Renk is an indentation-based syntax for Rust, inspired by Rust’s Ugly Syntax. renk transpiles .rk files to Rust and converts Rust back to Renk.

#[derive(Debug, Clone)]
pub struct User:
    pub id: u64
    pub name: String

impl User:
    pub fn new(id: u64, name: String) -> Self = Self{ id, name }
    pub fn display_name(&self) -> &str = &self.name

pub fn main():
    let user = User.new(1, "Ada".to_string())
    println!("{user.display_name()}")

Generated Rust:

#[derive(Debug, Clone)]
pub struct User {
    pub id: u64,
    pub name: String,
}
impl User {
    pub fn new(id: u64, name: String) -> Self {
        Self{ id, name }
    }
    pub fn display_name(&self) -> &str {
        &self.name
    }
}
pub fn main() {
    let user = User::new(1, "Ada".to_string());
    println!("{}", user.display_name());
}

Renk changes syntax only. Types, borrowing, macros, and crates are Rust’s, and tokens the transpiler does not rewrite pass through as Rust. A Rust { ... } block, a :: path, or a ::<T> turbofish is always accepted.
