I'm wanting multiline outputs

a\na\rb shows a\nb?

TuxCopter

yep

Destructible Watermelon

I want multiline overwrite

TuxCopter

\o/ I finally solved the aquaponics problem in SHENZHEN I/O

@DestructibleWatermelon Then ANSI codes

ANSI escape code

In computing, ANSI escape codes (or escape sequences) are a method using in-band signaling to control the formatting, color, and other output options on video text terminals. To encode this formatting information, certain sequences of bytes are embedded into the text, which the terminal looks for and interprets as commands, not as character codes. ANSI codes were introduced in the 1970s and became widespread in the minicomputer/mainframe market by the early 1980s. They were used by the nascent bulletin board system market to offer improved displays compared to earlier systems lacking cursor movement...

Destructible Watermelon

k thanks

how... how do I use ANSI?

TuxCopter

Every ANSI codes starts with <ESC>[

(\x1b, \033 or \e in most languages is <ESC>)

10:26 AM

wait, to go up one with ANSI, you need to go up two?

hi @xnor

TuxCopter

Welcome to spaghettiland

Destructible Watermelon

is there anyway to detect key presses on terminal?

TuxCopter

By setting the terminal in nobuffering mode

wizzwizz4

@DestructibleWatermelon Alternatively, getc().

Destructible Watermelon

I'm using python...

probably should have mentioned lol

@TuxCopter how...

TuxCopter

10:38 AM

getc is buffered

It wait for a newline

@DestructibleWatermelon stty magic AFAIK

I can't help you on this one

Yes I did

Destructible Watermelon

10:45 AM

That looks like a good game. A chessboard...on a domino!

Destructible Watermelon

hooray

someone made a python function to get keypresses

BUT ITS PYTHON 2

NOOOOOOOO

Destructible Watermelon

Also now my terminal is in a loop

Hooray

You did it tux

time to start making this crap game I was going to make

wizzwizz4

@DestructibleWatermelon I'm sure it's not that bad, if you're investing valuable golfing time into it...

Unrelated, but I keep getting HNQs and I don't know why.

Destructible Watermelon

also I just realised that perhaps getch should have an allowance for ctrl c

also what is the ord value of ctrl c?

wizzwizz4

10:57 AM

@DestructibleWatermelon catch KeyboardInterrupt:?

Destructible Watermelon

wait

@wizzwizz4 ... what

at the moment the loop is unkillable

but for closing the terminal with the mouse or similar

feersum

Can Ctrl-Break kill it?

Actually, I don't know if that does anything in Linux.

Destructible Watermelon

i'm using mac

also I wouldn't know where to put catch

wizzwizz4

@feersum You mean GNU, right? Because Linux is the kernel, and I don't think that handles Ctrl-Break. </pedant>

feersum

Mac? Far enough.

Destructible Watermelon

11:01 AM

I was just going to hard code ctrl c ending the loop

also I realised ctrl c has the code point of ç apparently

wait nvm I was pressing wrong key

wizzwizz4

@DestructibleWatermelon I thought Ctrl unset that bit, not set it.

@DestructibleWatermelon Were you pressing the Meta key (M-c)?

Destructible Watermelon

what is the ord of ctrl c please

@wizzwizz4 accidentally, yeah

wizzwizz4

@DestructibleWatermelon What is the ord of c?

Nvr mind, brb. Getting it.

@DestructibleWatermelon \x03

I think

Destructible Watermelon

also up key registers as three chars

wizzwizz4

@TuxCopter I think so too.

@DestructibleWatermelon It sends through the ANSI code for up.

TuxCopter

@DestructibleWatermelon ~~ANSI code for up~~ dammit

Destructible Watermelon

hmmm, would be nice if there was some way to make it register into one thing

wizzwizz4

Took me about 15 months from first sight of it to know what it meant, but I wasn't searching for it.

@DestructibleWatermelon There is, but it's quite layout-specific and (almost) definitely OS-specific.

TuxCopter

11:06 AM

@DestructibleWatermelon Check for escape character and read until you have the entire code

Destructible Watermelon

ok

I don't know ANSI parsing rules though ;_;

TuxCopter

AFAIK there is some thing to know if there is unread input in the buffer

wizzwizz4

@DestructibleWatermelon !wiki ANSI Code

TuxCopter

Read until the buffer is empty

Destructible Watermelon

@TuxCopter thanks

How to read until buffer empty?

wizzwizz4

@TuxCopter return eval('/replyto "Luke, I am your father"');

@DestructibleWatermelon Keep reading until your program hangs?

TuxCopter

@DestructibleWatermelon There is probably a function in sys.stdin

Destructible Watermelon

wat?

TuxCopter

11:10 AM

method*

Destructible Watermelon

also I thought that writing on a line already written on overwrote what was there

oh wait, nevermind

wasn't the issue

wizzwizz4

ESC[A is up, ESC[B is down, ESC[C is right, ESC[D is left. Sometimes there's a 1 between the [ and the letter, could be another (larger) number if key held down for long time.

Destructible Watermelon

11:26 AM

I think the main thing is reading to end of buffer

I find it kind of weird that the icon for ELU is a latin word

Did you guys actually think we were getting our design on November 1st or was that all just a joke?

wizzwizz4

@quartata I actually thought that we were.

TuxCopter

quartata

Looks like we need to do more meme education in public schools

Geobits has been doing this for years

ASCII-only

@quartata Only public schools?

quartata

@ASCII-only Well we can't tell them what to do

Whereas with public schools we can just make it rain taxpayer money and they'll do whatever

Anyone here know either Haskell or OCaml?

TuxCopter

1:00 PM

I know a fair bit of Haskell

Dada

Some basic of OCaml (and a lot of the implementation of its virtual machine ^^) here

quartata

All right the two of you combined might be able to help me decide. In the past I haven't really tried to learn more than the basics of either ecause the horror stories of their type systems was somewhat off-putting

feersum

Haskell has way more type horror.

It has Nomads.

wizzwizz4

/me faints

quartata

So I was trying to decide which to try first so that I can laugh at how shitty it is compared to Erlang

TuxCopter

1:04 PM

@quartata Haskell's type system has been created by satan

Really

Dada

Huhu! I would recommand haskell over OCaml, I think you'll have more fun with it

Zgarb

Haskell's type system is the best thing since sliced bread.

quartata

@Zgarb I was waiting for you to chime in :P

feersum

Mathematicians always like Haskell ;)

In either one you have the type signatures like a -> b-> c which can look confusing at first, but it's simple once you understand currying and know that -> is right-associative.

quartata

2 votes for OCaml and 2 votes for Haskell. Haskell it is since I know a lot more about it than OCaml

Dada

1:07 PM

@quartata I feel like with OCaml there is usually one "right" way to do something, and you don't have a lot of options. Whereas with haskell you've got more freedom...
