Introduction

A cross-platform C++ library to publish and subscribe for events. Applications communicate using ZeroMQ, discover each other automatically through the integrated ZeroConf protocol or through explicit addressing using hostname and port. A defined vocabulary defines semantics for the published events, provided by ZeroBuf or using a simple Serializable interface. An optional http::Server provides a web service API in C++ applications.

Features

ZeroEQ provides the following major features:

Publish events using zeroeq::Publisher
Subscribe to events using zeroeq::Subscriber
Web service GET and PUT events using zeroeq::http::Server using REST and JSON
Asynchronous, reliable transport using ZMQ
Automatic publisher discovery using Zeroconf
Serialization of events using ZeroBuf

Building

ZeroEQ is a cross-platform toolkit, designed to run on any modern operating system, including all Unix variants. ZeroEQ uses CMake to create a platform-specific build environment. The following platforms and build environments are tested:

Linux: Ubuntu 14.04, RHEL 6 using gcc 4.8
Windows: 8 using Visual Studio 12
Mac OS X: 10.9 and 10.10 using clang 6

ZeroEQ requires the following external, pre-installed dependencies:

ZeroMQ 4.0 or later
Boost (tested with 1.54) for unit tests

Building from source is as simple as:

git clone https://github.com/HBPVIS/ZeroEQ.git
mkdir ZeroEQ/build
cd ZeroEQ/build
cmake ..
make
