Is there a step-by-step tutorial which uses a standard file layout?

I can't find "Ryven-master/Ryven/packages/std" on my Ubunty which is what the video shows.

PR to port this to Ryven 3.1 which is not released yet, so do not merge yet. Ryven 3.1 will be a major upgrade for this project too, see also my comment here.

As noted in the discussion, when this is loaded on a Windows machine:

Traceback (most recent call last): File "C:\Users\willa\miniconda3\envs\pyoccenv\lib\site-packages\ryven\gui\startup_dialog\StartupDialog.py", line 99, in load_example_project_button_clicked self.open_project(base_dir=abs_path_from_package_dir('examples_projects')) File "C:\Users\willa\miniconda3\envs\pyoccenv\lib\site-packages\ryven\gui\startup_dialog\StartupDialog.py", line 122, in open_project project_str = f.read() File "C:\Users\willa\miniconda3\envs\pyoccenv\lib\encodings\cp1252.py", line 23, in decode return codecs.charmap_decode(input,self.errors,decoding_table)[0] UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 161607: character maps to

Would this be different for Anaconda vs. Miniconda?

When we load an existing project (*.json file) the 3D viewer window launch freeze the load of the project itself. Conflict between Ryven and the 3D viewer?

The only way I get to open an existing project is to comment this line in nodes.py :

display, start_display, add_menu, add_functionto_menu = init_display() to #display, start_display, add_menu, add_functionto_menu = init_display()

and when the project is loaded uncomment it.

Detailed changes:

I resturtured the files into dirs (examples, nodes package).

I cleaned the nodes package and made a few chanes, in particular:

• I don't see why the node base should include behavior like having a dynamic number of inputs, most of your nodes are not intended to include that behavior. For example, your display node was crashing under the hood all the time because the node base class tried to set a value to a non-existing output, etc. In fact, I found only one node so far which can make use of this behavior (the List_Node). I changed implementations accordingly.
• I added labels to inputs
• Some descriptor renaming (like dir which shadows python's dir class, in those conflict cases you usually appen a _).
• Lots of small changes to simplify implementations and provide consistent syntax formatting, I think this is much more readable now.

I did not test every single node, and there are some that are not working 100% as intended, but their behaviour should be mostly equivalent to the old implementations, and your demo example runs without issues.
