polling mode doesn't work on OSX

[jaredly]

because it uses inotify, I guess? :/

That's right. It shouldn't be too hard to add another file watcher backend, it's already abstracted in lib/fs.ml. A patch would be welcome :)

See https://github.com/samoht/irmin-watcher as an example of portable filesystem watcher.

Thanks @samoht. If it's truly universal, should Jenga just adopt it?

[samoht]

it is not universal, it is targeted to fit the Irmin watcher API. Could be possible to extract something more universal from it, I know @dsheets was interested about it.

We should start a package fsnotify which only depends on inotify or fsevents depending on the platform it's on and offers a lowest common denominator interface (to start).
