The warnings about MacOS are mostly being cautious, as I don't think anyone actually runs it in production. I work with open source Hack code a lot, and I almost always use the Mac…

To clarify, xhp-js was not server-side rendering - it's a framework for generating javascript code, and getting an DOM element ID for a react element that the hack code can refer t…

> Are there any large Hack codebases I can explore? depends what you mean by 'large' - perhaps https://github.com/hhvm/user-documentation ? > Does anyone know if FB tracks changes …

Facebook doesn't. Open source users of Hack do, and it uses packagist.org - however if a package is written in PHP, Hack code can't use it. Not 100% accurate, but if a package's co…

There's also https://github.com/hhvm/hack-codegen/tree/master/examples/do... , along with the article at https://engineering.fb.com/2015/08/20/open-source/writing-co... This is mod…

> Now I also don't know if I buy that MAX_INT + 1 and pass-by-reference is a pressing enough use case to break compatibility. I'd be open to hearing why, but I'd be starting from a…

https://github.com/hhvm/hack-router/ and https://github.com/hhvm/hack-router-codegen/ power docs.hhvm.com and some of our other users; they do have problems such as extremely lacki…

For completeness: Sara Golemon started porting Facebook's old PHP5 implementation of XHP to PHP7 - you can find it here: https://github.com/phplang/xhp + https://github.com/phplang…

we're currently leaning towards out/inout parameters, with copy semantics, not byref (and in most cases, we'll probably be able to optimize away the copy); not certain yet though.

You'll also see a few of these on http://php.net/manual/en/migration70.incompatible.php :p

Sorry, I know this is a pain; I'm hoping to fix it by the end of the year (along with bringing back nightly debs, and supporting more recent versions of debian/ubuntu). For homebre…

> my ask is to just make a better language and drop ALL of PHP baggage. Long-term, we hope to make pure-hack projects more practical, and we're aiming to make Hack the best web dev…

I'll leave the first part of your question for someone less close to the project. For the toolchain, when using it: it's currently mostly the PHP toolchain (e.g. composer) with som…

Function naming: We're moving towards functions_like_this(), instanceAndStaticMethodsLikeThis(), and async functions like foo_async() and methods like fooAsync(). We're unlikely to…

Thanks; we don't feel that the framework authors have to make a choice here: - short-term, those of us working on HHVM - not the frameworks - need to make sure that HHVM can run th…

There's https://github.com/facebook/squangle for MySQL, though it's lacking documentation, and requires a https://github.com/facebook/mysql-5.6 or WebScaleSQL client library

No - it still renders the element client-side so that it supports interactive components. See: https://github.com/hhvm/xhp-js/blob/master/src/XHPReact.php https://github.com/hhvm/x…

RE exceptions: in HHVM at least you can change this: 1. set hhvm.error_handling.call_user_handler_on_fatals=true in your ini file 2. throw exceptions from your handler :)

People are having lots of success with https://github.com/mongofill/mongofill-hhvm

also, if this is an open source workload, any chance you could submit it to https://github.com/hhvm/oss-performance ? We generally optimize based on those benchmarks, and Facebook …

do you have any profiling information to share? if you could post it as a github issue, we'd be very interested. This sounds unusual.

Here's one :) https://github.com/facebook/vim-flow/
