The sea in your terminal

Question

Background

Summer is well over in the Northern Hemisphere, and a lot of us miss the sun, the beaches, the waves of the ocean... This challenge aims at cheering them up by reminding them of the sea.

The challenge

Here is the sea :

             **              **              **              **              ** 
         ****            ****            ****            ****            ****   
      *****           *****           *****           *****           *****     
    **   **         **   **         **   **         **   **         **   **     
  **      **      **      **      **      **      **      **      **      **    
**          ******          ******          ******          ******          ****

The sea is made of 5 times this wave pattern :

            **  
        ****    
     *****      
   **   **      
 **      **     
*          *****

Note that the pattern is 16 characters long, and the sea is 5 times this pattern = 80 characters long.

Which you can print into a terminal using this command-line :

perl -e 'print "            **  \n        ****    \n     *****      \n   **   **      \n **      **     \n*          *****\n"'

Or this one :

perl -e 'print " "x12, "*"x2, " "x2, "\n", " "x8, "*"x4, " "x4, "\n", " "x5, "*"x5, " "x6, "\n", " "x3, "*"x2, " "x3, "*"x2, " "x6, "\n", " "x1, "*"x2, " "x6, "*"x2, " "x5, "\n", "*"x1, " "x10, "*"x5, "\n"'

(The second one should make it easier for you to get the exact pattern)

Your task is to display the sea in a terminal, and make look like the waves are moving toward the right : it needs to shift to the right at a speed of 1 character each 100ms (= 10 times each seconds). No character should be printed after the 80th column, but as the rightmost wave disappears, a new one appears on the left.
Here is an example of output :

time = 0.0s

             **              **              **              **              ** 
         ****            ****            ****            ****            ****   
      *****           *****           *****           *****           *****     
    **   **         **   **         **   **         **   **         **   **     
  **      **      **      **      **      **      **      **      **      **    
**          ******          ******          ******          ******          ****

time = 0.1s

              **              **              **              **              **

       *****           *****           *****           *****           *****    
     **   **         **   **         **   **         **   **         **   **    
   **      **      **      **      **      **      **      **      **      **

time = 0.2s

*****          ******          ******          ******          ******          *

time = 0.4s

 **              **              **              **              **             
*            ****            ****            ****            ****            ***
          *****           *****           *****           *****           ***** 
        **   **         **   **         **   **         **   **         **   ** 
      **      **      **      **      **      **      **      **      **      **
******          ******          ******          ******          ******          

Of course, each output should replace the previous one.

You can run this code into a unix terminal to see how it should look with the animation:

perl -M5.010 -MTime::HiRes=sleep -E '@arr=([($")x12,($n="*")x2,($")x3],[($")x8,($n)x4,($")x4],[($")x5,($n)x5,($")x6],[($")x3,($n)x2,($")x3,($n)x2,($")x6],[($")x1,($n)x2,($")x6,($n)x2,($")x5],[($n)x1,($")x10,($n)x5]);while(++$j){for$i(0..5){for$k(0..15) {$out[$i][16*$_+$k]=$arr[$i][($k-$j)%16]for 0..4}}say"\e[H",$/,join$/,map{join"",@$_}@out;sleep 0.1}'

(Note that this code isn't very well golfed: I just made it compact enough to be convenient to run in a terminal.)

Winning criterion

This is codegolf, so shortest code in byte wins.

Answer 1

MATL, 41 40 bytes

`'3SJp/B@Tc`@+ara'F'* 'Za6el&Xx80:@-Z)DT

Example run:

Or try it at MATL Online! (the actual speed may depend on server load).

