Drop-in replacement for ParsableCommand to use async/await in swift-argument-parser commands
.package(url: "https://github.com/christopherweems/_AsyncParsableCommand.git", from: "0.0.3")


A drop-in replacement for ParsableCommand allowing you to use async/await in ParsableCommand.run() without managing tasks.

Hopefully just here to hold you over until async/await support lands in swift-argument-parser.


import ArgumentParser
import AsyncParsableCommand

struct Countdown: _AsyncParsableCommand {
    @Argument var count: Int
    func run() async throws {
        var remaining = count
        while 0 < remaining {
            await Task.sleep(1_000_000_000)
            remaining -= 1
        print("Countdown complete!")
