Force watcher type

[tucari]

Hi all,

Is there a simple way to force which filesystem watcher is used for events? I.e can I force kqueue to be used instead of FSEvents on MacOS?

Thanks

It looks like you should be able to build with go run build.go -tags kqueue, but it doesn’t work out of the box, the following patch makes it build:

diff --git a/lib/fs/basicfs_watch_eventtypes_kqueue.go b/lib/fs/basicfs_watch_eventtypes_kqueue.go

Obviously, this has never been tested by anyone, but it might work.
