The Nineteenth Byte

phase

8:00 PM

@Stefnotch What comments at the top are required?

Maltysen

@orlp Can I use your first n primes technique? It's one byte shorter than mine.

orlp

@Maltysen its not mine

so go ahead \o/

or I guess it is mine

Maltysen

k thanks

orlp

47

A: Is this number a prime?

Pyth, 4 bytes }QPQ Prints True or False.

Maltysen

Tied with J now ^.^

orlp

8:11 PM

NOOOOOOOOOOo

YOU BEAT ME?!

BEATEN BY A MORTAL?!

@Maltysen if Pyth had a factorial builtin we could make an especially terrible but short way of finding the first N primes

@Maltysen uniquifying factoring factorial N

El'endia Starman

There's a mod (chat) flag...and the flagged message, the flagger's message, and the room name are all in Portuguese.

Well, I'm not touching THAT one.

Doorknob

@El'endiaStarman see TL

tl;dr translate: is useful

Maltysen

@orlp It does

orlp

@Maltysen hrm?

Maltysen

it has a factorial builtin

.!

orlp

8:20 PM

huh

I messed up then

because I thought I searched the docs for 'fac'

Maltysen

but it isnt shorter

{P.!+3Q

orlp

oh wait, that for the primes UNDER Q

not the first Q primes

Maltysen

oh ok then

but if he wants us to go to max 27...

Q: Processing custom MenuBar is not displaying

I have created a custom MenuBar in my Processing sketch (using Eclipse as my IDE), but it is not displaying. Here is a MacOSX MenuBar. Below is my code. The project is called ProcessingTrials and the class is called ProcessingSketch. I am running the program as a Java Application. I have created...

orlp

why are you asking us?

Kριτικσι Λίθος

8:23 PM

dunno

just making my question more popular so that people would actually pay attention to it

El'endia Starman

@KριτικσιΛίθος 1) It's been 20 minutes, and 2) you get quick answers on simple questions, and not-so-quick answers on not-so-simple questions.

Kριτικσι Λίθος

@El'endiaStarman OK then, I will wait till the next day...

orlp

I'm thinking of a challenge

where the input is a grammar

and your program must produce the FIRST and FOLLOW sets for each nonterminal

ETHproductions

Dangit, broke my interpreter with mismatched parentheses

I wish Notepad++ had a syntax-checking feature

(Of course, there's probably a plugin for that...)

FlagAsSpam

@KριτικσιΛίθος I know how to do that actually :D

ETHproductions

8:39 PM

That's better

orlp

@ETHproductions install vim

quintopia

@ETHproductions it already shows matched parens... what exactly do you need it to do?

ETHproductions

@quintopia Alert me when they're mismatched so I don't have to check each line manually :P

Doorknob

orlp knows what he's talking about :P

quintopia

vim is okay. i would be surprised is @ETHproductions doesn't have it installed already

orlp

8:42 PM

be like me

and you'll be golfing at top speed

ETHproductions

@quintopia I don't have it installed already

orlp

I always feel like an arcane wizard whenever I post screenshots of my editor in my golf workflow :P

Doorknob

@orlp I do that except with separate i3 terminals instead of vim splits cause it's easier to navigate :P

Oh also an extra terminal with a REPL in it

orlp

@Doorknob look at the bottom

those are 9 terminals

Doorknob

ahhh I see

i3? Or a different WM?

orlp

8:44 PM

terminal #1 is always running a Python repl with a custom environment with a lot of utility functions and imports

@Doorknob this is all one terminal

Doorknob

wait what

45 secs ago, by orlp

those are 9 terminals

orlp

@Doorknob you could SSH into my box and see exactly this image

@Doorknob welcome to the world of terminal multiplexers :)

Doorknob

Oh, so you're doing it through some sort of multiplexer?

ninja'd

I occasionally use tmux but I usually find i3 keybindings to be more efficient

orlp

tmux.github.io

Doorknob

ha, re-ninja'd :P

orlp

8:45 PM

that's vim running inside tmux

with regular vim splits

(I don't really use tmux splits, I'm not used to them)

Maltysen

I don't know too much about this, but doesn't the default ubuntu shell let you do this?

