+00:00.000 --> 00:06.066 +Hello, and welcome to Emacs 30 Highlights at EmacsConf 2024. + +00:06.100 --> 00:08.833 +Before I begin, I'd like to thank the organizers + +00:08.866 --> 00:11.800 +and everyone involved for putting this all together. + +00:11.800 --> 00:13.733 +While this talk is being pre-recorded, + +00:13.766 --> 00:15.233 +my experience from the last few years + +00:15.266 --> 00:19.100 +assures me that it will be a great experience for everyone. + +00:19.133 --> 00:21.300 +My name is Philip Kaludercic. + +00:21.333 --> 00:24.466 +I am a core contributor and ELPA co-maintainer. + +00:24.500 --> 00:26.066 +I was honored when Sacha asked me + +00:26.100 --> 00:28.333 +to take over the slot for this year. + +00:28.366 --> 00:29.866 +In the past few iterations, + +00:29.900 --> 00:32.133 +John Wiegley has filled a similar presentation + +00:32.166 --> 00:35.666 +focusing on more general Emacs development updates. + +00:35.700 --> 00:00:38.501 +This year, I will specifically focus on + +00:00:38.502 --> 00:00:41.900 +highlight features from the upcoming Emacs 30 release, + +00:41.933 --> 00:44.200 +which might or might not have been released + +00:44.200 --> 00:00:48.059 +by the time you are seeing this. + +00:00:48.060 --> 00:51.266 +As you can imagine, everything new about Emacs + +00:51.300 --> 00:55.133 +can always be found in the Emacs NEWS file. + +00:55.166 --> 00:57.100 +Or, alternatively, + +00:57.133 --> 01:01.800 +if one doesn't want to read through the 3,000 lines here, + +01:01.800 --> 01:05.233 +one can also take a look at the Emacs FAQ + +01:05.266 --> 01:08.000 +and then go to the what's new about + +01:08.000 --> 01:12.300 +or what's different about Emacs 30 node. + +01:12.333 --> 01:14.700 +Next to these two official options, + +01:14.733 --> 01:18.200 +I also have a page on Emacs Wiki + +01:18.200 --> 01:21.300 +called EmacsThirtyHighlights, + +01:21.333 --> 01:24.266 +highlighting some of the interesting features + +01:24.300 --> 01:28.433 +with some context and suggestions on how to try them out. + +01:28.466 --> 01:30.033 +This is more of a collaborative effort. + +01:30.066 --> 01:32.733 +So if you see this and think something is missing, + +01:32.766 --> 01:34.500 +feel free to add it. + +01:34.533 --> 01:36.833 +So without further ado, + +01:36.866 --> 01:41.800 +let's begin taking a look at new features in Emacs 30. + +NOTE Android + +01:41.800 --> 01:44.700 +The biggest one, and the one I want to mention first, + +01:44.733 --> 01:49.033 +is Android support, native Android support. + +01:49.066 --> 01:51.833 +As you can see here, Emacs has been ported + +01:51.866 --> 01:53.666 +to the Android operating system. + +01:53.700 --> 01:56.500 +What this means is that from Emacs 30 onwards, + +01:56.533 --> 02:01.066 +you can build Android to target Android devices natively + +02:01.100 --> 02:06.733 +and using a graphical interface. + +02:06.766 --> 02:08.433 +While it has been possible to run Emacs + +02:08.466 --> 02:11.133 +inside of terminal emulators on Android for a while, + +02:11.166 --> 02:13.900 +this actually means that you can use Emacs + +02:13.933 --> 02:17.533 +on an Android device, a phone or a tablet, + +02:17.566 --> 02:20.933 +and have all the usual advantages from GUI Emacs, + +02:20.966 --> 02:23.466 +such as the ability to bind all commands + +02:23.500 --> 02:25.466 +without having to worry about-- + +02:25.500 --> 02:27.266 +all keys without having to worry + +02:27.300 --> 02:29.033 +about terminal compatibility issues, + +02:29.066 --> 02:32.733 +displaying images and multiple fonts + +02:32.766 --> 02:35.333 +on the same display of different sizes. + +02:35.366 --> 02:37.300 +I should have a recording + +02:37.333 --> 02:42.200 +of that somewhere here--here we are-- + +02:42.200 --> 02:44.100 +which I made earlier on my phone, + +02:44.133 --> 02:47.266 +because I'm recording this on a laptop-- + +02:47.300 --> 02:50.466 +where we can see how touch interaction works + +02:50.500 --> 02:53.333 +on an Android phone. I can switch between buffers. + +02:53.366 --> 02:56.100 +Here I've connected an external keyboard, + +02:56.133 --> 02:57.800 +opening the Emacs website. + +02:57.800 --> 00:03:02.559 +We have images that we can interact with. + +00:03:02.560 --> 00:03:04.319 +We could resize them if we wanted to + +00:03:04.320 --> 03:07.400 +with the image resizing commands. + +03:07.400 --> 03:10.300 +Pinch-to-zoom works, so it + +03:10.333 --> 03:12.733 +does realize what touchscreen interactions are. + +03:12.766 --> 03:15.233 +With an external mouse, and for example, + +03:15.266 --> 03:17.800 +enabling context menu mode, + +03:17.800 --> 03:23.066 +I can even pop up little interaction windows, + +03:23.100 --> 00:03:28.139 +which one you would usually also know from GUI Emacs. + +00:03:28.140 --> 03:33.200 +TUI Emacs actually also supports them since a while now. + +03:33.200 --> 03:34.600 +And in this case, I'm demonstrating + +03:34.600 --> 03:36.000 +how even the touchscreen events + +03:36.000 --> 03:39.133 +can be inspected using the usual help system, + +03:39.166 --> 03:43.333 +and how context-mode notices + +03:43.366 --> 03:45.200 +where we are and allows me to, for example, + +03:45.200 --> 03:47.800 +evaluate this specific region, + +03:47.800 --> 03:49.300 +which I've highlighted down there, + +03:49.333 --> 03:58.300 +binding a command to touch-screen-scroll. Yeah. + +03:58.333 --> 04:00.533 +One should note that these additions, + +04:00.566 --> 04:02.400 +for example touchscreen interaction, + +04:02.400 --> 04:03.833 +are not specific to Android, + +04:03.866 --> 04:07.066 +but they also are supported in other operating systems, + +04:07.100 --> 04:12.200 +such as Wayland and Xorg, which are not operating systems, + +04:12.200 --> 04:15.300 +and Windows, insofar as they have touchscreen, + +04:15.333 --> 00:04:18.419 +and devices have touchscreen support. + +00:04:18.420 --> 04:21.300 +One should mention, or I want to mention, + +04:21.333 --> 04:24.666 +that the main developer behind this feature, Po Lu, + +04:24.700 --> 04:27.500 +should be complimented for the additional effort he put + +04:27.533 --> 00:04:31.019 +into making sure that Emacs for Android + +00:04:31.020 --> 04:34.133 +can be built using only a free software toolchain, + +04:34.166 --> 00:04:36.359 +which is certainly not something one has come to expect + +00:04:36.360 --> 04:40.700 +from working on Android applications, + +04:40.733 --> 04:43.833 +as usually you have to agree to some terms and conditions + +04:43.866 --> 00:04:46.519 +for Google-specific software. + +00:04:46.520 --> 04:49.633 +Final note is that if you try and look for this online, + +04:49.666 --> 04:52.133 +there are APKs you can find, + +04:52.166 --> 04:54.666 +but some of them might be outdated. + +04:54.700 --> 04:59.333 +To the best of my knowledge, Po Lu has... + +04:59.366 --> 05:03.400 +Emacs 30 Android Sourceforge... + +05:03.400 --> 05:06.500 +He has set up some system where here in Sourceforge, + +05:06.533 --> 05:12.433 +there are regular and updated + +05:12.466 --> 05:14.500 +APK files which you can download + +05:14.533 --> 05:16.933 +to avoid having to build it yourself, + +05:16.966 --> 05:18.866 +testing out the newest version + +05:18.900 --> 05:24.133 +in case there are some bugs which you'd like to report. + +05:24.166 --> 05:33.100 +Which-key is a package which has now been moved + +05:33.133 --> 05:35.266 +from ELPA to the core. + +05:35.300 --> 00:05:39.179 +If you haven't heard of which-key before, the idea is, + +00:05:39.180 --> 05:41.633 +or the general pitch is that which-key + +05:41.666 --> 05:45.233 +is a additional documentation interface for Emacs + +05:45.266 --> 05:49.700 +for displaying various keys which you could input, + +05:49.733 --> 00:05:53.439 +or various keys and key maps + +00:05:53.440 --> 05:54.833 +that have been partially inputted. + +05:54.866 --> 05:57.633 +A better way to demonstrate this + +05:57.666 --> 05:59.300 +or to explain this is just to show it. + +05:59.333 --> 06:03.466 +If we enable the which-key mode--it's a global minor mode-- + +06:03.500 --> 06:06.333 +then I can press, for example, C-x, + +06:06.366 --> 06:08.700 +which is a prefix for the C-x keymap. + +06:08.733 --> 06:12.433 +Then down here in the buffer, in this window down here, + +06:12.466 --> 06:15.333 +we see various commands