Hi Dmitry, In my mind, annotation syntax was one level lower, dealing with strings of unknown syntax, not PHP expressions. Something like : '*' '@' STRING free-string-up-to-eol This supports : * @requires $a > 0 But also : * @statement INSERT INTO ?? VALUES (13, 'Phoenix', 'AZ', 33, 112) U

this will work, of course, and robust implementation wouldn't take more than a day :) but it'll require user-level parser again. no big advantage in comparison to doc-block. Thanks. Dmitry. On Mon, Feb 16, 2015 at 6:41 PM, Rowan Collins wrote: > Nikita Popov wrote on 16/02/2015 12:14: > >> I

[PHP-DEV] Re: Annotations in PHP7

The implementation is not going to be simple, and taking in account other tasks, it may be difficult to provide high-quality implementation. Lets look if it's really a desirable feature. Then I may do all my best, or forget about it by 7.1. Thanks. Dmitry. On Mon, Feb 16, 2015 at 3:14 PM, Nikita

Re: [PHP-DEV] Re: Annotations in PHP7

you already have doc-block. nothing should be done in PHP core, but you have to parse it yourself. The goal of annotations is to provide standard and powerful way. On the other hand standard PHP expression syntax may be not enough for all cases. Thanks. Dmitry. On Mon, Feb 16, 2015 at 2:22 PM, Ce

I decided to explain the proposed annotation syntax "in words" to avoid misunderstanding annotations ::= { annotation }. annotation ::= '<' STRING '>' | '<' STRING '(' expr ')' '>'. where is regular PHP expression. Thanks. Dmitry. On Mon, Feb 16, 2015 at 2:07 PM, Dmitry Stogov wrote: > hi
