Adám

@KamilaSzewczyk how many different lengths can aStart have?

Kamila Szewczyk

if i wanted to turn this outer tradfn into dfn

@Adám 3

nothing, one element, two elements

[continuing], i'd need to pass value being omega to the other value below, and the only way would be redefining omega, but i think i could pass it as alpha to the inner dfn, so how would I do that?

Adám

@KamilaSzewczyk The inner :If can be iterator←(1⌈≢aStart)⊃'⍵+1'(2⊃aStart)

ngn

@KamilaSzewczyk why not a dop instead of dfn?

Kamila Szewczyk

hmm?

ngn

13:04

{⍵×2}Stream 2 instead of Stream '⍵×2' 2

Kamila Szewczyk

that'd be nice

i'll need to then restructure the entire code

but my process of thought is much better when i have a working prototype to work with

ngn

then limit can be another operator that takes a limiting function and a stream, and returns another stream

Kamila Szewczyk

yeah

ngn

the "stream object" could be a namespace, as adam suggested

Kamila Szewczyk

are namespaces instantiable in APL?

ngn

13:08

yes, ns←⎕ns⍬ and you can assign to it with ns.prop←123 or ns.f←{..}

Adám

You just create a new one with ⎕NS

Kamila Szewczyk

hmmm

wait

that makes a lot of sense

dzaima

@KamilaSzewczyk APLs namespaces are like JS objects

Kamila Szewczyk

i didn't know that, but now I do

ngn

@KamilaSzewczyk but beware, they are mutable objects

which is probably ok for your purposes

Kamila Szewczyk

13:09

how does one copy a namespace?

Adám

⎕NS

Kamila Szewczyk

hmm, i see

thanks

@ngn oh wait

so i'd be able to assign this dfn on the left into the namespace, and this way invoke it elsewhere

Adám

Pro-tip: APLcart can help with many namespace-related tasks.

@KamilaSzewczyk Yes.

Kamila Szewczyk

yeah this is much better design

ngn

@KamilaSzewczyk yes, i mean something like Stream←{s←⎕ns⍬⋄s.next←⍺⍺⋄s.initial←⍵}

Kamila Szewczyk

13:11

i didn't know i can do that

I see now

rak1507

no results :(

xpqz

@rak1507 Not your favourite Dyalog feature?

Kamila Szewczyk

"how to go back in time and inspire john scholes to make dfns before tradfns are a thing" :)

Adám

@rak1507 It isn't as if you must use them.

rak1507

@xpqz I'm half joking

Adám

13:13

@KamilaSzewczyk I wish I could find the video where John Scholes uses a negative argument to ⎕DL

We should totally amend the error message for that:

      ⎕DL ¯3
DOMAIN ERROR: Cannot reverse time
      ⎕DL ¯3
      ∧

rak1507

what if you did ⎕DL ¯something and it inserted the result back the way in the session log

Adám

@rak1507 That's exactly what happened in the video.

rak1507

yeah I know

Adám

Did you see the video?

rak1507

I think so, but maybe I just heard about it

Adám

13:23

If someone wants to go search for it…

dzaima

dzaima/APL and dzaima/BQN interop because why not

Adám

@dzaima That was basically my point about ⎕EL from yesterday.

ngn

Stream←{s←⎕ns⍬⋄s.f←⍺⍺⋄s.x←⍵⋄s}
map   ←{s←⎕ns⍵⋄s.f←⍺⍺∘s.f⋄s}

s←{⍵×2}Stream 2
s←{⍵+1}map s
s←{⍵>100}limit s
{⎕←⍵}each s

@KamilaSzewczyk ^my attempt to write it with dfns

Kamila Szewczyk

damn that's really nice

and very short

but i think you forgot filter

xpqz

@ngn nice

ngn

13:38

thanks

dzaima

@Adám except that here it's two separate interpreters, not one with different modes

Adám

@dzaima Right, so even simpler to do in my case.

ngn

@KamilaSzewczyk there was no filter in the screenshot. left as an exercise to the reader :)

Kamila Szewczyk

lol

okay, that's very elegant though

much better than whatever i had before

there's no collect too

i think skip n, filter, and collect are hard(er) here because this much as you show (or a bit more) i've had before

Adám

CMP: What should the error message be when attempting to travel back in time using ⎕DL on a negative number?