which we could invoke + +06:15.366 --> 06:17.900 +and the keys to invoke them with. + +06:17.933 --> 06:23.000 +For example, if I wanted to say C-x i for insert-file, + +06:23.000 --> 06:27.233 +then I just have to press i to highlight it once again. + +06:27.266 --> 06:32.600 +It should be down here. Pressing i without having to repeat + +06:32.600 --> 06:34.733 +the entire key code again, + +06:34.766 --> 06:37.200 +the partial key code again, just works. + +06:37.200 --> 06:41.533 +This is different from the feature which Emacs has already, + +06:41.566 --> 06:45.400 +which is if you have input the partial keychord, + +06:45.400 --> 06:47.033 +you can press C-h + +06:47.066 --> 06:51.000 +and then a help buffer pops up with a listing + +06:51.000 --> 06:54.066 +of all keybindings that start with C-x. + +06:54.100 --> 06:56.633 +The information is the same, the presentation is different, + +06:56.666 --> 06:59.066 +because now if I wanted to do C-x i, + +06:59.100 --> 00:07:03.339 +I have to repeat the entire keychord again. + +00:07:03.340 --> 07:09.466 +So it's a matter of personal preference, which you prefer. + +07:09.500 --> 00:07:10.959 +This is more of a traditional static approach + +00:07:10.960 --> 07:19.633 +because I get a help buffer which I can search + +07:19.666 --> 07:20.900 +using usual key commands, + +07:20.933 --> 07:28.133 +while which-key is more of a transient and modern. + +07:28.166 --> 07:31.400 +Some might prefer that approach + +07:31.400 --> 00:07:35.719 +to solving the same problem. + +00:07:35.720 --> 07:39.100 +Also, don't forget to check out the customization group + +07:39.133 --> 07:41.933 +for which-key which has a number of options + +07:41.966 --> 00:07:45.719 +which you might or might not be interested in. + +NOTE EditorConfig + +00:07:45.720 --> 07:50.866 +Next up, Emacs 30 has built-in EditorConfig support. + +07:50.900 --> 07:53.633 +If you have not heard of EditorConfig before, + +07:53.666 --> 00:07:56.639 +I believe I've linked to it down here somewhere. + +00:07:56.640 --> 00:08:00.119 +Ah, there it is, EditorConfig. + +00:08:00.120 --> 00:08:09.419 +This is a file format used to specify + +00:08:09.420 --> 08:12.133 +common formatting rules in an editor-agnostic way. + +08:12.166 --> 08:16.266 +You might compare it to .dir-locals.el files, + +08:16.300 --> 08:19.333 +which is a sort of an s-expression + +08:19.366 --> 08:22.233 +for setting file-local variables in Emacs. + +08:22.266 --> 08:27.266 +Of course, this is restricted to the common subset + +08:27.300 --> 08:29.400 +of what all editors should understand. + +08:29.400 --> 08:31.833 +For example, indentation styles, + +08:31.866 --> 00:08:35.119 +whether you prefer tabs or spaces, + +00:08:35.120 --> 08:38.733 +tab width, file encoding, and so on. + +08:38.766 --> 00:08:43.919 +So it's nothing too advanced, but it's something... + +00:08:43.920 --> 08:48.500 +It is a file format which one sees popping up more + +08:48.533 --> 08:50.433 +and more often in lots of projects + +08:50.466 --> 08:53.600 +which want to enforce a consistent indentation style + +08:53.600 --> 08:56.633 +or formatting rules for all editors in a project. + +08:56.666 --> 09:00.200 +Having this built in is certainly useful in Emacs. + +09:00.200 --> 09:03.466 +Though one should note that it's not enabled by default. + +09:03.500 --> 00:09:10.939 +You still have to enable the global minor mode, + +00:09:10.940 --> 09:14.200 +which is simply turning on this one option. + +09:14.200 --> 09:15.500 +Shouldn't be more than that, + +09:15.533 --> 09:18.633 +and then Emacs will respect the rules. + +09:18.666 --> 00:09:23.640 +If it finds a .editorconfig file in the project directory, + +00:09:23.641 --> 00:09:25.320 +then it will respect those rules + +00:09:25.321 --> 00:09:27.320 +without having to do anything else. + +NOTE use-package integration with package-vc + +00:09:27.310 --> 00:09:33.567 +Next up, use-package integration with package-vc. + +00:09:33.568 --> 00:09:36.533 +For those not familiar with either of the two, + +00:09:36.534 --> 00:09:37.533 +or at least one of the two, + +00:09:37.534 --> 00:09:40.699 +use-package is a popular configuration