4+
How to Define Commands as Services
5+
==================================
6+
7+
..versionadded::2.4
8+
Support for registering commands in the service container was introduced in
9+
version 2.4.
10+
11+
By default, Symfony will take a look in the ``Command`` directory of each
12+
bundle and automatically register your commands. If a command extends the
13+
:class:`Symfony\\Bundle\\FrameworkBundle\\Command\\ContainerAwareCommand`,
14+
Symfony will even inject the container.
15+
While making life easier, this has some limitations:
16+
17+
* Your command must live in the ``Command`` directory;
18+
* There's no way to conditionally register your service based on the environment
19+
or availability of some dependencies;
20+
* You can't access the container in the ``configure()`` method (because
21+
``setContainer`` hasn't been called yet);
22+
* You can't use the same class to create many commands (i.e. each with
23+
different configuration).
24+
25+
To solve these problems, you can register your command as a service and tag it
26+
with ``console.command``:
27+
28+
..configuration-block::
29+
30+
..code-block::yaml
31+
32+
# app/config/config.yml
33+
services:
34+
acme_hello.command.my_command:
35+
class:Acme\HelloBundle\Command\MyCommand
36+
tags:
37+
-{ name: console.command }
38+
39+
..code-block::xml
40+
41+
<!-- app/config/config.xml-->
42+
<?xml version="1.0" encoding="UTF-8" ?>
43+
<containerxmlns="http://symfony.com/schema/dic/services"
44+
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
45+
xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">
46+
47+
<services>
48+
<serviceid="acme_hello.command.my_command"
49+
class="Acme\HelloBundle\Command\MyCommand">
50+
<tagname="console.command" />
51+
</service>
52+
</services>
53+
</container>
54+
55+
..code-block::php
56+
57+
// app/config/config.php
58+
$container
59+
->register('acme_hello.command.my_command', 'Acme\HelloBundle\Command\MyCommand')
60+
->addTag('console.command')
61+
;
62+
63+
Using Dependencies and Parameters to Set Default Values for Options
64+
-------------------------------------------------------------------
65+
66+
Imagine you want to provide a default value for the ``name`` option. You could
67+
pass one of the following as the 5th argument of ``addOption()``:
68+
69+
* a hardcoded string;
70+
* a container parameter (e.g. something from parameters.yml);
71+
* a value computed by a service (e.g. a repository).
72+
73+
By extending ``ContainerAwareCommand``, only the first is possible, because you
74+
can't access the container inside the ``configure()`` method. Instead, inject
75+
any parameter or service you need into the constructor. For example, suppose you
76+
have some ``NameRepository`` service that you'll use to get your default value::
77+
78+
// src/Acme/DemoBundle/Command/GreetCommand.php
79+
namespace Acme\DemoBundle\Command;
80+
81+
use Acme\DemoBundle\Entity\NameRepository;
82+
use Symfony\Component\Console\Command\Command;
83+
use Symfony\Component\Console\Input\InputInterface;
84+
use Symfony\Component\Console\Input\InputOption;
85+
use Symfony\Component\Console\Output\OutputInterface;
86+
87+
class GreetCommand extends Command
88+
{
89+
protected $nameRepository;
90+
91+
public function __construct(NameRepository $nameRepository)
92+
{
93+
$this->nameRepository = $nameRepository;
94+
}
95+
96+
protected function configure()
97+
{
98+
$defaultName = $this->nameRepository->findLastOne();
99+
100+
$this
101+
->setName('demo:greet')
102+
->setDescription('Greet someone')
103+
->addOption('name', '-n', InputOption::VALUE_REQUIRED, 'Who do you want to greet?', $defaultName)
104+
;
105+
}
106+
107+
protected function execute(InputInterface $input, OutputInterface $output)
108+
{
109+
$name = $input->getOption('name');
110+
111+
$output->writeln($name);
112+
}
113+
}
114+
115+
Now, just update the arguments of your service configuration like normal to
116+
inject the ``NameRepository``. Great, you now have a dynamic default value!
117+
118+
..caution::
119+
120+
Be careful not to actually do any work in ``configure`` (e.g. make database
121+
queries), as your code will be run, even if you're using the console to
122+
execute a different command.

-------------------------------------------

114-
Registering your command asa service gives you more control over its
115-
location and the services that are injected into it. But, there are no
116-
functional advantages, so you don't need to register your command as a service.
70+
Just like controllers, commands can be declared asservices. See the
71+
:doc:`dedicated cookbook entry</cookbook/console/commands_as_services>`
72+
for details.
