Welcome to [ShellOut](https://github.com/JohnSundell/ShellOut), a simple package that enables you to easily “shell out” from a Swift script or command line tool.

Usage

Just call shellOut(), and specify what command you want to run, along with any arguments you want to pass:

let output = try shellOut(to: "echo", arguments: ["Hello world"])
print(output) // Hello world

You can also easily run a series of commands at once, optionally at a given path:

try shellOut(to: ["mkdir NewFolder", "echo \"Hello again\" > NewFolder/File"], at: "~/CurrentFolder")
let output = try shellOut(to: "cat File", at: "~/CurrentFolder/NewFolder")
print(output) // Hello again

In case of an error, ShellOut will automatically read STDERR and format it nicely into a typed Swift error:

do {
    try shellOut(to: "totally-invalid")
} catch {
    let error = error as! ShellOutError
    print(error.message) // Prints STDERR
    print(error.output) // Prints STDOUT
}

Pre-defined commands

Another way to use ShellOut is by executing pre-defined commands, that enable you to easily perform common tasks without having to construct commands using strings. It also ships with a set of such pre-defined commands for common tasks, such as using Git, SPM and manipulating the file system.

Use Git

try shellOut(to: .gitInit())
try shellOut(to: .gitClone(url: repositoryURL))
try shellOut(to: .gitCommit(message: "A scripted commit!"))
try shellOut(to: .gitPush())
try shellOut(to: .gitPull(remote: "origin", branch: "release"))
try shellOut(to: .gitSubmoduleUpdate())
try shellOut(to: .gitCheckout(branch: "my-feature"))

Handle files, folders and symlinks

try shellOut(to: .createFolder(named: "folder"))
try shellOut(to: .createFile(named: "file", contents: "Hello world"))
try shellOut(to: .moveFile(from: "path/a", to: "path/b"))
try shellOut(to: .copyFile(from: "path/a", to: "path/b"))
try shellOut(to: .openFile(at: "Project.xcodeproj"))
try shellOut(to: .readFile(at: "Podfile"))
try shellOut(to: .removeFile(from: "path/a"))
try shellOut(to: .createSymlink(to: "target", at: "link"))
try shellOut(to: .expandSymlink(at: "link"))

Use The Swift Package Manager

try shellOut(to: .createSwiftPackage(withType: .executable))
try shellOut(to: .updateSwiftPackages())
try shellOut(to: .generateSwiftPackageXcodeProject())
try shellOut(to: .buildSwiftPackage())
try shellOut(to: .testSwiftPackage())

Don't see what you're looking for in the list above? You can easily define your own commands using ShellOutCommand. If you've made a command you think should be included among the built-in ones, feel free to open a PR in original author repository.
