Application wrapper to deploy Ruby apps on macOS using MRI/C Ruby, not MacRuby or JRuby. So far, it has only been used to release Ruby/Gosu games. It can probably be adapted to wrap applications or games written in other toolkits.
The idea is that Ruby.app contains a full, universal Ruby installation.
All you have to do is provide a main.rb file inside the Ruby.app/Contents/Resources/ folder that starts your game/application.
The short answer is that this project is much older than RubyMotion. It is also free, and behaves the same as ‘MRI’ Ruby on the command-line.
The first version of Ruby.app simply ran the user-supplied main.rb file using system Ruby (/usr/bin/ruby).
This is also what Platypus does. However,
- The Ruby that ships with macOS has been deprecated by Apple, and might disappear at any moment.
- Power users frequently mess around with system Ruby, at the very least they might install or remove libraries.
- Ruby/Gosu games tend to use some C extensions, and shipping these is extra painful.
- Optional: Update the Rakefile with the desired Ruby version and gems.
- Install rvm on one Intel Mac, and an ARM Mac.
- Run
rakeon an Intel Mac. This will install Ruby and all required gems via rvm, and then copy them into theUniversalRubyfolder. - AirDrop the folder to your ARM Mac.
- Run
rakeon the ARM Mac. This will build and merge ARM binaries into the UniversalRuby folder. - Optional: If you have updated Ruby, be sure to manually update
rbconfig.rbfrom your rvm-built Ruby (at least the version number should match). - You should now have a self-contained Ruby installation!
The extensions for OpenSSL and YAML will have unportable dependencies on /opt/homebrew ([https://github.com/gosu/ruby-app/issues/8](see issue #8 on GitHub)).
