v0.9.2 backport fix #14 #33
Cross platform: Windows, Linux, BSD and OS X.
There is a fork being actively developed with a new API in preparation for the Go Standard Library: github.com/go-fsnotify/fsnotify
package main import ( "log" "github.com/howeyc/fsnotify" ) func main() { watcher, err := fsnotify.NewWatcher() if err != nil { log.Fatal(err) } done := make(chan bool) // Process events go func() { for { select { case ev := <-watcher.Event: log.Println("event:", ev) case err := <-watcher.Error: log.Println("error:", err) } } }() err = watcher.Watch("testDir") if err != nil { log.Fatal(err) } <-done /* ... do stuff ... */ watcher.Close() }
For each event:
When a file is moved to another directory is it still being watched?
No (it shouldn't be, unless you are watching where it was moved to).
When I watch a directory, are all subdirectories watched as well?
No, you must add watches for any directory you want to watch (a recursive watcher is in the works #56).
Do I have to watch the Error and Event channels in a separate goroutine?
As of now, yes. Looking into making this single-thread friendly (see #7)
Why am I receiving multiple events for the same file on OS X?
Spotlight indexing on OS X can result in multiple events (see #62). A temporary workaround is to add your folder(s) to the Spotlight Privacy settings until we have a native FSEvents implementation (see #54).
How many files can be watched at once?
There are OS-specific limits as to how many watches can be created:
