path-unwatchclj/s
(path-unwatch pw k)Remove a watch on the PathWatchable. k is the key given to
path-watch when adding the watch.
Remove a watch on the PathWatchable. `k` is the key given to `path-watch` when adding the watch.
path-watchclj/s
(path-watch pw k path f)Watch for changes under path on the PathWatchable. The
k is a key that can be used to remove the watch with
path-unwatch. The path should be a vector.
The f will be called each time the value at path could
have changed. It'll be called as (f old-val new-val changed-paths),
where old-val is the previous value at path, new-val is the new
value, and changed-paths is a set of more specific subpaths that
have changed (or #{[]}) if the specifics aren't available.
