@quartata ye it's nice but hail isn't as much

Downgoat

does anyone have experience with emscripten

mınxomaτ

Some.

Downgoat

12:31 AM

Do you know how it compiles structs?

Like does it generate proper classes in JS

quartata

@Downgoat Most likely as arrays

mınxomaτ

That depends on the target.

quartata

Since it takes LLVM output and LLVM would have already done the structure alignment

mınxomaτ

But it doesn't know anything about data structures. It operates on arrays as memory.

Downgoat

O_o is that not very slow

mınxomaτ

12:32 AM

Dunno what happens if you target WASM.

Downgoat

I am trying to compile flex/bison output

quartata

@Downgoat What do you mean? That's how structures are compiled to any target

mınxomaτ

@Downgoat The point of asm.js is that it's so simple that it can be optimized to the fullest extent.

quartata

each field has an index

@Downgoat Oh god are you doing what I think you're doing

No no I'm putting my foot down

Absolutely not

Downgoat

@mınxomaτ Node does not support ASM.js to my knoledge

@quartata what is so bad

mınxomaτ

12:34 AM

@Downgoat That question makes no sense.

Everything supports asm.js.

quartata

@Downgoat everything

just use a parser generator intended for javascript

Downgoat

@mınxomaτ I mean like "use asm" and it's applicable optimizations

to my knoledge

quartata

@Downgoat asm.js isn't any different from regular JS

It's just a set of rules that leads to more efficient transpiled code when transpiling from a statically typed language

Downgoat

@quartata well syntactically yes

mınxomaτ

quartata

@mınxomaτ Oh, I see what you mean

@mınxomaτ are you kidding me right now

Downgoat

there is jison which was put together as a guy's CS project

quartata

@Downgoat Jison, PegJS, ..?

Downgoat

12:38 AM

then there is Peg.JS which doesn't give full power that I need for cheddar

Qwerp-Derp

What's wrong with PegJS

quartata

@Downgoat How on earth did you make a language that can't be expressed by a PEG

Downgoat

@quartata I am not talking about the algorithm I'm talking about the library

quartata

What's it missing?

Downgoat

From it's docs it looks like it doesn't support parser states like lex

it also doesn't seem like it has a "setup" section to where I can define my variables and stuff

Qwerp-Derp

12:42 AM

tinylisp looks really cool, you can build everything from the ground up

Downgoat

so only solution is to use lex and yacc and compile to JavaScript

Riker

@Downgoat from the recent SO blog post

> Editor's note: American cheese is delicious! Period.

Downgoat

also peg.js apparently doesn't have tokenizer

which is kind of a deal breaker

quartata

@Downgoat I mean, lexing is pretty easy

Downgoat

but am I like supposed to implement lexing in a parser

quartata

12:45 AM

@Downgoat Well, OK. Let me know how annoying that gets for you

Downgoat

that is ugly solutoin

quartata

@Downgoat No?

I mean if you're going for the traditional style parser you just lex in a separate lexer first

That can easily be done by hand

Downgoat

@quartata will it doesn't look like I can pass array of tokens to PEG

mınxomaτ

Who needs parser generators anyway.

Downgoat

mınxomaτ

12:47 AM

A top-down recursive scanner is clearly the way to go :P

Downgoat

oh I tried that with Ches

it was a horrible mistake

it is incredibely slow

mınxomaτ

One day... I will finally get around to porting this to Rust and make it a bit more universal.

Downgoat

I found solution :D nearley.js.org

quartata

@Downgoat Y'know, GCC uses recursive descent..

Downgoat

yes, but IIRC it is all hand written and all for best speed

quartata

12:55 AM

Is Ches not hand written?

Downgoat

A) I am not as smart as very-smart GCC developers B) I don't have as much time C) handwritten parser in JS is bad idea

@quartata yes, it is not good

quartata

I fail to see the distinction I guess is the point I'm getting at. There isn't a massive difference so just use whatever is the easiest

Downgoat

@quartata is Pytek parser hand-written?

quartata

Yes.

