어떤 프로젝트인가요?

Swift Argument Parser is a library for building command-line tools in Swift. You declare a type whose stored properties are annotated with property wrappers for flags, options, and positional arguments, then conform it to ParsableCommand or AsyncParsableCommand. The library parses the arguments, instantiates your type, and runs your run() method, or exits with an error message.

Because the parser uses property names, types, and the help text you supply, it generates usage lines, detailed --help output, and error messages without extra code. Commands can be nested into subcommands, and the package includes examples such as a nested math tool and an async/await line counter.

The package follows semantic versioning and requires a minimum Swift toolchain that depends on the release, from Swift 5.1 for early versions up to Swift 6.0 for 1.8.0 and later.

핵심 기능

  • 01Declare flags, options, and positional arguments with property wrappers.
  • 02Generates usage text, detailed help, and error messages automatically.
  • 03Supports nested commands and subcommands.
  • 04Offers async/await support through AsyncParsableCommand.
  • 05Integrates with Swift Package Manager as a dependency.

활용 사례

  • Building a command-line tool in Swift or on Apple platforms.
  • Adding a structured subcommand hierarchy to an existing Swift CLI.
  • Writing a quick script-style utility that needs typed argument parsing.
