RustFuck - Oh Fuck, its Rust

Intro

Wrote a cool little brainfuck interpreter in rust. Mostly to test how cool rust is, since I have been hearing so much about it lately. Also to test if neovim behaves well with rust (PS: It really does!)

Usage

1. Run cargo build --release to build the interpreter, rust should automatically install all deps.
2. Run the binary like so ./brainFuck --input ./inputFile.b

This interpreter implements the 'canonical' reference.

Some changes/choices

• '&' inserts an EOF character while taking in input. (EOF sets memory cell to 0 if entered while input(,) is required)
• EOF: enters a 0 in the memory location.
• '#' command prints state (Data pointer location, Instruction pointer location, Memory state)
• Each memory cell is 8 bit wide, underflow(during -) and overflow(during +) wrap around. Incorrect memory access panics.
• Memory is 30,000 cells long.
• Loop bracket matching is done during parsing.

Examples

examples has some really cool examples, most of them are taken from 'brainfuck.org' or wikipedia. Try GOL.b and numwarp.b
