in some,
+
+00:01:34.400 --> 00:01:38.159
+mainly in ox-beamer, some of the things that I was missing
+
+00:01:38.160 --> 00:01:41.879
+is that emojis would really break the monotony
+
+00:01:41.880 --> 00:01:47.679
+and I missed the support for emojis and stock Beamer themes.
+
+00:01:47.680 --> 00:01:52.159
+And some fonts I also found were suboptimal
+
+00:01:52.160 --> 00:01:56.639
+or difficult to adapt in case they need an adaptation.
+
+00:01:56.640 --> 00:02:01.799
+So, for example, people who need special fonts
+
+00:02:01.800 --> 00:02:05.799
+because of their special capabilities,
+
+00:02:05.800 --> 00:02:11.159
+it's difficult to get those fonts from the stock themes
+
+00:02:11.160 --> 00:02:17.359
+and from the stock font implementations you have there.
+
+00:02:17.360 --> 00:02:19.399
+So, requirements on mice
+
+00:02:19.400 --> 00:02:21.479
+from the Emacs site to do this is none,
+
+00:02:21.480 --> 00:02:24.999
+because basically, okay, the only thing I want
+
+00:02:25.000 --> 00:02:27.159
+is to work on a vanilla Emacs,
+
+00:02:27.160 --> 00:02:28.399
+which is more or less recent,
+
+00:02:28.400 --> 00:02:30.119
+because yes, I'm a bit of a freak
+
+00:02:30.120 --> 00:02:32.479
+and I compile it every two, three,
+
+00:02:32.480 --> 00:02:36.839
+I get it from master and compile it every two, three days.
+
+00:02:36.840 --> 00:02:40.599
+And Yahoo, I had to change to Neumark,
+
+00:02:40.600 --> 00:02:47.359
+and I'm able now to get my vanilla Neumarks within four.
+
+00:02:47.360 --> 00:02:53.359
+So that was a big accomplishment in these last days.
+
+00:02:53.360 --> 00:02:55.119
+What is the evolution?
+
+00:02:55.120 --> 00:03:00.719
+I mean my personal evolution and my take of xLatex
+
+00:03:00.720 --> 00:03:05.919
+was I put everything in a in a latex file
+
+00:03:05.920 --> 00:03:09.959
+and I input it through the latex shader and that's it.
+
+00:03:09.960 --> 00:03:12.319
+But that was not very beginner friendly
+
+00:03:12.320 --> 00:03:15.719
+and once I had some people interested in this,
+
+00:03:15.720 --> 00:03:19.159
+oh wow I can modify the code on the fly
+
+00:03:19.160 --> 00:03:21.119
+and see the results on the fly,
+
+00:03:21.120 --> 00:03:26.719
+it was more difficult for them to give it a go.
+
+00:03:26.720 --> 00:03:32.359
+So I just, because they,
+
+00:03:32.360 --> 00:03:36.919
+there are people who have not that big,
+
+00:03:36.920 --> 00:03:41.159
+that much experience with LaTeX
+
+00:03:41.160 --> 00:03:44.919
+and It can even be a bridge to introduce people into latex.
+
+00:03:44.920 --> 00:03:48.959
+So, in any case, it was not very beginner-friendly
+
+00:03:48.960 --> 00:03:52.799
+and I had complaints on that.
+
+00:03:52.800 --> 00:03:57.159
+So, what I think was, we can do better.
+
+00:03:57.160 --> 00:04:00.399
+My first attempt was something that was completely neutral
+
+00:04:00.400 --> 00:04:02.879
+to Babel or Polyglosia.
+
+00:04:02.880 --> 00:04:06.199
+and it was made basically for font Lattesch
+
+00:04:06.200 --> 00:04:08.839
+although some of the things can for rural Lattesch
+
+00:04:08.840 --> 00:04:14.279
+and some of the things can also be used with the latest.
+
+00:04:14.280 --> 00:04:16.519
+So overriding template fonts
+
+00:04:16.520 --> 00:04:21.279
+and taking into account pullback fonts
+
+00:04:21.280 --> 00:04:23.839
+was something that I learned uh uh
+
+00:04:23.840 --> 00:04:27.959
+when we started this conversation
+
+00:04:27.960 --> 00:04:29.839
+and the only problem with this
+
+00:04:29.840 --> 00:04:34.799
+is that fallback fonts only work for latex
+
+00:04:34.800 --> 00:04:40.679
+and because uh because it doesn't support them
+
+00:04:40.680 --> 00:04:42.439
+actually for fallback points is a lua feature
+
+00:04:42.440 --> 00:04:45.319
+There was already something in the list
+
+00:04:45.320 --> 00:04:48.399
+regarding script detection which helped me a lot.
+
+00:04:48.400 --> 00:04:52.399
+So big recognition to Romano Lafias for that
+
+00:04:52.400 --> 00:04:57.679
+and for his publishing the algorithm or the script
+
+00:04:57.680 --> 00:05:04.399
+and the in the org mode mailing list.
