Nytescript

By right this is a fork of https://github.com/davidcallanan/py-myopl-code It is a simple, interpreted esoteric programming language (esolang) implemented in Python. It's designed to be an easy language to use and remember syntax for, similar to the ancient BASIC. Examples of functions include print(), input_char(), run() (Runs Nytescript Files) and so on.

Warning:

Nytescript is not intended for practical use. Its primary purpose is for fun, experimentation, and exploring the boundaries of my skill :)

Getting Started

Prerequisites

• Visual Studio Code (Preferrably): Used because there is an extension at Nytescript on VSC Marketplace
• Code Runner Extension (On VSCode) So you can run your Nytescript Files from the Play Button (Only after running setup.py)
• Python 3.12 or higher: Ensure you have Python installed on your system. You can download it from Python Downloads.

Installation

1. Clone or download the Nytescript repository:

   git clone [https://github.com/nnnGi/nytescript.git](https://www.google.com/search?q=https://github.com/nnnGi/nytescript.git)
   cd nytescript

2. (Optional) Create a virtual environment:

   python -m venv venv
   source venv/bin/activate  # On Linux/MacOS
   venv\Scripts\activate  # On Windows

3. Run shell.py from Python without arguments for the shell, and provide the filename of a Nytescript (.ns) file that you want to run as an argument in the python shell.py example.ns format OR install the CLI from setup files provided and use the CLI universally with nytescript example.ns

Notes: No libraries apart from standard library are used

Further Information

Nytescript Esolang, written by @_nnn_ in Python 3.12.9 and 3.13.2 and 3.13.3

It is based on the interpreter https://github.com/davidcallanan/py-myopl-code by David Callanan

This is an interpreted programming Language made in Python named Nytescript. It has essential functions such as printing, input, conditional statements, definable functions, while and for loops, switch and try-except statements, and the ability to run files and exit the programme.

Nothing needs to be installed except the nytescript.py and shell.py file, preferably Python 3.12 and above.
