Gonotify

Simple Golang inotify wrapper.

Provides following primitives:

• Low level

  • Inotify - wrapper around inotify(7)
  • InotifyEvent - generated file/folder event. Contains Name (full path), watch descriptior and Mask that describes the event.

• Higher level

  • FileWatcher - higher level utility, helps to watch the list of files for changes, creation or removal
  • DirWatcher - higher level utility, recursively watches given root folder for added, removed or changed files.
  • FileEvent - embeds InotifyEvent and keeps additional field Eof to notify user that there will be no more events.

Use FileWatcher and DirWatcher as an example and build your own utility classes.

Usage

package main

import (
	"fmt"
	"github.com/illarion/gonotify/v2"
	"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)
	}

	for {
		select {
		case event := <-watcher.C:
			fmt.Printf("Event: %s\n", event)

			if event.Mask&gonotify.IN_CREATE != 0 {
				fmt.Printf("File created: %s\n", event.Name)
			}

			if event.Mask&gonotify.IN_CLOSE != 0 {
				fmt.Printf("File closed: %s\n", event.Name)
			}

		case <-time.After(5 * time.Second):
			fmt.Println("Timeout")
			cancel()
			return
		}
	}
}
