what does Python do if you add two things that can't be added together?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

errors

Downgoat

ok, that is what Cheddar's behavior will be then

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Python 3.4.2 (v3.4.2:ab2c023a9432, Oct  6 2014, 22:15:05) [MSC v.1600 32 bit (In
tel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

Downgoat

what should Cheddar's behavior be for int+string?

Zach Gates

Check if the string is an int

quartata

12:34 AM

int.toString() + string

Zach Gates

add them as ints if it is (or a float)

Cᴏɴᴏʀ O'Bʀɪᴇɴ

^^

Downgoat

should it do String:int + string?

ok

writing the interpreter is waay more fun then writing the parser...

Zach Gates

true

quartata

Coercing to int is nice on paper but it could result in nasty things in practice

Cᴏɴᴏʀ O'Bʀɪᴇɴ

12:35 AM

I like writing a parser

quartata

If you do do it like that do it like Perl: + is add and . is concat

Cᴏɴᴏʀ O'Bʀɪᴇɴ

except for the edge cases

quartata

+ always tries to coerce to int

. always coerces to string

Quill

@Downgoat, for primitives you should try and do it like javascript, but for types that inherit Object, throw an error IMO

Downgoat

@Quill NO

quartata

12:35 AM

@Quill oh no no no

Quill

and why is that

Downgoat

JavaScript has the stupidest type casting system

quartata

please no

Downgoat

[] + [] should NOT be ""

Quill

Array isn't a primitive....

Cᴏɴᴏʀ O'Bʀɪᴇɴ

12:36 AM

That's true, but helpful for JSFuck

Downgoat

@Quill it is (in Cheddar)

quartata

[] + ![] = false

JS everybody

Also @Downgoat please PLEASE make integers and floats separate types

Downgoat

{} + {} = NaN

@quartata why?

quartata

@Downgoat oh my

Quill

console.log([] == "") //true
console.log(![] == !"") //false

Cᴏɴᴏʀ O'Bʀɪᴇɴ

12:38 AM

Because [] is truthy.

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ that is dumb. [] should be falsey

Quill

@QPaysTaxes that's a chrome and V8 thing, not JavaScript spec

quartata

10000000000000000 == 9999999999999999
true

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat ik

@quartata That's just number types, not just javascript

RenderSettings

@quartata no, make the default int type bignums

bignums are fucking magic

Cᴏɴᴏʀ O'Bʀɪᴇɴ

12:39 AM

^

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ That's why integers should be separate from floats

Downgoat

@quartata Cheddar will use my ulta-fast BigInt library for large numbers

quartata

Floats lose precision like that

@Downgoat Has nothing to do with the size.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata idc

quartata

It's because all numbers are floats in JS

They lose precision which causes dumb shit like that

Downgoat

12:39 AM

bigint = infinite prescision

quartata

If they were longs or something that wouldn't happen.

RenderSettings

I mean, it would happen, just at a very high number instead

quartata

Please PLEASE do NOT make integers and floats one type

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@ZachGates check your skype account.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata shut up already >_>

RenderSettings

12:40 AM

Oh, long int instead of long float

quartata

@RenderSettings Yeah.

Downgoat

@quartata bignum = infinite prescision

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ You understand why that's a problem right?

Downgoat

there is no need to sepearate them

Eᴀsᴛᴇʀʟʏ Iʀᴋ

> infinite

Dennis

12:40 AM

Found a better method and fixed a bug in #

RenderSettings

bignum = black magic

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@Downgoat SPELEING

quartata

@Downgoat Why use a heavy-memory arbitrary precision number when a long can hold both those numbers

RenderSettings

incidentally, Hoon's atoms are bignums and it's glorious

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata I really don't care honestly. it doesn't affect my coding, so I don't care. If it were to, then I'd just use a different tool.

Downgoat

12:41 AM

@QPaysTaxes ints will convert to bigints once a certain limit has been exceeded

RenderSettings

>heavy-memory
bro do you even gmp

quartata

@RenderSettings Yes I do

Still no point in using one when a long is fine

Dennis

@quartata Not false, "false".

Cᴏɴᴏʀ O'Bʀɪᴇɴ

^

quartata

@Dennis even worse

@QPaysTaxes [] + ![] doesn't produce false it produces the string "false"

Dennis

12:42 AM

> [] + ![]
< "false"

RenderSettings

haha what

Eᴀsᴛᴇʀʟʏ Iʀᴋ

IKR?