macro. + +00:09:40.700 --> 00:09:42.833 +What it does is it allows + +00:09:42.866 --> 00:09:46.233 +users to declaratively specify packages + +00:09:46.266 --> 00:09:48.900 +they would like to have installed and configured + +00:09:48.900 --> 00:09:51.659 +in their configuration file, + +00:09:51.660 --> 00:09:54.400 +so that, for example, if you copy your init.el + +00:09:54.433 --> 00:09:55.900 +from one system to another, + +00:09:55.900 --> 00:09:58.500 +it could bootstrap the entire configuration, + +00:09:58.500 --> 00:10:00.733 +downloading all the packages you want + +00:10:00.766 --> 00:10:02.366 +without having to manually do this + +00:10:02.400 --> 00:10:05.139 +on every system you'd like to use. + +00:10:05.140 --> 00:10:07.600 +This allows configurations + +00:10:07.633 --> 00:10:10.859 +to be self-encapsulated and portable. + +00:10:10.860 --> 00:10:15.059 +package-vc is an extension of package.el, + +00:10:15.060 --> 00:10:19.400 +which allows installing packages from an alternative. + +00:10:19.433 --> 00:10:22.366 +Instead of using the standard way to install packages, + +00:10:22.400 --> 00:10:26.499 +which is just download tarball and unpack it, + +00:10:26.500 --> 00:10:27.933 +byte compile, and so on, + +00:10:27.966 --> 00:10:32.399 +it will fetch the files for a package + +00:10:32.400 --> 00:10:34.966 +directly from the source code repository + +00:10:35.000 --> 00:10:37.233 +and initialize it in such a way + +00:10:37.266 --> 00:10:38.800 +that package.el can work with it. + +00:10:38.833 --> 00:10:44.239 +So it's just a front-end for installing packages. + +00:10:44.240 --> 00:10:46.500 +Even though these two were added to Emacs 29, + +00:10:46.500 --> 00:10:48.366 +we didn't have the time to work on the + +00:10:48.400 --> 00:10:52.500 +use-package integration of package-vc into use-package, + +00:10:52.500 --> 00:10:54.600 +which has been changed now. + +00:10:54.633 --> 00:11:00.139 +What we have with Emacs 30 is that + +00:11:00.140 --> 00:11:02.833 +there is a :vc keyword for use-package + +00:11:02.866 --> 00:11:05.200 +with which we can instruct use-package + +00:11:05.233 --> 00:11:10.239 +to not download a package using tarball, + +00:11:10.240 --> 00:11:12.433 +but instead to fetch the source code + +00:11:12.466 --> 00:11:13.766 +from a source code repository. + +00:11:13.800 --> 00:11:15.566 +This is useful if you, for example, + +00:11:15.600 --> 00:11:18.200 +have packages which you yourself work on + +00:11:18.233 --> 00:11:19.933 +and know that you always want to have + +00:11:19.966 --> 00:11:21.900 +the development version of the package + +00:11:21.900 --> 00:11:26.819 +where you can directly commit changes you've made + +00:11:26.820 --> 00:11:29.733 +to the repository and push them upstream. + +00:11:29.766 --> 00:11:32.100 +Or, if you know that you want to contribute to a package, + +00:11:32.100 --> 00:11:34.966 +you can use package-vc to download the source code, + +00:11:35.000 --> 00:11:37.366 +have all the version control information, + +00:11:37.400 --> 00:11:41.739 +prepare a patch and send it upstream. + +00:11:41.740 --> 00:11:43.800 +In these examples here, + +00:11:43.833 --> 00:11:49.166 +the first example Lisp instructs package-vc + +00:11:49.200 --> 00:11:52.366 +to download the source code from a URL. + +00:11:52.400 --> 00:11:55.400 +So this is a git URL where it will download + +00:11:55.433 --> 00:11:57.400 +the source code from, and in this case, + +00:11:57.433 --> 00:12:00.000 +choose the newest checkout of the source code, + +00:12:00.033 --> 00:12:04.939 +not the latest release. Down here, we have another example. + +00:12:04.940 --> 00:12:08.766 +I prefer to consider the following example here. + +00:12:08.800 --> 00:12:10.733 +If we just had written this, + +00:12:10.766 --> 00:12:13.200 +then package-vc would use the metadata + +00:12:13.233 --> 00:12:15.000 +which an ELPA server provides + +00:12:15.033 --> 00:12:20.166 +to fetch the URL from the official repository of, + +00:12:20.200 --> 00:12:22.833 +in this case, BBDB, without having to... + +00:12:22.866 --> 00:12:27.733 +It would be more or less the same like this up here, + +00:12:27.766 --> 00:12:32.700 +with the simple difference that package-vc integration + +00:12:32.700 --> 00:12:36.300 +into use-package doesn't check out the latest commit, + +00:12:36.300 --> 00:12:37.766 +but the latest release, + +00:12:37.800 --> 00:12:44.979 +just to keep configurations more deterministic by default. + +00:12:44.980 --> 00:12:47.566 +Of course, if you prefer to use latest commit, + +00:12:47.600 --> 00:12:52.179 +you can use a package-vc install command + +00:12:52.180 --> 00:12:54.933 +or just update the package manually yourself, + +00:12:54.966 --> 00:13:01.779 +which you can use using package-vc-upgrade. + +00:13:01.780 --> 00:13:04.366 +Next, I'd like to focus on a few features + +00:13:04.400 --> 00:13:07.000 +which one might not necessarily realize directly, + +00:13:07.033 --> 00:13:11.559 +but will hopefully improve your experience with Emacs. + +NOTE JSON + +00:13:11.560 --> 00:13:15.133 +First up in this list is a new JSON parser. + +00:13:15.166 --> 00:13:21.959 +Let's maybe show the source code for that one: + +00:13:21.960 --> 00:13:39.533 +not json.el, json.c. The history of JSON parsing in Emacs + +00:13:39.566 --> 00:13:43.366 +started with Emacs 23 with the addition of json.el. + +00:13:43.400 --> 00:13:46.766 +This was the file which we had just opened a moment ago. + +00:13:46.800 --> 00:13:50.366 +This is a JSON parser in Emacs Lisp. + +00:13:50.400 --> 00:13:53.233 +It's fine, it does the job, but it can get slow + +00:13:53.266 --> 00:13:55.000 +if we have a situation like where + +00:13:55.033 --> 00:14:00.319 +Eglot uses a LSP server to communicate with + +00:14:00.320 --> 00:14:02.999 +and the LSP server can get a bit chatty, + +00:14:03.000 --> 00:14:05.133 +sending a lot of JSON data, + +00:14:05.166 --> 00:14:07.966 +which all has to be parsed and garbage collected, + +00:14:08.000 --> 00:14:09.933 +which can slow down Emacs a bit. + +00:14:09.966 --> 00:14:13.733 +The situation was improved upon in Emacs 29 + +00:14:13.766 --> 00:14:18.000 +when JSON parsing was added to the core. + +00:14:18.033 --> 00:14:21.000 +This was the json.c file, which we see on this side, + +00:14:21.033 --> 00:14:22.733 +the old version of the json.c file, + +00:14:22.766 --> 00:14:26.700 +which employed the Jansson library (it's the C library) + +00:14:26.700 --> 00:14:31.899 +for parsing and accelerating JSON parsing in Emacs. + +00:14:31.900 --> 00:14:33.966 +This was good enough, + +00:14:34.000 --> 00:14:36.200 +or it certainly improved the situation + +00:14:36.233 --> 00:14:38.300 +for a lot of LSP clients. + +00:14:38.300 --> 00:14:44.766 +But in Emacs 30, the situation has been improved once more + +00:14:44.800 --> 00:14:49.800 +with the addition of a JSON parser directly in Emacs. + +00:14:49.833 --> 00:14:53.566 +So instead of using an external library, + +00:14:53.600 --> 00:14:57.400 +there's a custom JSON parser written in C in the Emacs core, + +00:14:57.433 --> 00:15:01.539 +which directly generates Elisp objects. + +00:15:01.540 --> 00:15:05.033 +The advantage to this approach + +00:15:05.066 --> 00:15:06.433 +compared to the Jansson approach + +00:15:06.466 --> 00:15:07.933 +is that there's no intermediate format + +00:15:07.966 --> 00:15:09.200 +which has to be allocated + +00:15:09.233 --> 00:15:11.500 +and memory managed and freed again, + +00:15:11.500 --> 00:15:19.539 +which of course incurs an additional performance overhead. + +00:15:19.540 --> 00:15:22.433 +Next to this, there's also a custom serializer + +00:15:22.466 --> 00:15:29.239 +for JSON contents translating a JSON object into a string. + +00:15:29.240 --> 00:15:30.640 +... The consequence of this is that + +00:15:30.641 --> 00:15:35.519 +there is absolutely no dependency on Jansson anymore. + +00:15:35.520 --> 00:15:38.533 +This in turn means that now all Emacs users + +00:15:38.566 --> 00:15:39.800 +from Emacs 30 onwards + +00:15:39.833 --> 00:15:42.733 +can take advantage of this new JSON parser + +00:15:42.766 --> 00:15:44.933 +and don't have to worry about whether + +00:15:44.966 --> 00:15:47.633 +or not they have Jansson, this JSON parsing library, + +00:15:47.666 --> 00:15:50.433 +installed on their system or not when they want + +00:15:50.466 --> 00:15:56.679 +to take advantage of this accelerated JSON parsing. + +NOTE Native compilation + +00:15:56.680 --> 00:16:00.366 +Next up, another behind-the-scenes feature + +00:16:00.400 --> 00:16:06.406 +is that if you build Emacs on your own from source, + +00:16:06.407 --> 00:16:07.766 +you might know that if you wanted + +00:16:07.800 --> 00:16:09.533 +to use native compilation, + +00:16:09.566 --> 00:16:12.379 +so the translation of Elisp bytecodes + +00:16:12.380 --> 00:16:15.533 +to whatever the native assembly + +00:16:15.566 --> 00:16:19.133 +or native instruction set is on your system, + +00:16:19.166 --> 00:16:24.339 +you have to specify with native compilation. + +00:16:24.340 --> 00:16:25.933 +when invoking the configure script, + +00:16:25.966 --> 00:16:28.366 +otherwise it would not have been enabled at all. + +00:16:28.400 --> 00:16:32.479 +With Emacs 30, this step is not necessary anymore. + +00:16:32.480 --> 00:16:36.233 +The configure script will automatically check + +00:16:36.266 --> 00:16:41.700 +if you have the libgccjit library installed on your system, + +00:16:41.700 --> 00:16:42.766 +and if that is so, + +00:16:42.800 --> 00:16:45.566 +then native compilation will be enabled by default. + +00:16:45.600 --> 00:16:49.400 +In other words, if you have an issue with native compilation + +00:16:49.433 --> 00:16:52.500 +or prefer not to use it for whatever reason, + +00:16:52.500 --> 00:16:55.533 +you now have to type --without-native-compilation + +00:16:55.566 --> 00:16:58.433 +when compiling Emacs to prevent this from happening. + +00:16:58.466 --> 00:17:02.433 +But native compilation was added in Emacs 28 + +00:17:02.466 --> 00:17:04.333 +and has proven to be a very stable + +00:17:04.366 --> 00:17:06.233 +and useful feature for most people, + +00:17:06.266 --> 00:17:09.400 +so there's probably no reason to do this + +00:17:09.433 --> 00:17:11.133 +and you can just invoke the configure script + +00:17:11.166 --> 00:17:16.300 +with one argument less. Right, and I'd like to finish up + +00:17:16.300 --> 00:17:19.500 +with a few smaller features, a few smaller highlights. + +00:17:19.500 --> 00:17:29.639 +Maybe we can go back to the listing here. Here we have it. + +NOTE Tree-sitter + +00:17:29.640 --> 00:17:32.833 +There are a few new major modes + +00:17:32.866 --> 00:17:34.333 +based on the tree-sitter library. + +00:17:34.366 --> 00:17:37.939 +tree-sitter is this parser library + +00:17:37.940 --> 00:17:39.933 +which has been integrated into Emacs 29. + +00:17:39.966 --> 00:17:44.100 +It allows the integration + +00:17:44.100 --> 00:17:48.400 +of external, specialized, and quick parsers into Emacs, + +00:17:48.433 --> 00:17:52.133 +which improve stuff like syntax highlighting, indentation, + +00:17:52.166 --> 00:17:55.233 +structural navigation, imenu support, + +00:17:55.266 --> 00:18:01.033 +by simply having a better understanding of, for example, + +00:18:01.066 --> 00:18:03.900 +a HTML file, or a Lua file, a PHP file, + +00:18:03.900 --> 00:18:06.233 +than what people usually implement + +00:18:06.266 --> 00:18:10.366 +using regular expressions in traditional major modes. + +00:18:10.400 --> 00:18:16.779 +So, a few new major modes which you can try out here. + +NOTE Completion preview mode + +00:18:16.780 --> 00:18:20.033 +Another interesting feature is the completion-preview-mode. + +00:18:20.066 --> 00:18:22.966 +We can maybe try it out here in the scratch buffer. + +00:18:23.000 --> 00:18:28.300 +If I enable completion-preview-mode... + +00:18:28.300 --> 00:18:32.033 +This is a non-global minor mode, + +00:18:32.066 --> 00:18:38.600 +which will display completion options inline using overlays. + +00:18:38.633 --> 00:18:43.133 +For example, if I start typing a longer symbol like define, + +00:18:43.166 --> 00:18:48.200 +now we have a derived mode. It suggests me to... + +00:18:48.233 --> 00:18:51.133 +I can just press TAB and then it completes the option here, + +00:18:51.166 --> 00:18:51.933 +but it didn't actually... + +00:18:51.966 --> 00:18:55.333 +It's not actually modifying the buffer, it's not pressing, + +00:18:55.366 --> 00:18:57.100 +these are just overlays, + +00:18:57.100 --> 00:18:59.533 +so if I move around, it gets deleted. + +00:18:59.566 --> 00:19:02.619 +It wouldn't get saved if I were to save the buffer. + +00:19:02.620 --> 00:19:04.966 +The same also should work in a shell buffer. + +00:19:05.000 --> 00:19:08.366 +If I enable completion preview mode here and start... + +00:19:08.400 --> 00:19:12.800 +In this case, I'm using the bash completion package, + +00:19:12.833 --> 00:19:15.000 +which provides additional completion information. + +00:19:15.033 --> 00:19:17.933 +This is not only limited to programming systems, + +00:19:17.966 --> 00:19:22.900 +but anywhere where you have completion at point in Emacs. + +00:19:22.900 --> 00:19:26.159 +I can start typing here, ignore, and put ignore-backups, + +00:19:26.160 --> 00:19:30.000 +and it hints to the options which I have + +00:19:30.033 --> 00:19:34.200 +and allows me to complete them quickly. + +NOTE package-isolate + +00:19:34.233 --> 00:19:37.966 +Another small feature is the package-isolate command. + +00:19:38.000 --> 00:19:40.000 +What this does is it will start + +00:19:40.033 --> 00:19:42.800 +or it will prompt me for packages + +00:19:42.833 --> 00:19:44.333 +I have installed in my system + +00:19:44.366 --> 00:19:46.500 +and will start an isolated + +00:19:46.500 --> 00:19:51.133 +or like "emacs -Q"-ish instance of emacs + +00:19:51.166 --> 00:19:53.333 +with only these packages installed. + +00:19:53.366 --> 00:20:00.439 +So for example, if I said I want slime and I want diff-hl, + +00:20:00.440 --> 00:20:02.700 +then this is a new Emacs window. + +00:20:02.700 --> 00:20:04.533 +It's unrelated to the one around. + +00:20:04.566 --> 00:20:06.500 +It uses the same executable, of course, + +00:20:06.500 --> 00:20:09.939 +but will not load your configuration file + +00:20:09.940 --> 00:20:13.679 +or any other further customizations on your system. + +00:20:13.680 --> 00:20:15.533 +All it does, it will ensure + +00:20:15.566 --> 00:20:17.933 +that these packages, which are listed here, + +00:20:17.966 --> 00:20:24.599 +so in our case SLIME and dependencies of SLIME and diff-hl, + +00:20:24.600 --> 00:20:25.300 +in the system + +00:20:25.300 --> 00:20:29.100 +so that I could, for example, as you can see here, + +00:20:29.100 --> 00:20:32.139 +diff-hl-mode works. + +00:20:32.140 --> 00:20:34.766 +Okay, this is not a version-controlled file. + +00:20:34.800 --> 00:20:41.200 +Maybe if we take a look at, have I enabled diff-hl-mode? + +00:20:41.233 --> 00:20:44.600 +It's enabled in this case. What diff-hl-mode does + +00:20:44.633 --> 00:20:48.300 +is it displays these version control changes + +00:20:48.300 --> 00:20:49.566 +in the fringe of a buffer. + +00:20:49.600 --> 00:20:54.133 +And even though this is a uncustomized version of Emacs, + +00:20:54.166 --> 00:20:56.333 +or an uncustomized instance of Emacs, + +00:20:56.366 --> 00:20:59.000 +it was easy for me to load this one package, + +00:20:59.033 --> 00:21:02.033 +or these two packages and all the dependencies necessary. + +00:21:02.066 --> 00:21:05.300 +As you can imagine, the main purpose for this + +00:21:05.300 --> 00:21:07.733 +is to make debugging issues easier. + +00:21:07.766 --> 00:21:10.566 +If you want to report about an issue + +00:21:10.600 --> 00:21:14.900 +you have with a package. And if I close this, it's closed + +00:21:14.900 --> 00:21:16.919 +and everything's thrown away. + +NOTE Reindenting + +00:21:16.920 --> 00:21:19.000 +Last up, a nice feature I think + +00:21:19.033 --> 00:21:20.933 +a lot of people will appreciate is, + +00:21:20.966 --> 00:21:24.300 +if you are familiar with... Let's open a text buffer. + +00:21:24.300 --> 00:21:30.279 +The M-q key is traditionally bound to fill-paragraph. + +00:21:30.280 --> 00:21:32.200 +What this means is that... + +00:21:32.233 --> 00:21:35.000 +Let's, for example, copy this text from here + +00:21:35.033 --> 00:21:40.366 +and squash it all into one line. If I press M-q here, + +00:21:40.400 --> 00:21:42.719 +then the lines will be broken + +00:21:42.720 --> 00:21:49.879 +according to the fill column indicator up here. + +00:21:49.880 --> 00:21:52.600 +This is the traditional usage of M-q, + +00:21:52.633 --> 00:21:54.200 +and it still