1+
This directory contains example code that uses Protocol Buffers to manage an
2+
address book. Two programs are provided, each with three different
3+
implementations, one written in each of C++, Java, and Python. The add_person
4+
example adds a new person to an address book, prompting the user to input
5+
the person's information. The list_people example lists people already in the
6+
address book. The examples use the exact same format in all three languages,
7+
so you can, for example, use add_person_java to create an address book and then
8+
use list_people_python to read it.
9+
10+
You must install the protobuf package before you can build these.
11+
12+
To build all the examples (on a unix-like system), simply run "make". This
13+
creates the following executable files in the current directory:
14+
add_person_cpp list_people_cpp
15+
add_person_java list_people_java
16+
add_person_python list_people_python
17+
18+
If you only want to compile examples in one language, use "make cpp"*,
19+
"make java", or "make python".
20+
21+
All of these programs simply take an address book file as their parameter.
22+
The add_person programs will create the file if it doesn't already exist.
23+
24+
These examples are part of the Protocol Buffers tutorial, located at:
25+
https://developers.google.com/protocol-buffers/docs/tutorials
26+
27+
* Note that on some platforms you may have to edit the Makefile and remove
28+
"-lpthread" from the linker commands (perhaps replacing it with something else).
29+
We didn't do this automatically because we wanted to keep the example simple.
30+
31+
## Go ##
32+
33+
The Go example requires a plugin to the protocol buffer compiler, so it is not
34+
build with all the other examples. See:
35+
https://github.com/golang/protobuf
36+
for more information about Go protocol buffer support.
37+
38+
First, install the Protocol Buffers compiler (protoc).
39+
Then, install the Go Protocol Buffers plugin
40+
($GOPATH/bin must be in your $PATH for protoc to find it):
41+
go get github.com/golang/protobuf/protoc-gen-go
42+
43+
Build the Go samples in this directory with "make go". This creates the
44+
following executable files in the current directory:
45+
add_person_go list_people_go
46+
To run the example:
47+
./add_person_go addressbook.data
48+
to add a person to the protocol buffer encoded file addressbook.data. The file
49+
is created if it does not exist. To view the data, run:
50+
./list_people_go addressbook.data
51+
52+
Observe that the C++, Python, and Java examples in this directory run in a
53+
similar way and can view/modify files created by the Go example and vice
54+
versa.
