digitalmars.D.announce - Eclipse Paho D Library (finally) started

Hey All,

First, my apologies. Over a year ago I had promised to put up a D 
library for MQTT, but a number of factors conspired against me in 
the intervening time.

But this week, I finally got an initial version loaded. It will 
be a part of the Eclipse Paho libraries for MQTT, and an official 
1.0 release should come about this fall.

The first release will be a wrapper around the Paho C library, 
and thus should be protocol compliant and fairly feature-complete 
at the offset. It also follows the Java and C++ API's pretty 
closely, so should make it easy for people to jump around between 
languages.

The repository is here:

https://github.com/eclipse/paho.mqtt.d

I'm still quite a D novice, so any help, hints, tips, or bug 
reports would be appreciated.

Thanks,
Frank Pagliughi

This would be a perfect time to mention what MQTT is.

Ha. Yes.

MQTT (Message Queue Telemetry Transport) is a broker-based 
publish/subscribe messaging system for IoT devices. It's a fairly 
light weight protocol that sits on top of TCP and makes 
provisions for systems that have unreliable connections.

So, basically, it's for small devices out in the real world that 
collect data and want to send that data back home to a cloud 
server.

It originated out of IBM more than a decade ago, and some of 
their code was donated to Eclipse and found a home under the 
"Paho" project. Since then Eclipse has started to gather a large 
number of IoT projects for both device-side data collection and 
for server-side analytics.
http://iot.eclipse.org/projects

An MQTT client could be a device that is gathering and publishing 
data, or it could be a server application that is subscribing to 
that data, aggregating, analyzing, or storing it. I figured that 
D would work pretty well on either side of that.

I would be nice to have something that is vibe.d compatible.

I had a vague idea of one or two similar projects underway. But 
90% of the code I just posted was written in early 2015. The 
initial delay getting it published was with the Eclipse legal 
process which dragged on for a few months, and just as it was 
done, they decided to move their development to GitHub. By that 
time I wasn't doing anything with D or MQTT, and the inertia died.

The idea from the beginning was do a fairly quick/simple wrapper 
library around the Paho C library, which would get the D version 
feature-complete and fully compliant in short time. Then the idea 
was to move on to a full D implementation for version 2.0. If 
there were any interest.

So this version doesn't do any of its own I/O; that's left to the 
C layer. Thus it doesn't require - and I'm not sure how it could 
be made compatible with - vibe.d

And originally I believe the Eclipse folks had wanted to keep 
external libraries to a minimum, but now exceptions to the rule 
seem to be the norm. So using vibe.d would probably be fine, 
assuming no license issues.