2

ngn

13:41

@Adám the closest error message from that many seconds ago in the session log :)

or: please insert time travel floppy disc in drive 1. A)bort R)etry F)ail

Stream←{s←⎕ns⍬⋄s.f←⍺⍺⋄s.x←⍵⋄s}
map   ←{s←⎕ns⍵⋄s.f←⍺⍺∘s.f⋄s}

end←⎕ns⍬

{⎕←⍵}each {⍵>100}limit {⍵>10}filter {⍵+1}map {⍵×2}Stream 2

@KamilaSzewczyk ^improved version

(filter doesn't apply to the initial value)

Kamila Szewczyk

i love the fact that it's reversed

but it can most probably be modded easily to the good order

i'll try it later

ngn

it's just the way apl syntax works

rak1507

14:14

@Adám time travel was officially deprecated in 2050

Adám

@rak1507 That's not bad at all: How about "time travel will be deprecated"?

rak1507

Maybe but that seems to imply that it isn't deprecated currently

Adám

True.

Marshall

@Adám Error: messages to the past were removed in version {increment current version number}

Probably increment three times, to make sure it's not a version in development.

"Programming in the past was disabled during version {} development"

rak1507

14:30

what if dyalog includes some extra secret performance algorithms that only activate if you do ⎕DL⍣¯1

RGS

Later today I will be meeting with some college students about a workshop I'll be leading on solving rosalind-type bioinformatics problems. I'll try to sell them the idea of doing the workshop in APL :D

rak1507

@RGS I started doing some of the problems yesterday (in APL), they're pretty good

RGS

Yeah they are

Adám

@Marshall Why "messages"? And not simply "Support for negative values was removed in version 42"?

Kamila Szewczyk

@rak1507 inb4 have it enabling fast yet imprecise math

rak1507

14:42

lol

dzaima

@Adám libtimetravel.so not found

Adám

@dzaima libtimetravel.so will not be found

How about simply Not implemented yet?

dzaima

@Adám beautiful

DOMAIN ERROR: negative delay not implemented, yet

Adám

DOMAIN ERROR: Not implemented, yet

dzaima

@Adám might be a bit confusing when e.g. accidentally swapping - args in a complicated function if it doesn't specify what went wrong

Adám

14:49

Good point.

Razetime

@Adám DOMAIN ERROR: Please do not disturb the temporal realm

xpqz

@Razetime But you can't, so what's the point of asking for it.

Razetime

@xpqz Still need to watch it ⍨

dzaima

rak1507

I like that one

@Adám :D yeah

rak1507

what if you did ⎕DL ¯big number and it restyled the IDE to look like a mainframe terminal

Adám

Razetime

@Adám or don't error and delay |⍵ seconds

Adám

@Razetime How so? That's just wrong.

rak1507

CMC: produce a vector 1 0 1 0 ... of length ⍵

Adám

⍴∘1 0

rak1507

oops, length ≢⍵

Adám

What is the nature of ⍵?

Simple vector? Any array?

rak1507

15:08

a vector, so f 1 8 3 4 2 3 should be 1 0 1 0 1 0

Adám

General vector solution: ≠\1⍨¨

Simple vector solution: ≠\=⍨

rak1507

ah yeah ≠\, I had >\

Razetime

I had 2∘|∘⍳∘≢

too long I guess

Adám

@Razetime Why not 2|⍳⍤≢?

dzaima

@Razetime 2|⍳∘≢

Razetime

15:10

Well I didn't test it

rak1507

that's wrong with ⎕IO←0 anyway ;)

Razetime

meh

Adám

Fun solution: ≠\⍬∘⍳

rak1507

IO dependent :(

Adám

Iterative solution: ¯1(⊢,∘~↑)⍣⎕⊢⍬

ngn

15:14

@dzaima that's a good one :) also: "downloading libtimetravel.so ..", progress bar going backwards, and suddenly: "download failed, please try again 5 minutes ago"

Adám

rak1507

@ngn I like that one

Adám

Or simply DOMAIN ERROR: Not yet

DOMAIN ERROR: Wait for it...

rak1507

15:19

Is there a way to remove the parens in ⊢⌺(≢⍵) ?

