Progress Output

CLIFramework has built-in support for progress bars. Start by creating an instance from CLIFramework\ProgressBar. You'll need an output stream, like the STDERR or STDOUT global constants and a CLIFramework\ServiceContainer which you can get from the getService() method on application. Inside a command you can use $this->getApplication()->getService().

Indicate the start of the process by calling setUnit($unit) and start($title). Then indicate updates by optionally calling setTitle($title) before updateLayout() and update($finished, $total). End the process by calling finish($title).

See the example below:

$progress = new CLIFramework\Component\Progress\ProgressBar(STDOUT);
$progress->setUnit('bytes');
$progress->start('downloading file');
$total = 512;
for ($i = 0; $i <= $total; $i++) {
    usleep(5 * 10000); //Simulate downloading file.
    $progress->updateLayout();
    $progress->update($i, $total);
}
$progress->finish();
