There *should* be a way to know what changed, at least in Linux as inotify allows this IIRC. Someone already wrote an FFI wrapper for inotify, hopefully it suits your needs (if it does, it would be cool to send a Pull Request to turn the repo in a Racket package, so that it can be put on pkgn.racket-lang.org): https://github.com/samdphillips/racket-inotify As for monitoring subdirectories, unfortunately (and surprisingly) this is not possible with inotify on Linux. From the man page: Inotify monitoring of directories is not recursive: to monitor subdirectories under a directory, additional watches must be created. Fortunately, this should be easy enough to do in Racket, thanks to the wonderful in-directory: (define (watch-recursively d) (for ([subnode (in-sequences (in-value d) (in-directory d))]) (when (directory-exists? subnode) ;; filter out files (watch-the-directory subnode))) This might take a while (and use up some resources) when watching a large directory :-( . -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
