Hack

It’s time for a new LTS! 4.168 is out, ending support for 4.128: hhvm.com/blog/2022/09/0…

If anyone is interested in learning a new language, I just pushed an update/overhaul for the Hack language (@HackLang) to the Learn X in Y Minutes site. Hadn't had a major update in >7 years! learnxinyminutes.com/docs/hack/

We have a new LTS, 4.153! We’re also going to be moving to a two-week cycle - read more at hhvm.com/blog/2022/03/1…

We’re skipping 4.132 due to issues with the nightly builds; we expect to be back with 4.133 next week.

Join @lemonit tomorrow talking about exploring Hack applications with @arangodb!

If you’re having trouble with breakpoints in VSCode outside of lambdas, add hhvm.debugger.enable_debugger=1 to your configuration. This is only intended to be necessary for hphpd, but was accidentally used elsewhere. We’re also working on the lambda issues.

We are cancelling the release of 4.125 due to issues with the RC builds; we expect to continue with 4.126 next week.

Initially we've open-sourced indexers and schemas for Javascript (Flow) and Hack/PHP, there also exist indexers for Python, Rust, C++/Objective C, and Java that we hope to open-source in the future. We'd welcome community-contributed indexers for other languages. [6/8]

Glean is designed for high-performance large-scale source code indexing. Store information about your source code and query it efficiently, to power things like IDEs, code browsers, and analysis tools. [2/8]

I'm delighted that we're finally able to open source Glean, the system we're building at Facebook for collecting and querying information about code: glean.software [1/8]

Sorry y’all, we’re delaying this weeks release (we’re expecting Thursday) to fix an assertion failure we’re seeing in many open source projects on our nightly builds

GitHub copilot works with @HackLang and @NuxedFramework 🤯

I just released Tarry, a small @HackLang TAR utility: github.com/azjezz/tarry/t…

We’re on Slack! Come join us at hhvm.com/slack

The Hack Standard Library (HSL) is now built in to HHVM 4.108 and the typechecker, including HSL-IO, which is no longer experimental hhvm.com/blog/2021/05/0…

@SergiiShymko @azjezz @mattbrowndev @OndrejMirtes @psalmphp @phpstan This is often useful to convert a different - but common - error reporting mechanism to exceptions. e.g. a `throw_errno(posix_get_last_error())` helper which might throw a NotFoundException, AlreadyExistsException, IsADirectoryException, IsNotADir… as appropriate

@HackLang @azjezz @mattbrowndev @OndrejMirtes @psalmphp @phpstan Interesting. Thanks for this example. My only concern would be that such "noreturn" functions are rather rare. Most functions will throw exceptions (or exit() which they shouldn't) conditionally. In this case "noreturn" won't apply to them and won't help with the static analysis.

@SergiiShymko @azjezz @mattbrowndev @OndrejMirtes @psalmphp @phpstan if ($x === null) { call_noreturn_func(); } // can assume $x is not null here, but couldn’t if func was void

@azjezz @mattbrowndev @OndrejMirtes @psalmphp @phpstan @HackLang What do you mean by "halt execution"? Exceptions do not halt execution, they just interrupt the sequential execution flow. I don't see a conceptual different between ordinary functions/methods that occasionally throw exceptions and ones that always throw. Why distinguish them?

Just finished 3 great months hacking higher-kinded types into @HackLang. Hope I fixed more than I broke 🤔
