rubberize 0.4.2

Turn Python calculations into well-formatted, math-rich documents.

Rubberize

Rubberize converts raw Python code into readable mathematical notation so calculations can be clearly presented, reviewed, and documented.

Who is Rubberize For?

Rubberize is designed for:

• Scientists and Engineers: Simplify the presentation of complex calculations in Jupyter notebooks by rendering them as clear, typeset math.
• Educators and Students: Create visually appealing and easy-to-understand mathematical explanations directly from Python code.
• Technical Writers: Generate LaTeX representations of Python calculations for seamless integration into professional-grade documents.

If you work with Python code that involves mathematical computations and want to bridge the gap between raw code and polished documentation, Rubberize is for you!

Installation

Install Rubberize with pip:

pip install rubberize

To include dependencies that allow Rubberize to be used with Jupyter Notebooks:

pip install "rubberize[jupyter]"

Quick Start

[!WARNING] Use of eval(): This project uses Python's built-in eval() to evaluate some expressions. Since it executes code already present in the input source (e.g., a Jupyter cell or script), it poses no additional risk in such environments. However, be cautious when handling untrusted inputs outside controlled settings.

In a Jupyter notebook, load the extension:

%load_ext rubberize

Use the %%tap magic:

%%tap
import math
a = 3
b = 4
c = math.sqrt(a**2 + b**2)

  $\displaystyle a = 3$

  $\displaystyle b = 4$

  $\displaystyle c = \sqrt{a^{2} + b^{2}} = \sqrt{3^{2} + 4^{2}} = 5.00$

Documentation

Full tutorials, configuration options, and examples are found in Rubberize Documentation.

Why The Names?

Rubberize is inspired by tapping rubber trees for latex.

The %%tap command taps a code cell and extracts LaTeX, turning ordinary Python calculations into structured mathematical output.
