@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?

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.

@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

@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

A: Sandbox for Proposed Challenges

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

1:09 AM

@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

1:12 AM

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

1:19 AM

@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

1:22 AM

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

1:27 AM

@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

1:34 AM

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

1:36 AM

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

1:41 AM

@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

1:50 AM

@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

2:09 AM

@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

2:39 AM

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

3:27 AM

@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

3:33 AM

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

3:41 AM

@ATaco Neat

ATaco

4:08 AM

@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

6:22 AM

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

Sherlock9

6:58 AM

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