Loxscript

Python port of the book crafting interpreters with some of my own changes and additions.

Features and quick tutorial

You could find the tutorial here

Requirements

  • python >= 3.8

Installation

Install with pip

$ pip install git+https://github.com/yashrathi-git/loxscript

Now you could run loxscript to access the interpreter.

If you are doing user install, you must add the user-level bin directory to your PATH environment variable in order to use loxscript. If you are using a Unix derivative (FreeBSD, GNU / Linux, OS X), you can achieve this by using export PATH="$HOME/.local/bin:$PATH" command.

Usage:

$ loxscript # Starts a loxscript repl
$ loxscript path/to/source_code.ls # Executes the file

Without pip

  1. Clone the repo 
    $ git clone https://github.com/yashrathi-git/loxscript
  2. Navigate to source code directory. 
    $ cd loxscript
  3. Running(Make sure you are in the source code directory): 
    $ python run.py # Starts a loxscript repl
$ python run.py path/to/source_code.ls # Executes the file

TODO:

  • ADD TESTS!
  • Support for multiline comments
  • Complete classes and inheritance part
  • Lists and Dicts
  • Lambdas
  • Provide builtins to do web-requests
  • Add setup.py for direct install
  • Add support for decorators
  • Add more builtins with decorators like @property, @classmethod etc.
