CoreFoundation

This is an FFI wrapper around a subset of CoreFoundation. Currently, only UUID is implemented.

Installation

Install the gem and add to the application's Gemfile by executing:

$ bundle add UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install UPDATE_WITH_YOUR_GEM_NAME_IMMEDIATELY_AFTER_RELEASE_TO_RUBYGEMS_ORG

Usage

UUID

allocator = nil

sixteen_bytes = [
  0x00, 0x11, 0x22, 0x33,
  0x44, 0x55, 0x66, 0x77,
  0x88, 0x99, 0xAA, 0xBB,
  0xCC, 0xDD, 0xEE, 0xFF
]

uuid_ref = CoreFoundation::CFUUIDCreateWithBytes(allocator, *sixteen_bytes)

cf_uuid_bytes = CoreFoundation::CFUUIDGetUUIDBytes(uuid_ref)

cf_uuid_bytes[:byte15] # => 0xFF

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
