jlox

Java Lox implementation, following the excellent and beautifully crafted book Crafting Interpreters by Robert Nystrom.

Usage

Generate the AST and compile first:

javac com/craftinginterpreters/tool/GenerateAst.java
java com/craftinginterpreters/tool/GenerateAst com/craftinginterpreters/lox
javac com/craftinginterpreters/lox/*.java

Then, to use the interactive interpreter:

java com.craftinginterpreters.lox.Lox

(The interactive interpreter doesn't allow code blocks over multiple lines.)

To run script files:

java com.craftinginterpreters.lox.Lox tests/hello-world.lox

Gotcha's

I never took out the AST printer functionality from one of the early chapters. This required me as a result to add a printer method each time I added to the AST in subsequent chapters. For that I simply looked up the reference implementation at https://github.com/munificent/craftinginterpreters/.
