Simple Golang inotify wrapper.
-
Low level
Inotify- wrapper around inotify(7)InotifyEvent- generated file/folder event. ContainsName(full path),Wd- watch descriptor andMaskthat describes the event.
-
Higher level
FileWatcher- higher level utility, helps to watch the list of files for changes, creation or removalDirWatcher- higher level utility, recursively watches given root folder for added, removed or changed files.FileEvent- embedsInotifyEventand keeps additional fieldEofto notify user that there will be no more events.
Use FileWatcher and DirWatcher as an example and build your own utility classes.
package main import ( "fmt" "github.com/illarion/gonotify/v3" "time" "context" ) func main() { ctx, cancel := context.WithCancel(context.Background()) watcher, err := gonotify.NewDirWatcher(ctx, gonotify.IN_CREATE|gonotify.IN_CLOSE, "/tmp") if err != nil { panic(err) } main: for { select { case event := <-watcher.C: fmt.Printf("Event: %s\n", event) if event.Is(gonotify.IN_CREATE) { fmt.Printf("File created: %s\n", event.Name) } if event.IsAny(gonotify.IN_CLOSE, gonotify.IN_CLOSE_WRITE) { fmt.Printf("File closed: %s\n", event.Name) } case <-time.After(5 * time.Second): fmt.Println("Good bye!") cancel() break main } } // Wait for watcher to finish all internal goroutines <-watcher.Done() fmt.Println("Watcher is done") }MIT.
