WEBVTT 00:00.000 --> 00:11.000 Hello everybody here at FosterM at fellow room for the lighting talks. 00:11.000 --> 00:20.240 I want to introduce to you Moon and he's talking to us about the topic status of a CGK input 00:20.240 --> 00:26.360 system in a wayland, give him a warm welcome and enjoy the talk. 00:26.360 --> 00:37.160 Hello everyone, I'm Song Jun Moon, you can just call me Moon or Octopus Edy. 00:37.160 --> 00:43.240 Today I'm going to talk about the status of CGK input system in a wayland. 00:43.240 --> 00:47.360 Have you guys any heard about the CGK? 00:47.360 --> 00:51.240 Yeah, there's like five people. 00:51.240 --> 00:57.680 So CGK or CGK, we stands for the Chinese Japanese Korean Vietnamese. 00:57.680 --> 01:04.640 The reason that this sporting or three thing is group is they use actually same characters 01:04.640 --> 01:10.080 or they're originally from the same characters. 01:10.080 --> 01:19.040 So I'm Korean by the way, this letters are pronounced as Hanta Moon Hua Kuan, but this Japanese 01:19.080 --> 01:22.680 also pronounced as Kanji Moon Ka-kuan. 01:22.680 --> 01:24.720 Kind of similar, right? 01:24.720 --> 01:32.600 But I think you guys expect it like actual whale and photocor stuff for my talk. 01:32.600 --> 01:36.960 But fortunately, it won't be like that. 01:36.960 --> 01:44.520 So my talk would be much like how the CGK viewers are suffering from how they 01:44.520 --> 01:47.720 typing their own languages. 01:47.760 --> 01:56.480 So it's much more like let's orient development of the CGK V-language input system. 01:56.480 --> 02:02.680 So for input the language itself, the East Asian language, you need input system. 02:02.680 --> 02:05.280 So what is input method? 02:05.280 --> 02:06.680 You need input method. 02:06.680 --> 02:14.760 Have you any one tried input method like 10 of them? 02:14.800 --> 02:21.320 Okay, input method is a special software for like inputting languages. 02:21.320 --> 02:26.760 So for the Latin languages such as English or French, you just need to type the 02:26.760 --> 02:28.720 languages than it will show up. 02:28.720 --> 02:34.640 But for the like this kind of characters, how are you going to type it? 02:34.640 --> 02:36.400 So there's some ways. 02:36.400 --> 02:42.800 So if you type these two, it will convert it to this or if you type these four words, 02:42.840 --> 02:46.320 then it will convert it to this letter. 02:46.320 --> 02:55.040 Or if you don't have any input method, you have to use this whole letters to make this 02:55.040 --> 02:57.040 kind of keyboard. 02:57.040 --> 03:05.600 It's like typewriter, typewriter, begging days for Chinese characters or this or Chinese 03:05.600 --> 03:07.280 keyboard. 03:07.280 --> 03:12.320 So you have to make every each piece for the each letters. 03:12.320 --> 03:16.560 So it won't be possible these days. 03:16.560 --> 03:19.960 So how to type the CGK languages? 03:19.960 --> 03:26.400 In mainland China, they use opinion or Chang Jie, in Taiwan, they use both form of four, which 03:26.400 --> 03:30.680 is string and they also use Chang Jie. 03:30.680 --> 03:33.040 In Japan, they use two ways. 03:33.040 --> 03:37.280 Sometime Romaji, sometimes Kanaba usually they use Romaji. 03:37.280 --> 03:47.360 Because Romaji is like the type of alphabet, then it will change to the Chinese characters. 03:47.360 --> 03:52.840 In South Korea, they use two ways or several ways, but most of the people use two 03:52.840 --> 03:53.840 ways. 03:53.840 --> 04:00.600 But in North Korea, I heard that they also use two ways, but in different people. 04:00.600 --> 04:05.960 In opinion, it's like, you know, Ni Hao, Ni Hao means hello in Chinese. 04:05.960 --> 04:13.400 If you want to type Ni Hao and I, H-A-O, then if you press space, you will change to 04:13.400 --> 04:16.560 the Chinese two of Chinese characters. 