The command lists all built-in types, services types, type extensions and
guessers currently available.
<info>php %command.full_name% Symfony\Component\Form\Extension\Core\Type\ChoiceType</info>
<info>php %command.full_name% ChoiceType</info>
The command lists all defined options that contains the given form type,
as well as their parents and type extensions.
<info>php %command.full_name% ChoiceType choice_value</info>
Use the <info>--show-deprecated</info> option to display form types with
deprecated options or the deprecated options of the given form type:
<info>php %command.full_name% --show-deprecated</info>
<info>php %command.full_name% ChoiceType --show-deprecated</info>
The command displays the definition of the given option name.
<info>php %command.full_name% --format=json</info>
The command lists everything in a machine readable json format.
