Method: Bombshell::Shell::ClassMethods#launch

Defined in:
lib/bombshell/shell.rb

#launch(*arguments) ⇒ Object

Launch the shell.

You should generally call Bombshell.launch(MyShell) instead of MyShell.launch directly, as the former approach will handle exits correctly and pass command-line parameters as arguments.

Parameters:

  • arguments (Array) —

    An array of arguments that, eventually, callbacks might use. If you’re using the Bombshell.launch wrapper, these will be command-line parameters.