Razetime

show the history getting deleted line by line to spook the user

Adám

@rak1507 No, you can never remove the parens around a right operand, just like you cannot around a left argument.

rak1507

:(

ngn

@rak1507 yes, <backspace><left><left><left><delete> :)

@Razetime :D

Adám

⋄ {⎕FMT⍵,⎕UCS(4/8),(4/8),,∘⌽⍨0 32} '⊢⌺(≢⍵)'

Dyalog APL

15:24

@Adám Illegal code

Marshall

@Adám Yeah, the "programming in the past" version is better. To me, "time travel" abstracts it too much to really be funny. And I like suggesting that it's happening in the near future (how exciting!), so bumping the version number is a nice trick.

Adám

Morten suggested changing it to a NONCE ERROR, to indicate that it might be implemented in the future.

Razetime

nice

Marshall

NONCE ERROR, no message, is nice and subtle, but makes it possible for someone to get tripped up on the unexpected error code.

Adám

I know, which is why I think a DMX message is a better Easter egg

Apparently, at IPSA the APLers got hyped whenever someone hit a NONCE ERROR, as that meant a new feature was imminent…

rak1507

15:30

What if you do ⎕DL imaginary number and the error is 'maximum number of dimensions exceeded' or something

ngn

cmpx '⎕dl 1' '⎕dl ¯1' would be interesting

Marshall

@Adám In my experience NONCE ERRORs are some of the least likely to ever be fixed.

rak1507

what generally causes a nonce error?

ngn

⊃0⍴#

Adám

@rak1507 It basically means "not implemented yet".

rak1507

15:32

ah

cmc: shortest code to cause a nonce error? (probably ngns)

Adám

from the idiom "for the nonce" = "for the while being".

Marshall

@rak1507 Please write your answers in this dialog box.

ngn

@rak1507 2↑#

rak1507

@Adám must be an English idiom as I've never heard it

@ngn ah makes sense I guess

Adám

@rak1507 Dyalog 13.0: ∊#

rak1507

15:35

that's cheating

Adám

APL (Dyalog Extended), 2 bytes ⍷#

user

@Adám Just a plain domain error, but inserted into the session log those many seconds earlier?

Adám

@user Not only complicated to implement; I just want a harmless Easter egg addition.

If we can find a consensus, I'll try to get this actually implemented.

user

@Adám Oh, I thought it was just a discussion about what might be funny. Yeah, that would be a problematic Easter egg.

Adám

CMQ: Anyone up for creating a logo for the Safe Execute tool used by the bot, TryAPL, and the competition site?

I was thinking some amalgamation of ⍎ and a padlock.

ngn

15:40

that would be a good representation of how you treat the transparency of competition results

RGS

xD

Here we go again.

rak1507

lmao

Adám

@ngn Right, I need this to put on the competition site.

RGS

There you go, you are welcome.

rak1507

beautiful

tbf it's better than I could do

Wezl

15:42

@Adám ermineii.github.io/…

Adám

@RGS Can you try it without the keyhole?

ngn

@Adám what if you do get an email requesting transparency?

rak1507

oh no not again

Adám

@ngn Who says such transparency will be granted? At least we can display the logo until then.

RGS

Adám

15:44

@Wezl That's quite good, but maybe too subtle. Maybe try overlaying ⍝ and a mirrored ⍉?

ngn

@Adám i thought so

rak1507

what about ⍎ on a padlock

hang on

Adám

@RGS Maybe make the hoop curve inwards a little, to be more like a ∘?

@rak1507 Oh, you mean as the keyhole? Nice idea.

RGS

You mean like this?

rak1507

RGS

15:46

rak1507

something like this but done by someone who can actually draw

where the ⍎ is embedded in the padlock

Adám

@rak1507 What's up with the hoop?

@RGS That's good.

RGS

My take on @rak1507's idea prnt.sc/xdpu2t

rak1507

idk

yeah that works ok I guess

Adám

@RGS Yeah, that's nice too, but I actually like the idea of the base of ⍎ forming the bottom of the pad.

rak1507

15:47

what if it was further to the right

hang on

Adám

@rak1507 Is it open‽

But with connected lines.

rak1507

I don't know if this looks terrible or if I just can't draw

or both!

Adám

@RGS I think I like this one best.

RGS

prnt.sc/xdpz1b

Adám

Nice summary. Yeah, I like the centre one best.

