recalc

I've made this project to learn a little bit about the Rust programming language. It is a reactive calculator, meaning that expressions are always lazily evaluated. Take a look at the following example:

> x = 10
x = 10
> y = 2 * x
y = 20
> x = 20
x = 20
> y
40

Getting Started

Clone this repo and run cargo run. You will be greeted with a REPL where you can input commands. You can use

• +, -, *, /, and ^ to perform calculations;
• pi and e constants;
• sin, cos, and tan functions;
• = to define variables.

Disclaimer

This is a toy project, there are bugs and they can bite you. For instance, don't try this: x = x.

Future

I would like to advance this project to include the following features:

• Pin board, an area showing pinned variables
• Array formulas
