A Rust library that reads logical propositions and interprets them to build truth tables and ASTs.
Logic Tracer is a Rust library designed to parse and interpret logical propositions, automatically generating truth tables and Abstract Syntax Trees (ASTs) from input expressions. Makes use of regular expressions to validate the input and tokenize the proposition.
🚦 Getting Started
Examples
Check the examples directory to see how to use the crate.
Features
Current
- Read a logical proposition
- Tokenize the proposition
- Validate Input Tokens (only valid tokens)
- Variables (only letters)
- Logical Operators (and, or, not, implies, iff)
- Mathematical Operators (add, sub, mul, div, pow)
- Compounds (only numbers, variables, variable with subindex)
Planned
- Parse the proposition (make sure it is valid)
- Build the AST (Shunting Yard Algorithm) (use postfix notation)
- Add notation to the AST (prefix, infix, postfix)
- Solve proposition (evaluate the AST)
- Add good looking output for truth table, ast, function, etc.
- Reduce a proposition to its simplest form (boolean algebra)
- Reagrupate Compounds (boolean algebra)
- Apply De Morgan's laws (boolean algebra)
- Apply distributive, associative and commutative laws (boolean algebra)
- Add more examples
- Add more tests
- Improve documentation
- Improve the import/export of the crate (to improve it's usability as a library)
I want to make this crate completely independent of any other crate.So, I will implement the parser myself...
