I Love Sardines

I love sardines, I can't get enough of them, and so does my computer, the Omnilang 5000, which is language agnostic.

To give my computer the joy of experiencing sardines, I've decided to feed him a number of programs that are capable of displaying on the screen tins of sardines in various orientations, and showing up to ten sardines.

In this challenge, you'll be responsible for creating the programs based on these parameters:

The input

A number (between 0 and 10) and a letter from one of the following "LR" (representing Left or Right respectively) For example: 3L or 5R; how this is input into the program is up to you.


An open tin of sardines with the sardines facing the indicated direction, with the key (represented by the "%" character) and peeled lid (rolled up tin at the end represented by the "@" character) located at the top of the tin.

  • All sardines must face the direction indicated by the input.
  • All sardines will have bodies five characters long between the gill (either ")" or "(" ) and the tail "><"
  • The key and peeled lid roll will always be facing the opposite direction to the sardines.
  • The tin must have a 3-D look to it as shown below in the examples.
  • The minimum height of the tin is 3 sardines in height. So if a number is less than 3, a tin of 3 sardines in height must be shown, with the inputted number of sardines in it. Otherwise, the tin must be the number of sardines high indicated in the input. So input of 0R or 0L will show an empty sardine tin.
  • Any other input that can't be validated will not show anything.

For example, for "3L"


For "7R"


For "2L"

|          ||

For "0R"

 ||          |
 ||          |
 ||          |


|          ||
|          ||
|          ||

Invalid input will not return anything...

  • This is code golf, so the smallest number of characters will win this challenge.
  • No Loopholes as per usual.

Try it online, or watch it at the fish playground! Reads the "L" or "R" from STDIN and assumes the number of sardines is already on the stack (needs a -v flag for +3 bytes).

Because of course I had to write this in ><>.

How does the fish playground work? I can't get it to run. Where do I place the input?
Not a tree 07/31/2017
@JarkoDubbeldam, after copying the code into the window and submitting it, you need to put the number of sardines where it says "initial stack" (simulating the -v flag), and the direction ("L" or "R") under "give input to the program" then click "give". (I've edited the answer to hopefully make that clearer.)

@officialaimm intrestingly enough, if supplied with a negative value, it extends the size of the tin, but doesn't put sardines in.
3 officialaimm 07/30/2017
@Phoenix Yes. It doesn't matter though, since OP has specified the range 0 to 10 . P.S.` -10` would print empty tin, becuase it signifies that there were 10 sardines, but you already ate them. :D

Fishing isn't on Try It Online, but there's an interpreter for it in Ruby on the linked esolangs page.

This is the first program I've made in Fishing -- in fact, it's the first program I've made in any 2D language -- so it can probably be a lot shorter. Golfing tips are welcome (though I wouldn't be surprised if no one gave any, considering that even I don't know what the heck I just wrote).

Here's a GIF of the path the program takes for input 1R (sorry for low quality):

Input is a comma separated tuple of numbers of this format: 2, 1. The first number is the amount of fish and the second is is 0 for left and 1 for right.

This started out as an attempt to out-golf the other answer (I totally thought I could), but it sucks. :P If anybody can make head and tail of it and help golf it (I blame it on it being 12 am right now), I'd be glad.

Takes an integer and a char (L, R) as parameters and outputs the resulting string.

Ugh. Had to deal with some annoying string constants, sadly you cant just do string * length in C#. And the method with new string(char, length) wouldn't have been worth the byte cost.

The algorithm works as follows:

  1. At the start we determine if the sardines face right or left, since we will then format our strings accordingly. We create a string for the top, with some conditional operators to switch between the L and R perspective.
  2. Then we create a loop that runs 3 times at minimum and the left input times at maximum. That way we can create empty spaces if we have less than 3 sardines in our box.
  3. Inside this loop we format a string, depending on the perspective and also, if h > i, we put a sardine inside of it. If i >= h, there will be an empty space where a sardine would normally be.
  4. At the end we create the bottom of the box, again formatted according to perspective.

1 Jared Smith 07/31/2017
@WallyWest I use the _ function twice, once for the 10 underscores (which gets used twice), once for the 10 equal signs, so having it in a function saves me a byte. And unless I'm using template strings wrong, using them instead of concatenation is 3 bytes more.
