10:00 AM
Umm... what?
 
Exactly
 
@Qwerp-Derp ^^ nope
 
^ That should be 3 ^'s
 
This word don't exists
 
@Qwerp-Derp Quince is related to sequences! :D :) :| :/
 
10:01 AM
C. Quince
Sequence
Ah ah geddit?
It's a good name don't judge me
5
 
@seequ Oh come on, now I want to make a Gomix-based network
 
Can someone come up with a hipster syntax
 
Something like Elixir?
(I'm actually loving Elixir)
 
Elixir's syntax is bad IMO
 
exactly
 
10:06 AM
Wait what
Confuse
Elixir code:
for n <- [1,2,3,4,5], rem(n,2) == 1, do: n*n
What the heck is this
 
It's very much a hipster syntax
 
Elixir: I already hated it from ground top.
 
It's just slightly better Erlang with an odd syntax.
 
(for [x (range 5)]
  (if (= (mod 2 x) 1)
    (* x x)))
Same thing in Clojure
 
(for [x (range 5) :when (= (mod 2 x) 1)] (* x x))
 
10:09 AM
Apparently Elixir was inspired by Clojure
Indent code with 4 spaces
 
@seequ Which parts of the Matrix spec do I need to make a server program?
 
@seequ For multi-line code, add 4 spaces before each line, and use Shift+Enter for newline.
 
Also you're missing an end bracket
 
@Qwerp-Derp Wat?
 
Bleh
 
10:10 AM
@TuxCopter Elixir
 
Oh wait
 
The Elixir code is correct
 
Why is Elixir even a thing with its horrible syntax
 
n <- [1, 2, 3, 4, 5] iterates on n, rem(n, 2) == 1 is a condition
Finally it's (half) logic
 
It's just an iterated syntax for Erlang's list comprehension
 
10:11 AM
Still this syntax is just horrible
 
Yeah, but it's not so bad that it's a problem
 
@seequ What what what what
Nope nope nope nope
It's just... bad
 
heh
Well the other choice is Erlang
How do I indent a code snippet?
 
Extra spaces after the code-indent 4 spaces
 
There was a hotkey for it
 
10:15 AM
@seequ You can also make a multi-line snippet (not single-line) and then click "fixed font", and then send.
 
fib(1) -> 1;
fib(2) -> 1;
fib(N) -> fib(N - 2) + fib(N - 1).
WTH is this Erlang
Please stop
 
  defp handle_room_updates(rooms, token) do
    for {room, room_data} <- rooms, evt <- room_data["timeline"]["events"] do
      case evt["type"] do
        "m.room.name" ->
          State.update(fn state -> put_in(state.rooms[room].name, evt["content"]["name"]) end)
          EventBroker.send({token, :room, :name, room, evt})
        "m.room.message" ->
          EventBroker.send({token, :room, :message, room, evt})
        _ ->
          nil
      end
    end
    :ok
  end
 
TBH I can probably improve this

Q: Best of PPCG 2016 — Call for Categories

Martin EnderLast year we voted for the best posts of 2015 and rewarded them with bounties and challenges. I think it's a great way to reward and draw attention to some of the best content the community has created throughout the year, so let's do that again. (And hopefully, this year, we'll be able to sort e...

 
@Qwerp-Derp No, that's the most idiomatic Erlang
 
10:17 AM
fib -> n [
    1: 1,
    2: 1,
    fib(n - 2) + fib(n - 1)
]
What do you think of this syntax
 
@NewMetaPosts Holy smokes, did you have too much coffee this morning?
 
fib->n[1:1,2:1,fib(n-2)+fib(n-1)]
Golfed
 
Anonymous
@MartinEnder Can we feed it coffee through an IV so it will actually post on time?
 
@Qwerp-Derp Okay, how does it work with multiple arguments?
 
a->m,n[(m|n)<0:-1,m+n]
That's how it works
 
10:19 AM
(Oh no, Martin is here. I better hide asap)
 
And you're saying that's cleaner? :P
 
add -> m, n [
    (m | n) < 0: -1,
    m + n
]
That's better right
Keep in mind CMQ is only based on sequences with numbers
 
I wouldn't say so, but it's subjective.
 
| is OR, BTW
 
Oh, so you're talking about a new syntax
 
10:20 AM
Yup
 
for a new language
okay
 
Does that look clean?
 
No.
 
Does it look readable?
 
No.
 
10:22 AM
Why?
 
I don't know the syntax and haven't yet studied it :P
 
@MartinEnder So just answers or questions on the main are elligible?
 
@flawr what else?
 
Anonymous
It's not like we can slap a bounty on a review queue :P
 
Anonymous
Though that would make an interesting feature... Unfortunately, it would likely make matters worse - people would try to blast through the queue to get the rep faster, with less effort.
 
10:25 AM
add(m, n) when m < 0 || n < 0 -> -1,
add(m, n) -> m+n.
 
@seequ If either m or n is less than 0, return -1. Else, return m+n.
 
I'm just trying to clarify. Why not vote for the most helpful comment? Or the most controversial chat topic? (<- not very serious)
 
Anonymous
@flawr Comments are transient. The most helpful comment may not even still exist by the time voting comes around.
 
You can delete answers or challenges too.

