发点代码

var s = "JavaScript syntax highlighting";
alert(s);

s = "Python syntax highlighting"
print s

require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html

{
  "firstName": "John",
  "lastName": "Smith",
  "age": 25
}

<?php
  echo 111;

#!/bin/bash
#

if [ ! -e ./config.ini ]; then
    echo "config.ini is not exists..please check.."
    exit 1
fi

function () { return "This code is highlighted as Javascript!"}
