Presentation

This project was the final project for a Compilation course at university, which you can see here. The goal is to create an interpreter for a java-like language called Kawa, using the extension .kwa.

Requirements

This project was used with the langage Ocaml, you will need to have dune and opaminstalled on your computer, as well as the Ocaml library menhir.

How to use it

Once you have the requirements, write the Kawa code in a code.kwafile, and type dune build. Then type ./kawai.exe code.kwa and your code will get executed.

Addtionnal options

When typing ./kawai.exe code.kwa, you can add options to help you :

• Adding -s will display which step the code is (Lexing the file, parsing, typechecking or interpreting it)/
• Adding -env will display the name and types of every variables allocated at the beginning.
• Adding -cl will display informations about the classes of your file : their attributes, their methods and the signature of these methods.
• By adding -F, the program will not interpret the file, simply parse it, typecheck it. It can be used in pair with -cl to just show the classes for example.

Examples :

• ./kawai.exe code.kwa -s -env will show the steps of the program and the variables allocated.
• ./kawai.exe code.kwa -cl -F > code.txt will stock the classes, methods defined in code.kwa in a file. The code defined in the main function will not be executed.
