cargo-unfmt

Unformat code into perfect rectangles!

Take control of your formatting and turn this convoluted code:

#![feature(coroutines, coroutine_trait)]

use std::ops::Coroutine;
use std::pin::Pin;

fn main() {
    run_coroutine::<i32>();
}

fn run_coroutine<T>() {
    let mut coroutine = || {
        yield;
        return;
    };
    Pin::new(&mut coroutine).resume(());
}

into this beautiful block:

#![feature(coroutines,coroutine_trait)]use std::ops::Coroutine;use std::pin:://;
Pin;fn main(){;run_coroutine::<i32>();;}fn run_coroutine<T>(){let mut coroutine=
||{{;};yield;{;};{;};return;{;};};();();Pin::new(&mut coroutine).resume(());();}

Installation

Install using cargo with:

cargo install cargo-unfmt --locked

How does it work?

Through a combination of lexical and syntactic analysis, cargo-unfmt inserts no-op statements like if false{}, extra parenthesis around expressions, and comments to achieve perfect blocks. It tries to minimize the size of the resulting code as well as minimize the number of end of line comments.
