ArgumentParser 1.4.0

on GitHub

Additions

• Adds support for subcommand aliases via a new CommandConfiguration.aliases parameter. Aliases are shown in help text and used during command parsing. For example, a subcommand like "average" from the example "math" tool can be defined with the aliases ["avg"]. The resulting subcommand can now be invoked with either of math stats average and ``math stats avg`. See the updated documentation and example for additional details. (#627)
• Adds a new API usageString to ParsableArguments and ParsableCommand for retrieving their usage text, allowing for more flexible construction of error screens. (#634)
• Adds support for passing custom arguments to AsyncParsableCommand.main() with a new static func main(_ arguments: [String]?) async method. (#568)

Fixes

• Removes default parameter values from deprecated CommandConfiguration initializers to prevent them from being selected as overloads. Some niche invalid deprecation warnings should no longer occur. (#636)
