This is based on webfreak's fswatch. I had problems with the API as it where because I needed to be able to watch multiple directories, filter what files are to be watched and to be robust against broken symlinks.

Lets say you want to watch a directory for changes and add all directories to be watched too.

auto fw = fileWatch();
fw.watchRecurse("my_dir");
while (true) {
    auto ev = fw.wait;
    foreach (e; ev) {
        e.match!(
        (Event.Access x) => writeln(x),
        (Event.Attribute x) => writeln(x),
        (Event.CloseWrite x) => writeln(x),
        (Event.CloseNoWrite x) => writeln(x),
        (Event.Create x) { fw.watchRecurse(x.path); },
        (Event.Delete x) => writeln(x),
        (Event.DeleteSelf x) => writeln(x),
        (Event.Modify x) => writeln(x),
        (Event.MoveSelf x) => writeln(x),
        (Event.Rename x) => writeln(x),
        (Event.Open x) => writeln(x),
        );
    }
}
