BrainFuck Auto Formatter

BFAF - BrainFuck Auto Formatter

Tiny command line utility that gives reasonable formatting for brainfuck files.

-- by Sebastian Mestre --
-- usage: bfaf [-o <name>] <file>
-- default out is <file>.formatted

Converts:

[-]+++++++hello there!+[>+++>++>++++>+++++<<<<-]

To:

[-]
++++ +++
hello there!
+
[
	>
	+++
	>
	++
	>
	++++
	>
	++++ +
	<<<<
	-

Most of what it does is just indentation and separating different operators to different lines, but it does pack a few more tricks that make formatting a bit nicer:

• Idiomatic interpretation of [-] and [+] as a single unit
• Grouping of strings of the same operator into groups of 4, space separated
• Grouping of strings of the same operator into groups of 16, new line separated
• Mantaining of whitespace on strings of non-brainfuck characters

Building

At the moment it's a single .cpp file, so you can compile it directly using your favorite compiler. I like GCC so, in my case, it looks like this:

g++ src/main.cpp -o bin/bfaf
