@cairdcoinheringaahing Unfortunately some people don't realize that the thing with CR is a joke, and cause problems

2EZ 4RTZ

Yeah idk who would do that.

@Dennis does a suspended chat user still see pings?

Dennis

@2EZ4RTZ Not sure. Probably.

2EZ 4RTZ

@Dennis huh interesting. BTW jelly confuses me.

Why no order of operation modifiers?

Downgoat

> but it shows how slavery could sometimes be beneficial.

my history book is messed up

it says this in context of a man who learned how to paint after getting enslaved :|

Dennis

:39927391I have no idea what you mean.

2EZ 4RTZ

00:16

@Dennis Using () to modify the order that code is run it would make my life ez

IE 2*(R(2**n))

Dennis

And how would you parse the chain inside the parens? Niladically? Monadically? Dyadically? Something else?

2EZ 4RTZ

Yeah that makes sense, OK! Ty for letting me know what was wrong with my idea (knew something had to be wrong with it)

ATaco

01:04

@2EZ4RTZ I'm assuming this should only work in TNB?

Pavel

@ATaco Can it not require the /? I want to see all CMCs, not just those by people with the userscript.

ATaco

I can make it not require it, but it may pick up people just mentioning CMC:

HyperNeutrino

How about /[*_]*CMC[*_]*:.+/i

Draw my Contours code-golf matrix Given a rectangular matrix of elevations, draw its contours. Task Two elements x and y are on the same contour level if floor(x/10) == floor(y/10). For example, 52 and 58 are on the same contour level, but 58 and 64 are not. The act of drawing contours is ...

Pavel

@HyperNeutrino [*_]?

HyperNeutrino

01:09

@Pavel bold/italic

Pavel

Ah.

How about this regex: /^[*_\s]*CMC|\/[*_]*CMC/i

ATaco

/^(@\w+|:\d+)?\s*[*_]*CMC/ is probably better.

Pavel

If there's a /, always treat it as a CMC, otherwise only at the start of a line.

I don't believe a colon should be required.

ATaco

/(^(@\w+|:\d+)?\s*[*_]*|\/)CMC/

Pavel

And at that point I can no longer read it.

Remember to check for :\d+ replies though.

ATaco

01:12

Come on, it's just a little Regex :P

I do that.

Honestly I don't know why I thought that might work.

Pavel

Sometimes I have a thought that regex might not be the right solution. I proceed to slap myself and the thought goes away.

HyperNeutrino

So like check to make sure it starts with a slash or optionally a ping/reply and then arbitrary spacing, and then might start with *_**_*_*_*__*_ etc

c'mon that's not that confusing :P

Also feature-request add a /RTL command to place an RTL control character :P

Actually don't because that just makes RTL trolling easier

Pavel

@HyperNeutrino That's simple enough to write into your own version of the script

HyperNeutrino

yup :P

ATaco

regex101.com/r/2vFnSB/1

It's not that complicated :P

Pavel

01:19

@ATaco You forgot to add the i flag

ATaco

I don't want to match cmc:

Pavel

Why not

Also some people have unicode in their name, \w isn't sufficient.

ATaco

\S is a nice copout solution.

Pavel

Yep

miles

CMC: given a boolean array and string both of equal length, partition the string at the end of each truthy value in the boolean array: [0,1,0,0,1,1] and 'abcdef' -> ['ab','cde','f']

Pavel

01:22

By the way, with the x flag, you can do #comment instead of (?#comment)

HyperNeutrino

@miles is this a Jelly builtin

œṗ?

oh rip not exactly apparently

miles

@HyperNeutrino that goes from the start of each truthy value, and includes an empty partition as the first value

HyperNeutrino

gosh darn it

miles

@Dennis what was the rationale for including an empty partition at the start for œṗ (partition and keep borders)

HyperNeutrino

darn apparently UœṗUU doesn't work either :P

@miles i don't think it does?

miles

01:27

@HyperNeutrino tio.run/##y0rNyan8///o5Ic7px@d9HDnjP///xvqGOgYAqHB/8Sk5JRUAA

HyperNeutrino

o huh apparently L doesn't count that

oh wait it does

oh uh that only happens if the first value is truthy

which makes sense because you're making a partition from index 1 to index 1 which is just the empty list

ATaco

RProgN2, 17 bytes. sy=ix={x‘³)y’?};y

Dennis

@miles It only starts with an empty partition if you start with a truthy value.

