Invokable command loader#62311

I have been lately usinginvokable commands in mysymfony/console applications, and it works great. It's a very good approach, and I plan to bet further on this onceSymfony 7.4 is released.

The only limitation I have found so far is that I'm using theContainerCommandLoader to dynamically load my commands from a container, but since theget method has aCommand return type, I need to make my invokable commands extend fromCommand even if I'm not using any of its methods.

I wanted to know if there are any plans to provide alternative ways to lazy-load commands without having to extendCommand.

Hey@acelaya, just wondering what kind of error you're seeing in this case..

when an invokable command is defined without extendingCommand, it's automatically wrapped into aCommand instance during the compiler pass, so retrieving it through theContainerCommandLoader should still return a validCommand instance.

since 7.4, you can also get the invokable command class usingCommand::getCode().

I'm assuming this happens when using Symfony's default dependency injection container? I'm using a different PSR-11 container, so I guess that's the reason.

I basically get a runtimeTypeError because theget method expects aCommand to be returned, but calling$this->container->get($this->commandMap[$name]); doesn't do that in my case.

TypeError: Symfony\Component\Console\CommandLoader\ContainerCommandLoader::get(): Return value must be of type Symfony\Component\Console\Command\Command, Shlinkio\Shlink\CLI\Command\Api\InitialApiKeyCommand returned in /home/shlink/vendor/symfony/console/CommandLoader/ContainerCommandLoader.php on line 40

Could you point me to the place where this wrapping is done? I might be able to implement a small piece of logic doing something similar by implementing a custom command loader.

Yes, everything is in AddConsoleCommandPass
