Symfony 进度条正在新行上重新创建

Question

Symfony 控制台进度条不是在同一行上前进，而是在新的一行上创建

 1/2 [==============>-------------]  50%
 ! [NOTE] No changes made to Categories/CategoriesSchema              


 2/2 [============================] 100%
 2/2 [============================] 100%

我假设进度条只会在同一行上移动，直到操作完成。这是我的代码

$io = new SymfonyStyle($input, $output);
$progressbar = new ProgressBar($output, count($elements));
$progressbar->start();

foreach ($elements as $element) {

     //work on element
     io->note("No changes made to ".ucfirst($name));

     $progressbar->advance();
     $io->newLine();
}

$progressbar->finish();

我哪里做错了？？

如果进度不是自主的，它将始终在新的一行上，除非您在写入 io 之前将其清除。 [sic]

If you want to output something while the progress bar is running, call clear() first. After you're done, call display() to show the progress bar again.

因此，要么在启动进度条之前写入您的 io。

$io->note('No changes made to ' . ucfirst($name));
$io->newLine();

$progressbar->start();
foreach ($elements as $element) {
    $progressbar->advance();
    sleep(1);
}
$progressbar->finish();

或在写入 io 之前在进度条上调用 clear()，完成后调用 display()。

$progressbar->start();
foreach ($elements as $element) {
    if (true /* put conditional here */) {
        $progressbar->clear(); //remove progress bar from display
        $io->note('No changes made to ' . ucfirst($name));
        $io->newLine();
        $progressbar->display(); //redraw progress bar in display
    }
    $progressbar->advance(); //move up a step
    sleep(1);
}    
$progressbar->finish();
