docopt.swift is a Swift port of docopt, now Linux compatible.
docopt.swift helps you create most beautiful command-line interfaces easily. This project is a friendly fork of the docopt team original work, but which compiles on Linux and is also Marathon compatible.
I made little changes to the project, forked from @samdeane original PR. A minimally working example looks like:
import Foundation
import Glibc
import Docopt // marathon: /home/luis/Dropbox/Documentos/Coding/Swift/docopt.swift
let doc : String = """
Not a serious example.
Usage:
calculator_example.py <value> ( ( + | - | * | / ) <value> )...
calculator_example.py <function> <value> [( , <value> )]...
calculator_example.py (-h | --help)
Examples:
calculator_example.py 1 + 2 + 3 + 4 + 5
calculator_example.py 1 + 2 '*' 3 / 4 - 5 # note quotes around '*'
calculator_example.py sum 10 , 20 , 30 , 40
Options:
-h, --help
"""
var args = CommandLine.arguments
args.remove(at: 0)
print(args)
let result = Docopt.parse(doc, argv: args, help: true, version: "1.0")
print("Docopt result: \(result)")Swift:
