+hello EmacsConf this is john wigley I'm + +00:00:03.040 --> 00:00:04.960 +one of the co-maintainers of Emacs along + +00:00:04.960 --> 00:00:06.319 +with ellie zoretsky + +00:00:06.319 --> 00:00:09.280 +and lars ingebrigston and I wanted to + +00:00:09.280 --> 00:00:09.840 +give you + +00:00:09.840 --> 00:00:12.639 +a technical update on what has been + +00:00:12.639 --> 00:00:14.960 +happening + +00:00:14.960 --> 00:00:18.400 +with the Emacs in the last year so + +00:00:18.400 --> 00:00:20.640 +specifically uh we have a few notes that + +00:00:20.640 --> 00:00:21.600 +I've gotten from + +00:00:21.600 --> 00:00:24.480 +a call with ellie he's been in charge of + +00:00:24.480 --> 00:00:25.840 +directing most of the + +00:00:25.840 --> 00:00:28.000 +technical contributions on the mailing + +00:00:28.000 --> 00:00:30.160 +list and monitoring all the patches + +00:00:30.160 --> 00:00:33.200 +so I'm more here just as a messenger + +00:00:33.200 --> 00:00:35.840 +he says that we have good progress and + +00:00:35.840 --> 00:00:37.120 +support for cairo + +00:00:37.120 --> 00:00:39.040 +this is going to be enabled by default + +00:00:39.040 --> 00:00:40.320 +and emax 28 + +00:00:40.320 --> 00:00:42.480 +and cairo plus half buzz is going to be + +00:00:42.480 --> 00:00:44.800 +the preferred rendering combination + +00:00:44.800 --> 00:00:46.879 +so cairo support is not new but in the + +00:00:46.879 --> 00:00:48.719 +past there were a lot of bugs in the + +00:00:48.719 --> 00:00:51.440 +code and so it was made experimental + +00:00:51.440 --> 00:00:52.960 +so most of those bugs have been fixed + +00:00:52.960 --> 00:00:54.960 +recently and now it becomes the default + +00:00:54.960 --> 00:00:56.320 +and the next major version + +00:00:56.320 --> 00:00:58.320 +which will enable several good features + +00:00:58.320 --> 00:01:00.320 +such as color emojis if you're looking + +00:01:00.320 --> 00:01:01.680 +forward to those + +00:01:01.680 --> 00:01:04.720 +xft as a result is deprecated there are + +00:01:04.720 --> 00:01:06.560 +bugs not getting fixed in that code it + +00:01:06.560 --> 00:01:07.760 +doesn't appear to be very well + +00:01:07.760 --> 00:01:08.720 +maintained + +00:01:08.720 --> 00:01:10.960 +it was the most advanced font mac end + +00:01:10.960 --> 00:01:13.760 +and emax before cairo became dependable + +00:01:13.760 --> 00:01:15.920 +so now that we have a more a better + +00:01:15.920 --> 00:01:17.840 +maintained and available solution in + +00:01:17.840 --> 00:01:19.360 +cairo we're going to go from that + +00:01:19.360 --> 00:01:23.200 +go from xft to that native compilation + +00:01:23.200 --> 00:01:23.840 +in lisp + +00:01:23.840 --> 00:01:26.400 +will also be landing soon it's currently + +00:01:26.400 --> 00:01:28.080 +on a branch but there are several people + +00:01:28.080 --> 00:01:28.799 +using it + +00:01:28.799 --> 00:01:31.040 +they say they're very impressed it does + +00:01:31.040 --> 00:01:32.479 +require live gcc + +00:01:32.479 --> 00:01:35.600 +jit to be installed for it to work and + +00:01:35.600 --> 00:01:37.439 +this means you have to have gcc 10 + +00:01:37.439 --> 00:01:38.960 +installed + +00:01:38.960 --> 00:01:41.040 +execution of Emacs lisp with native + +00:01:41.040 --> 00:01:42.240 +compilation