00:00:38.640 --> 00:00:41.120
way uh but but I'm talking about special

00:00:41.120 --> 00:00:42.239
blocks and if I

00:00:42.239 --> 00:00:45.039
show you an emax then I have to export

00:00:45.039 --> 00:00:47.039
the html so you can see what it looks

00:00:47.039 --> 00:00:47.840
like

00:00:47.840 --> 00:00:50.800
or export to a pdf so you can see what

00:00:50.800 --> 00:00:51.920
it looks like

00:00:51.920 --> 00:00:54.239
uh so I ended up writing an org reveal

00:00:54.239 --> 00:00:56.399
and

00:00:56.399 --> 00:00:58.960
joyously this this just works you can

00:00:58.960 --> 00:01:00.879
you can just see things here

00:01:00.879 --> 00:01:02.960
uh I was worried that I'd have to take

00:01:02.960 --> 00:01:04.559
pictures and then you know

00:01:04.559 --> 00:01:07.600
uh uh you know insert pings so that that

00:01:07.600 --> 00:01:09.760
was a delight

00:01:09.760 --> 00:01:12.159
okay uh so special blocks are these

00:01:12.159 --> 00:01:12.960
things like

00:01:12.960 --> 00:01:16.000
a center small quote uh that's what a

00:01:16.000 --> 00:01:17.280
special block is

00:01:17.280 --> 00:01:19.360
and with a bit of lisp we can we can

00:01:19.360 --> 00:01:20.720
make special blocks

00:01:20.720 --> 00:01:23.200
and link types right so uh using a

00:01:23.200 --> 00:01:24.799
single interface

00:01:24.799 --> 00:01:26.720
um and the interface is going to be

00:01:26.720 --> 00:01:27.840
similar to one

00:01:27.840 --> 00:01:29.439
many people are familiar with in

00:01:29.439 --> 00:01:32.560
particular org babel's

00:01:32.560 --> 00:01:35.840
source interface as well as using global

00:01:35.840 --> 00:01:37.840
header arguments for link types

00:01:37.840 --> 00:01:39.680
and the idea is to write it once and

00:01:39.680 --> 00:01:41.200
generate many different kinds

00:01:41.200 --> 00:01:44.159
right you write uh an org markup and you

00:01:44.159 --> 00:01:44.720
can have

00:01:44.720 --> 00:01:47.680
uh html you can have pdf and and

00:01:47.680 --> 00:01:48.560
joyously

00:01:48.560 --> 00:01:51.840
uh org reveal so that was uh that was an

00:01:51.840 --> 00:01:53.600
unexpected delight

00:01:53.600 --> 00:01:56.640
um so here is a few that you'll you'll

00:01:56.640 --> 00:01:57.840
just see as we

00:01:57.840 --> 00:02:01.759
uh in this presentation you know some uh

00:02:01.759 --> 00:02:04.000
uh I won't show some of these uh link

00:02:04.000 --> 00:02:05.040
only ones

00:02:05.040 --> 00:02:06.799
but we'll see a few of these other ones

00:02:06.799 --> 00:02:08.080
just to make the uh

00:02:08.080 --> 00:02:09.920
presentation look nice so the

00:02:09.920 --> 00:02:11.520
presentation is really going to

00:02:11.520 --> 00:02:14.000
present these blocks and the mechanism

00:02:14.000 --> 00:02:15.120
at the same time

00:02:15.120 --> 00:02:18.400
so uh so this no no html was written

00:02:18.400 --> 00:02:21.280
look ma no html just pure org mode and

00:02:21.280 --> 00:02:22.000
and

00:02:22.000 --> 00:02:23.520
you get all these beautiful boxes and

00:02:23.520 --> 00:02:25.840
things okay

00:02:25.840 --> 00:02:27.680
so the motivation for this is you know

00:02:27.680 --> 00:02:29.120
what uh

00:02:29.120 --> 00:02:31.200
you're you're online you run into a blog

00:02:31.200 --> 00:02:32.239
and you see something you like and

00:02:32.239 --> 00:02:33.120
you're like man

00:02:33.120 --> 00:02:35.280
you know I wish I could uh you know

00:02:35.280 --> 00:02:36.640
produce that

00:02:36.640 --> 00:02:39.519
um uh but you you check in the author

00:02:39.519 --> 00:02:40.160
wrote raw

00:02:40.160 --> 00:02:44.239
html you know plus html everywhere

00:02:44.239 --> 00:02:46.800
and uh that's that's you know gonna

00:02:46.800 --> 00:02:47.840
obscure

00:02:47.840 --> 00:02:49.680
your your real content it's going to be

00:02:49.680 --> 00:02:51.200
surrounded by all this uh

00:02:51.200 --> 00:02:54.239
styling information that's unfortunate

00:02:54.239 --> 00:02:56.400
uh the author decides to use an org

00:02:56.400 --> 00:02:58.959
macro all right a bit better

00:02:58.959 --> 00:03:01.120
but then what if you decide hey I want

00:03:01.120 --> 00:03:03.360
to make a

00:03:03.360 --> 00:03:06.000
not pdf great and then the worst of all

00:03:06.000 --> 00:03:07.840
the author doesn't give you the source

00:03:07.840 --> 00:03:10.159
and then you have to view page source

00:03:10.159 --> 00:03:10.879
and

00:03:10.879 --> 00:03:13.760
learn cascading style sheets and and you

00:03:13.760 --> 00:03:14.239
know

00:03:14.239 --> 00:03:16.159
sit in a corner and cry decide to do

00:03:16.159 --> 00:03:18.080
other things with your life

00:03:18.080 --> 00:03:20.959
so uh we want to give you org users

00:03:20.959 --> 00:03:22.640
numerous styles

00:03:22.640 --> 00:03:26.000
and uh and an extensible mechanism to

00:03:26.000 --> 00:03:27.200
add more of these

00:03:27.200 --> 00:03:28.799
aesthetically pleasing styles you know

00:03:28.799 --> 00:03:31.200
to have really nice things

00:03:31.200 --> 00:03:34.720
look one way in the html and look almost

00:03:34.720 --> 00:03:35.599
the same way

00:03:35.599 --> 00:03:39.120
in the pdf and other uh back ends and

00:03:39.120 --> 00:03:41.680
if by having these newer ones you know

00:03:41.680 --> 00:03:42.159
people

00:03:42.159 --> 00:03:44.879
might be encouraged to try making new

00:03:44.879 --> 00:03:45.519
ones

00:03:45.519 --> 00:03:47.920
especially when the interface is uh not

00:03:47.920 --> 00:03:49.040
so difficult

00:03:49.040 --> 00:03:54.159
uh that's the that's the aim okay

00:03:54.159 --> 00:03:57.360
uh so let's let's have a a real story to

00:03:57.360 --> 00:03:59.120
motivate this even more

00:03:59.120 --> 00:04:02.319
um so here's three friends uh I hope I

00:04:02.319 --> 00:04:03.599
don't butcher their names but these

00:04:03.599 --> 00:04:04.640
friends are called

00:04:04.640 --> 00:04:07.040
amin sasha and corwin and then they're

00:04:07.040 --> 00:04:08.720
organizing a conference

00:04:08.720 --> 00:04:12.080
uh EmacsConf 2020.