HyperNeutrino

oh huh I was right for once

Jelly, 10 bytes: T;@0r2\Ḋ€ị

miles

I see, so I'm just used to thinking in terms of J's partition which excludes the partition before the first truthy value.

Dennis

01:34

In retrospect, that might have made more sense.

miles

@HyperNeutrino gj, but you can get down to 5 bytes

HyperNeutrino

@Dennis TIO-request: Make a CMC copy-paste format option in the format #language#, #bytecount# bytes: [#code#](#url#)

@miles thx and o cool brb golfing now :P

ATaco

This is like, the 90th time that's been requested :P

Pavel

@miles Can I print each partition on it's own line, and assume that the input string doesn't contain newlines?

HyperNeutrino

@ATaco o :(

miles

01:36

I was just wondering since I'm probably going to add the ;. family of conjunctions next to Jelly, just wondering how to spread them out and combine some. Can never have enough looping constructs

HyperNeutrino

@miles hints for <10 bytes?

miles

@Pavel the input will only be [a-z] or [A-Z], and formatting the output doesn't count towards your byte total

Pavel

I just need a way to seperate partitions

miles

@HyperNeutrino see the new quick I added ƙ

Pavel

Would taking the input transposed into tuples be too much too ask?

HyperNeutrino

01:41

@miles oh so I was supposed to use that? :P I thought it wouldn't help me here

miles

yeah, that's a bit much, they're meant to be interpreted as the boolean array being the control for the partitions on the string

HyperNeutrino

@miles wait huh? how exactly does the new quick work I don't get it

Oh I see it doesn't do runs of equal elements it just puts them into "buckets" o I see

miles

@HyperNeutrino it takes a monad and creates a dyad that groups the items of the RHS based on the classes of equal items on the LHS, then applies the initial monad to each group

HyperNeutrino

So it applies the monad to the group of RHS elements, which makes the LHS elements ignored when the monad is processed?

So like

lambda monad: lambda left, right: [monad([right[i] for i in range(len(right)) if left[i] == value]) for value in set(left)]

?

(lol terribly inefficiently one-lining Python programs to explain things)

I'm confuzzled as to how that helps me for this problem though @miles

Pavel

@miles C#: l=>t=>{var i="";return t.Zip(l,(a,b)=>{i+=a+(b==1?1:0);return 0;}})return i.Split("1");}

HyperNeutrino

01:50

@miles halp I don't get how to use this thingy D:

miles

@HyperNeutrino yeah the monad doesn't operate on the LHS, only on the groups of the RHS. The quick only uses the LHS to form the groups from the RHS

HyperNeutrino

ah ok thanks

but I don't get how this helps for this CMC D:

@miles ^

miles

02:09

@HyperNeutrino you want to transform the boolean array into runs of equal values to make it work with key

HyperNeutrino

huh I'm confused as to how to do that rip

Œg?

miles

for example, [0,1,0,0,1,1] could become [0,0,1,1,1,2], but it could be any value there as long as they are exclusive to that partition

HyperNeutrino

oh I see

ATaco

02:39

Serverside half of the CMC widget is done.

Pavel

Oooh

@ATaco TeamSpirit is bork and has been for a few days, it's constantly been showing ?/?

ATaco

Hmm, that's interesting.

I've had TeamSpirit off for a while.

ATaco

03:27

@2EZ4RTZ Alright, I've created the CMC widget which as usual can be downloaded from Github or A-ta.co

@Pavel CC ^

(The /CMC functionality is turned off temporarily because of the amount we've used it recently)

Pavel

CMC: Given a list of numbers, [a, b, c, d, e, f...], output a×b÷c×d÷e×f...

ATaco

(Oh, the list is upside down)

Pavel

@ATaco feature-request make the little reply button change your cursor to the hand thing when you pass over it

ATaco

(Oh I thought I fixed that)

Pavel

Also, how do I use MathQuil?

