require 'chilkat'

json = Chilkat::CkJsonObject.new()

jsonStr = "{ \"id\": 1, \"name\": \"A green door\", \"tags\": [\"home\", \"green\"], \"price\": 125 }"

success = json.Load(jsonStr)
if (success != true)
    print json.lastErrorText() + "\n";
    exit
end

numMembers = json.get_Size()

for i in 0 .. numMembers - 1

    name = json.nameAt(i)
    value = json.stringAt(i)

    print name + ": " + value + "\n";

    iValue = json.IntAt(i)
    print name + " as integer: " + iValue.to_s() + "\n";

end

# Note: The StringAt method returns the value as a string regardless of the type.
# If the value is a JSON array (such as for ["home", "green"]), then the JSON encoding
# of the entire array is returned.

# The IntAt method returns the value as an integer.  If the value does not convert to 
# an integer, then 0 is returned
