[今の年]もう家に帰る


31

現在、対応するチャレンジ年ではないほとんどのチャレンジについては、これを前に述べています。

今年はもう[今]年です。

このテキストを現在の年に置き換えて出力する必要があります。


I / O

入力:なし。

出力It's [year] already, folks, go home.[年]が現在の年に変更されました。

入力を受け取ってそれを無視することはできますか(つまりString goHome(Object foo){return "It's "+currentYear()+" already, folks, go home.";}、もちろん(ただし、はるかに短い)行に沿って何かを行います)。

Bash、45文字

printf "It's %(%Y)T already, folks, go home."

printfバージョン4.2に組み込まれているBash には%(fmt)Tフォーマット指定子があり、バージョン4.3以降では、引数がない場合のデフォルトは現在のタイムスタンプになります。

サンプル実行:

bash-4.3$ printf "It's %(%Y)T already, folks, go home."
It's 2017 already, folks, go home.

バッチ、45バイト

@echo It's %date:~6% already, folks, go home.

Batch is actually reasonably competitive for once.

x86 machine code on DOS - 62 bytes

Even though the input from the BIOS is in BCD (as opposed to the plain 16 bit value got from the equivalent DOS call), decoding it to ASCII turned out to be almost as long as base-10 printing a register. Oh well.

    org 100h

section .text

start:
    mov ah,4
    int 1ah             ; get the date from BIOS; cx now contains the year in packed BCD
    mov di,placeholder  ; put di on the last character of placeholder
lop:
    mov al,cl
    and al,0xf  ; get the low nibble of cx
    add [di],al ; add it to the digit
    dec di      ; previous character
    shr cx,4    ; next nibble
    jnz lop     ; loop as long as we have digits to unpack in cx
    mov dx,its
    mov ah,9
    int 21h     ; print the whole string
    ret

its:
    db "It's 000"
placeholder:
    db "0 already, folks, go home.$"

Mathematica, 58 bytes

"It's "<>ToString@#<>" already, folks, go home."&@@Date[]&

Anonymous function. Takes no input and returns a string as output. No, I'm not going to make a REPL submission, post it yourself if that one byte is so important.

TI-Basic (TI-84 Plus CE with OS 5.2+), 64 bytes

getDate
"It's "+toString(Ans(1))+" already, folks, go home.

TI-Basic is a tokenized language. Some commands (getDate, toString(, etc.), and all lowercase letters are two-bytes and everything else used here is one byte each.

Explanation:

getDate                                             # 3, store {Y,M,D} in Ans
"It's "+toString(Ans(1))+" already, folks, go home. # 61, implicitly return required string with Y from getDate

TI-Basic (TI-84 Plus CE with OS 5.1), 108 bytes

{0,1→L1
getDate
Ans(1)L1→L2
LinReg(ax+b) Y1
Equ►String(Y1,Str0
sub(Str0,1,length(Str0)-3→Str0
"It's "+Str0+" already, folks, go home.

TI-Basic is a tokenized language. The more complicated user variables (Y1, L1, L2, Str0), some commands (LinReg(ax+b , getDate, sub(, Equ►String(, length(), and all lowercase letters are two-bytes and everything else used here is one byte each.

OS 5.2 added a toString( command, which obsolesces about half of this submission, which is based off of this algorithm.

Explanation:

{0,1→L1                                  # 8 bytes
getDate                                  # 3 bytes, store {Y,M,D} list in Ans
Ans(1)L1→L2                              # 10 bytes, multiply L1 by the year and store in L2
LinReg(ax+b) Y1                          # 5 bytes, take a linear regression of the points specified by each pair of corresponding coordinates in L1 and L2 and store it in Y1
Equ►String(Y1,Str0                       # 8 bytes, convert Y1 to a string
sub(Str0,1,length(Str0)-3→Str0           # 18 bytes, remove the "X+0" from LinReg
"It's "+Str0+" already, folks, go home.  # 56 bytes, implicitly return the required output

you can inline L_1 in the 5.1 programs. gets rid of a newline, two "L_1" tokens, and a →. 6 bytes saved?
striking

@striking LinReg(ax+b) uses L_1 and L_2, so I have to set them both.
pizzapants184

Save some bytes on the first: use max(getDate) instead because the largest number in getDate is always the year.

JavaScript ES6, 56 bytes

_=>`It's ${Date().split` `[3]} already, folks, go home.`

Try it online!

const f = _=>`It's ${Date().split` `[3]} already, folks, go home.`

console.log(f())


+1 Exactly the solution I was about to post. You could also use substr(11,4) or slice(11,15) instead of the split.
Shaggy

Don't you require more than 56 bytes as part the challenge is to output it?

@cnorthfield Generally speaking in code golf, a function that returns a value is an acceptable answer unless the question has more specific requirements. Check out this and this.

@powelles Thank you for explaining

That is true @powelles, but your answer doesn't return anything unless more is added to your golf.

This will not work in version 2 of PowerShell (the foreach syntax). So you should have a v3+ identifier on here. Cool other wise.

C#, 58 bytes

()=>"It's "+DateTime.Now.Year+" already, folks, go home.";

Anonymous function which returns the required string.

Full program:

using System;

public class Program
{
    public static void Main()
    {
        Func<string> f=
        ()=>"It's "+DateTime.Now.Year+" already, folks, go home.";

        Console.WriteLine(f());
    }
}

I think you can save characters by using C# 6 strings: $"It's {DateTime.Now.Year} etc etc".

@KarlKastor I used that, but it must be something in Chrome, and I highly doubt it's the printable unprintable characters.

Haskell, 113 bytes

import Data.Time.Clock
f=do t<-getCurrentTime;putStr$"It's "++(fst.span(>'-').show)t++" already, folks, go home."

Try it online! Replace f with main for a full program.

The function getCurrentTime returns a UTCTime object which looks something like "2017-04-02 10:22:29.8550527 UTC" when converted to a string by show. fst.span(>'-') takes the leading characters while they are larger than '-', that is the current year. For the next 7972 years take 4 would work for 8 bytes less, but we want our code to work correctly for ever and ever.

As far as I see build-in functions to get the current year require a import Data.Time.Calendar, so extracting the year from the string should be the shortest option.

"emoh og ,sklof ,ydaerla@ s'tI"4k,y\4*:*/"&2"*+.f7+k,@

Try it online!

Thanks to James Holderness for pointing out my mistake with the sysinfo instruction.

"emoh og ,sklof ,ydaerla@ s'tI" pushes the sentence to the stack where 4k, prints the first word. y is the sysinfo instruction. When passed 20 (the unprintable in the string), it returns 256*256*(year-1900) + 256*month + day of month. \4*:*/"&2"*+. takes just the year from the value and prints it andf7+k, prints the rest of the sentence.


@JamesHolderness Arghhh, that explains why I've never been able to get sysinfo working. Thanks a bunch!
