@DrGreenEggsandIronMan I'd reccomend node 4.4.5 as that's what I've developed on
 
Oh, Too late.
Although it's running, so that's good!
 
eh, 6.2.1 should work still :P

> cheddar>
wat do?
 
tyep chedr coed
 
@DrGreenEggsandIronMan Enter expressions into the cheddar> prompt, and Cheddar will evaluate them.
 
6:11 AM
e.g. print "2+2=" + String::(2+2)
wait, how did you install?
 
The result will be returned as output on the screen.
 
did you install from release-0.1a or master?
 
git clone github.com/cheddar-lang/Cheddar.git
cd Cheddar
npm install
grunt build --minify
All from regular windows prompt
 
okay, you're gonna have to do it a little differently for beta testing:
git clone -b release-0.1a github.com/cheddar-lang/Cheddar.git
cd Cheddar
npm install
grunt build --minify
there, run that
 
@DrGreenEggsandIronMan Wait, wat?
 
@DrGreenEggsandIronMan well now you have a bug to report
 
Do you want to switch to the cheddar room to not clutter up TNB?
 
yeah, lets do it before alex elevens us again

 Cheddar

For discussion of the design and development of the Cheddar pr...
 
Yeah, that was a lot of text.
I deleted though.
 
@Upgoat ?
 
6:16 AM
@zʏᴀʙiɴ101 Yes, I did it from a regular windows prompt
 
How could you install Cheddar from the regular Windows prompt? o_O
 
¯\_(ツ)_/¯ Which part do you think wouldn't work?
 
6:33 AM
CMC: Given x and n where gcd(x,n) = 1, find smallest p such that x^2p - x^p = 1 (mod n).
Edit: Given x and n, find smallest p such that x^2p = x^p (mod n).
Testcases: 7,10 -> 4; 8,10 -> 4
 
Have a little respect for yourself and your goddamn craft and download the gif to attach to the tweet. None of this direct link garbage
 
Yeah, it shows up very crappily on chat.

>_> omg just released cheddar first release. Just gotta tag & doc now
 
\o/ Congratulations @Upgoat on actually releasing Cheddar! \o/
 
7:08 AM
Just drafting the release. What should it say?
 
@Upgoat Initial release
Codename Cheddar.
 
@zʏᴀʙiɴ101 for the title?
 
@Upgoat "Initial release" for the title.
 
I liked "Codename Cheddar" for the initial title >_>
 
@Upgoat Okay, do "Codename Cheddar".
TODO: Next time, find more cheese sorts.
 
7:12 AM
does it sound cool to you to? :P I could always just do Cheddar v0.1 alpha
 
@Upgoat Okay, do "Cheddar v0.1 alpha".
And put "Codename Cheddar" in the release notes.
Or vice versa.
@Upgoat Well, when you finish the release, could you come to the zyabinVI beta room?
 
time to get some stickers made @Upgoat
 
@Quill omg yes
@zʏᴀʙiɴ101 haha, it's midnight for me. After the release I'm going to sleep
@MᴀʀsUʟᴛᴏʀ what would you like me to refer to you by on the Cheddar release? "somebody", "Mars", maybe your real name?
 
Okay, @Quill registers on a service where you can make stickers, @Upgoat makes the design, and... Erm...
 
@Quill design is the cheddar org logo, lets make these stickers a reality
 
7:23 AM
@Upgoat @somebody1234.
 
Siri on Mac doesn't want me to know how to juic an avocad
 
@Quill ._.
 
Greetings golfers!
 
@Quill Ask Google on Android.
 
I am excited to announce, after four hard months, Cheddar, the programming language, is released!

7:30 AM
OK Google, how to juice an avocado?
 
@Upgoat maybe I ought to make a cool program in Cheddar
 
G'night all!
 
night
 
@Katenkyo Greetings part of golfers!
 
@Upgoat I wonder if it will be better than at golfing than java ^^
 
@Katenkyo It should be as golfy, and maybe even golfier, than JS.
 
