## Gonotify
|
|
|
|
Simple Golang inotify wrapper.
|
|
|
|
[](https://godoc.org/github.com/illarion/gonotify/v2)
|
|
|
|
### Provides following primitives:
|
|
|
|
* Low level
|
|
* `Inotify` - wrapper around [inotify(7)](http://man7.org/linux/man-pages/man7/inotify.7.html)
|
|
* `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
|
|
|
|
```go
|
|
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
|
|
}
|
|
}
|
|
}
