asciimath-rs

Parses mathematical (infix) expressions into an Abstract Syntax Tree using Dijkstra's "shunting yard" algorithm.

Simple, bare-bones, and efficient.

Features

• evaluation
• support for variables
  • with artibrary number of characters (e.g. abcde)

Goals

• [ ] functions
  • [ ] basic (sin, cos, etc)
  • [ ] user-defined
• [ ] matrices (maybe)
• [x] documentation

Non-goals

• non-mathematical expressions
• php-esque abominations like a=func(x) && b=func(y) && 'what'

How-To

```rust extern crate asciimath; use asciimath::Evaluate;

fn main() { let expression = "x + 4 * 2 / ( 1 - 5 ) ^ (2 - 2 ^ 3)";

let mut scope = asciimath::Scope::new();
scope.set_var("x", 3);

println!(
    "{:?}",
    asciimath::parse(expression).eval_with(&scope)
);

} ```
