Feature: #59606 - Integrate Symfony/Console into CommandController
==================================================================
See :issue:`59606`
Description
===========
The CommandController now makes use of Symfony/Console internally and
provides various methods directly from the CommandController's `output` member:
* TableHelper
* outputTable($rows, $headers = NULL)
* DialogHelper
* select($question, $choices, $default = NULL, $multiSelect = false, $attempts = FALSE)
* ask($question, $default = NULL, array $autocomplete = array())
* askConfirmation($question, $default = TRUE)
* askHiddenResponse($question, $fallback = TRUE)
* askAndValidate($question, $validator, $attempts = FALSE, $default = NULL, array $autocomplete = NULL)
* askHiddenResponseAndValidate($question, $validator, $attempts = FALSE, $fallback = TRUE)
* ProgressHelper
* progressStart($max = NULL)
* progressSet($current)
* progressAdvance($step = 1)
* progressFinish()
Here's an example showing of some of those functions:
.. code-block:: php
namespace Acme\Demo\Command;
use TYPO3\CMS\Extbase\Mvc\Controller\CommandController;
/**
* My command
*/
class MyCommandController extends CommandController {
/**
* @return string
*/
public function myCommand() {
// render a table
$this->output->outputTable(array(
array('Bob', 34, 'm'),
array('Sally', 21, 'f'),
array('Blake', 56, 'm')
),
array('Name', 'Age', 'Gender'));
// select
$colors = array('red', 'blue', 'yellow');
$selectedColorIndex = $this->output->select('Please select one color', $colors, 'red');
$this->outputLine('You choose the color %s.', array($colors[$selectedColorIndex]));
// ask
$name = $this->output->ask('What is your name?' . PHP_EOL, 'Bob', array('Bob', 'Sally', 'Blake'));
$this->outputLine('Hello %s.', array($name));
// prompt
$likesDogs = $this->output->askConfirmation('Do you like dogs?');
if ($likesDogs) {
$this->outputLine('You do like dogs!');
}
// progress
$this->output->progressStart(600);
for ($i = 0; $i < 300; $i ++) {
$this->output->progressAdvance();
usleep(5000);
}
$this->output->progressFinish();
}
}
Impact
======
This change does not alter the public API so it is not breaking
in the strict sense. But it introduces a new behavior:
Previously all output was collected in the `Cli\Response` and only rendered to the console at the end of a CLI request.
Now all methods producing output (including `output()` and `outputLine()`) render the result directly to the console.
If you use `$this->response` directly or let the command method return a string, the rendering is still deferred until
the end of the CLI request.
