why would you be pulling from Heroku?

phase

@Downgoat No, Heroku is pulling from GitHub. Except they're not pulling, only cloning the files.

oh no I need a namespace and phase is taken

Downgoat

so why does it matter if .git and/or git data is deleted?

Alex A.

@phase phasesaber?

jadon420?

phase

@Downgoat I need to pull the git submodules because Heroku doesn't pull them with the automatic deploys like it does with the manual pushing.

@AlexA. It's <project>-<namespace>.rhcloud.com, so that'd be o-phasesaber.rhcloud.com, and that's super long.

Alex A.

o-shit.rhcloud.com

phase

12:05 AM

I don't want to do that as I might ant to create other applications on OpenShift in the future, and they'd go under the shit namespace.

Downgoat

@phase oh, ok. Couldn't you store all your submodules in a different folder/file and then have a script to setup git and install submodules?

phase

@Downgoat The folder/file is the git submodule, and the script is git submodule update --init. If Heroku doesn't support it, then I can't use them.

Downgoat

Have the script install git submodule?

phase

@Downgoat It has git on the server, it just doesn't have the git data for my repo. I'd have to clone the repo in a subdirectory, move the git data to the main directory, and then issue the command.

quartata

All right, back

@Downgoat Can I see your code for Cheesecloth? I'm pretty concerned about the potential for a code injection if you're doing anything significant in bash

orlp

12:09 AM

think we should close this

oops

quartata

wrong copy pasta

orlp

oh never mind

Downgoat

@quartata github.com/cheddar-lang/Cheesecloth/tree/master/src

orlp

dennis already closed it

Downgoat

The only bash thing: github.com/cheddar-lang/Cheesecloth/blob/master/src/bin/cpm

orlp

12:10 AM

this guy is a fraud

Nikhil Khurana

1 1

he copy/pastes challenges to outsource the solution to codegolf

quartata

@Downgoat Oh, all right. That's fine

also you really should use JSON

Downgoat

@quartata json won't work very well

json sucks

quartata

Why? JS has built in support for it

phase

TOML please

Downgoat

@quartata that is not a good reason to use JSON...

phase

12:13 AM

JS has support for everything since that's the only thing people code in.

Alex A.

@orlp We deleted both

Downgoat

JS has a built-in for shitty type casting, that doesn't mean it's good

quartata

@Downgoat In this case it is.

Who gives a shit about what the config format looks like as long as it's easy to use

Alex A.

@QPaysTaxes They were in the comments

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata we're using INI because I spent time to make it O^O

quartata

12:14 AM

FWIW INI is fugly

@CᴏɴᴏʀO'Bʀɪᴇɴ ok but still

Cᴏɴᴏʀ O'Bʀɪᴇɴ

no

Alex A.

Feature request: Get some PPCG rep :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

^

v

Alex A.

Maximum length of a sequence; Rearrange letters of string

Those are the SPOJ links

Cᴏɴᴏʀ O'Bʀɪᴇɴ

the second one is trivial sorting by char codes and checking for equality :P

Downgoat

12:17 AM

@quartata ಠ_ಠ

ini is beautiful

JSON is ugly af

quartata

@Downgoat Uh, it's true?

@Downgoat Dude, you know JSON is literally what happens when you stringify an object right

Cᴏɴᴏʀ O'Bʀɪᴇɴ

^

Downgoat

@quartata yeah?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

but we're using ini

quartata

@Downgoat So.... you're basically saying that dictionaries in JS are ugly

Downgoat

12:18 AM

pretty much

quartata

so you're admitting that JS is trash

which means I win

Downgoat

no?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

they're worse in python

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ they're exactly the same in Python

Cᴏɴᴏʀ O'Bʀɪᴇɴ

and I love js dictionaries

@quartata nope.

Downgoat

12:19 AM

Saying the object literal syntax in JS (which you should almost never use) does not mean JS is bad.

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ Uhh?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

"asdf": prop versus asdf: prop

Downgoat

You should be using Map for dictionaries anyway

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ Oh, ffs.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata what? something wrong?

quartata

12:19 AM

@CᴏɴᴏʀO'Bʀɪᴇɴ basically same difference

Downgoat

does anynone here know SVN?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

but it's much less convenient

Alex A.

@Downgoat quartata does

Downgoat

@quartata halp with SVN pls

quartata

ok what do you need help with

Alex A.

12:20 AM

svn

Downgoat

so I have some git stuff I need to download

quartata

ok

Downgoat

so right now I am doing:

svn export path/to/file

how would I download that to a specific file?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Kevin Lau - not Kenny

826 8

haha he changed his name

quartata

@Downgoat what do you mean?

Downgoat

12:22 AM

I want to download and rename basically

quartata

svn export takes a remote or local repo and basically puts all the files in it in a new directory

So you do svn export repo new-path

Downgoat

oh

so like git

Cᴏɴᴏʀ O'Bʀɪᴇɴ

git svn

Cyoce

I'm bored. have a few more example programs. feel free to question/criticize as this is a work in progress

∇/∩∂         gcd (takes array)

÷-^φa^⁻Φa√5  golden ratio fibonacci

?<a2a+fàfà   recursive fibonacci

:„1+         recurrence relation fibonacci

∏            factorial, because array(n) = [1..n]

Alex A.

What is

Cᴏɴᴏʀ O'Bʀɪᴇɴ

12:28 AM

@QPaysTaxes he's using the golden ratio to calculate the fibonacci

@Cyoce I really like this language

Alex A.

What is the language

Cyoce

@CᴏɴᴏʀO'Bʀɪᴇɴ thanks! :D

Downgoat

@Quill do you know node? If you do can you help me with it :3

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@AlexA. pretzel

@Cyoce no problem

Cyoce

@AlexA. pretzel, my prefix golfing language.

