To make it short, + +00:05:12.120 --> 00:05:14.600 +Guix is another functional package manager, + +00:05:14.600 --> 00:05:21.840 +but more freedom- and reproducibility-oriented, + +00:05:21.840 --> 00:05:24.200 +and written in only one language (Guile Scheme) + +00:05:24.200 --> 00:05:29.880 +instead of few custom-made Nix DSL, Bash, and C++. + +00:05:29.880 --> 00:05:34.240 +So now I can write Lisp code, while this code + +00:05:34.240 --> 00:05:37.040 +writes another Lisp code. Very neat indeed. + +00:05:37.040 --> 00:05:42.760 +Unfortunately, at the moment, there was no tool + +00:05:42.760 --> 00:05:45.400 +to manage user configurations, + +00:05:45.400 --> 00:05:48.400 +also known as dotfiles, with Guix. + +00:05:48.400 --> 00:05:52.680 +So I wrote one. And now it's a part of GNU Guix + +00:05:52.680 --> 00:05:54.160 +and called Guix Home. + +00:05:54.160 --> 00:05:58.840 +What do we get from this one tool? + +00:05:58.840 --> 00:06:05.240 +We can use one language to describe the whole system, + +00:06:05.240 --> 00:06:09.080 +the home environment, the project environment, + +00:06:09.080 --> 00:06:10.240 +and everything else. + +00:06:10.240 --> 00:06:13.000 +We don't need to worry about + +00:06:13.000 --> 00:06:17.000 +to keep different tools in sync + +00:06:17.000 --> 00:06:19.760 +and to integrate them between each other. + +00:06:19.760 --> 00:06:23.080 +Also, using one language to describe + +00:06:23.080 --> 00:06:25.440 +the whole configuration makes it possible + +00:06:25.440 --> 00:06:28.640 +to share values between different parts of the system. + +00:06:28.640 --> 00:06:32.920 +For example, color scheme, fonts, and much more. + +00:06:32.920 --> 00:06:39.440 +To sum up the first part of the talk: + +00:06:39.440 --> 00:06:43.320 +I want a working environment which is ready for work, + +00:06:43.320 --> 00:06:47.960 +configured in minutes to almost what I want. + +00:06:47.960 --> 00:06:50.800 +That means it should have some batteries included. + +00:06:50.800 --> 00:06:52.000 +It should be reliable. + +00:06:52.000 --> 00:06:54.840 +I want to get back to work in seconds + +00:06:54.840 --> 00:06:56.160 +even if I broke something + +00:06:56.160 --> 00:06:58.200 +or someone else broke something. + +00:06:58.200 --> 00:07:03.560 +For example, using rollbacks. + +00:07:03.560 --> 00:07:07.320 +It would be nice if it will be performant. + +00:07:07.320 --> 00:07:08.640 +It's a little subjective thing, + +00:07:08.640 --> 00:07:12.360 +but it's nice when things are snappy. + +00:07:12.360 --> 00:07:16.160 +And it's cool when things are consistent. + +00:07:16.160 --> 00:07:17.800 +Different interfaces have + +00:07:17.800 --> 00:07:20.360 +the same way of interactions with them. + +00:07:20.360 --> 00:07:25.920 +Let's get to the next part, + +00:07:25.920 --> 00:07:29.120 +and let's discuss what rde is. + +00:07:29.120 --> 00:07:33.360 +Originally it was my dotfiles repo, + +00:07:33.360 --> 00:07:35.720 +but it grew into something bigger. + +00:07:35.720 --> 00:07:39.320 +Now, it's a set of tools on top of + +00:07:39.320 --> 00:07:41.680 +GNU Guix, Guix System, and Guix Home. + +00:07:41.680 --> 00:07:45.800 +You can treat it as a GNU/Linux distribution, + +00:07:45.800 --> 00:07:48.720 +system and home environment manager + +00:07:48.720 --> 00:07:50.880 +or configuration framework, + +00:07:50.880 --> 00:07:52.920 +project environment manager + +00:07:52.920 --> 00:07:55.160 +(like virtualenv, but on steroids), + +00:07:55.160 --> 00:07:58.200 +and Emacs distribution. + +00:07:58.200 --> 00:08:02.840 +Usually, you just pick a few features, + +00:08:02.840 --> 00:08:05.654 +parameterize them and ask the tool + +00:08:05.655 --> 00:08:08.120 +to create an operating system for you, + +00:08:08.120 --> 00:08:10.280 +a home environment, project environment, + +00:08:10.280 --> 00:08:11.560 +or Emacs configuration. + +00:08:11.560 --> 00:08:15.520 +That's it. That's simple. + +00:08:15.520 --> 00:08:22.080 +And what rde Emacs is and how it tastes... + +00:08:22.080 --> 00:08:26.360 +It's like an ice cream, vanilla-flavored. + +00:08:26.360 --> 00:08:30.880 +No fancy macros for configuration, just plain Elisp. + +00:08:30.880 --> 00:08:34.954 +You can find in almost every + +00:08:34.955 --> 00:08:36.480 +personal Emacs configuration, + +00:08:36.480 --> 00:08:42.640 +built-in or vanilla-flavored packages + +00:08:42.640 --> 00:08:45.588 +are in priority over external + +00:08:45.589 --> 00:08:46.760 +or very fancy packages. + +00:08:46.760 --> 00:08:52.200 +There is practical reason for this. + +00:08:52.200 --> 00:08:55.454 +Maybe sometimes you don't get the things + +00:08:55.455 --> 00:08:57.720 +you're used to in other text editors, + +00:08:57.720 --> 00:09:01.920 +or maybe even in other Emacs frameworks, + +00:09:01.920 --> 00:09:05.880 +but we want to keep the final result consistent, + +00:09:05.880 --> 00:09:08.720 +so you can apply the same interaction patterns + +00:09:08.720 --> 00:09:13.480 +in different situations and extend your expectations + +00:09:13.480 --> 00:09:15.000 +from one tool to another, + +00:09:15.000 --> 00:09:16.560 +from one package to another. + +00:09:16.560 --> 00:09:19.400 +For example, we encourage people + +00:09:19.400 --> 00:09:22.600 +to use the minibuffer completion + +00:09:22.600 --> 00:09:26.720 +with orderless and vertico for many tasks: + +00:09:26.720 --> 00:09:30.680 +code navigation, file navigation, + +00:09:30.680 --> 00:09:32.120 +looking through your emails, + +00:09:32.120 --> 00:09:35.160 +or just for jumping around. + +00:09:35.160 --> 00:09:36.320 +Let's see. + +00:09:36.320 --> 00:09:39.480 +First, create a new Emacs instance + +00:09:39.480 --> 00:09:45.280 +and open a repository with my configuration. + +00:09:45.280 --> 00:09:54.040 +You can see the source code. + +00:09:54.040 --> 00:09:58.760 +Let's open another file which contains + +00:09:58.760 --> 00:09:59.960 +Emacs-related features. + +00:09:59.960 --> 00:10:02.280 +You can see I use imenu, + +00:10:02.280 --> 00:10:08.360 +and I can filter the list using minibuffer. + +00:10:08.360 --> 00:10:16.600 +Now let's open the Magit interface, + +00:10:16.600 --> 00:10:18.920 +and now I want to navigate through + +00:10:18.920 --> 00:10:22.240 +this long list of things here. + +00:10:22.240 --> 00:10:25.560 +Some of them staged. Some of them are recent commits. + +00:10:25.560 --> 00:10:28.400 +Some of them are untracked at all. + +00:10:28.400 --> 00:10:31.040 +I can open imenu: the same interface, + +00:10:31.040 --> 00:10:34.640 +but for now, I can navigate around + +00:10:34.640 --> 00:10:41.320 +the Magit sections and files which are present here. + +00:10:41.320 --> 00:10:45.120 +If I want to navigate project files, + +00:10:45.120 --> 00:10:47.520 +I use almost the same interface. + +00:10:47.520 --> 00:10:51.720 +I can use the same patterns to filter out + +00:10:51.720 --> 00:11:00.400 +files in my project or items in magit-imenu. + +00:11:00.400 --> 00:11:07.720 +Very similar and very consistent. + +00:11:07.720 --> 00:11:11.920 +Also, we try to have hotkeys consistent + +00:11:11.920 --> 00:11:16.680 +across different packages and parts of Emacs. + +00:11:16.680 --> 00:11:21.720 +We usually don't provide alternatives on what to use. + +00:11:21.720 --> 00:11:25.520 +We provide only one package for one task. + +00:11:25.520 --> 00:11:28.154 +But of course this is + +00:11:28.155 --> 00:11:29.880 +a configuration framework after all. + +00:11:29.880 --> 00:11:32.800 +You can declare your own features, + +00:11:32.800 --> 00:11:35.788 +implement them yourself, + +00:11:35.789 --> 00:11:37.440 +and use whatever you want. + +00:11:37.440 --> 00:11:45.240 +Let's get to some real-world examples. + +00:11:45.240 --> 00:11:48.221 +It's always easy to show + +00:11:48.222 --> 00:11:50.200 +how things get appended, + +00:11:50.200 --> 00:11:51.760 +how things get installed, + +00:11:51.760 --> 00:11:55.288 +but usually people don't show + +00:11:55.289 --> 00:11:56.360 +how they remove things, + +00:11:56.360 --> 00:11:58.800 +because it's usually painful. + +00:11:58.800 --> 00:12:02.120 +But in our case, it's not. + +00:12:02.120 --> 00:12:10.840 +Let's take my configuration, + +00:12:10.840 --> 00:12:12.960 +let's find feature-emacs-vertico. + +00:12:12.960 --> 00:12:19.821 +Vertico's just used to show + +00:12:19.822 --> 00:12:25.880 +this fancy completion UI + +00:12:25.880 --> 00:12:27.400 +that you can see here. + +00:12:27.400 --> 00:12:30.960 +If I disable this feature + +00:12:30.960 --> 00:12:43.080 +and rebuild my home environment, + +00:12:43.080 --> 00:12:46.360 +Emacs will lack this feature. + +00:12:46.360 --> 00:12:55.400 +It may take some time. It was quite fast, + +00:12:55.400 --> 00:13:00.400 +I didn't expect it. + +00:13:00.400 --> 00:13:02.880 +I have Emacs. As you can see here, + +00:13:02.880 --> 00:13:06.280 +now it doesn't have this completion UI anymore. + +00:13:06.280 --> 00:13:09.280 +I just commented it out, + +00:13:09.280 --> 00:13:13.320 +rebuilt my home environment, + +00:13:13.320 --> 00:13:15.600 +and this thing disappeared from Emacs. + +00:13:15.600 --> 00:13:19.960 +But what if I broke something? + +00:13:19.960 --> 00:13:28.440 +I just call guix home roll-back command + +00:13:28.440 --> 00:13:31.200 +and launch Emacs again, and you see + +00:13:31.200 --> 00:13:32.800 +now we have vertico back. + +00:13:32.800 --> 00:13:36.080 +Very good. + +00:13:36.080 --> 00:13:41.280 +Reliability is one of the most important qualities + +00:13:41.280 --> 00:13:43.920 +of working environment. + +00:13:43.920 --> 00:13:46.400 +We can always get back to + +00:13:46.400 --> 00:13:48.440 +the working state of our environment + +00:13:48.440 --> 00:13:52.520 +and be sure that we do the things we want. + +00:13:52.520 --> 00:13:57.720 +Now let's see another example. + +00:13:57.720 --> 00:13:59.960 +Here I have a mastodon, + +00:13:59.960 --> 00:14:03.600 +a post which contains a gemini link. + +00:14:03.600 --> 00:14:11.560 +I can click it, and you see it opens emacsclient, + +00:14:11.560 --> 00:14:14.480 +it renders this gemini capsule, + +00:14:14.480 --> 00:14:17.800 +and we can read all the posts of this guy. + +00:14:17.800 --> 00:14:21.000 +Very cool. + +00:14:21.000 --> 00:14:26.760 +But what if I go back to my configuration, + +00:14:26.760 --> 00:14:32.400 +we'll find a feature related to elpher, + +00:14:32.400 --> 00:14:36.080 +the application which handles gemini links, + +00:14:36.080 --> 00:14:38.320 +we'll comment it out, + +00:14:38.320 --> 00:14:41.720 +and we'll rebuild my home environment. + +00:14:41.720 --> 00:14:47.120 +What I expect here is that + +00:14:47.120 --> 00:14:48.440 +when I will be clicking the link, + +00:14:48.440 --> 00:15:02.320 +emacsclient won't pop up anymore. + +00:15:02.320 --> 00:15:02.720 +Cool. + +00:15:02.720 --> 00:15:06.600 +We rebuilt it and let's click the link. + +00:15:06.600 --> 00:15:08.360 +Now you see, it just opens another tab + +00:15:08.360 --> 00:15:10.760 +which doesn't do anything useful. + +00:15:10.760 --> 00:15:14.080 +Cool. + +00:15:14.080 --> 00:15:15.520 +Why it is important? + +00:15:15.520 --> 00:15:19.640 +It is important because every time + +00:15:19.640 --> 00:15:24.640 +you install something and you want to remove it, + +00:15:24.640 --> 00:15:29.320 +some parts depending on it can be broken. + +00:15:29.320 --> 00:15:31.840 +And also important in the other way around. + +00:15:31.840 --> 00:15:34.920 +Sometimes you want to install something, + +00:15:34.920 --> 00:15:36.640 +and it requires a few steps. + +00:15:36.640 --> 00:15:40.600 +For example, if you want to have + +00:15:40.600 --> 00:15:43.160 +a docker.el in your Emacs, + +00:15:43.160 --> 00:15:49.080 +you need not only docker.el itself + +00:15:49.080 --> 00:15:51.360 +and configuration for it, + +00:15:51.360 --> 00:15:55.240 +you also need to add your user to the docker group. + +00:15:55.240 --> 00:15:59.000 +But before it, you need to create this group, + +00:15:59.000 --> 00:16:00.454 +and you also need to + +00:16:00.455 --> 00:16:02.800 +define a system service and run it. + +00:16:02.800 --> 00:16:05.800 +Also you need to install docker package, + +00:16:05.800 --> 00:16:11.640 +docker-cli package, and containerd package. + +00:16:11.640 --> 00:16:15.440 +You can forget every of this small step, + +00:16:15.440 --> 00:16:20.480 +but if it in your declarative configuration + +00:16:20.480 --> 00:16:23.588 +in one place, and you just ask + +00:16:23.589 --> 00:16:27.821 +to enable this feature, each of those steps + +00:16:27.822 --> 00:16:30.880 +will be performed automatically. + +00:16:30.880 --> 00:16:33.200 +If you don't need docker anymore, + +00:16:33.200 --> 00:16:34.840 +you just disable the feature, + +00:16:34.840 --> 00:16:38.480 +and all the effect of all those steps + +00:16:38.480 --> 00:16:42.840 +will be removed from your system. + +00:16:42.840 --> 00:16:46.640 +I won't be showing it because it