ATaco

03:33

Type a $

Downgoat

@Pavel JS: a=>a.reduce((a,b,i)=>i%2?a/b:a*b)

@Pavel btw can u provide example test case

Pavel

2, 4, 8, 3 => 3

Downgoat

fixed: a=>a.reduce((a,b,i)=>i%2?a*b:a/b)

ATaco

@Pavel Patched :D

Downgoat

@ATaco can you make MathQuill start thing $$ so I can paste things which have $ in them :3

Pavel

03:41

@ATaco Neat

ATaco

04:08

@Pavel RProgN2, 22 bytes. ix=x‘xi{0#/#*?10-`0=};

@Downgoat Is Caretreply still borked?

Pavel

@ATaco works for me

Pavel

This is the fewest people I have seen in TNB, ever. The "Currently in room" display usually shows at least 3 rows, most times 4

@El'endiaStarman Hi, I have a TNBDE/SQL question for you. How do I get every column in the "transcriptAnalyzer_message" with GROUP BY user_id and ORDER BY mid DESC? Everything I've tried so far has run into errors

caird coinheringaahing

06:22

@2EZ4RTZ I can tell you first hand that they do

Sherlock9

06:58

Okay figured it out thanks to this: stackoverflow.com/questions/3800551/…. This is what I have so far: ppcg.starmaninnovations.com/tnbde/#vnJfjScuzQ

Erik the Outgolfer

@Pavel it has 2 rows a lot of times

Pavel

@EriktheOutgolfer Well, now there's two rows.

There was like 2/3s of a row an hour ago.

Erik the Outgolfer

an hour ago there was also me having to stand for a long time at school so a priest can "bless the school"

really got dizzy to that

Fatalize

07:16

Too bad his prayers didn't prevent the storm from forming in the first place

Strange isn't it

Pavel

iirc Erik lives in Greece? I don't really remember.

Fatalize

Oh yeah right

Got confused because I had seen a video of people praying on the beach against Irma

Erik the Outgolfer

@Pavel yes

@Fatalize let's say I was praying for the end of the praying there to come

afterwards there were municipality officials saying a word...man it keeps so long

and the usual stuff "This day marks..."

then I got the books...they were heavy to carry back to home

Fatalize

07:34

Is it a public school?

Erik the Outgolfer

yes

general high school, class A

the principal divided us alphabetically :p

it's what we usually call "grade 10"

at least last year I completed mandatory education :)

Fatalize

Glad I live in a country where public schools are forbidden to express any religiosity

@EriktheOutgolfer That's… a weird way of creating classes…

Could leave to very heterogeneous groups

Erik the Outgolfer

@Fatalize what do you mean? we don't separate between male and female

@Fatalize you can exempt from religious education if your parents agree to

Fatalize

I mean all kids with bad results could end up in the same class

Erik the Outgolfer

umm, that's just by chance though isn't it? unless they divide by historical performance

Fatalize

07:41

@EriktheOutgolfer That's not enough. I wouldn't go to a school that offered religious education in the first place

Erik the Outgolfer

@Fatalize I use religious education for easy grades ;p

not that I believe everything they say

nor that I believe everything THEY say in the history book to try to brainwash us and make the next generation of people who believe in propaganda and vote for the parties that are betraying the county and hide the truth

and I believe in greece public schools teach religious education because we have an official religion (Orthodox) or something

through religion also comes brainwashing too

it's like they use peoples' beliefs to brainwash them

Erik the Outgolfer

08:39

this seems wasteful...

especially the prefixes (p="...")

hi

Mr. Xcoder

@EriktheOutgolfer Hi, how's school there?

Erik the Outgolfer

bad as usual

Mr. Xcoder

Yeah, expected that answer

It was a waste of time today (here)

Erik the Outgolfer

yeah the blesses and book carrying

Mr. Xcoder

We don't carry books in the first day... It's even worse (we get them at the end of the year instead)

And i am quite sad cuz a great teacher left us :((

Erik the Outgolfer

09:17

they died or just left?

Mr. Xcoder

@EriktheOutgolfer Left :)

Erik the Outgolfer

oh

right

Mr. Xcoder

Sorry for the very late response

Erik the Outgolfer

because last year a teacher of mine did die of cancer

(that is, middle school back then)

Mr. Xcoder

@EriktheOutgolfer Sorry for your loss (?)

We've "lost" (they still live) some great professors over the years, but none of the bad professors ever left

Still, the greatest are with us.

Erik the Outgolfer

09:21

@Mr.Xcoder she wasn't from my family, although I still respect it

she was fighting cancer for many years...

