Explore Ryven: Visualize Python Scripts with Interactive Data and Execution Flows

Typical black‑on‑white code can be boring, so why not visualize Python scripts? With Ryven you can clearly see each step, such as loading an image, resizing it, and applying bilateral filtering.

Entering a matrix—whether transposing, conjugating, or exponentiating—gives immediate feedback.

The visual scripting tool, called Ryven , was created by a freshman named Leon Thomm. To try it, follow the steps below.

How to Use

Prepare the development environment first:

Python 3 (recommended 3.8+)

PySide2 (recommended 2.14+)

Run Ryven.py in the project to open the editor. Ryven contains many scripts, each with variables, a flow (or graph), and a log. Right‑click for easy operations. To use nodes, import the node package by clicking File → Import Nodes and selecting the *.rpc files.

The tool features two algorithm modes:

Data Flow : Every data change propagates forward instantly, updating all connected nodes. Sliding a slider immediately updates results in the right‑hand nodes.

Execution Flow : Data does not propagate on change; updates occur only when a node requests output, triggering updates in affected nodes.

The author also lists a to‑do list, including syntax highlighting, auto‑code completion, and visual improvements.

Visual programming can be fun, but the author emphasizes that it is not meant to replace text‑based programming , as many tasks have no need for a visual approach.
