Q: Tips for golfing in Ruby

What general tips do you have for golfing in Ruby? I'm looking for ideas that can be applied to code golf problems in general that are at least somewhat specific to Ruby (e.g. "remove comments" is not an answer). Please post one tip per answer. -- borrowed from marcog's idea ;)

O_o Ruby's syntax is almost as... odd... as Pythons...

c=->n{/(\d)\1/=~n.to_s}

wat.

In Cheddar, how should tokens be associated with their classes?

quartata

10:04 PM

@Downgoat What's wrong with that?

Seems fairly straightforward

Downgoat

._. not really. It looks like perl

quartata

->n{ } is a lambda

/(\d)\1/ is a regex

=~ applies the regex

Downgoat

@quartata okay, nvm that's kinda like Cheddar's syntax then

quartata

n.to_s takes n and converts it to a string

Q: Top 10 editors partitioned by year

I wanted to get some stats on who has done the most edits on Code Review, so I wrote the following query on SE Data Explorer. All improvement suggestions are welcome. Note that I used a cursor to partition top users by year because at first there was a fundamental flaw in my logic trying to get...

CR is still good.

@QPaysTaxes good for you

Q: Triangular wave

The Challenge In this challenge I want to propose to calculate an array of coefficients of a triangle wave. The triangular wave should have a period of 2pi and an amplitude of 2, from -1 to 1 Winner To win this challenge you have to write the highest performing code

@QPaysTaxes what?

Downgoat

10:07 PM

Cheddar's source code isn't golfed though

just the tokenizer is 37KB

@QPaysTaxes I am sorry about that.

Quill

@QPaysTaxes I can't keep up with this room, like ever

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@QPaysTaxes what does this do?

Downgoat

I should setup a basic Cheddar REPL now that expressions are actually working!

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@Downgoat yes pls

wuold help but can't really right now Q_Q

bai to go get work done.

Downgoat

10:14 PM

bai!

Phrancis

It's kinda sad you can't really golf in Java... by the time you're written public static void main(String[] args){} you probably already lost to most people

Downgoat

@Phrancis you can post a function

^^ right

nodejs docs are so helpful...

they are the worst...

Does anyone know nodejs?

Quill

10:19 PM

npm are giving away socks for PRs on their docs

Downgoat

@Quill makes sense because they suck so much.

Quill

@Downgoat for some values of know

Downgoat

but goats don't wear socks...

Quill

they have little wombats on them

Downgoat

@Quill how tak stdin, i tri for thiree minut and no input ;-;

Quill

10:20 PM

there's a prompt package on npm, but I don't think that counts

  process.stdin.resume();
  process.stdin.setEncoding('utf8');
  var util = require('util');

  process.stdin.on('data', function (text) {
    console.log('received data:', util.inspect(text));
    if (text === 'quit\n') {
      done();
    }
  });

  function done() {
    console.log('Now that process.stdin is paused, there is nothing more to do.');
    process.exit();
  }

Downgoat

tank you

@Quill so how would I write a repl?

Dennis

@Downgoat This should work.

quartata

There's a readline package also

Quill

@Downgoat If I knew that, I wouldn't have a certain issue still open on my chat terminal repo

Downgoat

10:22 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ ^^^^

quartata

But I agree it's dumb that you have to have a package just to do it

Downgoat

@Dennis wow. nice.

@quartata it's dumb because it's JavaScript

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat :(

quartata

ah right

But see Node.JS is a special kind of dumb

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I'm going to wallow in my former victory :P

Downgoat

10:23 PM

yes

but it also a special kind of beautiful

Dennis

@Downgoat Probably suboptimal.

quartata

@Downgoat uh no event loops are ugly

Downgoat

look at that es6. it's beautiful

@quartata event lops?

quartata

@Downgoat The reason why people like node.js

the .on thing

Downgoat

10:25 PM

you mean all the lambdas?

quartata

No

The .on

Quill

@Downgoat are you having a conversation with yourself in code comments?

quartata

@Quill I think he's having a conversation with @MarsUltor

Downgoat

@Quill No, it is with @MarsUltor because for some reason we aren't using chat

Downgoat

if I put one ~~finger~~ hoof on the + wire coming out of a battery and another hoof on the -. Will it electrocute me?

Quill

maybe if you're sitting in the bath

Maltysen

@Downgoat probably not

Downgoat

10:31 PM

okay, just making sure

Maltysen

depends on how conductive goats are

Downgoat

~~( ͡° ͜ʖ ͡°)~~ oh okay

Cᴏɴᴏʀ O'Bʀɪᴇɴ

MARKER ON YOU FACE

so apparently, no studies have been done on the conductivity of goats, but tons have on the conductivity of goat milk

the electricity has to go all the way through your body to your other dfinger

Quill

@QPaysTaxes my sed skills aren't that great

Downgoat

@Maltysen I don't think hooves are very conductive though

Zach Gates

@QPaysTaxes Just in general

Downgoat

@Quill how did you get user input in your caht node thing. I need to do it for Cheddar's REPL

oh wait.. you already said you don't know how...

nevermind

Quill

10:38 PM

I have user input, but it works once

Downgoat

tell me how you did it

Quill

@QPays node.js

because the prompt thing isn't async, I can't fetch a prompt after the prompt is done

the terminal thing has so many issues caused by the technical stack. I should just ditch node for Python

Downgoat

Someone give me a whale so I can slap whoever designed node.js's I/O with it

Dennis

@Downgoat Pyth takes the cake.

Quill

@QPaysTaxes Yeah, that's the prompt plugin I use

@Downgoat it's not necessarily Node's IO, JavaScript isn't async, like most standard I/O systems are

Downgoat

10:41 PM

@Dennis ._______. how... @CᴏɴᴏʀO'Bʀɪᴇɴ @Maltysen ^^^^

Quill

that said, a prompt plugin that keeps going would be nice

Cᴏɴᴏʀ O'Bʀɪᴇɴ

FML

FML FML FML AHHHHHHHHHHH

Downgoat

Node.js: where taking input is harder than making a programming language

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Yes.

Downgoat

@QPaysTaxes yes

Cᴏɴᴏʀ O'Bʀɪᴇɴ

there

Dennis

@Downgoat Every number with digit sum 6 is also divisible by 3 and therefore not prime. That means the only conditions we have to check is the digit sum and that the last digit is 1.
