digitalmars.D.learn - Can i watch folders/files for changes with D language?

Hi Everyone, i'm planning on developing a software for 
synchronizing folder contents across multiple computers. The 
software will evolve very quickly into virtual Remote Desktop 
Access system.
So i've been considering C++ for this, its the best in the market 
of all things fast at the moment (Considering the availability of 
tools and docs). But i hate just two things in the language, 
(.cpp + .h files) and no "easy" centralized package manager.
So i'm definitely considering D and Python now, but D seems to 
satisfy my needs as per this software. I've developed very good 
custom server for hardware before, and it performed very well.
So i need your help guys, can you point me to any documentation 
or libraries i can use to watch files/folders for changes 
(delete, edit, new content)?
I intend to make this a command line tool for a start, but i'll 
need a GUI sooner or later. So i also need help pointing me to 
the best available GUI library D has.

Your help will be so valuable and really appreciated sir/ma. I'll 
be waiting excitedly for your responses!

Also i'm very sorry if i didn't post this to the right 
Thread/Forum, i just found this forum and i wasn't very sure 
where i'd post this. Thanks a lot

This package seems to do what you need:
https://code.dlang.org/packages/fswatch

Thanks Everyone, you guys are simply the best! I got much more 
than i asked for, thanks a lot guys. With this awesome community 
support, i'm definitely shooting for D + python(UI)

You can use vibed:
http://vibed.org/api/vibe.core.file/DirectoryWatcher
Or just vibe-core
https://code.dlang.org/packages/vibe-core
Or
https://code.dlang.org/packages/eventcore

As a bonus you can use it for networking too.

About GUI I do not know what is the best solution. I have some experience
with GTKD, which works well for me.

Conan is the up and coming centralised package management system for
C++.

C++ may, or may not, get modules (and so remove the .cpp/.h split)
sometime before the heat death of the universe.

You should add Rust to the list of options I believe.

Not sure whether Go should be added as well, probably Yes.

Python, D, Rust, and Go, all have bindings the the various file
watching facilities in the various operating systems.

It is really a question of which GUI framework you want to use. This is
a situation where a bit of forward planning will help avoid having to
reimplement or hack in silly ways.

The two obvious candidates are Qt and GTK if you want to be cross-
platform. This then leads to the question which programming languages
have good bindings to the frameworks. I am more or less in the GTK camp
now having more or less given up on Qt, however Qt remains a very good
choice.

D, Python, and Rust have excellent bindings to GTK. Go has a good
binding. C++ binding to GTK is not bad, but I prefer the D and Rust
ones.

Python has an excellent binding to Qt (use PySide2). Obviously C++ has
an excellent binding to Qt since Qt is a C++ library. I have not
properly investigated D and Rust bindings to Qt. The Big Question=E2=84=A2 =
is
whether to use QML or not. I get the feeling the answer is yes you
probably should. The Python and Go binding for using QML are good, I
haven't tried D, Rust, or C++.

It's difficult to specifying a single best GUI library. But I'll mention 
DWT [1] [2]. It has a native look and feel and works on Windows and 
Linux (GTK).
