@Cyoce does it explode in like a fire or just like goop?

Cyoce

Pretzel is prefix. It has implicit input, and can be done tacitly.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Sorry, I'm an idiot

Sp3000

@xnor Hmm the first part makes sense at least, dunno about the second

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I thought "o hey math it must be infix"

Cyoce

5:01 AM

If a definition for a function is not complete, e.g. *3 (because * takes two arguments), that missing value will be taken as an argument to the function.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

ocool

now I g2g

Cyoce

Again? lol

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ bai

are you actually going this time?

Cyoce

@CᴏɴᴏʀO'Bʀɪᴇɴ bye ಥ_ಥ

@Downgoat It depends on the complexity of the program.

Downgoat

@Cyoce please make ಠ_ಠ do something cool in pretzel

Cyoce

5:03 AM

@Downgoat Good point.

ANNOUNCEMENT: Taking ideas for what ಠ should do in Pretzel.

Alex A.

hack teh mainframe

Downgoat

It should also have behavior in cheddar...

Quill

@Cyoce Do a Google Forms thing ;)

Downgoat

ANNOUNCEMENT: What should ಠ_ಠ be preinitialized to in Cheddar?

Alex A.

Not if Cheddar is intended not to be an esolang

Q: Default acceptable image I/O methods for image-processing challenges

I do not feel that the default general acceptable I/O methods sufficiently cover image-processing challenges. So I would like to poll. What are the default acceptable I/O methods specifically for image-processing challenges? Please post each I/O method, one per answer.

Downgoat

@AlexA. ಠ_ಠ is a valid variable name in cheddar

Quill

@Downgoat that's why there's a ;) in there

Alex A.

5:05 AM

That's different from having it preinitialized to something

It's a valid variable name in any number of languages that support Unicode input

Dr Green Eggs and Ham DJ

Is having the user type a number an acceptable IO method? e.g. in vim <user number>@q to run a macro a variable number of times?

And would that count as 3 or 2?

Downgoat

@AlexA. alex is preinitialized to false so I don't see why I can't make ಠ_ಠ preinitialized to something

4

Alex A.

You can do whatever you want, I'm just recommending against it

Dr Green Eggs and Ham DJ

Is "alex" really preinitialized to "false"?

Downgoat

@DrGreenEggsandHamDJ yes

it is in the documentation itself

docs.cheddar.vihan.org/booll.html github.com/cheddar-lang/Cheddar/blob/master/src/interpreter/…

Quill

5:11 AM

Good to see you finished your documentation

Downgoat

@Quill I still need to write about classes and all but yeah, I've finished docs on the primitives

Cyoce

247 chars! so close!

Downgoat

@QPaysTaxes maybe later

Cyoce

@QPaysTaxes Shit I forgot to add regex to pretzel

Downgoat

I'm trying to get the language working as quickly as possible, then add everything

@Cyoce Are we posting messages in bold now

Alex A.

5:14 AM

Please no

Why do you have 3 separate styles of comments?

Cyoce

@Downgoat Are we posing questions as statements now

Alex A.

Supporting both # and // seems odd IMO

Downgoat

@Cyoce I don't know, are we

Dr Green Eggs and Ham DJ

What do you get when you cross a rhetorical question and a joke?

Alex A.

My life

Downgoat

5:15 AM

@AlexA. I added # because some people like swiss cheese

Alex A.

That... doesn't really answer my question

Quill

@DrGreenEggsandHamDJ A bad sense of humour and probably a good reason to stop telling jokes

Downgoat

undefined value in Cheesecloth is going to be _UNK for now...

Dr Green Eggs and Ham DJ

@Quill Oh, I already have a bad sense of humor.

I love it.

Downgoat

@Quill if I have a file with lots of imports, will I have to post all the files to code review?

Dr Green Eggs and Ham DJ

5:17 AM

@Downgoat Yes.

Alex A.

I'm proud to have made my contribution to Cheddar by initially proposing the name. (As a joke, FWIW.)

Quill

@Downgoat depends how important those imports are

Dr Green Eggs and Ham DJ

Cyoce

Downgoat

@AlexA. look at me, so young and full of energy. Then I decided to make a language...

Alex A.

5:18 AM

hahaha

Cyoce

Why is "define primitive classes" checked if the primitive classes are not all defined?

Downgoat

the above is my motto

Quill

Array isn't a primitive in JS btw, it's a literal, but not a primitive

He's done the primitive value types, at least

Downgoat

@Quill but they are in Cheddar

Quill

@Downgoat do you have a function or keyword to test inheritance

Downgoat

5:20 AM

@Quill yeah

t_repl

Quill

> In JS

Downgoat

see the cheddar docs

@Quill did I state they are primitives in JS?

Quill

@Downgoat it was a btw

Downgoat

@Quill btw, Pygmy goats are the best type of goats, not boer

Cyoce

Question about cheddar syntax: why -> (a,b) a+b and not (a,b) -> a+b ?

Downgoat

5:23 AM

@Cyoce so you can do avocad -> (juicr, thirtee_minut) juicr(thritee_minut)

which assigns avocad to the functino

Cyoce

@Downgoat Am I missing something? What's wrong with avocad (juicr, thirtee_minut) -> juicr(thritee_minut) ?

