How to install game-porting-toolkit (aka proton for macOS)

You also might wanna just use Whisky which does this automatically

This guide works on macOS 13.4+ using Command Line Tools for XCode 15 Beta!

# Monkey patch to Sprockets::StaticCompiler, a class provided by actionpack
# that's used by the assets:precompile task. This patch uses the Parallel gem
# to parallelize asset compilation in the simplest way possible.
#
# Parallel wraps Process.fork to handle things like inter-process communication
# via pipes and determining the maximum number of processes to run based on
# your system's total logical processors. So far only tested on MRI 1.9.3 on OS X.

1. Capistrano deployment speedup
2. Use @import carefully.
3. don’t require .scss & .coffee for no reason
