Re: [Haskell-cafe] inotify-alike for mac os x?

Oh -- also libevent, described at http://www.monkey.org/~provos/libevent/ : Currently, *libevent* supports */dev/pollhttp://access1.sun.com/techarticles/devpoll.html

*, *kqueue(2)http://www.freebsd.org/cgi/man.cgi?query=kqueue&apropos=0&sektion=0&format=html *, *event portshttp://developers.sun.com/solaris/articles/event_completion.html *, *select(2)*, *poll(2)* and *epoll(4)http://www.xmailserver.org/linux-patches/epoll.txt *. The internal event mechanism is completely independent of the exposed event API, and a simple update of libevent can provide new functionality without having to redesign the applications. As a result, *Libevent*allows for portable application development and provides the most scalable event notification mechanism available on an operating system. Libevent can also be used for multi-threaded applications; see Steven Grimm's explanationhttp://monkeymail.org/archives/libevent-users/2007-January/000450.html. *Libevent* should compile on Linux, *BSD, Mac OS X, Solaris and Windows.

Thanks, Matt. I see libev is available via macports. - Conal

Conal,

If I were looking to do this, I'd read the relevant parts of the libev code.

I'd like to make some FRPish toys that keep files updated to have functional relationships with other files. hinotify looks like just the sort of underlying magic I could use for efficient implementation on linux. Is there any support for mac os x? Could support be either added to hinotify or maybe inotify and a mac-friendly library be abstracted into a common Haskell interface? I'm fine with an imperative interface, since I can abstract into a functional library, which I guess would be a sort of persistent simplified FRP.
