Wouldn't it make more sense to show the full template of the autoconfigure? Autoconfigure works based on an interface(/class?), thus it would make sense to see what other configuration is being added by this.

Sorry, I don't understand. What is the the full template of the autoconfigure ? Do you propose to display like this:

    _instanceof:        Symfony\Component\Security\Core\Authorization\Voter\VoterInterface:            tags: [security.voter]

or do you propose to display like the output of the commandphp ./bin/console debug:container App\\Security\\PostVoter with the information of autoconfigure ?

Information for Service "App\Security\PostVoter"================================================ ---------------- ------------------------   Option           Value                    ---------------- ------------------------   Service ID       App\Security\PostVoter    Class            App\Security\PostVoter    Tags             security.voter            Public           no                        Synthetic        no                        Lazy             no                        Shared           yes                       Abstract         no                        Autowired        yes                       Autoconfigured   yes                       Autoconfigure class Symfony\Component\Security\Core\Authorization\Voter\VoterInterface  Autoconfigure tag security.voter ---------------- ------------------------

What about something like this?

Autoconfiguration for "Symfony\Component\Security\Core\Authorization\Voter\VoterInterface"================================================ ---------------- ------------------------   Option           Value                    ---------------- ------------------------   Tags             security.voter  Public           no  Any other options and values etc. ---------------- ------------------------

The command would have been useful to me during a migration of a project to the autowiring/autoconfigure.

Every time, I wondered if I could delete the configuration or not in services.yaml to reduce its size.

The command allows to know the autonconfiguring tags.
Which interface/class should be implemented to have autoconfiguration applied ?

If there is a need to know the full template, the commanddebug:container App\\Security\\PostVoter can be used. I have not yet meet the need to have the full template of the autoconfigure.

I really think such a command is a nice addition.
@iltar's comment is relevant especially now that autoconfiguration works for function calls (see#26768).

Maybe a separate command could be worth it?debug:autoconfiguration
by default it could display as@iltar suggests, and when the--tags is passed, be grouped by tags?

rebase needed (needs to account for the new show-hidden option)

@nicolas-grekas I create the separate command in#28730

Closing in favor of#28730
