You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: main.go
    path of file: ./repos/watcher/example/basics
    
    the code of the file until where you have to start completion: package main

import (
	"fmt"
	"log"
	"time"

	"github.com/radovskyb/watcher"
)

func main() {
	w := watcher.New()

	// Uncomment to use SetMaxEvents set to 1 to allow at most 1 event to be received
	// on the Event channel per watching cycle.
	//
	// If SetMaxEvents is not set, the default is to send all events.
	// w.SetMaxEvents(1)

	// Uncomment to only notify rename and move events.
	// w.FilterOps(watcher.Rename, watcher.Move)

	// Uncomment to filter files based on a regular expression.
	//
	// Only files that match the regular expression during file listing
	// will be watched.
	// r := regexp.MustCompile("^abc$")
	// w.AddFilterHook(watcher.RegexFilterHook(r, false))

	go func() {
		for {
			select {
			case event := <-w.Event:
				fmt.Println(event) // Print the event's info.
			case err := <-w.Error:
				log.Fatalln(err)
			case <-w.Closed:
				return
			}
		}
	}()

	// Watch
    
func main() {
	w := watcher.New()

	// being watched and their paths.
	for path, f := range w.WatchedFiles() {
		fmt.Printf("%s: %s\n", path, f.Name())
	}

	fmt.Println()

	// Trigger 2 events after watcher started.
	go func() {
		w.Wait()
		w.TriggerEvent(watcher.Create, nil)
		w.TriggerEvent(watcher.Remove, nil)
	}()

	// Start the watching process - it'll check for changes every 100ms.
	if err := w.Start(time.Millisecond * 100); err != nil {
