package inotify

import "golang.org/x/exp/inotify"

Package inotify implements a wrapper for the Linux inotify system.

Example:

watcher, err := inotify.NewWatcher()
if err != nil {
    log.Fatal(err)
}
err = watcher.Watch("/tmp")
if err != nil {
    log.Fatal(err)
}
for {
    select {
    case ev := <-watcher.Event:
        log.Println("event:", ev)
    case err := <-watcher.Error:
        log.Println("error:", err)
    }
}

type Event

type Event struct {
    Mask   uint32 // Mask of events
    Cookie uint32 // Unique cookie associating related events (for rename(2))
    Name   string // File name (optional)
}

func (*Event) String

func (e *Event) String() string

String formats the event e in the form "filename: 0xEventMask = IN_ACCESS|IN_ATTRIB_|..."

type Watcher

type Watcher struct {
    Error chan error  // Errors are sent on this channel
    Event chan *Event // Events are returned on this channel
    // contains filtered or unexported fields
}

func NewWatcher

func NewWatcher() (*Watcher, error)

NewWatcher creates and returns a new inotify instance using inotify_init(2)

func (*Watcher) AddWatch

func (w *Watcher) AddWatch(path string, flags uint32) error

AddWatch adds path to the watched file set. The flags are interpreted as described in inotify_add_watch(2).

func (*Watcher) Close

func (w *Watcher) Close() error

Close closes an inotify watcher instance It sends a message to the reader goroutine to quit and removes all watches associated with the inotify instance

func (*Watcher) RemoveWatch

func (w *Watcher) RemoveWatch(path string) error

RemoveWatch removes path from the watched file set.

func (*Watcher) Watch

func (w *Watcher) Watch(path string) error

Watch adds path to the watched file set, watching all events.