00:04:12.080 --> 00:04:14.239
so sasha decides to write an org file

00:04:14.239 --> 00:04:16.479
and and she would like some feedback

00:04:16.479 --> 00:04:19.199
okay and and just uh make it clear

00:04:19.199 --> 00:04:19.840
there's no

00:04:19.840 --> 00:04:22.960
uh just how easy this looks

00:04:22.960 --> 00:04:27.280
let's look at the source for this block

00:04:27.280 --> 00:04:30.000
notice it's just the word green then a

00:04:30.000 --> 00:04:30.720
colon

00:04:30.720 --> 00:04:34.560
than amine uh so no

00:04:34.560 --> 00:04:37.759
no div style coloring just just you know

00:04:37.759 --> 00:04:38.479
green color

00:04:38.479 --> 00:04:41.520
immune a very pleasant uh or markup

00:04:41.520 --> 00:04:43.600
so that's that's quite nice put some

00:04:43.600 --> 00:04:44.960
bold around it

00:04:44.960 --> 00:04:47.840
not not too difficult so hopefully uh

00:04:47.840 --> 00:04:49.040
this will be useful to

00:04:49.040 --> 00:04:51.680
other people as well so what kind of

00:04:51.680 --> 00:04:52.240
feedback

00:04:52.240 --> 00:04:56.639
uh would sasha expect to get um so maybe

00:04:56.639 --> 00:04:59.120
she would expect top level remarks

00:04:59.120 --> 00:04:59.680
visible

00:04:59.680 --> 00:05:01.759
in the export you know when she makes an

00:05:01.759 --> 00:05:04.400
html she can see right there a big block

00:05:04.400 --> 00:05:07.840
right maybe

00:05:07.840 --> 00:05:09.840
amin will suggest to sasha please

00:05:09.840 --> 00:05:11.120
replace this part

00:05:11.120 --> 00:05:12.960
with this other part or replace this

00:05:12.960 --> 00:05:14.639
word with this other word

00:05:14.639 --> 00:05:16.960
right um this is not really possible

00:05:16.960 --> 00:05:17.680
with raw

00:05:17.680 --> 00:05:21.919
html or uh yeah or with even latex

00:05:21.919 --> 00:05:24.000
you'd have to have multiple arguments

00:05:24.000 --> 00:05:25.360
the first argument and then

00:05:25.360 --> 00:05:27.840
the replacement argument and it's a bit

00:05:27.840 --> 00:05:28.800
clunky

00:05:28.800 --> 00:05:30.960
um but with our setup you just write

00:05:30.960 --> 00:05:32.080
some text

00:05:32.080 --> 00:05:34.479
write hashtag plus replace with and then

00:05:34.479 --> 00:05:36.240
write more text and you're good to go

00:05:36.240 --> 00:05:39.440
normal uh org markup um

00:05:39.440 --> 00:05:40.720
everyone speaks different languages

00:05:40.720 --> 00:05:42.479
maybe they want to use a

00:05:42.479 --> 00:05:45.919
uh one word or they're arguing about

00:05:45.919 --> 00:05:48.000
whether we talk about frames or windows

00:05:48.000 --> 00:05:49.759
um so maybe they want to have some

00:05:49.759 --> 00:05:50.560
translations

00:05:50.560 --> 00:05:52.479
right so there's different kinds of

00:05:52.479 --> 00:05:55.360
feedbacks uh let's let's take an example

00:05:55.360 --> 00:05:59.360
uh look at what they are okay

00:05:59.360 --> 00:06:02.560
uh so for example sasha might write

00:06:02.560 --> 00:06:06.160
uh this org mode right here and uh

00:06:06.160 --> 00:06:08.319
and then in her html exports you might

00:06:08.319 --> 00:06:09.759
see this

00:06:09.759 --> 00:06:12.080
and uh her feedback might look really

00:06:12.080 --> 00:06:13.840
nicely from anyone who says you know

00:06:13.840 --> 00:06:14.560
let's uh

00:06:14.560 --> 00:06:16.639
let's do some lisp instead of uh

00:06:16.639 --> 00:06:18.560
mathematics let's just do some list

00:06:18.560 --> 00:06:20.960
and and corwin says you know let's let's

00:06:20.960 --> 00:06:22.479
not be so silly

00:06:22.479 --> 00:06:25.120
maybe let's just say 9 a.m and move on

00:06:25.120 --> 00:06:28.080
okay

00:06:28.080 --> 00:06:31.360
um so amin likes to export to pdf

00:06:31.360 --> 00:06:33.039
and so he writes his top-level remarks

00:06:33.039 --> 00:06:34.720
using latex that's how

00:06:34.720 --> 00:06:37.600
so to get this uh square I mean please

00:06:37.600 --> 00:06:38.960
change whatever

00:06:38.960 --> 00:06:41.440
he might write like this hashtag you

00:06:41.440 --> 00:06:43.120
know plus latex

00:06:43.120 --> 00:06:46.960
hashtag plus latex right but then

00:06:46.960 --> 00:06:50.000
sasha only exports to p to html uh for

00:06:50.000 --> 00:06:50.880
example

00:06:50.880 --> 00:06:54.880
um and uh so she doesn't look at the pdf

00:06:54.880 --> 00:06:57.199
and she may not see his top-level

00:06:57.199 --> 00:06:58.560
feedback you know with those nice

00:06:58.560 --> 00:06:59.440
brackets and

00:06:59.440 --> 00:07:02.160
and bold right and so she might think

00:07:02.160 --> 00:07:03.120
everything's good

00:07:03.120 --> 00:07:06.160
right and that can be a bit disastrous

00:07:06.160 --> 00:07:09.039
um so maybe sasha will will then uh make

00:07:09.039 --> 00:07:09.440
some

00:07:09.440 --> 00:07:13.199
of her own feedback all right uh but

00:07:13.199 --> 00:07:16.160
and to produce it she might write html

00:07:16.160 --> 00:07:16.560
uh

00:07:16.560 --> 00:07:20.639
um html commands hashtag plus html to

00:07:20.639 --> 00:07:21.680
get that

00:07:21.680 --> 00:07:24.240
uh but then amin will make a pdf and

00:07:24.240 --> 00:07:25.680
this won't stick out

00:07:25.680 --> 00:07:27.759
