Symfony 7.3 introduces powerful improvements to the Console component, beyond
the much-anticipated invokable commands and input attributes. This version also
brings new helpers and features designed to make console applications more capable.

Markdown Tables

The table helper lets you create complex tables with various structures and
formats. In Symfony 7.3, we've introduced a new style for generating tables in
Markdown format. This is useful, for example, when generating content for
GitHub/GitLab issues, pull requests, CI messages, and more.

use Symfony\Component\Console\Helper\Table;
// ...

$table = new Table($output);
$table
->setHeaders(['Version', 'Release Date', 'Is LTS?'])
->setRows([
['Symfony 7.0', 'November 2023', 'No'],
// ...
['...', '...', '...'],
])
;
$table->setStyle('markdown');
$table->render();

This outputs:

| Version | Release Date | Is LTS? |
|---------------|--------------------------|------------------|
| Symfony 7.0 | November 2023 | No |
| Symfony 7.1 | May 2024 | No |
| Symfony 7.2 | November 2024 | No |
| Symfony 7.3 | May 2025 | No |
| Symfony 7.4 | November 2025 | Yes |

Tree Helper

The Console component includes many helpers for rendering elements like
progress bars and prompts, for controlling the cursor, etc. In Symfony 7.3,
we've added a new helper for rendering tree-like structures.
This helper is typically used to render directory hierarchies but can handle any
tree-like data:

use Symfony\Component\Console\Helper\TreeHelper;
use Symfony\Component\Console\Style\SymfonyStyle;
// ...

$io = new SymfonyStyle($input, $output);
$tree = TreeHelper::createTree($io, null, [
'src' => [
'Command',
'Controller' => [
'DefaultController.php',
],
'Kernel.php',
],
'templates' => [
'base.html.twig',
],
]);
$tree->render();

This outputs:

├── src
│ ├── Command
│ ├── Controller
│ │ └── DefaultController.php
│ └── Kernel.php
└── templates
└── base.html.twig

If you don't know the tree elements beforehand, you can build the tree programmatically:

use Symfony\Component\Console\Helper\TreeNode;
// ...

$node = TreeNode::fromValues(['Command', 'Controller']);
// ...
$node->addChild('templates');
$node->addChild('tests');

The tree helper provides seven built-in styles (box, double, minimal, rounded,
etc.) and lets you create your own tree style.
