Is GH_CPython compatible with Rhino 6 ?

[co-ord]

Hi @MahmoudAbdelRahman ,

Thank you for this pluggin.

One question, is it compatible with Rhino 6 ?

I have followed the instructions from the wiki (.gha and .dll files in libraryfolder + open Rhino as administrator) but:

• no dialogue box appears when opening Grasshopper
• _GHCPython component doesn't appear in Maths>Scripts either.

The only dialogue box that I have is when I double-click on .gha file directly from the library folder, Rhino opens and displays the following message

Is it just me or a Rhino 6 compatibility issue ?

Apologies, I just found that I needed to unblock the components (.gha + .dll) from the document properties. I now have another problem, the component doesn't seem to work. In administrator mode I dropped GH_CPython on the canvas, went to the menu Python>Choose Interpreter and specified the path to my Python interpreter.

I notice 2 things:

• no matter what I do, the welcome message "Hi [myname], How are you ?" doesn't go away and nothing seems to print
• the text editor doesn't indent the code (I have to push 'space' 4 times for indentation)

I tried with different Python interpreters (2 and 3), restarted my computer several times... without success. I would really appreciate some help @MahmoudAbdelRahman .

Upon fiddling with the component I realized that another component had to be plugged-in first (in input) before running a script. It is probably a bug but at least it works.

Another problem that I have now is when I want to loop a script (for an animation) with a timer. With the bundled GhPython component you can set a variable to a specific value and then increment it with a timer (component) like this:

def setup():
    global n
    n = 0

if iDraw:  #iDraw is a boolean toggle
    n += 1
    ouput_ = n
else:
    setup()

However, the very same script in GH_CPython will return the following error: NameError: global name 'n' is not defined

as if setting the boolean to True was erasing all the globals defined in setup(). As a result any form of variable mutation over time seems impossible.

Is there any way to overcome this issue ?

Any help would be immensely appreciated

Hi @solub, Sorry, it doesn't support this feature, because the component is re-run each time the inputs changed. The only solution in my mind now is to save the global variable in a file outside and each time, the file is updated and read. Another solution would be to save the variable in a specific address in memory and each time you update and read the data from this address. https://stackoverflow.com/questions/8250625/access-memory-address-in-python

I hope this would help to solve the problem.
