CHANGELOG

This project follows semantic versioning. While still in major version 0, source-stability is only guaranteed within minor versions (e.g. between 0.0.3 and 0.0.4). If you want to guard against potentially source-breaking package updates, you can specify your package dependency using .upToNextMinor(from: "0.0.1") as the requirement.

Unreleased

No changes yet.

0.0.2 - 2020-03-06

Additions

  • The EX_USAGE exit code is now used for validation errors.
  • The parser provides near-miss suggestions when a user provides an unknown option.
  • ArgumentParser now builds on Windows.
  • You can throw an ExitCode error to exit without printing any output.
  • You can now create optional Boolean flags with inversions that default to nil: 
    @Flag(inversion: .prefixedNo) var takeMyShot: Bool?
  • You can now specify exclusivity for case-iterable flags and for Boolean flags with inversions.

Fixes

  • Cleaned up a wide variety of documentation typos and shortcomings.
  • Improved different kinds of error messages:
    • Duplicate exclusive flags now show the duplicated arguments.
    • Subcommand validation errors print the correct usage string.
  • In the help screen:
    • Removed the extra space before the default value for arguments without descriptions.
    • Removed the default value note when the default value is an empty string.
    • Default values are now shown for Boolean options.
    • Case-iterable flags are now grouped correctly.
    • Case-iterable flags with default values now show the default value.
    • Arguments from parent commands that are included via @OptionGroup in subcommands are no longer duplicated.
  • Case-iterable flags created with the .chooseFirst exclusivity parameter now correctly ignore additional flags.