Anyone able/willing to make an svg of it?

rak1507

15:50

yeah same

@Adám if you provide me a list of points I can use my bezier interpolation thingy! lol

ngn

@Adám for how much £? :)

Adám

@ngn I was thinking £0, but you want €, no?

ngn

лв. actually

Adám

I'll pay you all my лв.

ngn

i'll use all my drawing skill in return :D

dzaima

15:54

@Adám just a padlock with an ⍎ in it?

Adám

@dzaima Yeah.

dzaima

damn i've completely forgotten how to use my svg editor

ngn

maybe this €0 bill will remind you? :)

Wezl

@dzaima heh use vis/vi/vim

32x32 png favicon-size-ish lock, connected -- goya

Adám

16:11

I don't need a favicon though.

ngn

@Wezl that explains your avatar

Wezl

@ngn actually I made that in tic-80 , but goya is more convenient for exporting

Adám

OK, whomever sends me an SVG that I accept (subjective judgment, of course) will get a mention in the readme, and see their logo featured on the competition site.

xpqz

rak1507

that's cool is it automated?

@Adám please accept I worked very hard on this

Razetime

16:15

it looks hand drawn keyframed

xpqz

FlipaClip, iPad and an iPad pencil

rak1507

that's cool

Adám

Agreed, but maybe a tad busy for a logo.

xpqz

How about the glyph inserted half-way from the bottom, like a key?

ngn

🔒⍎ <- is there a way to put 2 unicode chars on top of one another?

xpqz

16:18

Although perhaps that's the wrong message.

Adám

@xpqz Can you sketch it?

ngn

some of these look more like shopping bags than padlocks

dzaima

true

Adám

@dzaima Almost there. Can you make the hoop a perfect circle, and maybe grow the ⍎ little (without increasing its line thickness)?

xpqz

16:26

Adám

@xpqz Beautiful, btw, but I was thinking the keyhole would be at the front.

Also, it doesn't make so much sense that ⍎ unlocks the lock.

xpqz

Aha, yes, perhaps that would be better.

No, that's perhaps the opposite message.

Adám

Would make more sense if the padlock was hooked into the ⍎'s loop.

Or around the | inside the ∘

xpqz

Is ⍎ the only restriction?

Adám

No, it is a locked down ⍎.

Actually, maybe a ⍎ in a safe would make more sense.

Or maybe simply a ⍎ in a box.

Wezl

16:31

sorry I can't see other's submissions, but here is mine

xpqz

Adám

@xpqz Yeah, but will be hard to "iconise".

xpqz

What is that symbol supposed to be, anyway? A map-pin spearing an olive?

dzaima

Adám

@Wezl I like it, but I think the relying on two-tone is too subtle.

rak1507

It also looks slightly like a door

Almost like a locked door which I suppose works too

Wezl

@Adám the colors come from my conCurr logo, copy-pasted and edited in VS Code for no particularly good reason

Adám

@Wezl If you increase the line thickness a little, and move the ⍎ into the lock, I might prefer yours.

Wezl

xpqz

Too subtle?

Adám

@xpqz Actually, the fire hydrant itself indicates emergencies, or safety. Maybe a stylised ⍎/fire hydrant hybrid?

@Wezl I kind of like the hard corners on your ⍎

@dzaima But I like it :-)

OK, now I'm just waiting for @xpqz to submit his contender for an ⍎/hydrant hybrid…

Wezl

dzaima's with square linecaps:

dzaima.github.io/paste/#0vZTPcpswEMbveood5UqN/…

dzaima

@Wezl I did try that, but the rounded corners mess with it (now that i think about it, just make square corners :|)

Wezl

very true -- and I don't have an svg editor so I can't

Adám

17:05

Oh, a joint submission.

rak1507

just you wait...

Adám

@dzaima Yeah, can you make Wezl's last version with the outer corners square?

dzaima

there

Wezl

count it as dzaima's, I did nothing

xpqz

Wezl

17:08

what is this?

xpqz

It was supposed to be eval viewed through a rifle scope.

Wezl

wow lol

RikedyP

@xpqz すごい！

xpqz

You speak Japanese?

RikedyP

@xpqz Not very well but I'm learning

xpqz

17:11

Japanese: when APL's too easy.

