Link copied to clipboard

If true, don't display this command in help output when used as a subcommand.

Link copied to clipboard

Used when this command has subcommands, and this command is called without a subcommand. If true, run will be called. By default, a PrintHelpMessage is thrown instead.

If this command is called with no values on the command line, print a help message (by throwing PrintHelpMessage) if this is true, otherwise run normally.

If true, any options on the command line whose names aren't valid will be parsed as an argument rather than reporting an error. You'll need to define an argument().multiple() to collect these options, or an error will still be reported. Unknown short option flags grouped with other flags on the command line will always be reported as errors.
