+WEBVTT captioned by sachac
+
+00:00:00.000 --> 00:00:11.480
+Hello and welcome everyone at EmacsConf 2022.
+
+00:00:11.480 --> 00:00:13.400
+I'm Andrew Tropin, and today
+
+00:00:13.400 --> 00:00:16.280
+we will talk about my Emacs setup.
+
+00:00:16.280 --> 00:00:19.360
+I will tell you the story behind it.
+
+00:00:19.360 --> 00:00:23.960
+We will discuss what rde and rde Emacs are,
+
+00:00:23.960 --> 00:00:28.760
+and we'll make a small Emacs configuration.
+
+00:00:28.760 --> 00:00:30.920
+My original motivation was to have
+
+00:00:30.920 --> 00:00:34.000
+a ready for work development environment
+
+00:00:34.000 --> 00:00:36.640
+which is reliable and guaranteed to work
+
+00:00:36.640 --> 00:00:37.840
+every time I need it,
+
+00:00:37.840 --> 00:00:42.680
+preferably performant and consistent.
+
+00:00:42.680 --> 00:00:44.160
+I say development environment,
+
+00:00:44.160 --> 00:00:45.720
+but it actually applies to
+
+00:00:45.720 --> 00:00:47.600
+many other working environment,
+
+00:00:47.600 --> 00:00:52.040
+especially text-heavy.
+
+00:00:52.040 --> 00:00:54.040
+An easy and obvious solution is to
+
+00:00:54.040 --> 00:00:57.640
+pick one of existing configuration frameworks
+
+00:00:57.640 --> 00:01:00.760
+like Spacemacs, Doom Emacs, Prelude,
+
+00:01:00.760 --> 00:01:02.520
+or something else,
+
+00:01:02.520 --> 00:01:05.040
+and to get a pre-configured Emacs
+
+00:01:05.040 --> 00:01:09.040
+in a minute with all bells and whistles.
+
+00:01:09.040 --> 00:01:12.480
+But the problem is: only Emacs.
+
+00:01:12.480 --> 00:01:16.400
+In reality, your working environment consists
+
+00:01:16.400 --> 00:01:18.680
+not only from elisp packages,
+
+00:01:18.680 --> 00:01:21.360
+but also from system packages
+
+00:01:21.360 --> 00:01:23.320
+and their configurations, project libraries,
+
+00:01:23.320 --> 00:01:27.080
+compilers, building tools, etc.,
+
+00:01:27.080 --> 00:01:31.600
+and thus you already have at least
+
+00:01:31.600 --> 00:01:34.880
+three, or more likely, five things
+
+00:01:34.880 --> 00:01:37.120
+for managing your environment:
+
+00:01:37.120 --> 00:01:39.640
+configuration, Emacs configuration framework,
+
+00:01:39.640 --> 00:01:42.880
+Emacs package manager, system package manager,
+
+00:01:42.880 --> 00:01:46.600
+system/dot files configuration manager,
+
+00:01:46.600 --> 00:01:49.080
+project/language package manager
+
+00:01:49.080 --> 00:01:51.800
+and maybe something else.
+
+00:01:51.800 --> 00:01:56.360
+Even having our Emacs configuration
+
+00:01:56.360 --> 00:01:59.800
+and package manager covered by framework
+
+00:01:59.800 --> 00:02:02.080
+we still have a lot of things
+
+00:02:02.080 --> 00:02:04.240
+which we have to interact with,
+
+00:02:04.240 --> 00:02:08.640
+keep in sync, and more importantly,
+
+00:02:08.640 --> 00:02:12.480
+each of them can break.
+
+00:02:12.480 --> 00:02:17.320
+But by "works every time," I mean
+
+00:02:17.320 --> 00:02:19.560
+even if I updated my system packages,
+
+00:02:19.560 --> 00:02:23.880
+configurations, I migrated to a different machine,
+
+00:02:23.880 --> 00:02:29.120
+someone on my team updated project dependencies,
+
+00:02:29.120 --> 00:02:31.960
+I can get back to work in a matter of seconds,
+
+00:02:31.960 --> 00:02:39.040
+or maybe in some cases, minutes.
