Mathematical Expression Parser

This is a Rust library used for parsing and evaluating mathematical expressions (want to add algebraic manipulations). It is inspired by Sympy from Python and I want to try to make this into a fully working project.

Features

• Parse mathematical expressions from strings
• Evaluate expressions with variable substitution
• Build expression trees
• Compile-time expression parsing with proc-macros
• Support for
  • Basic arithmetic: +, -, *, /, ^
  • Trigonometric Functions: sin, cos, tan, arcsin, arccos, arctan

Crate Structure

The project is organized into three crates:

• expression_core: Contains the Expression type and parsing logic
• expression_macro: Contains the proc-macro for compile-time expression parsing
• expression_parser: High-level API for parsing and evaluating expressions

Installation

Add the following to your Cargo.toml:

[dependencies]
expression_parser = "0.1.0"

For compile-time expression parsing:

[dependencies]
expression_macro = "0.1.0"
