Symfony config.yml - How to pass constructor arguments by name?
To be honest I never saw injecting arguments using keys.I know you can use keys when dealing with parameters or when injecting using setters, like the documentation says:http://symfony.com/doc/current/book/service_container.html#optional-dependencies-setter-injection
If you want to inject using setters you could do:
//config.ymlservices: some.service.name: class: SomeClass calls: - [setFormat, "[%%datetime%%] %%channel%%.%%level_name%%"]But the Monolog LineFormatter doesn't support that.
In the end I think you will go for the common array mode.
I hope this helps, if you have some docs showing examples using keys I would like to see that and then we can discuss it!
