Pizza, Pizza, Deep Dish Pizza!

Question

April 5th is National Deep DIsh Pizza Day, the theme of this challenge. Given a positive integer n (n is greater than 0), create an ASCII deep dish pizza. Actual deep dish pizza shown:

As you can see, there is a layer of crust on the bottom and surrounding the rest of the pizza.

How to make the pizza

The crust is made of two layers. The first layer will be n tall and n*3 long. Length is the number of characters (including spaces) in the highest line. So given n is 1, the first layer would look like this:

\_/  1 character tall
 3 characters long

If n is two:

\    /   2 characters tall
 \__/
  6 characters long

Now for the second layer of the crust. It will go outside the first, inner crust so therefore, it will be n+2 characters tall and (n*3)+6) characters long. Given n is one:

\       /  3 characters tall
 \     /
  \___/
   9 characters long (3 underscores, 3 slashes on either side)

If n is two:

\          / 4 characters high
 \        /
  \      /
   \____/
    12 characters long

You would then match up the two highest pairs of \/ with each other for the inner and outer crust. In n is 1:

\ \   / /
 \ \_/ /
  \___/

If done correctly, it would look like a V without the tops with a one character difference between each layer. Speaking of tops, the crust will be joined together by a pair of /\, separated by a line of underscores (n*3)+2 long to complete the crust and pizza.

Examples

If n is 1:

/\_____/\
\ \   / /
 \ \_/ /
  \___/

n is 2:

/\________/\
\ \      / /
 \ \    / /
  \ \__/ /
   \____/ 

n is 3:

/\___________/\
\ \         / /
 \ \       / /
  \ \     / /
   \ \___/ /
    \_____/

Winning Criterion

This is code-golf, so the shortest code in bytes wins!

Answer 1

JavaScript (ES6), 136 bytes

f=
n=>"/\\"+(r=s=>s[0][0].repeat(n-1)+s)`_`+r`_`+r`___/\\
`+r` `.replace(/ /g,"$`\\ \\$`   $'$'$'/ /\n")+r` \\ \\`+r`_/ /
`+r`  \\`+r`___/`

<input type=number min=1 oninput=o.textContent=f(this.value)><pre id=o>

The whole pizza is very repetitious so the r function (designed as a tagged template literal) repeats the first character of its input n times. This handles the top and bottom two lines of the pizza. The middle is repeated by replacing a string of blanks; the $` and $' subsitutions automatically correspond to increasing and decreasing numbers of blanks thus positioning the \ \ and / / appropriately.

(Lazy-ish attempt)

function t(n);p=@(q)fprintf(q);s=@(x)p(' ');r=@()p('/ /');l=@()p('\\ \\');f=@()p('/');b=@()p('\\');u=@(x)p('_');h=@()p('/\\');e=@()p('\n');h();arrayfun(u,1:3*n+2);h();e();for i=1:n;arrayfun(s,1:i-1);l();arrayfun(s,1:3*n-2*(i-1));r();e();end;arrayfun(s,1:n);l();arrayfun(u,1:n);r();e();arrayfun(s,1:n+1);b();arrayfun(u,1:n+2);f();e();

Formatted:

function d(n)
p=@(q)fprintf(q);
s=@(x)p(' ');
r=@()p('/ /');
l=@()p('\\ \\');
f=@()p('/');
b=@()p('\\');
u=@(x)p('_');
h=@()p('/\\');
e=@()p('\n');
h();arrayfun(u,1:3*n+2);h();e();
for i=1:n
arrayfun(s,1:i-1); l(); arrayfun(s,1:3*n-2*(i-1)); r();e();
end
arrayfun(s,1:n); l(); arrayfun(u,1:n); r();e();
arrayfun(s,1:n+1); b(); arrayfun(u,1:n+2); f();e();

Basic idea is I have function handles to print everything, and then I just pretty much brute-force it. The one for loop is for the n layers between the very top and the bottom of the inside layer. The repetition of (spaces) and _ is done using arrayfun, with array inputs. Will try to think of more interesting ways to do this if I get more time later.

This is my first ascii-art post!

Add a f= at the beginning and invoke like f(arg).

n=>{a=[];w=" ";u="_";t=`/\\${u.repeat(n*3+2)}/\\
`;for(i=0;i<n+1;i++){c=i==n?u:w;a.push(`${w.repeat(i)}\\ \\${c.repeat((n+1-i*2)+n+(n-1))}/ /
`)};return [t,...a,`${w.repeat(i)}\\${u.repeat(n+2)}/`].join``}

Note: All line breaks are necessary!

f=n=>{a=[];w=" ";u="_";t=`/\\${u.repeat(n*3+2)}/\\
`;for(i=0;i<n+1;i++){c=i==n?u:w;a.push(`${w.repeat(i)}\\ \\${c.repeat((n+1-i*2)+n+(n-1))}/ /
`)};return [t,...a,`${w.repeat(i)}\\${u.repeat(n+2)}/`].join``}

document.querySelector("#elem").innerHTML = f(+prompt("Enter a Number"));

<pre id="elem">

Explanation

The code first declares an Array a. It then declares w and u having the value of whitespace and underscore respectively. Then, it declares a String variable to hold the value of the crust (which can be computed by /\+(n*3+2 underscores)+/\, as mentioned in the Challenge). After that, with a for loop and a Template Literal, the middle of the pizza is created (with each layer having i whitespaces at the starting and (n+1-i*2)+n+(n-1) whitespaces between \ \ and / /, where i represents the index of for loop). At the last, the bottom most part of the pizza is created ((i whitespaces)+\+(n+2 underscores)+/). All parts are joined together and output(ted).

@set l=@for /l %%i in (1,1,%1)do @call 
@set t=
@set s=

@echo /\_%s%_/\
%l%echo %%t%%\ \%%s:_= %%/ /&call set t= %%t%%&call set s=%%s:~2%%
@echo %t%\ \%s%/ /
@echo %t% \_%s%_/

t contains the left indent while s contains the inside; its _s are subsituted with spaces on the middle rows. l just exists to avoid some repetition.

Pretty Code:

    l = n*3+6;
    char u[l];

    // Initialize u[] with a full line of underscores,
    for (i=0;i<l;)
        u[i++] = '_';

    // Make sure the string ends in a valid way
    u[l] = i = 0;

    /* Print the crust 'top'
     * l-4 dashes are needed because '/\/\'
     * %.*s notation to pad (l-4) bytes of the underscore string
     */
    printf("/\\%.*s/\\\n", l-4,u);

    /* Print n rows of just 'walls' \ \  / /
     * each row has i=0++ leading spaces,
     * and each row has n*3-(2i) center spaces
     */
    for(; i<n; i++)
        printf("%*s\\ \\%*.s/ /\n", i,"", n*3-(2*i), "");

    /* Print i spaces, '\ \', n underlines, '/ /'

     */
    printf("%*.s\\ \\%.*s/ /\n%*.s\\%.*s/\n",i,"",n,u,i+1,"",n+2,u);

Edits:

• removed s[l] and associated by switching from %.s notation to %.s
• added function wrapper for compliance & try it online

Way too long. I'm going to try another approach.

"/\\"ri:M3*:A2+'_*1$NL{"\ \\"AS*"/ /"3$S+A((:A;N\}M*4$A'_*4$N4$S'\A2+'_*'/

Builds the string line-by line. Nothing too crazy.

Well, this is actually longer than my other solution at the moment, but I think it's more golfable:
