Are ghpythonlib.components available in WIP in python 3?

Hi I am updating some older Rhino 7 grasshopper code to python 3.9 in Rhino 8 WIP to take advantage of libraries such as networkx an numpy.

I have come across and error in porting code which refers to the gh components in ghpythonlib.components

This code worked for me previously:

import ghpythonlib.components as ghcomp

crv_copy = ghcomp.ExtendCurve(crv_copy, 0, new_ext, new_ext)

now I get this error in my python 3 component in grasshopper:

File “C:\Users\brian.rhinocode\python3.9-31\site-rhinoghpython\ghpythonlib\components.py”, line 150, in component_function
result, warnings = info.Evaluate(args, keep_tree)
TypeError: No method matches given arguments for ComponentFunctionInfoImplementation.Evaluate: (<class ‘tuple’>, <class ‘bool’>)

Does anybody have any suggestions at all?

Many thanks,

Brian

@brian9 I also see that. I made a new bug report for this, tracked here: RH-76559 ScriptEditor Python 3.9: ghpythonlib.components do not work

Having the same problem with other functions of ghpythonlib.components from within Python3…

Hi sorry for not responding to this thread I’ve had an extended hiatus on the project I was porting to Rhino8 WIP. I have found another very similar error in using ghcomp:

.rhinocode\py39-rh8\site-rhinoghpython\ghpythonlib\components.py", line 163, in component_function
elif len(result) > 1: result = __namedtuple(outputnames, result)
File “C:\Users\brian.rhinocode\py39-rh8\site-rhinoghpython\ghpythonlib\components.py”, line 61, in init
raise TypeError(
TypeError: Expected type Array[str] for input ‘attributes’, got IReadOnlyList[String].

code that caused this:
import ghpythonlib.components as ghcomp

paired_crv, flag = ghcomp.FlipCurve(paired_crv, crv)

This is in 5/10/23 update of grasshopper

actually, sorry it’s 1.0.0007 from Friday 13/10/23 and I’m finding this with any ghcomp call eg.

geom, transf = ghcomp.Move(move_crv, move_vec )

I appreciate that in hindsight I should have done everything in rhinocommon, but it was easier to quickly work with the gh components I already new and now I have a big code maintenance problem and re-write on my hands if ghcomp isn’t going to be a feature going forward