Good morning 19th byte, so you're all good at golfing, golf me a description of PPCG in one sentence at most (its for a presentation so be creative)

Kinda creative, surely short.

Too vague, sorry. Grade: F×22
 
@seequ Can anyone top 3 bytes?
 
@7H3_H4CK3R I can if you'd like, in 2 bytes.

@ErikGolferエリックゴルファー well it is morning here, also go ahead. 2 bytes
 
fn
 
its a tie
is the standard tiebreaker the earlier answer?
 
No, fn doesn't make sense at all (it can mean function), CG can mean Code Golf.
 
i guess so

@Sp3000 but very accurate
 
Screw creativity, I just wanted to go with something that would actually make sense to anyone not familiar with the site :P
 
What if someone tries to solve a real-life problem using bytes? I don't think everything is solved with bytes.
 
Is anyone here into a "check my code without running it" question?

A: Sandbox for Proposed Challenges

Rudolf L. JelínekEffective street lighting code-golf You are the operator of a town's street lamps. Each road can have one or more lamps. When it's night, every part of the road must be lighted, eg. Either the lamp above it, or both lamps next to it must be on. Your job is to light all the streets in the most...

 
@zyabin101 a) that's an asynchronous callback and b) you're not even using rawManifest
 
If not, how can I make it?
 
But yes, it will.
 
Thanks.
 
12:04 PM
But do note that the callback is run at some point later.
 
@seequ I will, soon. I dismissed the part where it'll be used, but I will parse the TOML content and validate the manifest.
 
It seems like you either want futures or fs.readFileSync
 
@seequ I think readFileSync takes the same parameters as readFile, yup?
@NewSandboxedPosts @n4melyh4xor The requirement is subjective.
What should I do to look as close as the lang name?
 
ah ok, sorry, didn't mention that
 
I'd easily submit Python=2 or Python=3 with both having a diff of 1 character.
Next question: how do I check if the entirety of a name matches a regex?
 
12:17 PM
hi
 
(Node.js, as you can see)
 
Got it.
@zyabin101 what do you mean?
the challenge is based on the lowest score
 
@n4melyh4xor For example, ABCD entirely matches the regex [A-Z]+, but A8CD doesn't.
The former is accepted, the latter isn't.
 
aren't alphanumeric characters also 0-9+ space + _?
 
@n4melyh4xor And, for my purposes, also - and ..
 
12:21 PM
so AB8D is valid
it's a thing composed entirely of alphanumeric characters
 
Oh, I got it:
412
A: Check whether a string matches a regex

user113716Use regex.test() if all you want is a boolean result: /^([a-z0-9]{5,})$/.test('abc1'); // false /^([a-z0-9]{5,})$/.test('abc12'); // true /^([a-z0-9]{5,})$/.test('abc123'); // true ...and you could remove the () from your regexp since you've no need for a capture.

 
@zyabin101 ah, I thought you were talking about the challenge!
okay then

A: Best of PPCG 2016 — Call for Categories

zyabin101Best Above-and-Beyond Answer This was originally featured in Best of 2015 by PhiNotPi. Every once and a while, an answer takes the challenge to the extreme. This prize will be awarded to an answer which went far beyond the expectations of the challenge. This could include a code golf...

 
Can you give bounties to questions?
ie to the person who wrote the challenge not the answerers
 
@KritixiLithos You can't, but you can give a bounty to the best answer of the person who asked this question.
I can't contribute 500 rep exactly (y'know, privileges are important, too), I can contribute 100 rep maximum, I will contribute 50.
But someone else can fill in the remaining 450 rep.
 
1:49 PM
Unfortunately no
 
No one wants to fill in the 450 rep? :E
 
It's because you can only give bounties in 50, 100, 200, 500 rep each AFAIK
 
Fun fact: The human brain was not designed to handle continuations
 
@El'endiaStarman well not quite, seeing how long it took to sort out all the prizes :P
 
@KritixiLithos No, you can give bounties in the full range(50, 500+1, 50).

@n4melyh4xor You make too many of those jokes.
 
Basically it's lots of inb4 I guess? inb4 is actually a thing, google it. Also, a lot of times it's inb4 banned.
 
Quote from new challenge I'm writing:
> # Golf a polyglot binary quine
 
"binary"?
 
> A program is a binary quine if the program outputs its source in binary when run (in your preferred encoding). For example, the submission aaa should output 011000010110000101100001 if the author specifies the encoding as UTF-8.
There, I added quotes around binary quine in the title.
 
The main point here is: don't intentionally flout the chat rules. TNB in particular has the Chatiquette, which was created because TNB filled up with noise to the detriment of good conversation and the loss of some good participants. Stuff like inb4 banned are against the Chatiquette because it doesn't add anything of value to TNB.

I'm pretty sure the interpreter won't check until you reach the invalid character, but I'd have to try to be sure

@Downgoat Does your TIO desktop app use Nativefier, or Electron? :3
 
@TuxCopter because it use electron under the hood
 
("IF?! *starts letting you know*")
 
@Downgoat Electron, which is a desktop wrapper for node
 
3:45 PM
@TuxCopter Yes, it allows you to make desktop apps with Node.
 
@Downgoat the thing that Atom uses?