and then so he might think everything's

00:07:27.759 --> 00:07:30.160
okay even even though it's not

00:07:30.160 --> 00:07:33.520
um then corwin actually decides hey

00:07:33.520 --> 00:07:36.240
uh let me read the exported result and

00:07:36.240 --> 00:07:36.800
these

00:07:36.800 --> 00:07:38.319
there's all those feedback from two

00:07:38.319 --> 00:07:39.919
people who haven't uh

00:07:39.919 --> 00:07:42.080
read anything because maybe they were in

00:07:42.080 --> 00:07:43.840
a russian and didn't

00:07:43.840 --> 00:07:46.400
see the top level feedback and so they

00:07:46.400 --> 00:07:48.160
agree hey let's have a uniform org

00:07:48.160 --> 00:07:50.000
interface that exports

00:07:50.000 --> 00:07:53.280
to both html and pdf make both of us

00:07:53.280 --> 00:07:54.080
happy

00:07:54.080 --> 00:07:57.280
okay so they decide to use org special

00:07:57.280 --> 00:07:58.160
blocks

00:07:58.160 --> 00:08:01.840
right um and to set this up they need to

00:08:01.840 --> 00:08:04.400
you know maybe read a little bit of lisp

00:08:04.400 --> 00:08:04.879
hooks

00:08:04.879 --> 00:08:08.879
advice macros to get all of this set up

00:08:08.879 --> 00:08:10.840
and then they'll use org as the main

00:08:10.840 --> 00:08:12.319
interface okay

00:08:12.319 --> 00:08:14.400
it's a lot of work but it's worth it

00:08:14.400 --> 00:08:16.479
right maybe

00:08:16.479 --> 00:08:19.360
um but then corwin corbin's a bit tears

00:08:19.360 --> 00:08:19.759
so

00:08:19.759 --> 00:08:22.960
uh corwin maybe doesn't want to write

00:08:22.960 --> 00:08:24.800
uh using blocks he thinks they're

00:08:24.800 --> 00:08:26.080
overkill and

00:08:26.080 --> 00:08:29.360
and sasha wants html and uh and

00:08:29.360 --> 00:08:31.840
I mean wants pdf and corwin wants org

00:08:31.840 --> 00:08:32.560
reveal

00:08:32.560 --> 00:08:34.240
so now they have to reformat all their

00:08:34.240 --> 00:08:36.320
code and then they need to use org link

00:08:36.320 --> 00:08:37.120
types to

00:08:37.120 --> 00:08:39.599
reduce the overkill all right so they

00:08:39.599 --> 00:08:41.519
can try to avoid duplication by

00:08:41.519 --> 00:08:44.000
factoring things out into self-contained

00:08:44.000 --> 00:08:46.800
uh defined functions or defunds

00:08:46.800 --> 00:08:50.320
um but now to set up or links

00:08:50.320 --> 00:08:53.440
uh we'll have uh to learn a new

00:08:53.440 --> 00:08:54.399
interface

00:08:54.399 --> 00:08:57.040
org setup link um learn a little bit

00:08:57.040 --> 00:08:58.000
about fonts

00:08:58.000 --> 00:09:02.160
follow links exports handles

00:09:02.160 --> 00:09:05.040
it's so much that's so much but but then

00:09:05.040 --> 00:09:06.800
you know the friends they learn a lot

00:09:06.800 --> 00:09:08.399
you know they learn about defund all

00:09:08.399 --> 00:09:11.120
right so these these words are red

00:09:11.120 --> 00:09:12.480
you get a little explanation I think

00:09:12.480 --> 00:09:14.320
it's a bit too small for anyone to read

00:09:14.320 --> 00:09:16.720
this is lisp documentation right for

00:09:16.720 --> 00:09:18.000
defund

00:09:18.000 --> 00:09:19.680
advice ad there's some list

00:09:19.680 --> 00:09:21.600
documentation right

00:09:21.600 --> 00:09:23.600
they learn about destructuring let's so

00:09:23.600 --> 00:09:25.279
this is from the dash library

00:09:25.279 --> 00:09:26.959
here's all that you know glorious

00:09:26.959 --> 00:09:28.800
glorious documentation with examples

00:09:28.800 --> 00:09:29.360
sorry

00:09:29.360 --> 00:09:31.680
I like that they might make an ad-hoc

00:09:31.680 --> 00:09:33.760
mechanism to simulate

00:09:33.760 --> 00:09:36.000
arguments for special blocks so

00:09:36.000 --> 00:09:37.040
something maybe called

00:09:37.040 --> 00:09:40.399
extract arguments and then of course to

00:09:40.399 --> 00:09:41.920
make new link types they have to learn

00:09:41.920 --> 00:09:42.480
about

00:09:42.480 --> 00:09:45.120
org link set parameters and then it's

00:09:45.120 --> 00:09:46.480
numerous uh

00:09:46.480 --> 00:09:49.920
bits and pieces all right so let's oh

00:09:49.920 --> 00:09:50.720
let's uh

00:09:50.720 --> 00:09:53.600
close all these ones down and and uh of

00:09:53.600 --> 00:09:55.040
course they also need to be uh

00:09:55.040 --> 00:09:56.080
comfortable with

00:09:56.080 --> 00:09:58.720
uh loops and maps and matching and

00:09:58.720 --> 00:09:59.920
string functions

00:09:59.920 --> 00:10:02.560
so it's it's a bit of a pain it's a bit

00:10:02.560 --> 00:10:03.360
of a pain

00:10:03.360 --> 00:10:05.839
um so it's probably not worth it so

00:10:05.839 --> 00:10:06.560
maybe I'll just

00:10:06.560 --> 00:10:09.360
rush things quickly or do an ad hoc you

00:10:09.360 --> 00:10:10.320
know

00:10:10.320 --> 00:10:13.680
we have things to do right

00:10:13.680 --> 00:10:15.920
so maybe maybe the squad wants to have a

00:10:15.920 --> 00:10:17.839
modular

00:10:17.839 --> 00:10:21.120
and unified interface so everyone's

00:10:21.120 --> 00:10:23.040
comfortable with defunct to define a

00:10:23.040 --> 00:10:25.279
function and they say you know what

00:10:25.279 --> 00:10:26.480
it would be nice if we could just you

