dear diary,

today I bent the rules a bit

A: Paint Starry Night, objectively, in 1kB of code

ImageMagick, 4816.84 Uses the ImageMagick 'programming' language, using the following options: convert i -resize 386x320! o.png Assuming the following 945 byte source file (given as hexdump): 00000000: 89 50 4E 47 0D 0A 1A 0A - 00 00 00 0D 49 48 44 52 | PNG IHDR| 00000010: 00 00 00 30...

Doorknob

@orlp you can just call that Bash

orlp

@quartata why did you edit the ; to a :?

RikerW

rofl

quartata

9:03 PM

@orlp I assumed it was supposed to be a colon.

orlp

the ; was generated by my hexdump program

zyabin101

No, our policies disallow external libraries that are disallowed. Is IM allowed?

Doorknob

@quartata did you think he manually typed out the entire hexdump?

quartata

@zyabin101 It's fine.

orlp

@zyabin101 it's not a library

@Doorknob imagemagick is the interpreter

quartata

9:03 PM

@Doorknob yes

This is a constant output challenge so non-programming languages are legal

RikerW

@Doorknob What should I have done????

Doorknob

@orlp Right, but that code runs on bash too, doesn't it?

RikerW

Really, what? For future reference.

Doorknob

well I guess you'd have to escape the !

@RikerW nethackwiki.com/wiki/Wish

orlp

@quartata with your change the hex2bin program chokes

the last one really needs to be ;

either way, even if you count command line parameters as part of the byte limitation, my answer still fits in 1kb

quartata

9:05 PM

@orlp ...sorry

I changed it back already

orlp

now the real question becomes.. how did I generate that original 945 byte source file? ;)

@Doorknob how did you get the gif of the trout slap image?

@CᴏɴᴏʀO'Bʀɪᴇɴ you have to install pillow, a safer fork of PIL.

How do I do that?

In a console

@CᴏɴᴏʀO'Bʀɪᴇɴ Sorry not sorry?

On Windows I had trouble installing the python requirements. A safer option is to use pillow (pip unistall PIL, then pip install pillow) and change the first line to from PIL import Image. — mınxomaτ 5 hours ago

Just put the Scripts directory in your PATH.

He's pretty much lost to CR, clearly.

That reminds me I need to go into the Nth Monitor and lure Quill back to us

I can understand that.

quartata

@Mast OH... hi. Er... just a little joke see

Heh

Mast

As for Quill, his code improved quite a bit. Not sure you want him back ^^

feersum

@FlagAsSpam ? Did so.

quartata

@Mast We do. And we want Hosch back too.

We almost had them 100% over Christmas

We mean what makes something a programming language.

Not something you usually run into on CR.

FlagAsSpam

See: HQ9

quartata

@Dennis Could you add the "no-eval" version of Rotor to TIO?

It should be safe.

even though it is much more useless

FlagAsSpam

Is eval ever not safe in JS?

quartata

@FlagAsSpam This is Groovy though.

I use eval to eval the input which is bad.

FlagAsSpam

@quartata Oh.

orlp

9:52 PM

@quartata and others who might be interested, I added an explanation of how I generated the input file

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@FlagAsSpam It depends on the context. I use eval for the main part in Jolf.

FlagAsSpam

@CᴏɴᴏʀO'Bʀɪᴇɴ Safe as in file I/O, shell, and network access is denied.

Cᴏɴᴏʀ O'Bʀɪᴇɴ