ETHproductions

I am so not up-to-speed with this conversation...

El'endia Starman

Me neither. :P

Doorknob

@Maltysen a shell is not a terminal

ETHproductions

I guess that's what I get for only getting into programming 1.5 years ago :P

orlp

8:46 PM

@Doorknob 90% of my workflow consists of ctrl + b + b to swap between vim/command line inside tmux and alt-tab to switch between terminal and browser

Doorknob

@ETHproductions tmux stands for terminal multiplexer. It's got fancy server stuff, but what I mostly use it for is just splitting terminals into separate kajiggers.

Maltysen

@Doorknob oh yeah that's what I meant

Doorknob

Ubuntu's default is gnome-terminal, yeah?

FlagAsSpam

@KριτικσιΛίθος You need to use:

import com.apple.eawt.Application;
import com.apple.eawt.ApplicationEvent;

orlp

a really cool part about tmux is that I could close my terminal, open it again and write tmux to get back where I was

Maltysen

8:47 PM

@Doorknob yeah

orlp

or I can SSH into this machine, write tmux, and share the session

Doorknob

Yeah, that's the fancy server stuff I mentioned earlier :P

orlp

or you could SSH into my machine, and we could share the same session

Doorknob

@Maltysen gnome-terminal doesn't do multiplexing

@Maltysen ^

You get way more than just splits too

Maltysen

oh wow

orlp

8:50 PM

@Maltysen try this

sudo apt-get install tmux

tmux

echo hello world

close your gnome-terminal

open up your gnome terminal

tmux

FlagAsSpam

Oh hay, I found something interesting: you can use applescript as script engine in Java.

Didn't know that.

implements in Vitsy

Maltysen

@orlp it didn't work

Doorknob

tmux ls?

You may have to re-attach to the session thingy manually

Maltysen

it gives me four of them.

@Doorknob ah like screen?

Doorknob

huhwhat

@Maltysen yes

orlp

8:52 PM

@Maltysen wat

Maltysen

no I tried a bunch of times

orlp

@Maltysen tmux is a modern alternative to GNU screen

@Maltysen maybe you need to write tmux attach

on my system that's the default behavior

Doorknob

Oh, so you've created four different tmux sessions

Maltysen

is there a way to kill all of the other ones first?

Doorknob

tmux kill-session I think

tmux kill-session -a

Maltysen

8:54 PM

oh cool attach worked

so, will it run in the background like screen?

Doorknob

yep

ETHproductions

The best thing about creating a code-golf language is that you can go "Aw man, this program would be so much shorter if my lang had this feature" and then go and implement that feature.

orlp

@ETHproductions that's not the best thing

Doorknob

@ETHproductions and then you can't use it in the challenge :(

orlp

the best thing is "Aw man, this program would be so much shorter if my lang had this feature"

then you find out that Pyth had it anyway

9

Doorknob

8:55 PM

hahahaha

ETHproductions

LOL

Maltysen

Pyth has all the features

ETHproductions

@Doorknob Yeah, but then you can use it in the next challenge that requires it (and then you wait for a million billion years and the earth burns up and the universe collapses and you're still waiting for that next challenge)

El'endia Starman

@ETHproductions Afterlife confirmed!

orlp

@El'endiaStarman [citation needed]

I'll believe the bible when it's published in a peer-reviewed journal :P

7

El'endia Starman

8:59 PM

DARN. Ninja'd...

Maltysen

so how do I split tmux?