00:10:26.480 --> 00:10:29.440
know define simultaneously

00:10:29.440 --> 00:10:32.959
both a block and the link type right

00:10:32.959 --> 00:10:34.880
and uh that way we have a single

00:10:34.880 --> 00:10:36.000
interface

00:10:36.000 --> 00:10:38.240
org mode for for these things and it

00:10:38.240 --> 00:10:39.040
would be nice was

00:10:39.040 --> 00:10:42.079
modular so if I defined a

00:10:42.079 --> 00:10:43.680
one kind of block and you defined

00:10:43.680 --> 00:10:45.519
another we could compose them

00:10:45.519 --> 00:10:47.600
right and then get a you know a nice

00:10:47.600 --> 00:10:49.360
bigger block like lego

00:10:49.360 --> 00:10:52.320
that would be nice building box okay and

00:10:52.320 --> 00:10:54.160
uh this is uh what we

00:10:54.160 --> 00:10:56.240
have come up with called death block and

00:10:56.240 --> 00:10:57.600
it also has a

00:10:57.600 --> 00:11:00.240
long documentation string containing

00:11:00.240 --> 00:11:01.760
examples and things

00:11:01.760 --> 00:11:04.800
so that way you can try to be useful

00:11:04.800 --> 00:11:08.320
okay um so let's let's look at a a

00:11:08.320 --> 00:11:10.880
solution to these friends uh trilemma

00:11:10.880 --> 00:11:12.800
all right so here's here's a way to

00:11:12.800 --> 00:11:14.320
define a block

00:11:14.320 --> 00:11:17.040
um it looks it's it doesn't look that

00:11:17.040 --> 00:11:19.200
difficult but this is how they can

00:11:19.200 --> 00:11:22.320
define a block for um

00:11:22.320 --> 00:11:25.920
for uh their top-level feedback right

00:11:25.920 --> 00:11:27.680
so let's let's look at the three main

00:11:27.680 --> 00:11:28.959
parts together

00:11:28.959 --> 00:11:31.920
it's not that uh difficult I hope just

00:11:31.920 --> 00:11:33.040
six lines

00:11:33.040 --> 00:11:34.720
and that's including a documentation

00:11:34.720 --> 00:11:36.160
string and you know

00:11:36.160 --> 00:11:39.440
uh new lines and things okay so in line

00:11:39.440 --> 00:11:41.279
one we just define the block just like

00:11:41.279 --> 00:11:42.000
you define

00:11:42.000 --> 00:11:44.880
a function we define a block the flag

00:11:44.880 --> 00:11:46.399
the block name is going to be called

00:11:46.399 --> 00:11:49.680
feedback it has an author who

00:11:49.680 --> 00:11:53.360
right the author has no default

00:11:53.360 --> 00:11:56.160
value it has a color and the color has a

00:11:56.160 --> 00:11:57.760
default value of red

00:11:57.760 --> 00:12:00.560
okay so just just as when you define

00:12:00.560 --> 00:12:01.680
functions they

00:12:01.680 --> 00:12:04.880
they uh you start by uh define

00:12:04.880 --> 00:12:08.639
or def block than the name some

00:12:08.639 --> 00:12:10.720
mandatory argument and some optional

00:12:10.720 --> 00:12:13.440
arguments okay

00:12:13.440 --> 00:12:15.760
then the next stage is well and

00:12:15.760 --> 00:12:18.480
definition a documentation you know

00:12:18.480 --> 00:12:20.880
uh the people who use this which are

00:12:20.880 --> 00:12:22.880
future you or future me you know

00:12:22.880 --> 00:12:25.519
uh might want to know what this is all

00:12:25.519 --> 00:12:27.839
right so let's get to document this

00:12:27.839 --> 00:12:30.560
uh and uh for for corwin who might want

00:12:30.560 --> 00:12:32.079
to use uh tooltips

00:12:32.079 --> 00:12:34.560
uh when corwin writes feedback whatever

00:12:34.560 --> 00:12:35.120
and

00:12:35.120 --> 00:12:37.120
Emacs they'll see a nice little tooltip

00:12:37.120 --> 00:12:38.639
and the tooltip will have

00:12:38.639 --> 00:12:41.279
this uh documentation string right so

00:12:41.279 --> 00:12:43.279
that'll be nice

00:12:43.279 --> 00:12:45.200
okay and then here's the third part the

00:12:45.200 --> 00:12:46.480
last three lines are

00:12:46.480 --> 00:12:49.440
not not so difficult if the back end is

00:12:49.440 --> 00:12:49.680
in

00:12:49.680 --> 00:12:52.800
is html the backend is html

00:12:52.800 --> 00:12:55.360
please use this template string

00:12:55.360 --> 00:12:57.440
otherwise use the other string

00:12:57.440 --> 00:13:00.639
okay and for each of these uh string

00:13:00.639 --> 00:13:01.279
markers

00:13:01.279 --> 00:13:03.600
please put in the color who wrote it and

00:13:03.600 --> 00:13:04.959
then the contents

00:13:04.959 --> 00:13:07.279
of the special block or the link type

00:13:07.279 --> 00:13:08.160
okay

00:13:08.160 --> 00:13:10.639
um so that's pretty neat not not so

00:13:10.639 --> 00:13:11.600
difficult

00:13:11.600 --> 00:13:14.639
so I thought that was kind of cool and

00:13:14.639 --> 00:13:15.519
then notice it's

00:13:15.519 --> 00:13:18.480
anaphoric it's it's a this this def

00:13:18.480 --> 00:13:19.519
block

00:13:19.519 --> 00:13:21.760
gives you two new names it gives you a

00:13:21.760 --> 00:13:22.560
name called

00:13:22.560 --> 00:13:25.120
uh contents and it gives you a name

00:13:25.120 --> 00:13:26.480
called back end

00:13:26.480 --> 00:13:29.040
right and so even if you're writing a

00:13:29.040 --> 00:13:31.040
def block and you intend it to be used

00:13:31.040 --> 00:13:32.560
only for links

00:13:32.560 --> 00:13:35.440
uh like the uh these colors for example

