SKQueue
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.
Requirements
- Swift tools version 4
To build in older environments just replace Package.swift with this file.
Installation
Swift Package Manager
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"),Usage
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.
Example
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 |
