RawTerm

它的功能非常简单：从终端读取输入，一次读取一个字符，无需用户按下回车键，也不会回显字符。

使用方法很简单：首先调用 enableRawMode() 启用原始模式，然后重复调用 readChar() 逐个读取字符。最后，在完成时调用 disableRawMode() 禁用原始模式。

它支持 Unicode，包括表情符号。 如果您收到无效字符，请确保您的终端配置为使用 UTF8 编码。

不要在 Xcode 或 Swift Playgrounds 中使用终端进行测试，请使用功能齐全的独立终端。

使用 Package.swift

// Add to your package dependencies
.package(url: "https://github.com/Swonkie/RawTerm.git", from: "0.1.0")

// Add to your target dependencies
.product(name: "RawTerm", package: "RawTerm")

// Import the module in your code
import RawTerm

示例

一个简单的拼写辅助工具

import RawTerm

@main
struct Spell {

	static func main() throws {
		print("Type or paste some text\nPress Esc to quit\n")

		try enableRawMode()
		defer {
			try! disableRawMode()
		}

		while true {
			// print requires an extra \r at the end when in raw mode

			guard let input = try? readChar() else {
				print("Invalid input - make sure the terminal uses UTF8.\r")
				continue
			}
			if input == CharCode.ESC {
				break
			}

			if let spelling = dict[input.lowercased()] {
				print("\(input)  \(spelling)\r")
			} else {
				print("\(input)  \(input)\r")
			}
		}
	}
	
	static let dict = [
		"a": "Alpha",
		"b": "Bravo",
		"c": "Charlie",
		"d": "Delta",
		"e": "Echo",
		"f": "Foxtrott",