00:13:35.440 --> 00:13:37.600
uh these colors were defined using dev

00:13:37.600 --> 00:13:38.399
block

00:13:38.399 --> 00:13:41.279
uh and I used them as links right here

00:13:41.279 --> 00:13:43.360
and you don't need to worry

00:13:43.360 --> 00:13:44.880
where does the text come from in the

00:13:44.880 --> 00:13:48.160
link you know if I say red colon bob uh

00:13:48.160 --> 00:13:48.959
is it bob

00:13:48.959 --> 00:13:50.720
or if I put a description is it the

00:13:50.720 --> 00:13:52.000
description so

00:13:52.000 --> 00:13:54.000
it's whatever is available will will

00:13:54.000 --> 00:13:56.720
become uh the value of contents

00:13:56.720 --> 00:13:59.199
and if you're really you know interested

00:13:59.199 --> 00:14:00.320
and you want to do some

00:14:00.320 --> 00:14:03.839
intricate stuff uh def block also gives

00:14:03.839 --> 00:14:04.959
you something called

00:14:04.959 --> 00:14:08.160
raw dash contents if you really want to

00:14:08.160 --> 00:14:09.360
touch the raw

00:14:09.360 --> 00:14:11.920
uh contents with all of the org markups

00:14:11.920 --> 00:14:12.639
still there

00:14:12.639 --> 00:14:16.000
okay so let's uh let's see

00:14:16.000 --> 00:14:18.320
how uh everyone can uh communicate

00:14:18.320 --> 00:14:19.440
amongst themselves

00:14:19.440 --> 00:14:22.480
using this new interface okay so

00:14:22.480 --> 00:14:26.000
uh uh sasha speculates and she how does

00:14:26.000 --> 00:14:28.399
she speculate for her organ html

00:14:28.399 --> 00:14:31.440
she might just write hey look at that no

00:14:31.440 --> 00:14:34.800
no no html nice and and

00:14:34.800 --> 00:14:37.519
amin wants to have some green and so he

00:14:37.519 --> 00:14:39.600
just says hey here's some color green

00:14:39.600 --> 00:14:42.240
and and uh there you go it looks almost

00:14:42.240 --> 00:14:42.959
the same

00:14:42.959 --> 00:14:46.560
right uh notice that the main argument

00:14:46.560 --> 00:14:49.680
is right here def block took an author

00:14:49.680 --> 00:14:52.480
and here's the author again and now the

00:14:52.480 --> 00:14:53.920
optional argument

00:14:53.920 --> 00:14:57.360
uses the org babel source interface you

00:14:57.360 --> 00:14:58.000
just say

00:14:58.000 --> 00:15:00.639
colon and then a key and then the

00:15:00.639 --> 00:15:01.440
argument

00:15:01.440 --> 00:15:05.040
quite quite nice and and corwin doesn't

00:15:05.040 --> 00:15:05.519
want to

00:15:05.519 --> 00:15:07.920
use blocks it's a bit of an overkill and

00:15:07.920 --> 00:15:09.760
can just write a

00:15:09.760 --> 00:15:12.959
a little um right

00:15:12.959 --> 00:15:16.000
so the main argument is now the uh uh

00:15:16.000 --> 00:15:17.440
the label of the link

00:15:17.440 --> 00:15:19.360
all right and then the description of

00:15:19.360 --> 00:15:21.600
the link is the contents

00:15:21.600 --> 00:15:24.959
of uh of the feedback so that was quite

00:15:24.959 --> 00:15:25.680
nice

00:15:25.680 --> 00:15:28.079
so it looks like uh everyone uses the

00:15:28.079 --> 00:15:29.360
same interface on the left

00:15:29.360 --> 00:15:32.800
and can have varying uh outputs

00:15:32.800 --> 00:15:34.480
and it looks I think it looks quite nice

00:15:34.480 --> 00:15:36.639
and I hope you do too

00:15:36.639 --> 00:15:40.000
um and there's a few more maybe

00:15:40.000 --> 00:15:42.160
as you saw in some previous ones we had

00:15:42.160 --> 00:15:43.920
text side beside side

00:15:43.920 --> 00:15:46.800
right now um or we folded some regions

00:15:46.800 --> 00:15:47.440
away

00:15:47.440 --> 00:15:49.360
that was quite nice we put some things

00:15:49.360 --> 00:15:50.959
in pretty boxes

00:15:50.959 --> 00:15:54.000
um uh we had some spoilers at the very

00:15:54.000 --> 00:15:57.120
beginning that we we uh hit some text uh

00:15:57.120 --> 00:15:58.160
we demoed uh

00:15:58.160 --> 00:15:59.600
some texts right you know here's some

00:15:59.600 --> 00:16:01.680
org and here's what it looks like

00:16:01.680 --> 00:16:04.480
um and and most importantly uh they they

00:16:04.480 --> 00:16:05.199
compose

00:16:05.199 --> 00:16:08.320
right there's uh uh there's a

00:16:08.320 --> 00:16:12.639
a macro called uh uh thread block

00:16:12.639 --> 00:16:14.720
uh thread block a thread block call and

00:16:14.720 --> 00:16:16.160
it lets you thread the

00:16:16.160 --> 00:16:18.000
the contents through a number of blocks

00:16:18.000 --> 00:16:20.639
treating them as if they were functions

00:16:20.639 --> 00:16:22.480
and so really you can think of a block

00:16:22.480 --> 00:16:23.680
as a as a

00:16:23.680 --> 00:16:26.560
as a string valued function so that's

00:16:26.560 --> 00:16:27.360
pretty neat

00:16:27.360 --> 00:16:30.959
I I think and uh thank you for listening

00:16:30.959 --> 00:16:31.759
and uh

00:16:31.759 --> 00:16:34.320
I I hope you've uh enjoyed this little

00:16:34.320 --> 00:16:34.880
uh

00:16:34.880 --> 00:16:37.600
happy fun time with uh with the Emacs

00:16:37.600 --> 00:16:38.160
and friends

00:16:38.160 --> 00:16:40.720
and uh I'll I'm I'll happy happily

00:16:40.720 --> 00:16:41.759
answer questions

00:16:41.759 --> 00:16:43.730
uh right now um

00:16:43.730 --> 00:16:45.360
[Music]

