asciimath-rs

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

Simple, bare-bones, and efficient.

Features

support for variables
evaluation
- compile the expression just once, evaluate with a different set of variables
implicit multiplication

Roadmap

Error handling and propogation
Embedded constants like pi and e
Functions
- basic (sin, cos, etc)
- user-defined
Support for word-variables (right now only single-letter variables are supported)
Thorough documentation
- basic use
- available functions

Future Goals

The items below will be considered after ABI stabilization:

Non-mathematical expressions, like strings
More operators (e.g. ternary ? : )
Ability to simplify expressions
Derivatives, incl. second-order and third-order
Integration
Partial differentiation
Vector calculus
Matrices and vector spaces

Non-goals

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