TaskIO
trait TaskIO (View source)
Task input/output methods. TaskIO is 'used' in BaseTask, so any task that extends this class has access to all of the methods here.
printTaskInfo, printTaskSuccess, and printTaskError are the three primary output methods that tasks are encouraged to use. Tasks should avoid using the IO trait output methods.

Methods
Any class that uses ConfigAwareTrait SHOULD override this method , and define a prefix for its configuration items. This is usually done in a base class. When used, this method should return a string that ends with a "."; see BaseTask::configPrefix().

printTaskInfo(string $text, null|array $context = null)
Print information about a task in progress.
With the Symfony Console logger, NOTICE is displayed at VERBOSITY_VERBOSE and INFO is displayed at VERBOSITY_VERY_VERBOSE.
Robo overrides the default such that NOTICE is displayed at VERBOSITY_NORMAL and INFO is displayed at VERBOSITY_VERBOSE.
n.b. We should probably have printTaskNotice for our ordinary output, and use printTaskInfo for less interesting messages.
protected
printTaskSuccess(string $text, null|array $context = null)
Provide notification that some part of the task succeeded.
With the Symfony Console logger, success messages are remapped to NOTICE, and displayed in VERBOSITY_VERBOSE. When used with the Robo logger, success messages are displayed at VERBOSITY_NORMAL.
protected
printTaskWarning(string $text, null|array $context = null)
Provide notification that there is something wrong, but execution can continue.
Warning messages are displayed at VERBOSITY_NORMAL.
protected
printTaskError(string $text, null|array $context = null)
Provide notification that some operation in the task failed, and the task cannot continue.
Error messages are displayed at VERBOSITY_NORMAL.
protected
printTaskDebug($text, null|array $context = null)
Provide debugging notification. These messages are only displayed if the log level is VERBOSITY_DEBUG.

getPrintedTaskName(null|object $task = null)

This is placed in the task context under 'name', and used as the log label by Robo\Common\RoboLogStyle, which is inserted at the head of log messages by Robo\Common\CustomLogStyle::formatMessage().