00:16:45.360 --> 00:16:48.160
so uh someone says why did you put

00:16:48.160 --> 00:16:50.480
optional arguments in a separate list

00:16:50.480 --> 00:16:53.600
rather than using cl style argument

00:16:53.600 --> 00:16:54.560
lists

00:16:54.560 --> 00:16:58.399
um so that's a very good question

00:16:58.399 --> 00:17:01.680
and I will answer that by

00:17:01.680 --> 00:17:04.400
showing you a more involved definition

00:17:04.400 --> 00:17:04.880
of

00:17:04.880 --> 00:17:08.959
feedback so let's look at a

00:17:08.959 --> 00:17:13.039
a more involved one

00:17:13.039 --> 00:17:16.079
right right here so for example

00:17:16.079 --> 00:17:19.280
this one is called rural mark all right

00:17:19.280 --> 00:17:21.760
and uh please let me know if my text is

00:17:21.760 --> 00:17:23.439
not sufficiently big

00:17:23.439 --> 00:17:26.799
so here is here is why uh we have

00:17:26.799 --> 00:17:29.520
two arguments that takes two arguments

00:17:29.520 --> 00:17:30.720
uh instead of one

00:17:30.720 --> 00:17:33.360
for for its argument list right so you

00:17:33.360 --> 00:17:34.799
you have def block

00:17:34.799 --> 00:17:37.679
then you have the name right then you

00:17:37.679 --> 00:17:38.400
have

00:17:38.400 --> 00:17:40.960
the first uh argument list and the

00:17:40.960 --> 00:17:42.880
second argument list

00:17:42.880 --> 00:17:46.080
the first argument list uh takes the

00:17:46.080 --> 00:17:49.280
takes the text right after the begin

00:17:49.280 --> 00:17:51.760
right the text right after the begin is

00:17:51.760 --> 00:17:52.320
the main

00:17:52.320 --> 00:17:55.760
argument okay and then the remaining key

00:17:55.760 --> 00:17:57.039
value pairs

00:17:57.039 --> 00:18:00.320
are in the second argument list okay

00:18:00.320 --> 00:18:03.280
now the reason we have two is because uh

00:18:03.280 --> 00:18:04.640
in order to

00:18:04.640 --> 00:18:06.799
streamline the interface to account for

00:18:06.799 --> 00:18:08.880
both uh special blocks

00:18:08.880 --> 00:18:12.320
and or link types uh what we do is we

00:18:12.320 --> 00:18:13.360
say hey

00:18:13.360 --> 00:18:16.160
uh in the first argument list uh you can

00:18:16.160 --> 00:18:18.000
give a name to the first argument

00:18:18.000 --> 00:18:21.039
give it a default value and anything

00:18:21.039 --> 00:18:24.240
else you provide will become uh

00:18:24.240 --> 00:18:27.760
uh part of the I'll co link

00:18:27.760 --> 00:18:30.000
information so for example this link we

00:18:30.000 --> 00:18:32.000
decided to make its face

00:18:32.000 --> 00:18:34.799
angry red um you might want to give

00:18:34.799 --> 00:18:35.840
other features to

00:18:35.840 --> 00:18:37.919
links so we're trying to streamline the

00:18:37.919 --> 00:18:39.679
interface for both

00:18:39.679 --> 00:18:42.320
special blocks and org link types and we

00:18:42.320 --> 00:18:42.880
thought

00:18:42.880 --> 00:18:46.240
this way was quite nice um so

00:18:46.240 --> 00:18:49.840
that was the main reason uh someone asks

00:18:49.840 --> 00:18:52.480
uh so if if you uh if that's uh if you

00:18:52.480 --> 00:18:55.039
need if you have follow-up please ask

00:18:55.039 --> 00:18:57.600
someone asks do you intend to try to

00:18:57.600 --> 00:19:00.559
upstream this amazing work into org

00:19:00.559 --> 00:19:03.600
well I'm glad you like it I I don't know

00:19:03.600 --> 00:19:04.559
how to upstream

00:19:04.559 --> 00:19:06.880
but but I I will look into it and any

00:19:06.880 --> 00:19:08.799
advice or guidance would be

00:19:08.799 --> 00:19:11.840
much appreciated um you know

00:19:11.840 --> 00:19:14.640
lisp is awesome and just as defunded as

00:19:14.640 --> 00:19:17.120
a macro deathblock is a macro and then

00:19:17.120 --> 00:19:20.240
source blocks are awesome and then now

00:19:20.240 --> 00:19:21.919
maybe we can have arguments and special

00:19:21.919 --> 00:19:24.080
blocks and motivate and encourage more

00:19:24.080 --> 00:19:25.280
people to uh

00:19:25.280 --> 00:19:28.799
to uh learn lisp right

00:19:28.799 --> 00:19:32.559
so another person asks

00:19:32.559 --> 00:19:35.280
um what is used to produce colorful

00:19:35.280 --> 00:19:38.559
boxes around the cursor

00:19:38.559 --> 00:19:40.400
I I'm not quite sure if you're asking

00:19:40.400 --> 00:19:41.840
are you talking about my cursor right

00:19:41.840 --> 00:19:42.559
here

00:19:42.559 --> 00:19:48.400
or are you talking about in the slide um

00:19:48.400 --> 00:19:50.559
so this this this cursor is some

00:19:50.559 --> 00:19:52.400
application called

00:19:52.400 --> 00:19:55.440
a stream brush that I had to purchase uh

00:19:55.440 --> 00:19:57.679
unfortunately I could not find a a

00:19:57.679 --> 00:19:59.039
suitable free one

00:19:59.039 --> 00:20:02.159
um and the blocks I can demonstrate some

00:20:02.159 --> 00:20:03.840
Emacs list but I can open up my Emacs if

00:20:03.840 --> 00:20:05.679
people like and we can try some things

00:20:05.679 --> 00:20:06.320
out

00:20:06.320 --> 00:20:09.440
happy to do that uh

00:20:09.440 --> 00:20:12.480
you're welcome uh someone asks

00:20:12.480 --> 00:20:14.880
a side question about org reveal how do

00:20:14.880 --> 00:20:15.520
you get

00:20:15.520 --> 00:20:17.440
bespoke or multiple column layouts

00:20:17.440 --> 00:20:19.120
without using html

00:20:19.120 --> 00:20:22.559
ah excellent question that's what we do

00:20:22.559 --> 00:20:24.640
that's that's what this uh project is

00:20:24.640 --> 00:20:26.000
about so it's not

00:20:26.000 --> 00:20:28.960
org reveal it's it's our fancy parallel

00:20:28.960 --> 00:20:29.440
uh

00:20:29.440 --> 00:20:32.240
uh block so we have this thing you say

00:20:32.240 --> 00:20:33.440
begin parallel

00:20:33.440 --> 00:20:35.679
you say how many columns you would like

00:20:35.679 --> 00:20:37.120
uh do you want a bar

00:20:37.120 --> 00:20:39.679
or not and then you write some text and

00:20:39.679 --> 00:20:40.960
then you uh

00:20:40.960 --> 00:20:42.480
you get some text and according with the

00:20:42.480 --> 00:20:44.400
bar or not right so that's

00:20:44.400 --> 00:20:47.520
that's how we achieve that in our slides

00:20:47.520 --> 00:20:50.080
so I'm not uh I'm not quite sure where

00:20:50.080 --> 00:20:52.880
this was

00:20:52.880 --> 00:20:59.520
