Bash bashing

@El'endiaStarman I haven't tried r=13 yet.

El'endia Starman

@MartinBüttner :'( I had you beat by a byte for a few precious minutes...

What is the algorithm everyone is using for the chessboard?

El'endia Starman

What I do: read ASCII, read number, add, modulo 2, then print "dark" or "light" based on that.

Martin Büttner

@El'endiaStarman don't know much Befunge, but I'm sure it's more likely that you'll be able to golf yours even further than I mine

El'endia Starman

12:02 AM

I'm actually pretty doubtful of that.

Anonymous

Read string, explode to ordinals, add, mod 2, print "dark" or "light"

Martin Büttner

oh right, I could have added them as well...

El'endia Starman

5 bytes for the read, add, and modulo 2; 1 byte for the decision; 6 bytes for "dark" and 7 bytes for "light", and 6 bytes for output. That's 25 bytes altogether. The other 8 bytes are taken up by 3 newlines, 4 directional arrows, and 1 space to avoid outputting "dar k".

Well, that's in the latest version of the program, which has no advantage over the previous 33 byte solution because it too is 33 bytes.

I think I finally figured out what was wrong with my IDE

@flawr I'm going to do something about this Java hate.

Anonymous

@quartata Ban Java?

I'm going to develop a revolutionary new Java library for code-golf.

@quartata I never said I hate Java! I even submitted answers in Java!

Here's a sample:

12:39 AM

@Mego how do you do if, else, while, and for statements in Seriously?

@TanMath You do not.

class A{public static void main(String[]a){new C("ri){mf1>},,_,f{){_@\%}h)=}1b");}}

@flawr how come?

For this challenge: codegolf.stackexchange.com/questions/63710/calculate-phi-not-pi

that would be so funny

12:40 AM

I bet you can't figure out how it works.

just import the CJam interpreter and Java can be super short!

Anonymous

@TanMath There's not an explicit for loop, only while. W<code>W executes <code> while the value on top of the stack is truthy (it doesn't pop). If is done with I: it pops a, b, and c, and pushes b if a is truthy else c

hehe

@Mego example code please?

That would be fun, implement a whole cjam interpreter in java, and submit it with the cjam code. I bet you would still be shorter than conventional java answers=P

12:42 AM

@flawr The CJam interpreter is in Java

That sounds as if there was only one CJam interpreter?

Anonymous

@TanMath 5W.DW will print 5 4 3 2 1 (separated by newlines, instead of spaces). "divisible by 2""not divisible by 2"2,%I. will print "divisible by 2" if the input number % 2 == 0, and "not divisible by 2" otherwise

@flawr is there another one?

Anonymous

Except apparently I broke loops

@flawr All the web interpreters just call the Java one

12:46 AM

@aditsu The online interpreter

Oh, I thought it was implemented in Javascript.

oh no no no no no honey

it's mostly the same java code, automatically translated to javascript

Why no honey? Honey is delicious.

Well then it is javascript=)

But Javascript is just Java, right?

Almost=)

12:47 AM

not really

Just remove the script.

@flawr So instead of <script>code</script> you do <>code</>?

No it really is quite different, I think I am quite good at Java, but JavaScript still leaves gives me headaches.

Well I was not quite sure, but it is a bit more difficult to judge in a foreign language.

El'endia Starman

12:51 AM

yeah :/

On a different subject...

I'm trying to implement string escaping in Minkolang.

sounds fun

El'endia Starman

How do I go from having \t as two separate characters to one tab character?

Before you add the character to the string buffer, check to see if it is a `\`

El'endia Starman

In Python, that is.

If it is a `\`, don't add it to the buffer and set a flag to escape the next character

12:52 AM

Regexery?

then on the next char, if the flag is set and the char is t, append a tab to the string buffer

El'endia Starman

@phase That doesn't help. I still have two separate characters that have to become one.

@El'endiaStarman Don't think of it that way

I just read the news. :/

Are you going character by character in a loop?

El'endia Starman

12:54 AM

And it has to work for \n, \', \", etc...

Yes.

@El'endiaStarman youtu.be/Hqs_9p9iMRU?t=1050 (nsfw)

@El'endiaStarman Do you have a check for " to start/stop string parsing?

El'endia Starman

@phase Yep.

MORBID MINUTE: Coffins vs. Caskets

@El'endiaStarman Add another check for \` and set another flag for escape

Hmm... Passing code via the -c flag in Seriously isn't working right now

A lookup table is probably your best bet

El'endia Starman

12:58 AM

@phase But what if I want support for stuff like unicode escaping?

@Mego That is stuff I think you might be interested=)

El'endia Starman

Actually, if I want to be able to do \x0000 escapes, then I'd finish the string buffer and then escape-convert everything in it.

