ArgumentParser 0.0.6

Additions

• Command definition validation now checks for name collisions between options
  and flags.
• ValidationError.message is now publicly accessible.
• Added an EnumerableFlag protocol for CaseIterable types that are used to
  provide the names for flags. When declaring conformance to EnumerableFlag,
  you can override the name specification and help text for individual flags.
  See #65 for more detail.
• When a command that requires arguments is called with no arguments at all,
  the error message includes the full help text instead of the short usage
  string. This is intended to provide a better experience for first-time users.
• Added a helpMessage() method for generating the help text for a command
  or subcommand.

Deprecations

• @Flag properties that use CaseIterable/String types as their values
  are deprecated, and the related @Flag initializers will be removed
  in a future version.

  Migration: Add EnumerableFlag conformance to the type of these kinds of
  @Flag properties.

Fixes

• Errors thrown while parsing in a transform closure are printed correclty
  instead of a general Invalid state error.
• Improvements to the guides and in the error message when attempting to access
  a value from an argument/option/flag definition.
• Fixed issues in the CMake and Windows build configurations.
• You can now use an = to join a value with an option's short name when calling
  a command. This previously only worked for long names.
