Symba

Pet project to get acquainted with Rust, and to mess around with symbolic expressions, hence the name 'Symba'.

Example:

    use asg::{deftree, reduce::reduce};

    fn main() {
        let tree = deftree!(/ (+ (* k x) (* k y)) (+ x y));
        let max_iter = 10;
        println!("${}$\n", tree.to_latex());
        let steps = reduce(tree, max_iter).unwrap();
        for step in steps {
            println!("$= {}$\n", step.to_latex());
        }
    }

The above program will produce the following latex output (hopefully rendered by GitHub):

$\dfrac{{{k}.{x}} + {{k}.{y}}}{{x} + {y}}$

$= \dfrac{{k}.{\left({x} + {y}\right)}}{{x} + {y}}$

$= {k}.{\dfrac{{x} + {y}}{{x} + {y}}}$

$= k$

  • Consider making this a commandline tool

    Consider making this a commandline tool

    Many users are not going to recompile symba each time they want to work with a math expression.

    Consider publising a commandline tool that:

    1. Takes the commandline argument and processes it
    2. If no commandline argument, prompt the user, read stdin, process the expression, output the result and return to the prompt
    3. Read from stdin, process and emit results to stdout.
    4. Develop a GUI around symba, making it more accessable and more likely to appeal to Windows and macOS users as well as Linux folk.