+
+00:05:04.400 --> 00:05:11.319
+And then came my sort of little nightmare,
+
+00:05:11.320 --> 00:05:13.879
+which was when we started talking
+
+00:05:13.880 --> 00:05:17.359
+about internationalization or localization.
+
+00:05:17.360 --> 00:05:21.599
+Looking back, I have a very strange feeling
+
+00:05:21.600 --> 00:05:22.919
+about a blurring target there.
+
+00:05:22.920 --> 00:05:29.679
+Because the reality being very, very frank, did I need it?
+
+00:05:29.680 --> 00:05:34.919
+Really no, because I just needed
+
+00:05:34.920 --> 00:05:39.999
+to add Spanish with Babel and that was it.
+
+00:05:40.000 --> 00:05:43.199
+Well actually for me it still is
+
+00:05:43.200 --> 00:05:46.519
+and you can put the British, German or Italian
+
+00:05:46.520 --> 00:05:48.359
+it continues to be true for me
+
+00:05:48.360 --> 00:05:51.839
+so I had personally I had little interest in doing that
+
+00:05:51.840 --> 00:05:55.319
+but I took it as a challenge
+
+00:05:55.320 --> 00:06:02.479
+which has shown to be really tough.
+
+00:06:02.480 --> 00:06:05.799
+What do you get from the feature branch? The feature branch
+
+00:06:05.800 --> 00:06:08.999
+adds font management for font spec,
+
+00:06:09.000 --> 00:06:10.839
+which is not strictly needed
+
+00:06:10.840 --> 00:06:16.079
+when you are on Latin, Cyrillic, and Greek scripts
+
+00:06:16.080 --> 00:06:20.599
+as long as the fonts in your template support them.
+
+00:06:20.600 --> 00:06:28.799
+But again, it's a nice way to get better support here.
+
+00:06:28.800 --> 00:06:33.039
+You don't need it if you're happy with the fonts you get
+
+00:06:33.040 --> 00:06:38.439
+from the templates that you use both for Beamer
+
+00:06:38.440 --> 00:06:40.359
+and the document classes in LaTeX.
+
+00:06:40.360 --> 00:06:43.639
+If you don't want to use alternative fonts,
+
+00:06:43.640 --> 00:06:47.999
+you don't need it, but you would need it.
+
+00:06:48.000 --> 00:06:50.639
+Of course, if you don't want things like,
+
+00:06:50.640 --> 00:06:55.719
+for example, emojis or need emojis,
+
+00:06:55.720 --> 00:06:59.359
+you really don't need forward fonts.
+
+00:06:59.360 --> 00:07:03.959
+So my idea is that the next thing that you can add
+
+00:07:03.960 --> 00:07:07.319
+is Babel and Polyglos here
+
+00:07:07.320 --> 00:07:13.079
+for enhanced localization and multilingual documents there.
+
+00:07:13.080 --> 00:07:17.799
+And at the end, my vision was that the keywords involved
+
+00:07:17.800 --> 00:07:19.799
+would be language, the main language.
+
+00:07:19.800 --> 00:07:23.039
+And then a nice idea from Ihor
+
+00:07:23.040 --> 00:07:27.199
+was to put all the secondary languages there too.
+
+00:07:27.200 --> 00:07:30.559
+Then specify the LaTeX compiler
+
+00:07:30.560 --> 00:07:32.639
+and then what I've added is a keyword
+
+00:07:32.640 --> 00:07:34.279
+which is LaTeX Montylang
+
+00:07:34.280 --> 00:07:37.879
+which can be fontspec or babel or polyglossia
+
+00:07:37.880 --> 00:07:40.319
+for localized documents.
+
+00:07:40.320 --> 00:07:45.359
+By default, this thing is nil and when it is nil,
+
+00:07:45.360 --> 00:07:51.719
+you get the behavior from OrgBug
+
+00:07:51.720 --> 00:07:56.559
+that you already are used to if you don't want to switch.
+
+00:07:56.560 --> 00:08:00.559
+and I was there and I was really
+
+00:08:00.560 --> 00:08:03.479
+was chirped into the conversation
+
+00:08:03.480 --> 00:08:06.799
+and I'm really helpful and a big thanks to him
+
+00:08:06.800 --> 00:08:09.199
+because he also had a an easy idea
+
+00:08:09.200 --> 00:08:13.079
+to support Chinese and Japanese documents
+
+00:08:13.080 --> 00:08:17.239
+so that the only thing that you need is to add the language
+
+00:08:17.240 --> 00:08:19.879
+that you're going to write your document in
+
+00:08:19.880 --> 00:08:23.639
+very very big thank you for that
+
+00:08:23.640 --> 00:08:25.399
+because that was really a challenge
+
+00:08:25.400 --> 00:08:29.279
+not being able to decipher
+
+00:08:29.280 --> 00:08:32.639
+what I was what I was coding there
+
+00:08:32.640 --> 00:08:34.439
+in terms of I have a document
+
+00:08:34.440 --> 00:08:37.519
+I copy and paste it from some place
+
+00:08:37.520 --> 00:08:40.039
+and from there I get my answer I get my my pdf
+
+00:08:40.040 --> 00:08:47.279
+and I compare whether it is correct or not
+
+00:08:47.280 --> 00:08:50.239
+So what is behind the scenes?
