I would like to display processing progress using a simple series of dots. This is easy in the browser, just do echo '.' and it goes on the same line, but how do I do this on the same line when sending data to the artisan commandline?
Each subsequent call to $this->info('.') puts the dot on a new line.
The method info uses writeln, it adds a newline at the end, you need to use write instead.
//in your command
$this->output->write('my inline message', false);
$this->output->write('my inline message continues', false);
$this->command->getOutput()->write(//... inside of a seederProbably a little bit of topic, since you want a series of dots only. But you can easily present a progress bar in artisan commands using built in functionality in Laravel.
Declare a class variable like this:
protected $progressbar;
And initialize the progress bar like this, lets say in fire() method:
$this->progressbar = $this->getHelperSet()->get('progress');
$this->progressbar->start($this->output, Model::count());
And then do something like this:
foreach (Model::all() as $instance)
{
$this->progressbar->advance(); //do stuff before or after this
}
And finilize the progress when done by calling this:
$this->progressbar->finish();
Update: For Laravel 5.1+ The simpler syntax is even more convenient:
$bar = $this->output->createProgressBar(count($foo));$bar->advance();$bar->finish();
$this->error(), that will not disrupt the progressbar?
new \Symfony\Component\Console\Helper\ProgressBar($this->output)
If you look at the source, you will see that $this->info is actually just a shortcut for $this->output->writeln: Source.
You could use $this->output->write('<info>.</info>') to make it inline.
If you find yourself using this often you can make your own helper method like:
public function inlineInfo($string)
{
$this->output->write("<info>$string</info>");
}
\r is Carriage return
\n is Newline
So you can use:
echo "something\r";
to write in same line to display progress, for example. After that you can call "\n|