Wezl

I'd make a hydrant in a shield if I knew how to make bezier curves in svg

RikedyP

@xpqz The grey area is there, especially problematic in Phase I, but with Phase II I think the problems are involved enough generally that you won't solve it all by just chaining APLCart results together (I think/hope)

And I think it has been stated that simply copying library functions will get you marked lower than an equivalently good entry that doesn't

And also I stated earlier that you need to understand the problem and solution well enough, and express that through code + comments, such that we understand from reading it that you understand

And also if you win you'll be asked to do a presentation, so if you come and your presentation is "I dunno, I just searched APLCart and glued it all together" you'll have probably the worst winner's presentation yet

xpqz

Wow, context switch :)

RikedyP

@xpqz Sorry I only just saw your message from earlier

@xpqz It's a shame the characters look a bit pants in the IDE. Not too bad in my RIDE tho

xpqz

No, I agree. I just pondered this when solving the propsoed Phase2 set that some of them shrank down to a Phase1 size with a bit of 'dfns' know-how -- which is good stuff as an APLer, right? But perhaps not what the competition was after.

Adám

17:18

@Wezl You gave the hard corners.

Wezl

@Adám no dzaima did. I just changed round -> square or butt

Adám

Oh.

dzaima

@Wezl you thought of using them, and you also inspired the whole door design

Adám

@xpqz Are you going to submit a serious contender or shall I go with with the Wezl/dzaima one?

Cute.

Wezl

@dzaima Adám thought of them :|

dzaima

@Wezl "on your ⍎". All Adám did was like them

Adám

@dzaima Hard work.

rak1507

@Wezl :) plot points, use bezier, ez

Adám

I'm always confused about this. How to I crop an svg?

Changing the viewBox always seems to do counter-intuitive things.

Wezl

17:25

@Adám change <svg
xmlns="http://www.w3.org/2000/svg"
width="HERE"
height="HERE"
fill="white" >

Adám

@Wezl No, that just scales it.

dzaima

@Wezl my svg is offset to some random coordinates, so that doesn't help much

Razetime

@xpqz executing the executor i see

dzaima

a bit cropped:

Adám

Perfect.

Wezl

17:28

yah, I guess if you want to manually do it (you don't), you edit the viewBox

plug: you can download it with the button here

ermineii.github.io/paste/…

xpqz

@Adám I'm out of creative juices; go with @dzaima / @Wezl

rak1507

@Wezl did you fork dzaima's paste or did dzaima fork yours?

I assume dzaima's was first

Wezl

it was

I'd pull request but my editor messed everything up by formatting the html and it would have to be manually merged

also I think I'll add svg as a language to make pasting more convenient

xpqz

@RikedyP I translated your kanji. Either "wonderful", "terrible", "dreadful" or "great".

dzaima

@Wezl it also occurred to me that there's no plain text language. ¯\_(ツ)_/¯

and svg should probably be called "rendered svg" to be clear

Wezl

17:40

yeah I'm not up to making an xml highlighter

dzaima

:D

Adám

Heh, Dyalog has one built in, but I don't think it can be accessed.

Oh wait, it can.

xpqz

@Adám wait, you have what built in?

Adám

Ability to syntax highlight XML

xpqz

In the interpreter?

Adám

17:41

Yes.

xpqz

That's crazy on so many levels :)

Adám

I am using the built-in syntax highlighter for APL in my code to sanity-check phase II submissions this year.

Wezl

@Wezl wow, that was exceptionally easy

dzaima

@Wezl yeah, not much more that'd need

though why genc = …? That breaks things

Wezl

@dzaima also speaks to the readability that paste is so easy to contribute to

@dzaima IDK I just pasted from the JS on your SVGs

dzaima

17:49

@Wezl none of mine do genc =

Wezl

oh I must have found it some other way. genc = doesn't even look like it would work

I guess I put genc = without thinking about it

dzaima

i feel like you began typing it and then decided to just copy-paste or something

also you probably want to add white-space: nowrap; to the style of the id="ddm" div for the name to not wrap in the lang dropdown menu (html/css :|)

Wezl

exactly what happened, now it's fixed

Wezl

18:08

perhaps it should be Rendered HTML because the pasted content doesn't have to be an svg

dzaima

@Wezl I was thinking of having both, for the download button to give the correct file type

Wezl

It's very easy to make a valid embedded svg that's not a valid standalone file by omitting some XML stuff, I think

dzaima

eh yeah

blame the user :p

Wezl

this fails as a file

dzaima

¯\_(ツ)_/¯