probably will + +00:16:46.640 --> 00:16:48.920 +take more time for reconfiguring, + +00:16:48.920 --> 00:16:54.400 +but you can experiment with it on your own. + +00:16:54.400 --> 00:17:00.840 +Let's do another interesting thing. + +00:17:00.840 --> 00:17:05.921 +Let's construct a small + +00:17:05.922 --> 00:17:07.720 +Emacs configuration from scratch. + +00:17:07.720 --> 00:17:10.920 +Who's this? + +00:17:10.920 --> 00:17:14.240 +I will open a file which contains only + +00:17:14.240 --> 00:17:18.720 +emacs-portable feature and feature-user-info. + +00:17:18.720 --> 00:17:21.120 +Now I will build an environment, + +00:17:21.120 --> 00:17:24.480 +and inside this environment, + +00:17:24.480 --> 00:17:26.640 +I will launch a new Emacs instance. + +00:17:26.640 --> 00:17:28.800 +As you see, it's very different + +00:17:28.800 --> 00:17:30.440 +from what you saw previously. + +00:17:30.440 --> 00:17:32.120 +And it's almost barebones. + +00:17:32.120 --> 00:17:39.520 +It doesn't contain anything + +00:17:39.520 --> 00:17:41.760 +except user-mail-address + +00:17:41.760 --> 00:17:45.080 +which is set to my mail address, + +00:17:45.080 --> 00:17:46.880 +and user-full-name. + +00:17:46.880 --> 00:17:50.760 +How it works: + +00:17:50.760 --> 00:17:54.000 +In feature-user-info, I define a few values. + +00:17:54.000 --> 00:18:01.120 +Those values are obtained by Emacs + +00:18:01.120 --> 00:18:03.280 +feature-emacs-portable + +00:18:03.280 --> 00:18:07.480 +and set inside Emacs configuration. + +00:18:07.480 --> 00:18:12.840 +But let's enable a few more features. + +00:18:12.840 --> 00:18:15.400 +I will do it in one go + +00:18:15.400 --> 00:18:22.120 +because we already saw how it works overall. + +00:18:22.120 --> 00:18:30.160 +Let's build another Emacs with Emacs configuration. + +00:18:30.160 --> 00:18:39.280 +The interesting thing about this Emacs instance + +00:18:39.280 --> 00:18:44.560 +is that it doesn't contain anything + +00:18:44.560 --> 00:18:46.520 +that I have in my usual Emacs. + +00:18:46.520 --> 00:18:49.360 +For example, I don't have much here. + +00:18:49.360 --> 00:18:55.040 +I don't have make installed, and so on. + +00:18:55.040 --> 00:19:06.640 +But we have feature-loader-portable package + +00:19:06.640 --> 00:19:09.960 +which just requires a few configure packages. + +00:19:09.960 --> 00:19:13.320 +Let's move it to a separate workspace. + +00:19:13.320 --> 00:19:21.680 +First of all, configure-rde-emacs-portable + +00:19:21.680 --> 00:19:23.720 +which just sets a few variables. + +00:19:23.720 --> 00:19:27.280 +rde configure-keycast which just shows + +00:19:27.280 --> 00:19:31.200 +something on the modeline + +00:19:31.200 --> 00:19:34.440 +which demonstrates the last hotkey pressed + +00:19:34.440 --> 00:19:40.080 +and the command which was invoked. + +00:19:40.080 --> 00:19:41.640 +We can enable which-key, + +00:19:41.640 --> 00:19:45.040 +and now when I type a prefix, + +00:19:45.040 --> 00:19:48.600 +I can see all the possible continuations + +00:19:48.600 --> 00:19:49.360 +for this prefix. + +00:19:49.360 --> 00:19:51.880 +I can enable vertico, + +00:19:51.880 --> 00:19:58.160 +and you can see, now we have nice completion UI. + +00:19:58.160 --> 00:20:03.560 +We can enable completion-related improvements + +00:20:03.560 --> 00:20:07.560 +and now I have not only UI itself, but also + +00:20:07.560 --> 00:20:15.320 +some notes here near each command, + +00:20:15.320 --> 00:20:17.800 +and ability to use regular expressions + +00:20:17.800 --> 00:20:21.480 +or some orderless matching. + +00:20:21.480 --> 00:20:26.400 +We can enable eshell, + +00:20:26.400 --> 00:20:31.320 +and now I have a hotkey for invoking Emacs shell. + +00:20:31.320 --> 00:20:35.920 +I don't have hotkey for vterm yet, + +00:20:35.920 --> 00:20:37.360 +but I can enable it, + +00:20:37.360 --> 00:20:40.800 +and now I have a terminal inside my Emacs. + +00:20:40.800 --> 00:20:43.240 +As you can see my usual shell is Zsh, + +00:20:43.240 --> 00:20:46.040 +but here I have a plain bash. + +00:20:46.040 --> 00:20:52.280 +Let's enable feature-git, + +00:20:52.280 --> 00:21:04.720 +and now I will be able to open my project. + +00:21:04.720 --> 00:21:11.488 +And inside this project, + +00:21:11.489 --> 00:21:14.640 +I will be able to open Magit + +00:21:14.640 --> 00:21:19.880 +and navigate around using imenu. + +00:21:19.880 --> 00:21:26.160 +Let's do few more things. + +00:21:26.160 --> 00:21:29.640 +Let's enable Org Roam + +00:21:29.640 --> 00:21:43.840 +so I will be able to open my EmacsConf notes. + +00:21:43.840 --> 00:21:48.240 +Let's enable configure-emacs. + +00:21:48.240 --> 00:21:53.320 +As you can see, the way it displayed updated. + +00:21:53.320 --> 00:21:59.520 +Let's enable configure-appearance, + +00:21:59.520 --> 00:22:03.880 +and you see the appearance of Emacs changed radically. + +00:22:03.880 --> 00:22:06.560 +And also, let's change the faces. + +00:22:06.560 --> 00:22:13.040 +And now you see almost my setup + +00:22:13.040 --> 00:22:14.800 +that you saw previously, + +00:22:14.800 --> 00:22:19.000 +but we build it from small tiny pieces. + +00:22:19.000 --> 00:22:27.520 +A little summary: + +00:22:27.520 --> 00:22:32.280 +rde is the one tool that you can use + +00:22:32.280 --> 00:22:34.440 +to manage the whole computing experience. + +00:22:34.440 --> 00:22:38.080 +It consists of composable components, + +00:22:38.080 --> 00:22:41.720 +and actually, it provides + +00:22:41.720 --> 00:22:43.240 +a reliable configuration framework. + +00:22:43.240 --> 00:22:46.360 +You always have a rollback. + +00:22:46.360 --> 00:22:49.320 +You always can switch to a generation + +00:22:49.320 --> 00:22:50.560 +you used a week ago. + +00:22:50.560 --> 00:22:57.520 +And of course, it's reproducible and declarative + +00:22:57.520 --> 00:22:58.680 +which is also very cool. + +00:22:58.680 --> 00:23:05.788 +rde Emacs is a part of rde + +00:23:05.789 --> 00:23:06.920 +but it can be used separately. + +00:23:06.920 --> 00:23:11.280 +You can think of it as an Emacs distribution + +00:23:11.280 --> 00:23:14.040 +which is vanilla-flavored, consistent, + +00:23:14.040 --> 00:23:15.960 +well-integrated, and self-contained. + +00:23:15.960 --> 00:23:19.560 +That's it for today. + +00:23:19.560 --> 00:23:22.054 +Don't hesitate to contact me + +00:23:22.055 --> 00:23:23.840 +via email or any other way. + +00:23:23.840 --> 00:23:28.154 +Thank you everyone for your attention + +00:23:28.155 --> 00:23:33.760 +and see you in a bit. |
