00:00.000 --> 00:01.783
Welcome to my talk "Emacs with Nyxt:

00:01.783 --> 00:02.823
extend your editor with

00:02.823 --> 00:04.623
the power of a Lisp browser".

00:04.623 --> 00:06.583
Who am I? I'm Andrea. I work as

00:06.583 --> 00:08.303
a Clojure software engineer somewhere

00:08.303 --> 00:09.743
in the middle of the UK.

00:09.743 --> 00:11.743
And I inherited my passion for Emacs

00:11.743 --> 00:13.703
from my Ph.D. supervisor, and from that

00:13.703 --> 00:15.943
moment on Emacs became a core tool

00:15.943 --> 00:17.863
of my daily routine.

00:17.863 --> 00:20.863
You can find more about me and my interests

00:20.863 --> 00:23.983
at ag91.github.io, that is my blog.

00:23.983 --> 00:25.183
Let's get into the talk.

00:25.183 --> 00:28.183
So, why Nyxt? Nyxt is an extensible

00:28.183 --> 00:29.543
Common Lisp browser.

00:29.543 --> 00:31.903
Fundamentally, it's Emacs for web browsing.

00:31.903 --> 00:34.063
And why do I say that? I say that

00:34.063 --> 00:36.063
because is a…, this is Nyxt.

00:36.063 --> 00:40.223
You can see that is organized with buffers,

00:40.223 --> 00:44.063
and you can see that I can invoke command,

00:44.063 --> 00:47.183
like, I was in Emacs with this.

00:47.183 --> 00:48.983
So, I'm using even the same keybindings,

00:48.983 --> 00:52.783
so, for that I used M-x.

00:52.783 --> 00:55.983
And some of the features of Nyxt

00:55.983 --> 01:00.103
are just amazing. For example, say that

01:00.103 --> 01:03.823
you want to mark some text, this is the way,

01:03.823 --> 01:08.703
so, I just pressed Control space (C-SPC),

01:08.703 --> 01:10.423
and now I will start the marker,

01:10.423 --> 01:13.223
and now I can copy the text, and when

01:13.223 --> 01:15.663
I'm done, I can finish to use visual mode.

01:15.663 --> 01:18.023
Or, for example, what about…,

01:18.023 --> 01:21.183
I want to navigate without using my mouse.

01:21.183 --> 01:25.183
I can do something like follow-hint,

01:25.183 --> 01:28.023
and this opens the possibility to press

01:28.023 --> 01:29.903
AC to jump on the Articles,

01:29.903 --> 01:33.063
and all of a sudden I'm on the page

01:33.063 --> 01:36.023
with the blog posts of the Atlas team.

01:36.023 --> 01:39.383
Or, for example, I can extend my browser

01:39.383 --> 01:40.783
from within the browser.

01:40.783 --> 01:43.223
So, you can see I can evaluate a command,

01:43.223 --> 01:48.663
a Common Lisp code,

01:48.663 --> 01:50.903
and it produces the result.

01:50.903 --> 01:56.183
And then, for example, I can also auto….

01:56.183 --> 01:58.663
This browser comes by default with an

01:58.663 --> 02:01.143
integration with your password manager,

02:01.143 --> 02:04.223
in my case it's pass, and I can copy

02:04.223 --> 02:08.783
a password. This is just as easy as is,

02:08.783 --> 02:10.543
it comes by default.

02:10.543 --> 02:13.583
Another incredibly useful feature

02:13.583 --> 02:18.023
that I didn't find in other browsers is

02:18.023 --> 02:20.503
searching between multiple buffers.

02:20.503 --> 02:23.503
So, this function search-buffers,

02:23.503 --> 02:25.823
this command lets me select

02:25.823 --> 02:29.503
some of my open buffers,

02:29.503 --> 02:32.503
and I can look for a string in there.

02:32.503 --> 02:34.623
And you would see that the hits are

02:34.623 --> 02:37.423
from the buffers that I have open,

02:37.423 --> 02:42.583
for example, Clojure or

02:42.583 --> 02:46.103
the YouTube video about Clojure.

