Extra TUI widgets and data-source abstractions for symfony/tui — the terminal UI component shipping in Symfony 8.1.

Status: 0.1 — beta. Tracks symfony/tui ^8.1 which is itself experimental. Widgets are usable and the file browser works end-to-end. APIs may shift before 1.0.

What's in the box

Widgets

Data sources (TuiTableSourceInterface)

Syntax highlighting (SyntaxHighlighter)

• Uses bat/batcat if installed (200+ languages, themes)
• PHP fallback via token_get_all() — zero extra deps
• JSON fallback via stdlib pretty-print + hand-rolled tokenizer
• Markdown via MarkdownWidget (league/commonmark + tempest/highlight)

Requirements

• PHP 8.1+
• symfony/tui ^8.1 (currently 8.1.x-dev)
• league/commonmark ^2.0 (for Markdown rendering)
• tempest/highlight ^2.0 (for code blocks within Markdown)

Installation

composer require survos/tui-extras-bundle

Register in your config/bundles.php (or let Flex do it):

Survos\TuiExtrasBundle\SurvosTuiExtrasBundle::class => ['all' => true],

HTTP-less apps (AbstractKernel + KernelTrait + ConsoleBundle, no FrameworkBundle): the bundle works without an HTTP kernel. See the demo/ directory for a minimal setup.

The file browser

The fastest way to see the bundle in action:

cd demo/
composer install
php bin/console browse:files          # tree of current directory
php bin/console browse:files ../src   # browse the bundle source
php bin/console browse:files . --pre-expand=2   # open 2 levels on start
php bin/console browse:files . --raw            # no syntax highlighting
php bin/console browse:files . --no-gitignore   # include ignored files

                                │   * lines compatible with DetailPanelWidget.

Keybindings:

Preview updates instantly as you navigate — no Enter required for files. PHP and JSON files are syntax-highlighted. Markdown files render with full formatting.

FTS5 full-text search demo

php bin/console browse:functions    # ~1300 PHP internal functions, SQLite FTS5

Type / then str_ to filter to all string functions instantly. Uses an in-memory SQLite database with an FTS5 virtual table — the same pattern FolioRowTableSource uses in survos/folio-bundle.

Building a split-pane browser

use Survos\TuiExtrasBundle\Model\TreeNode;
use Survos\TuiExtrasBundle\Widget\DetailPanelWidget;
use Survos\TuiExtrasBundle\Widget\TreeWidget;
use Symfony\Component\Tui\Style\Direction;
use Symfony\Component\Tui\Style\Style;
use Symfony\Component\Tui\Style\StyleSheet;
use Symfony\Component\Tui\Tui;
use Symfony\Component\Tui\Widget\ContainerWidget;

$tree = new TreeWidget();
$tree->addRoot(TreeNode::branch('src/', null, true)
    ->addChild(TreeNode::leaf('Kernel.php', 'src/Kernel.php'))
    ->addChild(TreeNode::branch('Command/')
        ->addChild(TreeNode::leaf('MyCommand.php', 'src/Command/MyCommand.php'))
    )
);

$detail = new DetailPanelWidget();
$tree->onCursorChange(fn($e) => $detail->setContent(
    file_get_contents($e->node->data ?? ''),
    (string) $e->node->data,
));

$split = (new ContainerWidget())->setStyle(new Style(direction: Direction::Horizontal, gap: 1));
$split->add($tree->setStyle(new Style(maxColumns: 40)));
$split->add($detail);

$tui = new Tui(new StyleSheet());
$tui->add($split);
$tui->setFocus($tree);
$tui->run();

Building a DataTable with SQLite FTS5

use Survos\TuiExtrasBundle\Model\TuiColumn;
use Survos\TuiExtrasBundle\Source\SqliteTableSource;
use Survos\TuiExtrasBundle\Widget\DataTableWidget;

$pdo = new \PDO('sqlite:/path/to/data.sqlite');

// FTS5 virtual table: CREATE VIRTUAL TABLE fts_items USING fts5(name, description, content=items, content_rowid=id)
$source = new SqliteTableSource(
    pdo: $pdo,
    table: 'items',
    ftsTable: 'fts_items',
    columns: [
        new TuiColumn(key: 'name', label: 'Name', sortable: true, searchable: true),
        new TuiColumn(key: 'description', label: 'Description', searchable: true),
        new TuiColumn(key: 'created_at', label: 'Created', width: 12, format: 'date', sortable: true),
    ],
);

$table = new DataTableWidget($source);
// Press / to search with FTS5, ↑↓ navigate, s sort, q quit

TuiTableSourceInterface

Implement this to make any data source browsable:

interface TuiTableSourceInterface {
    /** @return TuiColumn[] */
    public function columns(): array;
    public function count(?string $search = null): int;
    /** @return iterable<array<string,mixed>> */
    public function rows(int $offset = 0, int $limit = 25, ?string $search = null, ?string $sortBy = null, string $sortDir = 'ASC'): iterable;
}

Built-in implementations: ArrayTableSource, SqliteTableSource, FileSource. Adapters in other bundles: FolioRowTableSource (survos/folio-bundle), JsonlTableSource (survos/jsonl-bundle, planned).

Roadmap

• browse:commands — vendor/bin/browse command browser (tree of namespaces + full --help in detail pane)
• FolioRowTableSource — FTS5-backed browser for survos/folio-bundle
• MeilisearchTableSource + browse:meili — live Meilisearch browser
• Generic SQLite schema browser (squall-style: table tree + row DataTable)
• PHAR packaging via humbug/box (vendor/bin/browse)
