Cake\Console\ConsoleOptionParser::addArgument()

addOptionsource public

addOption( Cake\Console\ConsoleInputOption|string $name , array $options [] )

Add an option to the option parser. Options allow you to define optional or required parameters for your console application. Options are defined by the parameters they use.

Options

• short - The single letter variant for this option, leave undefined for none.
• help - Help text for this option. Used when generating help for the option.
• default - The default value for this option. Defaults are added into the parsed params when the attached option is not provided or has no value. Using default and boolean together will not work. are added into the parsed parameters when the option is undefined. Defaults to null.
• boolean - The option uses no value, it's just a boolean switch. Defaults to false. If an option is defined as boolean, it will always be added to the parsed params. If no present it will be false, if present it will be true.
• choices A list of valid choices for this option. If left empty all values are valid.. An exception will be raised when parse() encounters an invalid value.

Parameters

Cake\Console\ConsoleInputOption|string $name

The long name you want to the value to be parsed out as when options are parsed. Will also accept an instance of ConsoleInputOption

array $options optional []

An array of parameters that define the behavior of the option

Returns

mixed
$this

addOptionssource public

addOptions( array $options )

Add multiple options at once. Takes an array of option definitions. The keys are used as option names, and the values as params for the option.

Parameters
