Sake - Swift Make

Sake is a Swift command line tool that helps you automate tasks in your projects. It's heavily inspired by Makefile and Rake.

Path to 1.0.0 🚴

Sake hasn't reached the first major version yet. We are still defining many things around how Sake works and how the API works. These decissions might result into breaking changes in the Sake APIs. Once we reach the version 1.0.0 we'll use semantic versioning ensuring that only major versions include breaking changes.

We kindly ask you to use Sake on your own responsibility during this early stage and encourage you to participate in discussions that might determine what Sake final version looks like.

Motivation 💅

Why automating tasks using shell scripting or Ruby when you can do it in Swift, a language you are already familiar with? Sake aims to provide a command line tool and the foundation to automate your tasks in Swift.

Installation 🥑

You can easily install sake using Homebrew:

brew tap xcodeswift/sake git@github.com:xcodeswift/sake.git
brew install sake

Setup ⚒

1. Git clone the project git clone https://github.com/xcodeswift/sake.git.
2. Build swift build.

Sakefile

Sakefile is the file that defines your project tasks:

// #!/usr/bin/env sake --path
import SakefileDescription

Sake(tasks: [
  Task("build", description: "Builds the project") {
    // Here is where you define your build task
  }],
  hooks: [
    .beforeAll({ print("Before all the tasks" )})
  ]
)

Usage 👩🏻‍💻

Creating a Sakefile.swift 📝

You can create an empty Sakefile.swift running the following command:

sake init

Working on the Sakefile.swift 💼

You can edit the Sakefile.swift using any text editor. Nonetheless, we recommend you to use Xcode since you'll get syntax highlighting and code autocompletion for free. Sake provides a command to generate the Xcode project where you can edit the Sakefile.swift. You can generate the command by running:

sake generate-xcodeproj

⚠️ Note: You shouldn't modify the content in the main.swift file. Your Sakefile.swift should contain a top level variable named sake in order for Xcode to be able to run Sake.

To define the arguments to be passed to Sake you can edit the Scheme as shown in the screenshot below and add your arguments there:

Tasks ✅

Run a task

sake task name_of_the_task

List all the tasks

sake tasks

Shebang: You can run your Sakefile.swift directly calling ./Sakefile.swift

Utils ☕️

Sake includes some utils in SakefileDescription that might be useful for your tasks:

// Shell (examples)
try Utils.shell.runAndPrint(bash: "swift build")
try Utils.shell.run(bash: "swift build")

// Git (examples)
let branch = try Utils.git.branch()
let anyChanges = try Utils.git.anyChanges()
try Utils.git.commit(message: "my commit message")
try Utils.git.tag("3.0.0)
let tagstry Utils.git.tags()

// HTTP (examples)
let response = try Utils.http.execute(request: request, parse: { try GitHubRelease.init(data: $0) })

Sakefile Guidelines 🎨

The Swift code written in the Sakefile.swift file should meet the following guidelines:

• It shouldn't fail the execution either using fatalError or force unwrapping nil values. Failing the execution causes the tool to print the stack trace in the console. Instead throw errors that are handled by Sake and nicely printed into the console.
• Code should be synchronous and tasks should be completed by the time the closure execution ends.

Alternatives 🤩

Sake is not the only tool that helps with automation. There are other tools that are also worth considering:

Tool	Link	Language
Fastlane	fastlane	Ruby
Beak	yonaskolb/beak	Swift
Rake	ruby/rake	Ruby

If you know any other tool that you think fits into this section feel free to open a PR proposing it.
