I wanted to see what Brainfuck is about so I wrote up a PHP BF interpreter. Couple things I think would be good TODO:
- Inject the read/write streams into the Brainfuck class - it's 23:10 now and I want to go to bed (and after seeing the "hello world" program running, interest has flagged).
- Once we have the above working, actually write tests for the input/output commands.
- Maybe write a couple more tests of failure - BF is a pretty forgiving language though ...
- Chage up the dodgy(ish) bracket matching functionality. It works, I suppose, but there's probably a much more elegant way of doing (basically all of) it.
Importantly, though, I think this would be a great pair-programming/code-retreat exercise. Will try expand this to be a TDD task/kata.
Fun project though!
