Module: Omnizip::Shared::HelpDispatch

Included in:
ArchiveCommands, Cli, ProfileCommands
Defined in:
lib/omnizip/cli.rb

Overview

Thor 1.x does not treat --help/-h on subcommands as a request for help: the flag reaches the command as a positional argument and arity checking fails. Classes extending this module route those flags to the standard help output instead.