+
+00:08:50.240 --> 00:08:52.959
+I've always suggested that in order
+
+00:08:52.960 --> 00:08:55.239
+to use the feature branch efficiently
+
+00:08:55.240 --> 00:08:59.919
+you create a file with the default values
+
+00:08:59.920 --> 00:09:02.439
+you need for your variables
+
+00:09:02.440 --> 00:09:06.199
+and that's the this famous.locals.el files.
+
+00:09:06.200 --> 00:09:10.239
+What I do is I have a generic one
+
+00:09:10.240 --> 00:09:12.079
+in my home documents directory
+
+00:09:12.080 --> 00:09:16.599
+and this is used for all the org documents
+
+00:09:16.600 --> 00:09:20.559
+that are in subdirectories from there.
+
+00:09:20.560 --> 00:09:24.039
+Why? Because normally you will not be
+
+00:09:24.040 --> 00:09:26.599
+changing your fonts that often.
+
+00:09:26.600 --> 00:09:29.599
+and if you need you can always go
+
+00:09:29.600 --> 00:09:33.479
+and have your configuration locally.
+
+00:09:33.480 --> 00:09:38.639
+So it's this point where I'm collecting
+
+00:09:38.640 --> 00:09:40.759
+my phone configuration and
+
+00:09:40.760 --> 00:09:47.519
+For me, this gives me a very, very nice quick start
+
+00:09:47.520 --> 00:09:49.639
+for new documents and presentations.
+
+00:09:49.640 --> 00:09:54.639
+And there you can even configure a lot of compiler
+
+00:09:54.640 --> 00:09:57.919
+and font language management too,
+
+00:09:57.920 --> 00:10:00.919
+so you have everything in a file.
+
+00:10:00.920 --> 00:10:04.759
+And the other nice thing for that
+
+00:10:04.760 --> 00:10:08.479
+is that you can also include that in a subdirectory.
+
+00:10:08.480 --> 00:10:13.199
+And if this subdirectory is something that you're sharing
+
+00:10:13.200 --> 00:10:14.479
+in a project with other people,
+
+00:10:14.480 --> 00:10:17.759
+you are already configuring the, say,
+
+00:10:17.760 --> 00:10:23.559
+quote, unquote, corporate look and feel for your documents
+
+00:10:23.560 --> 00:10:26.079
+in that project for everyone
+
+00:10:26.080 --> 00:10:28.919
+and no one else has to care about
+
+00:10:28.920 --> 00:10:35.119
+how this document has to be configured.
+
+00:10:35.120 --> 00:10:38.679
+One of the things that I really like in this approach
+
+00:10:38.680 --> 00:10:40.439
+is that it is a grow-as-you-go.
+
+00:10:40.440 --> 00:10:44.079
+So, for example, you can start with something like that,
+
+00:10:44.080 --> 00:10:48.439
+which is I have my fonts, my basic fonts for main,
+
+00:10:48.440 --> 00:10:51.479
+which is the Serif font, for sans,
+
+00:10:51.480 --> 00:10:54.079
+which is the Sans Serif font, for maths,
+
+00:10:54.080 --> 00:10:58.639
+and for the mono, with some features like to make them scale.
+
+00:10:58.640 --> 00:11:02.679
+This is something that is uh provided by you
+
+00:11:02.680 --> 00:11:05.359
+through the font spec package
+
+00:11:05.360 --> 00:11:08.959
+and you're happy with it and you work with it
+
+00:11:08.960 --> 00:11:11.919
+and given a in a given moment
+
+00:11:11.920 --> 00:11:14.439
+you go and you have your own problems
+
+00:11:14.440 --> 00:11:16.599
+and or your own challenge
+
+00:11:16.600 --> 00:11:20.279
+and you need to have for example emojis for one of the fonts
+
+00:11:20.280 --> 00:11:24.959
+and what you do is in this case you just add the emojis
+
+00:11:24.960 --> 00:11:31.239
+as a fallback font in in the font that where you want to replace this
+
+00:11:31.240 --> 00:11:36.119
+is this is what i'm doing right now for this presentation and you will see
+
+00:11:36.120 --> 00:11:39.119
+You can always, as I've said,
+
+00:11:39.120 --> 00:11:42.359
+you can always have your dear locals
+
+00:11:42.360 --> 00:11:46.319
+and you can copy that into a working directory
+
+00:11:46.320 --> 00:11:49.439
+which needs special adaptations or has special needs
+
+00:11:49.440 --> 00:11:54.119
+and from there you have that directory
+
+00:11:54.120 --> 00:11:59.079
+with your modified or customized their local study l file
+
+00:11:59.080 --> 00:12:05.439
+so font spec is normally enough
+
+00:12:05.440 --> 00:12:09.999
+but sometimes you can't control all the fonts
+
+00:12:10.000 --> 00:12:15.479
+with font spec only so and there you have a polyglot here
+
+00:12:15.480 --> 00:12:19.319
+and babel coming to your help
+
+00:12:19.320 --> 00:12:21.359
+this may also be the case
+
+00:12:21.360 --> 00:12:25.879
+that you are working in an intended language
+
+00:12:25.880 --> 00:12:28.959
+i don't know which but an intended language and you found
+
+00:12:28.960 --> 00:12:31.279
+and you wanted to see how that was configured
+
+00:12:31.280 --> 00:12:34.999
+and you found the latest example
+
+00:12:35.000 --> 00:12:38.639
+that used Babel or Polyglossia.