Maltysen

@CᴏɴᴏʀO'Bʀɪᴇɴ finished your hw?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

It makes sense if you actually consider JS's arithemtic process.

quartata

![] = 0

[] = ""

Cᴏɴᴏʀ O'Bʀɪᴇɴ

12:42 AM

@Maltysen not even close

@quartata that's not right

Dennis

> {} + {}
< NaN
> ({} + {})
< "[object Object][object Object]"

Eᴀsᴛᴇʀʟʏ Iʀᴋ

[1,2] + [3,4]
"1,23,4"

rofl

RenderSettings

@Dennis ALL OF THESE EXAMPLES ARE PERFECTLY FINE, MOVE ALONG CITIZEN

Maltysen

@Dennis ok, that one I don't get

quartata

I think it's [] + false -> "" + false -> "false"

Cᴏɴᴏʀ O'Bʀɪᴇɴ

12:43 AM

oh, I get it

Quill

I'm planning on writing a blog post that explains that javascript stuff

quartata

It coerces the boolean to a string

@Quill You can't defend this kinda stuff. I'm sorry, it's just wrong.

=== is great though

Maltysen

@quartata so useful though

quartata

Not even Perl does this level of coercion, and Perl freaking STORES numbers as strings

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Quill Please write it at least unbiasedly, I do not want to read another fucking bunch of vapid nonsense

Quill

12:44 AM

@quartata I can and will defend this stuff... and then I will eat a pizza

quartata

@QPaysTaxes Well, it's one of three ways it can store it.

Maltysen

@Quill \o/ js pizza shield

quartata

Depends on the context.

Downgoat

Please recommend Built-ins for Cheddar

Cᴏɴᴏʀ O'Bʀɪᴇɴ

How can you attack JS if you stand behind a shield of perl?

Dennis

12:45 AM

@Maltysen (Forgive my terminology. I have no interest in learning JavaScript properly.) {} is a code block in the first example, but a dictionary in the second.

RenderSettings

That...might be even worst?

quartata

@Maltysen Really? The last thing I want in production code is having to spend 10 minutes figuring out how something gets coerced and having it explode in my face

Quill

@CᴏɴᴏʀO'Bʀɪᴇɴ do you mean that from the perspective of a javascript hater or fanboy

quartata

@Quill fanboy

Maltysen

@quartata i'm not saying its good overall, just that its useful (but IMO tink its is good overall)

Downgoat

12:46 AM

@QPaysTaxes PascalCase for classes. camelCase for methods

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Quill ?

quartata

Although both terms are derogatory IMO please don't use them in any intellectual debate on JS

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@CᴏɴᴏʀO'Bʀɪᴇɴ where did he do that?

ohai @Phrancis

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata There's no such thing. the same shit is thrown around every time

Eᴀsᴛᴇʀʟʏ Iʀᴋ

I saw that.

quartata

12:46 AM

@Maltysen Useful in golfing that's for sure

Maltysen

@Dennis why is it different?

Downgoat

> Everything Jelly has. 'Nuff said.

...

Quill

@CᴏɴᴏʀO'Bʀɪᴇɴ did you mean like "don't be a biased fanboy" or "don't be a biased hater"?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Quill Be unbiased

quartata

Oh shit does that form show my real name on my Google account

Dennis

12:47 AM

@Maltysen Because a code block in parens would be a syntax error, so it's assumed to be a dict.

quartata

@Dennis Code blocks aren't a type; I think that's just what happens when you add dictionaries

Maltysen

@Dennis oh that's wicked cool

Downgoat

> Number, PIZAAA

who is posting these ._.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Not me

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@Downgoat sowee

Maltysen

12:48 AM

@quartata empties eval to undef iirc

Eᴀsᴛᴇʀʟʏ Iʀᴋ

I only did that one.

quartata

@QPaysTaxes Because I have a Google+ account for RL shit

And I was using Chrome on an old computer where I don't have a different Google account as default

Downgoat

@quartata it only stores the timestamp of posting

quartata

@Downgoat OK, thanks.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Can we see results?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

12:49 AM

@quartata are you a criminal or something?

and ^^

quartata

@EᴀsᴛᴇʀʟʏIʀᴋ No...

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Then why are you so afraid?

Just wondering.

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ ^

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Because his name is "Herbert Tata"

Maltysen

@EᴀsᴛᴇʀʟʏIʀᴋ @quartata IF YOU HAVE NOTHING TO HIDE YOU HAVE NOTHING TO BE AFRAID OF

quartata

12:50 AM

Not a fan of having my privacy invaded, that's all

Maltysen

hehe

Quill

mapToFortyTwo haha

@quartata ^

Downgoat

Whoever posted "split to array grid of chars and rows". could you explain what that is supposed to mean?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Quill That was mine :D

@Downgoat That was me

Quill

12:52 AM

@Dennis the second example works fine on chrome
