## BrainFuck Compiler
BrainFuck compiler in Rust procedural macro metaprogramming.

## Usage
The BrainFuck code from [https://fatiherikli.github.io/brainfuck-visualizer/](https://fatiherikli.github.io/brainfuck-visualizer/), see it how to work.

The BrainFuck compiler generates the below code to "Hello World!" at compiler time(metaprogramming), and printing it at run time.

Implementing in Rust procedural macro way.

```rust
extern crate brain_fuck;
use brain_fuck::brain_fuck;
fn main() {
    println!("{}", brain_fuck!(
        ++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.
        >---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.
    ));
}
```

emit asm code:
```nasm