04:16.560 --> 04:19.320 And the further chewing, it's fast. 04:19.320 --> 04:27.240 So you might not be able to see that, but there's some like angled letters showed up, 04:27.240 --> 04:30.120 and another angled letters showed up. 04:30.120 --> 04:35.000 So those combinations will change to the one letter or two letters. 04:35.000 --> 04:39.200 Each letters has some sound. 04:39.200 --> 04:48.720 And the further Japanese, it's almost same as the Chinese version. 04:48.720 --> 04:55.280 So if you type the, you can see this, if you type the Ni and Theo, then it will change 04:55.320 --> 05:00.400 the Japanese hiragana, then it will be changed again to the kanji. 05:00.400 --> 05:03.440 That combination can be in Japanese. 05:03.440 --> 05:07.360 But for the Korean, it's pretty different. 05:07.360 --> 05:13.000 Korean letter has, it's, it's elements. 05:13.000 --> 05:15.280 It has three or two elements. 05:15.280 --> 05:20.800 So we don't have, we don't actually have to convert to some kind of Chinese characters 05:20.800 --> 05:22.520 or other characters. 05:22.520 --> 05:31.280 So it's like the typing English letters, but it will mix up and make into one letters. 05:31.280 --> 05:37.000 To understand this deeply, let's try and learn Korean characters in two minutes. 05:37.000 --> 05:41.000 So this character is pronounced as Han. 05:41.000 --> 05:42.760 Can you pronounce Han? 05:42.760 --> 05:43.760 Yeah. 05:43.760 --> 05:52.120 So the, that one sound like h, blue one sound like a and the black one sounds um. 05:52.120 --> 05:58.120 So Han Han. 05:58.120 --> 06:05.720 So as I said, Korean characters are combination of three or two elements. 06:05.720 --> 06:10.440 So three or two elements. 06:10.760 --> 06:15.520 So this two are consonant and middle one is bow. 06:15.520 --> 06:22.920 So if you mix those three or two, you can pronounce every Korean characters. 06:22.920 --> 06:27.800 So we, as you can see, the first one is same as Han. 06:27.800 --> 06:35.720 So h, h, h, h, then you can, you can already type two words, ha and Han. 06:35.760 --> 06:42.240 And the further, whole, you just change the R to O. 06:42.240 --> 06:46.680 So h, and the O is combined, then it becomes whole. 06:46.680 --> 06:56.880 And if you put one word more, one character more, h, then it will change to the h, or h. 06:56.880 --> 07:05.680 Then if you change the first letter instead of h, if you change the g, then it becomes go. 07:06.000 --> 07:13.960 You can check the, how the Korean keywords are looked like. 07:13.960 --> 07:19.480 It's almost same as the Korean keywords, but except these two keys is right one is for 07:19.480 --> 07:24.720 the change the mode for the English mode and Korean mode. 07:24.720 --> 07:30.960 And left one is for the type the Chinese word, but let's not talk about this. 07:31.000 --> 07:34.640 And it's starting getting messed up. 07:34.640 --> 07:37.560 It's a Japanese keyboard. 07:37.560 --> 07:41.120 Now they have to use the one to three, four, five, six, seven, and nine, ten. 07:41.120 --> 07:47.920 And the other keys to and the they have to change the like, they have three lettering. 07:47.920 --> 07:52.560 The writing system, so they have to change mode again and again. 07:52.560 --> 07:55.280 So it's quite complicated. 07:55.320 --> 08:01.560 And last one is the thing they use in China or Taiwan. 08:01.560 --> 08:07.520 So it's this green one and blue one, that one has own systems. 08:07.520 --> 08:12.400 So they can type their own language in three ways. 08:12.400 --> 08:14.600 But they don't have any converting mode. 08:14.600 --> 08:23.160 So they have to press like shift space to change the English mode or Chinese mode. 08:23.160 --> 08:28.880 So let's really talk about the way land stuff. 