Jam entire gem into a binary that works with any ruby.

• 5KB for hello-world executables
• Release a ruby tool as standalone executable (great for github releases)
• Still readable, users can add debugging
• Avoid installing a gem for each ruby version

# https://rubinjam.herokuapp.com/pack/GEM/VERSION
curl -sSfL https://rubinjam.onrender.com/pack/rake > rake && chmod +x rake
./rake --version

gem install rubinjam
rubinjam # convert current directory into a binary

Generate a github token and store it in your ~/.gitconfig with: git config --global github.token <GITHUB-TOKEN>

# Rakefile
require 'bundler/gem_tasks'
require 'rubinjam/tasks'

task release: 'rubinjam:upload_binary'

The server runs via cd server && bundle exec rackup

• ignore json gem if it has no version requirement since 1.9+ includes json
• ruby version requirements
• native extensions
