Is there anything in the standard library to help writing a file watcher? I want to monitor a single file for changes and if a change is detected call a function. Is there any existing libraries to do this in D as it must be cross-platform as much as possible?

I have something like this implemented for windows. It watches a entire directory including subdirectories (optional) and tells you which files changed upon request:

I don't think its possible to imiplement this cross-plattform. You will have to reimplement for every plattform you need it on.

For Linux you can use inotify

I think the corresponding for Mac OS X is fsevents:

Hmmm.. this is what i first thought. I think i'll implement a simple watcher based on modification times as a first iteration. Then if time allows add platform specific solutions based on the above. Thanks.

may help with platform specific solutions.