+
+00:12:38.640 --> 00:12:42.559
+The exporter provides you three variables
+
+00:12:42.560 --> 00:12:48.679
+to configure both font spec, Polyglossia and Babel.
+
+00:12:48.680 --> 00:12:56.799
+So just as an example of how I picture this is,
+
+00:12:56.800 --> 00:12:59.359
+uh, you find it in the internet,
+
+00:12:59.360 --> 00:13:01.679
+something like that, uh, something like this,
+
+00:13:01.680 --> 00:13:05.599
+because you have your document and you need tie.
+
+00:13:05.600 --> 00:13:09.999
+So, and I found an example in the internet
+
+00:13:10.000 --> 00:13:12.679
+that tells me that I'm going to be using
+
+00:13:12.680 --> 00:13:15.079
+Babel main is going to be English.
+
+00:13:15.080 --> 00:13:17.919
+And I'm also going to have a tie.
+
+00:13:17.920 --> 00:13:22.879
+and then they tell me that for english
+
+00:13:22.880 --> 00:13:26.639
+i'm going to be using noto serif for the main
+
+00:13:26.640 --> 00:13:31.759
+for the main of the serif font noto sans for the sans font
+
+00:13:31.760 --> 00:13:35.799
+and then when i'm writing things in thai
+
+00:13:35.800 --> 00:13:40.119
+i'm going to be using noto serif thai and noto sans thai
+
+00:13:40.120 --> 00:13:42.399
+That's what I see in the internet.
+
+00:13:42.400 --> 00:13:47.159
+So what you can always do, what you would do in this case,
+
+00:13:47.160 --> 00:13:54.279
+is I'm going to get and map the font configurations
+
+00:13:54.280 --> 00:13:59.239
+from the latest into this variable.
+
+00:13:59.240 --> 00:14:03.479
+Things that you have to take into account here
+
+00:14:03.480 --> 00:14:05.919
+is, for example, the language.
+
+00:14:05.920 --> 00:14:11.919
+The language here is Thai. You have the language
+
+00:14:11.920 --> 00:14:16.759
+that you're intending this font for is Thai.
+
+00:14:16.760 --> 00:14:21.279
+So this appears here. In case you don't have any language,
+
+00:14:21.280 --> 00:14:24.799
+like in the first two lines,
+
+00:14:24.800 --> 00:14:27.239
+you just say that the language is nil,
+
+00:14:27.240 --> 00:14:31.439
+which is the language for the default language.
+
+00:14:31.440 --> 00:14:34.799
+The other thing is in my example,
+
+00:14:34.800 --> 00:14:40.039
+in this example that I found in the internet,
+
+00:14:40.040 --> 00:14:46.319
+I have my properties for the fonts in this part in Latex
+
+00:14:46.320 --> 00:14:52.239
+and I put them as properties here.
+
+00:14:52.240 --> 00:14:55.079
+That's the whole idea behind the feature branch.
+
+00:14:55.080 --> 00:15:03.119
+The Babel provide part is also integrated
+
+00:15:03.120 --> 00:15:10.119
+from the Org header, mainly from the language line.
+
+00:15:10.120 --> 00:15:14.639
+We have a variable in case you need to tweak it,
+
+00:15:14.640 --> 00:15:21.079
+but normally the defaults provided by Org are good enough.
+
+00:15:21.080 --> 00:15:27.679
+So what is the rationale behind my take at Latex Fonts Management?
+
+00:15:27.680 --> 00:15:31.359
+And that's something that might be something very personal.
+
+00:15:31.360 --> 00:15:33.759
+When am I using FontSpec?
+
+00:15:33.760 --> 00:15:37.239
+I'm using FontSpec when I'm with Lua or Zlatex
+
+00:15:37.240 --> 00:15:40.279
+and I want fonts that are different
+
+00:15:40.280 --> 00:15:42.439
+from those specified in the Latex class.
+
+00:15:42.440 --> 00:15:49.279
+That's point number one. I will also go for font spec
+
+00:15:49.280 --> 00:15:52.599
+when I need to support scripts,
+
+00:15:52.600 --> 00:15:54.559
+but I'm missing in the fonts I use,
+
+00:15:54.560 --> 00:15:59.479
+and I can use fallback fonts for that. I have two.
