Nice variety of lighting conditions

Nathan Merrill

@QPaysTaxes are you doing stay alive processes?

trichoplax

Perhaps disturbingly, the garden continues growing after you close the window - the plant pots appeared in mine while my computer was off, and I found them when I followed the link I posted earlier.

Nathan Merrill

aka, do processes stay alive from one function call to another?

trichoplax

00:04

@QPaysTaxes I can't imagine how it could be done without storing them all server side, which seems expensive given xkcd's popularity and the fact that I can open arbitrarily many gardens independently in different tabs...

Alex A.

@EasterlyIrk What are you laughing at?

Zizouz212

I got something!!!!!!!

A big random stick

trichoplax

I thought maybe the url stores the date and time created and a random seed, so it can work out how much garden to show at any future time, but then I realised you can delete things without changing the url, so it can't be that

Nathan Merrill

00:05

@QPaysTaxes well, it totally depends on how Ruby works. At least in python, there was a bunch of stuff that I had to do to make it work (to cover edge cases)

trichoplax

@Zizouz212 It's swaying...

Doorknob

@Zizouz212 I got two big random sticks >_>

Zizouz212

It's moving!

It's growing...

Whatever phone Randall Munroe has, I want it. It comes with italics.

'If you're done being pedantic, we should get dinner.' 'You did it again!' 'No, I didn't.'

Doorknob

00:08

@CᴏɴᴏʀO'Bʀɪᴇɴ xkcd oneboxes please don't direct link images

Downgoat

I think iMessage works with italics

trichoplax

@CᴏɴᴏʀO'Bʀɪᴇɴ I'm guessing that's just email...

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I thought I did do a xkcd link O_O

@QPaysTaxes But not the actual site

@trichoplax With the little arrows on either side?

trichoplax

@CᴏɴᴏʀO'Bʀɪᴇɴ Good point...

Downgoat

are multiline comments really important? Should I include them in Cheddar?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

00:10

YES

I use them all the time.

Downgoat

like within expressions

they will be valid at the end of a line or on their own line

Does anyone do anything like:

2 + /* very difficult to parse comment */ 2

@QPaysTaxes github.com/vihanb/Cheddar

It's a programming language

trichoplax

@Downgoat Please don't make this possible

Cᴏɴᴏʀ O'Bʀɪᴇɴ

How is it difficult?

Downgoat

@trichoplax it is possible in C?

@CᴏɴᴏʀO'Bʀɪᴇɴ because you're not expecting a comment.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

When a /* token is found, just scan until you find a */ tokn.

trichoplax

00:11

@Downgoat Does Cheddar inherit from C??

Downgoat

Like should: 3/*comment*/4 compile to 34?

Doorknob

@Downgoat treat comments the same as whitespace

Downgoat

that was I was thinking

trichoplax

@CᴏɴᴏʀO'Bʀɪᴇɴ I think that was meant as difficult for a human to parse the surrounding expression

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Downgoat what did you mean?

Downgoat

00:13

any ideas on how I would write a grammar for that?

Doorknob

replace /* ... */ with <space> pre-compile time

Easterly Irk

Pages vs Word

@AlexA. wtf

Doorknob

@QPaysTaxes oh I didn't know whether it was interpreted or not

Cᴏɴᴏʀ O'Bʀɪᴇɴ

^^^^

Downgoat

C -> W
     /* C'
C' -> [^/]C
      [^*]

would that work?

Doorknob

00:14

@EasterlyIrk the real answer is "neither" :P

Nathan Merrill

@QPaysTaxes communication timeouts, and detecting when languages were finished communicating

Downgoat

@AlexA. poor snakes ;-; pls remove, very disturbing

Doorknob

@AlexA. O___O

trichoplax

@AlexA. The physics seems off in this simulation... :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@EasterlyIrk The answer is C, (La)TeX

^^^^^

Doorknob

00:15

This is just fantasy

trichoplax

@QPaysTaxes Lol I know - I was joking because it looks really odd. Hence the :P

Cᴏɴᴏʀ O'Bʀɪᴇɴ

I always assumed that I was Alex, just painfully unaware.

Easterly Irk

@CᴏɴᴏʀO'Bʀɪᴇɴ Not for essays no.

Alex A.

@CᴏɴᴏʀO'Bʀɪᴇɴ ?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

00:16

@EasterlyIrk Yes.

Nathan Merrill

@QPaysTaxes in python killing a process that is piped is really tough, and often times languages will have to send "flush()" to actually send the output

@QPaysTaxes right, but if you are waiting on a process to finish, you can't send communication

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@QPaysTaxes You're always "QPaysTexas" to me.

@QPaysTaxes No, but Q is.

Downgoat

@CᴏɴᴏʀO'Bʀɪᴇɴ oh no, I forgot to pay my Texas

Nathan Merrill

@QPaysTaxes right, which depending on your OS and framework, can be really tough

I can't speak for Ruby

my parser is so efficient :^) the above is the generated parse tree for [0+1,2]

it's okay, I'm making a prune() function which will remove all the junk

Zizouz212

It's readable. That's an achievement.

Downgoat

I strive to make my parse treats as readable as passible

treat === tree

how did I write treat instead of tree ._.

Maltysen

@Downgoat you're a goat and trees are treats for them

26 mins ago, by Downgoat

does anyone know how code optimizers work?

pls halp

Alex A.

They optimize the codes

Downgoat

but how?

Alex A.

Surely @Optimizer would know.

Downgoat

@Optimizer can you optimize cheese?

Mars Ultor

@Downgoat Code optimizers?

As in compiler optimizers?

Downgoat

00:29

yes

I need to write one for cheddar

Mars Ultor

They just replace common patterns with more optimized versions

Downgoat

like hardcoded patterns?

wow

Mars Ultor

But for interpreters, PyPy is a good example. It uses JIT and memoization

@Downgoat Yeah, it's kinda surprising how much some common patterns come up

quartata

@Downgoat You're doing premature optimization

Downgoat

@MarsUltor ok, I don't know how that works though

quartata

00:31

Get the interpreter working first then worry about optimizing

Downgoat

@quartata I got the tokenizer working

Zizouz212

Dat ^^

Downgoat

so I should be optimizing then interpreting

right?

quartata

Don't even begin to think about how to handle optimization now

Mars Ultor

Memoization = record the results for each input, use the lookup table if the value has been run

Downgoat

It's okay, I make me cry too.

Downgoat

I make myself cry whenever I try to outgolf Dennis

Maltysen

@AlexA. I don't understand what you mean by not liking Spaceballs

quartata

OK, I know you guys are going to hate me for this but the newsreader is so damn close to being done I'm just going to stomach the JS and finish it

Downgoat

00:37

+100 for JS

I don't like leaving things incomplete, sorry

@Downgoat no

@quartata Then throw it out, problem solved

Oh, lol. They were looking for an answer of one or the other, not "yes". :P

@CᴏɴᴏʀO'Bʀɪᴇɴ I'm going to have to disagree with that. Marie and Bruce was as difficult to endure as a 90 minute conversation between Jar Jar and Chewbacca.