Downgoat

@Cyoce that would multiple avocad by (juicr, thritee_minut) -> juicr(thritee_minut)

but if it's that bad I can change it

ok

is this synatx also weird:

Cyoce

@QPaysTaxes Wait... shouldn't that apply the expression to avocad?

@Sp3000 For the most part. Some fail because multiplication isn't commutative with matrices.

Downgoat

strawpoll.me/10116405

@Cyoce D: why the chars with accents

Cyoce

@Downgoat They perform different operations on the variables.

Sp3000

5:30 AM

@Mego I'm asking because I'm not sure it'd be useful to output all three values if some identities still hold, since it might be easier to derive the other two from the first

(but I haven't checked whether that's possible)

Downgoat

:/ I think you should pick more dedicated symbols. I tried with TeaScript and all these accents and foreign chars really make you're code ugly

Quill

@Downgoat that didn't answer my question

and neither did the docs

I asked whether you can tell if Dog is inheriting Animal, not how to start the REPL

Downgoat

5:32 AM

@Quill yes

Cyoce

@Downgoat ^^^^^ is why I have accents.

Downgoat

Checking instance: Dog is Animal Checking inheritance: Dog inherits Animal

haven't done classes yet so it's not implemetned though

Quill

Does/will that work on builtin types?

Avodad inherits Object

Downgoat

there is no global Object

but yeah

MySpecialNumber inherits Number

Anonymous

@Sp3000 For example, sin(A+B) = sin(A)cos(B) + cos(A)sin(B) holds, but you can't commute the sines and cosines.

Cyoce

5:35 AM

@Downgoat inherits vs extends? (what's the difference)

Quill

@Cyoce inherits is the testing operator, extends is the operator you use during the defining of the type

orlp

@Mego what do you mean with commute?

Quill

@Downgoat so there's no global object type?

Cyoce

@Downgoat couldn't you make it context-sensitive? I.e. defines if in a class declaration, tests if in an expression?

Quill

@Cyoce potentially, yeah, I'm not the language designer, ask Downgoat

Anonymous

5:36 AM

@QPaysTaxes Correct

Anonymous

Because matrix multiplication isn't commutative, the identities fail if you commute multiplications

Ashwin Gupta

Yes! I got the alien shooting working. (The offset is intentional, so its not insanely accurate). Next up, collision detect w/ missiles and orientation of missiles. niwhsa9.github.io/Space-War

Anonymous

2*sin(A) = 2*cos(A)*sin(A), but 2*sin(A) != 2*sin(A)*cos(A)

Downgoat

@Cyoce yeah, good idea. Will do

Quill

@QPaysTaxes oh hey I recognise that

Cyoce

5:38 AM

@Downgoat :D

Ashwin Gupta

browser....

we talked about this remember.

its either chrome or FF...

or it wont work.

Downgoat

@AshwinGupta for collision detection I recommend this library: github.com/jriecken/sat-js making a SAT implementation by yourself is not so fun.

Ashwin Gupta

@Downgoat hey thanks, that will save me some time.

Downgoat

@AshwinGupta Works in Safari for me

Ashwin Gupta

@QPaysTaxes ? weird. Old version maybe?

@Downgoat cool, I can add that to my list of working browsers.

Anonymous

5:40 AM

Huh, apparently the double-angle formula for sine doesn't hold with matrices... Either that, or inaccuracies are cropping up.

Ashwin Gupta

@Downgoat I actually sorta wrote a collision detect thing earlier for something else: (named after java intersects)
 this.intersects = function (x, y, w, h) {
        var flag = true;
        if (!(y >= this.y - 25 && y <= this.y + 25)) flag = false;
        if (!(x >= this.x - 25 && x/*typo, y*/ <= this.x + 25)) flag = false; //Caught ya!
        return flag;
    }

Downgoat

@AshwinGupta that'll work for rectangles, not so good with more complex shapes

Ashwin Gupta

true, I'm just using rectangles though lol cuz Idk how to do hard shapes

Downgoat

Also, I finished Level 2 and no more aliens are coming, is that supposed to happen?

Ashwin Gupta

yup

sorry I've only got configs for levels 1 and 2 setup.

normally I'd say the arrow functions. But...

downgoat fixed that for me.

so I have no idea.

Downgoat

5:43 AM

@QPaysTaxes you must be running an ancient version of firefox and refusing to update

Ashwin Gupta

wait, downgoat u got ff? Can U try?

Downgoat

Safari never works for anything and it works for me

Ashwin Gupta

lul^

Downgoat

Images/sounds don't work for me in firefox

Ashwin Gupta

ah shit.

Downgoat

5:44 AM

@QPaysTaxes that means the URLs are borked or it's https error

Ashwin Gupta

it works in my FF....

OHHH

ok, well this is weird. When I run locally (not through github pages but through my file system) it works on FF. When I go to my github IO link, it doesn't work.

why might that be.

@QPaysTaxes nope versions are current.

Downgoat

^

Cyoce

@Downgoat if true foo(). How do you know where true ends and foo() begins? I.e. in this if syntax, how does/will the parser determine which is the condition and which is the body?

Ashwin Gupta

yeah

Downgoat

@Cyoce magic

it just works

Ashwin Gupta

5:46 AM

only 11 here but ya know

bye

ill figure it out tmrrw

Cyoce

@Downgoat I shall break it.

Downgoat

bai all

Cyoce

bai

@Cyoce pls no sabatog pull request

@Downgoat no. I will find code that it doesn't work for.
