As far as I know Hack had h2tp utility to complile Hack code to PHP.
But today I couldn't find this command in any of official prebuilt HHVM packages for Ubuntu, and Facebook's blog post link redirects to getting started page. And judging by this comment h2tp is dead.
But is it still possible to compile from sources/download outdated version of HHVM to somehow use h2tp?
And if yes, how do I do it correctly?
Yes, it is possible via docker on Ubuntu 18.04.