Alex A.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Quill has been summoned

Quill

Strange, I thought I was still in this room...

Monring

@Downgoat maybe enough to help you out, what's up?

Downgoat

@Quill ok, so I am trying to run some commands in node

Cyoce

Fun fact: the : in the recurrence relation fibonacci :„1+ means subscript, so just „1+ will create an infinite fibonacci sequence generator object (which will infinitely print the next term if this is the last expression in the main function)

Downgoat

I need to get STDOUT which will be a file, it might be big but it's not really a file

Cᴏɴᴏʀ O'Bʀɪᴇɴ

12:31 AM

@Cyoce whoa

Cyoce

@CᴏɴᴏʀO'Bʀɪᴇɴ lazy evaluation FTW

Downgoat

how should I do htis?

Luis Mendo

@DJMcMayhem Sorry about that. Feel free to ask me. The documentation is admittedly a little too long. Knowing some Matlab helps

Quill

Can't you just do a normal terminal stdout to file

Downgoat

@Quill and then read that file?

seems inefficient

Cyoce

12:32 AM

Haskell does the same thing. Open GHCI and type [1..] and it will brutally murder your output stream.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Cyoce you need to make a pretzel-to-(La)TeX converter

Cyoce

@CᴏɴᴏʀO'Bʀɪᴇɴ I don't know (La)TeX, but sure I'll get on that once I make my unicode<->pretzel converters.

Alex A.

Soft pretzels are taste

Cᴏɴᴏʀ O'Bʀɪᴇɴ

:D

quartata

@AlexA. I love soft pretzels

Quill

12:34 AM

Quill$ npm update node -v >> meow.txt
Quill$ cat meow.txt
1.4.28

Can't you just do that @Downgoat

Downgoat

@Quill but my command is already outputting to stdout

@QPaysTaxes what do you mean by that

I need the file in memory

Quill

You're trying to rename/copy a file?

Q: Rainbowlify An Image

code-golf graphical-output image-processing

Quill

that's pretty cool

orlp

@HelkaHomba think you have a mistake

step = cycles / (image width * image height)

Helka Homba

@orlp Where?

orlp

should be

step = cycles / image height

Cyoce

WHAT

TOO MANY BACKSLASHES

orlp

12:51 AM

@HelkaHomba unless you intend for the rainbow to not be in rows

Cyoce

@QPaysTaxes I was testing and it failed

orlp

but that will look weird as cycles increases

Cᴏɴᴏʀ O'Bʀɪᴇɴ

say if two objects have a scale factor of n : m (n < m). Given distance K of the smaller object,what is the distance K' on the larger object?

orlp

@HelkaHomba either way you should add a testcase with a really high cycles, to sniff this out

Helka Homba

@orlp No that's right. The rainbows aren't in rows, it's just tricky to tell

@orlp Good idea

orlp

12:53 AM

also

you didn't specify how you define hue

by what color space

@HelkaHomba ^

Cᴏɴᴏʀ O'Bʀɪᴇɴ

bai again

Helka Homba

@orlp Fixed both issues

quartata

@ArtOfCode Can I just post.title?

Q: Tips for golfing in Swift

What are some tips for code-golfing in Swift? It seems like a difficult language to golf in because of it's focus on safety, but I was wondering if there's any tips to help? Are there any features in Swift that may help it excel in code-golf in certain applications?

tips

Downgoat

@Quill do you know what Error: write EPIPE means?

quartata

oops post.title doesn't work

I'm trying to understand Answer here and my head hurts

i very stupid

Downgoat

haha, svn is so bad it segmentation faults instead of throwing an error

quartata

Ohhh, I get it now

@Downgoat broken pipe

Downgoat

ohh

quartata

1:20 AM

which is a perfectly valid reason for a segfault

Downgoat

duh

Quill

github.com/nodejs/node-v0.x-archive/issues/3211

Downgoat

@quartata no, segfault happens on a different script

quartata

what are you doing to poor svn anyways

Alex A.

Sending it to hell where it belongs

Downgoat

1:22 AM

@quartata there are files on github which I need to download with svn.

Quill

github.com/mhart/epipebomb

quartata

@ArtOfCode I went ahead and deployed the fix for rep notifications that shows the title

Quill

That issue was weird

quartata

now I just need to do comments

Downgoat

@Quill do you know what execFile does?

Quill

1:25 AM

No

quartata

and done

Quill

No: looks like it executed a file

Downgoat

nvm figured it out

DJ McMayhem

@LuisMendo Haha, no problem. I actually learned a fair bit. Although there are still a couple things that aren't clear. I'd love some help on it! I'll ping you about it later.

step = cycles / (image width * image height

@HelkaHomba missing a 360 * there

@CᴏɴᴏʀO'Bʀɪᴇɴ ಠ_ಠ for using var and not let

quartata

1:50 AM

@ArtOfCode debating how to handle IRC logins. The easiest way is to run IRC over ssl and have users message the bot their qpixel logins

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ your INI parser fails for arrays/objects: D:

goat[]=downgoat
goat[]=upgoat

that would output "goat[]": "upgoat" rather than "goat": ["downgoat", "upgoat"]

Geobits

Isn't that what it should do?

Downgoat

@Geobits no, [] denotes an array

[something] denotes an object

Geobits

Yea, but what ugly syntax uses = to add to an array?

Downgoat

@Geobits this is an INI config file, not a fancy programming language

Geobits

1:55 AM

Either way I'd expect to see something sensible. Intuitively, it looks like you're assigning values to a variable (overwriting the first), not adding items to a list.

Downgoat

@Geobits ¯\_(ツ)_/¯ I didn't make INI
