SKQueue is a Swift libary used to monitor changes to the filesystem. It wraps the part of the kernel event notification interface of libc, kqueue. This means SKQueue has a very small footprint and is highly scalable, just like kqueue.
To build in older environments just replace Package.swift
with this file.
To use SKQueue, add the code below to your dependencies
in Package.swift
.
Then run swift package fetch
to fetch SKQueue.
.package(url: "https://github.com/daniel-pedersen/SKQueue.git", from: "1.2.0"),
To monitor the filesystem with SKQueue
, you first need a SKQueueDelegate
instance that can accept notifications.
Paths to watch can then be added with addPath
, as per the example below.
import SKQueue
class SomeClass: SKQueueDelegate {
func receivedNotification(_ notification: SKQueueNotification, path: String, queue: SKQueue) {
print("\(notification.toStrings().map { $0.rawValue }) @ \(path)")
}
}
let delegate = SomeClass()
let queue = SKQueue(delegate: delegate)!
queue.addPath("/Users/steve/Documents")
queue.addPath("/Users/steve/Documents/dog.jpg")
Action | Sample output |
---|---|
Add or remove file in /Users/steve/Documents |
["Write"] @ /Users/steve/Documents |
Add or remove directory in /Users/steve/Documents |
["Write", "SizeIncrease"] @ /Users/steve/Documents |
Write to file /Users/steve/Documents/dog.jpg |
["Rename", "SizeIncrease"] @ /Users/steve/Documents/dog.jpg |