Mr. Xcoder

And BTW one of the best Physics professors in town died of cancer 2 years ago

Her son was a gold medalist at the international science olympiad, twice

Erik the Outgolfer

sorry

Mr. Xcoder

Yeah, that shocked the entire school

yay my reputation is palindrome again!

Mr. Xcoder

10:03

If anyone is around, CMC: Given a matrix, get the prefixes of its columns

[[1,2,3],[4,5,6],[7,8,9]] -> [[[1], [1, 4], [1, 4, 7]], [[2], [2, 5], [2, 5, 8]], [[3], [3, 6], [3, 6, 9]]]

4 bytes for sure in Pyth.

Erik the Outgolfer

3 bytes for sure in jelly

Mr. Xcoder

@EriktheOutgolfer How?

Erik the Outgolfer

wait

what are you asking?

Mr. Xcoder

I currently have 5

Erik the Outgolfer

4 bytes in jelly

Mr. Xcoder

10:07

4 bytes

@EriktheOutgolfer Z¹Ƥ€?

Erik the Outgolfer

yes

ninja

Mr. Xcoder

ninja-ninja'd

Quite bad that you have to do prefix-identity to get the pure prefixes

Erik the Outgolfer

husk, 5 bytes

Mr. Xcoder

Let me solve it in 05AB1E then. Brb solving in Husk first

Erik the Outgolfer

darn empty prefixes

Mr. Xcoder

10:10

Meh... Yeah

@EriktheOutgolfer We should ask Zgarb or Leo to remove those

Erik the Outgolfer

already done

Fatalize

@Mr.Xcoder Brachylog, 7 bytes: \{a₀ᶠ}ᵐ

Mr. Xcoder

@Fatalize Nice. What is the part that extracts the prefixes?

Erik the Outgolfer

@Fatalize yeah a bugfix would be nice to bring to 5 :p

Fatalize

a₀ is prefix (a for adfix)

H.PWiz

10:12

@EriktheOutgolferEr I'm on mobile, so can't check, but I think G (with a dot) : gives prefixes

Mr. Xcoder

I've been trying to solve some prefix related stuff in Brachylog lately

Fatalize

a₀ᶠ is find all prefixes

Erik the Outgolfer

brachylog isn't very good with prefixes...

Fatalize

{…}ᵐ maps and `\` is transpose

Erik the Outgolfer

``\``

Mr. Xcoder

10:13

@EriktheOutgolfer This is your 5 byter: motḣT

I guess

Erik the Outgolfer

of course

Mr. Xcoder

@H.PWiz What do you mean?

Erik the Outgolfer

@H.PWiz it doesn't?

error

it actually accepts a function as its argument

x -> y -> y

and it returns a function

Mr. Xcoder

@Erik 3 bytes in 05AB1E.

Erik the Outgolfer

y -> [x] -> [y]

@Mr.Xcoder ø€η right?

Mr. Xcoder

10:16

øεη yes.

technically, it is identical

Erik the Outgolfer

no

practically it is

in this case

Mr. Xcoder

Yeah. It's like abusing implicit }

Erik the Outgolfer

but € and ε work a bit differently

Mr. Xcoder

I know

Erik the Outgolfer

it's not just that € accepts only one command while ε accepts more

Mr. Xcoder

10:17

But in this case

Well, the latter is apply each on a

Whilst the former is for each

@EriktheOutgolfer What else?

Erik the Outgolfer

well, the former kind of splats the resulting stacks

while the latter picks the top element of each stack

Mr. Xcoder

Brb solving in Pyke

3 bytes.

4 bytes, in fact

3 bytes again

Erik the Outgolfer

05ab1e example

Mr. Xcoder

@EriktheOutgolfer yep, nice explanation

2C 46 BE in Pyke (hehe, I love those hex encodings :)) )

@EriktheOutgolfer I challenge you to solve that in Python now

In Python 2, I have 58 bytes

LegionMammal978

Huh, rain just started passing through my area (North Georgia)

monring btw

Erik the Outgolfer

10:26

@Mr.Xcoder me too

Mr. Xcoder

@LegionMammal978 Hello

Erik the Outgolfer

lambda x:[[i[:j+1]for j in range(len(x))]for i in zip(*x)]

Mr. Xcoder

Yes, lambda m:[[r[:i+1]for i in range(len(r))]for r in zip(*m)]

A few characters away

@EriktheOutgolfer should that i[:i+1] be i[:j+1]?

