+
+00:00:00.080 --> 00:00:03.040
+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