+
+00:15:59.480 --> 00:16:05.239
+The only limitation I have here is the following.
+
+00:16:05.240 --> 00:16:09.039
+All languages must be left to right.
+
+00:16:09.040 --> 00:16:12.799
+And if you don't say anything at all,
+
+00:16:12.800 --> 00:16:16.519
+the LATIC backend assumes that you want the dates,
+
+00:16:16.520 --> 00:16:19.159
+standard names for the abstract and so on
+
+00:16:19.160 --> 00:16:21.039
+in American English. if you're using them.
+
+00:16:21.040 --> 00:16:25.439
+In many cases, you're not using any sort of
+
+00:16:25.440 --> 00:16:32.319
+abstract table of contents and so on
+
+00:16:32.320 --> 00:16:37.239
+and you don't need that.
+
+00:16:37.240 --> 00:16:44.599
+The important thing is maybe date management.
+
+00:16:44.600 --> 00:16:50.399
+If you need dates, headings
+
+00:16:50.400 --> 00:16:56.919
+or anything in any other language or locale,
+
+00:16:56.920 --> 00:17:06.599
+then yes, then you need to use Babel or Polyglosia.
+
+00:17:06.600 --> 00:17:12.079
+Choice, Depends. Can use poly loss here,
+
+00:17:12.080 --> 00:17:15.639
+or you can use Babel, whatever you want.
+
+00:17:15.640 --> 00:17:20.079
+Also, in some cases, it will depend
+
+00:17:20.080 --> 00:17:21.839
+if you've been researching a bit
+
+00:17:21.840 --> 00:17:24.119
+of how this is done with pure latest,
+
+00:17:24.120 --> 00:17:25.999
+it will be also depending on, uh,
+
+00:17:26.000 --> 00:17:28.919
+on the examples that you get.
+
+00:17:28.920 --> 00:17:35.719
+So, what can you, when you are using
+
+00:17:35.720 --> 00:17:41.639
+Babel or Polygross here, what do you have?
+
+00:17:41.640 --> 00:17:46.239
+You have your dates, your headings, and so on.
+
+00:17:46.240 --> 00:17:48.279
+You might need to control the text
+
+00:17:48.280 --> 00:17:51.239
+in the sense that what passage
+
+00:17:51.240 --> 00:17:53.479
+is written in what language.
+
+00:17:53.480 --> 00:17:58.119
+For example, for things like hyphenation
+
+00:17:58.120 --> 00:18:01.919
+and some ways of writing the hyphens in a
+
+00:18:01.920 --> 00:18:12.039
+and direct speech and things like that.
+
+00:18:12.040 --> 00:18:17.359
+And the other place where you need
+
+00:18:17.360 --> 00:18:19.199
+other Babel or polyglots here,
+
+00:18:19.200 --> 00:18:24.559
+and you will see that because all examples
+
+00:18:24.560 --> 00:18:26.839
+that you can get for later in this case
+
+00:18:26.840 --> 00:18:30.679
+is when you have a language
+
+00:18:30.680 --> 00:18:38.199
+that uses right to left alignment
+
+00:18:38.200 --> 00:18:40.439
+like Arabic, Hebrew and others.
+
+00:18:40.440 --> 00:18:45.359
+So One note of, I would say, care is you always use the,
+
+00:18:45.360 --> 00:18:46.479
+if you use Unicode fonts
+
+00:18:46.480 --> 00:18:49.359
+that includes the scripts as you need,
+
+00:18:49.360 --> 00:18:51.759
+you will have done, that will be a great leap for you
+
+00:18:51.760 --> 00:18:53.759
+because that simplifies the configuration a lot.
+
+00:18:53.760 --> 00:18:55.359
+Now a couple of demos.
+
+00:18:55.360 --> 00:19:01.079
+I don't know if you've noticed
+
+00:19:01.080 --> 00:19:03.359
+first demo is that I'm using.
+
+00:19:03.360 --> 00:19:05.119
+fonts but are not the official fonts
+
+00:19:05.120 --> 00:19:06.399
+in this Beamer template
+
+00:19:06.400 --> 00:19:07.959
+which is by the way Boadilla.
+
+00:19:07.960 --> 00:19:10.519
+This would be the first thing
+
+00:19:10.520 --> 00:19:14.079
+so I've been using other fonts
+
+00:19:14.080 --> 00:19:17.639
+and they are at least from what I get in class
+
+00:19:17.640 --> 00:19:20.439
+they are more readable than the official
+
+00:19:20.440 --> 00:19:22.439
+than the default fonts in Poliglossi
+
+00:19:22.440 --> 00:19:24.439
+that you get in Babel for the Boadilla theme.
+
+00:19:24.440 --> 00:19:25.959
+Another thing is what I've told you,
+
+00:19:25.960 --> 00:19:27.559
+I have my own things like emojis.
