php-generics VS php-generics-rfc

Hi. I'm the author of the library which brings generics into PHP like TypeScript https://github.com/mrsuh/php-generics. Libraries like this have a few big problems to start using them freely:

I used this knowledge to create the PHP generics library.

Hi! I don't think so. Is used this library to translate generics syntax into regular PHP syntax. It's not equal to real PHP generics (like Hack did). IDE doesn't support PHP generic syntax yet. You can read about it here.

If you are only using simple collections you can use array - it is very fast and requires little memory. PHP doesn't support generic syntax and IDE can't make hints about the type of objects in a collection (yet), but if you want PHP to do type checks at runtime you can test the php-generics library.

A few months ago I created a PHP generics library with monomorphic generics. Today I released version 1.2.0 with type erase generics.

This approach has a big memory effect. PHP doesn't support native generics, but you can test monomorphized generics with my library.

About generics: it's very hard.

Nikita wrote a good summary about the topic and, even if we go with type erased, there still the syntax problem to solve.

Ok) I wrote at the very beginning of the post which collections I will compare. There you can find links to the generics library. I will be very happy when the PHP IDE add support of generics, but the PHP community hasn't decided what the syntax will be. If you can help with this please let me know.

Nikic did a POC about generics a couple years ago and raised some concerns. The first one was performance, if types were to be validated on runtime, and the other was (as always in PHP...) syntax ambiguities, wich could require to use a new parser.

This approach has a small performance/memory effect. Nikita Popov already had an attempt to implement this type of generics in PHP.

Doesn't support generic syntax because of RFC is not complete yet.

I was reading some stuff and found some discussion going here: https://github.com/PHPGenerics/php-generics-rfc/issues/45

I assume familiarising yourself on the existing discussions on GitHub and the internals mailing list would be a start to understand what the issue with implementing them is, and why the delay for a real implementation. Nikita made some useful notes here: https://github.com/PHPGenerics/php-generics-rfc/issues/45

These are called generics. PHP currently doesn't support them, but there is work being done towards them being added. There are a lot of complications that need to be figured out before they can be implemented.
