ZeroMQ

Building and Trying FileMQ

The FileMQ stack is on GitHub. It works like a classic C/C++ project:

git clone git://github.com/hintjens/filemq.git
cd filemq
./autogen.sh
./configure
make check

You want to be using the latest CZMQ master for this. Now try running the track command, which is a simple tool that uses FileMQ to track changes in one directory in another:

cd src
./track ./fmqroot/send ./fmqroot/recv

Open two file navigator windows, one into src/fmqroot/send and one into src/fmqroot/recv. Drop files into the send folder, and you’ll see them arrive in the recv folder. The server checks once per second for new files. Delete files in the send folder, and they’re deleted in the recv folder simultaneously.

I use track for things like updating my MP3 player, mounted as a USB drive. As I add or remove files in my laptop’s Music folder, the same changes happen on the MP3 player. FILEMQ isn’t a full replication protocol yet, but we’ll fix that later.