El'endia Starman

I was just about to suggest the Bible... :P

Doorknob

@Maltysen <C-b> ", <C-b> %

lots of people remap <C-b> to <C-a>

orlp

@Doorknob don't

Maltysen

oh wow it really is like screen

Doorknob

8:59 PM

@orlp I do. Why shouldn't I?

orlp

@Doorknob ctrl+a is a vim keybind :P

ETHproductions

Hey, the good news is this single feature can be extended to a bunch of handy features, saving 3 bytes in about 20% of all Japt programs :D

orlp

7 mins ago, by orlp

@Maltysen tmux is a modern alternative to GNU screen

Doorknob

@orlp Heh, right, but I usually don't do vim in tmux though

(I use separate i3 terminals and/or vim splits instead)

Maltysen

but this shows up as only one window in tmux ls?

Doorknob

9:00 PM

one session

orlp

@Maltysen splits aren't the best feature

type ctrl+b c

Doorknob

There's basically the only thing I use tmux for :P (which I've been planning to fix, but never got around to learning more stuff)

Maltysen

ah so the numbers at the bottom go from session to session?

Alex A.

Irrelevant to the current conversation, but @orlp: Any plans to continue development of Pyth 5?

orlp

@Maltysen window to window

@AlexA. yes

Maltysen

9:02 PM

so each session has multiple windows, and each window has multiple splits? *mind blown*

orlp

yes

Doorknob

yep :D

Alex A.

@orlp Oh good. :) I was chatting with Isaac yesterday and he seems unsure whether the project would continue.

orlp

windows are the best feature IMO

Maltysen

how do I switch from split to split?

orlp

9:02 PM

@Maltysen ctrl+b <num>

but to switch back and forth between the latest

Alex A.

@Doorknob What are vim splits?

orlp

use ctrl+b b

@Maltysen oh, SPLIT to SPLIT

thought windows

Maltysen

yeah

orlp

ctrl + b hjkl

like vim's hjkl

@AlexA. opening multiple buffers side-by-side in vim

FlagAsSpam

> hjkl

Doorknob

9:04 PM

@AlexA

Yeah, technically the correct term is "buffer" :P

orlp

@Maltysen actually

Doorknob

Awesome feature for ex. vimdiff.

orlp

I think those are my custom binds

Alex A.

@Doorknob What is ex. vimdiff?

orlp

yeah

@AlexA. vimdiff is amazing

Alex A.

9:05 PM

@Doorknob That's really neat!

orlp

@AlexA. just try this

Alex A.

However, ಠ_ಠ at starting your line numbers at 0.

orlp

copy a file, edit some random stuff

Doorknob

It's diff but it's a million times better

orlp

then run vimdiff file1 file2

@AlexA. nope

Doorknob

9:06 PM

I use relativenumber

orlp

you're misunderstanding his feature

he's using relative line numbers, they go + downwards and upwards

Doorknob

Alex A.

Ohhhhhh okay

Weird. O_O

Doorknob

because counting is too hard :P

orlp

I prefer regular line numbers

Alex A.

9:07 PM

Same

orlp

although I've seen a plugin that I should probably install

Dennis

38 secs ago, by Alex A.

Weird. O_O

Alex A.

Is there a way to use vimdiff to see the difference between git commits?

Doorknob

yes

Actually, with Fugitive it's so awesome it should be illegal (ha)

:Gdiff from within vim

orlp

@Doorknob you're doing it wrong though

Alex A.

9:08 PM

Can I install Fugitive with Pathogen?

Doorknob

Doing what wrong?

@AlexA. yeah

orlp

@Doorknob :set number :set relativenumber

do both

Doorknob

Too ungolfy. :se nu rnu :P

But I didn't know that was possible; nice

Alex A.

How do I do a vim split without a diff?

orlp

@AlexA. :split <name>

Doorknob

9:09 PM

eh, actually, takes up screen real estate for no good reason. It only shows the current line number, which is visible on the status line (in my config at least) anyway

orlp

or :vsplit <name>

Doorknob

Or <C-w> s or <C-w> v

I prefer the C-w variants

Alex A.

@orlp Is this horizontal split and vsplit is vertical split? Will it use relative paths or do I have to specify the full file path?

Doorknob

Relative or full path, of course

split / C-w s is horizontal

orlp

@AlexA. yes and just like any other path in vim (relative)

Alex A.

