Brainfuck interpreter

This is a simple brainfuck interpreter written in rust.

Tests in the test folder come from the brainfuck.org website.

Compilation

Simply run cargo build --release to build the interpreter, you will then find the executable in the target/release folder. Alternatively, run cargo run -- [OPTIONS] to run the executable directly.

Example runs

Simple execution

$ ./brainfuck -f examples/hello_world.b
