Commandy

Commandy is Cli framework.

Usage

Implement Command

non option

enum Stash: Command {
    static func run() throws {
        print("git stash")
    }
}

option

enum Commit: String, Command {

    case message
    case allowEmpty
    
    var shortOption: String? {
        switch self {
        case .message: return "m"
        default:       return nil
        }
    }

    static func run() throws {
        let matchOptions = Commit.matchOptions
        switch matchOptions {
        case _ where matchOptions[.message]:
            print("git commit -m")
        case _ where matchOptions[.allowEmpty, .message]:
            print("git commit --allow-empty -m")
        default: break
        }
    }
}

Analysis method of command options is as follows:

definition	prefix	separator	example word	analyzed
single-word	--		message	--message
multiple-word	--	-	allowEmpty	--allow-empty

        switch self {
        case .commit: try Commit.run()
        case .stash:  try Stash.run()
        }
    }
}

Running

try YourCli().run()
