Syntax highlighting

This theme supports syntax respectively code highlighting. Below you find some examples of different programming languages.

ruby:

def foo
  puts 'foo'
end

def bubble_sort(list)
  return list if list.size <= 1 # already sorted
  swapped = true
  while swapped do
    swapped = false
    0.upto(list.size-2) do |i|
      if list[i] > list[i+1]
        list[i], list[i+1] = list[i+1], list[i] # swap values
        swapped = true
      end
    end
  end

  list
end

python:

def func():
     # function body
     print("hello world!")

     def setup(app):
         # enable Pygments json lexer
         try:
             import pygments
             if pygments.__version__ >= '1.5':
                 # use JSON lexer included in recent versions of Pygments
                 from pygments.lexers import JsonLexer
             else:
                 # use JSON lexer from pygments-json if installed
                 from pygson.json_lexer import JSONLexer as JsonLexer
         except ImportError:
             pass  # not fatal if we have old (or no) Pygments and no pygments-json
         else:
             app.add_lexer('json', JsonLexer())

         return {"parallel_read_safe": True}

words = ['cat', 'window', 'defenestrate']
for w in words:
   print w, len(w)

php:

<?php function add($x, $y) {
    $total = $x + $y;
    return $total;
}
echo "1 + 16 = " . add(1, 16);
?>

js:

function sayHello(name) {
  if (!name) {
    console.log('Hello World');
  } else {
    console.log(`Hello ${name}`);
  }  
}  

function myFunc(a, b) {
    return a * b;
}
document.getElementById('demo').innerHTML = myFunc(4, 3);

java:

class HelloWorldApp {
    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

objective c:

- (int)method:(int)i {
    return [self square_root:i];
}

perl:

while (<>) {
    chomp;
    if (s/$//) {
        $_ .= <>;
        redo unless eof();
    }
}

sql:

SELECT Country FROM Customers WHERE Country <> 'USA'

c++:

#include
using namespace std;
int main () {
  cout << "Hello World!";
  return 0;
}

c sharp:

class Foo {
    public int Value;
    public static explicit operator Foo(int value) {
        return new Foo(value);
    }
}
Foo foo = (Foo)2;

vb:

Private Sub Form_Load()
    MsgBox "Hello, World!"
End Sub
