Examples

Import Github repository

arena https://github.com/finestructure/Gala
➡️ Package: https://github.com/finestructure/Gala @ from(0.2.1)
🔧 Resolving package dependencies… 
📔 Libraries found: Gala
✅ Created project in folder 'Arena-Playground'

Using Github shorthand syntax

You can skip the protocol and domain when referring to Github projects:

arena finestructure/Gala
➡️ Package: https://github.com/finestructure/Gala @ from(0.2.1)
🔧 Resolving package dependencies…
📔 Libraries found: Gala
✅ Created project in folder 'Arena-Playground'

Import local repository

arena ~/Projects/Parser
➡️ Package: file:///Users/sas/Projects/Parser @ path
🔧 Resolving package dependencies…
📔 Libraries found: Parser
✅ Created project in folder 'Arena-Playground'

Import both

arena ~/Projects/Parser finestructure/Gala
➡️ Package: file:///Users/sas/Projects/Parser @ path
➡️ Package: https://github.com/finestructure/Gala @ from(0.2.1)
🔧 Resolving package dependencies…
📔 Libraries found: Parser, Gala
✅ Created project in folder 'Arena-Playground'

Specifying versions

In case you want to fetch a particular revision, range of revisions, or branch, you can use a syntax similar to the one used in a Package.swift file. Here's what's supported and the corresponding package dependecy that it will create in the generated project:

• https://github.com/finestructure/Gala@0.1.0

→ .package(url: "https://github.com/finestructure/Gala", exact: "0.1.0")

• https://github.com/finestructure/Gala@from:0.1.0

→ .package(url: "https://github.com/finestructure/Gala", from: "0.1.0")

• "https://github.com/finestructure/Gala@0.1.0..<4.0.0"

→ .package(url: "https://github.com/finestructure/Gala", "0.1.0"..<"4.0.0")

• https://github.com/finestructure/Gala@0.1.0...4.0.0

→ .package(url: "https://github.com/finestructure/Gala", "0.1.0"..<"4.0.1")

• https://github.com/finestructure/Gala@branch:master

→ .package(url: "https://github.com/finestructure/Gala", branch: "master")

• https://github.com/finestructure/Gala@revision:7235531e92e71176dc31e77d6ff2b128a2602110

→ .package(url: "https://github.com/finestructure/Gala", revision: "7235531e92e71176dc31e77d6ff2b128a2602110")

Make sure to properly quote the URL if you are using the ..< range operator. Otherwise your shell will interpret the < character as input redirection.

Adding another dependency

Arena does not currently support adding further dependencies to an existing playground. However, since its dependencies are managed via the PlaygroundDependencies package, you can simply add further entries to its Package.swift file - just like you would when extending any other package manifest.

Here's what this looks like:

[Adding a dependency]

How to install Arena

Homebrew

You can install Arena with Homebrew:

brew install finestructure/tap/arena

Mint

You can install Arena with Mint:

mint install finestructure/arena

Make

Last not least, you can build and install arena via the included Makefile by running:

make install

This will copy the binary arena to /usr/local/bin.

Overriding the default playground code

Be default, Arena adds import statements for the library targets it finds in a package.

As a package author, you can override this behaviour by adding a file .arena-sample.swift to the top level of your repository. The contents of this file will be used as the playground source code.

Parser is a Swift package that comes with a .arena-sample.swift file.

Why Arena?

Arena – Spanish for "sand" – is abundant in playgrounds. And also, sometimes you've got to take your source code to the arena for a fight 😅

Compatibility

Starting with version 1.0, arena requires Xcode 12. Xcode 12 brings a number of improvements that make playgrounds work much better than previous versions of Xcode. Also, arena now creates a simpler project structer that can be manually edited to add more dependencies.

If you want to use arena with Xcode 11, please use the latest 0.x release.

Playground books created by arena should run on macOS as well as iOS. Please bear in mind that the Swift packages you import when creating playground books will need to be iOS compatible.

Note that while creating playgrounds requires macOS 10.15+ and Swift 5.3, the resulting playgrounds should be supported on a wider range of operating system and compiler versions. This will mainly depend on the packages you are importing.
