Supporting hhvm 4 for as long as possible.
Branch
You are currently looking at the hhvm@next (6 and above) branch of this repository.
Why is this needed?
HTL software supports a large range of hhvm versions. Older hhvm versions need some arcane incantations that newer hhvm versions do not support anymore. This library allows me provide two definitions for one function, and load the right one based on your reported hhvm version.
For example, varray(...) is not supported on hhvm@next, but required to be
used in some edge cases on hhvm version 4.102. downgrade_vecish is an
alternate spelling for varray(...) on hhvm 4 and for vec(...) on hhvm 6.
Future of hhvm 4 support
I wanted to add support for hhvm@next to HTL, without removing unofficial support for hhvm version 4.102 through 4.151 in the same release. This library allows me to do that. On September 1st 2025, I will drop unofficial support for hhvm version 4.151 and below. This library will stick around to support hhvm version 4.153 through 4.168 for a while. It is unclear at this time when support for these versions will be dropped.