08:28.880 --> 08:37.080 For the way land, if you see these A's or clients and the this middle one is compositors, 08:37.080 --> 08:42.960 compositor and clients talk with the text input protocols and the compositor and 08:42.960 --> 08:46.320 input method talk with the input method protocols. 08:46.320 --> 08:57.320 So if we see how the actual protocols are implemented each software, it's kind of complicated. 08:57.320 --> 09:05.920 So if you see this FC ITF is pronounced as fine text and the I was these two are 09:05.920 --> 09:07.080 input method. 09:07.080 --> 09:15.200 So you need these two input things and then as you can see this Western and WL roots and 09:15.240 --> 09:23.200 mooder came in, these are compositors, this make the window system. 09:23.200 --> 09:30.320 So as you can see if the fight takes support that we want and we too. 09:30.320 --> 09:40.200 If you want to type some Chinese word Korean or Japanese, you also have to implement this 09:40.200 --> 09:41.200 protocol. 09:41.200 --> 09:43.200 So it has to be matched. 09:43.200 --> 09:47.960 So as you can see on the chromium side, there's no V3. 09:47.960 --> 09:55.400 So if you say WL roots only have V3, so you cannot type any Chinese word Korean 09:55.400 --> 10:04.600 characters, but someone recently implemented that luckily. 10:04.600 --> 10:11.360 So does it actually like input method or input is working at the way land? 10:11.360 --> 10:17.440 Yes, but it has some bugs. 10:17.440 --> 10:25.040 So let's just see. 10:25.040 --> 10:34.200 As you can see, the letters should be just there, but if you click other text field, it just 10:34.200 --> 10:35.320 moves. 10:35.320 --> 10:45.640 This is the box only Korean input method has, but not on the Chinese or Japanese method. 10:45.640 --> 10:52.040 It's been a painful Korean users for like 20 years. 10:52.040 --> 10:56.200 So there's a lot of issues related to the Korean input. 10:56.200 --> 11:01.960 It's actually written in Korean, but I translate it with the translator. 11:01.960 --> 11:10.280 So like this chord is not working of course and the Minecraft Korean input is not working 11:10.280 --> 11:14.720 and the ever note is not working. 11:14.720 --> 11:22.720 So if you want to check out if you want to fix something, you can check this repository. 11:22.720 --> 11:25.960 So why this kind of things are not fixed yet? 11:26.000 --> 11:35.000 So for the most important thing is, there's no almost no Korean Chinese Japanese users. 11:35.000 --> 11:40.760 There's some Chinese users, but for the Korean users, there's almost no users. 11:40.760 --> 11:47.480 And that's why there's no bug reports and there's no explanations and there's no developers 11:47.480 --> 11:51.160 who understand about their own languages. 11:51.160 --> 11:56.200 And as I said, Korean input is different with the Chinese and Japanese, but it's grouped 11:56.200 --> 12:04.200 into one things, so they think it's same system, so we have our own bugs, Koreans have own 12:04.200 --> 12:05.200 bugs. 12:05.200 --> 12:13.600 That's because the pre-added or things to become it, but in Chinese and Japanese, it's 12:13.600 --> 12:18.960 pre-added should be changed to the other cultures. 12:19.000 --> 12:26.640 And as I showed you before, when you click other things that characters are moved or just 12:26.640 --> 12:35.520 gone, and for the last thing, current protocols have some limitations such as when you 12:35.520 --> 12:42.680 type something, the candidates for the convertible characters should be showed up on the 12:42.680 --> 12:51.960 public window, but those windows are not that implemented well, so there's some problems 12:51.960 --> 12:55.360 with that. 12:55.360 --> 12:55.720 Thank you.
