Announcing libasync, a cross-platform D event loop

[Etienne via Digitalmars-d]

It's finally here: https://github.com/etcimon/libasync

We all know how event loops are the foundation of more popular libraries 
Qt and Nodejs.. we now have a natively compiling async library entirely 
written in D.

This event library was tested on Win32, Linux x64, Mac OS x64, with DMD 
2.066, offers the more low-level async objects: timers, file i/o, dns 
resolver, tcp, udp, listeners, signals (cross-thread), notifications 
(same thread), and more recently (and with great efforts for 
implementing with OS X / BSD) a directory watcher.

e.g. You can run a timer with:

	import std.datetime; import std.stdio; import libasync.all;
	EventLoop evl = new EventLoop;
	auto timer = new AsyncTimer(evl);
	timer.duration(2.seconds).periodic().run({ writeln("Another 2 seconds 
have passed"); });
	while(evl.loop()) continue;

The tests may be most revealing:

A (lightly tested) vibe.d driver using all those async objects is also 
available and currently ongoing a pull request:

https://github.com/etcimon/vibe.d/tree/native-events

The incentive was to make vibe.d compile in completely native D, I'm now 
moving onto a botan C++ => D wrapper for it, I plan on moving objects to 
D over the years until the TLS library can be completely native. I thank 
Walter for the efforts on extern(C++)

Finally, I release this on the basis of an MIT license, looking forward 
to seeing our community flourishing with yet more native libraries. Code on
