To use the SwiftShell library in a SwiftPM project, add the following line to the dependencies in your Package.swift file:

.package(url: "https://github.com/taji-taji/swift-shell.git", from: "1.0.0")

Include "SwiftShell" as a dependency for your executable target:

Finally, add import SwiftShell to your source code.

Example

Basic Usage

import SwiftShell

let shell = Shell()

do {
    // Shell is implemented with `callAsFunction`.
    let output = try shell("ls", arguments: ["-l", "-a"])
    print(output)
} catch {
    print(error)
}

Async / Await

import SwiftShell

let shell = Shell()

Task {
    async let output1 = shell("brew install awesome-tool")
    async let output2 = shell("bundle install")

    let result = try await (output1, output2)
    print(result.0)
    print(result.1)
}
