Ryven | Flow-based visual scripting for Python | Code Inspection library

and now you can launch it by running ryven on your terminal, and ryven_console for RyvenConsole. If you want to start Ryven from a Python script, just import it and run it like this.
A super quick intro to Ryven. Open Ryven by typing ryven in your terminal (or running Ryven.py with python), and create a new project. Import some example nodes via File -> Import Example Nodes and select std/nodes.py. You should now see a long list of nodes on the left. Drag and drop them into the scene and get a feeling for how they work, everything is being executed at realtime. For instance, drag two val nodes into the scene, wire them together with a + node and display the result in a result node. Now replace one of them with a slider node generating real numbers. You can also get an interactive nodes list preview inside the scene by right-clicking. You can pan around also with the right mouse button, and zoom via ctrl + scroll. You can also create new scripts, rename and delete them. Now let's check out the small example projects: open a new Ryven window and load one of them. Take a closer look and understand what they do. At this point you are ready to start building your own nodes.
