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.
Features
$ marathon create helloWorld "import Foundation; print(\"Hello world\")"
$ marathon run helloWorld
> Hello world
$ marathon add https://github.com/JohnSundell/Files.git
...and use it without any additional work
import Files
for file in try Folder(path: "MyFolder").files {
print(file.name)
}
$ marathon update
$ marathon edit helloWorld
...or in your favorite text editor
$ marathon edit helloWorld --no-xcode
$ marathon run https://github.com/johnsundell/testdrive.git
...using only a GitHub username & repository name:
$ marathon run johnsundell/testdrive
$ marathon install helloWorld
$ helloWorld
> Hello world
...you can even install remote scripts (+ their dependencies) from a URL:
$ marathon install https://raw.githubusercontent.com/JohnSundell/Marathon-Examples/master/AddSuffix/addSuffix.swift
$ cd myImages
$ addSuffix "@2x"
> Added suffix "@2x" to 15 files
...or from a GitHub repository:
$ marathon install johnsundell/testdrive
$ testdrive
import Files // marathon:https://github.com/JohnSundell/Files.git
print(Folder.current.path)
...or specify your dependencies using a Marathonfile
:
$ echo "https://github.com/JohnSundell/Files.git" > Marathonfile
Installing
On macOS
Using Make (recommended):
$ git clone https://github.com/JohnSundell/Marathon.git
$ cd Marathon
$ make
Using the Swift Package Manager:
$ git clone https://github.com/JohnSundell/Marathon.git
$ cd Marathon
$ swift build -c release -Xswiftc -static-stdlib
$ cp -f .build/release/Marathon /usr/local/bin/marathon
Using Mint:
$ mint install JohnSundell/Marathon
Using Homebrew (not recommended, due to slow update cycle):
brew install marathon-swift
On Linux
$ git clone https://github.com/JohnSundell/Marathon.git
$ cd Marathon
$ swift build -c release
$ cp -f .build/release/Marathon /usr/local/bin/marathon
If you encounter a permissions failure while installing, you may need to prepend sudo
to the commands.
To update Marathon, simply repeat any of the above two series of commands, except cloning the repo.
Requirements
Marathon requires the following to be installed on your system:
- Swift 4.1 or later (bundled with Xcode 9.3 or later)
- Git
- Xcode (if you want to edit scripts using it)
Examples
Check out this repository for a few example Swift scripts that you can run using Marathon.
Specifying dependencies inline
Scripting usually involves using 3rd party frameworks to get your job done, and Marathon provides an easy way to define such dependencies right when you are importing them in your script, using a simple comment syntax:
import Files // marathon:https://github.com/JohnSundell/Files.git
import Unbox // marathon:https://github.com/JohnSundell/Unbox.git
Specifying your dependencies ensures that they will always be installed by Marathon before your script is run, edited or installed - making it super easy to share scripts with your friends, team or the wider community. All you have to do is share the script file, and Marathon takes care of the rest!
Using a Marathonfile
If you prefer to keep your dependency declarations separate, 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 either:
- The URL to a git repository of a local or remote package to install before running your script.
- The path to another script that should be linked to your script before running it.
Here is an example of a Marathonfile
:
https://github.com/JohnSundell/Files.git
https://github.com/JohnSundell/Unbox.git
https://github.com/JohnSundell/Wrap.git
~/packages/MyPackage
otherScript.swift
Shell autocomplete
Marathon includes autocomplete for the zsh
and fish
shells (PRs adding support for other shells is more than welcome!). To enable it, do the following:
-
zsh
:- Add the line
fpath=(~/.marathon/ShellAutocomplete/zsh $fpath)
to your~/.zshrc
file. - Add the line
autoload -Uz compinit && compinit -i
to your~/.zshrc
file if it doesn't already contain it. - Restart your terminal.
- Add the line
-
fish
:cp -f ~/.marathon/ShellAutocomplete/fish/marathon.fish ~/.config/fish/completions
You can now type marathon r
and have it be autocompleted to marathon run