Siri for Mac: imgur.com/F5V9EWC
 
@zʏᴀʙiɴ101 I might give it a try so ^^
 
7:57 AM
A very small list of cheeses that @Upgoat can use for code names:
Cheddar
Mozzarella
Provolone
Edam
Gouda
Colby
Feta
Emmental
Zigerbrüt
Saganaki
Add Red Leicester to the list.
I should make a census of PPCG users.
Here is a census map with approximate locations of PPCG users. Ping @zyabin101 to add yours.
I only need the country and region/state/province/territory of a user to be added.
 
8:17 AM
use SEDE
SELECT Location FROM Users WHERE Location IS NOT NULL
 
I'd better go with scraping the Users page into my mind, then writing the location data into the map.
 
@Upgoat "1.0-alpha" isn't a valid version in node -_-
 
@Optimizer why 13187 ?
 
8:35 AM
@LeakyNun I do believe MultiplicativeOrder is a valid answer for that in Mathematica

8:52 AM
@EʀɪᴋᴛʜᴇGᴏʟғᴇʀ Hey Erik, was just thing about your program flags meta post - how would you count flags that don't start with a hyphen? eg interpreter program n where the n turns on numeric output.
*thinking
 
@Sp3000 This is what I call "extra arguments". Note that the filename, or an option accepting the code are not considered "extra", but in execute program lazy, lazy is an extra argument, so +4 bytes. So the n there is +1 byte. The space is required; it does not count.
 
So... extra arguments are more than just filenames?
 
With Mathematica, does anyone know if a false rule can be used for pattern condition /;?
 
9:08 AM
It should be the standard for publishing programs with unprintable characters on PPCG.
Situation: there are 16 competing standards.
 
@MartinEnder x_ ±y_:=BitOr[x,x+1]±BitAnd[y,y-1]/;x<y for 39 bytes, but it terminates with the correct values except that the operator is present and unevaluated. A fix could be x_ ±y_:={x,y};x_ ±y_:=BitOr[x,x+1]±BitAnd[y,y-1]/;x<y but increases it to 53 bytes. Probably a dead end?
 
@miles I tried this as well. You can save one byte with x_ ±y_={x,y}, but I'm not seeing anything else.
 
@MartinEnder ah well, it was promising. Maybe a future challenge could bring those operators into play.
 
@miles well, codegolf.stackexchange.com/questions/82867/… ... and I'm sure there's quite a few older challenges where I could have used that.
 
Oh you found a use already! I'm agree that among all the previous challenges some could probably be shortened with that too
 
9:18 AM
@flawr see that image again
 
@miles while writing that I found an interesting precedence quirk: a~b~c~d~e is d[b[a,c],e] (this part I knew), but a~b~+c~d~e is b[a,d[c,e]]. I can't imagine a situation where that saves bytes (because +c~d~e is the same length as d[c,e]), but I thought it's interesting ^^
 
9:45 AM
@Optimizer Oh right, and +1 cause it's prime!

georgeMy friend made a lisp translator the other day, that is to say it took a string and converted s=>th and S=>Th. It was quite long and I thought that it could be golfed.

However, if the given string is google (lowercase), it will cause an error. For exam...

 
@Upgoat your range operator is broken, and String::(2:4) crashes the prog

I find these in the Code Golf newsletter almost every week.
 
I think that question already has enough answers tbh
(Not that new answers aren't welcome, I just mean there's no real need for me to add one :P)
 
There's really no need to. If you want, answer. If you don't want, don't.
Also, can I create chat rooms in the "Stack Exchange Network" namespace?
(assuming I do have 100 rep on The Stack Exchange Network, which I do)
:(
 
11:16 AM
yes you can
if you want to make a room, go for it
 
Good!
 
I have a good idea for a challenge. :3
Output a snes9x movie file that beats Iggy Koopa when played back on a Super Mario World (U) [!].smc ROM.
 
11:35 AM
@Lynn So basically, a TAS to Iggy Koopa.
 
It's not a TAS because you want the most compressible output, not the shortest.
 
Well, it wouldn’t really be speed-optimized—yeah.
 
I've done one automatic game-playing golf on here for QWOP.
I like these but people complained about that one since OP gave no guidance on how to send inputs to a Flash application.
 
@Lynn No, it should be a coding challenge of how far your bot can get
 
Actually I don't think it was a golf... not sure what the winning criteiron was.
 
11:40 AM
I had an idea for a kolmogorov challenge, where you need to output in wich countries is currently morning (from 5AM to 10PM)
 
10PM is morning?
 
I wanted to write AM
 
also, how is that kolmogorov? the output is time-dependent
after we clarify all that, we move on to the big flame war about what counts as a country :p
 
Because you need output a long list of countries
I'd provide a list
 
kolmogorov is supposed to have fixed output
 
11:44 AM
Ohh, .-.
Then a simple code-golf
 
Challenge idea: generate a roguelike dungeon.
 
ah, and then there's the problem of DST
 
@zʏᴀʙiɴ101 Have you tried generating one? It's hard and requires multiple algorithms, one of wich is a maze algorithm
 
@zʏᴀʙiɴ101 you mean like this?
 
@aditsu DST?
 
11:46 AM
@aditsu Nope.
 
@Bálint Daylight Screwing Time
 
@aditsu Those would be clarified in the actual post
Maze algorithm
Minimum spanning tree algorithm
Flood fill optionally
(BTW, I can go at it, I implemented them before)
 
You don't need mazes.
 
what about dragons?
 
Dragons are excluded from the challenge.
You only have to do the dungeon itself.
 
11:58 AM
if you have dungeons, you need dragons :p
 
I am going to spam the Sandbox with the explanation of every step in running the dungeon digger algorithm.

@zʏᴀʙiɴ101 It's kind of hard to determine, whether a maze is legal or not

Dungeon generation from my golfy roguelike.
 
@Lynn Will it have public servers?
 
12:11 PM
I doubt it
X=?#;S=' ';W=80;T=3e3;R=->a,b{a.+rand b}

    l=X*T;$s=S*T;x=0
    t=(s=0..6).map{|x|R[9,9]+9*x+W*R[4,15]}
    t.map{|a|b=t[x+=1]
    s.map{|x|s.map{|y|l[a+x+y*W-243]=?.}}
    [W,1].map{|x|l[a+=x*(b<=>a)]=?.until(b||a)/x==a/x}}

puts l
That's the dungeon generation code.
 
Ruby?
 
The indented bit does the actual work. Everything above is setup, and the line below prints the result
Yeah
 
@Bálint This was a pretty cool read.
 
It plots out some square rooms and connects their centres with L-shaped corridors
The full code so far is pretty funky
It has dungeon generation, movement, monsters, line-of-sight, combat, and death. The dungeon is infinitely deep! It’s not fun, though, at the moment.
 
@Lynn Can I re-make the code into Python?
 
12:16 PM
Sure! As long as you don’t, like, release it without crediting me, I guess ^^
 
What the display size should be?
 
@Lynn You could add randomly additional corridors, so the dungeon doesn't get too linear
This is the best dungeon generator I could find
Uses the same technique I described above

@LegionMammal978 I can think of way too many file formats to count.
 
@DrGreenEggsandIronMan Then list some ;)
 
This is a list of file formats used by computers, organized by type. Filename extensions are usually noted in parentheses if they differ from the format name or abbreviation. Many operating systems do not limit filenames to a single extension shorter than 4 characters, as was common with some operating systems that supported the FAT file system. Examples of operating systems that do not impose this limit include Unix-like systems. Also, Microsoft Windows NT, 95, 98, and Me do not have a three character limit on extensions for 32-bit or 64-bit applications on file systems other than pre-Windows...
more file formats than you will ever want
 
Good idea

That doesn't mean the design of the FAT directory table made sense
 
@Doorknob echo is not a format I know. {a..z}{a..z}{a..z} is not a format I know.
 
@quartata It was a pretty reasonable compromise. Given only 32 bytes per entry to work with, it packs in an astounding amount of information.

Anyway, I've got a little puzzle/challenge. The motivation is that I had the idea of making an FPS game where the room layout is non-Euclidean, perhaps toroidal.

What is the smallest and/or simplest room layout that fulfills these criteria?
