Demonstrates renaming and deleting members. This example uses the following JSON document:

{
   "apple": "red",
   "lime": "green",
   "banana": "yellow",
   "broccoli": "green",
   "strawberry": "red"
}

require 'chilkat'

json = Chilkat::CkJsonObject.new()

success = json.Load("{\"apple\": \"red\",\"lime\": \"green\",\"banana\": \"yellow\",\"broccoli\": \"green\",\"strawberry\": \"red\"}")
if (success != true)
    print json.lastErrorText() + "\n";
    exit
end

# Rename "lime" to "lemon".
success = json.Rename("lime","lemon")
# Change the color to yellow:
success = json.SetStringOf("lemon","yellow")

# Rename by index.  Banana is at index 2 (apple is at index 0)
success = json.RenameAt(2,"bartlett_pear")

# Delete broccoli by name
success = json.Delete("broccoli")

# Delete apple by index.  Apple is at index 0.
success = json.DeleteAt(0)

json.put_EmitCompact(false)
print json.emit() + "\n";
