MathViz is a modern programming language designed specifically for creating mathematical animations. It extends Python with a clean, math-first syntax and compiles to pure Python with first-class Manim integration.

Features

• Unicode Math Operators — Write math naturally: ∈, ⊆, ∪, ∩, ∞, π, ≤, ≥, ≠
• Clean Syntax — Modern block syntax with let, fn, scene, and pattern matching
• Manim Integration — First-class support for creating mathematical animations
• Static Analysis — Built-in check, analyze, typecheck, lint, and fmt commands
• Module System — Multi-file projects with use imports
• Desktop Editor — Cross-platform editor with live preview (Tauri + React)
• Fast Iteration — REPL mode and file watcher for rapid development

Installation

Using pipx (Recommended)

pipx install git+https://github.com/CyberSnakeH/MathViz.git

Using uv

git clone https://github.com/CyberSnakeH/MathViz.git
cd MathViz
uv sync --dev

Using pip

git clone https://github.com/CyberSnakeH/MathViz.git
cd MathViz
pip install -e ".[dev]"

Prerequisites

• Python 3.12 or higher
• Manim (for animations)
• LaTeX (optional, for math rendering)

Quick Start

Hello World

Create a file hello.mviz:

fn main() {
    println("Hello, MathViz!")
}

Run it:

mathviz exec hello.mviz

Your First Animation

Create animation.mviz:

from manim import Circle, Create, FadeOut

scene CircleAnimation {
    fn construct(self) {
        let circle = Circle()
        circle.set_color(BLUE)

        self.play(Create(circle))
        self.wait(1)
        self.play(FadeOut(circle))
    }
}

Run with preview:

mathviz run animation.mviz --preview

Language Features

// Variables with type inference
let x = 42
let name = "MathViz"
let pi = 3.14159

// Functions with type annotations
fn add(a: int, b: int) -> int {
    return a + b
}

// Pattern matching
let result = match x {
    0 -> "zero"
    1 -> "one"
    _ -> "other"
}

// For loops with ranges
for i in 0..10 {
    println(i)
}

// List comprehensions
let squares = [x^2 for x in 1..=10]

// Unicode math
let is_member = 5 ∈ {1, 2, 3, 4, 5}
let union = {1, 2} ∪ {3, 4}

CLI Reference
