The Lox interpreter in Odin.

The repo for the "Crafting Interpreters" book can be found here: https://github.com/munificent/craftinginterpreters

Disclaimer: I started on this knowing absolutely nothing about Odin and am using this project as a way to get to know the language. The implementation therefor is definitely not idiomatic Odin, and probably very inefficient and "ugly".

If you're an Odin expert, feel free to point out what could be done better!

Make sure you have llvm and clang installed. I had to do the following to get it to work properly:

$ sudo apt install llvm-11 clang-11
$ sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-11 100
$ sudo update-alternatives --install /usr/bin/llvm-config llvm-config /usr/bin/llvm-config-11 100

Install Odin from source:

$ git clone https://github.com/odin-lang/Odin
$ cd Odin
$ make

Make sure to add the Odin folder to your path (or symlink the Odin executable from a location in your path).

$ ./build.sh 
$ bin/olox examples/fix.lox

Look at subtype polymorphism and vtables
