Marathon makes it easy to write, run and manage your Swift scripts
Swift Makefile
Latest commit 3784492 Mar 26, 2017 @JohnSundell Don’t evaluate already added packages from Marathonfile
This patch makes using a Marathonfile a lot faster, since now URLs of already
added packages are not evaluated, their names are not resolved, etc.


Welcome to Marathon, a command line tool that makes it easy to write, run and manage your Swift scripts. It's powered by the Swift Package Manager and requires no modification to your existing scripts or dependency packages.


🐣 Create scripts

$ marathon create helloWorld "import Foundation; print(\"Hello world\")"

🏃‍♀️ Run scripts

$ marathon run helloWorld
> Hello world

📦 Hassle free dependency management. Simply add a package...

$ marathon add

...and use it without any additional work

import Files

for file in try Folder(path: "MyFolder").files {

🚀 Update all of your scripting dependencies with a single call

$ marathon update

Edit, run & debug your scripts using Xcode...

$ marathon edit helloWorld

...or in your favorite text editor

$ marathon edit helloWorld --no-xcode

👪 Share your scripts with your team and automatically install their dependencies:

$ echo "" > Marathonfile
$ marathon run mySharedScript


Using Make:

$ git clone
$ cd Marathon
$ make

Using the Swift Package Manager:

$ git clone
$ cd Marathon
$ swift build -c release -Xswiftc -static-stdlib
$ cp -f .build/release/Marathon /usr/local/bin/marathon


Check out this repository for a few example Swift scripts that you can run using Marathon.

Using a Marathonfile

To easily be able to define depenencies for a script in a declarative way, you can create a Marathonfile in the same folder as your script. This file is simply a new line separated list of URLs pointing to packages that should be installed before running the script. By doing this you can ensure that the required dependencies will be installed when sharing your script with team members, friends or the wider community.

Here is an example of a Marathonfile:
