Just another Brainfuck interpreter in Ruby! (If you don't know what Brainfuck is, you definitely should).

This interpreter works with MRI 1.8.7, 1.9.2 and JRuby 1.5.5.

UPDATE: Known caveats solved since 0.1.0!

Thanks to a complete rewrite using Kaspar Schiess' parslet (which you should definitely check it out) nested loops work flawlessly. So yes, you can now run that high-security online payment system you wrote in Brainfuck :)

Installation and usage

You just gem install brainfuck (or gem 'brainfuck' in your Gemfile)!

And then: brainfuck

You can also require the gem and use inline brainfuck in your ruby scripts like this:

require 'brainfuck' "+++>+++<---"
# => [0, 3]

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add specs for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. If you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull.
  • Send me a pull request. Bonus points for topic branches.
