Swift Implementation of a Lox Interpreter.
Lox is a dynamically typed and turin complete programmimng language.
Note
This implementation have achieved 100% of Lox's main specification. And couple challenge specification. I have plan to work on a Swift based DSL that builds on top of this project; and a compiled version of Lox with a lower level lanaguge. I consider Slox as done.
This project follows the book Crafting Interpreters written by Bob Nystrom.
Note
This project sometimes deviate from offical implementation in the book (the interpreter not the language). For better conformance with Swift feature and standard paractice. I also made an effort to make this project more extensible, since I intend to use this as foundation for future project.