+
+00:19:27.560 --> 00:19:29.799
+Now, if you allow me for a second,
+
+00:19:29.800 --> 00:19:38.399
+I'm going to switch to the Emacs
+
+00:19:38.400 --> 00:19:40.279
+which is running behind the scenes to show you what.
+
+00:19:40.280 --> 00:19:45.719
+Okay, fine. So, this is the presentation.
+
+00:19:45.720 --> 00:19:47.879
+that I have here, and as you see,
+
+00:19:47.880 --> 00:19:50.959
+I'm using Lua Latex and just one spec.
+
+00:19:50.960 --> 00:19:59.479
+given I don't know why I would I would need this
+
+00:19:59.480 --> 00:20:01.079
+this is an English presentation
+
+00:20:01.080 --> 00:20:03.039
+but just to show you what you can do
+
+00:20:03.040 --> 00:20:09.359
+if I go back here and I go to the beginning of the presentation
+
+00:20:09.360 --> 00:20:13.159
+and now what I don't think you're showing anything oh thank you
+
+00:20:13.160 --> 00:20:21.399
+Okay, this is the presentation, right?
+
+00:20:21.400 --> 00:20:33.559
+So what I'm going to do is I'm going to go back
+
+00:20:33.560 --> 00:20:35.839
+and I'm going to show the full screen.
+
+00:20:35.840 --> 00:20:37.199
+And in this full screen,
+
+00:20:37.200 --> 00:20:41.919
+you see the presentation on one side
+
+00:20:41.920 --> 00:20:46.079
+and you see Emacs on the other side. Oh, still nothing.
+
+00:20:46.080 --> 00:20:50.279
+Yeah, we're not seeing your screen at the moment, sorry.
+
+00:20:50.280 --> 00:20:54.079
+Oh, thank you. Thank you for that.
+
+00:20:54.080 --> 00:20:59.959
+Now it's starting to come. Okay. Yay! Fine.
+
+00:20:59.960 --> 00:21:03.479
+So this presentation, I've done it with Lua Latex,
+
+00:21:03.480 --> 00:21:05.839
+and what I add here is font spec and English language.
+
+00:21:05.840 --> 00:21:10.279
+Just to show you, but with the same configuration,
+
+00:21:10.280 --> 00:21:14.279
+with the same font spec configuration,
+
+00:21:14.280 --> 00:21:15.439
+but adding Polyglossia.
+
+00:21:15.440 --> 00:21:23.159
+I just have enough with adding polygons here
+
+00:21:23.160 --> 00:21:28.799
+with the Spanish language to get my dates correctly
+
+00:21:28.800 --> 00:21:32.559
+and this is something I'm going to see the date in English
+
+00:21:32.560 --> 00:21:46.719
+and if I now go and recompile it in a couple of seconds
+
+00:21:46.720 --> 00:21:48.999
+you will see that the data is in Spanish.
+
+00:21:49.000 --> 00:21:53.879
+We are using the same Which I can show by the way.
+
+00:21:53.880 --> 00:21:58.079
+I see just by adding polyglyphs here.
+
+00:21:58.080 --> 00:21:59.439
+I can get my dates in Spanish.
+
+00:21:59.440 --> 00:22:09.559
+What I have included the the locals in the.
+
+00:22:09.560 --> 00:22:14.999
+In this in this lines, but just to discuss it a bit more.
+
+00:22:15.000 --> 00:22:19.439
+I have it for all the presentations.
+
+00:22:19.440 --> 00:22:24.319
+I think it was here. No. For the demo.
+
+00:22:24.320 --> 00:22:27.719
+For the presentations I use for MX conferences.
+
+00:22:27.720 --> 00:22:31.119
+I have it and it's something like this.
+
+00:22:31.120 --> 00:22:37.359
+actually you don't need a fallback
+
+00:22:37.360 --> 00:22:39.439
+for for the main font here
+
+00:22:39.440 --> 00:22:44.239
+because the presentations are done with the sans font
+
+00:22:44.240 --> 00:22:46.559
+so the only thing that I would really need
+
+00:22:46.560 --> 00:22:48.199
+would be something like this
+
+00:22:48.200 --> 00:22:53.359
+this can be commented and the same happens here
+
+00:22:53.360 --> 00:22:56.159
+with the model this can be also commented
+
+00:22:56.160 --> 00:23:00.399
+and the only thing where I would really need
+
+00:23:00.400 --> 00:23:02.119
+a full back font is here
+
+00:23:02.120 --> 00:23:04.319
+and what this is telling me is that
+
+00:23:04.320 --> 00:23:07.079
+you have a full back for the emoji
+
+00:23:07.080 --> 00:23:09.799
+for the emoji script
+
+00:23:09.800 --> 00:23:15.399
+and you need to use the apple color emoji font with A modifier
+
+00:23:15.400 --> 00:23:18.759
+which in this case is that you need
+
+00:23:18.760 --> 00:23:21.359
+to have the half-word renderer.
+
+00:23:21.360 --> 00:23:24.599
+That's the only thing that you really need.
+
+00:23:24.600 --> 00:23:26.679
+Where do I get all these things from?
