Jack Compiler

This is a compiler front-end for the Jack programming language. The Jack programming language is a simple object-based language, specified in the amazing book The Elements of Computing Systems.

Here is a Hello World program in Jack:

class Main {
   function void main() {
      do Output.printString("Hello world!");
      do Output.println();
      return;
   }
}

The compiler front-end compiles Jack code into VM code that is then executed on a virtual machine.

Usage

Compile the Jack compiler:

cargo build --release

Compile a Jack file:

jack_compiler <INPUT_FILE>.jack

Compile a directory of Jack files:

jack_compiler <INPUT_DIR>

Documentation

To read the documentation, open the file doc/jack_compiler/index.html in a browser.

Tests

The tests compare the outputs of each component (parser, tokenizer, VM writer) to the outputs of the reference implementation.

Running all tests:

cargo test
