Recursively watch a directory for modifications and publish file content to an MQTT broker
Project description
This simple Python program portably watches a directory recursively and publishes the content of newly created and modified files as payload to an MQTT broker. Files which are deleted are published with a NULL payload.
The path to the directory to watch recursively (default .), as well as a list of files to ignore (*.swp, *.o, *.pyc), the broker host (localhost) and port number (1883) must be specified in the program, together with the topic prefix to which to publish to (watch/).
Installation
git clone https://github.com/jpmens/mqtt-watchdir.git cd mqtt-watchdir virtualenv watchdir source watchdir/bin/activate pip install -e .
Configuration
TOPIC_PREFIX is prepended onto the relative path of the file being accessed, and may be None.
Testing
Launch mosquitto_sub:
mosquitto_sub -v -t 'watch/#'
Launch this program and, in another terminal, try something like this:
echo Hello World > message echo JP > myname rm myname
whereupon, on the first window, you should see:
watch/message Hello World watch/myname JP watch/myname (null)
