jlox

This is my Java 17 implementation of Lox - a small programming language for scripting - from the book Crafting Interpreters.

One big difference between the reference implementation of jlox and this one is, whereas the reference implementation generates the Expr and Stmt classes by concatenating strings together, this implementation uses JavaPoet, a Java library for generating Java source files in a more type-safe way.

Prerequisites

1. Install a distribution of Java 17. One way to do this is:
   1. Install asdf-vm.
   2. Run asdf plugin add java.
   3. Now, when you "cd" into this directory and run asdf install, running java will use the asdf-managed version specified in .tool-versions.
2. Setup your favourite IDE or text editor to use this distribution of Java 17.

Build the executable

./gradlew build

Run the executable as a REPL

java -jar lox/build/libs/lox-0.1.0-SNAPSHOT.jar

Alternatively, run the Java file com.craftinginterpreters.lox.Lox in your IDE of choice.

Run the executable with a Lox script

java -jar lox/build/libs/lox-0.1.0-SNAPSHOT.jar <path-to-lox-program>
