HHVM Blog:
Hack Recent Updates
October 22, 2014 @ 09:37:26

On the HHVM blog today they've posted some updates about the language that helps power the HHVM (HipHop Virtual Machine), Hack, and the most recent changes and improvements made to the language.

One thing we haven't talked about much is the progress and evolution of the language itself. We've been busy driving the language forward, improving its PHP base as well as adding new features requested inside and outside Facebook to further increase developers' productivity. But unless you're the sort of person that reads every commit going into the HHVM github repository or every change to our docs site, you probably have no idea about any of these changes since we haven't talked much about them yet.

This post is a "kickoff" of a series of posts they'll be doing covering some of the major changes to the language including:

  • Typechecking new static()
  • First-class enums
  • Better understanding the type signatures of the PHP standard library
  • Covariance

Stay tuned to the blog for the full series.

Allan MacGregor:
Exploring Hack Building a MicroFramework
August 11, 2014 @ 09:09:13

Allan MacGregor has started a new series of posts to his site where he creates a microframework in Hack, the language created by Facebook to compliment their HHVM (Hip-Hip Virtual Machine) project. He sees it as a "learn by doing" kind of thing and wanted to share his results.

I honestly believe the best way to learn something is to get your hands dirty and make mistakes; so instead of writing dozens of post on the many new features of Hack and why they are awesome (in theory) let's build something useful. So to get started I've decided to build a micro-framework using HACK and HHVM, building a simple microframework should be a challenging enough task to illustrate some of the more interesting features of the language and at the same time it has an achievable goal so we don't end on a never ending development cycle.

His framework, one he calls "Slash", will mostly be about creating RESTful applications but it could, in theory, be for any kind of web application. He also mentions some of the other great microframeworks out there already that are well-developed and have good communities behind them (including Slim and Silex. This is just the first part of the series and introduces some of the "why" around his goal. In the next part of the series he'll get into the structure and routing with some actual framework code.

Hack How to open the black box of Hacklang as a PHP developer
June 25, 2014 @ 11:56:44

In this recent post to Reddit, user JordanLeDoux shares some of the basics behind the Hack language (from Facebook) and making a "first jump" into it and its strong typing handling.

codebase. Having built HHVM, they wanted something that would enforce certain behaviors for developers that didn't rely on IDE's interpreting phpDoc statements. Hack's most interesting and largest function is that it adds optional strong typing to PHP, by examining the tokenized code and ensuring that where declared strong typing is respected.

Example code is included showing the different levels of typing and how to use them in a few example functions. He introduces some of the basic types included in Hack (like int, float and bool) and some of the types unique to Hack (like mixed, tuples, resource and closures). There's a brief look at maps, vectors and sets and a link to more documentation if your interest has been piqued to learn more and make that "first jump".

HHVM Blog:
Hack Community Roundup
May 19, 2014 @ 12:45:12

For those interested in what's going on in the world of Hack (the Facebook-created language based on PHP) check out this "community roundup" with information about and links to some of the latest happenings.

In the weeks since the Hack open source launch and the Hack developer day, there has been a lot of information, code, blog posts, etc coming from our nascent community. To us on the team, it's been incredible and encouraging to see the community reception to Hack. Here are some of the highlights of the things we've seen come out of our community. (And we almost certainly haven't seen everything, so please let us know in the comments what we've missed!

They share several related GitHub projects (including the Hack/HHVM support on Heroku), a few presentations about installation and experience with the tools and a few blog posts wrapping up their Hack dev day and an article from FastCompany about Hack and its motivation

Lately in PHP Podcast #46 - "Is the Hack Language Going to Replace PHP?"
April 21, 2014 @ 09:12:14

In the latest episode (#46) of the "Lately in PHP" podcast series Manuel Lemos and Arturs Sosins wonder if Hack will ever replace PHP.

The release of the Facebook Hack language has shaken the PHP community since it implements several frequently requested features that were never implemented, many users are considering to drop PHP in favor of Hack. This was one of the main topics discussed by Manuel Lemos and Arturs Sosins on the episode 46 of the Lately in PHP podcast. They also talked about the OpenSSL Heartbleed security bug may affect PHP sites or not, ideas for the PHP 6 engine, the need for an official PHP specification, and an advanced email validation that can provide suggestions for address typos like Google did you mean feature.

