single: Console Helpers; Cursor Helper
5.1
The Symfony\\Component\\Console\\Cursor
class was introduced in Symfony 5.1.
The Symfony\\Component\\Console\\Cursor
allows you to change the cursor position in a console command. This allows you to write on any position of the output:
// src/Commande/MyCommand.php
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Cursor;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
class MyCommand extends Command
{
// ...
public function execute(InputInterface $input, OutputInterface $output)
{
// ...
$cursor = new Cursor($output);
// moves the cursor to a specific column and row position
$cursor->moveToPosition(7, 11);
// and write text on this position using the output
$output->write('My text');
// ...
}
}
There are fews methods to control moving the command cursor:
// moves the cursor 1 line up from its current position
$cursor->moveUp();
// moves the cursor 3 lines up from its current position
$cursor->moveUp(3);
// same for down
$cursor->moveDown();
// moves the cursor 1 column right from its current position
$cursor->moveRight();
// moves the cursor 3 columns right from its current position
$cursor->moveRight(3);
// same for left
$cursor->moveLeft();
// move the cursor to a specific position from its current position
$cursor->moveToPosition(7, 11);
You can get the current command's cursor position by using:
$position = $cursor->getCurrentPosition();
// $position[0] // columns (aka x coordinate)
// $position[1] // rows (aka y coordinate)
The cursor can also clear some output on the screen:
// clears all the output from the current line
$cursor->clearLine();
// clears all the output from the current line after the current position
$cursor->clearLineAfter();
// clears all the output from the cursors' current position to the end of the screen
$cursor->clearOutput();
// clears the entire screen
$cursor->clearScreen();
You also can leverage the Symfony\\Component\\Console\\Cursor::show
and Symfony\\Component\\Console\\Cursor::hide
methods on the cursor.
