Usage examples

[DWMcload]

Hi there,

I was looking for more in-depth documentation, a wiki page, or other usage examples. I've searched StackOverflow for the bundle's name and looked at closed issues, but I couldn't find any more help on how to use this package apart from the seemingly old screenshot included in the readme.
I come from a Laravel background and my goal is to find a suitable alternative for Laravel artisan tinker in Symfony.

How can I access my application's code in PsyshBundle?
Here are my tries in the console. I obviously have a User entity and plenty of repositories, but it seems I cannot access or even locate them. Could you please help me with some configuration and usage examples?

bin/console psysh

I obviously have a User entity and plenty of repositories

But your user entity classname is probably not \User but App\Entity\User or something.

Laravel tinker extends psysh a bit to provide those sort of aliases but it was not clear to me how it was done so I never really found a way to implement this. I also wish the laravel team would try to contribute to tab completion support which I think would help a lot there but unfortunately there was never any interest in it.
