Details

static string|null getDefaultName()

Return Value

string|null The default command name or null when no default name is set

__construct(string $documentRoot = null, string $environment = null)

Parameters

string $documentRoot
string $environment

Exceptions

LogicException When the command name is empty

ignoreValidationErrors()

Ignores validation errors.

This is mainly useful for the help command.

setApplication(Application $application = null)

Parameters

Application $application

setHelperSet(HelperSet $helperSet)

Parameters

HelperSet $helperSet

HelperSet getHelperSet()

Gets the helper set.

Return Value

HelperSet A HelperSet instance

Application getApplication()

Gets the application instance for this command.

Return Value

Application An Application instance

bool isEnabled()

Checks whether the command is enabled or not in the current environment.

Override this to check for x or y and return false if the command can not run properly under the current conditions.

Return Value

bool

protected configure()

Configures the current command.

protected int|null execute(InputInterface $input, OutputInterface $output)

Executes the current command.

This method is not abstract because you can use this class as a concrete class. In this case, instead of defining the execute() method, you set the code to execute by passing a Closure to the setCode() method.

Parameters

InputInterface $input
OutputInterface $output

Return Value

int|null null or 0 if everything went fine, or an error code

Exceptions

LogicException When this abstract method is not implemented

protected interact(InputInterface $input, OutputInterface $output)

Interacts with the user.

This method is executed before the InputDefinition is validated. This means that this is the only place where the command can interactively ask for values of missing required arguments.

Parameters

InputInterface $input
OutputInterface $output

protected initialize(InputInterface $input, OutputInterface $output)

Initializes the command after the input has been bound and before the input is validated.

This is mainly useful when a lot of commands extends one main command where some things need to be initialized based on the input arguments and options.

Parameters

InputInterface $input
OutputInterface $output

See also

int run(InputInterface $input, OutputInterface $output)

Runs the command.

The code to execute is either defined directly with the setCode() method or by overriding the execute() method in a sub-class.

Parameters

InputInterface $input
OutputInterface $output

Return Value

int The command exit code

Exceptions

Exception When binding input fails. Bypass this by calling {@link ignoreValidationErrors()}.

See also

$this setCode(callable $code)

Sets the code to execute when running this command.

If this method is used, it overrides the code defined in the execute() method.

Parameters

callable $code A callable(InputInterface $input, OutputInterface $output)

Return Value

$this

Exceptions

InvalidArgumentException

See also

mergeApplicationDefinition(bool $mergeArgs = true)

Merges the application definition with the command definition.

This method is not part of public API and should not be used directly.

Parameters

bool $mergeArgs Whether to merge or not the Application definition arguments to Command definition arguments

$this setDefinition(array|InputDefinition $definition)

Sets an array of argument and option instances.

Parameters

array|InputDefinition $definition An array of argument and option instances or a definition instance

Return Value

$this

InputDefinition getDefinition()

Gets the InputDefinition attached to this Command.

Return Value

InputDefinition An InputDefinition instance

InputDefinition getNativeDefinition()

Gets the InputDefinition to be used to create representations of this Command.

Can be overridden to provide the original command representation when it would otherwise be changed by merging with the application InputDefinition.

This method is not part of public API and should not be used directly.

Return Value

InputDefinition An InputDefinition instance

$this addArgument(string $name, int|null $mode = null, string $description = '', string|string[]|null $default = null)
