So I just got a newsletter email from an electronics company titled "Iron Man will have nothing on you after you shop here"

Dr Green Eggs and Iron Man

That's a lie! How dare you insult me like that!

He'll still have his breakfast.

Dr Green Eggs and Iron Man

Where do you draw the line with using pictures from google to illustrate your challenge?

flawr

Apollo 11 code now available on Github!

Dr Green Eggs and Iron Man

Is it bad to post a picture from cs.virginia.edu if it perfectly explains what my challenge is about?

Obviously, there is more explanation around the picture.

Anyone have thoughts on that?

Some funny comments in the original Apollo 11 guidance system source code

you've been n inja'd

@Lynn ;-; i forgot random function in cheddar ;-;

should rand(n) return rand(0,n) or rand(1,n)

Dr Green Eggs and Iron Man

Is it 0 or 1 indexed?

Downgoat

what is?

it is [a, b)

Dr Green Eggs and Iron Man

Cheddar (I assume that's what you're talking about)

Downgoat

yeah

cheddar is 0 indexed

Dr Green Eggs and Iron Man

Then it should return [0, n)

Downgoat

10:19 PM

and should it return a floating point or a integer?

Dr Green Eggs and Iron Man

Absolutely an integer.

Downgoat

If they are no arguments it'll return a floating point 0-1 atm

ok

Dr Green Eggs and Iron Man

there should also be rand_float(a, b)

or float->rand(a, b)

or float::rand() or whatev makes the most sense.

Does it have arbitrarily large integers?

Downgoat

It will soon

Dr Green Eggs and Iron Man

Will they be the default?

Rather than a different type.

10:22 PM

@Downgoat There are quite a few good ones=)

Downgoat

@DrGreenEggsandIronMan numbers will implicitly promote to bigints

Dr Green Eggs and Iron Man

That's what python does. :P

Downgoat

yeah ;_;

@Downgoat RT: Is there something real about python that you dislike, or is it just fun to hate?

Just like I like to make fun of JS but don't have any real complaints against it.

Fun fact: Unicode Technical Report #51 officially recognizes ಠ_ಠ as an emoticon.

Downgoat

@DrGreenEggsandIronMan i personally just really dislike python, it's design, and everything else about it.

Dr Green Eggs and Iron Man

Something more concrete though. What about it's design do you mind?

Downgoat

.___. how do i tell if random funciton is working

cheddar> Math.rand(6)
0
cheddar> Math.rand(6)
0
cheddar> Math.rand(6)
0
cheddar> Math.rand(6)
0
cheddar> Math.rand(6)
0

Dr Green Eggs and Iron Man

I'm gonna go out on a limb and say it's not.

LegionMammal978

@Downgoat Relevant XKCD:

RFC 1149.5 specifies 4 as the standard IEEE-vetted random number.

Downgoat

10:27 PM

@DrGreenEggsandIronMan it has no syntax. spaces have semantic value. no actual classes, no notion of this or self or something like that. Programs look like an alphanumeric+underscore mess, devs were too lazy to even make multiline comments. etc, etc.

LegionMammal978

Dr Green Eggs and Iron Man

Are you kidding? Python has classes, self and multiline comments.

Downgoat

@DrGreenEggsandIronMan the fact that taking self as a function argument is hardly native support I'd call it laziness

LegionMammal978

@flawr Busy launching a Saturn V now...

Downgoat

10:28 PM

multiline comments are damn strings

idk what i meant when I said no actual classes

though I bet python is like the most popular language here and i dont wanna start a flamewar >_>

LegionMammal978

I don't really like Python either tbh

Downgoat

:D :D :D +1

Dr Green Eggs and Iron Man

@Downgoat Actually, I'm not sure if that's true. I think python and JS are pretty closely tied.

LegionMammal978

For "professional" things, I use C#

Downgoat

:D i fixed rand!

i was thinking of making an ASCII art builder thing for cheddar but idk if printf counts

LegionMammal978

10:33 PM

@Downgoat What was the problem?

Dr Green Eggs and Iron Man

@LegionMammal978 I did a project in C# recently. I had no experience with it before, but I was blown away by how simple and easy to use it was.

C# is nice. (except for golf)

Downgoat

@DrGreenEggsandIronMan ES6/7 was designed after C# ;)

cheddar> (0:33).map
Syntax Error: Unexpected token at 1:6
1 | (0:33).map

ok thats not good

0/10 JS > C#

Downgoat

Cheddar >= JS > C#

@CᴏɴᴏʀO'Bʀɪᴇɴ question: What are your favorite things about JS?

Mᴀʀs Uʟᴛᴏʀ

I only use C# when I want speed, since it's still pretty easy to modify/decompile a C# program, meaning mot many advantages

when I want speed = almost never

@Downgoat source maps

Downgoat

@MᴀʀsUʟᴛᴏʀ cheddar is also pretty fast

an empty programs only takes .5s to run

;_;

i tried so hard to maek it fast

Mᴀʀs Uʟᴛᴏʀ

@Downgoat Just make a special case for the empty program

Quill

@Downgoat pls make repl be able to time

Downgoat

@MᴀʀsUʟᴛᴏʀ wat shood UI be

Mᴀʀs Uʟᴛᴏʀ

@Downgoat ?

