Parts of HHVM are implemented in Hack, and are embedded in the HHVM binary as additional ELF PROGDATA sections. This library extracts them from the binary.
There are two kinds of sections that this library extracts:
systemlib: Pure Hack codeext: built-in extensions. These are a mix of normal Hack code, and
functions annotated with the <<__Native>> user attribute, which are
implemented in the C++ runtimeSections with different names or aren't PROGDATA can not be examined with this library.
This package requires the readelf binary; on Debian-like systems, this is in
the elfutils package.
Assuming your project uses Composer:
composer require hhvm/systemlib-extractor
d> require('vendor/autoload.php')
ire('vendor/autoload.php')
d> $extractor = new HHVM\SystemlibExtractor\SystemlibExtractor()
ractor = new HHVM\SystemlibExtractor\SystemlibExtractor()
d> =$extractor->getSectionNames()
tractor->getSectionNames()
