Installation

Install the package with Composer:

composer require drevops/tui

The package is a library consumed programmatically - it has no CLI entry point of its own. The public surface is:

  • DrevOps\Tui\Tui - the facade: collect a form's answers, headlessly or through the interactive panel TUI.
  • DrevOps\Tui\Builder\Form - the fluent builder for declaring a form's panels and fields.

Usage​

Declare a form with the fluent Form builder, then drive it with the Tui facade - one class that wires the engine, resolver, schema tools and TUI for you:

use DrevOps\Tui\Builder\Form;
use DrevOps\Tui\Builder\PanelBuilder;
use DrevOps\Tui\Tui;

$form = Form::create('Quick start')
  ->panel('order', 'New order', function (PanelBuilder $p): void {
    // A required single-line text field.
    $p->text('name', 'Order name')->required();

    // A single choice, starting on "Banana".
    $p->select('fruit', 'Fruit')->default('banana')->options([
      'apple' => 'Apple',
      'banana' => 'Banana',
      'cherry' => 'Cherry',
    ]);

    // A multi-select, with one option pre-checked.
    $p->multiSelect('veg', 'Vegetables')->default(['carrot'])->options([
      'carrot' => 'Carrot',
      'tomato' => 'Tomato',
      'spinach' => 'Spinach',
    ]);

    // An integer bounded to a sensible quantity.
    $p->number('quantity', 'Quantity')->min(1)->max(99)->default(6);

    // A yes/no gate.
    $p->confirm('organic', 'Organic only?')->default(FALSE);
  });

$tui = new Tui($form);

// Interactive panel TUI on a terminal, headless otherwise.
$answers = $tui->run();

// Or drive a mode directly:
echo $tui->collect('{"name":"Weekly box"}')->toJson(); // headless: JSON + environment
$answers = $tui->interact();                    // interactive panel TUI

run() picks the mode automatically: it drives the interactive panel TUI on a terminal and collects headlessly otherwise (or whenever prompts are supplied). The facade also exposes schema(), agentHelp() and validate(), and - when you want finer control - the internals via form(), engine() and registry().