+
+00:23:26.680 --> 00:23:29.039
+All these things I get from the different parts
+
+00:23:29.040 --> 00:23:32.079
+and from different scripts in the Internet.
+
+00:23:32.080 --> 00:23:38.039
+I also have a couple of other things to show.
+
+00:23:38.040 --> 00:23:42.919
+For example, first of all, I do not need this.
+
+00:23:42.920 --> 00:23:44.749
+This is a letter that I've been writing this morning
+
+00:23:44.750 --> 00:23:55.640
+and I'm not using the full feature branches at all
+
+00:23:55.641 --> 00:23:58.119
+because I just needed a sans font
+
+00:23:58.120 --> 00:24:02.119
+and it's going to be a letter that I'm writing in.
+
+00:24:02.120 --> 00:24:06.119
+with the sans font and the only thing I need
+
+00:24:06.120 --> 00:24:09.119
+was Spanish for the date anyhow
+
+00:24:09.120 --> 00:24:14.719
+how did what was my first thing that I did
+
+00:24:14.720 --> 00:24:19.639
+with the back end back in I think it was April
+
+00:24:19.640 --> 00:24:23.079
+we had a this comes from the mailing list
+
+00:24:23.080 --> 00:24:26.759
+we had someone who had this who had this problem right
+
+00:24:26.760 --> 00:24:29.559
+and he wanted to add emojis
+
+00:24:29.560 --> 00:24:33.039
+and he had problems with the verbatim font
+
+00:24:33.040 --> 00:24:35.279
+And that's how everything got started.
+
+00:24:35.280 --> 00:24:42.599
+If you now go and I get my period
+
+00:24:42.600 --> 00:24:44.599
+of latex for that running.
+
+00:24:44.600 --> 00:24:50.559
+Well, I actually, all my latex is supported for that.
+
+00:24:50.560 --> 00:24:58.119
+And this was what I showed in one of the Emacs, Org Mode meetups.
+
+00:24:58.120 --> 00:25:00.079
+And there you see that We have the emojis.
+
+00:25:00.080 --> 00:25:06.879
+We had the fonts for the different things. We had maps.
+
+00:25:06.880 --> 00:25:13.799
+And you could even go and add scripts
+
+00:25:13.800 --> 00:25:16.319
+and little passages and different scripts.
+
+00:25:16.320 --> 00:25:22.359
+And this was done with the same principles that I want.
+
+00:25:22.360 --> 00:25:25.439
+I have my main font. I have the emojis.
+
+00:25:25.440 --> 00:25:30.559
+and I want, I have my son's phone and I have the emojis,
+
+00:25:30.560 --> 00:25:32.959
+the Han for Japanese and the Kana for Japanese,
+
+00:25:32.960 --> 00:25:36.799
+so that these characters here,
+
+00:25:36.800 --> 00:25:40.679
+both in the sons and in the serif passages
+
+00:25:40.680 --> 00:25:44.399
+are included correctly in the PDF.
+
+00:25:44.400 --> 00:25:49.999
+And a third thing of what you can do
+
+00:25:50.000 --> 00:25:53.439
+I've also shown this so this is more
+
+00:25:53.440 --> 00:25:55.799
+for people who have not seen it
+
+00:25:55.800 --> 00:26:01.399
+this is a side-by-side package a passage of
+
+00:26:01.400 --> 00:26:04.919
+well actually the beginning of the analysis by Xenophon
+
+00:26:04.920 --> 00:26:12.919
+both in in Greek and in German with some comments
+
+00:26:12.920 --> 00:26:18.679
+and if I go this is this is done with Polyglossia
+
+00:26:18.680 --> 00:26:25.279
+so if I go once again and produce
+
+00:26:25.280 --> 00:26:32.039
+the PDF for this just a second
+
+00:26:32.040 --> 00:26:41.119
+Come on. There you are. You get this.
+
+00:26:41.120 --> 00:26:46.399
+And there you see different fonts.
+
+00:26:46.400 --> 00:26:48.239
+Which fonts am I using for this?
+
+00:26:48.240 --> 00:26:51.279
+I'm using for the main font for me is Swissere.
+
+00:26:51.280 --> 00:27:01.479
+This listing is produced with Deja Vu Sansponor.
+
+00:27:01.480 --> 00:27:13.359
+And using Polyglos here, I'm able to go and define
+
+00:27:13.360 --> 00:27:15.799
+the Greek polytone for the variant,
+
+00:27:15.800 --> 00:27:18.799
+for the Serif variant with the Noto Serif font,
+
+00:27:18.800 --> 00:27:26.199
+just to differentiate it from the German text.
+
+00:27:26.200 --> 00:27:30.279
+And nice thing is that both in the German text
+
+00:27:30.280 --> 00:27:37.359
+You see for example here and with the Greek text
+
+00:27:37.360 --> 00:27:40.879
+everything is scaled to match
+
+00:27:40.880 --> 00:27:44.119
+the lower case of the main font which is free serif.
