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 {
print("\(remaining)!")
await Task.sleep(1_000_000_000)
remaining -= 1
}
print("Countdown complete!")
}
}
