The <info>%command.name%</info> command displays all configured <comment>public</comment> services:
|
|
|
|
<info>php %command.full_name%</info>
|
|
|
|
To get specific information about a service, specify its name:
|
|
|
|
<info>php %command.full_name% validator</info>
|
|
|
|
To see available types that can be used for autowiring, use the <info>--types</info> flag:
|
|
|
|
<info>php %command.full_name% --types</info>
|
|
|
|
By default, private services are hidden. You can display all services by
|
|
using the <info>--show-private</info> flag:
|
|
|
|
<info>php %command.full_name% --show-private</info>
|
|
|
|
Use the --tags option to display tagged <comment>public</comment> services grouped by tag:
|
|
|
|
<info>php %command.full_name% --tags</info>
|
|
|
|
Find all services with a specific tag by specifying the tag name with the <info>--tag</info> option:
|
|
|
|
<info>php %command.full_name% --tag=form.type</info>
|
|
|
|
Use the <info>--parameters</info> option to display all parameters:
|
|
|
|
<info>php %command.full_name% --parameters</info>
|
|
|
|
Display a specific parameter by specifying its name with the <info>--parameter</info> option:
|
|
|
|
<info>php %command.full_name% --parameter=kernel.debug</info>
