uh + +0:00:03.679,0:00:08.000 +do you think that this package can be + +0:00:05.600,0:00:11.760 +included into emacs or + +0:00:08.000,0:00:11.760 +uh empire uh + +0:00:12.320,0:00:18.560 +i think uh it most definitely can is + +0:00:15.360,0:00:21.760 +just a matter of paperwork but + +0:00:18.560,0:00:24.480 +the reason i initially wanted to make it + +0:00:21.760,0:00:25.039 +like a central package is that so that i + +0:00:24.480,0:00:28.720 +can + +0:00:25.039,0:00:31.920 +experiment with it more + +0:00:28.720,0:00:34.320 +like have more freedom to experiment but + +0:00:31.920,0:00:35.680 +eventually i think is a good candidate + +0:00:34.320,0:00:37.920 +for inclusion into + +0:00:35.680,0:00:37.920 +core + +0:00:38.800,0:00:42.640 +and because because currently not in + +0:00:41.200,0:00:44.480 +corey mass there are a couple of + +0:00:42.640,0:00:47.840 +problems with it + +0:00:44.480,0:00:50.960 +mostly in terms of performance + +0:00:47.840,0:00:53.280 +for example like anytime we want to + +0:00:50.960,0:00:54.160 +access the text in a buffer we need to + +0:00:53.280,0:00:57.360 +make + +0:00:54.160,0:01:00.480 +a copy of the text into a string + +0:00:57.360,0:01:03.520 +and then right after reading from that + +0:01:00.480,0:01:05.280 +text we need to free it right away and + +0:01:03.520,0:01:09.040 +that results in a lot of garbage + +0:01:05.280,0:01:11.920 +collection so it would be better + +0:01:09.040,0:01:12.240 +either the treasure could be included in + +0:01:11.920,0:01:15.680 +core + +0:01:12.240,0:01:16.799 +imax or dynamic dynamic model support + +0:01:15.680,0:01:19.439 +can be + +0:01:16.799,0:01:21.920 +augmented with direct text access + +0:01:19.439,0:01:21.920 +somehow + +0:01:24.080,0:01:27.200 +so the second question is will release + +0:01:26.400,0:01:30.320 +performance + +0:01:27.200,0:01:33.040 +be more competitive with cce max + +0:01:30.320,0:01:35.520 +enough so electricity in english is more + +0:01:33.040,0:01:35.520 +attractive + +0:01:35.670,0:01:43.439 +[Music] + +0:01:38.240,0:01:45.840 +i think it's possible but uh yeah + +0:01:43.439,0:01:46.799 +not sure about the amount of effort it + +0:01:45.840,0:01:52.000 +can be + +0:01:46.799,0:01:52.000 +multi-years effort and one thing that + +0:01:52.960,0:02:00.640 +even though gce max can make uh + +0:01:56.479,0:02:00.640 +it is fast enough there's + +0:02:00.719,0:02:05.280 +there's one thing that it uh cannot have + +0:02:03.119,0:02:09.679 +which is that because it's the lisp + +0:02:05.280,0:02:12.480 +it needs the garage collector so + +0:02:09.679,0:02:14.000 +we may experiment experience some kind + +0:02:12.480,0:02:17.360 +of + +0:02:14.000,0:02:19.920 +gcc post if we use live whereas the + +0:02:17.360,0:02:24.720 +currently transistor is written in c + +0:02:19.920,0:02:24.720 +so there's no such latency + +0:02:28.400,0:02:32.400 +the next question is do you think three + +0:02:31.040,0:02:36.080 +sister would be useful + +0:02:32.400,0:02:38.319 +for all buffers i can imagine it being + +0:02:36.080,0:02:39.599 +used to keep a post ast about an arc + +0:02:38.319,0:02:42.560 +buffer + +0:02:39.599,0:02:43.920 +light off element and update it in real + +0:02:42.560,0:02:46.239 +time + +0:02:43.920,0:02:47.760 +yeah actually this is a very interesting + +0:02:46.239,0:02:50.800 +idea + +0:02:47.760,0:02:53.760 +i saw someone started + +0:02:50.800,0:02:55.120 +resistor grammar for all already i don't + +0:02:53.760,0:02:58.159 +have a link right now but + +0:02:55.120,0:03:01.040 +i can look for it + +0:02:58.159,0:03:01.680 +i'll try looking for it and put the link + +0:03:01.040,0:03:05.840 +in + +0:03:01.680,0:03:05.840 +here later + +0:03:09.599,0:03:15.519 +yeah yes someone has written here the uh + +0:03:13.280,0:03:17.040 +and the biggest problem with uh right + +0:03:15.519,0:03:20.560 +now is that it doesn't have + +0:03:17.040,0:03:20.560 +formal grammar so + +0:03:21.360,0:03:24.400 +so the effort + +0:03:22.380,0:03:27.120 +[Applause] + +0:03:24.400,0:03:28.799 +be quite big i think but but once we + +0:03:27.120,0:03:31.519 +have that because the + +0:03:28.799,0:03:33.840 +tree sitter can be run on the web as + +0:03:31.519,0:03:33.840 +well + +0:03:34.239,0:03:38.080 +we can on the web and in many other + +0:03:37.440,0:03:40.720 +places + +0:03:38.080,0:03:41.840 +if we have a grammar for a traditional + +0:03:40.720,0:03:45.680 +grammar for all + +0:03:41.840,0:03:49.680 +we can bring off more + +0:03:45.680,0:03:52.000 +like everywhere that's a very cool + +0:03:49.680,0:03:52.000 +thought + +0:03:56.000,0:04:00.480 +next one is could this be used with + +0:03:58.080,0:04:03.200 +packages like smart parents that aim to + +0:04:00.480,0:04:07.120 +bring structural editing to + +0:04:03.200,0:04:11.360 +non-s expression based languages + +0:04:07.120,0:04:14.720 +yes that is actually one of the + +0:04:11.360,0:04:17.280 +intended use cases initially + +0:04:14.720,0:04:18.880 +it's definitely possible but it's just + +0:04:17.280,0:04:29.840 +that no one has + +0:04:18.880,0:04:29.840 +only started writing the integration yet + +0:04:37.199,0:04:41.919 +and next one + +0:04:40.639,0:04:45.040 +could you show the source that was + +0:04:41.919,0:04:48.479 +matched by the parser in the debug view + +0:04:45.040,0:04:53.440 +in addition to the grammar part matched + +0:04:48.479,0:04:53.440 +uh yeah that's actually um + +0:04:54.960,0:04:59.280 +on my to-do list but i haven't had time + +0:04:57.759,0:05:02.560 +for it yet + +0:04:59.280,0:05:06.560 +so uh if you go to the treesita + +0:05:02.560,0:05:08.800 +website it also has an + +0:05:06.560,0:05:11.840 +online playground where you can input + +0:05:08.800,0:05:11.840 +the code and see the + +0:05:12.000,0:05:16.000 +parse tree in real time and it's + +0:05:14.400,0:05:19.360 +actually + +0:05:16.000,0:05:22.840 +a lot more fancy than what we have in + +0:05:19.360,0:05:25.919 +imax currently so + +0:05:22.840,0:05:27.120 +yeah i just don't have time for it yes + +0:05:25.919,0:05:30.240 +so + +0:05:27.120,0:05:30.240 +some help here would be + +0:05:30.320,0:05:41.730 +very appreciated + +0:05:38.700,0:05:41.730 +[Music] + +0:05:49.919,0:05:54.240 +the next question is will it ever be + +0:05:52.000,0:05:55.280 +possible to write resetter grammars in a + +0:05:54.240,0:05:59.520 +lisp + +0:05:55.280,0:05:59.520 +or will javascript be required + +0:06:00.560,0:06:05.280 +yeah that is already answered in the + +0:06:02.800,0:06:07.600 +part so the + +0:06:05.280,0:06:08.639 +the transcript is actually just used as + +0:06:07.600,0:06:12.160 +a sort of + +0:06:08.639,0:06:14.639 +preprocessor so the + +0:06:12.160,0:06:15.680 +python generator actually works on the + +0:06:14.639,0:06:19.280 +on a json + +0:06:15.680,0:06:20.240 +structure so uh it's definitely possible + +0:06:19.280,0:06:24.240 +to replace + +0:06:20.240,0:06:24.240 +javascript with lists for this + +0:06:29.039,0:06:32.160 +how extensive will the compatibility + +0:06:31.280,0:06:35.360 +between + +0:06:32.160,0:06:35.840 +highlighting grammars for e-max and + +0:06:35.360,0:06:41.039 +those + +0:06:35.840,0:06:41.039 +for veeam nail view + +0:06:44.560,0:06:51.680 +so so right now the + +0:06:48.720,0:06:52.000 +nail vim and emacs used a different set + +0:06:51.680,0:06:55.440 +of + +0:06:52.000,0:06:59.520 +the highlighting queries and + +0:06:55.440,0:07:03.039 +item probably uses another set of + +0:06:59.520,0:07:04.960 +patterns as well i think it makes sense + +0:07:03.039,0:07:07.680 +because + +0:07:04.960,0:07:08.479 +each editor has its own like existing + +0:07:07.680,0:07:11.919 +conventions + +0:07:08.479,0:07:15.599 +for syntax highlighting so + +0:07:11.919,0:07:18.560 +at least in the beginning i don't expect + +0:07:15.599,0:07:21.520 +there is any compatibility between + +0:07:18.560,0:07:21.520 +different editors + +0:07:21.599,0:07:26.639 +but i think in the long run it will be + +0:07:27.280,0:07:31.360 +would it better if there's some kind of + +0:07:29.520,0:07:34.880 +effort to + +0:07:31.360,0:07:37.440 +unify the at least provide the + +0:07:34.880,0:07:39.759 +most common patterns that should work + +0:07:37.440,0:07:39.759 +across + +0:07:42.840,0:07:45.840 +editors + +0:07:51.759,0:07:55.280 +next one is could there be a + +0:07:53.520,0:07:57.919 +standardized approach + +0:07:55.280,0:08:00.319 +to coding automatic refactoring in the + +0:07:57.919,0:08:00.319 +future + +0:08:01.039,0:08:04.160 +so that whichever language mode you're + +0:08:02.639,0:08:12.960 +using you could see many + +0:08:04.160,0:08:16.400 +available refactoring operations + +0:08:12.960,0:08:18.639 +i'm not sure about this because the + +0:08:16.400,0:08:18.639 +like + +0:08:19.919,0:08:23.840 +most of uh refactoring operations are + +0:08:22.240,0:08:26.960 +actually very + +0:08:23.840,0:08:28.720 +like highly specific to a language or at + +0:08:26.960,0:08:32.800 +least to class of + +0:08:28.720,0:08:32.800 +class of languages so + +0:08:33.599,0:08:40.719 +so so maybe it's not like uh one single + +0:08:37.839,0:08:41.519 +approach for all the languages but maybe + +0:08:40.719,0:08:43.760 +uh + +0:08:41.519,0:08:44.959 +one for object-oriented oriented + +0:08:43.760,0:08:49.920 +languages + +0:08:44.959,0:08:49.920 +one for lisp like language for example + +0:08:50.160,0:08:55.839 +maybe one for javascript and typestream + +0:09:02.959,0:09:07.519 +next question is uh i'm completely new + +0:09:05.360,0:09:10.160 +to trisita how do i use it + +0:09:07.519,0:09:11.519 +as an end user is there any easy example + +0:09:10.160,0:09:14.000 +config out there + +0:09:11.519,0:09:15.440 +the organizer otherwise that shows + +0:09:14.000,0:09:18.959 +standard usage + +0:09:15.440,0:09:18.959 +with whatever programming language + +0:09:18.960,0:09:23.920 +[Music] + +0:09:20.480,0:09:23.920 +yeah there's no um + +0:09:27.600,0:09:32.000 +uh actually that uh so the project has + +0:09:30.880,0:09:36.399 +the documentation + +0:09:32.000,0:09:40.720 +site but it's not very expensive yet + +0:09:36.399,0:09:44.000 +i think we need to add more examples + +0:09:40.720,0:09:44.000 +to the documentation + +0:09:48.720,0:09:53.519 +can language major mode authors start + +0:09:51.200,0:09:56.240 +taking advantage of this now + +0:09:53.519,0:09:57.279 +or is it intended to be used as a minor + +0:09:56.240,0:10:00.399 +mode + +0:09:57.279,0:10:01.600 +uh actually it's both so it's intended + +0:10:00.399,0:10:04.480 +to be used + +0:10:01.600,0:10:05.920 +as a minor mode but it's also intended + +0:10:04.480,0:10:09.839 +to + +0:10:05.920,0:10:13.519 +be depended on by the major mode + +0:10:09.839,0:10:13.920 +so basically it it wants to be a minor + +0:10:13.519,0:10:17.200 +mode + +0:10:13.920,0:10:19.839 +that is dependent on by the other + +0:10:17.200,0:10:19.839 +major modes + +0:10:21.839,0:10:29.279 +and by it here i mean the the base + +0:10:25.680,0:10:29.279 +minor mode tree system mode + +0:10:30.839,0:10:37.120 +so uh question + +0:10:34.079,0:10:40.160 +11 is it possible to use this + +0:10:37.120,0:10:43.360 +for refactoring tool + +0:10:40.160,0:10:46.720 +uh yeah but + +0:10:43.360,0:10:47.680 +um like for the kind of refactoring + +0:10:46.720,0:10:52.079 +inside uh + +0:10:47.680,0:10:52.079 +buffer it is uh + +0:10:52.640,0:10:57.040 +it's very doable right now but you need + +0:10:55.040,0:11:01.120 +to write some glue code + +0:10:57.040,0:11:04.000 +but for for the kind of more + +0:11:01.120,0:11:04.399 +extensive refactoring where you want to + +0:11:04.000,0:11:09.120 +touch + +0:11:04.399,0:11:09.120 +uh like all files in a project + +0:11:09.279,0:11:12.839 +there needs there needs to be some kind + +0:11:11.440,0:11:15.920 +of the project + +0:11:12.839,0:11:18.399 +and another project and uh + +0:11:15.920,0:11:19.200 +understanding of the language uh model + +0:11:18.399,0:11:21.120 +system + +0:11:19.200,0:11:22.560 +like how they are laid out in the file + +0:11:21.120,0:11:24.480 +system as well + +0:11:22.560,0:11:26.240 +and with that understanding that there + +0:11:24.480,0:11:29.920 +should be passing of + +0:11:26.240,0:11:30.480 +the files even files on the file system + +0:11:29.920,0:11:34.000 +that + +0:11:30.480,0:11:37.760 +are not yet loaded into emacs + +0:11:34.000,0:11:40.320 +so that sounds like something more + +0:11:37.760,0:11:40.320 +a lot more + +0:11:41.040,0:11:44.560 +a lot more extensive + +0:11:46.320,0:11:50.000 +and it probably probably sounds like + +0:11:49.519,0:11:52.160 +something + +0:11:50.000,0:11:54.560 +something like an id in uh inside your + +0:11:52.160,0:11:57.839 +max already like a replacement for + +0:11:54.560,0:11:57.839 +for lsp + +0:12:07.360,0:12:11.440 +so next question is the that pop-up mx + +0:12:10.480,0:12:14.480 +window + +0:12:11.440,0:12:14.480 +how do you get that + +0:12:15.200,0:12:20.320 +is the custom hem code i wrote a long + +0:12:18.720,0:12:24.800 +time ago + +0:12:20.320,0:12:26.480 +but but right now the best way to + +0:12:24.800,0:12:29.440 +to have something like that is probably + +0:12:26.480,0:12:33.200 +the what is written here like uh + +0:12:29.440,0:12:39.839 +ham boss frame or iv spring + +0:12:33.200,0:12:43.680 +is a lot easier now + +0:12:39.839,0:12:46.320 +is there a folding mode for tree sitter + +0:12:43.680,0:12:48.079 +nowadays there's no folding mode for + +0:12:46.320,0:12:52.000 +three sitters yet + +0:12:48.079,0:12:54.880 +but uh + +0:12:52.000,0:12:58.720 +uh but i think it would better be better + +0:12:54.880,0:12:58.720 +if it's integrated with the + +0:12:59.440,0:13:03.120 +like current currently there are + +0:13:02.079,0:13:04.880 +multiple + +0:13:03.120,0:13:07.200 +i'm not sure they're moving forward + +0:13:04.880,0:13:10.240 +there are like code folding frameworks + +0:13:07.200,0:13:12.800 +inside imax already or some the + +0:13:10.240,0:13:13.920 +code showing packages like third party + +0:13:12.800,0:13:15.680 +packaging + +0:13:13.920,0:13:17.680 +and i think it's better to integrate + +0:13:15.680,0:13:20.000 +with these mods + +0:13:17.680,0:13:22.560 +rather than writing something new + +0:13:20.000,0:13:22.560 +entirely + +0:13:32.399,0:13:36.639 +are there any language major modes that + +0:13:34.800,0:13:40.079 +have integrated already + +0:13:36.639,0:13:42.800 +uh not yet + +0:13:40.079,0:13:43.440 +so the there was a proposed web assembly + +0:13:42.800,0:13:46.839 +mode + +0:13:43.440,0:13:50.000 +but it's a new major mode in terms of + +0:13:46.839,0:13:52.880 +existing major mode there is the + +0:13:50.000,0:13:52.880 +typescript mode + +0:13:53.279,0:13:57.519 +but they're only discussing about + +0:13:55.600,0:14:02.079 +integration + +0:13:57.519,0:14:04.639 +they're not integrated yet + +0:14:02.079,0:14:05.360 +i think i can try writing the + +0:14:04.639,0:14:09.199 +integration + +0:14:05.360,0:14:11.839 +sometimes next month + +0:14:09.199,0:14:12.720 +uh basically what they want right now is + +0:14:11.839,0:14:16.160 +the + +0:14:12.720,0:14:19.199 +syntax highlighting and handling + +0:14:16.160,0:14:22.959 +synthetic highlighting and + +0:14:19.199,0:14:27.760 +code indentation for tsx + +0:14:22.959,0:14:31.839 +which is the embedded react + +0:14:27.760,0:14:31.839 +syntax inside typescript + +0:14:32.160,0:14:40.000 +so it turns out passing these tests + +0:14:36.399,0:14:40.000 +is very troublesome so + +0:14:40.639,0:14:47.040 +so trees that would be a crystal would + +0:14:43.920,0:14:47.040 +be a lot of help there + +0:14:49.920,0:14:59.839 +is there any link to the slides yes + +0:14:53.279,0:14:59.839 +i'll post it in irc later + +0:14:59.920,0:15:04.240 +regarding imax integration we will + +0:15:01.920,0:15:05.440 +always need to be a foreign library or + +0:15:04.240,0:15:09.920 +can it be included + +0:15:05.440,0:15:09.920 +linked directly in compilation + +0:15:10.839,0:15:17.600 +uh if if this is about the + +0:15:14.480,0:15:21.839 +core library itself + +0:15:17.600,0:15:23.440 +then i think it's uh answered it in the + +0:15:21.839,0:15:27.440 +first question + +0:15:23.440,0:15:29.920 +right now is a right now it's a + +0:15:27.440,0:15:30.959 +dynamic model but in the long run it + +0:15:29.920,0:15:34.000 +will better if + +0:15:30.959,0:15:39.839 +it's included in core emacs + +0:15:34.000,0:15:41.360 +for the language definitions themselves + +0:15:39.839,0:15:43.279 +it should be better if they are + +0:15:41.360,0:15:46.639 +distributed uh + +0:15:43.279,0:15:49.199 +separately like that right now so each + +0:15:46.639,0:15:49.680 +uh for each language there will be a + +0:15:49.199,0:15:52.639 +shared + +0:15:49.680,0:15:55.839 +library that will be loaded by the core + +0:15:52.639,0:15:55.839 +library at runtime + +0:16:00.480,0:16:04.240 +so the last question is the python mode + +0:16:02.480,0:16:06.160 +example is pretty good + +0:16:04.240,0:16:07.600 +is that something that one can use + +0:16:06.160,0:16:11.759 +already + +0:16:07.600,0:16:11.759 +yes i'm using it at work right now + +0:16:12.320,0:16:17.360 +i think that's all for that's all the + +0:16:14.639,0:16:17.360 +questions right + +0:16:19.199,0:16:27.839 +you are now unmuted yeah i think that's + +0:16:23.440,0:16:30.399 +all the questions on the pads so far um + +0:16:27.839,0:16:32.399 +so thank you but um there may be more + +0:16:30.399,0:16:36.639 +questions coming on irc + +0:16:32.399,0:16:39.680 +um i'll try to have a look + +0:16:36.639,0:16:40.560 +and we still have about 10 or 15 more + +0:16:39.680,0:16:43.600 +minutes so + +0:16:40.560,0:16:46.880 +um there's no rush to wrap up in case um + +0:16:43.600,0:16:46.880 +anyone has any more questions + +0:16:48.160,0:16:51.360 +uh yeah i just realized that uh i mixed + +0:16:50.880,0:16:54.959 +up the + +0:16:51.360,0:16:56.000 +video editing and i uh lost an entire + +0:16:54.959,0:17:00.880 +session on the + +0:16:56.000,0:17:00.880 +introduction to treesita oh + +0:17:01.120,0:17:05.839 +no worries + +0:17:06.640,0:17:20.079 +you are now muted + +0:17:18.079,0:17:21.679 +sounds like a perfect opportunity for + +0:17:20.079,0:17:24.000 +you to redo the introduction if you'd + +0:17:21.679,0:17:24.000 +like to + +0:17:24.640,0:17:30.000 +uh actually uh forgot a lot of that + +0:17:30.799,0:17:35.760 +and i'm with uh tired now so no i don't + +0:17:33.760,0:17:39.200 +think i can do it + +0:17:35.760,0:17:43.520 +it's uh 30 minutes until my bedtime + +0:17:39.200,0:17:46.640 +oh yeah yeah okay you are now unmuted + +0:17:43.520,0:17:50.480