works in text-mode buffers, + +00:21:54.233 --> 00:21:55.859 +but in prog-mode buffers-- + +00:21:55.860 --> 00:22:00.100 +so any major mode inheriting prog-mode-- + +00:22:00.100 --> 00:22:02.233 +M-q will now by default be bound + +00:22:02.266 --> 00:22:09.779 +to prog-fill-reindent-defun. To summarize the point, + +00:22:09.780 --> 00:22:13.433 +if you are editing a string or a comment, + +00:22:13.466 --> 00:22:16.039 +then the comment will be filled. + +00:22:16.040 --> 00:22:19.100 +But if you are outside of a comment or outside of a string, + +00:22:19.100 --> 00:22:23.166 +then the defun or the top-level construct + +00:22:23.200 --> 00:22:26.159 +in the programming language will be re-indented. + +00:22:26.160 --> 00:22:34.099 +Let's try that out with maybe some file I have open here. + +00:22:34.100 --> 00:22:38.800 +If I'm in this... Let's choose some function, + +00:22:38.833 --> 00:22:40.733 +let's take this for example. + +00:22:40.766 --> 00:22:43.959 +If we followed all of this again, + +00:22:43.960 --> 00:22:47.400 +and I press M-q in on this paragraph, + +00:22:47.433 --> 00:22:49.433 +then the paragraph gets re-indented. + +00:22:49.466 --> 00:22:55.800 +But if I'm down here and I choose to break the indentation + +00:22:55.833 --> 00:22:58.166 +and then press M-q, + +00:22:58.200 --> 00:23:02.333 +then as you see, it practically selected the defun + +00:23:02.366 --> 00:23:03.566 +and re-indented everything + +00:23:03.600 --> 00:23:06.959 +without having me to move the point around in the buffer. + +00:23:06.960 --> 00:23:08.633 +So I think that's a really nice feature, + +00:23:08.666 --> 00:23:11.100 +which a lot of people can appreciate. + +00:23:11.100 --> 00:23:17.939 +It's one of those niceties which comes from time to time. + +NOTE Wrapping up + +00:23:17.940 --> 00:23:20.633 +Right, so that was my overview + +00:23:20.666 --> 00:23:22.600 +of what's going to be new in Emacs 30. + +00:23:22.633 --> 00:23:24.400 +I hope that most people could take away + +00:23:24.433 --> 00:23:25.579 +something from this presentation + +00:23:25.580 --> 00:23:28.900 +and have something to look forward + +00:23:28.900 --> 00:23:31.133 +to try out after upgrading. + +00:23:31.166 --> 00:23:33.833 +As mentioned initially, as of recording, + +00:23:33.866 --> 00:23:36.566 +this release has not been completed yet. + +00:23:36.600 --> 00:23:38.833 +If this is still not the case + +00:23:38.866 --> 00:23:40.233 +when you're seeing this video, + +00:23:40.266 --> 00:23:43.833 +please consider downloading and building Emacs 30 yourself. + +00:23:43.866 --> 00:23:48.200 +If you have any issues, which is always the case, + +00:23:48.233 --> 00:23:56.439 +please report them to using report-emacs-bug. + +00:23:56.440 --> 00:23:57.907 +That will pop up a mail buffer, + +00:23:57.908 --> 00:23:59.600 +and then you can describe your issue and send them out. + +00:23:59.633 --> 00:24:01.800 +All bug reports are valuable, + +00:24:01.833 --> 00:24:04.433 +even if they are false positives or duplicates-- + +00:24:04.466 --> 00:24:05.233 +it doesn't matter-- + +00:24:05.266 --> 00:24:08.533 +because when you take the time to submit a bug report, + +00:24:08.566 --> 00:24:12.233 +which describes something that's specific to your setup, + +00:24:12.266 --> 00:24:16.700 +which the developers might not have noticed or known about, + +00:24:16.700 --> 00:24:19.133 +then you are certainly helping out a lot of other people + +00:24:19.166 --> 00:24:21.766 +which might run into the same issue in the future. + +00:24:21.800 --> 00:24:23.200 +Especially with upgrades, + +00:24:23.233 --> 00:24:26.566 +it would be nice to figure out small problems + +00:24:26.600 --> 00:24:30.800 +which make upgrading difficult for some people. + +00:24:30.833 --> 00:24:34.700 +The ideal is, of course, to have no issues + +00:24:34.700 --> 00:24:37.199 +when upgrading from one version to another. + +00:24:37.200 --> 00:24:39.566 +Having said that, I thank you for your attention, + +00:24:39.600 --> 00:24:43.766 +and I'm saying goodbye. diff --git a/2024/info/emacs30-after.md b/2024/info/emacs30-after.md index c854e4a5..449fadd2 100644 --- a/2024/info/emacs30-after.md +++