9:11 PM

Oh okay

orlp

just to prevent confusion

El'endia Starman

/me is proud of my extended explanation

Alex A.

@Doorknob Using control makes me feel like I'm using Emacs and then I feel dirty all over.

orlp

horizontal split means that the window is SPLIT HORIZONTALLY

quintopia

9:11 PM

@orlp does that automatically show the appropriate line of the Pyth docs as you type? I NEED THAT

Doorknob

@AlexA. haha

orlp

so the windows are actually above eachother, vertically

Doorknob

^

orlp

@quintopia what?

Alex A.

@orlp Is that not what horizontal split usually means?

Doorknob

9:12 PM

@quintopia that's just a / in vim...

orlp

I pretty much only use vsplits with the exception of quickfix and my golfing setup

Doorknob

(assuming you're referring to the screenshot way back)

orlp

@AlexA. yes, but in my mind I always get them twisted

Alex A.

Oh okay

Doorknob

me too :P

orlp

9:12 PM

I mean

look at your screen

Alex A.

I am

FlagAsSpam

I got my android emulator to connect to my PS4 and use the Pip-Boy app. c: I'm fangirling so hard right now.

quintopia

@Doorknob exactly. I would love to be typing in one window and have the appropriate / search be issued in the other window as i type

orlp

it's 16:9 or worse

why would you want to split that horizontally?

Doorknob

@quintopia oh, no, that just looks like a regular search

quintopia

9:13 PM

@Doorknob not cool enough

Alex A.

@orlp ¯\_(ツ)_/¯

Doorknob

How would you expect it to work? Constantly search for the last three chars you typed, or something?

orlp

@Doorknob tokenize source file

search for token cursor is currently on

that'd work with Pyth

Doorknob

ah

you could plugin that

orlp

@Doorknob ugh

I hate vimscript

Doorknob

9:16 PM

haha me too

orlp

WHY IS THIS CHAT ALWAYS THROTTLING ME IT'S SO ANNOYING

Doorknob

^

orlp

even mods get throttled?

that's just hilarious

Doorknob

Yup.

Same rate limit as every single other user >.<

Alex A.

Everyone does

Doorknob

9:17 PM

At least we don't get the hair-ripping-out-caliber-annoying "you may only comment once every 15 seconds; timer reset" thing

Alex A.

@orlp You usually send a larger number of short messages in rapid succession. I do that sometimes but most of the time I make longer messages to avoid the throttle. I also find it quite annoying.

@Doorknob Oh jeez, what does that?

Doorknob

Comments

You've never had that happen?

orlp

"Please do not edit your comment ..."

WHY ARE YOU MAKING ME WAIT FOR NO DISCERNIBLE REASON

@AlexA. it's almost as if this is a chat room

Alex A.

@Doorknob No, I do the same thing I said before: fewer long messages.

@orlp Haha ikr

orlp

if you type out full paragraphs (or sometimes even sentences) the other person loses interest or you get ninja'd

Alex A.

9:19 PM

You could feature-request on Meta.SE but they probably have the throttle set at its current value for a reason.

orlp

it's not a simple limit though

Alex A.

Isn't it?

orlp

if you've been actively chatting in the last minute, your throttle triggers earlier and harder

Doorknob

No, you can post 2 messages in rapid succession like

this

Alex A.

I didn't

know that

what if

orlp

9:21 PM

@Doorknob a minute or so ago I got throttled on my second message

Alex A.

I send

that

more than

Doorknob

@orlp That happens when you're really close to the rate limit from before then

orlp

@Doorknob that's my point

it's not a simple limit

Doorknob

right

orlp

it keeps track of your messages in the last window or something

Recursive macros are pretty nifty. They let you omit the 100 if you want to go all the way to end of file

I want to get compress layer data from tmx file . Who knows libraries for decompress gzip and zlib string in javascript ? I try zlib but it doesn't work for me . Ex , layer data in tmx file is : <data encoding="base64" compression="zlib"> eJztwTEBAAAAwqD1T20JT6AAAHgaCWAAAQ== </data> ...
