英文:
FSNotify add watch directories while running
问题
我不太知道如何表达问题，但是这是问题的内容。
我正在使用fsnotify来监视一些目录的变化，当文件发生变化时，我会将变化同步到另一个目录。但是我想要将新创建的目录也添加到监视中，但这并没有起作用。
这是我的代码：
func Watcher() {
watcher, err := fsnotify.NewWatcher()
defer watcher.Close()
done := make(chan bool)
go func() {
for {
select {
case event := <-watcher.Events:
if file.Mode().IsDir() {
err = os.Mkdir(dest, 0755)
err = watcher.Add(dest)
}
case err := <-watcher.Errors:
log.Println("error:", err)
}
}
}()
dirs, err := readLines("dirs")
for _, el := range dirs {
err = watcher.Add(el)
}
check(err)
<-done
}
这个函数还有更长的部分，但我删除了不重要的部分。除了err = watcher.Add(dest)之外，其他都正常工作。
我该如何使其监视更多的目录？
英文:
I don't really know how to formulate the question, but here it is.
I'm using fsnotify to watch some directories for changes and when a file changes, I sync the change to another directory. But I want to add newly created directories to the watch too and it's not really working.
Here's my code:
func Watcher() {
watcher, err := fsnotify.NewWatcher()
defer watcher.Close()
done := make(chan bool)
go func() {
for {
select {
case event := <-watcher.Events:
if file.Mode().IsDir() {
err = os.Mkdir(dest, 0755)
err = watcher.Add(dest)
}
case err := <-watcher.Errors:
log.Println("error:", err)
}
}
}()
dirs, err := readLines("dirs")
for _, el := range dirs {
err = watcher.Add(el)
}
check(err)
<-done
}
The function is much longer, but I've deleted the non-important parts. Everything works, except the err = watcher.Add(dest).
How can I make it watch more directories?

这是要翻译的内容：
"它之前运行得很好，但是我弄错了一些变量。应该是watcher.Add(event.Name)而不是watcher.Add(dest)。"
英文:
It was working just fine, but I got some variables wrong. Should have been watcher.Add(event.Name) instead of watcher.Add(dest).
