Help:
  The swiftmailer:spool:send command sends all emails from the spool.

  php bin/console swiftmailer:spool:send --message-limit=10 --time-limit=10 --recover-timeout=900 --mailer=default

I'd like to run this with debug-level verbosity. However I am getting the exact same output as when I run the command normally:

$ php bin/console swiftmailer:spool:send -vvv

 [2021-10-15 12:11:22] Processing default mailer spool...
 2 emails sent

I would expect verbose option to at least display some details about the message being sent... Does anyone know what kind of output the different verbosity levels are supposed to display? Am I doing using it incorrectly and if so what's the right way to get verbose output?

CodePudding user response：

Verbosity level isn't tied to a specific command. It's a part of symfony/console component and just a way to give you (as developer) controls to react to users' input.

Not all provided commands take an advantage of and do not always react to it. If you look inside Symfony\Bundle\SwiftmailerBundle\Command\SendEmailCommand.php you won't find neither

if($this->io->getVerbosity()) { //... }

nor

if($this->io->isVerbose()) { //... }

nor

if($this->io->isVeryVerbose()) { //... }

So there's simply no logic for -vvv in swiftmailer:spool:send

So in general, higher verbosity will simply give you more information about error, e.g. stack trace if any exception is thrown. ...unless you implemented some checks in your own commands.
