Turing Tarpit, A Brainfuck Interpreter
This was built as a demo application for Practicing Ruby Issue 3.3. You can subscribe to the journal at: http://practicingruby.com
Using Turing Tarpit
You need Ruby 1.9.3 to make this project work. It might be possible to get the code running using 1.9.2 + the io-console gem, but that's completely untested currently.
Turing Tarpit can be installed as a gem via rubygems.org, but if you're thinking about hacking on it, the easiest way to try it out is to run the "Hello World" program included in this repository:
$ ruby bin/turing_tarpit test/fixtures/hello.bf
There is also a Rot13 example (test/fixtures/rot13.bf), but be warned: You need to know how to enter null characters to be able to cleanly exit it. In OS X terminal, this can be done by pressing Ctrl+Shift+2.
Both examples are based on the code in the Brainfuck Wikipedia article.
