Version 0.2.1 is Live on PyPI

The AI-Ready Language
Built for Simplicity & Speed

Name: Cruise Programming Language
Author: Manjas Anand

Cruise is a lightweight programming language created by Manjas Anand featuring human-readable syntax, custom user-defined functions, PyTorch tensor calculus, and HTTP request libraries.

Support My Work

Why Developers Love Cruise

Engineered from the ground up to combine plain-English readability with powerful deep learning backend tools.

User Defined Functions

Declare modular functions easily using plain-English syntax: define name(arg): ... end with dynamic scoping.

PyTorch Autograd

Native support for multi-dimensional tensor arrays (tensor([1, 2, 3])) with built-in matrix calculations.

Native HTTP Library

Fetch JSON data and communicate with external REST APIs directly inside scripts using fetch(url) and post(url).

Zero-Config GUI Apps

Build instant desktop windows (background, button) with graceful headless fallback handling for terminal environments.

Dual File Extensions

Run interactively line-by-line via the REPL shell, or execute standalone script files saved with .cru or .crui extensions.

Cross-Platform REPL

Lightweight terminal shell designed to execute scripts on any machine with Python 3.8+.

📖 Complete Documentation & Syntax

Master all keyword functions, operators, and standard capabilities built into Cruise.

Feature Category	Cruise Syntax Command	Description & Behavior
Functions	define greet(user): ... end	Defines reusable custom function blocks with parameters.
Variables	x = 100	Assigns numbers, strings, or tensors to variable scopes.
Print Output	write("Hello " + name)	Prints variables, expressions, or strings to console output.
Automation Loops	3 times write("Hi")	Repeats a command N times in a single line.
HTTP API GET	data = fetch("https://api.com")	Sends HTTP GET requests to fetch remote JSON data.
Tensors (PyTorch)	t = tensor([1.0, 2.0, 3.0])	Creates multi-dimensional tensor arrays for ML math.
Desktop UI Window	background("navy")	Initializes desktop app window background with headless fallback.
Interactive Button	button("Click Me")	Mounts clickable UI button component on desktop windows.

PyPI Package (`cruise-lang`)

The core interpreter is published on PyPI. Install it on any device with Python 3.8+ (including iPad terminals like iSH / Pythonista).

pip install --upgrade cruise-lang

PyTorch Tensor Engine

Cruise connects directly to tensor math matrix algorithms to perform linear algebra calculations without writing complex C++ boilerplate.

t = tensor([1, 2, 3])