You can catch this latest episode either through the in-page audio player, by downloading the mp3 or by watching the video of the live Google Hangout recording.

HHVM Blog:
Hack Developer Day 2014 Keep Hacking
April 11, 2014 @ 09:40:00

On the Facebook HHVM blog today there's a post about the Hack Developer Day they recently held in Menlo Park. The event brought in developers for a day of presentations from the Hack/HHVM engineers.

150+ Members of the PHP and developer community came to Facebook headquarters and joined over 2000 people online for presentations by the engineers of Hack and HHVM. Afterwards we held a five hour hackathon, where the attendees worked with those engineers to write Hack code, either by converting current codebases or writing new code from scratch.

For those that weren't able to attend or are interested in catching up on what was presented, they've posted videos of all of the sessions in a YouTube playlist as well as PDFs of all the slides. If you want the short version of what was presented, there's a quick list in the post or you can read a recap on the Facebook Engineering blog.

Pádraic Brady:
Is Facebook's HHVM Building PHP's Coffin?
April 01, 2014 @ 09:31:52

In a new post to his site, Pádraic Brady poses a question about the HHVM project from Facebook - is it going to "be the coffin" that will replace the Zend Engine in PHP completely and change the way we know it?

With HHVM 3.0 now released, it's probably time to start talking about HHVM and the new Hack Language. It's becoming hard to ignore some of the fantastical notions spreading on the grapevine about HHVM. There is talk of significant performance improvements, a multitude of new features courtesy of Hack, that PHP Internals is actually now outnumbered by HHVM contributors. There is even treasonous talk of PHP's Zend Engine being put out to pasture.

He talks about how it was inevitable, really, that there'd be another implementation come up through the ranks (much like the variations of Ruby). He also mentions some other, less popular options in replacing the main implementation (Zephir, HippyVM, etc). He then poses an interesting question - "what is PHP?" He talks about language specifications, the PHP internals group and the delay that sometimes happens introducing new language features into the core (some of which HHVM already has).

PHP, as we know it, is starting to smell. It has gone from being the only PHP in town, to being the slowest, with the least number of features, and the one that's subject to dysfunctional governance. The new PHP is called Hack, a new language with only the briefest of documentation since you can learn the other 99.9% of this language over on the PHP manual.

HHVM Blog:
HHVM 3.0.0
March 31, 2014 @ 10:15:00

The HHVM blog has an exciting new post for those using the HHVM and Hack language - they've officially released version 3.0.0 with complete Hack support.

At our last major version bump (2.0.0), we basically became a whole new project. We switched from a "PHP -> C++" translator to a virtual machine. This version bump (3.0.0) is a much less dramatic code shift (we're still a VM, don't worry), but this time the big announcement is that we support a new language, Hack.

They take a step back in time and look at the changes since 2.0.0 in organization, technology and community involvement. From there, they get into "the business" of what's in this new release including:

  • The old webserver is gone. If you get something like Uncaught exception: no factory for server type "libevent", you need to switch to fastcgi.
  • We are moving from .hdf config files to .ini.
  • Our most requested extension, mysqli is now in. (there's currently a bug, but the fix will be in 3.0.1).

You can find out more about the HHVM on the project's main website.

Facebook's Hack language a silver bullet for user-developers
March 26, 2014 @ 10:41:16

In this new post to CiteWorld.com, they're making the claim that the Hack language from the developers at Facebook is the "silver bullet for user-developers".

How do you modernize the way we build the web? That's the question at the heart of the release of a flurry of new languages and development platforms -- all from companies that run and build large scale web services. [...] While getting more out of CSS is good, as is replacing JavaScript; Facebook's HHVM and Hack combo is targeting one of the foundations of the modern web: rapid application development.

They talk some about the overall goals of Hack (improved performance, a stricter typing system) and include a brief example of some Hack code. They consider it to be a "more modern language" that brings PHP-based development up into a different level of languages. He also talks about HHVM a bit, migration from PHP to Hack and the potential for Hack to be adopted on other platforms outside of the current HHVM runtimes.
