Output the legendary Yggdrasil

Question

Your task is to output a representation of the legendary tree of life, Yggdrasil.

You must write a program whose output is exactly that :

                                       /\
                                      /**\

There is no trailing whitespace. The final newline may be omitted.

To make checking easier, here are the md5 sums of the expected output:

• 374899e56bc854d04639c43120642e37 - No newline at end.
• 03afb81d960b8e130fe2f9e0906f0482 - Newline at end

Standard loopholes apply. This is code-golf, so the smallest entry in bytes win!

Answer 1

Haml & Sass

37 + 277 = 314

Haml:

%link(rel="stylesheet" href="s")
%pre

Sass:

pre:after{$l:"";@for$k from0 to10{@for$i from0 to4+$k{@for$j from0 to40-($k*6+$i*2)/2{$l:$l+' ';}$l:$l+'/';@for$j from0 to$k*6+$i*2{$l:$l+'*';}$l:$l+"\\\a ";}}@for$i from0 to12{@for$j from0 to35{$l:$l+" ";}@if$i<11{$l:$l+"|--------|\a ";}@else{$l:$l+"|________|";}}content:$l;}

*Sass allows control directives, concatenation, and variable dereference. All of which are useful when styling, but verbose while golfing.

Thanks to Howard for saving 3 characters!

Explanation:

This is more or less a straightforward port of my Python solution. Taking some expressive liberties (using named variables instead of keeping track of stack positions, and print is really keeping things on the stack, not printing):

10,{...}/            # for i in range(10):
   .                 #    x = i
   )4*,              #    Y = range((i+1)*4)
   \3*               #    x *= 3
   >                 #    Y = Y[x:]  # y is now range(3*i, (i+1)*4)
   {...}/            #    for j in Y:
      .39\-          #        q = 39 - j
      ' '*           #        print ' '*q  # print right number of spaces
      '/'            #        print '/'
      @2*            #        j *= 2
      '*'*           #        print '*'*j
      '\<NEWLINE>'   #        print "\\\n"
12,{...}/            # for i in range(12):
    ' '35*           #    print ' '*35
    '|'              #    print '|'
    @11<             #    i = i < 11
    '_-'1/=          #    z = "_-"[i] # pick "-" if i < 11, else pick "_"
    8*               #    print z*8
    1$               #    print '|' # (copy from earlier in the stack)

Answer 5

Bash, 236 197 193

10 bytes of code + 1-byte filename + 182-byte data file = 193 bytes total

zcat y 2>j

Explanation

y is a file containing the Yggdrasil, without a trailing new line, compressed with the zopfli algorithm (invoked as zopfli --i64) and then with the last 8 bytes removed. zopfli is compatible with gzip, so I can decompress the file with standard Bash utilities designed for gzip. The size of the data file is 182 bytes (229 bytes when normal gzip is used). The size of the original Yggdrasil, without the trailing new line, is 5876 bytes.

The removal of the last 8 bytes causes error messages, which are suppressed by sending standard error to a file called j. If j exists, it will be overwritten.

The base64 of y is (use base64 -d to obtain the original file):

Thanks to some annoymous user for the suggested edits making good use of the String.PadLeft method!

using System;class G{static void Main(){Action<string>p=Console.WriteLine;int i=0,j;for(;i++<10;)for(j=i*3-3;j++<i*4;)p("/".PadLeft(41-j)+"\\".PadLeft(2*j-1,'*'));while(i-->0)p("|--------|".PadLeft(45));p("|________|".PadLeft(45));}}

The code is pretty simple, not much left to golf.

Formatted code:

using System;
class G
{
    static void Main()
    {
        Action<string> p = Console.WriteLine;
        int i = 0, j;
        for(; i++ < 10 ;)
            for(j = i*3 - 3; j++ < i*4;)
                p("/".PadLeft(41 - j) + "\\".PadLeft(2*j - 1,'*'));
        while(i-- > 0)

Answer 19

Haskell, 153 148

Straight-forward, no tricks, just plain golfing:

(a:b:c)%n=(39-n)&' '++a:(2*n)&b++c
n#m=[n..m]++(n+3)#(m+4)
(&)=replicate
main=putStr$unlines$map("/*\\"%)(take 85$0#3)++map("|-|"%)(11&4)++["|_|"%4]

The % operator draws a single line, its first argument being a String of length 3 containing the borders and the fill characters in that line (now assuming exactly 3 Chars, saving 5 bytes), the second, an Int, specifies half the number of fill characters. Pattern matching, cons-ing and appending is used in combination in order to save bytes by taking care of the "glue" between Char and String. In this second version, I also made # infinite and introduced a take 85 to make it finite again (no bytes saved, unfortunately).

The # operator creates the sequence for the n argument to % required for the tree: [0..3], [3..7], ... concatenated.

& is just an infix shorthand for replicate, which occurs three times.

The tree is put together in the last line, the newlines are added by unlines.

    ,

Not counting newlines. Mathematica skews the output, as it doesn't take the same width for a whitespace as for "*" and "/". But the result is correct.

Edit: Saved ~100 bytes by hard coding each character in a register and simply writing to the stack, then abusing the fact that MIPS doesn't have types so implicit word to ascii string is allowed.
Edit 2: removed duplicate stack alloc. (addi $sp -4) Oops!
Edit 3: in rewrite, accidently made the tree stump 1 character too short. (36 in stead of 35). Fixed.
Edit 4: -4 bytes by using $8 and $9 instead of $t0 and $t1. they mean the same thing, but $t0 is easier to read. unfortunately, all other t registers are the same length when written nicely ($t2 == $10, but both are 3 characters), so the rest are a wash. I could (in theory) use the remaining 'a' registers (5-7. print syscall uses 4), but afaik the behavior isn't defined when using syscall.
-1 Byte by setting t8 to 0 and branching on less than instead of on equal. also required me to reorder the add ops, which unfortunately made the execution time take a whopping 3 opcodes longer.

Not the best at MIPS, but after clearing my conscience of this in meta discussion, i'm submitting them. MIPS is not designed for this (no output, no for loops) but it's pretty fun to do this perhaps in spite of that.

Unfortunately, I haven't created a commented version for this new solution, but you can view the old version, with full documentation here
