So you've got a cool app in Ruby, and you want to share it with your friends, but they don't love Ruby as much as you.

What do you do? Package it up along with the Ruby runtime and give it to them. Simple right? Maybe not so.

Thankfully smarter cookies than me, have tackled the problem, here is a map of the current state of play

CDCT Python

Pact-Python currently uses the Ruby core, and for the verification task, utilises the following repository

There are a few modes of verification

	// simplevm.c: demonstrates Hypervisor.Framework usage in Apple Silicon
	// Based on the work by @zhuowei
	// @imbushuo - Nov 2020

	// To build:
	// Prepare the entitlement with BOTH com.apple.security.hypervisor and com.apple.vm.networking WHEN SIP IS OFF
	// Prepare the entitlement com.apple.security.hypervisor and NO com.apple.vm.networking WHEN SIP IS ON
	// ^ Per @never_released, tested on 11.0.1, idk why
	// clang -o simplevm -O2 -framework Hypervisor -mmacosx-version-min=11.0 simplevm.c
	// codesign --entitlements simplevm.entitlements --force -s - simplevm
