Added support for multiple text style options

Contributed by

SpacePossum in #19495 .

The output of the console commands can use any ofthese text styles to change its appearance: bold , underscore , blink , reverse and conceal . In Symfony 3.2, you can combine more than one text style for a single content (for example to display some text bold and underscored):

$output->writeln('<fg=green;options=bold,underscore>Test</>');

In any case, remember that Symfony provides a simpler way toapply the same style to your console commands in a consistent way.

Added support for private commands

Contributed by

Jordan Deitch in #20029 .

By default Symfony commands are public, so they are always included in the command listings displayed when running bin/console or bin/console list . In Symfony 3.2, you can remove some commands from those listings making them private with the setPublic(false) method:

// src/AppBundle/Command/FooCommand.php namespace AppBundle\Command; use Symfony\Component\Console\Command\Command; class FooCommand extends Command { protected function configure() { $this ->setName('app:foo') // ... ->setPublic(false) ; } }

Private commands behave the same as public commands and they can be executed as before, but they are no longer displayed in command listings, so end-users are not aware of their existence. They are best suited for commands designed for the legacy parts of the application, for commands exclusively executed through scheduled tasks, etc.
