Introducing fhck, a brainf*ck interpreter written in Haskell!

If you haven't heard of brainf*ck, you should totally check it out, because it's probably the coolest programming language of them all!

Also, probably one of the simplest...

That's why I decided to write an interpreter for it!

This is the product of about 3 days of work, give or take, but the sessions were long and I put a lot into it.

If you're a Haskeller reading this, please feel free to critique it (I'm sure it could be improved in many places)!

If you're not, please feel free to check it out anyway! I encourage everyone to play around with brainfuck a little bit because it's actually a  lot of fun.

If you're not familiar with the language, a quick look through brainfuck's Wikipedia page should help you to understand what's going on in brainfuck (it's not too complex).

With the interpreter, you can write a file, say thisisbf.b, containing the classic "Hello, world!" brainfuck program directly from the wikipedia page:

	+++++ +++++ initialize counter (cell #0) to 10
	[ use loop to set the next four cells to 70/100/30/10
	> +++++ ++ add 7 to cell #1
	> +++++ +++++ add 10 to cell #2
	> +++ add 3 to cell #3
	> + add 1 to cell #4
	<<<< - decrement counter (cell #0)
	]
	> ++ . print 'H'
	> + . print 'e'
	+++++ ++ . print 'l'
	. print 'l'
	+++ . print 'o'
	> ++ . print ' '
	<< +++++ +++++ +++++ . print 'W'
	> . print 'o'
	+++ . print 'r'
	----- - . print 'l'
	----- --- . print 'd'
	> + . print '!'
	> . print '\n'

view raw thisisbrainfuck.b hosted with ❤ by GitHub

and pass it to the interpreter:

on Windows:

$ build\windows\fhck.exe thisisbrainfuck.b

or Linux (or presumably Mac OSX, though I haven't tried):

$ build/linux/fhck thisisbrainfuck.b

...and it should print "Hello, world!" to your console!

Neat, right? (I think so!)