So, floor(log(abs(x))) calculates the length

Riker

OK so this is hella weird. Remember that CS169 room I found a while back that had an IRC relay?

I found a similarly named room that appears to be general discussion for what was a StackExchange site

All the URLs redirect to A51 now but judging by the transcript it appeared to be some sort of test for a partnership between SE and edX to provide custom private SE sites for each course

This is so weird. @Doorknob might know more about it since it was around 2014 and he's our resident SE graybeard

I believe the course was Intro to Ruby on Rails judging by some of the chatter in the IRC room

I think Bison has gone crazy. It is saying:

Conflict in grammar: multiple actions possible when lookahead token is . in state 25
- reduce by rule: PropertyExpression -> PropertyHead PropertyTail
- shift token (then go to state 27)

Doorknob

@Doorknob (I also didn't know about this until now, when I was looking through :h I for Downgoat's question.)

Downgoat

but there is no state 27

DJMcMayhem

I would have just said 0i since it's the same byte count

Downgoat

I think that is more key distance though :P

Doorknob

Not repeatable, either.

DJMcMayhem

4:56 AM

@Doorknob that's actually a great point, I didn't think about that

Downgoat

you can record it no?

DJMcMayhem

Yeah, but it's easier to use .

@Doorknob I've been thinking about this for a while, maybe you can help. Frequently I'll want to replace one word with another, so I'll do something like yiw<move to other word>viwp this works great, but it grabs the new word and replaces the register so I can't repeat it. Can you think of a workaround?

I thought of xnoremap p pgvy but I don't always want to do that (like if I'm exchanging two words)

Downgoat

Actually since all vim experts are here rn, does anyone know what is the command that opens the window with the most recent commands used?

DJMcMayhem

@Downgoat q: IIRC

Downgoat

aha

so that's why it keeps opening up by accident

Doorknob

5:02 AM

@DJMcMayhem Yeah, I've had that problem in the past before many times too. I can't really think of anything good other than "_cw<c-r>" maybe, but that feels obscenely clunky.

Downgoat

could I use nnoremap q: :q to fix?

Doorknob

Oh, well you could do viw"0p, which is marginally bettter.

DJMcMayhem

@Downgoat I don't see why not.

Doorknob

@Doorknob Actually, this breaks with . for some reason. The first one doesn't, but it's still awful.

Downgoat

hm. does it seem like this would be a good idea:

DJMcMayhem

5:06 AM

Yeah, I just wish there was a way to specify the to register as well as the from register.

Downgoat

let lambda = n -> for (let i = 0; i < n; i++) { ... }

i.e. letting non-expressions statements be allowed in non-block lambdas?

Doorknob

@DJMcMayhem Well, visual mode breaks . in all sorts of ways anyway (or at least has unintuitive behavior). Better to stay away from it if you want to repeat things.

DJMcMayhem

I'll probably end up doing this:

xnoremap <leader>p pgvy
xnoremap <leader>P Pgvy

(super vague)

def permutations_ending_in_0(n):
    for p in itertools.permutations(range(1,n)):
        yield p + (0,)

def map_to_cycle(p):
    l = [-1 for _ in p]
    pos = 0
    for e in p:
        l[pos] = e
        pos = e
    return l

for p in permutations_ending_in_0(5):
    print(map_to_cycle(p))

this works, but I wonder if there's a better direct way

Anyone use outlook 2016

I occasionally run into a situation where my inbox reports I have unread email but none show up. I click on the Unread button and none are listed. Upon loading more emails from microsoft exchange sometimes I'm able to see the missing emails and other times not.

It's a bit frustrating

@Poke I have the same problem in Outlook 2013. I can fix it logging into Microsofts webmail and marking it as read there.

Poke

@Emigna well at least the mild ocd around the number being there can be solved...

i don't remember seeing this issue in 2013

looking on the google a lot of the answers i'm seeing are "Use Cache Exchange Mode"

but i already have all that jazz

so idk

After hearing horror stories from colleagues upgrading I've decided to stay in 2013 :)

You use Office 365 or just outlook?

Emigna

We have office 365 but I rarely use anything other than outlook

Poke