LegionMammal978

@Mr.Xcoder Hello, kind sir, I hope you have had a most excellent morning this day

Erik the Outgolfer

@Mr.Xcoder sure

Mr. Xcoder

10:27

@LegionMammal978 Thanks a lot! Unfortunately not the best morning ever because it is the first school day >.>

Erik the Outgolfer

@LegionMammal978 Sorry to interrupt kind sir, but I do appreciate your kindness

LegionMammal978

@Mr.Xcoder Would be the start of the sixth week here, but they cancelled it for 2 days due to the hurricane

Erik the Outgolfer

However, I've been through not the best of times

LegionMammal978

We're only projected to get a few inches of rain

Mr. Xcoder

@LegionMammal978 Hurricane in Georgia?

LegionMammal978

10:30

@Mr.Xcoder Hurricane(/future tropical storm) Irma

Mr. Xcoder

Oh.

LegionMammal978

Came up from Florida, will be going to Alabama

Mr. Xcoder

I know of Irma lol

Erik the Outgolfer

the whole world probably knows of irma

Mr. Xcoder

@LegionMammal978 Oh the state Georgia... I thought it was the country Georgia lol

LegionMammal978

10:31

Yeah, there's literally nothing else on the cable news channels :P

@Mr.Xcoder Yeah, been trying to find a good noun clause to indicate "the northern section of the U.S. southeastern State of Georgia"

Mr. Xcoder

I now feel good I am too young to not be interested about news :-)

LegionMammal978

I mean, I haven't had cable TV for years by this point, but was at a restaurant the other day

Mr. Xcoder

I think television is a waste of both time and money

Erik the Outgolfer

@Mr.Xcoder waaaat?

LegionMammal978

The only two topics there were "Hurricane Irma" and "medication commercials"

Erik the Outgolfer

10:34

that's where EAS resides

Mr. Xcoder

@EriktheOutgolfer What waaat?

LegionMammal978

True, EAS

Erik the Outgolfer

@LegionMammal978 the latter is telemarketing right?

Mr. Xcoder

I like watching stuff on the internet

Erik the Outgolfer

EAS isn't on the internet afaik

LegionMammal978

10:35

@EriktheOutgolfer No, like regular TV commercials, but for random medications

Erik the Outgolfer

even though if you have a phone you get a warning message from your provider

LegionMammal978

And it's on all the radio stations, too (at least in my area)

Erik the Outgolfer

@LegionMammal978 it's like more people will flock towards the medications because they saw the commercial event though they might not even be sick at all

LegionMammal978

@EriktheOutgolfer Nah, just a bunch of mutually unrelated stuff for chronic disorders and the like

All with random stock footage, though

Mr. Xcoder

@EriktheOutgolfer On a slightly unrelated note, did you manage to solve the last CMC caird posted on JHT?

LegionMammal978

10:38

@Mr.Xcoder ?

Mr. Xcoder

@LegionMammal978 Sorry, forgot to ping erik

@LegionMammal978 BTW JHT = Jelly Hypertraining

Erik the Outgolfer

it's for learning jelly

apart from the tutorial, that is

LegionMammal978

huh

Mr. Xcoder

bye!

@erik just ping if you get to 5 bytes (or lower?) too, if you solve it

I got around it by changing // @match *://chat.stackexchange.com/* to // @match *://chat.stackexchange.com/rooms/240/* but I'm no expert so I don't know if that'll cause any further problems.

Shaggy

@TheLethalCoder It hasn't been working for me at all since Chrome was updated to v60 possibly before).

TheLethalCoder

@Shaggy I am on Chrome v61 so maybe that affected it as well. It seemed to be fine on friday and then I opened up chat over on scifi today and it was bugging out.

I turned off the script and it was fine again

Although after editing the script with the more restrictive match it's fine again. I haven't had any other problems with it though.

Shaggy

@TheLethalCoder Now that I look into it more, none of my userscripts are working - looks like the problem is with TamperMonkey. Gonna try reinstalling it.

Aha, that was the problem - sorted now. No problems viewing any other chats, though. Which version of the script are you running?
