An example post about code insertion into posts.

## Testing code snippet highlight

The following example shows how to highlight a piece of code throughout the use of pygments:

class Singleton(type):
    """Base metaclass for Singleton pattern
@see http://stackoverflow.com/a/6798042/1977778
    _instances = {}
    def __call__(cls, *args, **kwargs):
        if cls not in cls._instances:
            cls._instances[cls] = super(Singleton, cls).__call__(*args, **kwargs)
        # If you want to run __init__ every time the class is called, add the following else condition
        # else:
        # cls._instances[cls].__init__(*args, **kwargs)
        return cls._instances[cls]

Code highlighting with redcarpet

Another snippet rendered with the most common Github code syntax:

``` python def strip_nonascii(self, s): “"”This method remove non-ascii chars from argument””” return ud.normalize(‘NFKD’, unicode(s) ).encode(‘ascii’,’ignore’)

def create_users_table(self, cursor):

    """ Check the existence of the users log table, otherwise create it """

    pass ```

``` scala

package astrac.akka.askretry

import akka.actor._ import akka.util.Timeout import akka.pattern.ask import scala.concurrent.duration._ import scala.concurrent.Future

object RetryingActor { case class AskT case object Retry

  case class RetryException(attempts: Int) extends Exception(s"Cannot retry
  after $attempts attempts")
    def props[T] = Props[RetryingActor]
    } ```
