The calc_compiler project

Having an analyzed program (and its matching symbol table), it is easy also to create a program that translates it into another language. To avoid introducing a new language, the Rust language has been used here as a target language, but translating to other high-level languages would be no more difficult.

To run it, go into the calc_compiler folder and type cargo run data/sum.calc. After compiling the project, the program will print the following:

Compiled data/sum.calc to data/sum.rs

If you go into the data subfolder, you will find the new sum.rs file, containing the following code:

use std::io::Write;

#[allow(dead_code)]
fn input() -> f64 {
    let mut text = String::new();
    eprint!("? ");
    std::io::stderr().flush().unwrap();
    std::io::stdin()
        .read_line(&mut text)
        .expect("Cannot read line.");
    text.trim().parse::<f64>().unwrap_or(0.)
}

fn main() {
    let mut _a = 0.0;
    let mut _b = 0.0;
    _a...
