Lox

Various implementations of Robert Nystrom's Lox language from Crafting Interpreters.

Implementations

In the project subdirectories, there are implementations of the Lox language in a few different languages.

Tree-Walk Interpreters:

• Java : jlox
• Python : plox
• Kotlin : klox

Bytecode Virtual Machines:

• C : clox

Running

From the top-level directory, run

./gradlew build

This will build the jlox and klox projects and run all tests.

Language Extensions

My implementation of the Lox language adds the following additional features:

1. +=, -= operators for addition-assignment, subtraction-assignment
2. Additional built-in functions, exit(exitCode), print(msg), printErr(msg)
3. Support for integer literals. Number literals without a '.' will be parsed as integer types.
4. Built-in property for an object's class, e.g., print Foo().klass
