Christmas quine!

Question

In the language of your choice, write a program that is arranged in the shape of a Christmas tree that prints itself in the same shape.

What is not allowed:

• Printing out the source file
• Code that is nothing but statements that get echoed by an interpreter by virtue of them being literals (eg just using a tree-shaped tower of lists in python)

Answer 1

JavaScript

The 'star' might be a bit too large for the tree...

        (function _()
     {return('        (')
      +(''+''+''+''+'')
             +_+
            ')()'
           ;'We w'
          +'wis'+0+
         'h you a '
        +0+'merry Ch'
       +'ristmas, '+0+
      +'we '+0+'wish y'
     +0+'ou a merry Chr'
    +'istmas, we w'+0+'i'
   +0+'sh you '+0+'a merr'
  +'y Christmas and a h'+0+
 +'appy'+0+'new year! Ho ho'
+0+' ho! Merry '+0+'Christma'
            +'s!'
            })()

The zeroes are baubles and look best in the editor:

Answer 2

Ruby

You never said we couldn't use network access... :D

        #
       s="
      open(
     'http:/
    /pastebin
   .com/raw.ph
  p?i=mGzbahp5'
 ).read";s=eval(
s.gsub! /\s/,'');
      puts(
      s+'')

Outputs itself verbatim.

Yes, I could have used a URL shortener, but that would have made it less obvious and amusing :P Also I needed something to take up space; otherwise the tree would be tiny.

Execute like this:

ruby -ropen-uri christmasquine.rb

Answer 3

perl

#!/usr/bin/perl
$_=<<'the source';eval $_;

          #
         #*#
        print
       "#!/u".
      "sr/bin".
     "/perl \n".
    "\$_=<<'the".
   " source';eva".
  "l \$_;\n${_}th".
 "e source\n";# Mery 
#Christmas to all !!!
         ###
         ###
         #*#

the source

Answer 4

Here's a tiny one in GolfScript:

   {
  ".~  
 "2/~\
+@@2$*}.
   ~

Note that the code above includes two space characters at the end of the second line from the top; those spaces are essential for correct operation. Also, the code should be saved using Unix-style (LF) linefeeds, not Windows-style CR+LF.

---

Here's a slightly bigger (and less whitespace-sensitive) one, including a festive message:

     {
    " "
   MERRY
  5*n\+\n
 CHRISTMAS
".~"+2$*1>}
     .
     ~

A mildly interesting feature is that the words MERRY and CHRISTMAS are not string literals, although they are no-ops, and are copied to the output along with the code block surrounding them.