How it works

`                    % Do...while
  '3SJp/B@Tc`@+ara'  %   Compressed string (actually it's just a change of base)
  F                  %   Push false. Indicates base-95 input alphabet for decompression
  '* '               %   Push this string, which defines output alphabet
  Za                 %   Base conversion. This decompresses the string
  6e                 %   Reshape as a 6-row char array. This gives the basic pattern
  l&Xx               %   Pause 0.1 seconds and clear screen
  80:                %   Push array [1 2 ... 80] 
  @-                 %   Subtract iteration index to each element of that array. This
                     %    will produce the rotation via modular indexing
  Z)                 %   Use as column index. Indexing is modular, so this repeats
                     %   (and rotates) the pattern
  D                  %   Display
  T                  %   True. Loop condition for infinite loop
                     % Implicit end

Answer 2

JavaScript (ES6) + HTML, 151 143 + 10 = 161 153 bytes

a=[48,15,57347,6147,1542,504];setInterval("a=a.map(n=>{for(x=-1;++x<80;)s+=' *'[n>>x%16&1];s+=`\n`;return n>>>15|n<<1},s='');O.innerHTML=s",99)

<pre id=O>

Answer 3

HTML + CSS, 70 + 181 175 = 245 bytes

Makes use of text-shadow, rtl text and CSS keyframe animations.

a{display:flex;overflow:hidden;width:80ch}pre{text-shadow:16ch 0,32ch 0,48ch 0,64ch 0,80ch 0;direction:rtl;animation:w steps(16)1.6s infinite}@keyframes w{0%{margin-left:-16ch

C# 450 444 425 417 Bytes

399 without using System.Linq; but I'm sure that would be cheating...

Edit: Saved 25 Bytes thanks to @Cyoce

Golfed:

Edit

1. Used y$ instead of <C-v>$y

2. A lot of changes

   • Instead of copying each line and pasting them 4 times, I first generate the wave and then copy the whole thing and paste it 4 times
   • Used { and } to save few bytes
   • Used ò instead of registers to create the infinite loop (for some reason I have to include a ò at the end for it to work)
   • fixed the static * at the bottom

Mini-Explanation

I'm using <alt-n> to create copies of strings. For example, <alt-5>* (this looks like µ5) makes 5 copies of * in insert mode. This I found to be shorter than copying the string and using a regex to do the necessary replacements. After creating one wave, I paste it to create the other waves. Finally, I loop recursively using ò to create the infinite loop (with a delay of 100ms).

Gif

Most of the code is dedicated towards creating the wave, so I'm still trying to golf this. Note that this code will not work on TIO since TIO only outputs the output after the code has finished execution. So here's a gif (sorry for the low quality, I had to use a website to convert a .mov to a .gif, also the >_ that keeps popping up in the right is the Terminal icon on my mac's dock):

Some lines have trailing spaces. Requires a standard 80-column terminal. The timing isn't very accurate, but it's the best you can do in Batch.

Then, the loop slides an 80-bytes-wide window through that pattern.

ol?!R

^{Note: "H;0[" is supposed to have ascii 27 after [.}

Try it here! (set delay to 0ms)

I can't believe I ended up sucessfully making this. This uses the I and D instructions, which increments or decrements the selected stack. This is demonstrates that it's probably possible to do this in pure ><> (minus the sleep) or a competetive *><> answer, though probably a lot harder to do.

The online interpreter version is different simply to clear the output using a carriage return.

This is non-competing because the I, D, C, and R instructions are younger than the challenge. This is probably possible to do without those instructions, but it'd be very hard/long.

Edit: I actually managed to remove a byte, but I also noticed I measured the size wrong, so I actually gained a byte.

I'll do my best to break down the steps and explain what's happening here...

Initialization

Here we build the 6 lines which construct the waves. We need to repeat each string 5 times to be the correct length.

We start with 6 of these, one for each line of the wave:

 " **             "       push " **             " to the stack

                      0[  create a new stack

And we enter the main loop after initialization through 09..

Copy Current Stack 4 Times

This is a simple function which simply takes the current stack, and copies it 4 times. So "a" would become "aaaaa".

54C              call "copy stack"
   l2,[          copy half the current stack to a new stack
       54C54C    call "copy stack" twice
             ]   close the current stack, moving values to the one below
              R  return from the function

Copy Stack

This copies the current stack, appending the copy to the current stack.