02:46.103 --> 02:49.623
Let me get into something very interesting.

02:49.623 --> 02:52.783
How can I make Emacs speak to Nyxt.

02:52.783 --> 02:55.103
And for that, let me show you something

02:55.103 --> 02:57.143
in the literate programming approach.

02:57.143 --> 03:00.183
So, this Org mode source block is

03:00.183 --> 03:04.423
linked to this Nyxt REPL.

03:04.423 --> 03:06.983
I can define a new command,

03:06.983 --> 03:09.343
and when I go in Nyxt,

03:09.343 --> 03:10.863
I can find this new command,

03:10.863 --> 03:12.503
and I can invoke it, and you can see

03:12.503 --> 03:16.943
there is something in the minibuffer.

03:16.943 --> 03:21.543
I can use it from Nyxt, but I can do it here.

03:21.543 --> 03:24.703
I can also use it directly from the REPL.

03:24.703 --> 03:27.743
You can see that the same thing is logged

03:27.743 --> 03:30.423
in the REPL.

03:30.423 --> 03:32.663
And then with something that I would speak

03:32.663 --> 03:36.423
about in another talk in the conference

03:36.423 --> 03:39.143
— Moldable Emacs. I can also just

03:39.143 --> 03:42.823
evaluate JavaScript outside. Let's create

03:42.823 --> 03:46.703
a playground that allows me to write some

03:46.703 --> 03:49.903
JavaScript code. And if I evaluate this code,

03:49.903 --> 03:52.023
I get the title of the webpage

03:52.023 --> 03:54.583
that is currently open in Nyxt.

03:54.583 --> 03:58.343
The cool thing is that I can do it also

03:58.343 --> 04:02.263
directly in Lisp, this is Parenscript

04:02.263 --> 04:05.223
that evaluates to the same thing,

04:05.223 --> 04:07.823
(it) is just the same, just document.title,

04:07.823 --> 04:10.743
only that is in Common Lisp.

04:10.743 --> 04:14.343
You see that Emacs can speak to Nyxt,

04:14.343 --> 04:16.103
but also the reverse is true.

04:16.103 --> 04:19.023
Nyxt can speak to Emacs. So, for example,

04:19.023 --> 04:21.943
if I'm in Nyxt, and for example,

04:21.943 --> 04:26.623
let me go to my blog, if I press here,

04:26.623 --> 04:30.863
this is an email link, automatically in Emacs

04:30.863 --> 04:33.943
it will let me compone a message

04:33.943 --> 04:35.943
using my email manager.

04:35.943 --> 04:39.823
Or, say that always in my blog I want

04:39.823 --> 04:43.543
to write something here in the searchbar,

04:43.543 --> 04:46.303
I think that I don't want to write it in

04:46.303 --> 04:50.623
the browser but in my Emacs because

04:50.623 --> 04:52.903
I have some template for search.

04:52.903 --> 04:55.503
If I do this, all of a sudden

04:55.503 --> 04:59.103
the text is added.

04:59.103 --> 05:03.423
Or say I'm watching that Clojure video,

05:03.423 --> 05:06.343
and I get to this point, and then I say

05:06.343 --> 05:09.703
"Yuu! This is a very interesting thing,

05:09.703 --> 05:12.783
let me take a note". So, I take some note

05:12.783 --> 05:16.903
with some text, and if I go back in Emacs,

05:16.903 --> 05:19.023
tadam! I found the note,

05:19.023 --> 05:21.903
and I found it with the duration,

05:21.903 --> 05:25.063
so I can just jump to the same point.

05:25.063 --> 05:28.743
And what else?

05:28.743 --> 05:31.903
There is something even bigger

05:31.903 --> 05:32.663
that we can do,

05:32.663 --> 05:34.063
this is a bit more advanced,

05:34.063 --> 05:35.823
and this is something that I do

05:35.823 --> 05:39.023
again with my Moldable Emacs.

