# Franca

Macros for writing terser Rust code. This crate contains both a library that exports the macros and a binary that transforms any Rust code to Rust code that uses the exported macros.

Access the online demo hosted on github pages [here](https://x86y.github.io/franca).

## Example code written using Franca macros:

```rs

use franca::*;

pub struct Program {

    pub p: usize,

    pub a: Vec,

    pub ip: usize,

    pub b: Vec,

}

impl Program {

    pub fn eval(&mut self, s: Sstr) {

        lm!(st, vec![]; b, 0; a, &mut self.a; p, &mut self.p; ip, &mut self.ip);

        l!(by, s.as_bytes());

        W!(*ip < by.len(), {

            l!(c, _c!(by[*ip]));

            M!(c; ']', {Ic!(nz!(a[*p]), *ip = st.pop().unwrap()); b = *ip};

                  '[', {Ic!(z!(a[*p]), *ip = b); st.push(*ip)};

                  '+', ic!(a[*p]);

                  '-', dc!(a[*p]);

                  '>', ic!(*p);

                  '<', dc!(*p);

                  '.', self.b.push(a[*p]);

                  ',', {};

                  _, unreachable!()

            );

            ic!(*ip);

        })

    }

}

```
