Settle

Library which provides a function that waits for something to happen. Usage:

use Keboola\Settle\SettleFactory;
use Psr\Log\NullLogger;

$logger = new NullLogger();
$factory = new SettleFactory($logger);

$settle = $factory->createSettle(maxAttempts: 10, maxAttemptsDelay: 1);
$i = 0;
$settle->settle(
    comparator: fn($v) => $v === 5,
    getCurrentValue: function() use (&$i) {while ($i < 5) {$i++; return $i;}},
);

The settle function expects two callbacks - comparator and getCurrentValue. In a typical scenario, the getCurrentValue checks and returns the result of some asynchronous operation (data loaded, process finished) and the comparator checks that the getCurrentValue result is the expected value. If the expected value is not reached within the specified number of attempts a RuntimeException is thrown.
