write a code snippet to print itself

js.js

// JS:
(function(){console.log('(' + arguments.callee.toString() + ')()')})();


// JS, recursion
~function (){
    typeof i !== 'number' && (i = 0);
    return (i++ < 3) &&
        (fn = '~' + arguments.callee.toString() + '()') && 
        (console.log(fn), eval(fn));
}();

C:

char*s="char*s=%c%s%c;main(){printf(s,34,s,34);}";
main(){printf(s,34,s,34);}

#define q(k)main(){return!puts(#k"\nq("#k")");}
q(#define q(k)main(){return!puts(#k"\nq("#k")");})

Python:

a = "print 'a = ', repr(a), '\n', repr(a)[1:-5]', a"
print 'a = ', repr(a), '\n', repr(a)[1:-5]

a = ["print 'a = ', a, '\\n', ''.join(a)"]
print 'a = ', a, '\n', ''.join(a)

Java:

class S{public static void main(String[]a){String s="class S{public static void main(String[]a){String s=;char c=34;System.out.println(s.substring(0,52)+c+s+c+s.substring(52));}}";char c=34;System.out.println(s.substring(0,52)+c+s+c+s.substring(52));}}

<?php $s='<?php $s="%s"; echo sprintf("\'".$s."\'", $s);?>'; echo sprintf("\'".$s."\'", $s);?>