on + +00:01:42.240 --> 00:01:45.280 +is about 2.5 times faster than the + +00:01:45.280 --> 00:01:46.159 +bytecode + +00:01:46.159 --> 00:01:48.399 +interpreter we don't yet have any + +00:01:48.399 --> 00:01:49.439 +measurements on + +00:01:49.439 --> 00:01:51.600 +memory or how it affects resources + +00:01:51.600 --> 00:01:52.960 +besides cpu so + +00:01:52.960 --> 00:01:54.720 +we do look forward to having more + +00:01:54.720 --> 00:01:56.399 +numbers and analysis to see what the + +00:01:56.399 --> 00:01:58.320 +real impact of that is going to be + +00:01:58.320 --> 00:02:01.360 +also it may vary in compute advantage + +00:02:01.360 --> 00:02:02.799 +based on the type of workload that + +00:02:02.799 --> 00:02:04.320 +you're performing + +00:02:04.320 --> 00:02:06.240 +a downside to the native compilation at + +00:02:06.240 --> 00:02:08.080 +the moment is that it takes a long + +00:02:08.080 --> 00:02:10.720 +time to compile even when you're doing a + +00:02:10.720 --> 00:02:12.720 +16 core build of Emacs + +00:02:12.720 --> 00:02:14.959 +it can still take 15 minutes to compile + +00:02:14.959 --> 00:02:15.760 +Emacs + +00:02:15.760 --> 00:02:17.840 +and all of its in all of its lisp code + +00:02:17.840 --> 00:02:19.520 +with this enabled + +00:02:19.520 --> 00:02:21.840 +also this is going to have to happen on + +00:02:21.840 --> 00:02:23.120 +every user's machine + +00:02:23.120 --> 00:02:25.360 +because we cannot distribute the native + +00:02:25.360 --> 00:02:27.520 +compilation products they are specific + +00:02:27.520 --> 00:02:28.319 +to the compo + +00:02:28.319 --> 00:02:29.760 +to the processor that you might be + +00:02:29.760 --> 00:02:31.440 +running on so + +00:02:31.440 --> 00:02:33.920 +the emax distribution will remain much + +00:02:33.920 --> 00:02:35.680 +as it is now but if you want to have the + +00:02:35.680 --> 00:02:37.760 +benefits of natively compiled + +00:02:37.760 --> 00:02:39.599 +core lisp files you're going to have to + +00:02:39.599 --> 00:02:41.519 +spend that time and have gcc 10 + +00:02:41.519 --> 00:02:42.400 +available + +00:02:42.400 --> 00:02:45.840 +to get that compilation support um + +00:02:45.840 --> 00:02:48.959 +the gtk only build is being prepared + +00:02:48.959 --> 00:02:52.160 +for merging so what this does is it + +00:02:52.160 --> 00:02:52.959 +throws away + +00:02:52.959 --> 00:02:55.120 +most of the other tool kits that Emacs + +00:02:55.120 --> 00:02:56.000 +was using + +00:02:56.000 --> 00:02:59.280 +and relies only on gtk making Emacs + +00:02:59.280 --> 00:03:01.760 +much more of a gtk application than it + +00:03:01.760 --> 00:03:03.920 +has been + +00:03:03.920 --> 00:03:06.480 +the main issue here is that we were + +00:03:06.480 --> 00:03:08.480 +abusing gtk in some ways that weren't + +00:03:08.480 --> 00:03:09.360 +really meant + +00:03:09.360 --> 00:03:10.879 +and now we're going to be more of a + +00:03:10.879 --> 00:03:12.879 +first club gtk will be more of a first + +00:03:12.879 --> 00:03:14.080 +class citizen in the + +00:03:14.080 --> 00:03:17.040 +approach and the ways that we use it and + +00:03:17.040 --> 00:03:17.440 +and + +00:03:17.440 --> 00:03:19.280 +be using it in the ways that the gtk + +00:03:19.280 --> 00:03:21.200 +developers intended + +00:03:21.200 --> 00:03:23.360 +there is going to be much more support + +00:03:23.360 --> 00:03:24.640 +for xt mouse + +00:03:24.640 --> 00:03:27.280 +so xt mouse allows you to use your mouse + +00:03:27.280 --> 00:03:29.120 +inside of a terminal window + +00:03:29.120 --> 00:03:30.799 +which you could do before but there were + +00:03:30.799 --> 00:03:33.120 +certain aspects such as menus + +00:03:33.120 --> 00:03:36.159 +that weren't supported so instead of + +00:03:36.159 --> 00:03:38.239 +having kind of partial support for mouse + +00:03:38.239 --> 00:03:39.840 +inside of an x term with xt + +00:03:39.840 --> 00:03:42.879 +mouse you get full support this is going + +00:03:42.879 --> 00:03:44.959 +to allow + +00:03:44.959 --> 00:03:46.720 +changes in the way that things can be + +00:03:46.720 --> 00:03:48.159 +bound the ways that + +00:03:48.159 --> 00:03:51.200 +uh key bindings can the mouse events can + +00:03:51.200 --> 00:03:53.200 +be mapped to key bindings while in + +00:03:53.200 --> 00:03:56.879 +x terms and um yeah little by little + +00:03:56.879 --> 00:03:58.480 +this support is being extended even + +00:03:58.480 --> 00:03:59.040 +further + +00:03:59.040 --> 00:04:01.599 +so we look forward to seeing that + +00:04:01.599 --> 00:04:04.080 +develop in the near term + +00:04:04.080 --> 00:04:06.239 +once this is merged by the way also then + +00:04:06.239 --> 00:04:08.080 +Emacs will have mouse support in every + +00:04:08.080 --> 00:04:09.840 +one of its available configurations + +00:04:09.840 --> 00:04:12.720 +which has not been true until now Emacs + +00:04:12.720 --> 00:04:14.680 +27 will be soon releasing + +00:04:14.680 --> 00:04:17.519 +27.2 and the pretest for that should + +00:04:17.519 --> 00:04:19.919 +begin sometime soon after Emacs comp is + +00:04:19.919 --> 00:04:20.880 +done + +00:04:20.880 --> 00:04:23.360 +and finally Emacs 28 is going to get + +00:04:23.360 --> 00:04:24.800 +better emoji support + +00:04:24.800 --> 00:04:26.479 +right now emojis are registered + +00:04:26.479 --> 00:04:29.120 +internally within Emacs as symbols + +00:04:29.120 --> 00:04:31.759 +which works in some ways but does not + +00:04:31.759 --> 00:04:33.759 +support some of the special features + +00:04:33.759 --> 00:04:37.360 +of of emojis such as different + +00:04:37.360 --> 00:04:40.000 +skin tones for the hand emoji or face + +00:04:40.000 --> 00:04:41.120 +emojis + +00:04:41.120 --> 00:04:43.280 +in Emacs 28 emojis are going to have + +00:04:43.280 --> 00:04:45.199 +their own support within the sequel + +00:04:45.199 --> 00:04:47.199 +c code and then this is going to allow + +00:04:47.199 --> 00:04:49.360 +those types of variations and other + +00:04:49.360 --> 00:04:52.720 +emoji specific font setups so that is + +00:04:52.720 --> 00:04:54.639 +everything for Emacs + +00:04:54.639 --> 00:04:56.720 +in the future I don't have a timeline + +00:04:56.720 --> 00:04:59.120 +for you on when 28 will be available + +00:04:59.120 --> 00:05:01.520 +but 27 is going to keep improving until + +00:05:01.520 --> 00:05:02.720 +we're ready to get there + +00:05:02.720 --> 00:05:04.479 +so have fun with the rest of you max + +00:05:04.479 --> 00:05:06.479 +conf and I hope to see you there + +00:05:06.479 --> 00:05:09.199 +bye |