somewhere here I think

00:20:59.520 --> 00:21:06.240
let me try to find this for you

00:21:06.240 --> 00:21:08.320
I can't seem to find where the parallel

00:21:08.320 --> 00:21:09.440
blocks were

00:21:09.440 --> 00:21:12.159
apologies let's move on to the next

00:21:12.159 --> 00:21:15.039
question I suppose

00:21:15.039 --> 00:21:17.760
uh I'm pretty sure they're here ah there

00:21:17.760 --> 00:21:18.400
they are

00:21:18.400 --> 00:21:21.360
yes so these these uh were just

00:21:21.360 --> 00:21:22.640
instances of using

00:21:22.640 --> 00:21:25.440
uh the parallel block and it makes

00:21:25.440 --> 00:21:26.480
things parallel

00:21:26.480 --> 00:21:29.600
so that's quite nice um another person

00:21:29.600 --> 00:21:33.360
asks uh yes

00:21:33.360 --> 00:21:36.720
excellent um how does this relate to

00:21:36.720 --> 00:21:37.840
banda pandoc

00:21:37.840 --> 00:21:39.360
which is used for converting between

00:21:39.360 --> 00:21:40.960
markup formats

00:21:40.960 --> 00:21:43.919
so all we're doing is we're we're saying

00:21:43.919 --> 00:21:44.400
hey

00:21:44.400 --> 00:21:46.799
please write org because org is just

00:21:46.799 --> 00:21:47.679
fantastic

00:21:47.679 --> 00:21:50.400
and we love it and it's the dream and if

00:21:50.400 --> 00:21:51.760
you would like to view things

00:21:51.760 --> 00:21:55.039
in html or in org reveal or

00:21:55.039 --> 00:21:58.559
in pdf that's up to the user so

00:21:58.559 --> 00:22:02.320
here is a um oh

00:22:02.320 --> 00:22:05.039
made it too small now so here is a an

00:22:05.039 --> 00:22:06.080
example

00:22:06.080 --> 00:22:08.880
so here's an uh how here's how parallel

00:22:08.880 --> 00:22:10.240
is implemented

00:22:10.240 --> 00:22:13.120
uh just as a quick example uh not too

00:22:13.120 --> 00:22:14.320
long

00:22:14.320 --> 00:22:16.880
uh about half of the implementation is

00:22:16.880 --> 00:22:18.400
documentation so

00:22:18.400 --> 00:22:20.720
uh hopefully that speaks for for how

00:22:20.720 --> 00:22:22.720
useful this feature is

00:22:22.720 --> 00:22:25.280
uh so we decide if there's a rule or not

00:22:25.280 --> 00:22:28.080
um we look for the column break

00:22:28.080 --> 00:22:29.760
and really here we're looking at the

00:22:29.760 --> 00:22:31.840
back end if the back end is latex

00:22:31.840 --> 00:22:34.960
uh please use this uh incantation with

00:22:34.960 --> 00:22:37.679
multi columns mini pages what have you

00:22:37.679 --> 00:22:38.559
and if the

00:22:38.559 --> 00:22:41.039
back end is something else uh please uh

00:22:41.039 --> 00:22:41.600
do this

00:22:41.600 --> 00:22:44.960
uh div and style and uh other uh

00:22:44.960 --> 00:22:46.640
gibberish that we don't really wanna

00:22:46.640 --> 00:22:48.080
look at uh so

00:22:48.080 --> 00:22:51.760
uh when you pandoc works from org

00:22:51.760 --> 00:22:55.280
so it might not work directly since our

00:22:55.280 --> 00:22:58.080
interface the way we set it up is when

00:22:58.080 --> 00:22:59.679
you try to export

00:22:59.679 --> 00:23:01.919
uh we hook in and we do a bunch of

00:23:01.919 --> 00:23:03.039
pre-processing

00:23:03.039 --> 00:23:05.919
so this this uh def block is a is a

00:23:05.919 --> 00:23:07.440
string valued function

00:23:07.440 --> 00:23:10.880
and so whenever we see these uh begin

00:23:10.880 --> 00:23:13.919
parallel uh when you do an export

00:23:13.919 --> 00:23:16.480
I tell Emacs hold up look for those

00:23:16.480 --> 00:23:16.960
begin

00:23:16.960 --> 00:23:19.360
parallels please oh you found them grab

00:23:19.360 --> 00:23:20.320
that text

00:23:20.320 --> 00:23:22.400
you grabbed it great now please apply

00:23:22.400 --> 00:23:24.080
this person's uh function

00:23:24.080 --> 00:23:27.120
onto that text and splice in the result

00:23:27.120 --> 00:23:29.760
okay so so when you export uh we're

00:23:29.760 --> 00:23:30.400
performing

00:23:30.400 --> 00:23:33.600
arbitrary computations on your uh uh on

00:23:33.600 --> 00:23:35.120
your text

00:23:35.120 --> 00:23:38.799
so uh um some people might not find that

00:23:38.799 --> 00:23:40.159
comforting to have

00:23:40.159 --> 00:23:43.039
arbitrary uh computations happening so

00:23:43.039 --> 00:23:45.039
in this article there's a few where

00:23:45.039 --> 00:23:47.520
uh we change your text upon export we

00:23:47.520 --> 00:23:48.320
translate it

00:23:48.320 --> 00:23:51.760
we do other things to it um

00:23:51.760 --> 00:23:55.360
so someone says uh if you export to

00:23:55.360 --> 00:23:57.360
latex to pdf does that work well with

00:23:57.360 --> 00:23:58.640
beamer as well

00:23:58.640 --> 00:24:00.320
to create slides with columns for

00:24:00.320 --> 00:24:02.080
example for uh

00:24:02.080 --> 00:24:05.200
um so uh actually uh

00:24:05.200 --> 00:24:08.000
so uh I I made a bunch of these changes

00:24:08.000 --> 00:24:09.200
earlier this morning

00:24:09.200 --> 00:24:12.320
and it just says latex right here um

00:24:12.320 --> 00:24:14.480
so if you want to go to beamer I think

00:24:14.480 --> 00:24:15.360
the back end for me

00:24:15.360 --> 00:24:18.240
beamer is called well beamer so instead

00:24:18.240 --> 00:24:18.960
of a

00:24:18.960 --> 00:24:21.200
a p case what we would do is we would

00:24:21.200 --> 00:24:22.000
say oh

00:24:22.000 --> 00:24:25.360
if it's a latex or it's a beamer

00:24:25.360 --> 00:24:29.279
then uh use this uh otherwise

00:24:29.279 --> 00:24:31.120
it's not a latex it will simply default

00:24:31.120 --> 00:24:33.039
to this one which could be

00:24:33.039 --> 00:24:36.400
dangerous for your needs um I think it's

00:24:36.400 --> 00:24:39.679
a bad practice to put a underscore but I

00:24:39.679 --> 00:24:41.279
did it really quickly because I just

00:24:41.279 --> 00:24:43.679
wanted to show you that it works fine in

00:24:43.679 --> 00:24:46.559
org reveal contributions are more than

00:24:46.559 --> 00:24:47.440
welcome

00:24:47.440 --> 00:24:51.039
I I uh happily uh would love any

00:24:51.039 --> 00:24:52.240
assistance

00:24:52.240 --> 00:24:56.080
um and and I have a uh we have a

00:24:56.080 --> 00:24:58.640
list a reference cheat sheet here to to

00:24:58.640 --> 00:25:00.159
learn a little bit about lisp if you're

00:25:00.159 --> 00:25:02.000
