Aware.
Enough of the complexity is already the responsibility of the consumerof the attributes.
It's already possible to get strings (and so AST) from doc comments,we don't need anything new if that's all you want to do.
Essentially, moving something from doc comments to <<here>> makes zerosense to me.

Except the fact, that doc-comment content don't have to conform to anyrules, and you have to parse it and extract the necessary part of metainformation every time you need it. It's not a big problem to do thisusing Doctrine library, but how are you going to do this in a compiler hook?


Cheers

    You're not really suggesting that I write my tools in user land,
    are you ? It's me, Joe :)ce


    At first days of RFC discussion Sara pointed on over-design
    regarding AST.
    I saw sense in here comments and updated RFC.


    I *only* want attributes as they were originally proposed, and I
    can't vote to reflect that.

    As discussed in private, what I want is attributes, as originally
    proposed, and a hookable compiler; Anything else is not good enough.


    Personally, I'm for AST as well, but it's possible to get the same
    power translating string values of attributes into AST in the hooks.

    Thanks. Dmitry.


    Cheers
    Joe

        Hi Joe,


        The sense in native support for AST is questionable.


        On one hand this allows syntax verification.


        On the other hand simple string may be parsed into AST with
        just one additional call to ast\compile_string().


        Thanks. Dmitry.

        Morning Dmitry,

            I'm not really happy with the voting options here.

            I would not vote in favour of a patch that does not
        include support for AST, that's a completely different feature.

            As it is, I have to vote yes in favour of AST, but it may
        be counted as a vote in favour of attributes without AST ...

            This doesn't seem right ... I don't want attributes
        without AST, and there is no voting option to reflect that.

        Cheers
        Joe

                        Hi internals,


                        I've started voting on "PHP Attributes" RFC.


                        https://wiki.php.net/rfc/attributes


                        In my opinion, "PHP Attributes" might be a
                        smart tool for PHP extension, but it's not
                        going to be the end of the world, if we
                        decided to live with doc-comments only.


                        Thanks. Dmitry.

                    Thanks for the good work. Regarding naming, I googled
                    "PHP attributes" vs "PHP annotations" and looking
                    at the
                    result, my view is that that Annotation is a
                    better naming
                    then Attributes. Any hope in changing it?


                The more I listen to arguments of adepts of existing
                PHP annotation systems, the more I think, that "PHP
                attributes" is the right name for this proposal.
                This feature is not just for PHP annotation systems.


            Thats a fair point, so Annotation it's not. Still, when I
            hear PHP
            attributes I associate it with class / function
            attributes. Maybe
            just a question getting used to the naming. Hm, wonder if PHP
            directives could have been an option?