But \x0000 is \\x0000 internally...

Maybe I can use eval...

No, doesn't look like that works.

Ta-da! Googled and here's the answer I was looking for!

@El'endiaStarman The way I do this in Rotor is search for '\' while parsing the string, and then just take it and the next char and evaluate it using Eval.me

so like if you have \t it pushes Eval.me("t");

btw, your code only prints 5 @Mego

It's a terrible hack but it works

El'endia Starman

String escaping works!

1:11 AM

I wrote a Rotor one but it relies on four unimplemented features :(

It's a pretty cool challenge, at any rate.

@El'endiaStarman \o/

El'endia Starman

@quartata and @phase: only took me 4 lines of code, and 3 of those lines are solely for setting the escape flag (for the whole string).

@El'endiaStarman Cool.

I probably should add something for not escaping strings in Rotor.

I honestly don't know what the conventions for stack-based languages are. I made ; pop because that's what CJam did.

I actually did a lot of things because CJam did them. Maybe not the best design method

@quartata There hasn't been an update. I just chose it for the right tasks. I don't think it would be very competitive in elaborate challenges.

@El'endiaStarman python is not a golfing language? But ShortPy, my first and latest language in creation will be!

@TanMath Do you know what Pyth is?

@Dennis Hm

The PhiNotPi challenge was basically builtin-weird_chars-builtin.

El'endia Starman

@quartata It's diverged from being short Python.

1:36 AM

@El'endiaStarman It's still basically short Python.

@quartata yes...

@TanMath Just wanted to make sure you knew it had been done before

Pyth is what happens when a mommy and a daddy love each other very much.

El'endia Starman

...o.O?

But if you can make it more like Python and not some golfing black pudding monster that's cool

1:37 AM

ShortPy takes inspiration from Python and C++, with shorter syntax, and 1 to 3 character syntax for builtin functions.

@AlexA. now, one of the parents is Python, the mystery is, who is the other one!

1:38 AM

@aditsu oh jesus

@El'endiaStarman You know, I hate to suggest you rip off my language

@TanMath Isaac, of course ;)

But you should use control characters for 10+

@AlexA. um...

El'endia Starman

@quartata How do you mean? Control characters?

1:38 AM

Like ASCII control characters.

@AlexA. well, that's what it looks like :p

Like Control-C and all that.

@AlexA. the parents were supposed to be languages!

That way it is one byte.

@aditsu Haha says you, the creator of its competitor. :P

El'endia Starman

1:39 AM

Minkolang is strictly limited to ASCII 10 and 32-126.

Why strictly?

El'endia Starman

Because I want it to be easily type-able.

@TanMath Well Pyth didn't make itself; Isaac forged it using steel, love, and a bit of Python.

@El'endiaStarman You can type control characters easily in vim.

El'endia Starman

Minko 2.0 (whenever I make it) will certainly use a more inclusive encoding, like CP437.

1:40 AM

Control - V followed by Control - char

El'endia Starman

@quartata 1) Windows, 2) I'm keeping it within printable ASCII.

@El'endiaStarman Oh, fair enough

@quartata Nobody uses vi. Some people use vim, but mostly just Doorknob.

@AlexA. There fixed jeez

Much better. Seriously, who uses vi anymore?

1:41 AM

vi = vim on Ubuntu. That's why I typed that

@TanMath One thing to consider: Will it ever beat Pyth? If not, I suggest to make being fun to golf in a higher priority than being very short.

@El'endiaStarman Link me teh code!!!

And now... a new and improved 4-bit adder!

El'endia Starman

@phase What codeh?!?

Some people make cool computer stuff in Minecraft. I stab monsters and eat apples and shit.

El'endia Starman

1:44 AM

Here's some...?

@AlexA. Stabbing monsters is fun as well.

@ThomasKwa true.. I am writing a language that is simple and intuitive to understand.. The major advantage will be its compatibility with Python, meaning Python code and ShortPy can be mixed with no error as the ShortPy code is converted to Python code (as with Pyth). Also, I will design a program converting Python to ShortPy so you can write it originally in Python, and a program will golf it for you.

@AlexA. what language is @aditsu writing?

@TanMath Aditsu wrote CJam.

He made CJam!

Ninja'd

That basically makes him our king around here.

1:46 AM

hahaha

Although, Pyth has more votes than CJam on Phi's meta post that lists languages made by users.

@AlexA. That reminds me. I need to make a Rotor post.

@AlexA. where is this?

El'endia Starman

But...Pyth? Then again, CJam was basically first...wasn't it? Golfscript was first, but wasn't made by a user?

GolfScript wasn't made by a PPCG user, no

1:47 AM

@El'endiaStarman GolfScript is from liek 2007
