loxide

An implementation of Lox from Crafting Interpreters.

Current Progress

Finished Chapter 7.

Currently the compiler will tokenise the source, and then parse a single top-level expression. If it encounters an error it will print it to the screen. It then uses a tree-walk interpreter to evaluate the expression, and prints the result to the screen.