+
+00:02:39.040 --> 00:02:40.400
+If I have multiple tools
+
+00:02:40.400 --> 00:02:43.720
+for managing my environment
+
+00:02:43.720 --> 00:02:45.720
+and even one of them is broken,
+
+00:02:45.720 --> 00:02:48.360
+the whole setup is broken.
+
+00:02:48.360 --> 00:02:51.080
+Also, if one of them doesn't support
+
+00:02:51.080 --> 00:02:53.560
+deterministic rollback,
+
+00:02:53.560 --> 00:02:58.200
+I can't guarantee the reliability
+
+00:02:58.200 --> 00:02:59.200
+of my working environment.
+
+00:02:59.200 --> 00:03:01.360
+I can't be sure that I will be able to
+
+00:03:01.360 --> 00:03:02.800
+rescue or revive it.
+
+00:03:02.800 --> 00:03:06.760
+The less points of failure we have,
+
+00:03:06.760 --> 00:03:09.720
+the easier to stay sane.
+
+00:03:09.720 --> 00:03:13.080
+Imagine some late breakage notice
+
+00:03:13.080 --> 00:03:17.880
+when you did update a few hours or days ago
+
+00:03:17.880 --> 00:03:20.920
+and found it later, and you have
+
+00:03:20.920 --> 00:03:25.320
+a few different tools involved.
+
+00:03:25.320 --> 00:03:28.280
+It will be really hard to find the cause
+
+00:03:28.280 --> 00:03:34.840
+and to make everything work again.
+
+00:03:34.840 --> 00:03:37.880
+Is it possible to have one tool
+
+00:03:37.880 --> 00:03:44.360
+to cover all the needs I described above?
+
+00:03:44.360 --> 00:03:48.520
+Yes, almost. With this tool,
+
+00:03:48.520 --> 00:03:50.320
+you can get a reliable setup.
+
+00:03:50.320 --> 00:03:57.400
+Now, I talk about functional package managers.
+
+00:03:57.400 --> 00:04:00.680
+Functional package managers allow us to
+
+00:04:00.680 --> 00:04:03.720
+manage systems, users, Emacs, project/
+
+00:04:03.720 --> 00:04:07.560
+language packages, and their configurations.
+
+00:04:07.560 --> 00:04:10.880
+But more importantly, it allows to do it
+
+00:04:10.880 --> 00:04:13.200
+in a declarative and reproducible manner.
+
+00:04:13.200 --> 00:04:16.840
+That means you just define what you need,
+
+00:04:16.840 --> 00:04:19.680
+and those tools build it for you.
+
+00:04:19.680 --> 00:04:24.320
+No matter what was before, you get what you asked for.
+
+00:04:24.320 --> 00:04:26.200
+It doesn't matter what time of day,
+
+00:04:26.200 --> 00:04:29.640
+what you did before, what other packages
+
+00:04:29.640 --> 00:04:31.680
+you have installed previously.
+
+00:04:31.680 --> 00:04:34.440
+You just ask for something, and you get it.
+
+00:04:34.440 --> 00:04:41.440
+Two years ago, I did a talk at EmacsConf 2020
+
+00:04:41.440 --> 00:04:43.840
+where I demonstrated a prototype of
+
+00:04:43.840 --> 00:04:47.480
+Emacs configuration managed by Nix.
+
+00:04:47.480 --> 00:04:50.480
+Originally, I wanted to base my work on
+
+00:04:50.480 --> 00:04:56.160
+an already existing Emacs configuration framework.
+
+00:04:56.160 --> 00:05:01.360
+But later, I decided that it will be easier
+
+00:05:01.360 --> 00:05:02.440
+and a little more flexible
+
+00:05:02.440 --> 00:05:04.920
+to start from ground up.
+
+00:05:04.920 --> 00:05:06.960
+After the first prototype in Nix,
+
+00:05:06.960 --> 00:05:12.120
+I decided to switch to Guix. 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.