Setup

Going to skip the initial < and invert the first line to become l:&0v as that's the order it gets executed in after the < changes the IP's direction.

l      push the stack length to the stack
 :&    copy the length to the register
   0   push 0 to the stack
    v  move the IP downwards, entering the loop

From here on out the length will be referred to as n and the 0 as i.

Loop

>                        move the IP to the right
 :                       copy i
  @=?v                   pop i from the stack, if n == i, proceed to cleanup
      1+                 add 1 to i
        {:}              copy the first value of the stack to the end of the stack
           &             place n on the stack
            l1-[         open a new stack moving all values but index 0 to the new one
                :&       copy n and place it on the register
                  $@     swap i with the value on its right
                     $   swap i with n

Cleanup

>                        move the IP to the right
 :?!v                    if i == 0 then ...
  ~R>                      remove i from the stack and return
     ]                   close the stack, appending all values to the stack below
      1-                 subtract 1 from i

Main Loop

Here is where the code runs forever, constantly redrawing the waves in-between 100ms sleeps.

Setup

DDDDDD                 select the 6th stack down
      "H;0[x"ooooo     move the cursor to the top-left of the term (x == ascii 27)
                  v    move the IP downwards, entering the loop 

Loop

>                          move the IP to the right
 l?u     O                 if the stack is empty ...
    1S                       sleep for 100ms
      09.                    jump to main loop initialisation
          {                shift the stack left
           54Cl2,[         copy the current stack to a new stack
                  a        append a newline to the stack
                   }       shift the stack to the right
                    4cC    call "output stack"
                       ]   close the stack
                        I  select one stack higher

I don't see any way of golfing the wave pattern in Mathematica other than just starting with a list of strings for each line. I initialize i to be 0 and schedule a task to increment it every 0.1 seconds. I Dynamically display the result of the following:

1. StringRepeat each line 5 times.
2. Convert each line into a list of its Characters.
3. RotateRight each list of characters by i.
4. Display the resulting array of characters as a Grid.

Explanation

A fairly straightforward solution that stores the wave as a string at the beginning, which is unpacked to binary, each section is quintuplicated, 0s are converted to spaces and 1s are converted to *s. Now we have the whole string so we enter a redo loop which prints out the whole string, then we wait for .1 seconds and for each line in the string, we move the last character to the beginning of the string.

Answer 22

Mathematica 171 Bytes

The wave itself is data, so I'm storing a compressed version of the whole wave in my code. I can store a single wave much more compactly as \fð߀ᣀ恠耟 using it's binary representation, but the character count overhead of uncompressing is too high*.

Here is the code:

w=Uncompress@"1:eJxTTMoPSmNjYGAoZgESPpnFJcEBQIYCEtDSUlCglI9iqJYWqhJy+QhDtdCUUMCHGQrmIymiiA8xFMajEg02FMkXWmi+IosPAJNuSHg=";
Dynamic[Pause[.1];Column[w=StringRotateRight/@w]]   

Here is the code I used to create the compressed version of the wave data:

s={"            **  ","        ****    ","     *****      ","   **   **      "," **      **     ","*          *****"};
s//TableForm
StringRepeat[#,5]&/@s
Compress[%]

Here is the code I would have preferred to use to store compressed repeating binary data like this wave:

StringJoin /@ (PadLeft[(IntegerDigits[#1, 2] & ) /@ ToCharacterCode["\fð߀ᣀ恠耟"]] /. {0 -> " ", 1 -> "*"})

As you can see, the overhead to turn the compressed data back into a string is too expensive for this particular problem, although a single wave can be stored this way with 7 UTF characters and 15 bytes.

Here was the code to determine the UTF character sequence to store a single wave (s as above).

StringReplace[#,{" "->"0","*"->"1"}]&/@s
ToExpression/@%
IntegerDigits/@%
FromDigits[#,2]&/@%
FromCharacterCode/@%
StringJoin@%
