Swift Commands

SPM CocoaPods CI Status License Platform

Swift utilities for running commands.

The Commands module allows you to take a system command as a string and return the standard output.

API documentation can be found here.

Usage

import Commands

Bash

Execute shell commands.

let result = Commands.Task.run("bash -c ls")

Or

let result = Commands.Task.run(["bash", "-c", "ls"])

Or

let result = Commands.Bash.run("ls")

Python

Execute python scripts.

let result = Commands.Task.run("python main.py")

Execute python commands.

let result = Commands.Task.run("python -c import base64; print(base64.b64encode('qiuzhifei').decode('ascii'))")

Or

let result = Commands.Python.run("import base64; print(base64.b64encode('qiuzhifei').decode('ascii'))")

Ruby

Execute ruby scripts.

let result = Commands.Task.run("ruby main.rb")

Execute ruby commands.

let result = Commands.Task.run("ruby -e require 'base64'; puts Base64.encode64('qiuzhifei')")

Or

let result = Commands.Ruby.run("require 'base64'; puts Base64.encode64('qiuzhifei')")

Alias

Create a shortcut name for a command.

let node = Commands.Alias("/usr/local/bin/node", dashc: "-e")
let result = node.run("console.log('qiuzhifei')")

Setting global environment variables

Commands.ENV.global["http_proxy"] = "http://127.0.0.1:7890"
Commands.ENV.global.add(PATH: "/Users/zhifeiqiu/.rvm/bin")

Making Commands

let request: Commands.Request = "ruby -v"

Or

let request: Commands.Request = ["ruby", "-v"]

Or

let request = Commands.Request(executableURL: "ruby", arguments: "-v")

Change environment variables

var request: Commands.Request = "ruby -v"
request.environment?.add(PATH: "/usr/local/bin")
request.environment?["http_proxy"] = "http://127.0.0.1:7890"
request.environment?["https_proxy"] = "http://127.0.0.1:7890"
request.environment?["all_proxy"] = "socks5://127.0.0.1:7890"

let result = Commands.Task.run(request)

Result Handler

Returns the Commands.Result of running cmd in a subprocess.

let result = Commands.Task.run("ruby -v")
switch result {
case .Success(let request, let response):
  debugPrint("command: \(request.absoluteCommand), success output: \(response.output)")
case .Failure(let request, let response):
  debugPrint("command: \(request.absoluteCommand), failure output: \(response.errorOutput)")
}

Adding Commands as a Dependency

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

let package = Package(
    // name, platforms, products, etc.
    dependencies: [
        .package(url: "https://github.com/qiuzhifei/swift-commands", from: "0.6.0"),
        // other dependencies
    ],
    targets: [
        .target(name: "<command-line-tool>", dependencies: [
            .product(name: "Commands", package: "swift-commands"),
        ]),
        // other targets
    ]
)

CocoaPods (OS X 10.9+)

You can use CocoaPods to install Commands by adding it to your Podfile:

pod 'Commands',        '~> 0.6.0'

QuickStart

git clone https://github.com/QiuZhiFei/swift-commands
