Re: Annotations in PHP7

Hi Dmitry, > Are you (and Doctrine team) interested in this annotation idea? I'd say that Benjamin nailed in our possible usage: <orm(new Entity("foo"))> class Foo { } Now I do feel we need to elaborate some sort of named parameters. Doctrine tries to simplify a lot developer's life by using consistency in default mapping and only if the user wants to override default behavior he needs to override a given parameter. This means in a case where you're mapping a JoinColumn ( https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/Mapping/JoinColumn.php ), you may only want to specify the onDelete="CASCADE" operation instead of name, referencedColumnName and many other parameters. Trying to map this in your default parameter passing, we'd have something like: <orm( [ new OneToOne("Address"), new JoinColumn(default, default, default, default, "CASCADE") ] )> public $address; As I said, named parameters make a lot of sense when mapping defaults. Now by looking at this syntax, I still think we're closer to a simple array implementation (ReflectionClass::getMetadata(string $name)) and having something like: <[ "orm" => [ new OneToOne("Address"), new JoinColumn(default, default, default, default, "CASCADE") ] ]> public $address; PS: We haven't even started on talking about overrides yet... =\ Regards, On Wed, Feb 18, 2015 at 12:04 PM, Dmitry Stogov <dmitry@zend.com> wrote: > > > On Wed, Feb 18, 2015 at 6:14 PM, François Laupretre <francois@php.net> > wrote: > >> Hi Dmitry, >> >> >> >> Right.