not comfortable or to

00:25:02.000 --> 00:25:04.640
ask some questions lots of helpful

00:25:04.640 --> 00:25:06.400
people

00:25:06.400 --> 00:25:09.440
so there's another question that says uh

00:25:09.440 --> 00:25:11.679
does typing in a block mess up with a

00:25:11.679 --> 00:25:13.120
syntax highlighting

00:25:13.120 --> 00:25:15.679
usually you use a single color inside an

00:25:15.679 --> 00:25:17.279
example block for example

00:25:17.279 --> 00:25:21.279
ah you found my crutch you found

00:25:21.279 --> 00:25:25.279
my crutch um so I so there's

00:25:25.279 --> 00:25:27.440
emax's is all encompassing and I'm not

00:25:27.440 --> 00:25:29.760
quite sure how fonts work or are

00:25:29.760 --> 00:25:32.559
you know I I learned enough to get by I

00:25:32.559 --> 00:25:33.840
learned enough to get by

00:25:33.840 --> 00:25:37.440
so let me um but here's

00:25:37.440 --> 00:25:39.760
here's how links work they're they're a

00:25:39.760 --> 00:25:40.799
bit complicated

00:25:40.799 --> 00:25:42.960
this this is a bit scary I don't

00:25:42.960 --> 00:25:43.919
recommend anyone

00:25:43.919 --> 00:25:47.039
uh read it um

00:25:47.039 --> 00:25:49.840
but uh actually let me open up an email

00:25:49.840 --> 00:25:50.559
and you can

00:25:50.559 --> 00:25:53.600
you can see what I see uh so here's an

00:25:53.600 --> 00:25:54.799
Emacs

00:25:54.799 --> 00:25:56.799
all right let's make that a bit bigger

00:25:56.799 --> 00:25:58.400
uh let's change this

00:25:58.400 --> 00:26:01.200
slightly nope that's worse there you go

00:26:01.200 --> 00:26:01.919
so

00:26:01.919 --> 00:26:05.760
here's here's some words um so here's

00:26:05.760 --> 00:26:09.360
red hello um

00:26:09.360 --> 00:26:12.000
but you're worried about uh preserving

00:26:12.000 --> 00:26:12.400
uh

00:26:12.400 --> 00:26:15.679
uh uh um quantification

00:26:15.679 --> 00:26:18.480
so let's make an emax list block all

00:26:18.480 --> 00:26:18.880
right

00:26:18.880 --> 00:26:22.840
and let's say plus one two ah

00:26:22.840 --> 00:26:28.000
where's the fun hello

00:26:28.000 --> 00:26:32.080
um bye okay where's the coloring

00:26:32.080 --> 00:26:34.880
if we if we zoom in on this on this

00:26:34.880 --> 00:26:36.000
begin source block

00:26:36.000 --> 00:26:39.200
if we zoom in you can see down here

00:26:39.200 --> 00:26:42.159
uh we have our our coloring all right

00:26:42.159 --> 00:26:43.279
when we zoom in

00:26:43.279 --> 00:26:46.960
if we if we zoom out ah no coloring

00:26:46.960 --> 00:26:50.080
zoom in coloring it's about ah no

00:26:50.080 --> 00:26:50.880
coloring

00:26:50.880 --> 00:26:53.840
let's take off these bad boys and oh

00:26:53.840 --> 00:26:55.679
look my coloring's back

00:26:55.679 --> 00:26:59.360
so um in a previous

00:26:59.360 --> 00:27:02.320
uh iteration of the system I was able to

00:27:02.320 --> 00:27:03.760
maintain coloring

00:27:03.760 --> 00:27:06.400
uh in this new iteration I am not I

00:27:06.400 --> 00:27:08.559
don't know how to do it I haven't uh

00:27:08.559 --> 00:27:11.039
had the time to to implement it I spent

00:27:11.039 --> 00:27:13.279
a lot of time writing this uh

00:27:13.279 --> 00:27:17.279
48 page uh documentation uh with uh

00:27:17.279 --> 00:27:19.679
with some fun examples to to to try to

00:27:19.679 --> 00:27:20.320
help

00:27:20.320 --> 00:27:21.760
people learn so but but I would

00:27:21.760 --> 00:27:23.760
appreciate any help or guidance on

00:27:23.760 --> 00:27:26.240
how to uh maintain the quantification I

00:27:26.240 --> 00:27:28.000
I really would like to keep those colors

00:27:28.000 --> 00:27:29.200
in

00:27:29.200 --> 00:27:31.840
um musa we have time for maybe one more

00:27:31.840 --> 00:27:32.640
question

00:27:32.640 --> 00:27:34.960
um one or two more questions and then we

00:27:34.960 --> 00:27:37.039
have to move on to the next talk

00:27:37.039 --> 00:27:39.120
um but yeah you're more than welcome to

00:27:39.120 --> 00:27:40.799
take continue taking the questions via

00:27:40.799 --> 00:27:42.559
irc or the pad

00:27:42.559 --> 00:27:45.760
okay thank you thank you

00:27:45.760 --> 00:27:48.480
let's uh the final question we'll take

00:27:48.480 --> 00:27:48.880
is

00:27:48.880 --> 00:27:52.320
um should packages implement

00:27:52.320 --> 00:27:54.399
interface to one specific format or

00:27:54.399 --> 00:27:55.840
attempt to be conclusive to all the

00:27:55.840 --> 00:27:57.279
potential output targets

00:27:57.279 --> 00:27:58.880
I think you should just make them as you

00:27:58.880 --> 00:28:01.120
go and you know add them as you need

00:28:01.120 --> 00:28:02.559
them we'll make uh

00:28:02.559 --> 00:28:05.600
help requests or things and uh

00:28:05.600 --> 00:28:07.840
we can we can share recipes in this uh

00:28:07.840 --> 00:28:09.279
document and then

00:28:09.279 --> 00:28:12.799
try to add other uh techniques and then

00:28:12.799 --> 00:28:16.000
and we can uh use these blocks as a

00:28:16.000 --> 00:28:19.200
common uh interface for

00:28:19.200 --> 00:28:22.240
for exporting to pdf and other things

00:28:22.240 --> 00:28:26.000
and since someone asked here is a um

00:28:26.000 --> 00:28:28.399
here is uh what a pdf looks like this is

00:28:28.399 --> 00:28:30.159
the same pdf and

00:28:30.159 --> 00:28:33.840
uh rendered uh just I made no effort to

00:28:33.840 --> 00:28:34.960
make it look good

00:28:34.960 --> 00:28:37.840
but it surprisingly does look good so so

00:28:37.840 --> 00:28:38.559
uh that was

00:28:38.559 --> 00:28:41.600
uh that was nice um that was a

00:28:41.600 --> 00:28:44.320
terrible magenta but that is life uh

00:28:44.320 --> 00:28:44.880
anyhow

00:28:44.880 --> 00:28:47.279
I hope you all enjoyed this talk I hope

00:28:47.279 --> 00:28:48.960
you will find um

00:28:48.960 --> 00:28:51.679
death block uh useful to you it is

00:28:51.679 --> 00:28:52.799
available on melbourne

00:28:52.799 --> 00:28:54.960
uh in a rush to make it available for

00:28:54.960 --> 00:28:57.679
EmacsConf 2020 some melba

00:28:57.679 --> 00:29:00.159
guidelines may not have been in here too

00:29:00.159 --> 00:29:00.960
please do not

00:29:00.960 --> 00:29:03.200
hit me um and I hope everyone enjoys the

00:29:03.200 --> 00:29:04.720
rest of the EmacsConf

00:29:04.720 --> 00:29:08.559
2020 thank you
