This directory contains example code that uses Protocol Buffers to manage an address book. Two programs are provided, each with three different implementations, one written in each of C++, Java, and Python. The add_person example adds a new person to an address book, prompting the user to input the person's information. The list_people example lists people already in the address book. The examples use the exact same format in all three languages, so you can, for example, use add_person_java to create an address book and then use list_people_python to read it. You must install the protobuf package before you can build these. To build all the examples (on a unix-like system), simply run "make". This creates the following executable files in the current directory: add_person_cpp list_people_cpp add_person_java list_people_java add_person_python list_people_python If you only want to compile examples in one language, use "make cpp"*, "make java", or "make python". All of these programs simply take an address book file as their parameter. The add_person programs will create the file if it doesn't already exist. These examples are part of the Protocol Buffers tutorial, located at: https://developers.google.com/protocol-buffers/docs/tutorials * Note that on some platforms you may have to edit the Makefile and remove "-lpthread" from the linker commands (perhaps replacing it with something else). We didn't do this automatically because we wanted to keep the example simple.