+
+00:27:44.120 --> 00:27:45.879
+So that everything looks
+
+00:27:45.880 --> 00:27:49.359
+extremely uniform and nice to read.
+
+00:27:49.360 --> 00:27:53.759
+So that's what you want to do.
+
+00:27:53.760 --> 00:27:56.519
+That's what you can do with this.
+
+00:27:56.520 --> 00:28:00.759
+Just a couple of final words on this.
+
+00:28:00.760 --> 00:28:17.519
+I want to thank once again Juan Manuel Garcia and Jim Crump
+
+00:28:17.520 --> 00:28:19.919
+for what they have shared.
+
+00:28:19.920 --> 00:28:24.079
+And I also want to thank everybody
+
+00:28:24.080 --> 00:28:26.479
+for productive contributions to the discussion.
+
+00:28:26.480 --> 00:28:32.159
+I'm saying this because I think I need a longer rest
+
+00:28:32.160 --> 00:28:34.839
+and I'm going to be leaving
+
+00:28:34.840 --> 00:28:38.559
+the feature fund untouched for a couple of months
+
+00:28:38.560 --> 00:28:41.719
+so that people can take the feature branch
+
+00:28:41.720 --> 00:28:43.519
+untouched for a couple of months.
+
+00:28:43.520 --> 00:28:47.599
+to see if people want to use it and how they want to use it
+
+00:28:47.600 --> 00:28:49.919
+and then maybe in the future we can discuss
+
+00:28:49.920 --> 00:28:52.559
+if we want to integrate it or not
+
+00:28:52.560 --> 00:28:58.839
+or if people need it and all that. Now questions, comments?
+
+00:28:58.840 --> 00:29:41.279
+I think there was one question on. Beautiful for.
+
+00:29:41.280 --> 00:29:47.119
+I think that goes beyond fonts right.
+
+00:29:47.120 --> 00:29:52.839
+Someone is asking what about how is about video
+
+00:29:52.840 --> 00:29:56.319
+mainly MP4 support on ox-latex.
+
+00:29:56.320 --> 00:29:58.799
+I started the presentations with many videos.
+
+00:29:58.800 --> 00:30:07.839
+This is something that really pushed me back using ox-latex.
+
+00:30:07.840 --> 00:30:18.799
+What I would say to this is I mean this goes beyond
+
+00:30:18.800 --> 00:30:24.319
+what we're discussing here with fonts.
+
+00:30:24.320 --> 00:30:29.319
+I would advise you to go and get the same
+
+00:30:29.320 --> 00:30:35.239
+or have the same thing that I did
+
+00:30:35.240 --> 00:30:39.119
+which was first of all try to write it in latex
+
+00:30:39.120 --> 00:30:49.599
+and then Once you have the minimal working examples,
+
+00:30:49.600 --> 00:30:53.159
+you can get the latest parts
+
+00:30:53.160 --> 00:30:58.159
+integrated into your own presentation.
+
+00:30:58.160 --> 00:31:01.319
+That's what I've been doing.
+
+00:31:01.320 --> 00:31:04.519
+By the way, I still do it, for example, not in this,
+
+00:31:04.520 --> 00:31:06.079
+but for my lectures,
+
+00:31:06.080 --> 00:31:09.119
+I have a lot of I'm using a lot of ticks
+
+00:31:09.120 --> 00:31:12.479
+to do graphs and animated graphs.
+
+00:31:12.480 --> 00:31:18.319
+And that's begin export later and export later.
+
+00:31:18.320 --> 00:31:20.159
+That's what I'm doing.
+
+00:31:20.160 --> 00:31:28.999
+Videos are generally a bit tricky because you cannot
+
+00:31:29.000 --> 00:31:35.119
+So I think there is something called PDF-PC that can,
+
+00:31:35.120 --> 00:31:37.399
+this provides a lot of cloud package
+
+00:31:37.400 --> 00:31:39.079
+where you can include videos
+
+00:31:39.080 --> 00:31:44.399
+and then they can be played through that specific program.
+
+00:31:44.400 --> 00:31:46.239
+And JavaScript embedding,
+
+00:31:46.240 --> 00:31:49.999
+that can only be done through Acrobat Reader,
+
+00:31:50.000 --> 00:31:54.519
+which is like also finicky. Sure, yes.
+
+00:31:54.520 --> 00:32:03.999
+As you said there are many things that need to be changed.
+
+00:32:04.000 --> 00:32:07.199
+But I mean it's always a thing of taking it
+
+00:32:07.200 --> 00:32:11.359
+and trying to see what you can do
+
+00:32:11.360 --> 00:32:13.319
+and what the specifics are.
+
+00:32:13.320 --> 00:32:17.079
+Maybe this can be done with Acrobat
+
+00:32:17.080 --> 00:32:23.959
+and with a couple of extra packages and who knows.
+
+00:32:23.960 --> 00:32:26.359
+And you can always keep it as as late
+
+00:32:26.360 --> 00:32:34.599
+as fragments inside Org, I think. Any other questions?
