A simple procedural macro that turns a Brainfuck program into native code.
Example:
```rust
use std::io;
fn main() { let hello_world = brainfuck!{ ++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.> ---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++. };
hello_world(&mut io::stdin(), &mut io::stdout()).unwrap();
} ```
See tests/ and examples/ for some basic examples and the
bf_bf_interpreter subpackage for
brainfuck interpreter written in brainfuck.
This is Cargo enabled, and so can be used
by adding a [dependencies.brainfuck_macros] section pointing to this
git repository to your Cargo.toml. If you wish to also use
bf_bf_interpreter, simply add [dependencies.bf_bf_interpreter]
section also pointing to this repository.
Normal brainfuck, with:
- a tape length of 30000,
- cells storing unsigned bytes (with wrapping),
- EOF indicated by returning -1, and
- out-of-bounds index steps ignored (i.e. < when pointing at the
first cell is just ignored, and similarly for > at the last).
