ofxProtobuf is a Google's Protocol buffers addon for openFrameworks

CAUTION

this addon is working-in-progress. let me work a little bit more...

About this addon

for now this is a simple addon supports an use of protocol buffer for openFrameworks projects. it currently supports only OSX (10.13~), however, you can put other compiled library(ies) so that this addon can supports other platforms too!

Protobuf: 3.12.3 oF: 0.11.0 (osx) Platform: MacOSX 10.13~10.15

Difference from the original protobuf

• Edited file name of <google/protobuf/stubs/time.h> to <google/protobuf/stubs/protobuf-time.h> due to the conflict with <ctime>

HOW TO USE

Create a project with projectGenerator and open src directory with a console pp (i.e. Terminal.app / iTerm in OSX). Once you create a .proto file based on the protobuf notation in the directory, you can compile the file to generate .h file and .cpp file by following command:

(OSX)
(path_to_OF_addons_directory)/ofxProtobuf/bin/osx/protoc your.proto --cpp_out=./

After that, you can load both of the header file and cpp file into the project so that you can use the protocol buffer in your OF project!

Use Protobuf with networking

Easiest method will be encoding your protobuf class data into a string then send it over networking, such as OSC, UDP, TCP, ZeroMQ. (more examples will be coming soon!)

TDL

• OF-style wrapper
• event driven
• example of usage with ZeroMQ to talk with other software (i.e. Max/MSP, Python script)
