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.
|
||
|
|
||
|
## Go ##
|
||
|
|
||
|
The Go example requires a plugin to the protocol buffer compiler, so it is not
|
||
|
build with all the other examples. See:
|
||
|
https://github.com/golang/protobuf
|
||
|
for more information about Go protocol buffer support.
|
||
|
|
||
|
First, install the Protocol Buffers compiler (protoc).
|
||
|
Then, install the Go Protocol Buffers plugin
|
||
|
($GOPATH/bin must be in your $PATH for protoc to find it):
|
||
|
go get github.com/golang/protobuf/protoc-gen-go
|
||
|
|
||
|
Build the Go samples in this directory with "make go". This creates the
|
||
|
following executable files in the current directory:
|
||
|
add_person_go list_people_go
|
||
|
To run the example:
|
||
|
./add_person_go addressbook.data
|
||
|
to add a person to the protocol buffer encoded file addressbook.data. The file
|
||
|
is created if it does not exist. To view the data, run:
|
||
|
./list_people_go addressbook.data
|
||
|
|
||
|
Observe that the C++, Python, and Java examples in this directory run in a
|
||
|
similar way and can view/modify files created by the Go example and vice
|
||
|
versa.
