NodeBox and Blender

Would it be possible to run the code (that is coming from NodeBox) inside Blender (that is scriptable with python)?

   Not directly, no. The issue is the drawing library: we don't have a graphics API that is compatible with Blender's graphics API.

   If we (or someone from the community) could provide a bridge that links the two, then it would be possible.

   Hi Frederik De Ble...,

   I study the code of Nodebox because I need a python lib for create an addon that use a palette pie with Harmonies pattern like triade or opposite color etc...
   Is it a possibility to code a blender drawing lib to draw with the colors lib of Nodebox?
   or is it possible to use Nodebox OpenGL for that (with python and java).

   "colors lib" is amazing and simple. but contain drawing function from coca for MAC.

   If the drawing lib would be for blender: bpy, bgl, and blf, we must re-writte all the colors lib, no?

   I am very interesting to discuss with you about that, please?
   friendly.

   It's been a while since I've looked at the colors library, but AFAIK it would be possible to just use the color harmony algorithms (which return simple Python data structures) without using the drawing part (which would use the NodeBox drawing API).

   Is there a specific error you run in to?

   >>It's been a while since I've looked at the colors library, but as far as
   I know it would be possible to just use the color harmony algorithms (which
   return simple Python data structures) without using the drawing part (which
   would use the NodeBox drawing API).

   but "ximport" don't run with python because ximport is special to nodebox

   *and colors/__init__.py :*

   try:
       # NodeBox / Cocoa specific functionality.
       # Our library can still do a lot of interesting stuff without these!
       from nodebox.graphics import Grob, RGB, HSB, CMYK, CORNER
       from nodebox.graphics.cocoa import _restore, _save
       from AppKit import NSShadow, NSColor
       from AppKit import CIImage, CIColor, CIFilter, CIVector,
   NSGraphicsContext
   except:
       class Grob: pass

   This don't be used but I have a traceback with it!

   And I tried the first "colors example 1" and I must rewrite the import code
   like this:

   try:
       colors = __import__("colors")
   except ImportError:
       colors = __import__("__init__")
      #reload(colors)

   BUT "reload(colors)" don't run on my Python 3,5!!! Do you have a solution,
   please?

   I tried this "exec.module(colors)" but don't run too!

   Excuse me if I speak of details problems. I wanted to speak only about the
   use of the code with standart python: You answer me there are not problem
   with drawing module so I will try to code my custom bpy, bgl, blf, module
   for your colors module.
   Thanks
   At soon.

   Hi,

   After installed colors folder in Blender python/lib/site-packages/
   and run blender and in console windows, I typed this:

   >>> colors = __import__('colors')
   >>> clr2 = colors.olive()

   Traceback (most recent call last):
     File "<blender_console>", line 1, in <module>
     File "<string>", line 50, in <lambda>
     File
   "C:\Users\lenovo\Downloads\BLENDER\APPLICATION\blender-2.79-rc2-windows64\2.79\python\lib\site-packages\colors\__init__.py",
   line 640, in __init__
       elif kwargs.has_key("mode") \
   AttributeError: 'dict' object has no attribute 'has_key'

   => I don't understand why there are an error?

   OK Frederick,

   I corrected the code with python 3.0 functions because "has_key" for
   example is removed now!
   And the new code run:

   $ colors = __import__('colors')
   $ clr1 = colors.olive()
   $ print(str(clr1))
   $ Color(0.500, 0.500, 0.000, 1.000)

   So I will continue to obtain the code run correctly for python 3.6....
   Thanks.

   Friendly.

   Hi Patrick,

   Do you by any chance have a list of fixes that we could apply to the colors library to have it work in Blender and Python 3?
