Detecting filesystem events

Warning

Needs testing/refactoring! Last time, this failed to work!

Go

package main

import (
    "fmt"

    "github.com/fsnotify/fsnotify"
)

// main
func main() {

    // creates a new file watcher
    watcher, err := fsnotify.NewWatcher()
    if err != nil {
        fmt.Println("ERROR", err)
    }
    defer watcher.Close()

    //
    done := make(chan bool)

    //
    go func() {
        for {
            select {
            // watch for events
            case event := <-watcher.Events:
                fmt.Printf("EVENT! %#v\n", event)

                // watch for errors
            case err := <-watcher.Errors:
                fmt.Println("ERROR", err)
            }
        }
    }()

    // out of the box fsnotify can watch a single file, or a single directory
    if err := watcher.Add("/Users/skdomino/Desktop/test.html"); err != nil {
        fmt.Println("ERROR", err)
    }

    <-done
}