05:39.023 --> 05:41.183
Say that you want to do some

05:41.183 --> 05:43.223
data visualization.

05:43.223 --> 05:44.863
If we use Vega-Lite…, for example,

05:44.863 --> 05:47.823
we want to visualize a scatter plot.

05:47.823 --> 05:49.623
Let me take some example data

05:49.623 --> 05:52.423
that could be interesting also to you.

05:52.423 --> 05:55.063
So, say that I have this playground

05:55.063 --> 05:57.263
that lets me evaluate

05:57.263 --> 06:01.703
some query on my Org-roam database.

06:01.703 --> 06:03.663
What I'm doing here is I'm gonna

06:03.663 --> 06:05.703
go through my first 100 notes

06:05.703 --> 06:09.823
and collect their backlinks,

06:09.823 --> 06:13.183
so some information that I find interesting.

06:13.183 --> 06:16.343
If I convert this to JSON,

06:16.343 --> 06:18.903
now, all of a sudden this is something

06:18.903 --> 06:22.623
that I can put in that Vega-Lite template

06:22.623 --> 06:26.183
that I showed you a moment ago.

06:26.183 --> 06:28.343
So, I'm gonna find out that file,

06:28.343 --> 06:30.463
you see that I left a question mark,

06:30.463 --> 06:31.703
(this is) something that I still

06:31.703 --> 06:33.783
didn't automate completely.

06:33.783 --> 06:37.983
By saving this file and opening it with Nyxt,

06:37.983 --> 06:41.183
you can see that now I have a scatter plot.

06:41.183 --> 06:43.943
And these are my actual notes,

06:43.943 --> 06:48.343
so you can see that if I stay on it,

06:48.343 --> 06:53.063
these are actually my notes.

06:53.063 --> 06:55.343
When I'm in Emacs, what I can do is

06:55.343 --> 06:58.303
I click here, and now in the background

06:58.303 --> 07:00.903
it opened my note,

07:00.903 --> 07:04.303
and it opened with all my backlinks.

07:04.303 --> 07:07.703
You can see that I have embedded in my

07:07.703 --> 07:11.303
browser some functionality of Emacs.

07:11.303 --> 07:13.463
You understand that this is the power of

07:13.463 --> 07:16.983
unifying, integrating these two experiences,

07:16.983 --> 07:18.943
and it opens the doors for

07:18.943 --> 07:22.223
a lot of interesting interactivity.

07:22.223 --> 07:24.743
Anyway, what is next?

07:24.743 --> 07:29.023
This was my talk, what is next is

07:29.023 --> 07:32.143
continue merging it with Moldable Emacs.

07:32.143 --> 07:34.023
(This) is something I will present in

07:34.023 --> 07:37.463
another talk in this conference with web,

07:37.463 --> 07:39.263
so that we can extract meaning from

07:39.263 --> 07:41.103
the web, and we can bring it in Emacs.

07:41.103 --> 07:43.583
And from Emacs bringing back stuff

07:43.583 --> 07:46.543
like a picture into a web page,

07:46.543 --> 07:48.903
so that we can do fancy visualization.

07:48.903 --> 07:51.063
Another thing I want to do is to

07:51.063 --> 07:54.263
automate the boring browser flows

07:54.263 --> 07:55.543
that I do, like, for example,

07:55.543 --> 07:58.263
if I periodically buy something,

07:58.263 --> 08:00.863
I could do it from within Emacs

08:00.863 --> 08:05.263
instead of always clicking around.

08:05.263 --> 08:08.383
And then I'm just gonna cross fingers,

08:08.383 --> 08:10.023
I hope that this browser will

08:10.023 --> 08:11.783
become mainstream.

08:11.783 --> 08:13.263
So, this was my talk,

08:13.263 --> 08:14.663
thank you for listening,

08:14.663 --> 08:17.343
and you can find more about it at

08:17.343 --> 08:19.823
ag91.github.io, my blog,

08:19.823 --> 08:22.680
and enjoy the rest of the conference, bye!