Dr Green Eggs and Iron Man

@Quill Good ~~afternoon~~ morning!

Downgoat

@Quill good aftermorning

oh wait thats not right :P

Mᴀʀs Uʟᴛᴏʀ

10:46 PM

@Downgoat ui for waht

Downgoat

for making it show time

should there be like a button?

Mᴀʀs Uʟᴛᴏʀ

???

Downgoat

Or are you talking about the console version rather than the online REPL?

Mᴀʀs Uʟᴛᴏʀ

@Downgoat There's an online repl?

Downgoat

cheddar.vihan.org/repl

haven't got the auto-updating script working yet

still need to encrypt my SSH key

Mᴀʀs Uʟᴛᴏʀ

10:48 PM

TIL I've been offline for too long

Downgoat

it's running v0.3.0 but current version is pre-1.0.0-beta.9

Mᴀʀs Uʟᴛᴏʀ

Just in some corner with empty space, 'Calculation took <time>s'

In the console version, just console.log that

Downgoat

maybe when you open the REPL with a flag or somethin

Mᴀʀs Uʟᴛᴏʀ

@Downgoat I was thinking something like cheddar -t and cheddar --time

Downgoat

okay

dont have time to figure out how to do that rn but ill do it later

Dr Green Eggs and Iron Man

10:50 PM

Should we have a computer-science tag?

Mᴀʀs Uʟᴛᴏʀ

note: you should use minimist for flag handling

Downgoat

I'm using commander

I think

CLI is pretty weird ATM

it's some crazy handoff between shell a node forking script, the CLI manager, the REPL, and the program executor

Quill

@DrGreenEggsandIronMan seems a bit meta

Mᴀʀs Uʟᴛᴏʀ

require('minimist')(process.argv.slice(process.argv.indexOf('index.js' + 1)), {
  alias: {
    time: 't'
  },
  booleans: ['time']
})

^something like that would work with minimist

Dr Green Eggs and Iron Man

@Quill yeah, I suppose.

Quill

10:52 PM

> I change my mind. This is very important so I'm targetting targeting it for v1.0.0

Downgoat

oh wait no I'm using nopt i think

@Quill :|

thats not good

i think I should merge the last stable release (v1.0.0-beta.7) but idk :/

Quill

This kinda scares me

Downgoat

one more checkbox left on cheddar :^)

El'endia Starman

@Downgoat I realized a couple weeks ago that it'll basically be pointless to implement a specific ternary operator. If you want to do x = a ? b : c, the Pytek equivalent is x = \if(a){b}{c}.

Q: Is it a max-heap?

A heap, also known as a priority-queue, is an abstract data type. Conceptually, it's a binary tree where the children of every node are smaller than the node itself. (Assuming it's a max-heap.) When an element is pushed or popped, the heap rearranges itself so the the biggest element is the next ...

11:02 PM

@Downgoat Freedom, metaprogramming, functional programming, dynamic typing, extensibility, and generators

Downgoat

ok so i need generators in cheddar

Cᴏɴᴏʀ O'Bʀɪᴇɴ

btw did you do the (op)?

Downgoat

no >_> I have to figure out why (0:13).foo is borked

Cᴏɴᴏʀ O'Bʀɪᴇɴ

because foo isn't a property of the former?

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ like it causes left recursion which is really weird

@MᴀʀsUʟᴛᴏʀ THANK YOU SO MUCH YOUR SOLUTION WORKS 10/10 YOU ARE THE BEST.

@MᴀʀsUʟᴛᴏʀ can you make CheddarShuntingYard support CheddarParenthesizedExpression? :3

@El'endiaStarman huh nice

ahahahaha

idk whats with me and premature celebrations

LegionMammal978

Oh, yeah, still have to work on rationals...

quartata

@Downgoat Generators are extremely easy

At least the actual data structure part.

Can't help you with the parsing

Downgoat

@quartata idk i haven't even designed them yet

@quartata oh im like a guru at parsing shit now

quartata

But basically you're going to want a linked list i.e class Node { var data; var nextNode; } or something like that

Quill

11:33 PM

2ality.com/2016/05/six-nifty-es6-tricks.html

quartata

Then you want a "promise" class, which should be like a special anonymous function in place of the next node that calculates more of the list

When you traverse the list and hit a "promise", you execute the promise and set the first node it returns to the nextNode (or tail)

So basically you have a lazy linked list.

Then you chunk up the function so that everything up to the first yield is a promise, etc..

Quill

oh hey I did one of those the other day

gist.github.com/The-Quill/c6ea3b6e8236337453482a0b89a19bb1

quartata

It's pretty simple

If you just make the generator function return an appropriate one of those you can iterate over it and all that good stuff

Downgoat

cheddar> (1+1)+1
3

yay \o/ \o/

Quill

yeah, I was arguing something about IEnumerable being similar to promise stacks

Downgoat

11:36 PM

i never thought i'd fix that bug

quartata

@Downgoat You get the idea?

Quill

I get the feeling he's not paying attention <_<

Downgoat

@Quill :|

I'll read it in a sec just gotta write this commit message

okay I'll read it now, right after the tests finish running

SirPython

@Quill Those are really cool! I especially like the first one.
